Fast, Reliable General Contractor Across San Jose
Most San Jose homeowners ask us the same three questions before any remodel: who is coming to my door, what will it actually cost, and what happens if something goes wrong. Here are the straight answers. Every Mason Remodeling crew member is background-checked, identity-verified, and introduced to you by name and photo before they arrive in a marked uniform with a photo ID badge. You get a written price before any work starts, on every project, and every job is covered by our 365-Day Done Right Promise. Isaac Pruett leads our team, and a live person answers when you call (803) 680-2547.
We work across San Jose daily, from Willow Glen ranches to Rose Garden colonials to the newer builds climbing the East Foothills. Local work means knowing that a 1958 home off Pine Avenue hides different conditions behind its walls than a 1990s Evergreen tract house. That knowledge changes the bid, the schedule, and the final result. Call us for a free estimate, and we’ll scope the job in writing.
Why Mason Remodeling Is San Jose’s Preferred General Contractor Company

San Jose homeowners tend to be detail-oriented. Many are engineers, project managers, or tech professionals who read specs for a living, and they can spot a vague bid from across the room. That’s why we lead with a written scope of work on every single project, before a tool is unpacked. No verbal estimate that grows on the final invoice. No handshake allowances. Just a line-item price you can hold us to.
As a Threshold Group construction company, we operate under what we call The Threshold Standard. Every technician is background-checked, identity-verified, and arrives in a clean marked uniform. You receive their name and photo before the visit, and they show a photo ID badge at the door. If you’re home alone or have young kids, you don’t open the door to a stranger. You open it to someone you were expecting, whose name you already know.
Our reputation in San Jose is built on finishing work that passes inspection and stays finished. We don’t chase change orders, and we don’t cut corners on rough-in that nobody sees. We carry specification-grade lines like KraftMaid and Wellborn cabinetry, Cambria and Silestone surfaces, and Kohler and Moen fixtures. That matters when you’re spending five figures and want the work to last.
When you work with our General Contractor team, you get the same written guarantee on every project. Coverage terms are stated plainly, including what’s covered, what’s excluded, and for how long. 365 days from the completion date. If something isn’t right, we return and make it right at no cost to you. That’s not a promotion. It’s the deal.
Styles & brands we work with







Residential General Contractor in San Jose
Residential General Contractor work in San Jose means something specific: you’re hiring one firm to coordinate the demo, rough-in, finishes, inspections, and punch list on a project inside your home. Most San Jose homeowners bring us in for kitchens and bathrooms, but we also handle window replacement, room additions, and whole-home remodels. On a typical kitchen remodel, expect to invest $16,520 to $53,100 depending on cabinet grade, countertop material, and whether walls move.
Written Scope, Not a Walkthrough Guess
Cheap bids in San Jose usually come from a 20-minute walkthrough. The contractor writes “replace kitchen” on a napkin and hopes for the best. We write a scope of work that names every cabinet line, every slab allowance, every fixture. You know what you’re buying, and the price doesn’t float when we open the walls.
Permits Handled As Standard
San Jose runs its own building division, and we pull permits on every job that requires them. That means the inspection sign-off at the end is real, not optional. If you sell the house in five years, the work is on the record. That’s how it should be.
Hire a General Contractor in San Jose

When you Hire a General Contractor in San Jose, the decision comes down to trust and paperwork. Trust, because you’re letting people into your home while you’re at work or while your kids are napping. Paperwork, because a five-figure remodel should never rest on a verbal quote. We deliver both. A bathroom remodel in San Jose typically runs $10,620 to $33,040. A home addition is $53,100 to $153,400. Those are real ranges, not teaser numbers.
Who Shows Up Matters
We don’t subcontract to unknown crews. Every person on your job is a Mason Remodeling employee or a vetted trade partner who meets The Threshold Standard. You get names, photos, and no surprises. That’s non-negotiable for us.
The 365-Day Done Right Promise
Here’s how it works. If something we installed or built fails within 365 days of the completion date, we return and fix it at no charge. No dispute process, no conditions, no fine print. The same promise applies to general contracting, bathroom remodeling, and whole-home remodels. Written guarantee on every project, stated plainly.
Founded in 2004 as part of the Threshold Group family of home-service companies, we’ve spent two decades learning what San Jose homeowners actually need.

