AfterConstruction in Los Altos Hills, CA
Roofing, windows, fences, and hardscaping in Los Altos Hills run into conditions you won’t find in neighboring cities: mandatory 1-acre lots, hillside grading ordinances, and Very High Fire Hazard Severity Zone requirements that shape every material choice and permit timeline. Most homes here were built between the 1960s and 1990s, and their original roofing, single-pane windows, and unsealed driveways are now hitting end-of-life simultaneously as owners modernize. Call (669) 271-8644 for a written estimate before any work starts.
This page covers the four trades we deliver most often in Los Altos Hills. If you’re looking for kitchen remodeling, bathroom remodeling, or home additions and ADU construction, we have dedicated pages for those projects with Los Altos Hills-specific pricing and code notes.
Why Los Altos Hills Homes Are Different
Los Altos Hills is California’s only incorporated city that is 100% single-family residential with a mandatory 1-acre minimum lot size and its own strict grading ordinance. Every construction project here is a large-lot custom estate job subject to hillside development review, slope analysis, and impervious-surface limits that do not exist in neighboring Los Altos, Palo Alto, or Cupertino. Contractors who don’t know the city’s specific design-review and grading permit process will face costly delays that neighboring-city experience simply won’t prepare them for.
The housing stock is predominantly large custom homes built between the 1960s and 1990s - many original ranch-style footprints that wealthy tech-industry owners are now tearing down or substantially remodeling into modern estates. A growing wave of ground-up custom builds on lots that frequently involve significant grade changes requires engineered retaining walls, drainage systems, and soils reports as baseline scope items.
Much of the city sits in a Very High Fire Hazard Severity Zone (VHFHZ) designated by CAL FIRE, making fire-resistant construction assemblies - Class A roofing, ember-resistant vents, and ignition-resistant exterior cladding - code-required elements that add both material cost and product-lead-time planning to nearly every exterior project. A large share of parcels rely on private septic rather than municipal sewer, so any addition that increases bedroom count or square footage triggers a Santa Clara County Environmental Health septic-capacity review and often a full leach-field upgrade before the city building department will issue a final permit.
Our Main Los Altos Hills Services
These are the three trades Los Altos Hills homeowners call about most often, each with its own dedicated page for detailed pricing and local code guidance.
Kitchen Remodeling in Los Altos Hills
Kitchen remodels in Los Altos Hills typically involve opening up 1960s-1980s ranch footprints into modern great-room layouts, which means structural beam calculations and often hillside-grading coordination if the expansion pushes toward a slope. We quote every kitchen with a flat written price before work starts, including allowance line items for cabinetry, countertops, and appliances sourced from our vetted brand list. Kitchen Remodeling in Los Altos Hills.
Bathroom Remodeling in Los Altos Hills
Bathroom projects here range from guest-bath updates in original 1970s builds to spa-style primary suites with curbless showers and heated floors. Because many homes rely on private septic, any bathroom addition requires Santa Clara County Environmental Health approval before the city will issue permits - a timeline factor we build into every written quote. Bathroom Remodeling in Los Altos Hills.
Home Additions & ADU in Los Altos Hills
Additions and ADUs in Los Altos Hills face the city’s strict grading ordinance and impervious-surface limits, plus septic-capacity reviews for any bedroom or square-footage increase. We engineer for slope stability, drainage, and fire-resistant assembly requirements from the first site visit, with every cost line-itemed in writing before permits are pulled.

Before
AfterRoofing in Los Altos Hills
Most Los Altos Hills homes were built with cedar shake or early asphalt shingle roofs that are now 30-50 years old, and the city’s VHFHZ designation means replacements must meet Class A fire-resistance standards with ember-resistant venting. We inspect underlayment condition, sheathing integrity, and attic ventilation as standard practice on every Roofing project here, because hillside wind exposure and seasonal temperature swings degrade materials faster than in flatter Santa Clara Valley neighborhoods.
Roof Repair
Signs you need it
Water stains on ceiling drywall, granules collecting in gutters, or lifted shingles along the ridgeline after winter wind events.
What it costs in Los Altos Hills
Roof repair in Los Altos Hills typically runs $400-$1,800 depending on whether we’re replacing a few damaged shingles, resealing vent penetrations, or patching underlayment where hillside wind has driven water past the primary barrier.
