What Should Be Included In A Remodeling Estimate Before You Sign?

I'm Sam Brenich, Chief Marketing Officer at New Day Construction. Through my work with our team, I've seen how much remodeling estimates can vary, even when homeowners are planning similar projects. One of the biggest concerns homeowners have is why two contractors can give such different estimates for what appears to be the same remodeling project. A bathroom quote at $50,000 looks a lot better than one at $80,000, right up until the final invoice shows $100,000.

I wrote this guide for the homeowner who is starting home remodeling and wants to understand what each line means. It's not a manual for pricing or building a remodel yourself. In Washington, contractors must be registered with the state, and plumbing and electrical work must be done by certified tradespeople. But the person paying for the work should still be able to read the proposal and ask informed questions at every stage.

New Day Construction builds across King and Snohomish counties, which means the permit notes and price ranges below come from jobs near you. The ranges are approximate benchmarks from our team, with your written estimate beating any table you find online.

Why Two Estimates for the Same Remodel Can Land $30,000 Apart

If a contractor quotes a bathroom at $50,000 and finishes it at $50,000, that's a great price, and you should hire him even if we came in at $80,000. The trouble starts when $50,000 turns into $100,000 by the end. So the useful question about any quote is how firmly the contractor can commit to it and how much of the real scope it covers.

At New Day Construction, staying on budget and on schedule is one of our main priorities. If we estimate a kitchen at $100,000, our goal is to finish close to that figure rather than let the price climb to $160,000. Homeowner-requested changes and hidden conditions discovered during construction can affect the final cost, which is why we explain those possibilities before work begins.

We've seen how a lower initial bid can become a much more expensive project. On one home addition, we provided an estimate of approximately $300,000, but the homeowner chose another contractor with a lower bid. Six months later, he contacted us again. He had already paid around $300,000, yet the project was only about halfway complete. He asked whether we could take over, but we declined because we couldn't verify the quality or full scope of the work already performed. This is why I encourage homeowners to understand what an estimate includes before comparing the final numbers.

What Should Be Included in a Contractor's Estimate

A one-page estimate with three lump sums is a guess with a logo on it. A useful estimate reads like a map of your remodeling project, and it works in layers.

Scope of the Project, Written So You Can Picture It

Start here, because every other line hangs on the scope of the project. The estimate should name each room and say what comes out and what goes in. Demolition and haul-away, structural work, plumbing and electrical rough-in, drywall, tile, flooring, and painting all need their own line or a clear note about who handles them. If the contractor skips a trade you assumed was covered, ask what's included and what's left out. That matters even more on a basement finish, where plumbing and electrical work often extend well past the visible walls.

Ask for a drawing or a 3D rendering too. We build renderings before construction starts, because a picture catches mistakes that a paragraph hides. A short list of exclusions is a healthy sign of transparency, and it makes the estimate clearer to read. No list at all is where surprises like to live. Ask your contractor to mark up the drawing and show you what stays and what is new. If that conversation is hard to have, the estimate will probably be hard to trust.

Materials With Real Names Attached

"Allowance for tile" tells you very little, but "porcelain tile, 2x4 format, installed" clearly states the details. Finish selections change the total cost more than square footage does, and cabinets are the clearest example. The table below shows how far a single decision can stretch a kitchen budget. These are rough numbers from our team as of October 2026.

Tile follows the same pattern, with large-format tile around 2x4 costing about $75 per square foot to install. Switch to small 6x6 tiles across the whole bathroom and installation climbs to ~$95 per square foot, because the crew sets far more individual pieces. Flooring works the same way: floating LVP runs about $11 per square foot all in, around $5 for the material and $6 for installation, while engineered hardwood lands closer to $20 to $22, around $8 for the material and $12 for installation, since it has to be fastened or glued.

Before you sign, ask which lines would change if you picked a different finish. A contractor who can answer that on the spot has usually priced the job properly.

Who Actually Does the Work

Labor is where an estimate can hide the most, and a thorough one shows it by trade. On our jobs, excavation, foundation, plumbing, and electrical normally go to subcontractors, and drywall usually does too. Painting and doors are split between our crew and partners depending on the size of the job. Siding and windows can be handled in-house on a small scope and are subbed out on a large one. Countertops come from a third-party fabricator, while hood vents and some finish installation are on us.

