Frequently Asked Questions - Construction in Sunnyvale, CA
We've been building and remodeling in Sunnyvale since 2007. Here are the questions we hear most, answered with the specifics you're actually looking for.
Pricing & Cost FAQs
A typical home addition in Sunnyvale runs between $350 and $550 per square foot, depending on foundation work, structural tie-ins, and finish level. Second-story additions over existing single-story homes in neighborhoods like Cherry Chase or Birdland often land at the higher end because of structural reinforcement and the need to match existing rooflines. We provide a written, line-item quote before any work begins under Haven Standard Clause 1. Call (650) 405-3637 to schedule your free estimate.
Kitchen remodels in Sunnyvale typically range from $45,000 for a mid-range refresh to $120,000 for a full gut with structural changes and premium finishes. The biggest variables are cabinet quality, whether you're moving plumbing or gas lines, and how the space connects to adjacent rooms. Homes built in the 1960s and 1970s around Sunnyvale often need electrical panel upgrades to handle modern appliance loads, which adds $3,000-$8,000. We itemize everything in writing so you know where your money goes.
No. Our price is fixed once you sign the written scope. Haven Standard Clause 3 requires that any change order is agreed in writing before the additional work proceeds, not after. In 19 years of operation since 2007, this practice is why our projects finish within a few percentage points of the original quote. The only price movement comes from changes you request and approve in advance.
Yes. Every estimate is free, written, and itemized. We'll walk your property, take photos and measurements, and return a scope document with a fixed price. No deposit is required to receive your quote. Call (650) 405-3637 to schedule yours.
Sunnyvale's Community Development Department requires permits for structural work, electrical, plumbing, and most exterior changes. Permit fees typically add $2,000-$6,000 to residential projects depending on valuation, and the inspection schedule adds 2-4 weeks to most timelines. We pull all required permits and coordinate inspections as part of our standard process, with those costs built into your written quote.
Service & Process FAQs
A typical bathroom remodel takes 3-5 weeks from demolition to final inspection, assuming standard fixture locations and no structural changes. Moving walls, relocating plumbing stacks, or custom tile work can extend this to 6-8 weeks. Sunnyvale's inspection availability is generally good, but we build buffer time into every schedule because inspection delays are the most common timeline variable we do not control.
We arrive in a marked window, introduce ourselves by name, and walk the project with you. We take photos, measurements, and notes on existing conditions. Within 48 hours, you receive a written scope with a fixed price, a proposed timeline, and the documentation you'll receive at project completion. No pressure to decide on the spot. Haven Standard Clause 2 requires we give you a real arrival window and text when we're on the way.
Yes. We pull all required permits and schedule all inspections with Sunnyvale's Community Development Department. You receive copies of every permit, inspection sign-off, and the photo documentation we collect at each phase. This is part of Haven Standard Clause 4: evidence on every job. You should never be left wondering whether your project passed inspection.
Often yes, depending on the scope. Kitchen-only remodels usually allow you to stay, though you'll need a temporary cooking setup. Full-gut renovations or projects that affect multiple bathrooms typically require relocating for at least part of the timeline. We'll tell you honestly during estimation what the livability situation will be, and we sequence work to minimize disruption when you stay.
We work regularly in Mountain View, Santa Clara, Los Altos, Cupertino, Palo Alto, Saratoga, Milpitas, Newark, Campbell, Fremont, and Menlo Park. Our crews know the local building departments, soil conditions, and architectural styles across Santa Clara County and southern San Mateo County. A project in Los Altos Hills faces different drainage and setback requirements than one in central Sunnyvale, and we account for those differences in planning.
Brands & Parts FAQs
For Sunnyvale's Mediterranean climate with dry summers and mild, wet winters, we typically specify CertainTeed Landmark shingles or Owens Corning Duration series. Both handle the thermal cycling from hot days to cool nights without premature cracking, and both carry strong wind warranties for the occasional Santa Clara Valley storm. We also install IKO Cambridge architectural shingles when homeowners want a specific color profile, and Atlas StormMaster Slate for premium projects requiring Class 4 impact resistance.
Yes. Your written scope specifies the product lines and grades we've priced, and you can upgrade or substitute within reason. We source through national buying programs that keep our prices honest, and we pass that leverage to you. If you have a specific material in mind, tell us during estimation and we'll price it accurately rather than guessing.
We order long-lead items at contract signing, not at demolition. Windows, custom cabinets, and certain roofing materials can run 6-10 weeks in the current market. Our project timelines build in realistic procurement schedules so we're not standing idle waiting for delivery. You'll see material delivery dates in your project schedule before work starts.
Licensing & Insurance FAQs
Yes. Every professional working under our name in Sunnyvale is required to hold the California contractor license and insurance the state requires. We verify these credentials before anyone steps onto your property. Your written quote includes the license number of the responsible contractor, and we carry general liability and workers compensation coverage as required by law.
We maintain general liability and workers compensation insurance as required for California contractors. We can provide certificates of insurance on request. This protects you from liability if someone is injured on your property or if accidental damage occurs during construction. We do not treat this as optional or ask you to accept risk we should carry.
The crews working under our name in Sunnyvale are independently contracted specialists who meet our verification requirements. Haven Standard Clause 3 requires that every tradesperson on your job is licensed, insured, and background-checked to the standards their trade requires. We do not send unverified labor to your home.
Emergency & Response FAQs
We address urgent structural issues, storm damage, and safety hazards during our operating hours: Monday through Friday 7:30 AM to 8:00 PM, Saturday and Sunday 8:30 AM to 7:00 PM. For true emergencies like roof failures or structural compromises, call (650) 405-3637 and our live coordinator will connect you with the local team. We do not promise after-hours response for non-emergency situations, and we do not claim 24/7 availability.
Stop work in the affected area and call us immediately at (650) 405-3637. We will assess whether the damage is within our scope or requires a remediation specialist. If mold is present, California law requires licensed remediation before we can proceed with reconstruction. We document everything with photos and coordinate with your insurance if the damage is from an external cause. Never ignore water damage, it compromises structural integrity and creates health hazards.
Start dates depend on scope, permit timeline, and current backlog. Smaller projects often begin within 2-4 weeks of contract signing. Larger additions or whole-home renovations may schedule 6-10 weeks out to allow for permit approval and material procurement. We give you a realistic start date during estimation, not an optimistic one to win your signature.
Warranty & Guarantees FAQs
Every project carries a written workmanship warranty, specified in your contract before work begins. Specific terms vary by project type and are detailed in your scope document. Haven Standard Clause 1 requires that warranty terms are in writing before anyone starts, not promised verbally after the fact. We also pass through all manufacturer warranties on materials like roofing, windows, and fixtures.
Call us at (650) 405-3637. We document every project with photos and records of what we found and what we did. If the issue relates to our work, we address it under the terms of your written warranty. If it's a manufacturer defect or unrelated maintenance issue, we'll tell you honestly and help you navigate the right solution. Haven Standard Clause 5 is no surprises, and that applies after project close too.
We provide a written schedule with your contract and update you weekly on progress. Delays from weather, inspection availability, or owner-requested changes are noted in writing with revised completion estimates. We do not promise timelines we cannot control, and we do not absorb the cost of delays caused by factors outside our scope. What we guarantee is transparency about where your project stands at all times.
You receive a project closeout packet including: final photos of completed work, copies of all permits and inspection sign-offs, manufacturer warranty documents, your workmanship warranty terms, and an itemized final accounting showing no deviation from your approved scope. Haven Standard Clause 4 requires evidence on every job, and that evidence belongs to you when we leave.
