Fast, Reliable General Contractor Across Martinez
Most Martinez homeowners calling a general contractor for the first time are not looking for a slogan. They are looking for someone who will show up, look at the actual house, put the real scope in writing, and then do the work without turning the project into a second career. That is what we do. We know Martinez streets like Alhambra Avenue, Morello Heights, and the older blocks downtown near Las Juntas Street. We know what a 1950s ranch on a hillside lot needs that a 1980s track home on the flats does not. If you are planning a kitchen remodel, bathroom remodel, room addition, or a full home renovation, call (803) 680-2547 and we will walk the project with you, scope it honestly, and put a written price in your hand before any tool leaves the truck.
Why Mason Remodeling Is Martinez’s Preferred General Contractor Company
Martinez homeowners keep calling us back because we treat the front door the way you do: as a security decision. Every crew member on a Martinez job is background-checked and identity-verified under the Threshold Standard. Before the visit, you get the technician’s name and photo. At the door, they show a photo ID badge and arrive in a clean, marked uniform. No strangers in your hallway, ever. That matters a lot to people home alone during the day, parents with young kids, and older adults who do not want to guess who is knocking. Isaac Pruett leads our team, and he has built Mason Remodeling around a simple rule since 2004: the price is written before the work starts, and it does not drift. Our Martinez customers get a written guarantee on every completed project, with terms stated plainly, and a free return visit if anything goes wrong. No dispute hotline, no fine print runaround. Just a second trip at no charge, no conditions.
One more thing and it is specific to Martinez. We are part of the Threshold Group family of home-service companies, which means the same verification standard applies on a $5,000 small bathroom remodel and a $130,000 home addition. A live person answers our phone around the clock, every day including weekends and holidays. When a Martinez homeowner calls at 7 a.m. before work, a human picks up. Not a call tree.
Styles & brands we work with
Hire a General Contractor in Martinez
Hire a General Contractor in Martinez when the job touches structure, plumbing, electrical, load-bearing walls, or anything that needs a permit and an inspection. That covers kitchen remodels, bathroom remodels, room additions, garage conversions, and ADU construction. Our General Contractor team starts every Martinez project the same way: a site walk, a written scope of work, and a line-item price before permits are pulled. In Martinez, a kitchen remodel typically runs $14,000 to $45,000. A bathroom remodel runs $9,000 to $28,000. A home addition starts around $45,000 and can reach $130,000 depending on foundation work, roofline changes, and finish level. Those are honest ranges for this market, not teaser numbers.
Permits and Plan Check in Martinez
Martinez requires building permits for structural changes, and the plan check process in Contra Costa County can catch things you would not expect. If your home predates 1970, the original permit history may be thin or missing entirely. That means unpermitted prior work can surface during plan review, and you need a contractor who budgets for corrections instead of acting surprised later. We do.
Draw Schedule and Change Orders
We tie payments to milestones: demo, rough-in, inspection sign-off, and punch list. That keeps the job moving and keeps you in control. If a scope change happens mid-job, it is a written change order with a price before the work continues. Never a verbal “we’ll settle up later.”
General Contractor Services in Martinez
General Contractor Services in Martinez cover the full sequence of a remodel: demolition, rough framing, plumbing and electrical rough-in, drywall, finishes, and final inspection. We coordinate the trades, pull the permits, schedule the inspections, and hold the job to the written scope. If you are updating a 1960s rancher near Hidden Lakes or building an addition on a hillside lot in Alhambra Valley, the sequence is the same. What changes is what the house gives us once we open the walls.
Kitchen and Bath Remodels
Most Martinez kitchen remodels are full gut jobs on homes built between 1940 and 1975. That means galvanized supply lines, cast-iron drains, and sometimes knob-and-tube wiring. We scope for those before we write the price. A small kitchen remodel in Martinez runs $9,000 to $20,000. A small bathroom runs $5,000 to $12,000. Full kitchens and baths land higher, and we will show you exactly why in the line items.
Additions, ADUs, and Garage Conversions
Martinez lots vary a lot. Some are flat and rectangular. Others climb steeply into the hills. A garage conversion on a flat lot runs $30,000 to $80,000. An ADU runs $90,000 to $220,000 depending on whether it is attached, detached, or a conversion. A home addition runs $45,000 to $130,000. Foundation scope dictates most of the swing. We will tell you what your specific lot requires before you sign anything.

