Fast, Reliable General Contractor Across Lexington Hills
If you’re planning a remodel, addition, or ADU in Lexington Hills, you already know the first question isn’t “what color cabinets” but rather “what’s behind these walls, and will the county sign off?” That’s exactly where we come in. San Mateo Construction is a licensed general contractor serving Lexington Hills with full exterior-to-interior scope under one contract, from re-roofing and window replacement to kitchen remodels and prefab ADUs. Noel Carrington leads our team, and we’ve worked on enough Lexington Hills properties to know that access, fire-safety review, and unpermitted past work shape every project before a single board is cut. Call us at (855) 901-7266 for a free estimate, and we’ll walk you through what your specific home actually needs.
Why San Mateo Construction Is Lexington Hills’s Preferred General Contractor Company
Lexington Hills homeowners keep calling us because we don’t flinch when a wall comes down and the real house shows up. This is an unincorporated Santa Cruz Mountains community, and most of the housing stock is mid-century mountain cabins, owner-built redwood homes, and scattered custom builds, many on pier-and-beam foundations. Additions and decks were often built without permits decades ago. That means when we open up a Lexington Hills home, we frequently find undersized framing, outdated wiring, and deck guards that wouldn’t pass today’s code. We plan for that from day one, which keeps your project moving and your budget predictable.
Our customers in Lexington Hills value brand-name materials and honest guidance over the lowest possible bid. You’ll choose from curated options like Cambria or Caesarstone countertops, GAF or Owens Corning roofing, and Therma-Tru doors, rather than whatever a supplier happens to have in stock. One contractor manages scheduling, subcontractors, material procurement, and quality control across every trade. No patchwork of separate vendors. No finger pointing between trades when something needs fixing.
Styles & brands we work with







General Contractor Services in Lexington Hills
General Contractor Services in Lexington Hills start with a clear-eyed assessment of what the county will require before you can pull a permit. Because Lexington Hills sits in a high-fire-severity zone, Santa Clara County plan review will stall any addition or remodel unless the site plan shows both the 100-foot defensible-space zone and the septic system’s approved expansion area. That one step gets missed on a surprising number of projects and delays permits by weeks, so we build it into your initial site plan before anything goes to the county.
Whole-Home Remodels with Code Compliance Built In
A whole-home remodel in Lexington Hills typically runs $45,000 to $130,000 depending on scope, and that range reflects the reality of bringing an older mountain house up to current code. We write allowances for electrical upgrades, framing repairs, and waterproofing into the initial contract, so you’re not hit with a tense change-order negotiation once walls are open.

Kitchen and Bathroom Remodels
Kitchen remodels in Lexington Hills run $14,000 to $45,000. Bathroom remodels run $9,000 to $28,000. Both ranges include the kind of surprises we already expect here: outdated wiring behind plaster, failed waterproofing under old tile, and joists that need attention before new cabinets or a walk-in shower can go in.

Construction Company in Lexington Hills
Construction Company work in Lexington Hills means managing the site conditions as much as the build itself. Steep, wooded lots, narrow private roads like those off Old Santa Cruz Highway, and strict county fire-safe and septic rules shape everything from where materials get staged to how concrete arrives. We coordinate that so you don’t have to.
Home Additions and ADUs
Home additions in Lexington Hills run $45,000 to $130,000, and ADU construction runs $90,000 to $220,000. We also build prefab ADUs through vetted manufacturers like Abodu, Dvele, and Plant Prefab, which can compress timelines on lots where traditional stick-built work gets complicated by access and terrain.
Exterior Systems and Structural Repairs
From James Hardie siding to GAF or CertainTeed roofing, we handle the systems that protect a Lexington Hills home from hot, dry summers and winter storms that bring down trees and saturate slopes. Erosion control, drainage, and retaining walls are part of the conversation here, not afterthoughts.
Trusted Brands We Service in Lexington Hills
We carry working relationships with 50+ industry-recognized brands across cabinetry, countertops, plumbing, roofing, windows, siding, hardscaping, fencing, and ADU manufacturing. In Lexington Hills, that means you’re choosing from KraftMaid or Wellborn cabinetry, Kohler or Grohe fixtures, and PGT or Therma-Tru windows, with honest guidance on which tier fits your budget. Need a value-tier option that still performs? We’ll show you Delta or American Standard alongside the premium lines. We’re familiar with the specs and lead times for ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux, so Lexington Hills customers get accurate timelines, not vague promises. No upselling. Just curated choices and a straight answer about what each brand actually delivers.

AfterCommon General Contractor Problems We See in Lexington Hills Homes
- Unpermitted additions and decks. Many Lexington Hills homes have decks and additions built decades ago without permits. When we open up a wall or tie into a deck, we often have to bring framing, electrical, and guard rails up to current code before the new work can proceed. We plan for this in the contract so it doesn’t derail your draw schedule.
- Knob-and-tube wiring and undersized framing. On a pier-and-beam cabin off Old Santa Cruz Highway, our crew opened a wall for a kitchen remodel and found knob-and-tube wiring and undersized floor joists, both common in owner-built mountain homes. We stopped work, wrote a change order with an electrical rough-in allowance and new load-bearing framing, and got the homeowner’s sign-off before proceeding.
- Defensible-space and septic details missing from site plans. Santa Clara County will not approve an addition or remodel in Lexington Hills unless the site plan shows the 100-foot defensible-space zone and the septic system’s approved expansion area. We include both before the first submittal, so your permit review doesn’t stall.
- Concrete truck access on narrow private roads. Roads off Old Santa Cruz Highway can block a standard concrete truck, which means pump-truck or smaller-mix deliveries. We coordinate this before the pour so your foundation or driveway work doesn’t stall mid-project.

FAQs About General Contractor in Lexington Hills
A kitchen remodel in Lexington Hills runs $14,000 to $45,000, and we recommend writing a contingency allowance of 15 – 20% into your contract specifically for electrical, framing, and waterproofing upgrades that older homes commonly need. You’ll see and approve every change in writing before we touch it. Call (855) 901-7266 for a line-item bid specific to your kitchen.
Because Lexington Hills sits in a high-fire-severity zone, Santa Clara County plan review requires the site plan to show the 100-foot defensible-space zone and the septic system’s approved expansion area before an addition or remodel can proceed. Missing either item stalls permit approval by weeks, which is why we include both on the first submittal. We pull permits for every project that requires them.
We assess access during the estimate and coordinate with the concrete supplier before the pour. On roads too narrow for a standard truck, we schedule a pump truck or smaller-mix deliveries so the work isn’t delayed. This is a known Lexington Hills variable, so it’s in our planning, not a surprise on pour day.
We stop work on the affected area, document what we found, and write a change order with a specific scope and price before anything gets altered. We found exactly this on a pier-and-beam cabin off Old Santa Cruz Highway, knob-and-tube wiring and undersized joists, and the homeowner signed off before we proceeded. You’ll never get a surprise invoice for work you didn’t approve in writing.
Yes, we handle design, permitting, and construction for home additions from start to finish. That includes the site plan with defensible-space and septic details, structural drawings, material selection from our brand portfolio, and all inspections. One contractor, one contract, one point of accountability. Call (855) 901-7266 to start with a free estimate.
