Why Mason Remodeling Is La Mirada’s Preferred General Contractor Company

That matters when you’re home alone, or when your kids are home with you while work is underway.

The price you sign is the price we build to, and every project carries a written guarantee with clear terms.

Styles & brands we work with
General Contractor Services in La Mirada
General Contractor Services in La Mirada typically involve remodeling and adding to existing homes rather than building from scratch, because the city is largely built out. A full kitchen remodel runs $14,000 – $45,000, and a bathroom remodel falls between $9,000 and $28,000. Home additions range from $45,000 to $130,000 depending on foundation, framing, and utility work. Every project starts with a written scope and a fixed price.
Remodeling Existing Mid-Century Homes
Most La Mirada work happens inside 1950s and 1960s tract houses. That means selective demolition before final pricing: we open a wall to see the framing, check the panel capacity, and confirm joist sizing before we lock numbers. This prevents mid-project change orders that blow up your budget.
Permits and Inspections
We pull permits for structural work, electrical, plumbing, and additions through the City of La Mirada. Skipping permits on a garage conversion or ADU can surface at resale and kill a deal. We handle the paperwork, schedule inspections, and close out with sign-off in hand.

Construction Company in La Mirada
As a Construction Company working in La Mirada, we coordinate the full build: demolition, rough-in, finishes, and inspection. Room additions on the city’s standard 5,000 to 7,000-square-foot lots typically run $45,000 – $130,000. ADU construction starts around $90,000 and can reach $220,000 for a detached unit with full utility runs. Garage conversions are the most budget-friendly path at $30,000 – $80,000, and they make practical sense on lots where a detached ADU would eat too much yard.
Building to La Mirada’s Setbacks and Codes
La Mirada’s zoning rules govern how close you can build to property lines, how tall an ADU can rise, and where the parking has to land. We handle the site plan and variance path if needed, so your project doesn’t stall at plan check. Buyers and refinancers check for unpermitted work, and an ADU with no permits is a liability, not an asset.
Working With Your Home’s Bones
On a 1960s tract house off Biola Avenue near the university, our crew stripped a galley kitchen to the studs and found the original 1959 subfloor had been sistered twice and the main panel was still a 100-amp service. We pulled the permits, upgraded the rough-in and load-bearing header over the old pass-through, set KraftMaid cabinets with a Cambria quartz top, and closed it out with a written punch list before final inspection sign-off.
Trusted Brands We Service in La Mirada
Whenever a La Mirada homeowner has a product preference, we install it correctly rather than urging a brand swap. We spec KraftMaid and Wellborn cabinetry, Cambria and Caesarstone surfaces, and Kohler or Moen fixtures. We also work with modern prefab partners like Abodu and Dvele when a pre-engineered ADU fits the lot better than stick-built construction. Because we stock common parts locally, we avoid the week-long waits that plague projects ordered through big-box channels.

AfterCommon General Contractor Problems We See in La Mirada Homes
- Original 1950s – 60s plaster walls hiding structural surprises. You can’t see a sagging header or a termite-damaged sill plate behind lath and plaster. Bidding a fixed price from photos, without opening a wall, is how La Mirada remodels blow past the draw schedule.
- Undersized 100-amp electrical panels. A kitchen remodel that adds a double oven, induction cooktop, or EV charger often needs a panel upgrade. If the quote doesn’t include it, that’s a $3,000 – $5,000 surprise mid-project.
- Unpermitted additions and garage conversions. Owners who wanted to “keep it simple” now can’t refinance or sell without retroactive permits. The City of La Mirada will require the work be brought to current code, which costs more than permitting correctly from day one.
- Allowance games on cabinetry and finishes. Treating cabinet, countertop, and fixture allowances as loose verbal numbers means selections land 20 – 30% over budget. We put every allowance in writing with exact dollar caps before work starts.

FAQs About General Contractor in La Mirada
Yes, if you’re moving walls, altering plumbing or electrical, or changing the structure. A cosmetic refresh like paint and cabinet refacing doesn’t require one, but any La Mirada remodel that touches framing, panel capacity, or drain lines does. We pull the permits and manage inspections so the work is legal and saleable. Call (803) 680-2547 to confirm your project’s permit path.
Because most La Mirada homes were built in the 1950s and 1960s, and the original condition behind the walls is rarely what the photos show. A cheap first estimate often skips panel upgrades, subfloor repair, and load-bearing header work. Our written price includes the selective demolition we need to lock the real number. Call (803) 680-2547 for a quote that won’t drift.
A bathroom remodel runs 3 to 6 weeks, a kitchen 6 to 10 weeks, and an addition or ADU can take 4 to 8 months including plan check and inspections. La Mirada’s permit review times vary by project type, and we calendar your project around that reality rather than promising a date we can’t hold. Call (803) 680-2547 to get a realistic schedule for your scope.
Yes. Garage conversions in La Mirada run $30,000 – $80,000 and are the most economical ADU path, since the structure already exists. You’ll need electrical, plumbing, insulation, and a separate entrance to meet California ADU code. We handle the design, permits, and build. Call (803) 680-2547 to see if your garage qualifies.
At minimum: a fixed price, a scope of work listing every task and material allowance, the permit list, a draw schedule tied to milestones, and the written guarantee terms including duration and what’s excluded. We provide all of it before any tool touches your La Mirada home. Call (803) 680-2547 to start that paperwork today.
