Free written scope consultation - allowances, timeline, and change-order rules on paper before a single trade is scheduled
Fast, Reliable General Contractor Across Brentwood
Most Brentwood remodels stall before a single tool is unpacked. The hold-up isn’t the build itself – it’s the approvals. A kitchen tear-out on Balfour Road or a room addition near Garin Ranch needs City of Brentwood permits, and in most of this planned community, HOA architectural review sign-off before the permit can even be submitted. That’s the part a lot of contractors gloss over until the crew is standing in your driveway with nowhere to work. We map that approval layer into the calendar before we ever give you a written price, so the timeline on page one is the timeline that actually happens. Call (803) 680-2547 for a free estimate, and we’ll walk you through what your specific street and HOA require.
Why Mason Remodeling Is Brentwood’s Preferred General Contractor Company
Brentwood homeowners aren’t comparing contractors on personality. They’re comparing who can name the actual approval steps for their specific subdivision, and who shows up with a price in writing before work starts. Mason Remodeling has done both since 2004, as part of the Threshold Group family of home-service companies. Every project starts with a written scope and written allowances, not a verbal ballpark that grows into a change order later. That matters in Brentwood, where picking a Cambria top over a builder-grade slab shouldn’t become a surprise invoice at week six.
Every crew member who walks through your door is identity-verified under the Threshold Standard: background-checked, in a clean marked uniform, with a photo ID badge at the door, and introduced to you by name and photo before the visit. You’ll know exactly who is coming. And our 365-Day Done Right Promise covers the workmanship for a full year from completion date – if something isn’t right, we make it right at no charge, including a free return visit. Isaac Pruett leads our Brentwood-area work, and our scheduling is coordinated from the brand’s San Francisco Bay Area office, with crews serving Brentwood locally.
Styles & brands we work with
Hire a General Contractor in Brentwood
Hire a General Contractor in Brentwood when the project touches structure, load, drainage, or anything an HOA or the City will inspect. That’s kitchens, baths, additions, garage conversions, and any exterior work that changes the visible face of the house. A general contractor in Brentwood carries the license, pulls the permits, schedules the inspections, and coordinates the trades – plumbing, electrical, tile, drywall, paint – so they land in the right order and pass final inspection the first time. Costs run from about $14,000 to $45,000 for a Brentwood kitchen remodel, $9,000 to $28,000 for a bath, and $45,000 to $130,000 for a home addition, with written allowances for cabinets, counters, and tile built in up front.
How We Scope a Brentwood Project
We start with the approvals, not the finishes. For homes in HOA-governed Brentwood subdivisions, that means reviewing the CC&R architectural review process first, because it gates the permit submittal. Then we build the written scope: demolition, rough-in, materials, finishes, inspections. Then we give you a written price with allowances stated plainly – what’s covered, what’s not, and what would change it.
What the Written Price Protects
Our written price is delivered before any work starts, on every project. Not as a favor, not as an upgrade. If you pick a Cambria quartz top instead of a builder-grade surface, the allowance math is already in front of you. That’s how Brentwood homeowners avoid the classic mid-job surprise: a change order for the exact stone, cabinet line, or fixture the design called for.
General Contractor Services in Brentwood
General Contractor Services in Brentwood cover the full build path: kitchen remodels, bathroom remodels, whole-home remodels, room additions, garage conversions, and deck construction. We also handle the trades that typically stall a Brentwood project – countertop installation runs $2,000 to $6,500, cabinet installation $4,000 to $13,000, and window replacement $4,500 to $15,000. Whether it’s a 1990s kitchen on the Balfour Road corridor or a garage conversion near Discovery Bay, the job gets scoped in writing before anything is ordered.
Kitchens and Baths
A Brentwood kitchen remodel at $14,000 to $45,000 usually includes cabinet install, countertop fabrication, plumbing rough-in for the sink and disposal, and finish electrical. Baths at $9,000 to $28,000 cover waterproofing, tile, vanity install, and shower build-out. We pull the City of Brentwood permits and pass final sign-off before you move back in.
Additions and Garage Conversions
Room additions in Brentwood start around $45,000 and run to $130,000, driven by foundation work, roof tie-in, and the HOA architectural review that governs any visible exterior change. Garage conversions at $30,000 to $80,000 come with their own structural and egress requirements, plus the same permit path. We handle both, including the inspection scheduling that keeps the calendar honest.

AfterCommon General Contractor Problems We See in Brentwood Homes
- HOA architectural review treated as an afterthought. In Brentwood’s planned subdivisions, exterior work like driveways, fences, and additions needs CC&R approval before the City permit can be filed. Contractors who assume the two run in parallel end up with a crew on-site and no approved permit.
- Subfloor and framing damage hiding under old flooring. We tore out a 1990s kitchen on the Balfour Road corridor where the original cabinets had swollen and the subfloor showed old water staining from a slow leak. In Brentwood’s aging 1990s and early-2000s stock, that hidden damage is common – and it changes the scope once you open the walls.
- Change orders the moment a homeowner picks a real material. Builder-grade allowances look cheap on the bid, then balloon when the homeowner picks Cambria over laminate. Our written allowances for cabinets, counters, and tile state the actual math before you choose.
- Punch lists that skip drywall and paint finish. Gaps, uncaulked edges, and rough trim get flagged – by the HOA, by the next buyer’s inspector, or both. Brentwood homes get finished to a standard that survives that second look.

FAQs About General Contractor in Brentwood
Yes, nearly always. The City of Brentwood requires permits for plumbing rough-in, electrical changes, and most structural work – even when you’re keeping walls where they are. A kitchen remodel that only swaps cabinets and counters may not need a structural permit, but any sink, disposal, lighting, or outlet work requires one. And if your home is in an HOA-governed subdivision, the architectural review may gate even non-structural exterior changes. Call (803) 680-2547 and we’ll tell you exactly what your address requires before anything is ordered.
In most Brentwood planned communities, the HOA CC&R review must be approved before the City permit can be submitted – they don’t run in parallel. That can add two to six weeks before the first shovel goes in, depending on the subdivision. A contractor who doesn’t account for this will schedule the crew early, then burn days waiting for paper. We build that gate into the calendar on page one, so the start date we give you is the date work actually begins.
The big three are hidden subfloor or framing damage, change orders for cabinets and counters beyond the written allowance, and scope changes once walls are open. In Brentwood’s 1990s and early-2000s housing stock, old water staining and swelling under the cabinets is common. Our written price states the allowance for materials in plain numbers, so you know the math before you pick a Cambria top or a custom cabinet line. Nothing surprises you mid-job – if a change is needed, it’s agreed in writing first.
A Brentwood kitchen remodel typically runs six to ten weeks from the first day of demo to final City inspection, assuming the HOA review and permits are already cleared. Bathrooms run four to seven weeks. Home additions and garage conversions run three to six months, driven by structural work, roof tie-in, and the inspection calendar. We give you a written schedule with the actual approval gates mapped, not a generic estimate. Call (803) 680-2547 for a free timeline specific to your project.
Yes. We install KraftMaid and Wellborn cabinetry, Cambria, Silestone, and Caesarstone surfaces, and Kohler, Moen, Toto, and Grohe fixtures. If your designer spec’d a particular line, we use that line – we don’t substitute a cheaper product to hold margin. We also know which materials hold up in Brentwood’s hot, dry summers and damp winters, and we’ll tell you if a specified product is a poor fit for your home before you spend money on it. Estimates are free at (803) 680-2547.
