Fast, Reliable General Contractor Across San Martin
Most San Martin Home Remodeling work carries a real price range of $14,000 to $130,000 depending on scope, and the honest answer is that a kitchen remodel, bathroom remodel, room addition, or deck construction should never be quoted from a photo alone. San Martin properties aren’t like San Jose or Campbell houses on city water and sewer. Many sit on private wells and septic systems, which changes what permits you need and how long the job takes before the first wall comes down. We know because we’ve worked through it, house by house, on lots that run from a half-acre to five-plus. Call (803) 680-2547 and you’ll get a live person, a straight answer, and a written price before any work starts.
Why Mason Remodeling Is San Martin’s Preferred General Contractor Company
Our General Contractor team has handled projects across San Martin that started exactly where yours will: with questions about wells, septic capacity, county permits, and what the real number will be. Isaac Pruett leads the work, and every crew member who walks onto your property has been background-checked, identity-verified, and introduced to you by name and photo before the visit. That’s the Threshold Standard, and it matters most to homeowners who are often home alone, parents with young kids, and older adults who take opening the door seriously.
We don’t hand you a handwritten number and hope it holds. Every project gets a written price delivered before tools come off the truck. On a San Martin kitchen remodel, that written price includes the line items for KraftMaid cabinetry or Silestone counters, not a vague “allowance” that drifts upward later. If something changes mid-job, you get a change order with photos and a fixed price. No verbal additions. No end-of-project surprise invoice. And every completed project carries a written guarantee for 365 days from the completion date, with the terms stated plainly, including what’s excluded.
Styles & brands we work with
General Contractor Services in San Martin
General Contractor Services in San Martin cover the full run of structural and finish work on a home: kitchen remodels, bathroom remodels, whole-home remodels, room additions, basement finishing, and deck construction. What makes this specific market different is the permit layer. Nearly every significant project on a San Martin property triggers Santa Clara County involvement, and when the home is on a private well and septic system, the county often requires a septic capacity letter and well-yield verification before the building permit gets issued. A general contractor who hasn’t worked through that process will discover it mid-project and hand you the cost. We build that into the plan from day one.
Kitchen and Bathroom Remodeling
A full kitchen remodel in San Martin runs $14,000 to $45,000, and the biggest cost drivers are cabinet grade, countertop material, and whether you move plumbing or gas lines. A bathroom remodel runs $9,000 to $28,000. We spec brands like Wellborn, Cambria, Silestone, Kohler, and Toto from our material partners, so the number you sign is the number those materials actually cost.
Additions, ADUs, and Garage Conversions
Home additions in San Martin range from $45,000 to $130,000. ADU construction runs $90,000 to $220,000, and a garage conversion lands between $30,000 and $80,000. These are the projects where the well-and-septic reality matters most, because septic capacity directly limits how many bedrooms or plumbing fixtures the county will approve.

Construction Company in San Martin
Construction Company work in San Martin is a broader category than remodeling alone. It includes room additions, ADUs, whole-home remodels, and structural changes that require working with Santa Clara County from the first plan review through final inspection. The county permit path for an addition on a private septic system can extend the pre-construction timeline by weeks, not days, and a contractor who lets that slip will blame the county later. We hold the schedule against it from the start, so you know when demo begins and when the final inspection is scheduled.
Permits, Inspections, and the County
Every major project we handle in San Martin gets its permits pulled properly, and every inspection gets passed before the next phase moves forward. We don’t skip rough-in inspections to save a day. We don’t frame walls and hope nobody asks about the septic capacity letter. The county will ask. We have the letter before the building permit goes in.
A Real San Martin Project, Start to Finish
We recently finished a kitchen remodel on a San Martin property where the homeowner wanted KraftMaid cabinetry, a Cambria island, and new Kohler fixtures. Before demo, our crew mapped the existing well-fed plumbing and found the subfloor had old water damage that wasn’t in the original scope of work, so we issued a change order with photos and a fixed price. The project passed its rough-in and final inspection sign-off on the first try, and the punch list was cleared in a single visit.
Trusted Brands We Service in San Martin
San Martin homeowners don’t have to drive to Morgan Hill or Gilroy to see what a Wellborn cabinet line or a Silestone countertop actually looks like in person. Our material partnerships include KraftMaid, Wellborn, Cambria, Silestone, Caesarstone, Kohler, Moen, Toto, Grohe, GAF, CertainTeed, Owens Corning, Belgard, Unilock, and Techo-Bloc. We also work around the newer prefab and ADU players in the South County market, including Abodu and Dvele, when a homeowner wants a panelized or factory-built path for an ADU or addition. For San Martin jobs, our crews stock the parts and materials those brands require, so turnaround on change orders and corrections doesn’t stall the calendar. The point is that a written line item for “Kohler Purist faucet” is a real price, not a placeholder that becomes a different fixture on install day.