Ask any contractor the same questions. Which trades are subcontracted, and who answers if something fails an inspection? For plumbing and electrical, you can also confirm that the tradesperson is certified through the Washington L&I Verify tool.

A Sample Remodel Estimate Structure

Here is how detailed estimates for a bathroom or kitchen project can be organized. This is a template. It is not a quote from us.

A contractor may combine several lines into one price. What matters is that you can tell what each combined line includes and what gets billed separately. Watch for loose phrases, too. A wall that is "ready for paint" is not a painted wall, so ask who handles painting and when.

Realistic Kitchen and Bathroom Price Ranges

Numbers help you weigh a quote, so here are the benchmarks our team uses when a homeowner asks where a project should land. Projects run above and below these figures, and finishes decide most of the gap.

For whole-home remodeling, we use a separate square-foot benchmark based on the size and scope of the property. A home near 2,000 square feet tends to cost around $160 per square foot. At 3,000 square feet, that drops to about $140, and at 4,000 or more, it settles near $120. Those are very rough numbers, and materials explain most of the spread. A fully custom kitchen inside a whole-home project can approach $250,000 by itself.

When a contractor gives you a number, ask which finish level it assumes. A $60,000 kitchen with semi-custom cabinets and a $60,000 kitchen with custom cabinets are not the same project, even if the headline looks identical.

Please note that we build full remodels, so the smallest bathroom project we take on is about a powder room near $20,000. If you only need a tub replaced in a day, a bath fitter company will do it cheaper and faster. If you only want a new hood vent over the stove, call a handyman. Hiring a professional remodeler for a job that small costs you more than it should, and our expertise is better spent on full rooms. For more on how we handle each room, see our kitchen remodeling and bathroom remodeling pages.

Allowances and Unexpected Conditions in a Remodel Estimate

No estimate can see inside a wall. A good one says so, and it explains what the contractor assumed and what happens when the assumption turns out wrong.

How an Allowance Works and Where It Bites

An allowance is a placeholder amount for something you haven't picked yet, such as tile or lighting. Ask for the allowance upfront and decide which finishes to prioritize before you sign. It becomes a budget leak when the allowance is low and your real choice costs more, since you pay the difference. Consider asking about what each budget allowance includes and whether labor is included. Next, find out what would happen if your selection cost more.

The Wall Everyone Thought Was Non-Load-Bearing

On one of our projects, a wall looked non-load-bearing at the first consultation. After demolition opened it up, the crew found it carried a load. The job then needed a beam, two posts, engineering, and a permit, and that added about $30,000.

We explain this risk before anyone signs. When a wall is in question, the bid reflects our current assumption. If the assumption fails, the homeowner chooses between trimming scope to stay closer to the original budget and carrying on with the original vision for the extra money. Our initial assessment helps us identify potential structural issues, but some conditions can only be confirmed once demolition begins. So ask your contractor a direct question. If a wall turns out to carry load, which choices will I have, and what will each one cost? The answer should arrive before you sign, in writing.

Roof, Rot, and Other Hidden Conditions

Everything we can see and price at the first consultation belongs in the bid. Cabinets and other visible scope shouldn't become surprise charges later. What we can't see is rot, old plumbing, HVAC runs, and the structural integrity of framing, and those are the legitimate reasons for a change order. Each change order should come in writing, with a price and a schedule effect, before the work starts.

If the scope touches the roof, for example, an addition that ties into existing framing, the estimate should state its assumption about that framing. Standalone roof work isn't something we take on, since roof work for us comes only as part of a larger project. A written change order should name what changed, why it changed, what it costs, and how many days it adds. If you can't find those four items on the page, ask for a revised version before you approve anything.

The 30% Rule and a Cushion for the Unexpected

You'll hear about a "30% rule" for remodeling. It suggests spending no more than 30% of your home's value on renovations, and it's only a loose guideline that you can bend. It helps most when resale is on your mind.

A separate habit protects you from the unexpected. Many sources suggest setting aside 10% to 20% of the budget for surprises that arise mid-job. On a $60,000 kitchen, that cushion is $6,000 to $12,000. Older homes sit toward the top of that range.