Trusted Brands We Service in Martinez
We specify products we can stand behind and that hold up in Martinez’s climate, with its cool, damp winters and hot inland summers. For cabinetry, we work with KraftMaid and Wellborn. For surfaces, Cambria, Silestone, and Caesarstone. Fixtures from Kohler, Moen, and Toto. Roofing from GAF and CertainTeed. For a recent hall bathroom in Martinez’s Alhambra Valley area, we replaced a cracked cast-iron drain, opened the subfloor, and installed a Kohler valve and Cambria vanity before inspection sign-off. We order directly through our supplier accounts, which means Martinez customers get pro-grade materials without a middleman markup and without waiting on a big-box backorder.

AfterCommon General Contractor Problems We See in Martinez Homes
- Galvanized supply lines and cast-iron drains: Pre-1970 Martinez homes often still run original plumbing, and it is usually at the end of its service life. We budget for replacement in the initial scope, not as a surprise change order after demo.
- Unpermitted prior work: Martinez’s downtown and hillside neighborhoods have a long history of owner-built additions and DIY electrical. When we pull permits, the city sometimes flags that prior work, which means corrections before the new scope can be signed off.
- Hillside foundation movement: Lots above Alhambra Avenue and in the Alhambra Valley can shift with seasonal moisture. We check footings and stem walls before framing an addition, because the cost of a bad foundation shows up later as cracked drywall and sticking doors.
- Undersized framing on older remodels: Some Martinez homes were built when code allowed smaller headers and fewer shear walls. Opening a wall can trigger a structural upgrade at plan check. We identify that early, not after the drywall is down.

We bid from a written scope of work with allowances for tile, fixtures, and cabinetry stated plainly. When the scope changes, the change order is written and priced before the work continues.

FAQs About General Contractor in Martinez
Yes, almost always. Any structural work, plumbing, electrical, or change to the building envelope requires a permit in Martinez. We pull all permits for you and handle the inspections. If you are only swapping finishes like paint, flooring, or a vanity without moving plumbing, you may not need one, but we will confirm that in writing before work starts. Call (803) 680-2547 to get a straight answer for your specific project.
A general contractor runs the whole project: scope, permits, trade coordination, materials, schedule, inspections, and the final punch list. On a Martinez remodel, that means one person is accountable for the plumbing rough-in, the electrical, the drywall, the tile, and the final inspection sign-off, instead of you chasing four different subs. That is the job. Get your written scope and price by calling (803) 680-2547.
A small bathroom usually runs three to five weeks. A full kitchen runs six to ten weeks depending on structural work and cabinet lead times. Additions and ADUs run three to six months or more depending on foundation scope and plan check. Martinez plan check can add two to four weeks on older homes with prior unpermitted work. We give you a calendar with milestones before work starts, and we stick to it. Call (803) 680-2547 for a realistic timeline on your project.
Three things typically: what we find behind the walls, what the city requires at inspection, and what you choose during allowance selections. A rotted subfloor, a galvanized drain that needs full replacement, or a plan-check correction on prior unpermitted work can all change the price. Our written change orders are priced before the work continues. We do not run surprise invoices at the end. Call (803) 680-2547 to get a written estimate that accounts for the likely conditions in your Martinez home.
Payments are tied to milestones: a deposit to schedule, then draws at demo, rough-in, inspection sign-off, and final punch list. You always know what you are paying for and when it is due. We do not ask for full payment upfront and we do not let a bill show up without a corresponding milestone. Call (803) 680-2547 to see a sample draw schedule for your project.
