AfterConstruction in Sunnyvale, CA
Roofing and exterior construction in Sunnyvale runs into a unique problem: thousands of 1950s-70s ranch homes with original building materials now sitting on land worth $1.5M-$2M+, meaning every repair decision is weighed against a full rebuild or major addition. We handle Roofing, Windows & Doors, Fence Installation, and Driveway & Pavers across Sunnyvale’s aerospace-era neighborhoods, with crews dispatched from our San Francisco Bay Area office and a written price delivered before any work starts. Call (650) 560-7228 to schedule your free estimate.
Why Sunnyvale Homes Are Different
Sunnyvale’s construction market is defined by a collision of legacy and money that is unique in scale even within Silicon Valley: the city’s sprawling tracts of modest 1,000-1,500 sq ft ranch homes built in the 1950s-70s to house Lockheed Missiles and Space Company workers now sit on lots routinely assessed at $1.5M-$2M+, making full teardowns, ground-up rebuilds, and high-spec ADU additions the bread-and-butter project type - not the exception. No neighboring city has this same concentration of aerospace-era starter homes on tech-bubble land values generating premium, permit-heavy residential construction volume.
The dominant stock is single-story ranch homes built 1952-1975, typically with shallow perimeter or post-and-pier foundations, original single-pane aluminum windows, 100-amp panels, and in many cases aluminum branch wiring from the mid-1960s copper-price spike - all of which trigger required remediation scopes the moment a renovation permit is pulled. Western Sunnyvale, particularly neighborhoods closer to the Bay, sits on expansive Bay mud and alluvial fill that moves seasonally with moisture, requiring engineered slab or deep foundation designs that add meaningful cost over what the same home size would require in hillside cities like Los Altos Hills. Sunnyvale’s building department - one of the highest-volume permit offices in Santa Clara County - enforces Title 24 energy compliance and CalGreen documentation with particular rigor; contractors who work across the county learn quickly that Sunnyvale plan checkers will reject submittals that sail through neighboring cities’ offices.
Our Main Sunnyvale Services
Most Sunnyvale homeowners who call us start with interior renovations or ADU additions on their aerospace-era lots. Here’s what those projects involve locally.
Kitchen Remodeling in Sunnyvale
A kitchen remodel in Sunnyvale almost always uncovers aluminum branch wiring or a 100-amp panel that must be upgraded to 200-amp service before new appliances can be installed, which means the electrical scope is baked into our written quote from day one, not discovered mid-project. We spec KraftMaid and Wellborn cabinets, Cambria and Caesarstone countertops, and we pull the Title 24 compliance documentation Sunnyvale requires. Kitchen Remodeling in Sunnyvale runs from $14,000-$45,000 for a full remodel, with a written price before any demolition begins.
Bathroom Remodeling in Sunnyvale
Bathroom remodels in these Lockheed-era homes frequently reveal galvanized steel supply lines and original tile-on-mud shower pans that have exceeded their service life by decades. We replace with copper or PEX supply, install waterproofing membranes that meet current Santa Clara County standards, and document the substrate condition with photos before any fixture goes in. Bathroom Remodeling in Sunnyvale typically ranges $9,000-$28,000, with every line item priced in writing.
Home Additions & ADU in Sunnyvale
Lot sizes in the 6,000-8,000 sq ft range make detached ADUs structurally feasible and financially obvious in Sunnyvale, so nearly every remodel project now carries an ADU component. The Bay mud in western neighborhoods drives foundation costs higher than inland sites, and Sunnyvale’s plan checkers will scrutinize your fire separation and utility service calculations. Home Additions & ADU in Sunnyvale range from $45,000 for modest additions to $220,000 for full detached ADUs, with a flat written price and signed change orders for any modifications.

AfterRoofing in Sunnyvale
Sunnyvale’s long dry season from May through October lets roofing crews work without rain delays, but that same dry stretch masks flat-roof and waterproofing failures on older commercial buildings until the first November storm. The 1950s-70s ranch stock we see most often still carries original three-tab asphalt shingles past their 20-25 year design life, or low-slope torch-down assemblies that have cracked at the seams. We inspect every roof with a documented photo record, deliver a written scope and flat price before any tear-off begins, and back our work with the 365-Day Done Right Promise. Roofing is our most called-on trade in Sunnyvale because roof condition directly affects whether a home sale clears inspection or a refinance appraisal holds value.