AfterCommon General Contractor Problems We See in San Jose Homes
- Bids scoped off a walkthrough instead of a written scope of work. A contractor walks through, quotes a number, and six weeks later the Cambria allowance “ran out.” We write the scope before we write the price, and material allowances are named upfront.
- Skipping San Jose permits on kitchen and bath work. Homeowners are told “it’s just cosmetic, no permit needed.” Then a resale inspection stalls because the water heater relocation or electrical rough-in was never recorded. We pull the permit when it’s required, and it’s not optional.
- Ignoring pre-1960 construction conditions. Many Willow Glen, Rose Garden, and Alum Rock homes have original cast-iron drains and failed subfloor under the sink. These change the rough-in cost once walls open. We plan for it. Cheaper bids pretend it doesn’t exist.
- Change orders that arrive as surprises. A contractor finds rotted framing and hands you a five-figure bill on the spot. We document conditions during demo, flag issues in writing, and get your approval before any added scope. You never pay for something you didn’t approve.

What moves a bid? Cabinet line, countertop slab, whether you’re moving plumbing or leaving it in place, and the condition of what’s behind the walls. On a 1958 ranch off Pine Avenue, we gutted a galley kitchen, replaced the failed plywood subfloor under the sink, ran new rough-in for a KraftMaid cabinet layout, and set a Cambria quartz island. The scope of work, allowances, and one change order for added soffit removal were all documented in writing before the punch list. The quartz island landed inside the $3,540 – $11,800 island range, and the whole job passed inspection sign-off. Call (803) 680-2547 for a free estimate, and you’ll get the same written treatment.

FAQs About General Contractor in San Jose
It depends on scope, but in San Jose, most interior remodels that don’t move load-bearing walls, add square footage, or touch the building envelope clear over-the-counter permits at the city’s building division. Anything involving an ADU, a hillside lot, or structural changes gets pulled into San Jose’s separate planning review first, a step that doesn’t exist the same way in Santa Clara or Campbell. We determine the permit path as part of your written scope, before work starts. Call (803) 680-2547 and we’ll tell you exactly what your project requires.
Because most cheap bids are scoped off a 20-minute walkthrough with no written allowances, no permit line, and no allowance for what’s behind the walls. The price looks low, then grows once the subfloor is exposed or the Cambria slab gets upgraded. A real bid names the cabinet line, the countertop allowance, the fixture set, and the permit cost, and it stays put. Our written price is delivered before any work starts, on every project, every time.
A typical 5×8 San Jose bathroom remodel runs 3 to 5 weeks from demo to final inspection, assuming you’re not moving plumbing drains or load-bearing walls. A larger primary bath with custom tile, a walk-in shower, and plumbing relocation can run 6 to 8 weeks. San Jose’s permit review adds time if the project triggers planning review, which happens more often here than in neighboring cities. We give you a calendar in writing as part of the scope, and we update it if conditions change. Call (803) 680-2547 for a free estimate with a realistic schedule.
Cast-iron drains, rotted subfloor, asbestos in old flooring, and non-compliant electrical are the big four in Willow Glen, Rose Garden, and Alum Rock homes built before 1960. You can’t see any of them until walls open. We flag these conditions during demo, document them in writing, and get your approval before any added scope. You never pay for a surprise. A cheaper contractor will either ignore the condition or bill you on the spot. We do neither.
Yes. ADU construction in San Jose runs $106,200 to $259,600, and home additions run $53,100 to $153,400. San Jose’s planning review for ADUs and hillside lots is stricter than most Bay Area cities, so the pre-construction phase takes longer and costs more up front. We handle the full process: design coordination, planning submittal, permit pull, construction, and final inspection sign-off. Call (803) 680-2547 and we’ll walk you through what your lot can support, what it costs, and how long it takes. Estimates are free.
