Every property and every family is different. Pick the one that sounds like you and see what it usually involves.

Major Remodel

Rework the home you already love the location of, from a single kitchen or bath to the whole house.

Best if…

  • You like your lot and neighborhood, but not your layout
  • Your kitchen or bathrooms feel dated
  • You want a fresh home without moving

Keep in mind

  • Moving walls or plumbing can change the scope
  • Bigger jobs may mean planning around construction at home
  • Materials and finishes are the biggest price lever

Pricing, explained

What shapes the price of your project

No two projects cost the same, so we don’t guess from a phone call. We look at your property in person first. Here’s what moves the number.

01

Size & scope

More square footage and more rooms involved means more labor and materials.

02

Finishes & materials

Cabinets, counters, flooring, windows and fixtures can swing a budget more than anything else.

03

Layout & structure

Moving walls, plumbing or rooflines takes more work than keeping things where they are.

04

Site conditions

Slope, access, utilities and what’s already on the lot all affect the build.

05

Permits & city rules

Requirements vary by city, and they shape both the design and the timeline.

06

Timeline

Your schedule and how the work is phased can change how a project is planned.
