AfterConstruction in Sunnyvale, CA
Roofing, window replacement, fence installation, and driveway work in Sunnyvale run $400 to $40,000 depending on scope, with most homeowners receiving a written quote the same day we inspect. The city’s 1950s-1970s ranch housing stock, marine-layer moisture, and high land values create construction conditions unlike neighboring Mountain View or Santa Clara. Call (669) 259-1843 to schedule your free estimate.
Why Sunnyvale Homes Are Different
Sunnyvale sits at the dead center of Silicon Valley’s teardown-rebuild cycle: lots routinely appraise above $1.5M at land value alone, making full demolition and custom new construction on 1950s-60s ranch-home lots far more common here than anywhere 20 miles away. Every construction company operating in Sunnyvale must be fluent in the city’s specific plan-check process, Title 24 energy compliance, and ADU-by-right permitting rules - demand for which has made Sunnyvale one of the highest-volume ADU jurisdictions in California.
The dominant housing stock is post-WWII single-story ranch homes built 1950-1975, predominantly wood-frame on slab or shallow perimeter foundations. Many lack adequate cripple-wall bracing or anchor bolts per modern seismic standards. Because lot values alone exceed $1M in most neighborhoods, these homes are as often scraped entirely as they are renovated, shifting contractor workload heavily toward new infill construction on tight 6,000-7,500 sq ft lots.
Sunnyvale’s mild Mediterranean climate means no freeze-related delays, but the winter wet season (November-March) compresses grading, foundation, and framing schedules. The Bay’s marine layer keeps soil moisture high enough that compaction testing frequently fails in early spring, a recurring issue on the flat, alluvial valley floor underlying most of the city.
Decades of semiconductor and defense manufacturing left multiple EPA Superfund plumes beneath Sunnyvale neighborhoods - particularly around the Middlefield-Ellis-Whisman corridor - meaning excavation and grading crews must routinely account for soil vapor intrusion protocols, restricted disposal of contaminated spoils, and city-required vapor barriers on new slabs. This site-condition reality blindsides contractors who’ve only worked in neighboring Mountain View or Cupertino.
Our Main Sunnyvale Services
Most Sunnyvale homeowners who call us start with kitchen remodeling, bathroom remodeling, or home additions and ADUs - the three trades that dominate this market given the city’s teardown-rebuild economics and ADU-by-right rules.
Kitchen Remodeling in Sunnyvale
Kitchen remodeling in Sunnyvale often means reconfiguring the galley or L-shaped layouts common in 1960s ranch homes to open-concept plans that match current resale expectations. We handle full demolition, structural wall assessment, electrical and plumbing rerouting, cabinet and countertop installation, and final inspection. Because many Sunnyvale kitchens sit on slabs with no crawl space, plumbing relocations require core drilling and careful coordination with the city’s plan-check timeline. Kitchen Remodeling in Sunnyvale covers our full process, material brands, and written pricing structure.
Bathroom Remodeling in Sunnyvale
Bathroom remodeling in Sunnyvale addresses the small footprint and vented-soffit construction typical of post-war ranches, where moisture management was an afterthought. We replace subfloors damaged by decades of steam penetration, install curbless showers where aging-in-place is a priority, and specify exhaust systems that actually move air through the original soffit vents. Every bathroom quote includes a written scope, a photo record of pre-existing conditions, and the 365-Day Done Right Promise printed on the contract. Bathroom Remodeling in Sunnyvale details our flat-price process.
Home Additions & ADU in Sunnyvale
Home additions and ADU construction in Sunnyvale benefit from some of California’s most permissive by-right zoning, but the advantage disappears if your contractor stumbles on Title 24 energy calculations, fire separation requirements, or the city’s separate utility connection fees. We prepare the full plan set, coordinate the Sunnyvale plan-check submittal, and quote the project as a flat price before any permit is pulled. Our documented photo record tracks every phase, from foundation through final inspection. Home Additions & ADU in Sunnyvale explains our ADU-specific workflow.

AfterRoofing in Sunnyvale
Most Sunnyvale roofs were last replaced in the 1990s or early 2000s, meaning the dominant installed base is 20-year dimensional shingle now at end of life. The marine layer deposits salt and moisture that accelerate granule loss and accelerate corrosion on flashing, particularly on low-slope sections where drainage is already marginal. Our Roofing crews inspect every roof with a documented photo record, deliver a written quote before any work starts, and back the result with the 365-Day Done Right Promise.
Roof Repair
Signs you need it
Water stains on ceiling drywall, granules collecting in gutters, or lifted shingles along the rake edges after winter wind events.
