Most Newcastle homeowners call us for the same reason. The house sits in a great location, minutes from Bellevue and Renton, but the kitchen and bathrooms still belong to another decade. Newcastle's proximity to our Bellevue base keeps our crews close to the job, which helps when a site visit can't wait. New Day Construction is a design-build remodeling firm and general contractor based in Bellevue. We remodel in Newcastle, WA, and the Greater Seattle area, from a powder room up to a whole-home renovation, and we promise one thing above all. On budget, on time.

Remodeling Services in Newcastle, WA
Most of our work is kitchen and bathroom remodels and whole-home projects. Larger jobs include additions and ADUs.
Kitchen Remodeling in Newcastle
A kitchen is where most Newcastle clients begin. We settle the layout first, then the cabinet selection, since cabinets swing the budget more than anything else. Semi-custom cabinets can land near $20,000, while a fully custom set can reach $50,000 to $60,000. We also plan the lighting, appliance placement, and plumbing fixtures, and we order countertops through a trusted fabricator. See our kitchen remodeling page for more.
Bathroom Remodeling in Newcastle
We remodel bathrooms from powder rooms to luxury primary suites. When an addition changes the exterior, we match the siding and windows as part of the same project. Tile drives labor more than most people expect, because small tile means far more pieces for a crew to set. Before tile goes up, walls and floors need to be plumb and level, because tile hides nothing. Details are on our bathroom remodeling page.
Whole-Home Remodel
If your Newcastle home mixes new finishes with 1990s leftovers, a whole-home remodel brings everything to one style. Cabinets, countertops, backsplash, trim, doors, and floor materials all match. When the budget is tight, we phase the work and finish the kitchen and living areas first, then the bedrooms later. If walls are open anyway, that's the time to talk about insulation and heating and cooling.
Additions and ADUs
An addition usually starts with one question: what the house is missing. The additions we build most are primary suites and expanded kitchen and living space. When an addition changes the exterior, we match the siding and windows as part of the same project. Attached in-law space and detached ADUs come up often too. If an addition opens onto outdoor living space, we plan that transition from day one. See home additions and ADU builders.
What Remodeling Costs in Newcastle, WA
These are New Day's own rough benchmarks as of September 2026, and finishes move every number.
| Project | Rough benchmark |
|---|---|
| Powder room | About $20,000 |
| Standard bathroom (about 4x8) | About $35,000 |
| Primary bathroom | $50,000+ |
| Luxury primary bathroom | $80,000+ |
| Small kitchen | From about $40,000 |
| Medium kitchen | About $60,000 |
| Larger kitchen | About $80,000 |
| Whole-home remodel | About $160/sq ft (to 2,000 sq ft), $140 (3,000), $120 (4,000+) |
These numbers can change depending on layout changes, structural work, cabinetry, tile, fixtures, plumbing and electrical relocation, finish level, permits, access, and project size. Moving a structural wall adds roughly $15,000 to $25,000. Floors matter too. Luxury vinyl plank runs about $11 per square foot installed, while engineered hardwood lands closer to $20 to $22. Large tile installs near $75 per square foot, and small tile pushes toward $95. We don't do one-day tub swaps or handyman jobs. A powder room at about $20,000 is the smallest project we take, and for smaller fixes we'll point you to a better-suited specialist.
Permits, Drainage, and Timeline for a Newcastle Project
Permit timing depends on the city, and in our experience it runs from about six weeks to three months. Additions and structural changes need a permit, and so do most plumbing and electrical changes. We coordinate permit-ready drawings and structural engineering and handle the paperwork.
Larger additions take longer. Architecture usually takes one to three months, engineering about two more, and then city review begins. Some of our addition permits have stretched close to a year. A whole-home remodel takes about two months in an empty house and three to six months when the family stays. With Puget Sound rain and slopes near Lake Boren and Cougar Mountain, we look at drainage early on many Newcastle lots. New Day is a registered contractor in Washington State (license NEWDADC823QR).
Living at Home During a Newcastle Remodel
We tell families up front that an occupied house turns into a war zone during construction. Before demolition, decide where the kids will be and which rooms stay usable. We build around your life about 90 percent of the time. On a current project, we're finishing the upstairs while the family lives downstairs, then they switch, and with three bathrooms, we do two first and leave you one working. Phasing adds time and can add a little cost, but it keeps daily life running.
Why Newcastle Homeowners Choose New Day for Renovation
A low first bid tells you nothing until you see the final invoice. We've watched a competitor's $250,000 addition bid climb to about $560,000 through "unforeseen" work. Better builders put the price in writing and hold it. If we quote a $100,000 kitchen, the final number should stay close to it. It moves when you add scope or when demolition uncovers something nobody could see beforehand. Anything visible at your consultation goes into the bid. The exception is a hidden condition like rot or an unexpected beam, and we explain that risk before you sign.
The Wall That Turned Out to Be Load-Bearing
On one project we priced a wall as non-load-bearing. After demolition it turned out to carry the structure. It needed a beam, two posts, engineering, and a permit, and that added about $30,000. When a wall's status is uncertain, we say up front that the bid assumes it's non-load-bearing. If opening it up proves otherwise, the homeowner can trim scope to stay closer to the original budget or keep the original plan and cover the difference.
