Fast, Reliable General Contractor Across South San Francisco
Hiring a general contractor in South San Francisco means finding someone who understands what the city’s older homes hide behind drywall. We’re Ashford Contractors, led by Glen Mossier, and we handle full-scope remodels, additions, ADUs, roofing, windows, hardscape, and everything in between. One contract. One project manager. No runaround when a kitchen wall reveals knob-and-tube wiring or an undersized header. Call us at (877) 752-3868 and we’ll walk your South San Francisco property with you, identify what’s actually there, and put real numbers on paper before you commit to anything.

Why Ashford Contractors Is South San Francisco’s Preferred General Contractor Company
South San Francisco homeowners call us because we’re set up for the city’s specific conditions, not generic Bay Area remodel work. The flatlands near the old industrial corridor sit on undocumented fill and buried foundations from the cement and steel era. We know that going in. That means we run utility locating and soils screening before we open a wall or cut into a slab, which saves you from surprise change orders mid-demo. Homeowners in Sunshine Gardens, Old Town, and the Avalon area have come to expect that from us.
Our reviews from South San Francisco customers consistently mention the same thing: we write everything down. When we find a condition that changes scope, it goes into a written change order with a price, and you approve it before we proceed. No vague verbal agreements. No “we’ll figure it out later.” That discipline matters when you’re spending $16,000 on a kitchen or $106,000 on an ADU.
Response time to South San Francisco is quick. We’re based nearby in Foster City, and our project managers are in South City multiple days a week. Estimates are free, and we schedule them fast.
Styles & brands we work with







Construction Company in South San Francisco
As a Construction Company in South San Francisco, we handle ground-up additions, garage conversions, ADU builds, and structural work on the city’s older housing stock. South San Francisco’s mix of early-1900s worker cottages and mid-century tract homes means almost every project touches framing, foundation, or electrical that hasn’t been updated in 40 to 100 years. A home addition in South San Francisco typically runs $53,100 to $153,400 depending on square footage, site access, and what the soils screening turns up on your lot.
Structural Corrections and Code Upgrades
Older South City homes routinely have load-bearing headers under-sized for their spans, single-layer subfloors that flex under tile, and electrical panels still running 60-amp service. Any remodel that triggers a permit will require bringing those items up to current code. We price those corrections during inspection, not after the walls are open.
Permit Sequencing and Inspection Sign-Offs
South San Francisco’s building department expects scheduled inspections before walls close. We order the rough-in inspection while things are still visible, which prevents destructive rework later. That sequencing is part of our standard process, not an add-on service.
Remodeling Contractor in South San Francisco
As a Remodeling Contractor in South San Francisco, we handle kitchens, bathrooms, whole-home remodels, and everything between. The older a South City home is, the more likely a remodel quote moves once we open things up. That’s not a gotcha; it’s just what’s inside these walls. What matters is how your contractor handles it. We inspect first, build written allowances into the contract, and price every surprise before we touch it. A kitchen remodel in South San Francisco runs $16,520 to $53,100. A bathroom remodel runs $10,620 to $33,040.
Hidden Conditions and Written Allowances
On a 1920s worker cottage in Old Town, our crew opened a kitchen wall to find knob-and-tube wiring spliced into 1960s Romex and a load-bearing header undersized for the span. We stopped, wrote a change order with the structural repair and a rough-in allowance for new circuits, and got sign-off before proceeding. The client later said that written step saved the project from becoming a dispute. That’s how we run every South San Francisco remodel.
Material Selection Without the Upsell
We work with KraftMaid and Wellborn for cabinetry, Cambria and Silestone for countertops, and Kohler, Grohe, and Toto for fixtures. You choose the material tier that fits your budget. We write allowances that reflect real market pricing in South San Francisco, so a KraftMaid selection doesn’t become a surprise change order.