How we do it
We photograph the full roof surface from a ladder or drone, mark each defect on a diagram, replace damaged materials with fire-rated equivalents, and deliver a photo record of the completed repair with a written warranty.
Roof Replacement & Installation
Signs you need it
Multiple leak points, visible sagging in the roof plane, or shingles that have exceeded their rated lifespan and are no longer eligible for manufacturer warranty coverage.
What it costs in Los Altos Hills
Roof replacement in Los Altos Hills typically costs $8,000-$20,000 for asphalt shingle systems, with Class A fire-rated materials and ember-resistant vent upgrades included in the written scope.
How we do it
We strip to sheathing, replace deteriorated decking, install fire-resistant underlayment and Class A shingles or tiles, upgrade all vents to ember-resistant models, and schedule city and fire-department inspections before final payment.
What Roofing Costs in Los Altos Hills
| Item | Typical range in Los Altos Hills |
|---|---|
| Roof Repair | $400 - $1,800 |
| Roof Replacement | $8,000 - $20,000 |
| Metal Roof Installation | $15,000 - $40,000 |
How long does a roof replacement take in Los Altos Hills?
Most asphalt shingle replacements take 3-5 working days, but hillside lots with limited access or crane requirements can extend to 7-10 days. We include the realistic timeline in the written quote, not an optimistic one. Call (669) 271-8644 for a site-specific estimate.
Do I need a fire department inspection for roofing in Los Altos Hills?
Yes, the VHFHZ designation requires fire-resistant assembly verification; we pull the permit, schedule the inspection, and pass it before final invoice. The permit cost is line-itemed in your written quote. Call (669) 271-8644 to schedule your free estimate.
Windows & Doors in Los Altos Hills
The original single-pane aluminum windows in most Los Altos Hills homes conduct heat and cold at rates that modern energy codes would reject, and their frames often show corrosion from hillside moisture exposure. We specify replacement windows and doors that meet or exceed California Title 24 requirements while standing up to the temperature swings and fire-zone venting rules that Windows & Doors projects face here.
Window Replacement
Signs you need it
Condensation between panes, difficulty opening or closing sashes, or visible frame rot or aluminum oxidation that compromises the weather seal.
What it costs in Los Altos Hills
Window replacement in Los Altos Hills typically runs $4,500-$15,000 for a whole-house project, depending on unit count, egress requirements, and whether we’re upgrading to tempered or laminated glass for fire-zone compliance.
How we do it
We measure each opening to 1/8-inch tolerance, order from ECO Window Systems or CWS with confirmed lead times, install with proper flashing and sealant, and photograph every unit before and after to document the weather seal.
Impact Windows & Doors
Signs you need it
Large expanses of glass facing prevailing winds, or a preference for single-layer protection that eliminates the need for separate storm shutters in severe weather events.
What it costs in Los Altos Hills
Impact window and door installation in Los Altos Hills typically costs $8,000-$25,000, with laminated glass and reinforced frames rated for both debris impact and forced-entry resistance.
How we do it
We engineer for structural load transfer at each rough opening, install impact-rated frames with structural silicone glazing, and provide documentation for insurance discounts and resale disclosure.
What Windows & Doors Costs in Los Altos Hills
| Item | Typical range in Los Altos Hills |
|---|---|
| Window Replacement | $4,500 - $15,000 |
| Impact Window Installation | $8,000 - $25,000 |
Can I replace windows without replacing the frames in Los Altos Hills?
Insert replacement is possible if the existing frames are square and structurally sound, but most 1960s-1980s aluminum frames in Los Altos Hills are too corroded for reliable sealing; we assess and document this during the free estimate. Call (669) 271-8644 to schedule.
Do new windows require fire-zone certification in Los Altos Hills?
Exterior windows in the VHFHZ must meet ignition-resistant standards for the frame and surrounding wall assembly; we specify compliant products and include the certification documentation in the project file. Call (669) 271-8644 for a written quote with line-itemed materials.
Fence Installation in Los Altos Hills
With 1-acre minimum lots and frequent slope changes, Los Altos Hills fence projects are rarely straightforward perimeter jobs; they require stepped or racked installations, retaining-wall integration, and often design-review approval for height or materials. We survey the grade, check property lines against recorded maps, and confirm HOA or city design guidelines before quoting any Fence Installation project here.
Vinyl Fence
Signs you need it
A perimeter that needs low maintenance and clean sight lines, or replacement of a wood fence that has rotted at the post base due to hillside drainage patterns.
