Styles & brands we work with







Construction Company in Lomita
Construction Company work in Lomita means something different than it does in Torrance or Carson. Lomita sits on a patchwork of pre-1950 and early postwar tract housing where many original garages were converted without permits. Before we can price a remodel, we often have to verify whether existing “living space” was legally converted. That single step changes scope, permitting, and cost. Unlike neighboring cities with more uniform housing stock, Lomita’s mix of tiny bungalows and later tract homes means no two jobs start from the same baseline.
Scoping the Job Correctly
A room addition in Lomita typically runs $45,000 – $130,000 depending on square footage, foundation requirements, and whether the existing structure can carry the load. A garage conversion runs $30,000 – $80,000. When we scope, we check what’s permitted, what’s original framing, and what was altered decades ago.
Pulling the Right Permits
In Lomita, unpermitted work from past owners catches up when you sell. We pull permits before any structural work starts, coordinate inspections with the city, and get sign-off before we call the job done. That protects you, not just your house.
Remodeling Contractor in Lomita

Remodeling Contractor work in Lomita looks different on a 1940s bungalow than it does on a 1960s tract home. On a recent bathroom remodel near Narbonne Avenue and 253rd Street, we opened up a wall and found no load-bearing header, just framing that had been altered years earlier with no permits on file. We pulled the right permits, added a properly sized load-bearing beam, and finished the job with a Kohler sink and tile that passed inspection on the first visit.
Material Selection That Holds Its Price
A countertop allowance that says “granite” or “quartz” without a brand attached can balloon once you pick a real slab. We write Cambria, Silestone, Caesarstone, KraftMaid, and Wellborn into the price up front. You know what you’re getting before we order it.
The Subfloor Question
Older Lomita homes have subfloors that have been patched, leveled, or ignored for sixty years. If we skip a proper subfloor inspection and leveling step on a pre-1950 home, you get cracked tile and uneven flooring six months later. We check first. It costs less than replacing a floor.
Trusted Brands We Service in Lomita
Lomita homeowners ask us about panelized and prefabricated systems, and we work with Abodu and Cover on ADU projects where the lot and zoning allow. We also service existing installations and handle repairs across vetted material lines including Cambria, Silestone, Kohler, Moen, and KraftMaid. Having specification-grade materials on hand means faster turnaround for Lomita customers, because we’re not waiting on out-of-area orders. Isaac Pruett, who leads Mason Remodeling, insists on materials we can stand behind for the full 365 days.

AfterCommon General Contractor Problems We See in Lomita Homes
- Unpermitted garage conversions. Lomita has a high number of postwar homes with garages turned into living space without city permits. Before we quote any remodel that touches that space, we check what’s legal. It changes the scope, the budget, and sometimes the whole plan.
- Altered load-bearing framing. In pre-1950 bungalows around Lomita, we regularly find walls opened up by past owners with no header and no permit on file. That’s a safety issue and a code issue. We fix it correctly before building anything new.
- Vague material allowances. A quoted price that says “quartz countertops” with no brand lets the final bill drift upward once you pick a specific slab. We write Cambria or Silestone into the line item. Fixed price, no drift.
- Skipped subfloor leveling. Older foundations settle unevenly across Lomita. If a contractor lays tile on an unleveled subfloor, cracks show up within a year. We level first, then install. It’s cheaper than doing it twice.

FAQs About General Contractor in Lomita
Yes, if you’re changing plumbing, electrical, or structural elements, Lomita requires permits. Moving a sink, adding circuits, or removing a load-bearing wall all trigger permit requirements. If we find prior unpermitted work, we include the cost of bringing it to code in your written estimate. Call (803) 680-2547 and we’ll check your specific project before you spend a dollar.
A standard bathroom remodel in Lomita takes two to four weeks from demo to final inspection, depending on scope, material lead times, and whether we discover framing or subfloor issues in older homes. Pre-1950 bungalows often add a few days for structural corrections. We give you a calendar in writing before we start.
A small kitchen remodel in Lomita runs $9,000 – $20,000. That covers cabinet replacement, countertop installation, a new sink, and basic plumbing and electrical work, assuming no structural surprises. If the demo exposes unpermitted framing changes or sink plumbing that was installed without a permit, the price moves up. We write the allowance into the estimate so you see it coming. Call (803) 680-2547 for an exact quote.
