The floor is the specialty.
The remodel comes with it.
Flooring is where we do our best work — and as a Class B general building contractor, we take it on as part of the bigger job: the paint, the kitchen, the bath, or the whole remodel. Free on-site estimates on every job.
Hardwood & engineered wood
New installs, replacements and refinishing — solid and engineered planks, laid straight, gapped right, finished clean.
Our most-requested trade
Vinyl plank & laminate
Waterproof LVP and laminate systems for kitchens, rentals and busy households — durable floors on a working budget.
Popular in rentals & family homes
Tile floors
Porcelain and ceramic tile for kitchens, bathrooms and entryways — level substrate, tight lines, sealed grout.
Done alongside our bath remodels
Kitchen, bath & home remodels
Single rooms to whole-home remodels under our own Class B license — permitted and signed off by the city.

Painting
Interior and exterior painting — the finishing pass on your floor or remodel project.

Home repairs
Squeaking boards, water-damaged sections, drywall, doors, trim — the small jobs other contractors won't pick up.
If a repair will do, that's what we'll quote
As a Class B general building contractor, we contract flooring together with the other work your project genuinely needs — paint, trim, kitchen or bath. Flooring-only job? Call and we'll tell you straight who should do it.

Ballpark in 30 seconds
What would your floors roughly cost?
Slide to your square footage, pick a material, and get an honest range — then book the free visit and we'll put the exact number in writing. The ballpark prices the flooring portion of your project; we contract floors together with the paint, trim or remodel work around them.
Rough is fine — a bedroom is about 120–150 sq ft, and your Zillow/Redfin listing has the exact number. We measure for real at the free visit.
Real wood, solid or engineered planks — the classic warm floor.
Sample ranges for a first idea only — every home is different. Your real number comes as a written quote after the free on-site (or video) visit, and if a repair will do, the quote says repair.
