We’ll walk your property, look at your drainage and slope conditions, and give you a written line-item quote before anything gets opened up.

Why Ashford Contractors Is Highlands-Baywood Park’s Preferred General Contractor Company
Highlands-Baywood Park homeowners call us because we treat a remodel as what it is: a structural, electrical, waterproofing, and permit-driven project, not a cosmetic one. Glen Mossier leads our team with a simple rule. Open the wall, document what’s there, price the fix, get approval in writing, then move. That approach matters in this area, where mid-century ranch and split-level homes on steeply graded lots hide decades of deferred maintenance behind drywall. We don’t flinch when we find cloth-wrapped wiring or a rotted rim joist. We photograph it, explain it, and attach a number to it.
Our reputation in Highlands-Baywood Park is built on showing up with a plan that already accounts for county inspections, slope-stability questions, drainage corrections, and tree-protection review. Homeowners tell us the difference is immediate: no mid-project calls about “unforeseen conditions” that were actually foreseeable to anyone who’s worked these hills. That’s the local knowledge that keeps projects on schedule and budgets honest.
Styles & brands we work with
Residential General Contractor in Highlands-Baywood Park
A Residential General Contractor in Highlands-Baywood Park is responsible for managing every trade, every permit, and every inspection on a home renovation, from demolition through final county sign-off. Here, that role carries extra weight because unincorporated San Mateo County building standards apply, and sloped lots frequently trigger geotechnical, drainage, and retaining-wall scrutiny that flatter neighboring cities don’t impose the same way. We handle the full package: structural work, electrical and plumbing rough-ins, framing, waterproofing, finishes, and exterior scopes like roofing, siding, decks, and hardscape. A typical kitchen remodel here runs $14,000 – $45,000, while a bathroom remodel lands in the $9,000 – $28,000 range depending on scope and material selection.
Structural and Permit Work
When a Highlands-Baywood Park homeowner opens up a load-bearing wall or adds square footage, the structural changes have to pass county inspection. We pull every permit through San Mateo County, schedule inspections, and coordinate with the geotech engineer when slope stability is in play. That’s not an add-on service here; it’s standard procedure on nearly every hillside lot.
Interior and Exterior Scope Together
Most of our Highlands-Baywood Park projects touch more than one system. A kitchen remodel might lead to a rotted deck threshold, a bathroom remodel might expose a failed waterproofing membrane, and an addition might force drainage corrections on the downhill side. We’re structured to handle it all under one contract, which keeps you from juggling three separate crews and three separate schedules.
Hire a General Contractor in Highlands-Baywood Park
When you Hire a General Contractor in Highlands-Baywood Park, you’re hiring the single point of accountability for the entire project, not a coordinator who shuffles papers while subs make decisions on their own. Glen Mossier and our team carry every scope, interior and exterior, from the roofline to the foundation. We bid full-scope renovations honestly, with allowances written into the contract for the things we know we’ll find in this housing stock: outdated electrical, undersized framing, and water damage from years of fog-driven moisture at deck thresholds and window openings. Home additions in this area range $45,000 – $130,000, and an ADU runs $90,000 – $220,000 depending on site conditions and prefab versus stick-built.
Walls-Open Pricing Protocol
Here’s the rule we work by in Highlands-Baywood Park. We inspect before we bid, we write allowances into the contract for known unknowns, and we never start unapproved work. If we open a wall and find something the original scope didn’t cover, we stop, document it, and price it as a written change order. You approve it, then we build it. That’s how we avoid unsigned change orders and budget drift.
County Permit Management
Every permit here goes through San Mateo County, not a city hall. We file, schedule, and manage inspections, including geotech and drainage review on steep lots. If you’ve got a hillside property with mature oaks or redwoods, we build tree-protection requirements into the plan from day one, not after the inspector flags them.
Trusted Brands We Service in Highlands-Baywood Park
We source materials from a curated roster of more than 50 manufacturers, so Highlands-Baywood Park homeowners get real choice on every product category, not a single upsell option. On fencing and hardscape projects, we work with names like Master Halco, Ameristar, and Jerith for professional-grade materials that hold up to coastal fog and winter rain. On interiors, we install cabinetry from KraftMaid and Wellborn, countertops from Cambria and Silestone, and plumbing fixtures from Kohler, Moen, and Toto. Because we stock and order locally throughout the 94497 area, material lead times stay predictable and our crews aren’t waiting on trucks from out of state.

AfterCommon General Contractor Problems We See in Highlands-Baywood Park Homes
- Outdated wiring behind mid-century drywall. Homes built in the 1950s through 1970s often still have cloth-wrapped or ungrounded circuits. Opening any wall for a remodel usually triggers an electrical upgrade to meet current county code.
- Fog-driven water intrusion at deck thresholds. Years of coastal fog and heavy winter rain soak into door openings and deck connections. We routinely find softened subfloors and rim joists that need repair before finish work starts.
- Undersized framing on original structures. Many original ranch and split-level homes were framed to older standards. Adding a floor or changing load paths exposes beams and headers that don’t meet today’s requirements.
- Slope and drainage failures on hillside lots. Steeply graded lots in Highlands-Baywood Park move water downhill fast during wet winters. Without proper retaining walls, French drains, and surface grading, foundations and lower-level rooms take the hit.

FAQs About General Contractor in Highlands-Baywood Park
We build the drainage scope into the dry-season plan so the structure works when the winter rains hit. On a Highlands-Baywood Park deck project, that means pulling a county permit, checking slope stability and tree-protection rules, installing proper flashing and drainage at the house connection, and ensuring subgrade water has somewhere to go. On a retaining wall, we spec drainage gravel, weep holes, and a foundation that won’t wash out. The goal is a structure that’s ready for wet weather, not one that fails at the first storm. Call (877) 752-3868 to walk your project with us.
Yes, every permit for work in Highlands-Baywood Park goes through San Mateo County’s building department, and we handle that entire process. That includes geotechnical review on sloped lots, drainage and retaining-wall checks, and tree-protection compliance. We schedule the inspections and stand behind the work through final county sign-off.
We document what we find, price it as a written change order, and get your approval before doing the work. On a recent split-level ranch off a wooded hillside lot in the 94497 pocket, our crew opened up a kitchen wall for a load-bearing change and found cloth-wrapped wiring and a subfloor softened by years of fog-driven water intrusion at the deck threshold. We stopped, documented it, and priced the electrical rough-in upgrade and subfloor repair as a written change order before touching anything, then carried the county permit through its inspection sign-off with the geotech and drainage scope already built into the contract. That’s how we work on every project.
It’s not necessarily more expensive, but the scope is often different. Because Highlands-Baywood Park is unincorporated county land, permits, geotech, and tree removal run through San Mateo County, not a neighboring city hall. On steeply graded lots, that means slope-stability and drainage work gets built into the project in ways flatter neighboring cities don’t require. We price those items line by line so you’re not paying hidden fees, just real construction scope. For an exact quote, call (877) 752-3868.
We stand behind our workmanship with a written warranty, and the materials we install carry their manufacturer warranties as well. Because we work with brands like GAF, James Hardie, Kohler, and KraftMaid, your product-level coverage comes directly from the manufacturer. We walk every Highlands-Baywood Park client through exactly what’s covered before the project starts.
