AfterConstruction in Los Altos, CA
Roofing in Los Altos runs $8,000-$20,000 for a full replacement, with most repairs landing between $400 and $1,800, because the 1950s-1970s housing stock and Santa Clara Valley clay soils create distinct wear patterns that differ from neighboring Peninsula cities. We quote every job with a flat written price before work starts, and our crews serve Los Altos from our San Francisco Bay Area dispatch office. Call (831) 704-1211 for a free estimate.
Why Los Altos Homes Are Different
Los Altos sits on some of the most expensive dirt in the country, and that land value shapes every construction decision. The core housing stock is 1950s-1970s ranch and split-level homes on quarter-acre lots, most built with slab or post-and-pier foundations that predate current California Building Code seismic standards. Proximity to the San Andreas Fault, roughly five miles west, means Santa Clara County enforces moment frames, hold-downs, and shear-wall schedules that add material cost and engineering complexity compared to work in less fault-adjacent cities.
The Santa Clara Valley’s expansive adobe clay soils swell in winter rains and shrink through the dry summer, cracking slabs and shifting post-and-pier foundations over decades. Any permitted remodel in Los Altos almost certainly includes structural upgrade line items. And because the city is essentially built out, “new construction” typically means a permitted demolition followed by a custom rebuild subject to Los Altos’s design review and strict floor-area-ratio limits.
The Heritage Tree Ordinance is the wildcard that catches unprepared contractors. Mature coast live oaks blanket residential lots, and the ordinance legally restricts grading, excavation, and trenching within protected root zones. A separate tree permit is required before breaking ground; skip it, and a single unpermitted auger hole within a heritage oak’s dripline can trigger a stop-work order, remediation bond, and city fines that push projects past the rainy season, when clay soils make foundation work unpredictable. Veteran crews walk every lot with an ISA-certified arborist before permit drawings go in.
Our Main Los Altos Services
Los Altos homeowners call us most often for whole-home transformations and footprint expansion. Here’s what those projects involve locally.
Kitchen Remodeling in Los Altos
Kitchen remodels in Los Altos typically mean gutting a 1960s galley or U-shaped layout and reworking it for modern flow, often with structural upgrades to meet current seismic code. We see a lot of load-bearing wall removals to open into dining areas, which requires beam sizing and permit drawings that account for the county’s shear-wall requirements. Every quote includes a written scope and flat price before demolition starts. Kitchen Remodeling in Los Altos
Bathroom Remodeling in Los Altos
Bathroom work in Los Altos runs into the same era-specific issues: original cast-iron drains, inadequate venting, and subfloors that have settled with the clay soil cycle. We replace plumbing to current code, reinforce floors where tile or stone will add load, and document substrate conditions with photos before any fixture goes in. Bathroom Remodeling in Los Altos
Home Additions & ADU in Los Altos
Additions and ADUs in Los Altos face the city’s strict floor-area-ratio limits and the heritage tree review, often on lots where the only buildable zone is already occupied by a mature oak’s protected root zone. We coordinate arborist reports with structural and civil drawings so the permit package moves through planning without revision cycles. Home Additions & ADU in Los Altos

AfterRoofing in Los Altos
Most Los Altos roofs are original 20-year three-tab asphalt shingles installed in the 1970s or 1980s, now past or near end of service life, and the clay soil settlement shifts fascia and ridge lines in ways that accelerate wear at valleys and penetrations. Our Roofing crews start every Los Altos job with a documented photo survey of substrate condition, layer count, and fastener schedule so the written quote reflects what we found, not what we guessed.
Roof Repair
Signs you need it
Water stains on ceiling drywall, granule loss in gutters, or lifted shingles at the rake edges after Santa Clara Valley wind events.
What it costs in Los Altos
Roof repair in Los Altos typically runs $400-$1,800 depending on whether we’re replacing a few wind-damaged shingles or reworking valley flashing where clay soil settlement has opened a seam.
How we do it
We remove damaged material to the deck, photograph the substrate condition, install matching shingles or custom-bent flashing, and provide a written photo record of the repair area before and after.
