AfterConstruction in Los Altos, CA
Roofing in Los Altos runs $400 for targeted repairs up to $20,000 for a full replacement on the post-war ranch homes that dominate this foothill city, with western neighborhoods seeing accelerated wear from heavier winter rainfall off the Santa Cruz Mountains. We dispatch crews from our Bay Area office and coordinate projects across Los Altos’s unincorporated county pockets and city-proper zones, where permit requirements can shift block by block. Call (669) 271-8644 for a written estimate before any work starts.
Why Los Altos Homes Are Different
Los Altos sits at a construction inflection point that few Bay Area cities match. The core housing stock is single-story post-WWII ranch homes built 1950 to 1975, many with original slab or cripple-wall foundations, outdated 100-amp Federal Pacific or Zinsco electrical panels, and galvanized supply plumbing. When tech-wealth buyers purchase these properties on 10,000 to 15,000 square foot lots, the typical project is not a kitchen refresh but a full teardown or whole-house remodel into a 4,000 to 6,000 square foot custom build.
This workflow triggers Los Altos’s Design Review Board, a layer of architectural scrutiny that neighboring Mountain View and Sunnyvale do not impose. New or substantially remodeled homes must meet specific massing, setback, and neighborhood-compatibility standards. Contractors who have not navigated this board see plans kicked back, adding months. We maintain pre-approved architectural relationships and submit conceptual renderings before pulling demo permits.
The terrain matters too. Western Los Altos neighborhoods receive meaningfully more winter rainfall and hillside groundwater pressure than flat Silicon Valley cities to the east. Drainage, retaining walls, and proper grading are critical on any teardown-rebuild. Hillside-adjacent sites can surprise with expansive clay soils that shift during the wet season, making geotechnical assessment a line item we flag early rather than discover mid-project.
Our Main Los Altos Services
Los Altos homeowners call us most often for whole-room transformations and major additions that match the city’s mansionization cycle. These three trades have dedicated Los Altos pages with full pricing and local permit guidance.
Kitchen Remodeling in Los Altos
Kitchen remodels in Los Altos typically start at $14,000 and run to $45,000 for full teardowns with custom cabinetry and stone surfaces. The original galley layouts in 1960s ranch homes rarely suit contemporary open-plan living, so we see frequent wall removals requiring beam engineering and permit coordination with Santa Clara County or the city. We quote Cambria or Caesarstone surfaces, KraftMaid or Wellborn cabinetry, and a written scope that includes structural, electrical, and finish work as discrete line items. Kitchen Remodeling in Los Altos covers our full process, from as-built documentation to final punch.
Bathroom Remodeling in Los Altos
Bathroom projects in Los Altos range from $5,000 for a small bathroom refresh to $28,000 for a master suite with walk-in shower and heated floors. Original bathrooms in this housing stock often contain galvanized supply lines, inadequate venting, and no GFCI protection. We replace the wet-area substrate with cement board or foam-core waterproofing systems, upgrade electrical to code, and specify Kohler or Toto fixtures with documented performance specs. Every quote lists permit costs separately so homeowners see where their money goes. Bathroom Remodeling in Los Altos details our full scope and timeline.
Home Additions & ADU in Los Altos
Home additions in Los Altos run $45,000 to $130,000; detached ADU construction ranges from $90,000 to $220,000. The generous lot sizes here make ADUs and second-story additions feasible in ways they are not in denser Peninsula cities, but the Design Review Board’s massing and compatibility standards add a planning phase that less experienced contractors underestimate. We prepare conceptual renderings for pre-submission, coordinate geotechnical reports for hillside lots, and quote the project as a flat price with permit costs itemized. Home Additions & ADU in Los Altos explains our Design Review navigation and fixed-price structure.

