Fast, Reliable General Contractor Across Laguna Hills
Most renovation work in Laguna Hills starts with one discovery: the house was built in the 1970s or 80s, and what’s behind the stucco was never meant to last this long. That’s exactly where a full-scope General Contractor earns the fee. We’re a licensed general contractor led by Brent Calloway, and we’ve worked on enough tract homes and townhomes across 92653 and 92654 to know what opens up when the walls come down. You get one team accountable for every system, from the roof to the pavers, with a number you can call: (877) 688-9930.
Why Square One Builders Is Laguna Hills’s Preferred General Contractor Company
Laguna Hills is not a city where you build from scratch. You remodel, you add on, you rebuild. We understand that on most streets around Moulton Ranch and Nellie Gail Ranch, the original framing, wiring, and waterproofing are now 30 to 50 years old, and a permit opening the wall changes the scope. Homeowners here tell us they value straight answers and a single accountable team, which is why our estimate process includes an early inspection conversation and written allowances for the issues we know to expect on this housing stock. Our reputation in Laguna Hills is built on showing up, documenting what we find, and pricing the fix before we touch it.
We serve the full General Contractor in Laguna Hills market from Westminster without running three-trade chaos on your job. When a Laguna Hills homeowner calls, they speak with a team that already knows the local permit office’s position on hillside grading, the way expansive clay soils behave on cut-and-fill pads, and what a 1978 Mediterranean-style tract house looks like behind the drywall. That local fluency shortens the time between your first call and a real written scope.
Styles & brands we work with
Residential General Contractor in Laguna Hills
Residential General Contractor work in Laguna Hills is rarely a clean slate. It is a 1974 stucco original in Moulton Ranch with aluminum branch wiring, a low-pitch tile roof now at the end of its service life, and a kitchen somebody “updated” in 1998. The job starts with figuring out what you actually own. We walk the house, pull the permit history where it exists, and look at the foundation, the roof-to-wall connections, and the electrical panel before any number goes in front of you. A full kitchen remodel in Laguna Hills typically runs $14,000 – $45,000, while a bathroom remodel lands between $9,000 and $28,000. Those ranges reflect the reality of mature housing stock, not just cabinet selection.
Remodel Scoping With Written Allowances
We scope remodels with line-item allowances for the things we cannot see until the wall is open. On a Laguna Hills tract home, that usually means a wiring allowance, a framing repair allowance, and a waterproofing allowance. You see every one of those numbers before we sign, and no surprise gets billed without a written change order and your approval.
Additions and Second Stories on Sloped Lots
Adding square footage in Laguna Hills means working with the city on setbacks, grading, and structural review, especially on slope-side parcels east of Moulton Parkway. A home addition here typically runs $45,000 – $130,000, and we plan the foundation work around the cut-and-fill pads that dominate this valley.
Hire a General Contractor in Laguna Hills
When you hire a General Contractor in Laguna Hills, you are hiring the person who owns the permit, the schedule, and the trade coordination. That matters more here than in newer cities, because the surprises are structural. We pull permits for load-bearing work, schedule the inspections, and stand behind what gets covered up. If you are planning a shower replacement or a kitchen island install, a bathroom remodeling project here runs $9,000 – $28,000; a small bathroom remodel runs $5,000 – $12,000. The point is not the lowest quote. It is a quote that survives contact with the walls.
Single Contract, Every System
From the ground up, one contractor, every system. Roofing, windows, cabinets, plumbing fixtures, hardscape, and the ADU in the back corner all sit under one contract, which means one throat to choke when something needs fixing. We spec the right material for your project, whether that means James Hardie siding on a wind-exposed hill or a Class A GAF roof for fire season.
Permit-Ready Paperwork Before Demolition Day
We do not open a load-bearing wall in Laguna Hills without a permit and an inspection path. The city review process here is straightforward but detailed, and we handle the drawings, the engineering, and the sign-offs so you never sit with an open wall and a stop-work order.
Trusted Brands We Service in Laguna Hills
We install and stand behind material systems homeowners in Laguna Hills ask for by name. On the roofing side, we work with GAF, CertainTeed, and Owens Corning, three of the largest U.S. manufacturers, which matters when you are replacing a 30-year-old tile roof on a stucco tract house where Class A fire rating is a real selling point. On windows, we spec PGT and Therma-Tru for their wind and heat performance in our inland summer climate. We do not push one brand. We match the material to the project, the exposure, and your budget, and we can quote multiple tiers within the same category, like GAF versus Tamko on a roof, without switching contractors.
Common General Contractor Problems We See in Laguna Hills Homes
- Aluminum branch wiring from the 1970s. Once a permit opens a kitchen or bathroom wall in a Moulton Ranch original, the inspector will often require remediation. We budget for this before you sign.
- Failed waterproofing behind original stucco. Decades of UV and heat cycling crack the exterior skin and let water sit against the framing. We find it on nearly every exterior-facing wall we open.
- Settlement on cut-and-fill pads. On the slope-side lots above Laguna Hills and around Nellie Gail Ranch, expansive clay soils move the original 1970s and 80s retaining walls and foundations.
- Undersized framing from fast tract builds. Original builders used the minimum lumber they could get away with. When we remove a wall for an open kitchen, the beam and footing work is almost always bigger than the homeowner expected.

FAQs About General Contractor in Laguna Hills
A quote changes because a 1970s or 80s tract home hides aluminum wiring, undersized framing, and failed waterproofing that only a permit opening reveals. We handle that by writing allowances into the contract before demolition, so you see the likely cost range upfront. Any change above allowance is documented and approved in writing before we proceed. Call (877) 688-9930 to get a quote built for what your house actually contains.
Yes. The city requires permits and inspections for any load-bearing wall removal, and we will not open one without a permit in place. We handle the drawings, the beam sizing, and the inspection scheduling. Skipping this step on a remodeling job saves money for about a week and costs you in title trouble, failed inspections, and safety down the road.
We treat the foundation and retaining walls as part of the scope before a single interior wall comes down. On the cut-and-fill slope lots around Nellie Gail Ranch, expansive clay has already moved many original 1970s foundations, and the city reviews hillside grading and drainage with extra scrutiny. We bring in a geotechnical engineer when the existing conditions warrant it and write the foundation repair into the contract as a defined line item, not a surprise change order. Call (877) 688-9930 for an exact scope on your hillside lot.
You should have a line-item contract that lists the scope, the allowances for concealed conditions, the payment schedule tied to inspection milestones, and the written change-order process. Every one of our Laguna Hills contracts includes those four things. If a contractor will not write the allowance structure into the contract, that is the first red flag. Estimates are free, so call (877) 688-9930 and ask to see ours.
Yes, and most of our larger Laguna Hills projects are exactly that: additions and partial second stories engineered around existing slab-on-grade foundations and tight setbacks. A home addition here runs $45,000 – $130,000, and a full ADU construction runs $90,000 – $220,000. The structural question is always the same: can the existing pad and framing take the load, and what does the city require to prove it. We answer both before we quote.