Roof Replacement & Installation
Signs you need it
Multiple leak points, visible sagging at the ridge, or shingles that have curled and lost granule coverage across more than 30% of the field.
What it costs in Los Altos
Roof replacement in Los Altos ranges from $8,000-$20,000 for standard asphalt architectural shingles, with metal and tile systems running higher due to seismic strapping and underlayment requirements.
How we do it
We strip to bare deck, replace compromised sheathing, install ice-and-water shield at valleys and penetrations per Santa Clara County wind uplift standards, and finish with a documented final inspection photo set.
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 asphalt shingle replacements on a standard Los Altos ranch take three to five working days, though heritage tree access restrictions or seismic hold-down details can add a day or two. We build that into the written schedule before work starts. Call (831) 704-1211 for a timeline on your specific roof.
Will a new roof in Los Altos need structural upgrades?
Often yes, if the original structure predates current seismic code. We inspect rafter ties, ridge beam connections, and shear-wall continuity during our survey, and any required upgrades are itemized in the written quote, not discovered mid-project. Call (831) 704-1211 for a free roof assessment.
Windows & Doors in Los Altos
The original single-pane aluminum windows in Los Altos’s 1950s-1970s housing stock conduct heat and cold at rates that modern codes won’t permit in new construction, and many frames have corroded at the weep screed or settled out of square as the clay soil cycled beneath the slab. Our Windows & Doors team measures every opening to 1/8-inch tolerance because replacement units ordered to “standard” sizes leave gaps that caulk can’t fix permanently.
Window Replacement
Signs you need it
Condensation between double-pane glass, operable sashes that stick or won’t lock, or visible frame corrosion at the sill where drainage has failed.
What it costs in Los Altos
Window replacement in Los Altos ranges from $4,500-$15,000 for a full-home retrofit depending on unit count, frame material, and whether seismic hold-down clips are required at the rough opening.
How we do it
We measure each opening after checking for square and level, order custom-sized units, install with proper sill pan flashing and insulation, and photograph the completed rough opening and finish trim for the project record.
Impact Windows & Doors
Signs you need it
Large south- or west-facing glass areas that overheat rooms, or hillside homes where Santa Clara County wind exposure maps require enhanced impact resistance.
What it costs in Los Altos
Impact window installation in Los Altos typically runs $8,000-$25,000 for a full-home package, reflecting laminated glass, reinforced frames, and the structural verification that Santa Clara County requires for enhanced wind-load zones.
How we do it
We verify the structural engineer’s wind-load calculations against the manufacturer’s test reports, install with structural screws at specified spacing, and provide the documentation package for final inspection.
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 replacement windows in Los Altos require permits?
Yes, Santa Clara County requires permits for window replacement when the opening size changes or when the home is in a seismic or wind-exposure zone, which covers most of Los Altos. We pull permits and schedule inspections as part of our standard scope. Call (831) 704-1211 for permit details on your project.
Can you match the style of original 1960s windows?
Yes, manufacturers like Andersen and Milgard offer period-appropriate divided-lite patterns in modern dual-pane packages that meet current energy code. We source samples before ordering so you see the exact sight lines. Call (831) 704-1211 to schedule a sample review.
Fence Installation in Los Altos
Los Altos fence work is shaped by two forces: the Heritage Tree Ordinance, which can prohibit post holes within protected root zones, and the city’s design review expectations for street-facing properties in established neighborhoods. Our Fence Installation crews verify arborist clearance before laying out a single post, because a stop-work order on a fence project delays the entire construction schedule.
Vinyl Fence
Signs you need it
Rotting wood boards that need annual staining, or a desire for a clean sight line that doesn’t require maintenance in Los Altos’s wet winters and dry summers.
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 we need to use surface-mount posts to avoid heritage tree root zones.
How we do it
We mark the layout with arborist-approved post locations, set posts in concrete or surface-mount on steel brackets where roots prohibit digging, hang panels with concealed fasteners, and photograph the completed run for the project record.
