Fast, Reliable General Contractor Across La Verne
Hiring a General Contractor in La Verne means finding someone who understands hillside soils, historic design review, and the wind loads that come off the San Gabriels. We’re Square One Builders, led by Brent Calloway, and we’ve managed full-scope remodels, additions, and ADUs across La Verne for years. Whether you’re restoring a 1920s bungalow off Bonita Avenue or adding a second story in the northern hills, we handle the structural work, finishes, and permit paperwork under one contract. Call (877) 688-9930 to schedule your free estimate.
Why Square One Builders Is La Verne’s Preferred General Contractor Company
We’ve earned repeat business in La Verne by doing the unglamorous work right: engineering hillside foundations on expansive clay, pulling historic-district design approvals, and matching 1940s trim profiles so an addition doesn’t read as an afterthought. Homeowners call us because we quote the job honestly the first time. That means a written line-item scope, a permit schedule, and no mid-project change orders unless you approve them in writing first.
Our La Verne customers consistently point to two things in reviews: we show up when we say we will, and the final trim looks like it was always there. When a job involves Old Town design guidelines, we handle the review process ourselves rather than asking you to figure it out. That’s the difference between a contractor who works in La Verne and one who actually knows it.
Response time to La Verne is straightforward: we schedule estimates within a week, and once permits are pulled, our crews work consecutive days until the rough inspections pass. No drifting between three other cities while your kitchen sits open.
Styles & brands we work with
Construction Company in La Verne
A Construction Company in La Verne takes on the structural and systems work most remodelers won’t touch: additions, ADUs, load-bearing wall changes, foundation repair, and full rough-in. If you’re adding square footage or converting a garage, that’s us. Home additions in La Verne run $45,000 – $130,000, and ADU construction typically falls between $90,000 and $220,000, depending on whether you build site-framed or go with a prefab partner like Abodu or Dvele.
Hillside Foundations and Retaining Walls
La Verne sits against the San Gabriels on expansive clay that moves with winter rains and summer drought. Any addition or ADU on a foothill parcel needs a soils report and, in most cases, an engineered foundation with retaining-wall design. We coordinate the geotechnical engineer, structural engineer, and city plan check so the foundation detail is approved before we ever break ground.
Garage Conversions and ADUs
A garage conversion in La Verne runs $30,000 – $80,000, and it’s often the most cost-effective way to add a rental unit or in-law suite. But the existing slab usually wasn’t poured to habitable-space standards, and the side walls may need shear reinforcement. We handle that scope under the same contract, which means one team accountable for the structural upgrade and the finished space. Brent Calloway has guided dozens of La Verne homeowners through the garage-conversion permit path, including the title 24 energy calcs and fire separation details the city requires.
Remodeling Contractor in La Verne
A Remodeling Contractor in La Verne handles whole-home updates, kitchen and bath work, and exterior re-skins without moving walls or pouring foundations. Kitchen remodels here run $14,000 – $45,000, while bathrooms typically land between $9,000 – $28,000. The wide range reflects what’s behind the walls: a 1950s bungalow with galvanized plumbing and knob-and-tube wiring will cost more to remodel than a 1970s tract home that’s already on copper and Romex. We quote the abatement and rough-in as visible line items, not buried allowances.
Kitchen and Bath Remodels
We spec cabinetry from KraftMaid or Wellborn, countertops from Cambria or Silestone (and can coordinate Silestone repair in La Verne if you’re keeping existing surfaces), and plumbing fixtures from Kohler, Moen, or Delta, depending on your budget tier. The point is one accountable team from demo to finish, so you’re not coordinating a plumber, an electrician, and a cabinet installer yourself. For older La Verne homes near downtown, we match trim and molding profiles to the original house so the new kitchen doesn’t look grafted on.
Whole-Home Renovation and Exterior Systems
Whole-home updates in La Verne often mean dealing with multiple systems at once: roofing, windows, siding, and hardscape. That’s exactly where a single-contract approach pays off. We can re-roof with GAF or CertainTeed, install impact-rated PGT windows, and re-side with James Hardie fiber cement, all sequenced so the exterior work closes up before the interior finishes start. No seams between trades because there aren’t any.
