Fast, Reliable Home Remodeling Across Colma
Home remodeling in Colma, CA typically runs $9,000 – $45,000 for kitchens and baths, $45,000 – $130,000 for additions, and requires a contractor who understands what hides inside the town’s post-1950s stucco homes. We’re Millwright Builders, led by Noel Castañeda, and we’ve worked on enough Colma ranchers to know that opening a wall here rarely reveals what the original floor plan suggested. The fog off the cemetery belt keeps exterior assemblies damp, wiring is often original, and the permit review process is tighter than most towns. Call (866) 925-0334 to schedule a free estimate before you commit to a scope of work.
We serve the 94015 ZIP and the neighborhoods around Hillside Boulevard, F Street, and Serramonte, so we’re never far from a Colma job site. When you call, we schedule a walkthrough, test wall cavities for moisture, and write a quote that accounts for what we can verify, not just what we can see.
Why Millwright Builders Is Colma’s Preferred Home Remodeling Company
Colma’s housing stock is small and specific. Most homes are single-story stucco on compact lots, built between the 1950s and 1970s, and many have never been opened up for a full renovation. That means the contractor you choose is making decisions about framing, wiring, and waterproofing that were last inspected when the house was built. We know those assemblies because we’ve worked inside them on Hillside Boulevard, along F Street, and in the 94015 neighborhoods near the BART corridor.
Noel Castañeda runs every Colma project as a true general contractor, meaning one contract covers structural work, finish carpentry, window and door replacement, and hardscape if the job extends outdoors. Most remodelers stop at drywall and paint. We don’t. From the roofline to the back patio, one contractor, one conversation.
Colma homeowners also get something most contractors can’t offer: a builder who specifies the brand, explains the trade-off, and stands behind the install. Your renovation shouldn’t require you to become a project manager.
Styles & brands we work with







Home Remodeling Companies in Colma
Home Remodeling Companies in Colma fall into two loose groups: trade-specific specialists who handle one scope, and licensed general contractors who run the full job. We’re the second type. A Colma remodel often starts as a kitchen or bath but turns into structural repair, window replacement, or an electrical upgrade once permits trigger code requirements. That’s where a specialist exits and a general contractor stays.
On a typical Colma project, we pull permits, open walls, document what we find, and issue written change orders before work proceeds beyond the agreed scope. The town reviews remodel files against a small, well-known set of older plans, so our paperwork has to be precise. We treat that as a feature, not a hurdle. Inspection sign-off happens before drywall closes, not after.
Kitchen and Bath Scope
A Colma kitchen remodel runs $14,000 – $45,000 depending on cabinet line, countertop material, and what the walls reveal. Bath remodels run $9,000 – $28,000. We write allowances for rough-in work into every contract so the quote reflects reality, not optimism.
Whole-Structure Coordination
When a remodel triggers a window or roof repair, one contract covers it. We install windows from PGT and Therma-Tru, roofing from GAF or Owens Corning, and siding from James Hardie without handing you a phone to coordinate subs.
Whole House Remodel in Colma
A Whole House Remodel in Colma means opening more than one room and usually repositioning mechanical, plumbing, or structural systems along the way. These projects run $45,000 – $130,000 for most ranchers in the 94015 ZIP, with additions or ADUs pushing higher. The value isn’t just in new finishes. It’s in replacing the parts of the house that have been quietly failing behind stucco for decades.
In Colma, the damp fog off the cemetery belt keeps exterior sheathing wet for long stretches every year. When we open a wall, we routinely find rusted strapping, soft sheathing, and undersized framing long before anything cosmetic shows up. That’s not a reason to avoid remodels. It’s a reason the quote needs to anticipate it.
Inspection and Allowance Structure
We scope a whole-house remodel in stages: first the walkthrough and moisture testing, then a written scope with allowances for framing, rough-in, and sheathing repair, then the permit application. Every surprise gets priced and approved in writing before we touch it. No work proceeds on a verbal nod.
Sequencing the Job
A full Colma remodel moves in a deliberate order: demo, structural repair, rough-in, inspection, then finishes. Cabinets from KraftMaid or Wellborn and quartz from Cambria or Caesarstone go in after the building is dry and signed off. That sequencing is why our jobs stay on schedule when other crews stall out on unknowns.
Trusted Brands We Service in Colma
We specify brands with manufacturer warranties and installation requirements we’re already trained on. That includes Cambria and Caesarstone quartz, GAF and Owens Corning roofing, PGT and Therma-Tru windows and doors, James Hardie siding, and Kohler, Grohe, Toto, and Blanco fixtures. We also source hardscape materials from Quikrete and Sakrete for Colma driveways and patios. For ADU work, we’re set up to install Abodu units alongside conventional site-built additions. Every product we install, we’ve vetted, not just stocked.

AfterCommon Home Remodeling Problems We See in Colma Homes
- Fog-damp wall cavities. Colma’s persistent summer fog keeps exterior stucco assemblies wet for months, and we’ve opened walls on Hillside Boulevard with sheathing that had been swelling for years. Moisture testing before quoting is standard on our Colma jobs.
- Original 1950s wiring. Many ranchers in the 94015 ZIP still run the original cloth-sheathed conductors. A remodel that opens a wall triggers electrical upgrades, so we write that into the allowance instead of surprising you after demo.
- Undersized framing at openings. The original window and door headers in post-1950s Colma homes often fall short of current code once a permit is pulled. We inspect and replace them as part of the structural scope, with sign-off at inspection.
- Cemetery-adjacent excavation limits. For homes near the memorial parks, any trenching or foundation work has to be coordinated with cemetery operators and done with dust control and noise restrictions in mind. We hand-dig where the maps, and the cemetery crews, tell us to.

FAQs About Home Remodeling in Colma
Because most Colma homes were built in the 1950s and 1960s with original wiring, questionable waterproofing, and framing that often fails current code once a permit is pulled. Any honest contractor writes allowances for those unknowns into the contract. If a quote doesn’t include a rough-in allowance, the change order after demo will be the real price. Call (866) 925-0334 and we’ll walk you through how our allowance line items work before you sign.
Yes. Colma reviews remodel permits against a small, well-known set of older plans, and any structural, electrical, or plumbing change requires inspection sign-off before walls close. We pull permits on every Colma project and sequence the work so inspection happens before drywall, not after. Skipping that step leaves the closed walls unverified and the punch list unresolved.
Mostly the original 1950s cloth-sheathed copper, sometimes with added circuits from later remodels of varying quality. When a remodel opens a wall, the electrical has to be brought up to current code, and we show you exactly what that costs in writing before we proceed. You’ll see it as a line item or allowance, not a surprise at final billing.
We test wall cavities for moisture before quoting, then replace damaged sheathing, add proper WRB (weather-resistant barrier), and detail flashings so the new assembly dries to the outside. Colma’s damp fog off the cemetery belt is relentless, and closing wet framing behind new drywall is how mold and rot become a warranty problem. We don’t do that.
Often yes, and on Colma’s small-lot ranchers it’s usually the smart move. Keeping walls where they are means less framing, fewer permit triggers, and lower mechanical rework. What you won’t save on is what’s already failing behind the stucco. The wiring, sheathing, and undersized headers still have to be fixed once the inspector sees them. Call (866) 925-0334 and we’ll tell you what’s realistic for your floor plan.
