Fast, Reliable General Contractor Across Lexington Hills
Finding a general contractor who understands Lexington Hills means hiring someone who treats your project like a mountain build, not a valley job. Milpitas Construction handles additions, decks, roofing, ADUs, and whole-home remodels on the steep, wooded parcels that define this part of unincorporated Santa Clara County. We know the private lanes, the County permit desk, and the slope and drainage realities that flatlanders never see. Call Ken Stafford’s team at (877) 752-4194 for a free estimate with real line-item numbers.
Why Milpitas Construction Is Lexington Hills’s Preferred General Contractor Company
Lexington Hills homeowners keep calling us back because we bid the job the way mountain work actually goes: access planned, drainage addressed, County sign-offs scheduled. Our customers here above Los Gatos tell us the same thing: other contractors either underbid and came back with change orders, or never pulled the right permits for unincorporated land. We don’t play that game. A written scope, a clear draw schedule, and one accountable point of contact from the first stake-out to the final inspection is how we run every Lexington Hills project.
Response time to Lexington Hills matters because winter rain doesn’t wait for a callback. When a retaining wall starts moving or a hillside deck shows rot, you need someone who can get on the lane, assess it, and price it correctly the first time. We’re already working in 95031 and the surrounding mountain roads regularly, so we’re not guessing at logistics. Our reputation in Lexington Hills is built on showing up when we say we will and putting the real numbers on paper before the first shovel moves.
Ken Stafford leads every project with a simple rule: name the materials, price the access, and write down the permit path. That’s what a full-scope General Contractor should do on a hillside lot, and it’s the standard we hold every trade and vendor to on your property.
Styles & brands we work with







Hire a General Contractor in Lexington Hills
Hire a General Contractor in Lexington Hills means you’re bringing in someone who manages the whole job, not just the pretty finish work. On mountain parcels here, the general contractor is the difference between a project that clears County inspection and one that stalls half-dug with winter rain coming. We handle everything from structural scopes like decks, additions, and retaining walls to full kitchen and bath remodels inside the same house. Home Additions in Lexington Hills typically run $45,000 – $130,000, ADU Construction $90,000 – $220,000, and a Roof Replacement $8,000 – $20,000.
Access and staging planned before the bid
A Lexington Hills quote has to account for whether a concrete truck fits your lane. If it doesn’t, the pump truck and smaller equipment go into the bid upfront, not as a surprise later. We walk every site before pricing so the number you get is the number you build against.
One contract, one accountable team
We don’t hand you three subs and wish you luck. From foundation formwork to the cabinet pulls, one contract covers the scope, one team owns the schedule, and one phone call reaches the person accountable. For a Lexington Hills homeowner, that matters more on a steep lot than anywhere in the valley.
General Contractor Services in Lexington Hills
General Contractor Services in Lexington Hills span the full exterior-to-interior range because mountain homes don’t fail one trade at a time. A wet winter exposes a roof leak, a failing french drain, and a spongy deck rim all in the same season, and you shouldn’t have to coordinate three separate companies on a road that barely fits one truck. We scope the whole house: roofing, windows, siding, decks, fencing, pavers, kitchens, baths, and ADU or prefab builds. A Paver Driveway Installation here runs $7,000 – $18,000, while Concrete Driveway Installation runs $4,500 – $12,000, and a Garage Conversion lands between $30,000 and $80,000.
Exterior-to-interior scope under one roof
We’ve torn off a roof and tiled the kitchen in the same phase. That’s not a sales pitch, it’s what single-contract work looks like. The same crew protecting your home from rain is the team managing lead times on your cabinetry.

Prefab and ADU construction as a current specialty
We work with modern prefab manufacturers including Abodu, Dvele, Mighty Buildings, Boxabl, and Plant Prefab. On a constrained Lexington Hills parcel, prefab often makes more sense than stick-built, and we’re one of the few general contractors in the area who can actually manage the foundation, utility hookups, and County sign-off for these systems.

Trusted Brands We Service in Lexington Hills
Lexington Hills homeowners deserve to know what’s going into their home by name, not by vague “contractor grade” hand-waving. We spec and install from a verified portfolio of 50+ brand-name product lines: Cambria and Caesarstone countertops, KraftMaid and Wellborn cabinetry, Kohler and Grohe fixtures, James Hardie siding, GAF and CertainTeed roofing, and window and door systems from Therma-Tru, PGT, ECO Window Systems, and ES Windows. Because we keep relationships with these manufacturers current, we can source replacement parts and warranty service for Lexington Hills jobs faster than a general contractor who orders from whatever supply house is cheapest that week. You’ll choose from proven, contractor-grade tiers, not big-box off-the-shelf options.
Common General Contractor Problems We See in Lexington Hills Homes
- Underbid access costs. A contractor quotes a valley price, then discovers a concrete truck can’t make the turn off the private lane. The pump truck and smaller equipment suddenly appear as a change order. We price access before you sign anything.
- Skipped County permitting on unincorporated land. Treating a Lexington Hills deck rebuild or addition like a city job means missing fire-hardening and slope/drainage review that Santa Clara County requires but Los Gatos city hall would never ask for. That stalls the permit and can trigger a stop-work order.
- No written scope on grade work. A retaining wall or hillside deck starts as one scope, then “we found bad soil” becomes a $20,000 surprise. Our written scope and allowances lock the numbers before excavation begins.
- Wet-season scheduling failures. Contractors who don’t work in the mountains underestimate how winter rain stops concrete pours and rough-in work. We sequence the job around the wet window, and the schedule reflects it from day one.