Before
AfterRoofing in Los Altos
Roofing in Los Altos means working on low-slope ranch roofs with original cedar shake or early asphalt shingle layers, often with inadequate ventilation for the heavier rainfall that sweeps off the Santa Cruz Mountain foothills into western neighborhoods. The Mediterranean dry season allows long installation windows, but winter moisture intrusion on these aging substrates drives our repair volume from November through March. We document every roof with photos before quoting, and our Roofing hub explains the full trade scope.
Roof Repair
Signs you need it
Water stains on ceiling drywall, granule loss visible in gutters, or lifted shingles along the rake edges after winter storms.
What it costs in Los Altos
Roof repair in Los Altos typically runs $400 to $1,800 depending on whether we are replacing a few asphalt shingles, resealing valley flashing, or addressing localized wood rot in the roof deck.
How we do it
We photograph the damage from the ridge and the attic, remove the compromised material to sound deck, install matching shingles or membrane with ice-and-water shield at valleys, and deliver a photo record of the completed repair with a written warranty.
Roof Replacement & Installation
Signs you need it
Two or more layers of existing roofing, widespread curling or cracking, or a roof age exceeding 25 years with active leaks.
What it costs in Los Altos
A full roof replacement in Los Altos ranges from $8,000 to $20,000 for asphalt architectural shingles, with the upper end reflecting steep pitches, multiple dormers, or deck replacement.
How we do it
We strip to bare deck, inspect and replace compromised sheathing, install synthetic underlayment and GAF or Owens Corning shingles with proper ridge venting, and pass municipal inspection before final payment.

| Metal Roof Installation | $15,000 - $40,000 |
How long does a roof replacement take in Los Altos?

Do you handle permits for roofing in Los Altos?
Yes, we pull all roofing permits and schedule inspections; Los Altos and unincorporated county pockets have different requirements, and we file correctly the first time. Call (669) 271-8644 to confirm your property’s jurisdiction.
Windows & Doors in Los Altos
Windows and doors in Los Altos must address two realities: original aluminum single-pane windows in 1960s ranch homes that bleed heat and admit noise, and the Design Review Board’s scrutiny of any exterior modification that changes massing or visible materials. Western neighborhoods also face heavier winter wind-driven rain, making proper flashing and sill pan installation non-negotiable. We specify products that meet both performance and aesthetic requirements, and our Windows & Doors hub lists our full brand inventory.
Window Replacement
Signs you need it
Condensation between double-pane glass, drafts around sash perimeters, or difficulty operating original aluminum sliders that have warped in their tracks.
What it costs in Los Altos
Window replacement in Los Altos ranges from $4,500 to $15,000 for a typical ranch home, with the upper end reflecting custom sizing, egress requirements, or Design Review-mandated divided-light patterns.
How we do it
We measure each rough opening, specify vinyl or fiberglass units with low-E coatings and argon fill, install with integral flanged nailing and self-adhered membrane at sills, and deliver a photo record of the completed installation.
Impact Windows & Doors
Signs you need it
Large west-facing glass areas in hillside homes that experience wind-borne debris, or homeowners seeking noise reduction from Foothill Expressway corridor traffic.
What it costs in Los Altos
Impact window installation in Los Altos runs $8,000 to $25,000, reflecting laminated glass, reinforced frames, and the structural anchoring required for large openings.
How we do it
We engineer for wind load and positive pressure, install laminated glass in reinforced vinyl or aluminum frames with structural anchoring to the stud, and document the installation for insurance and resale disclosure.
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 Design Review approval for window replacement in Los Altos?
Sometimes. Visible exterior changes to window style, size, or material trigger Design Review; like-for-like replacements in the same opening typically do not. We review your property’s zoning before quoting and flag any approval timeline in the written scope.
What window brands do you install in Los Altos?
We stock and install across multiple performance tiers, from vinyl to aluminum-clad wood, with low-E and argon specifications documented in every quote. Call (669) 271-8644 for brand-specific pricing and lead times.