Roof Repair
Signs you need it
Water stains on ceiling drywall, granules collecting in gutters, or lifted shingle tabs along the rake edges of your roof.
What it costs in Sunnyvale
Roof repair in Sunnyvale typically runs $400-$1,800 depending on whether we’re replacing a few damaged shingles, resealing vent penetrations, or patching a low-slope membrane section.
How we do it
We photograph the damage from the ridge and the deck, match existing shingle color and manufacturer where possible, and provide a written warranty on the repair scope.
Roof Replacement & Installation
Signs you need it
Multiple leak points, shingles curling or losing granules across more than 30% of the field, or an original roof past 25 years on a home you’re considering for sale.
What it costs in Sunnyvale
Roof replacement in Sunnyvale ranges $8,000-$20,000 for standard asphalt shingle assemblies on the typical 1,200-1,800 sq ft ranch footprint.
How we do it
We strip to deck, inspect and replace compromised sheathing, install synthetic underlayment and ice barrier at valleys and eaves, then finish with GAF or Owens Corning shingles per your written selection.
What Roofing Costs in Sunnyvale
| Item | Typical range 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 ranch homes take two to four working days, with permits pulled and inspections scheduled before crews arrive. Call (650) 560-7228 for a written timeline with your free estimate.
Will a new roof increase my home value in Sunnyvale?
Yes - in a market where land values exceed $1.5M, a failing roof is a transaction killer; buyers and appraisers flag it immediately, and a documented new roof with transferable warranty removes that friction. Call (650) 560-7228 to review how replacement timing affects your sale schedule.
Windows & Doors in Sunnyvale
The original single-pane aluminum windows in Sunnyvale’s 1952-1975 ranch stock conduct heat and cold at rates that make Title 24 compliance impossible without replacement, which is why window upgrades are almost always triggered by a permit pull rather than by homeowner choice alone. We install vinyl, fiberglass, and composite units from manufacturers that meet or exceed the NFRC ratings Sunnyvale’s plan checkers verify, and we document the rough opening condition with photos before any frame goes in. Windows & Doors projects here run from discrete replacements to whole-home packages timed with exterior re-siding.
Window Replacement
Signs you need it
Condensation between panes, frames that leak air around the weatherstrip, or single-pane aluminum units that fail Title 24 when any renovation permit is pulled.
What it costs in Sunnyvale
Window replacement in Sunnyvale ranges $4,500-$15,000 for a typical ranch home, depending on unit count, material, and whether James Hardie trim replacement is bundled.
How we do it
We measure each rough opening, check for water intrusion at the sill, install flashed and sealed replacement units with Low-E coating, then photograph the completed installation for your record.
Impact Windows & Doors
Signs you need it
Homes in wind-exposed western Sunnyvale near the Bay, or owners converting to rental ADUs who want tenant-damage resistance and reduced insurance exposure.
What it costs in Sunnyvale
Impact window installation in Sunnyvale runs $8,000-$25,000 for a full home package, with laminated glass and reinforced frames that exceed standard impact ratings.
How we do it
We engineer the attachment for your specific wall construction - whether stucco over wood frame or original board-and-batten - and provide the structural calculations Sunnyvale requires for permit approval.
What Windows & Doors Costs in Sunnyvale
| Item | Typical range in Sunnyvale |
|---|---|
| Window Replacement | $4,500-$15,000 |
| Impact Window Installation | $8,000-$25,000 |
| Energy-Efficient Windows | $4,500-$15,000 |
Do I have to replace all windows at once in Sunnyvale?
No - we can phase replacements by exposure or floor, though Title 24 compliance on a permitted remodel may require minimum efficiency thresholds for all windows in the conditioned space. Call (650) 560-7228 to review phasing options with a written quote per phase.
How do I know if my window frames are rotted?
Probe the sill with a screwdriver; soft wood, visible fungal growth, or paint that bubbles from moisture behind it indicates decay that requires frame replacement, not just sash insertion. Call (650) 560-7228 and we’ll document the condition with photos during your free estimate.
Fence Installation in Sunnyvale
Fence installation in Sunnyvale operates at the intersection of privacy needs, HOA design guidelines in newer developments, and the reality that many 1950s-70s lots never had perimeter fencing installed originally. We see two distinct project types: owners of original ranches adding first-time privacy barriers, and owners of rebuilt or heavily renovated homes replacing deteriorated wood fences with materials that match a higher-grade aesthetic. Fence Installation in Sunnyvale requires attention to property line surveys - many of these older parcels have unrecorded agreements or encroachments that a written quote should account for before posts go in.