What it costs in Los Altos Hills
Vinyl fence installation in Los Altos Hills typically runs $3,500-$9,000, with routed posts and rails that handle thermal expansion better than bracketed systems in our temperature-swing climate.
How we do it
We set posts in concrete below the frost line with gravel drainage, rack or step panels to follow grade within manufacturer tolerance, and cap posts to prevent water intrusion that degrades the hollow vinyl over time.
Aluminum Fence
Signs you need it
Pool enclosures, estate entry gates, or perimeter security where wrought-iron aesthetics are desired without the maintenance burden of welded steel.
What it costs in Los Altos Hills
Aluminum fence installation in Los Altos Hills typically costs $4,000-$10,000, with powder-coated tubular rail systems that resist corrosion without requiring the periodic repainting that steel demands.
How we do it
We core-drill into concrete or set posts in excavated footings with rebar reinforcement, level and plumb each section across sloped terrain, and provide a touch-up kit for any field scratches to the powder coat.
What Fence Installation Costs in Los Altos Hills
| Item | Typical range in Los Altos Hills |
|---|---|
| Vinyl Fence Installation | $3,500 - $9,000 |
| Aluminum Fence Installation | $4,000 - $10,000 |
Does Los Altos Hills require a permit for fence installation?
Fences over 6 feet or on slopes with significant grade change typically require a grading or building permit; we verify requirements with the city and include permit costs in the written quote. Call (669) 271-8644 for a free site assessment.
How do you handle fence installation on sloped lots?
We use stepped installations for moderate grades and custom-racked panels for continuous slopes, always with concrete footings that account for lateral soil pressure on hillside terrain. Call (669) 271-8644 to schedule your estimate with a written grade plan.
Driveway & Pavers in Los Altos Hills
Original driveways in Los Altos Hills are often cracked asphalt or unreinforced concrete from the 1970s, now failing under the weight of modern vehicles and compromised by oak root intrusion and seasonal groundwater movement on hillside lots. The city’s impervious-surface limits also mean replacement projects must account for drainage and permeability requirements that Driveway & Pavers contractors from flatter cities may not anticipate.
Paver Driveways
Signs you need it
Spiderweb cracking in concrete that has exceeded repair, poor drainage pooling at the garage threshold, or a desire for permeable surfacing that counts favorably against impervious-surface limits.
What it costs in Los Altos Hills
Paver driveway installation in Los Altos Hills typically runs $7,000-$18,000, with Belgard or Techo-Bloc permeable pavers, open-graded base, and edge restraint engineered for vehicle loads on sloped approaches.
How we do it
We excavate to engineered depth, install geotextile and compacted aggregate base in lifts, set pavers with consistent joint spacing, sweep in polymeric sand, and compact with a plate vibrator before sealing.
Concrete Driveways & Concrete Work
Signs you need it
Alligator cracking, settlement at the apron, or spalling from freeze-thaw cycles and de-icing salt exposure on north-facing slopes that stay shaded through winter mornings.
What it costs in Los Altos Hills
Concrete driveway installation in Los Altos Hills typically costs $4,500-$12,000, with steel reinforcement, control joints at calculated intervals, and a broom or exposed-aggregate finish specified in the written scope.
How we do it
We form to grade with proper slope for drainage, place rebar or wire mesh on chairs, pour with 4,000 PSI minimum concrete, screed and float to finish, and saw-cut control joints within 24 hours to prevent random cracking.
What Driveway & Pavers Costs in Los Altos Hills
| Item | Typical range in Los Altos Hills |
|---|---|
| Paver Driveway Installation | $7,000 - $18,000 |
| Concrete Driveway Installation | $4,500 - $12,000 |
| Asphalt Driveway Paving | $3,500 - $9,000 |
Do paver driveways count against impervious-surface limits in Los Altos Hills?
Permeable paver systems with open-graded base often qualify as partially pervious in the city’s calculation, but the specific percentage depends on joint width and base depth; we confirm the math with the planning department before quoting. Call (669) 271-8644 for a written estimate with the pervious-calculation included.
How long does a paver driveway last compared to concrete?
Properly installed pavers on a compacted aggregate base typically last 30-50 years with periodic joint sand refresh, while concrete in our climate shows significant cracking within 15-25 years without major intervention. Call (669) 271-8644 for a lifecycle-cost comparison in your written quote.