Trusted Brands We Service in South San Francisco
We source from a curated roster of more than 50 name-brand manufacturers across every major home system. That includes cabinet lines like KraftMaid and Wellborn, countertops from Cambria and Silestone, plumbing fixtures from Kohler, Grohe, and Toto, roofing from GAF, CertainTeed, and Owens Corning, and siding from James Hardie. For South San Francisco customers, that roster means you aren’t locked into one supply house’s inventory. We also work with fencing brands like General Contractor Ameristar, Jerith, Bufftech, and ActiveYards when a remodel includes exterior scope. Parts and materials are ordered to South City job sites with realistic lead times, and we stage deliveries around your project’s sequence, not the supplier’s convenience.

AfterCommon General Contractor Problems We See in South San Francisco Homes
- Undocumented fill and buried foundations. The flatlands near the old cement and steel corridor hide industrial debris, abandoned utility lines, and old foundations. Skipping utility locating before excavation leads to surprise change orders mid-demo.
- Knob-and-tube wiring still active in walls. Early-1900s cottages in Old Town and the older flat blocks west of 101 often have original wiring still live behind newer drywall. A permit inspection will flag it, and the fix is new circuits, not a patch job.
- Undersized framing from original construction. Mid-century tract homes in Sunshine Gardens and Avalon were built to lighter standards than today’s code. Load-bearing walls opened for a remodel often need header replacement and engineered lumber.
- Water intrusion at the building envelope. Fog off the San Bruno Gap and wind-driven rain push moisture into older window flashing and siding details. A remodel that opens an exterior wall frequently reveals failed waterproofing that must be corrected before finishes go up.
Pricing for General Contractor in South San Francisco, CA
General contracting prices in South San Francisco reflect the city’s older housing stock and industrial land history. We write fixed-price contracts with line-item allowances for anything that can’t be fully known until walls are open. Below are the ranges we’ve seen across South City jobs over the past several years.
| Project | Typical South San Francisco Range |
|---|---|
| Kitchen Remodel | $16,520 to $53,100 |
| Bathroom Remodel | $10,620 to $33,040 |
| Home Addition | $53,100 to $153,400 |
| ADU Construction | $106,200 to $259,600 |
| Cabinet Installation | $4,720 to $15,340 |
What moves these numbers most is what the walls hide. Older Olmos and Tanforan-area homes with original framing and wiring will land higher than a newer eastside build with clean utilities. We inspect before we quote, and we put any unknown in writing as an allowance with a cap. Estimates are free. Call (877) 752-3868 to set one up.

FAQs About General Contractor in South San Francisco
Knob-and-tube wiring spliced into newer Romex, undersized headers, failed waterproofing, and structural framing that doesn’t meet current code. That’s what we find in South San Francisco’s early-1900s cottages and mid-century tract homes. We handle it with an inspection-first scope and written allowances, so nothing gets priced after the fact without your sign-off. For an exact read on your home, call (877) 752-3868 for a free estimate.
We pull the permits, schedule the inspections, and make sure the inspector sees the work before walls close. South San Francisco’s building department requires rough-in sign-offs before insulation and drywall go up, and we sequence our work around those dates. Rework from a missed inspection window is a cost you should never carry. That’s on us, not you.
Undocumented fill, buried foundations, abandoned utility lines, and soils that sometimes contain industrial slag or debris from the city’s cement and steel era. Any remodel that digs or opens a wall near that corridor needs utility locating and soils screening first. We run that before demo starts on every South City job, which keeps surprises out of the change-order line item.
We write a cabinet installation allowance of $4,720 to $15,340 into the contract, and your KraftMaid or Wellborn selections come out of that allowance. Countertops from Cambria or Silestone are priced the same way. If your selection exceeds the allowance, we tell you in writing before ordering, and you approve the difference. No vague language and no surprise line items at the end. Call (877) 752-3868 and we’ll walk you through the allowance structure before you sign anything.
Yes. That’s the whole point. One contract, one project manager, one point of contact for everything from the roofline to the foundation. Interior remodel, exterior envelope, hardscape, ADU. We handle it in-house with our crews and our material relationships, not a rotating cast of subs you have to chase down.