Timeline and Permits Before the First Hammer Swings

Two things control a schedule more than anything else: whether the house is empty and how long your city takes to approve the permit.

Phase Planning When You Stay in the House

Kitchens typically take 6 to 10 weeks, with bathrooms from 3 to 6 weeks on our schedule. A whole-home remodel comes down to who lives there. We finished one in about two months because the family bought the house and remodeled before moving in. When a family stays inside, expect 3 to 6 months, as the crew must work in phases.

Be ready for your house to feel like a war zone. The question that matters most is logistics, which means where the kids will be and which rooms stay usable. We work with homeowners to plan construction around their living arrangements whenever possible, whether that means keeping one bathroom available or remodeling different floors in stages. On a current project, for example, a crew is renovating upstairs while the family lives downstairs, and the teams will swap afterward. With three bathrooms, we remodel two and leave one working, then swap. Phasing stretches the timeline and can nudge cost up slightly, since the sequence of work is less efficient.

When you hear a timeline, ask whether it means the crew's working time or the whole period, including design and permit approval. Those can differ by months.

Permit Timing in Seattle and Bellevue

Permit timing swings by city, as some building departments approve in about six weeks and others take up to three months. Seattle usually runs a little longer than Bellevue. You can check current requirements with Bellevue Development Services and the Seattle Department of Construction and Inspections.

Large construction work takes much longer on the front end. For a home addition, architect design runs about one to three months and structural engineering adds roughly two more. Then city review begins. On real addition jobs we have seen permitting stretch from 9 to 16 months. New Day Construction handles Bellevue permitting and inspections as part of project management, so you are not navigating city requirements alone. Still, ask who is responsible for each step and who will tell you when approval comes through.

Payment Schedule and the Fees You Should Ask About

A payment schedule belongs in the written estimate and contract. On our Lake Forest Park project, the homeowner paid in two installments at different stages of construction. Payment schedules can vary by project, so ask your contractor to specify when each installment is due and what work must be completed before payment.

Some homeowners also explore financing. New Day Construction is not a lender. We work with third-party platforms such as Hearth and RenoFi, which let eligible homeowners look at options from independent lending partners. Hearth, for example, may offer personalized options after a soft credit inquiry, with amounts that depend on the lender and product. Rates, terms, and fees are set by those providers, and they can change. Ask for the APR and the origination fee in writing, and ask whether a prepayment penalty applies before you apply.

What to Check in the Contract Before You Sign a Remodeling Estimate

Before you sign, make sure the contract repeats the scope, price, allowances, and payment terms from your estimate, and read it with the same attention to detail you gave the numbers. If something is not in the contract, you can't count on it. Here is what I would check first:

• The contractor's registration number and bond status should match the Washington L&I Verify page. Our Washington contractor license number is NEWDADC823QR, so you can run it yourself.
• For residential work of $1,000 or more, Washington law requires a written Notice to Customer disclosure statement before work starts. It explains the bond and your option to hold back retainage, and it warns about the lien risk if a supplier goes unpaid.
• You can ask for original lien release documents from each supplier or subcontractor.
• Change orders should require your written approval, with the price and the schedule effect stated.
• The warranty should be written down. Review the workmanship warranty included in your contract. Confirm how long it lasts, which types of work are covered, and how warranty issues are handled. Manufacturer warranties on installed materials and fixtures may provide separate coverage.
• The scope in the contract should match the estimate line by line.

Read the Official Notice Before You Receive It

You don't have to wait for the contractor to hand you the disclosure statement. The wording is printed in RCW 18.27.114, so you can read the blank form first. The contractor fills in the registration number and the bond details, and you sign to confirm you received it. Ask who will deliver it and when, so it is not a surprise on the day work begins.

L&I's consumer site ProtectMyHome.net adds a hiring worksheet and tips for checking a contractor before you hire. Washington raised the general contractor bond from $12,000 to $30,000 in July 2024, phased in as registrations renew, so check the amount on the Verify page (L&I announcement). The state's Notice to Customer also warns that the bond is shared across the contractor's work and may not cover every claim, so verify the contractor's active registration, bond, workers' comp account, and any lawsuits against the bond before you sign.