Trusted Brands We Service in La Verne
Our clients regularly choose CertainTeed and Owens Corning for roofing on La Verne homes, especially where Santa Ana winds put a premium on rated ridge caps and nail patterns. The GAF Timberline line also appears often on the 1960s tract homes in the northern hills. Because we order local and keep tight relationships with our suppliers, La Verne customers aren’t waiting an extra week for a roof underlayment or a matching shingle bundle to ship in. We stock what this market actually needs, and we install per the manufacturer’s written wind-rating so the warranty stays intact.

AfterCommon General Contractor Problems We See in La Verne Homes
- Expansive clay movement under older foundations. Winter rains soak the hillside soils, then summer heat dries them out, and the footing moves. We see cracked stem walls, stuck doors, and hairline wall cracks in the 1920s – 1950s stock near Old Town more than anywhere else in the area.
- Santa Ana wind damage to roofs and windows. Gusts off the San Gabriels tear loose shingles that weren’t nailed to the manufacturer’s high-wind pattern. Impact-rated window retrofits are becoming standard on hillside properties for both wind and ember protection.
- Historic-district trim mismatches. A remodel near Bonita Avenue needs period-correct casing, eave details, and porch elements. We’ve seen additions pass structural review only to stall at design review because the window trim was a stock modern profile.
- Hillside drainage problems undermining subfloors and decks. A 1948 bungalow we worked on had a cupped subfloor from a hillside drainage channel that had been buried decades earlier. The deck ledger was fine; the water path wasn’t. We re-routed the drainage before rebuilding, which is the kind of thing that only shows up once you open the floor.
Pricing for General Contractor in La Verne, CA
Here’s what a general contractor scope in La Verne actually costs, based on our recent bids and completed work in the 91750 ZIP code:
| Project | Typical Range in La Verne |
|---|---|
| Impact Window Installation | $8,000 – $25,000 |
| Roof Replacement | $8,000 – $20,000 |
| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
What moves these numbers in La Verne specifically? Hillside foundations add engineered design and retaining-wall scope. Wind-load-rated roofing and impact windows cost more than standard products but are increasingly required to pass inspection and keep insurance carriers satisfied. Historic-district material matching on an Old Town remodel adds custom millwork time. We give you a written, line-item quote with allowances spelled out, and the price doesn’t change unless you approve a change order in writing first. Call (877) 688-9930 for your free estimate.

FAQs About General Contractor in La Verne
Yes. Most exterior work visible from the street within the Old Town La Verne Historic District requires design review before the building permit is issued, which means matching roof pitch, eave detail, window trim, porch elements, and exterior materials to the original era. We prepare the design review submittal and attend the hearing or administrative review with you. Call (877) 688-9930 and we’ll walk you through which parts of your project trigger review and which don’t.
Wind-load rating determines the nail pattern, shingle type, and underlayment required for a roof, and the frame attachment and glass rating for windows. In La Verne, homes above the foothill streets face stronger Santa Ana gusts than the flatlands, so a compliant quote includes the manufacturer’s high-wind installation details and a fastener schedule the inspector can verify. Cheap bids often skip the supplemental fasteners or use a standard wind zone, and that’s what voids a warranty and gives an insurance carrier a reason to deny a claim later.
Because the expansive clay slopes at the base of the San Gabriels move seasonally, and a standard prescriptive footing detail doesn’t account for that movement. An engineered foundation includes a soils report, slope-stability review, and pier or retaining-wall design that keeps the addition or ADU stable through wet winters and hot, dry summers. Flatland tract cities like Claremont or Pomona rarely trigger the same requirement, which is why a contractor who only works those cities may miss it entirely.
At minimum: a line-item scope of work, a permit schedule with named inspections, written allowances for finish materials, the soils and structural engineering scope if your parcel is on a hillside, any required historic-district review, and an abatement plan if the house predates 1978. If a bid is a single number on a one-pager and your house is pre-1960, the surprises are already built in. We quote every line, including the change-order process you control, before you sign anything.
We test before we demo. Homes built before 1978 commonly have lead paint, and many 1920s – 1950s La Verne bungalows also have asbestos in old flooring, siding, or duct wrap. Our crews follow certified abatement procedures, contain the work area, and pull the required notifications. We handle it as a visible line item in your quote so there’s a paper trail for your lender and insurer, not a mid-job discovery that stops the project.
If you’re planning a remodel, addition, or ADU in La Verne, call (877) 688-9930 to schedule your free estimate.
