AfterConstruction in Los Altos, CA
Roofing in Los Altos runs $400-$20,000 depending on scope, with most repairs falling under $1,800 and full replacements between $8,000-$20,000. The city’s 1950s-1970s ranch housing stock, combined with winter rains and summer thermal cycling on south-facing slopes, means we see more cracked composition shingles and failed valley flashings here than in newer Bay Area communities. Our crews coordinate dispatch from the San Francisco Bay Area office and carry GAF and Owens Corning systems sized for the low-pitch roofs common on original Los Altos ranches. Call (669) 215-4852 for a written estimate before any work starts.
Why Los Altos Homes Are Different
Los Altos sits on Santa Clara Valley adobe clay soils that swell with winter rains and shrink through the dry months, a cycle that cracks foundations and shifts framing over time. Most homes are post-WWII single-story ranches with original slab-on-grade construction, 100-amp electrical panels, and galvanized or early copper plumbing that was never designed for today’s loads. The city’s extraordinary land values have created an active teardown-and-rebuild market where modest ranches on 8,000-12,000 square foot lots are replaced with 4,000-5,000 square foot custom homes, but the Heritage Tree Ordinance adds complexity: protected valley oaks require arborist oversight, root-zone exclusion zones, and sometimes foundation redesigns before planning will sign off. Contractors who underestimate this constraint on first bids often face weeks of delay and real cost additions.
Our Main Los Altos Services
Los Altos homeowners call us most often for whole-home transformations and expanded living space. These three trades represent the majority of our project volume in the city.
Kitchen Remodeling in Los Altos
Kitchen remodeling in Los Altos typically involves opening up the closed galley layouts common in 1950s-1960s ranches, upgrading undersized electrical service, and specifying finishes that match the expectations of a teardown-and-rebuild market. We quote every project with a flat written price and signed scope before demolition begins. See our dedicated page for Kitchen Remodeling in Los Altos.
Bathroom Remodeling in Los Altos
Bathroom remodeling here often means replacing original cast-iron tubs, relocating plumbing to accommodate larger showers, and ventilating properly in homes where original fans were never installed. The combination of aging galvanized drains and high groundwater in winter makes moisture management a priority on every job. See our dedicated page for Bathroom Remodeling in Los Altos.
Home Additions & ADU in Los Altos
Home additions and ADU construction in Los Altos must navigate the city’s planning department, the Heritage Tree Ordinance, and soils that often require engineered post-tension or deep-pier foundations for any substantial new footprint. We have delivered ADUs and second-story additions on lots where root zones forced complete redesigns. See our dedicated page for Home Additions & ADU in Los Altos.

Before
AfterRoofing in Los Altos
Most Los Altos roofs are low-slope composition shingle systems installed in the 1980s-1990s on ranch homes with minimal attic ventilation, which accelerates thermal degradation on south and west exposures. Winter rains then exploit the brittle tabs, sending water into the original redwood fascia and soffit assemblies that were never designed for repeated wet-dry cycling. Our Roofing crews carry GAF Timberline HDZ and Owens Corning Duration systems with proper ridge venting specified for each roof geometry.
Roof Repair
Signs you need it
Curled or missing composition tabs in the valley areas, water stains on ceiling drywall near chimney penetrations, and granule accumulation in gutters after winter storms are the three indicators we document most often in Los Altos.
What it costs in Los Altos
Roof repair in Los Altos typically runs $400-$1,800 depending on whether the scope is localized shingle replacement, valley flashing rebuild, or structural repair to water-damaged fascia.
How we do it
We photograph the full roof condition from the ridge, remove damaged material to the decking, install matching GAF or Owens Corning shingles with ice-and-water shield at valleys and penetrations, and deliver a documented photo record of the completed repair.
Roof Replacement & Installation
Signs you need it
Multiple leak points, visible daylight through the attic decking, or a shingle layer count exceeding two with the original wood shake still buried beneath are clear indicators that repair economics have failed.
What it costs in Los Altos
Roof replacement in Los Altos ranges from $8,000-$20,000 for composition shingle systems, with final price driven by roof complexity, decking condition, and whether the home requires structural reinforcement for tile or metal upgrades.
