Firm Construction is a residential general contractor serving homeowners with new construction, full remodels, and additions — plus select small commercial projects. Electrical and plumbing are certified and handled in-house.
Quality & Craftsmanship You Can Count On
From the foundation up or down to the studs — residential construction is what we do every day, backed by a full general contractor's license.
Ground-up residential builds managed start to finish, from site prep and framing through final finishes.
Kitchens, bathrooms, and whole-home renovations that upgrade the spaces you actually live in.
More square footage without moving — room additions, second stories, and converted space.
Our contractor holds both electrical and plumbing certifications, so the systems behind your walls are installed by our own qualified team — not handed off to whichever sub was cheapest that week. Fewer hand-offs, tighter schedules, one company accountable for the whole job. We also hold a C-7 Low Voltage Systems classification, covering data, security, and smart-home wiring — and we handle small commercial build-outs and tenant improvements on the same basis.
Licensed by the California Contractors State License Board, License #652070. Verify us anytime at cslb.ca.gov — your project is permitted and inspected properly.
Electrical and plumbing certifications mean critical systems are done by our own qualified team, not the lowest-bid sub.
One contractor carries your project from the first walkthrough to the final sign-off, with a single point of contact throughout.
Clear steps, clear communication, no surprises on the invoice.
We visit the site, scope the work with you, and deliver a detailed written estimate — line items, not lump sums.
We handle drawings, permits, and scheduling so the project starts clean and stays compliant.
Licensed crews on-site, certified electrical and plumbing in-house, and a single point of contact throughout.
We walk every detail with you before sign-off. The job is done when you say it's done.
Water, fire, and mold restoration is handled by our restoration division, Scope One Restoration — with the same licensed crews and the same standard of work. Because we're a licensed general contractor, we don't just dry it out and leave; we rebuild it back to finished.
24/7 emergency response for water, fire, and mold damage, including insurance claim coordination.