Vinyl Fence
Signs you need it
HOA-mandated replacement of a failing wood fence, or a desire for zero-maintenance perimeter fencing on a rental property or ADU.
What it costs in Sunnyvale
Vinyl fence installation in Sunnyvale ranges $3,500-$9,000 for a typical 6-foot privacy perimeter on a 6,000-8,000 sq ft lot.
How we do it
We locate property pins or reference your survey, set posts in concrete below the frost line, and install tongue-and-groove vinyl panels with aluminum reinforcing rails.
Aluminum Fence
Signs you need it
Pool safety barrier requirements, ornamental front-yard fencing on a rebuilt home, or a need for visibility with boundary definition.
What it costs in Sunnyvale
Aluminum fence installation in Sunnyvale runs $4,000-$10,000 depending on height, picket style, and gate count.
How we do it
We powder-coat match to your specification, set posts with core-drilled anchors on existing hardscape or poured footings on grade, and provide pool-code-compliant self-closing hardware where required.
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 |
| Wood Fence Installation | $3,500-$9,000 |
Do I need a permit for a fence in Sunnyvale?
Fences under 6 feet typically do not require a building permit in Sunnyvale, but corner lots have visibility triangle restrictions and some HOAs impose design review; we verify both before quoting. Call (650) 560-7228 and we’ll confirm requirements for your specific parcel.
How long does a vinyl fence last in Sunnyvale’s climate?
Quality vinyl fencing lasts 20-30 years in Sunnyvale’s mild, non-freezing climate, with UV inhibitors preventing the brittleness that affects vinyl in desert or high-elevation installations. Call (650) 560-7228 for material specifications and a written quote.
Driveway & Pavers in Sunnyvale
Driveway and paver work in Sunnyvale faces the seasonal movement of Bay mud and alluvial fill in western neighborhoods, which cracks rigid concrete slabs and shifts paver beds if the base course is inadequately compacted. The long dry season allows extended curing and compaction windows, but also means homeowners forget about drainage until the first winter storm pools water against the foundation. Driveway & Pavers projects here range from replacing oil-stained original concrete on a ranch home to installing Belgard or Techo-Bloc paver systems on a rebuilt property where the driveway is now the largest visible hardscape element.
Paver Driveways
Signs you need it
Spiderweb cracking across original concrete, pooling water that stains the garage floor, or a desire for permeable surfacing that reduces runoff volume on a tight lot.
What it costs in Sunnyvale
Paver driveway installation in Sunnyvale ranges $7,000-$18,000 depending on paver species, pattern complexity, and whether we regrade for drainage.
How we do it
We excavate to 8-10 inches, install geotextile and compacted Class II base in lifts, set edge restraints on concrete haunching, and lay pavers with polymeric sand joint stabilization.
Concrete Driveways & Concrete Work
Signs you need it
Original 1950s-60s concrete with exposed aggregate, surface spalling from freeze-thaw cycling in unusually cold winters, or settlement cracks that channel water toward the foundation.
What it costs in Sunnyvale
Concrete driveway installation in Sunnyvale runs $4,500-$12,000 for a standard two-car width, with reinforcement and control joint spacing engineered for the soil conditions.
How we do it
We form to pitch away from the structure, place #3 rebar on 18-inch centers, pour 3000 PSI concrete with air entrainment, and saw-cut control joints within 24 hours.
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 pavers be installed over my existing concrete driveway in Sunnyvale?
Sometimes - if the existing slab is structurally sound, properly pitched, and not severely cracked, we can overlay with a thin paver system; otherwise removal and proper base preparation is the only durable solution. Call (650) 560-7228 for a structural assessment and written options.
How long before I can drive on a new paver driveway?
Polymeric sand requires 24 hours to set, and we recommend 48 hours before vehicle traffic; the base compaction is immediate, but joint stabilization needs the cure time. Call (650) 560-7228 to schedule work around your access needs.

FAQs About Construction in Sunnyvale
Sunnyvale’s building department is one of the highest-volume offices in Santa Clara County, so plan check times run longer than neighboring cities; we mitigate this with pre-application meetings and expediting relationships built over years of repeat submittals.