How we do it
We strip to bare decking, replace deteriorated sheathing, install synthetic underlayment and proper ridge ventilation, then apply the specified GAF or Owens Corning system with a written 365-Day Done Right Promise backed by The Haven Standard.
What Roofing Costs in Los Altos
| Item | Typical range in Los Altos |
|---|---|
| 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?
Most composition shingle replacements on a standard Los Altos ranch finish in 3-5 business days, though Heritage Tree Ordinance access restrictions or decking replacement can extend this. Call (669) 215-4852 to schedule your free estimate.
Will you match my existing shingles if only part of the roof needs repair?
We stock GAF and Owens Corning color-matched tabs for the most common Los Altos vintage, and when a line is discontinued we photograph the existing material and source the closest current equivalent with your approval. Call (669) 215-4852 for an exact quote - estimates are free.
Windows & Doors in Los Altos
Original Los Altos ranch homes were built with single-pane aluminum sliders and hollow-core entry doors that conduct heat and leak air at the weatherstripping, while the city’s microclimate of hot, dry summers and cool, wet winters creates expansion-contraction cycles that destroy seals. Our Windows & Doors teams specify vinyl-framed or fiberglass units with low-E coatings and argon fill appropriate for the solar heat gain on south-facing Los Altos lots.
Window Replacement
Signs you need it
Condensation between double-pane glass, operable sashes that no longer seal when locked, and visible UV damage to interior flooring near south-facing walls indicate the glazing assembly has failed.
What it costs in Los Altos
Window replacement in Los Altos ranges from $4,500-$15,000 for a full-home package, with per-opening pricing varying by frame material, glazing specification, and whether the original aluminum frame requires structural adaptation.
How we do it
We measure each rough opening for square and level, remove the existing unit without disturbing stucco or interior trim where possible, install the new window with proper flashing integration, and foam-seal the perimeter before trim restoration.
Impact Windows & Doors
Signs you need it
Large picture windows on wind-exposed Los Altos hillsides, homes near construction zones with flying debris risk, or owners seeking the security and noise-reduction benefits of laminated glazing are the primary drivers.
What it costs in Los Altos
Impact window installation in Los Altos runs $8,000-$25,000 for a full-home specification, reflecting the laminated glass interlayer and reinforced frame hardware required for missile-impact rating.
How we do it
We specify impact-rated units with documented Miami-Dade or AAMA certification, install with structural anchoring to resist design wind pressures, and provide the written warranty and photo record specified under Clause 1 of The Haven Standard.
What Windows & Doors Costs in Los Altos
| Item | Typical range in Los Altos |
|---|---|
| Window Replacement | $4,500-$15,000 |
| Impact Window Installation | $8,000-$25,000 |
Do I need permits for window replacement in Los Altos?
Los Altos requires permits for any window that alters the rough opening size or changes the egress compliance of a bedroom; like-for-like replacements in existing openings often do not. Call (669) 215-4852 and we will verify permit requirements during your free estimate.
Can you match the stucco finish after window installation?
Our crews include finish repair to the specified stucco texture and color match as part of the written scope; we photograph the existing wall condition before removal to ensure the patch is documented and verifiable. Call (669) 215-4852 for an exact quote - estimates are free.
Fence Installation in Los Altos
Los Altos fence installation must navigate the Heritage Tree Ordinance root zones, sloped lots common in the foothill areas, and HOA design guidelines in neighborhoods like Rancho and South Los Altos that restrict materials and heights. Our Fence Installation crews survey the lot line, verify utility clearances, and specify posts set below the frost line in concrete to resist the soil movement that adobe clay produces through wet-dry cycles.
Vinyl Fence
Signs you need it
HOA-mandated white or tan perimeter fencing, pool enclosures requiring a non-climbable barrier, or homeowners seeking a maintenance-free alternative to cedar in Los Altos’s high-UV exposure are typical drivers.
What it costs in Los Altos
Vinyl fence installation in Los Altos ranges from $3,500-$9,000 depending on linear footage, panel height, and whether the lot slope requires stepped or racked installation.
