AfterConstruction Services in Belmont, CA
Belmont sits in a tight pocket between Highway 101 and the Santa Cruz Mountain foothills, and the homes here reflect that squeeze: hillside ranches on cut-and-fill pads, split-levels tucked against steep grades, and a handful of older Craftsman-era cottages down near the Caltrain corridor. We know these houses because we work on them every week. If you’re planning a remodel, an addition, or a roof replacement in Belmont, call us at (877) 610-1318 and you’ll get a live person, not a voicemail. We’ll talk through what you’re considering, what the city will want to see, and whether your project needs a soils report before anything else moves.

Why Belmont Homeowners Choose Barrett & Sons Construction
Barrett & Sons is owner-operated, with Tom Barrett’s name on the truck and his sons running the crews. When a homeowner in the Hallmark Drive hills or over near Ralston Avenue calls us, they’re not getting a franchise that dispatches strangers. They get the same crew lead on day one and day thirty. That matters on hillside work, where the person reading the soil conditions and checking the retaining wall needs to remember what the lot looked like before the excavation started.
We’ve built our Belmont reputation one job at a time: kitchens and baths in the ranch homes above El Camino Real, roof replacements on homes where winter rain hits harder than it does down by the bay, and additions that required geotechnical review before the city would even look at the plans. Our standing offer to Belmont homeowners is simple: a free second opinion on any written estimate you’ve received, no trip charge inside the county, and $40 off any repair over $200. Tom publishes his name, address, and license number. Look them up before you sign anything.
Construction Services We Offer in Belmont
Kitchen Remodeling
Belmont kitchens tend to be compact, and the best remodels in this city are about working with the existing footprint rather than blowing out walls on a hillside lot. We plan cabinet layouts around the quirks of 1950s and 1960s framing, and we specify materials like KraftMaid and Cambria so you know exactly what’s going in.
Learn more about our Kitchen Remodeling in Belmont.
Bathroom Remodeling
Older Belmont homes often have original cast-iron drain lines and bathrooms that were never designed for modern ventilation. We address the plumbing and moisture issues first, then build out the bath with Schluter waterproofing systems and fixtures from Grohe and Sterling, depending on your budget and style.

Roofing
Belmont’s winter rainfall is noticeably heavier than what bayfront cities get, and sloped lots mean water flows toward foundations, not away from them. We install GAF roofing systems with the underlayment and flashing details that hold up to saturated clay soils and the occasional wind-driven storm off the foothills.
Learn more about our Roofing in Belmont.
Windows & Doors
Marine fog and cool summer air mean condensation control and proper flashing matter more in Belmont than in inland Peninsula cities. We replace windows and doors with Andersen and Marvin products sized to the original openings, so you don’t end up with stucco patches that never match.

Fence Installation
Belmont’s hillside lots create fence challenges you won’t find on flat ground: grade changes, retaining wall tie-ins, and posts set into expansive clay that shifts every rainy season. We handle the grading and drainage considerations before the first post goes in.
Learn more about our fence installation in Belmont.
Driveway & Pavers
Steep driveways are common in Belmont’s hill neighborhoods, and poor drainage is the usual cause of cracked concrete and sinking pavers. We install Belgard and Techo-Bloc hardscape systems with base preparation that accounts for clay soil movement, so the surface doesn’t shift after one wet winter.
Learn more about our driveway and paver services in Belmont.
Home Additions & ADU
Adding square footage in Belmont usually means building into a slope, which triggers geotechnical review and soils reports before permits are issued. We’ve navigated that process enough times to budget for it honestly and schedule it realistically, so the project doesn’t stall at plan check.

Why Belmont’s Climate & Housing Affect Construction
Belmont’s residential construction landscape is defined by its steep hillside neighborhoods, where postwar developers used cut-and-fill grading to carve lots into the Peninsula’s clay-heavy foothills. That means a disproportionate share of projects here involve retaining walls, drainage remediation, and foundation work on lots where the fill portion has been settling for 50 to 70 years. Unlike flatter neighbors like San Mateo or Foster City, nearly every significant construction project in Belmont’s hill neighborhoods triggers geotechnical review requirements before the city will issue permits.
The building department requires a soils report for most additions or ADUs on hillside lots. That’s a step many contractors from flatland Peninsula cities aren’t budgeted or prepared for, and it can add weeks to the permit timeline. Belmont also gets more winter rainfall than bayfront cities to the east, which saturates the Franciscan clay soils on sloped lots and accelerates soil creep, retaining wall failure, and drainage system stress every rainy season. Summer fog slows exterior finish curing, so stucco, painting, and concrete flatwork need to be scheduled carefully. These aren’t abstract concerns for us. They’re the reason we walk every Belmont lot before we quote it.
Pricing for Construction in Belmont
Belmont construction costs run above the regional average because of the hillside factor: engineering, soils reports, drainage remediation, and retaining work all add line items that don’t exist on flat lots. Here are honest starting ranges based on the work we’ve completed in 94002:
- Kitchen remodel: $45,000-$90,000, depending on layout changes and finish level
- Bathroom remodel: $25,000-$55,000, including waterproofing and plumbing updates
- Roof replacement: $18,000-$38,000, depending on roof slope and decking condition
- Window replacement (full house): $15,000-$35,000
- ADU or addition (hillside): $350-$550 per square foot, including geotechnical and permit costs

FAQs About Construction in Belmont
A kitchen remodel in Belmont typically runs $45,000 to $90,000, with hillside homes on cut-and-fill lots sometimes adding $5,000 to $15,000 for structural and drainage work before finishes are even considered. The range depends on whether you’re keeping the existing footprint or moving walls, and on the cabinet and countertop brands you select. We install KraftMaid and Cambria regularly, but we’ll quote whatever you’re comfortable with. Call (877) 610-1318 for a written estimate specific to your home.
Only if the scope changes, and only after you sign a written change order approving the new number. Every allowance and every scope item is in writing before the first day of work. If we discover something unexpected, like a failed retaining wall or settled fill under the foundation, we’ll show you what we found, explain the options, and put the revised price on paper before we proceed. No surprise invoices at the end.
Most additions and ADUs on Belmont hillside lots require a soils report and geotechnical review before the city will issue permits. The building department has mapped active landslide deposit zones in parts of the city, and those zones add geologic review time to the permit process. We handle that paperwork for you, and we budget for it honestly up front. If you’ve gotten an estimate from a contractor who didn’t mention a soils report for a hillside addition, call us at (877) 610-1318 for a free second opinion.
Yes, on every eligible job. Permits are pulled and inspections are signed before we call the project complete. The permit inspector works for you, not for me, and that’s exactly why I like having them involved. If a contractor tells you permits are optional in Belmont, walk away and call us instead.
A kitchen or bath remodel in Belmont typically takes 6 to 12 weeks once permits are issued. A hillside addition or ADU usually runs 4 to 8 months, with a meaningful portion of that time spent on geotechnical review, plan check, and foundation work before framing begins. We’ll give you a written schedule before we start, and we’ll keep you updated on any changes. Call (877) 610-1318 to talk through your project timeline.