What it costs in Sunnyvale
Roof repair in Sunnyvale typically runs $400-$1,800 depending on whether we’re replacing a few shingles, re-flashing a vent penetration, or patching a localized leak in the underlayment.
How we do it
We photograph the damage from the ridge and the deck, remove the affected shingles to inspect the underlayment condition, replace any compromised decking, install new ice-and-water shield where the original has degraded, and re-shingle with a color-matched bundle.
Roof Replacement & Installation
Signs you need it
Curling or cupping across more than 30% of the field, visible daylight through the attic decking, or a roof age exceeding 22 years with two or more prior repair areas.
What it costs in Sunnyvale
Full roof replacement in Sunnyvale ranges from $8,000-$20,000 for standard architectural shingle on a typical 1,800 sq ft ranch, with tile or metal systems at the higher end.
How we do it
We strip to bare deck, replace any rotted sheathing identified in the photo record, install synthetic underlayment and drip edge, apply GAF or Owens Corning shingles per the written spec, and schedule the city inspection before final payment.
What Roofing Costs in Sunnyvale

|---|---|
| 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 Sunnyvale?
Most residential roof replacements on Sunnyvale’s single-story ranches take two to three working days, with an additional day if decking replacement exceeds 10% of the surface. Call (669) 259-1843 for an exact quote - estimates are free.
Do you handle Title 24 cool roof requirements in Sunnyvale?
Yes - Sunnyvale enforces Title 24 cool roof standards on all re-roofing projects, and we specify compliant shingles from GAF and Owens Corning with documented SRI values. The compliance certificate is included in your project file at no additional charge. Call (669) 259-1843 for an exact quote - estimates are free.
Windows & Doors in Sunnyvale
The original windows in Sunnyvale’s 1950s-1975 housing stock are predominantly single-pane aluminum or wood sash with failed weatherstripping, costing homeowners measurable HVAC load in a climate where air conditioning run hours have climbed steadily. Our Windows & Doors service replaces these with Title 24-compliant vinyl or fiberglass units, quotes the full job in writing before ordering, and documents the installation with the photo record included as standard.
Window Replacement
Signs you need it
Condensation between double-pane glass, operable sashes that jam or fall closed, or visible daylight around the frame perimeter when closed.
What it costs in Sunnyvale
Window replacement in Sunnyvale runs $4,500-$15,000 for a typical ranch home, with per-opening costs driven by size, egress requirements, and whether the original frame is retrofitted or fully replaced.
How we do it
We measure each opening to 1/8 inch, remove the old unit without disturbing interior trim where possible, install the new window with low-expansion foam and proper sill pan flashing, and verify operation and lock engagement before moving to the next opening.
Impact Windows & Doors
Signs you need it
Homeowner preference for security and noise reduction in high-traffic corridors like El Camino Real or Mathilda Avenue, or insurance requirements for homes in designated wind zones.
What it costs in Sunnyvale
Impact window installation in Sunnyvale ranges from $8,000-$25,000 depending on opening count, frame material, and whether laminated glass is specified for the full perimeter or select elevations.
How we do it
We specify laminated impact-rated glass with reinforced frames, install with structural fastening per the manufacturer’s Miami-Dade or AAMA certification, and provide the documentation required for insurance premium credits.
What Windows & Doors Costs in Sunnyvale
| Item | Typical range in Sunnyvale |
|---|---|
| Window Replacement | $4,500 - $15,000 |
| Impact Window Installation | $8,000 - $25,000 |
Do I need permits to replace windows in Sunnyvale?
Sunnyvale requires permits for window replacement when the opening size changes, when egress requirements are affected, or when the wall is part of a fire-rated assembly; we pull the permit and schedule inspection as part of the written scope. Call (669) 259-1843 for an exact quote - estimates are free.
How do I know if my old windows are worth repairing versus replacing?
Single-pane windows with intact frames and no rot can sometimes be retrofitted with exterior storm panels or interior inserts, but the payback on full replacement with dual-pane low-E units is typically under eight years in Sunnyvale’s cooling-dominated climate. Call (669) 259-1843 for an exact quote - estimates are free.
Fence Installation in Sunnyvale
Sunnyvale’s tight 6,000-7,500 sq ft lots and high property values make fence installation as much a privacy and security calculation as a boundary marker, with many homeowners replacing 40-year-old redwood board fences that have rotted at the post line due to marine-layer moisture retention. Our Fence Installation service specifies pressure-treated or galvanized posts, quotes material and labor as a flat written price, and documents the layout and post-depth with the photo record delivered at project close.
Vinyl Fence
Signs you need it
Existing wood fence shows fungal decay at ground contact, homeowner wants zero maintenance and a clean sight line along property lines shared with neighbors.