Fence Installation in Los Altos
Fence installation in Los Altos operates within strict parameters: front-yard height limits, Design Review compatibility for visible street fencing, and the need for proper drainage on sloped lots that receive heavier foothill rainfall. Many properties back onto open space or creek corridors, requiring wildlife-friendly designs or Santa Clara Valley Water District setback compliance. We navigate these layers before breaking ground, and our Fence Installation hub explains material specifications and warranty terms.
Vinyl Fence
Signs you need it
Rotting wood privacy panels, recurring maintenance on painted board fences, or a desire for a clean perimeter that does not require staining or sealing.
What it costs in Los Altos
Vinyl fence installation in Los Altos ranges from $3,500 to $9,000 for a typical backyard perimeter, with height and post-depth requirements adjusted for hillside wind load.
How we do it
We lay out the run with post spacing at eight feet on center, auger holes to 36 inches with gravel drainage base, set posts in concrete, and install tongue-and-groove panels with aluminum rail reinforcement.
Aluminum Fence
Signs you need it
Corroded wrought iron, a need for pool-code compliance with visibility, or a front-yard boundary that must meet Design Review’s open and decorative standards.
What it costs in Los Altos
Aluminum fence installation in Los Altos runs $4,000 to $10,000, with powder-coated finishes and spear-top or flat-top styles priced per linear foot with gates itemized separately.
How we do it
We set posts in concrete with slope-racked panels for grade changes, install self-closing hinges and magnetic latches on gates, and deliver a photo record of post-depth and concrete cure before final walkthrough.
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 |
Do I need a permit for a fence in Los Altos?
Front-yard fences over three feet and side or rear fences over six feet require a permit; corner lots have additional sight-triangle restrictions. We verify your property’s zoning and include permit costs in the written quote.
How long does fence installation take in Los Altos?
A typical residential fence takes two to four days after permit approval, with an additional day for hillside grading or drainage work. Call (669) 271-8644 for a timeline tied to your specific lot conditions.
Driveway & Pavers in Los Altos
Driveway and paver work in Los Altos must account for expansive clay soils in hillside-adjacent neighborhoods, heavier winter rainfall that undermines improperly compacted bases, and the Design Review Board’s interest in hardscape materials that complement the streetscape. Original concrete driveways from the 1960s are often cracked, stained, or pitched toward foundations without adequate drainage. We engineer for soil conditions and water management, and our Driveway & Pavers hub details base construction and material specifications.
Paver Driveways
Signs you need it
Spiderweb cracking in original concrete, pooling after rain, or a desire for permeable surfacing that reduces runoff on large Los Altos lots subject to drainage review.
What it costs in Los Altos
Paver driveway installation in Los Altos ranges from $7,000 to $18,000, with Belgard or Techo-Bloc permeable pavers at the upper end and standard interlocking concrete at the entry point.
How we do it
We excavate to eight inches, install geotextile and compacted aggregate base in lifts, set edge restraints on concrete haunching, lay pavers in herringbone or running bond, and sweep polymeric sand into joints with plate compaction.
Concrete Driveways & Concrete Work
Signs you need it
Significant cracking with vertical displacement, spalling from freeze-thaw or de-icing salts, or a driveway pitched toward the garage or foundation without a drainage swale.
What it costs in Los Altos
Concrete driveway installation in Los Altos runs $4,500 to $12,000 for standard four-inch slump with rebar reinforcement, with the upper end reflecting larger ranch-lot frontages or stamped and colored finishes.
How we do it
We form to pitch away from structures, place and finish with control joints at proper spacing, saw-cut expansion joints within 24 hours, and cure with moisture-retaining blankets for seven days before vehicle loading.
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 |
Do pavers hold up on Los Altos clay soils?
Yes, with proper base engineering. We excavate to eight inches, install geotextile separation fabric, and compact aggregate in lifts to prevent settling on expansive soils. The written quote specifies base depth and material by line item.
Can you match existing hardscape for a partial driveway replacement?
We source from current manufacturer lines and can often approximate discontinued colors; exact matches on decades-old concrete are not guaranteed. Call (669) 271-8644 for a site review and sample comparison.