AfterCommon General Contractor Problems We See in San Martin Homes
- Well and septic unknowns on additions and ADUs. Santa Clara County requires a septic capacity letter and well-yield verification for many additions and most ADUs. A contractor who bids from photos won’t check this until after you’ve signed, and the letter can change the size of the project the county will approve.
- Vague allowances that explode the budget. A contract that says “allowance for cabinets: $5,000” with no brand, no line item, and no written change-order process means the real cost lands on you at selection time. Silestone, Wellborn, and Cambria products vary widely in price, and “allowance” language hides that.
- No draw schedule before work begins. Payment timing should be written down: what’s due at contract signing, what’s due at rough-in inspection, what’s due at final inspection. Without it, the homeowner and the general contractor will disagree exactly when a material delivery or an inspection slips.
- Wood rot and subfloor damage hidden under old finishes. San Martin’s older ranches and farmhouses often carry decades of slow leaks around windows and plumbing. The damage doesn’t show until demo opens the floor or the wall, which is why a written change-order process with photos and fixed pricing matters more than a low initial bid.

FAQs About General Contractor in San Martin
Any remodel that changes plumbing, electrical, gas lines, or structural walls in San Martin requires a Santa Clara County permit, and most kitchen and bathroom remodels touch at least two of those. Cosmetic-only work like painting or replacing a faucet in kind typically doesn’t. When we write your estimate, we tell you exactly which permits apply to your project and include the permit coordination in the schedule. Call (803) 680-2547 and we’ll walk you through what your specific scope triggers.
It affects two things: what the county will approve and how long the pre-construction phase takes. For additions and most ADUs, Santa Clara County requires a septic capacity letter confirming the system can handle the added bedrooms or plumbing fixtures, plus a well-yield verification in many cases. Until those documents clear, the building permit won’t issue. We factor that into the timeline from the first site visit, so it’s not a surprise cost later. Call (803) 680-2547 if you’re considering an addition and want to know what your septic system will support.
At minimum: a written line-item price for the full scope, the brand and model of every major material, a draw schedule tied to inspections, a written change-order process with fixed pricing for any added work, and the guarantee terms, stated for 365 days from the completion date. Anything less than that is a verbal estimate that will grow on the final bill. That’s the standard we deliver on every job. Call (803) 680-2547 for a written estimate on your project.
Most kitchen remodels in San Martin run six to ten weeks from demo to final inspection, depending on whether you move plumbing or gas and how quickly your cabinet and countertop selections are ordered. Add two to four weeks if the project requires septic or well documentation before the permit clears. We give you a calendar at contract signing, not a promise that drifts later. Call (803) 680-2547 and we’ll give you an honest timeline for your scope.
One thing only: a change you request or a condition demo reveals that wasn’t visible when the contract was written, like the subfloor water damage behind an old waterproof floor. In that case, we stop work, document the issue with photos, hand you a written change order with a fixed price, and proceed only after you approve it. No surprise invoices, no verbal add-ons. Call (803) 680-2547 to schedule a free estimate before you sign with anyone.