What it costs in Sunnyvale
Vinyl fence installation in Sunnyvale ranges from $3,500-$9,000 for a typical 150-linear-foot perimeter, with price driven by panel height, post cap style, and whether Bufftech or ActiveYards product is specified.
How we do it
We lay out the run with string line, auger post holes to 24-inch depth in Sunnyvale’s alluvial soil, set posts in gravel and concrete, hang pre-routed vinyl panels, and verify plumb and grade before backfill.
Aluminum Fence
Signs you need it
Pool enclosure required by Sunnyvale building code, or decorative perimeter fencing where visibility and corrosion resistance matter more than privacy.
What it costs in Sunnyvale
Aluminum fence installation in Sunnyvale runs $4,000-$10,000 depending on height, picket style, and whether Jerith or Ameristar ornamental systems are specified.
How we do it
We verify property lines and utility clearances, set aluminum posts with surface-mounted or core-drilled bases depending on substrate, hang welded panels with concealed fasteners, and apply the manufacturer’s powder-coat touch-up at any field-cut locations.
What Fence Installation Costs in Sunnyvale
| Item | Typical range in Sunnyvale |
|---|---|
| Vinyl Fence Installation | $3,500 - $9,000 |
| Aluminum Fence Installation | $4,000 - $10,000 |
Does Sunnyvale require a permit to install a fence?
Sunnyvale requires permits for fences over 6 feet in height, for any fence along a front property line, and for all pool enclosures; we verify your zoning, pull the permit, and schedule inspection before final payment. Call (669) 259-1843 for an exact quote - estimates are free.
How long does a vinyl fence last in Sunnyvale’s climate?
Quality vinyl fencing in Sunnyvale’s mild, non-freezing climate typically exceeds 25 years with no painting or staining, though UV exposure on south-facing elevations can cause gradual fading that manufacturers address with titanium-dioxide formulations. Call (669) 259-1843 for an exact quote - estimates are free.
Driveway & Pavers in Sunnyvale
The original driveways in Sunnyvale’s 1950s-1975 subdivisions are predominantly 4-inch unreinforced concrete now exhibiting longitudinal cracking, spalling from decades of marine-layer moisture cycling, and settlement where the alluvial subgrade was inadequately compacted. Our Driveway & Pavers service evaluates the base condition with compaction testing, quotes replacement or overlay options as a flat written price, and documents the excavation and base prep with the photo record standard on every project.
Paver Driveways
Signs you need it
Existing concrete is cracked across more than 40% of the surface, homeowner wants permeable or decorative hardscape that complements a renovated front elevation.
What it costs in Sunnyvale
Paver driveway installation in Sunnyvale ranges from $7,000-$18,000 for a typical two-car apron, with Belgard or Techo-Bloc product lines and permeable base systems at the higher end.
How we do it
We remove the existing pavement to 8-inch depth, test and recompact the native base or import Class 2 aggregate where the alluvial soil fails, install bedding sand and edge restraint, lay pavers to pattern with 1/8-inch joint spacing, and sweep polymeric sand before vibrating to lock.
Concrete Driveways & Concrete Work
Signs you need it
Surface scaling exposes aggregate, control joints have faulted more than 1/2 inch, or the slab has settled toward the garage creating a trip hazard and drainage reversal.
What it costs in Sunnyvale
Concrete driveway installation in Sunnyvale runs $4,500-$12,000 depending on square footage, reinforcement with wire mesh or rebar, and whether a broom or exposed-aggregate finish is specified.
How we do it
We saw-cut and remove the failed slab, test subgrade compaction and add base rock where the alluvial soil is loose, form and pour 4-inch minimum thickness with control joints at 10-foot intervals, and cure with membrane compound for seven days before vehicle loading.
What Driveway & Pavers Costs in Sunnyvale
| Item | Typical range in Sunnyvale |
|---|---|
| Paver Driveway Installation | $7,000 - $18,000 |
| Concrete Driveway Installation | $4,500 - $12,000 |
| Asphalt Driveway Paving | $3,500 - $9,000 |
Can you install pavers over my existing concrete driveway?
Pavers can be thin-set over sound concrete in Sunnyvale only if the existing slab has no settlement, cracking, or drainage issues; we inspect with a sounding hammer and specify full removal where the substrate is compromised. Call (669) 259-1843 for an exact quote - estimates are free.
How does Sunnyvale’s soil affect driveway longevity?
Sunnyvale’s flat alluvial valley floor contains loose sandy loams that settle under load if not compacted to 95% modified Proctor density; we test every excavation and import engineered fill where native soils fail, which is why our paver and concrete installations include a written base specification. Call (669) 259-1843 for an exact quote - estimates are free.