Aluminum Fence
Signs you need it
Pool enclosures that must meet Santa Clara County barrier code, or ornamental perimeter fencing where wrought iron would corrode in the clay soil’s moisture cycles.
What it costs in Los Altos
Aluminum fence installation in Los Altos typically runs $4,000-$10,000, with pool code packages at the higher end due to self-closing gates, latch heights, and the documentation required for final health department sign-off.
How we do it
We verify pool barrier code requirements with the county, set posts at specified spacing and depth, install gates with self-closing hinges and Magna-Latch or equivalent hardware, and provide the compliance certificate for your records.
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 |
Can you install a fence near a heritage tree in Los Altos?
Yes, but the post layout must be approved by an ISA-certified arborist and may require surface-mount brackets instead of dug posts. We coordinate that review before quoting so the price reflects the actual installation method. Call (831) 704-1211 for a fence layout assessment.
Does Los Altos require permits for fence replacement?
Street-facing fences over six feet and all pool barriers require permits; side and rear yard fences under six feet typically do not. We verify permit requirements during our site survey and include permit costs in the written quote if needed. Call (831) 704-1211 to confirm for your property.
Driveway & Pavers in Los Altos
The original concrete driveways in Los Altos’s 1950s-1970s subdivisions have cracked and settled with decades of clay soil expansion and contraction, and many are too narrow for modern vehicle widths or turn radii. Our Driveway & Pavers work starts with a soil compaction test because paving over unstable substrate guarantees failure within two seasons.
Paver Driveways
Signs you need it
Spider-web cracking across concrete that’s settled in multiple planes, or a driveway that ponds water toward the garage after rain because the clay soil has created a low spot.
What it costs in Los Altos
Paver driveway installation in Los Altos ranges from $7,000-$18,000 depending on square footage, base depth required for clay soil stability, and whether Belgard or Techo-Bloc product lines are specified.
How we do it
We excavate to engineered base depth, compact in lifts with a plate compactor and proof-roll verification, lay bedding sand, set pavers in the chosen pattern with edge restraint, and sweep polymeric sand into joints before final compaction.
Concrete Driveways & Concrete Work
Signs you need it
Driveway slabs that have separated at control joints, spalling surface layers from de-icing salt or age, or a need to widen the apron for modern vehicle access.
What it costs in Los Altos
Concrete driveway installation in Los Altos typically runs $4,500-$12,000, with clay soil conditions often requiring deeper sub-base and steel reinforcement that push toward the upper end of the range.
How we do it
We form to the new layout with proper slope away from structures, place rebar or mesh as engineered for soil conditions, pour with control joints at calculated spacing, and saw-cut expansion joints within 24 hours.
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?
We recommend 48-72 hours after final compaction and polymeric sand activation, though heavy vehicles should wait a full week for the base to settle through any residual clay soil moisture. We include specific cure guidance in your project closeout documentation. Call (831) 704-1211 for a paver driveway quote.
Will my driveway need special prep for Los Altos clay soil?
Almost always yes. We test compaction and moisture content at excavation, then specify base depth and geotextile reinforcement based on what we find, not a generic detail. That engineering is itemized in the written quote. Call (831) 704-1211 to schedule a soil assessment.

FAQs About Construction in Los Altos
Most Los Altos projects begin four to eight weeks after quote approval, with permit timelines and arborist reviews typically the controlling factors rather than crew availability. We build permit and review schedules into our project timeline so you know the real start date before signing. Call (831) 704-1211 to discuss your project’s schedule.
Yes, permit application, plan check response, and inspection scheduling are included in our standard scope for every Los Altos project. We pull building, plumbing, electrical, and separate tree permits as required, and we meet inspectors with the documented photo record that proves code-compliant work at each phase.
The Haven Standard is the operating system Rowan Construction Group has used since 2007: Clause 1 requires a flat written price before any work starts, and every change order must be signed before the changed work proceeds. That administrative discipline is why our projects finish within a few percent of the agreed price across 4,000-plus jobs. The 365-Day Done Right Promise is printed on every contract, backed by a terms page, not an asterisk.