How we do it
We lay out the run with post spacing engineered for wind load, auger holes below the clay shrink-swell zone, set posts in concrete with temporary bracing, then hang panels with stainless steel fasteners and a written 365-Day Done Right Promise.
Aluminum Fence
Signs you need it
Ornamental perimeter fencing on view-oriented Los Altos lots where solid barriers would obstruct sightlines, or pool enclosures requiring code-compliant 48-inch height with decorative picket profiles.
What it costs in Los Altos
Aluminum fence installation in Los Altos typically runs $4,000-$10,000, with powder-coat color and spear-top or flat-top styling as the primary price variables.
How we do it
We specify extruded aluminum rail systems with welded pickets, set posts in concrete piers engineered for lateral soil movement, and deliver the documented photo record and written warranty before final payment.
What Fence Installation Costs in Los Altos
| Item | Typical range in Los Altos |
|---|---|
| Vinyl Fence Installation | $3,500-$9,000 |
| Aluminum Fence Installation | $4,000-$10,000 |
Does Los Altos require permits for fence installation?
Los Altos requires permits for fences over 6 feet or any fence within a front setback; corner lots have additional sight-triangle restrictions we verify before layout. Call (669) 215-4852 for a free estimate and permit check.
How do you handle tree roots when installing a fence in Los Altos?
We identify protected specimens and their root zones before staking the line, and when a Heritage Tree requires post relocation we document the revision with photos and a signed change order before proceeding. Call (669) 215-4852 for an exact quote - estimates are free.
Driveway & Pavers in Los Altos
Original Los Altos driveways are narrow concrete strips or aging asphalt poured for single vehicles in the 1950s-1960s, inadequate for modern multi-car households and cracked by adobe clay soil movement. Our Driveway & Pavers crews engineer subgrade preparation with aggregate base and edge restraint systems that accommodate the 2-4 inches of seasonal soil swell-shrink common to Santa Clara Valley clay.
Paver Driveways
Signs you need it
Spiderweb cracking across an original concrete driveway, standing water after rain indicating subgrade settlement, or homeowners seeking the permeability and design flexibility that interlocking concrete pavers provide on Los Altos’s tight lots.
What it costs in Los Altos
Paver driveway installation in Los Altos ranges from $7,000-$18,000 depending on square footage, paver brand and pattern complexity, and whether the clay subgrade requires geotextile stabilization or additional base depth.
How we do it
We excavate to engineered depth, install compacted aggregate base in lifts, lay bedding sand, set Unilock or Techo-Bloc pavers to pattern with edge restraint, sweep polymeric sand into joints, and compact with a plate vibrator before final wash and photo documentation.
Concrete Driveways & Concrete Work
Signs you need it
Driveway slabs shifted into trip hazards by soil heave, spalling surface from decades of freeze-thaw cycling on north exposures, or expansion joints that have failed and allowed adjacent panels to collide and crack.
What it costs in Los Altos
Concrete driveway installation in Los Altos runs $4,500-$12,000 for standard broom-finish replacement, with stamped or colored finishes adding to the base price.
How we do it
We remove the failed slab, compact the clay subgrade with moisture control, place welded wire mesh or rebar per engineering, pour 4-inch minimum thickness with control joints at calculated spacing, and finish to the specified texture with a written warranty.
What Driveway & Pavers Costs in Los Altos
| Item | Typical range in Los Altos |
|---|---|
| Paver Driveway Installation | $7,000-$18,000 |
| Concrete Driveway Installation | $4,500-$12,000 |
| Asphalt Driveway Paving | $3,500-$9,000 |
How long before I can drive on a new paver driveway in Los Altos?
Polymeric sand requires 24 hours to set without vehicle traffic, and we recommend 72 hours before regular use; the written completion documentation specifies exact cure times for your installation. Call (669) 215-4852 to schedule your free estimate.
Will pavers shift on Los Altos’s clay soils?
Proper base depth, geotextile separation, and edge restraint prevent shifting on expansive clay; we engineer for the local soil conditions and document base preparation with photos before pavers are laid. Call (669) 215-4852 for an exact quote - estimates are free.