AfterPricing for General Contractor in Lexington Hills, CA
Lexington Hills pricing carries a mountain premium because the work does. Access, slope, drainage, and County fire-hardening all go into a bid here that a Campbell or San Jose job never sees. The table below reflects what we’re actually quoting across 95031 right now. These aren’t internet averages, they’re the ranges we write into Lexington Hills contracts.
| Scope | Typical Range in Lexington Hills |
|---|---|
| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |

| Concrete Driveway Installation | $4,500 – $12,000 |
| Paver Driveway Installation | $7,000 – $18,000 |
What moves your number within these ranges? A flat pad with easy truck access lands at the low end. A sloped site requiring pump trucks, extra drainage, or a longer private lane approach lands higher. You’ll see all of that in writing before you commit. Call (877) 752-4194 and we’ll give you the exact line-item estimate for your parcel, free.
Working on a Tight Lexington Hills Lot: Staging, Noise, and Neighbors
Lexington Hills isn’t a subdivision with wide streets and generous setbacks. It’s narrow private lanes, steep driveways, and neighbors who can hear your saw from three lots over because sound travels differently up here. We plan for that reality before we bid. Staging happens on the flattest section of your pad, never on the lane itself unless there’s no alternative, and we schedule deliveries in coordinated drops rather than a constant parade of trucks. Pump trucks, not concrete mixers, handle pours where the lane can’t take the weight. For tight-lot work, we sequence demo and rough-in around County inspection windows so nothing sits open longer than it has to.
Because Lexington Hills is unincorporated Santa Clara County land rather than a city, every scope runs through County permitting, including fire-hardening and slope/drainage review that flat-valley city jobs never trigger. That’s not a hassle we route around, it’s the framework we build the schedule on. If a neighbor needs to know the work plan, we give them the written scope and timing sheet. Clean site, clear communication, and a parking plan that doesn’t block the lane keep the whole street on your side through the project.

FAQs About General Contractor in Lexington Hills
A Lexington Hills bid includes access, slope, drainage, and County fire-hardening costs that a flat-valley city job never triggers. Steep private lanes often can’t take a standard concrete or delivery truck, so pump trucks and smaller equipment go into the price upfront. Every quote we write for Lexington Hills reflects the actual logistics of your specific parcel, not a valley baseline with surprises later. Call (877) 752-4194 for a free estimate that includes these numbers on paper.
You need Santa Clara County permits because Lexington Hills is unincorporated county land, not within Los Gatos city jurisdiction. That means slope/drainage review, fire-hardening requirements, and County inspections all apply. We handle the permit package and the inspection scheduling as part of our general contractor scope. A deck rebuild or addition without the right County sign-off can get cited and red-tagged, so don’t skip it.
We stage on the flattest section of your pad, schedule deliveries in coordinated drops instead of constant truck traffic, and keep the lane clear. Demo debris gets tarped and hauled on the same schedule it’s created, and we share the work plan with adjacent neighbors before loud phases start. A clean, organized site on a tight Lexington Hills lot keeps the whole street cooperative, and that’s protection for your schedule. Call (877) 752-4194 to talk about your site’s specific constraints.
Winter rain in the Santa Cruz Mountains stops concrete pours, slows rough-in, and turns unprotected slopes into erosion problems. A proper Lexington Hills schedule books wet-sensitive phases outside the heaviest rain windows and sequences grading and drainage work before the ground saturates. We’ve built plenty of decks and additions through rainy seasons by protecting the site and working between fronts. Your written schedule will show exactly where the wet-season risk sits in the timeline.
Yes, we handle fire-hardening and roof replacement as part of a larger Lexington Hills remodel, and we typically recommend doing them together because both run through the same County permit and inspection path. We spec Class A assemblies from GAF and CertainTeed, install ember-resistant venting, and integrate siding and deck upgrades from James Hardie and fire-rated brands. Combining these scopes saves you staging and inspection cycles. Call (877) 752-4194 and we’ll fold it all into one written estimate.