How to Compare Remodeling Quotes Side by Side

Lay two quotes next to each other and the differences often jump off the page. The table below shows what a strong answer looks like and what should slow you down.

The price is only one column. A quote that is far under the others, with a thin scope, usually has something missing.

A Real Estimate in Action, Daniel's Bathroom and Laundry Remodel in Lake Forest Park

Daniel, a homeowner in Lake Forest Park (King County), chose to invest in the last two rooms of his home and came to us on a friend's recommendation, and the friend was another New Day client. His bathroom and laundry room hadn't been touched since the house was built in 1984, while his kitchen had been updated a couple of years earlier with a different contractor. He wanted the last two rooms to match.

We scheduled Daniel's estimate for the following day. Philip visited the property, walked through the bathroom and laundry room, and discussed Daniel's plans for both spaces. Max, our project manager with a background in casework installation, oversaw the project. The 1984 cabinets had held up through four decades of moisture, and the shower tile had been laid before modern waterproofing was standard practice. It looked fine but no longer met today's installation standards, so we demolished and prepped it carefully, which went into the estimate as scope from day one.

We gave Daniel two options so he could weigh the budget against personalization. A semi-custom cabinet remodel came to about $46,000, and a custom cabinet remodel came to about $54,000. Both estimates covered materials, labor, demolition, haul-away, and permits, and no add-on charges appeared during the project. The difference came to $8,000, about 17%, which is often smaller than homeowners expect. To go over the proposal and finalize materials, Daniel visited our Bellevue showroom. He tried the Blum soft-close drawers and compared colors and textures in person. The semi-custom catalog didn't have the finishes he wanted, so he chose custom. He told us other contractors had sent proposals, and that our showroom and professionalism were the second biggest factor in his decision, right after his friend's recommendation.

The work ran from mid-March to mid-May 2026, under two months. The final cost was $54,000, exactly the figure quoted at the estimate stage. Daniel paid in two installments during the project and did not use financing. At project completion, Daniel received warranty documentation covering the applicable workmanship and manufacturer warranties.

FAQ

What should be included in a contractor's estimate?

It should include the scope room by room, named materials and finishes, labor by trade, permit and demolition costs, a timeline, and a payment schedule. It should also list exclusions and any allowances, so you know what the number does and doesn't cover.

What is the 30% rule in remodeling?

It is a guideline that suggests keeping total renovation spending at or below 30% of your home's current value. It works as a sanity check and doesn't replace a budget built from a real estimate.

What are the red flags of a bad renovation contractor?

Watch for a registration number that doesn't check out on L&I's Verify page and a quote with no written scope. Pressure to sign quickly and a vague change-order process are also warning signs. A bid far below every other quote deserves extra questions about what was left out.

What do I wish I knew before my bathroom remodel?

Finishes move the price more than size does, and tile is the best example. Small tiles can push installation from about $75 to about $95 per square foot. I'd also plan early for where your family will bathe when the only bathroom is under construction, and I'd ask about permit timing in your city on day one.

What Costs Are Commonly Excluded From a Remodeling Estimate?

A remodeling estimate should identify any work or costs not included in the quoted price. Depending on the project, exclusions may involve unexpected structural repairs, additional engineering, permit fees, owner-supplied materials, or upgrades beyond stated allowances. Ask your contractor to list exclusions in writing and explain which ones could lead to additional charges.

How should an estimate handle allowances, unexpected conditions, and possible price changes?

Allowances need a stated amount and a rule for what happens when your choice costs more. Unexpected conditions, such as a wall that may turn out to be load-bearing, should be named in the assumptions, and any price change should arrive as a written change order before the work happens.

What should you check in the contract before signing a remodeling estimate?

Check the registration number, the disclosure statement, the warranty, and the change-order process. Make sure the scope in the contract matches the estimate, and read the payment terms before you initial anything.

Should you choose a fixed-price estimate, and can you negotiate it?

A firm price gives you the most certainty when the scope is clearly defined. On kitchens and bathrooms we bid from standard pricing we already know, and the same goes for whole-home remodels. On larger projects like additions we check current subcontractor numbers before we quote. You can negotiate scope and finishes, as Daniel did when he compared a $46,000 option with a $54,000 one. A price that drops with no change in scope usually means something was removed, so ask what changed.
