We answer our own phone at (877) 610-1318, and when you call about a project on Camino Pablo or Rheem Boulevard, the person on the other end knows exactly which hillside you mean.

Why Moraga Homeowners Choose Barrett & Sons Construction
Most of our Moraga customers come to us after a bad experience with a company that quoted one number on the phone and handed over a different invoice at the end. That doesn’t happen with us. Every scope of work, every material allowance, every change order arrives in writing before a single nail moves. Tom Barrett publishes his name, his address, and his license number; he wants you to look them up before you sign anything. The permit inspector works for you, not for me, Tom says, and that’s exactly why he likes having one on every eligible job.
We’ve worked extensively in the Sanders Ranch and Camino Pablo neighborhoods, and those jobs have taught us what Moraga construction actually demands. The hillside retaining walls off Sanders Drive, the older ranch homes on Donald Drive with original post-and-pier foundations, the 1970s split-levels that were never retrofitted; we’ve opened those crawl spaces and we know what’s underneath them. Our crews are background-checked, uniformed, and they carry the Barrett & Sons name because they’ve earned it. A live person answers our phone 24/7, so when you call at 7 a.m. on a Tuesday, you get us, not a voicemail.
Construction Services We Offer in Moraga
Kitchen Remodeling
Moraga kitchens from the 1960s and 70s were built small, often with the original layout still intact. We open them up, replace old electrical, and install brands you can look up, like KraftMaid cabinetry and Cambria countertops, with permits pulled and inspections signed.
Learn more about our Kitchen Remodeling in Moraga.
Bathroom Remodeling
Older Moraga bathrooms frequently hide rot behind original tile and failing wax rings. We gut them properly, correct the framing and moisture issues, and build bathrooms that stay dry for decades, with written change orders covering every allowance.

Roofing
Because Moraga sits inside a Very High Fire Hazard Severity Zone, roof replacement here isn’t optional about materials; it’s a code compliance issue. We install Class A fire-rated assemblies from GAF and CertainTeed that meet Chapter 7A WUI requirements and pass local inspection the first time.

Windows & Doors
Moraga’s temperature swings, with summer highs over 100°F and winter nights below freezing, punish cheap window frames. We install Andersen and Marvin products sized to your openings and flashed for our fire-zone code, not just caulked and left.
Fence Installation
Hillside fencing on expansive clay means posts set deep and adjacent drainage planned carefully, or the whole line moves within two seasons. We build fences that stay straight on Moraga slopes, using Belgard and Techo-Bloc products for hardscape tie-ins.
Driveway & Pavers
Steep Moraga driveways with bad drainage crack and heave quickly when water sits under the base. We grade first, then install pavers on a compacted, draining foundation built for the specific pitch of your lot.
Home Additions & ADU
Adding square footage in Moraga means engineered foundations for expansive clay, fire-rated exterior assemblies, and a permitted process from day one. We handle every trade, every inspection, and every piece of paper, so your ADU or addition finishes with a signed-off permit record.
Neighborhoods We Serve in Moraga
Our crews work throughout Moraga, and we typically reach most jobs within the same week of the estimate. The neighborhoods we’re in most often:
- Sanders Ranch - hillside homes with retaining wall and foundation needs
- Camino Pablo - original 1960s-70s ranch and split-level housing stock
- Rheem Valley - mid-century homes with original electrical and roofing
- Moraga Country Club area - custom homes and ADU projects
- Canyon Road corridor - steep lots with drainage and grading requirements
Why Moraga’s Climate & Housing Affect Construction
Moraga doesn’t build like the flatland cities over the hill. The town sits inside a sheltered inland valley where summer afternoons on west-facing rooflines top 100°F while winter nights drop below freezing. That thermal swing works wood framing, cracks caulk, and shortens the life of exterior paint faster than most Bay Area contractors expect. Then there’s the clay. The Montmorillonite-rich soil under Moraga’s hills soaks up winter rain and swells, then shrinks hard through the dry season. Under a 1960s ranch with an untouched post-and-pier foundation, that repeated movement translates directly into differential settlement, rotted sill plates, and sagged beams. We open those crawl spaces and it’s almost always there on pre-1980 houses.
And then there’s the fire code. Moraga lies entirely within a State-designated Very High Fire Hazard Severity Zone, so virtually every exterior project; new roofs, additions, ADUs, deck replacements; must comply with Chapter 7A WUI building standards. That means fire-rated roofing assemblies, multi-pane windows, enclosed ember-resistant eaves, and ignition-resistant siding. It’s not a suggestion. It’s not optional paperwork. It’s the law, and it adds real cost and real complexity to construction in Moraga that a Walnut Creek contractor may never mention until the inspector shows up. We build to it from the first estimate.
Pricing for Construction in Moraga
Construction costs in Moraga run above Bay Area flatland averages because of the fire-zone material requirements, the hillside engineering, and the clay-soil foundation work nearly every older home eventually needs. As a realistic starting point: full kitchen remodels in Moraga generally run $55,000 to $110,000. Bathrooms typically land between $25,000 and $55,000. Fire-rated roof replacement on a standard ranch runs $18,000 to $35,000, and a permitted ADU addition starts around $250,000 and climbs with site grading. These are honest ranges, not phone quotes. Every job gets a written, line-item estimate before any contract is signed.
| Project Type | Moraga Starting Range |
|---|---|
| Kitchen Remodel | $55,000 - $110,000 |
| Bathroom Remodel | $25,000 - $55,000 |
| Fire-Rated Roof Replacement | $18,000 - $35,000 |
| ADU / Home Addition | $250,000+ (site-dependent) |
| Driveway & Paver Work | $12,000 - $30,000 |
One thing worth knowing upfront: our price changes never show up as surprises at the end. If a scope item shifts, you receive a written change order with the new number on it before the work proceeds. An allowance that isn’t on paper is a surprise waiting for a date, and we don’t build that way.

FAQs About Construction in Moraga
Most Moraga kitchen remodels run between $55,000 and $110,000 depending on size, layout changes, and material selections. Fire-zone electrical upgrades and older-home framing corrections tend to push costs toward the upper end. Call (877) 610-1318 for a free written estimate specific to your house.
Moraga’s Very High Fire Hazard Severity Zone designation requires Chapter 7A WUI-compliant materials on exterior work, and the town’s steep clay hills demand engineered foundations, retaining walls, and graded drainage that flatland cities don’t need. Those aren’t optional upgrades; they’re code requirements that add real cost.
Yes. We pull permits and the inspections get signed on every eligible job. The permit inspector works for you, not for the contractor, which is exactly why we insist on having one involved. If a contractor tells you permits are optional in Moraga, walk away.
Only if the scope changes, and only after you receive a written change order with the new number on it before any additional work begins. We do not hand you surprise invoices at the end. That’s the rule, not the exception. Call (877) 610-1318 and we’ll walk you through how our written allowance process works.
Yes, and frankly we’d rather you not hire anyone who says they’ll skip them. Every roof, addition, ADU, and exterior remodel we build in Moraga meets Chapter 7A WUI standards, with fire-rated assemblies and multi-pane windows, and every inspection gets signed off before we call the job done.

What Moraga Customers Say
"Tom Barrett was on our job most days himself, not just at the quote and then never again. When something needed deciding there was an actual person to decide it with."
- Rosalie Pemberton"Came back a year later to sort a door that had dropped as the frame settled. No charge and no argument about whether it was covered."
- Thaddeus Oyelowo"Addition over the garage matched the original roofline and brickwork so closely that visitors do not realise it was added. He tracked down the closest brick he could find rather than settling."
