Fast, Reliable General Contractor Across South Gate
Most South Gate homeowners call us after they’ve already tried to piece together a remodel with separate subs, or after a handyman quote fell apart. We’re Mason Remodeling, and we’ve spent two decades as a General Contractor handling kitchens, baths, additions, and whole-home work in neighborhoods like Tweedy Mile, Stanford-Avalon, and Hollydale. If you live in South Gate, you know the lots are tight, the houses are older, and the permit history isn’t always clean. That’s exactly what we scope for. Call (803) 680-2547 and we’ll walk your project before we quote it.
Why Mason Remodeling Is South Gate’s Preferred General Contractor Company

South Gate homes were mostly built between 1920 and 1955, and they carry the quirks of that era: stucco exteriors, shallow foundations, narrow side yards, and floor plans that were designed for a different century. A contractor who only knows new construction will misread those houses. Our team has worked enough South Gate remodels to know what’s behind the walls before we open them, and we price accordingly.
When you schedule with us, you’ll know who is coming before they knock. Every crew member is background-checked and identity-verified under the Threshold Standard, and you receive their name and photo ahead of the visit. They arrive in a clean, marked uniform and show a photo ID badge at the door. That matters when you’re letting someone into your home in South Gate, especially if you’re home alone or have kids.
You’ll also get a written price before any work begins. Not a verbal ballpark. A written scope with allowances and a draw schedule. That’s been our standard since Mason Remodeling was founded in 2004 as part of the Threshold Group family, and it doesn’t change for South Gate jobs.
Styles & brands we work with







Licensed General Contractor in South Gate
A Licensed General Contractor in South Gate does more than swing a hammer. On narrow-lot homes along streets like California Avenue and Firestone Boulevard, the contractor’s real job is sequencing: knowing what the city will flag, what the inspector will look for, and what order the work has to happen in so you’re not paying for rework. In South Gate, a kitchen remodel typically runs $14,000 to $45,000, and the spread comes down to whether we’re moving load-bearing walls, upgrading electrical, or repairing a subfloor that’s been under tile since the Eisenhower administration.
Permit History and Site Survey First
South Gate has a lot of unpermitted work from past decades: enclosed patios, converted garages, rear additions that bumped into the property line. Our first step on any substantial job is pulling the permit history and walking the lot. If we find something that doesn’t match city records, we’ll tell you before we write the contract, because it changes the price and the calendar.
Written Scope, Allowances, and Draw Schedule
We don’t quote a flat number and hope for the best. Your South Gate project gets a line-item scope, a list of allowances for finishes, and a draw schedule tied to milestones, not to our cash flow. You’ll know what each phase costs and what triggers each payment before the first tool is unpacked.
Residential General Contractor in South Gate

A Residential General Contractor in South Gate handles the work that turns a cramped 1950s floor plan into a home that fits the way you actually live. That might mean opening the kitchen into the dining room, adding a primary suite, or converting a detached garage into an ADU. On lots that are 40 to 50 feet wide, the constraint is almost always the side-yard setback and the fire-separation requirements. That’s why we scope from the property line inward, not from the room outward.
Additions and ADUs on Narrow Lots
A home addition in South Gate runs $45,000 to $130,000, and an ADU construction project runs $90,000 to $220,000. The difference often isn’t square footage; it’s whether the existing foundation can carry the added load, whether the sewer lateral needs replacement, and whether the new structure triggers upgrades to the whole electrical service. We’ll tell you which of those apply before you commit.
Garage Conversions and Retroactive Permits
Garage conversions in South Gate run $30,000 to $80,000. Here’s the thing: a lot of South Gate garages were converted in the 1970s and 1980s without permits. If yours was, we don’t pretend it wasn’t. We scope the work so the permitted portion moves forward while the city processes the retroactive approval for what’s already there. It takes longer, but it protects the value of the house.
Trusted Brands We Service in South Gate
South Gate homeowners sometimes ask us about modular or panelized options, and we’re familiar with what’s out there: Abodu, Cover, and Mighty Buildings all make prefab ADU shells that can work on a South Gate lot if the site conditions line up. We’ll give you an honest read on whether a prefab path saves time and money on your specific property, or whether stick-built makes more sense. We also source specification-grade materials from brands like KraftMaid, Kohler, and GAF, and we keep standard-order lead times in mind when we build your schedule.

AfterCommon General Contractor Problems We See in South Gate Homes
- Unpermitted rear additions discovered mid-project. A homeowner near Tweedy Boulevard and Independence Avenue wanted a kitchen remodel and a garage conversion in the same 1950s stucco house. Our tech found a prior unpermitted rear addition that didn’t meet side-yard setbacks. We scoped the kitchen separately so the permitted work could move forward, pulled the permit and inspection sign-off for the addition before the garage conversion, and the homeowner got the kitchen done on schedule while the city approved the addition retroactively.
- Load-bearing walls hidden in small kitchens. South Gate’s narrow homes often used the wall between kitchen and living room as a structural support. Removing it means a beam, a footing check, and a structural engineer’s letter. That’s a real cost driver that a surface-level quote misses.
- Subfloor and framing rot under old tile. Homes built in the 1920s – 1950s along the Los Angeles River corridor used dimensional lumber that’s had 70-plus years to settle and swell. When we pull up old tile, we frequently find subfloor that needs repair before new flooring can go down.
- Electrical panels too small for modern loads. A 1950s South Gate home was built for a 60-amp service. Adding a kitchen island with outlets, a new bath with a heated floor, or an ADU often triggers a panel upgrade. We’ll flag it in the written scope instead of surprising you mid-project.

FAQs About General Contractor in South Gate
An ADU or garage conversion in South Gate requires building permits, and depending on the scope, electrical, plumbing, and mechanical permits as well. If your conversion was done years ago without permits, the city may require a retroactive permit process before any new work is approved. We handle the permit package, the inspections, and the sign-offs as part of the written scope. Call (803) 680-2547 for an exact read on your property.
A full kitchen remodel in South Gate usually runs 8 to 14 weeks, depending on whether we’re moving walls, upgrading electrical, or repairing subfloor. Permitted work adds inspection wait times, and homes built between the 1920s and 1950s often have structural surprises that add a week or two. We build the calendar into your written scope so you know the schedule before we start. Call (803) 680-2547 for a timeline on your specific kitchen.
A South Gate home addition often ties into the existing foundation and roofline, which means structural engineering, shear-wall upgrades, and matching new framing to old. A detached ADU is simpler structurally because it stands alone. On a 40- to 50-foot-wide lot, the addition also eats into side-yard setbacks that an ADU at the rear doesn’t. We’ll scope both options before you choose between them. Call (803) 680-2547 to talk through your lot.
A draw schedule means you pay in stages tied to completed milestones, not a lump sum upfront and not a blank check. Each draw is tied to a specific deliverable: demo complete, rough-in complete, drywall up, final inspection passed. The schedule is written into your contract before work begins, so there’s no ambiguity about what triggers a payment. Call (803) 680-2547 and we’ll walk you through a sample schedule for your project type.
Before any South Gate remodel begins, you should have a written scope of work, a line-item price, an allowances list for finishes, a permit plan, a draw schedule, and a written guarantee with stated terms. At Mason Remodeling, all of that is standard on every job, and the 365-Day Done Right Promise means if the work isn’t right within a year of completion, we make it right at no cost to you. Call (803) 680-2547 for a free estimate and a written price on your project.
