A General Contractor Who Knows Sammamish Homes

Sammamish's housing stock is what shapes every remodel decision here. Sammamish is one of the newest cities in King County, and the housing reflects that — predominantly 1990s through 2010s construction in master-planned subdivisions like Klahanie, Trossachs, and the Pine Lake area. Most homes are 3,000–5,000+ square feet with engineered framing, modern electrical service, and large open floor plans. Most projects here are high-end finish upgrades or primary suite expansions rather than gut overhauls.

Sammamish is roughly a 30–35 minute drive northeast of our Kent base via I-405 and SR-202. That proximity matters — when materials show up damaged or an inspector needs a same-day correction, we are not driving in from Seattle.

What's Included

Everything a Home Remodel Touches — All Under One Contract

Home remodels are bigger than any single trade — they require sequencing, structural awareness, and one person who owns the whole timeline. That person is us. Below is what's typically included in a Sammamish home remodel; scope varies dramatically by project.

Whole-Home Renovations

Gut renovations, multi-room refreshes, and "down to the studs" projects. Sequenced room-by-room when you need to live in the home during work.

Additions

Square-footage additions including primary suites, bonus rooms, mudrooms, and bump-outs. Foundation, framing, roof, and finish work all in-house.

Layout Changes

Wall removal, structural openings, and footprint reconfiguration. We work with structural engineers to spec engineered beams when needed.

Flooring

Hardwood, engineered hardwood, LVP, tile, and refinishing existing hardwoods. Multi-room flooring projects coordinated with furniture move-out.

Paint, Trim & Doors

Interior and exterior paint, custom trim and millwork, baseboard, casing, crown, and new interior or exterior doors.

Windows

New window installation, retrofit replacements, larger-opening upgrades, and trim/sill work that matches existing.

Structural Work

Engineered beams, post replacement, foundation repair, and load-path corrections under permit and inspection.

Multi-Room Projects

Kitchen + primary bath + flooring + paint in one coordinated project — sequenced so subs do not step on each other.

Permits & Inspections

We pull City of Sammamish permits for all structural, electrical, plumbing, and mechanical work and schedule every inspection.

Sammamish Permits & Considerations

What to Know Before You Start

The City of Sammamish requires a building permit for virtually all home remodels beyond cosmetic paint and flooring. That includes structural changes, additions, window enlargements, electrical or plumbing alterations, and most layout reconfigurations. Larger projects also trigger plan review, energy code compliance, and sometimes mechanical permits.

We pull every required permit through the Sammamish Permit Center, manage plan review, coordinate inspections at each phase (foundation, framing, rough-in, insulation, final), and keep complete documentation in your project file. Unpermitted home remodel work is a serious resale liability — appraisers and inspectors catch it.

  • Permits filed with the City of Sammamish under our license, not yours
  • Rough-in and final inspections scheduled and met on-site
  • Sammamish has stringent stormwater and critical-area regulations — relevant on any addition or footprint change
  • Klahanie and Trossachs HOAs have specific architectural review processes we navigate as part of every project
  • Permit copies handed to you at close-out for resale records
