Frequently Asked Questions

Most Cupertino home additions take 4 to 7 months from permit approval to final inspection, with framing and weatherproofing consuming the bulk of that time. The City of Cupertino's plan check process typically adds 6-10 weeks before construction can start. We build that timeline into our project schedule and text you updates at each phase. You'll know who's arriving and when.

We walk the space, take photos and measurements, ask how you use the area, and identify structural constraints. Within 48 hours, you receive a written scope with a fixed price. No verbal ballpark that shifts later. Grant Rowan or a senior estimator handles the visit personally for projects over $25,000.

Yes. We pull all required permits through the City of Cupertino Community Development Department and schedule inspections at rough-in, framing, and final. Our permit package includes structural calculations when needed, and we don't start demolition until permits are in hand. You receive copies of all approved plans and inspection sign-offs for your records.

Often yes, depending on the scope. We seal work areas with dust barriers and maintain temporary kitchen or bathroom access where possible. For whole-house renovations in Cupertino's older Ranch-style homes near Rancho Rinconada, we may recommend temporary relocation during the demolition and rough-in phases. We discuss this during your estimate so you can plan.

We lay Masonite pathways over flooring, tarp landscaping near work zones, and haul debris daily rather than letting it accumulate. Our crews use designated entry points and lock up at day's end. Photos document the condition of adjacent spaces before we start. Evidence on every job is Haven Standard Clause 4.

We install CWS, ES Windows, and ECO Window Systems for most Cupertino projects, with Mr-Glass specified where impact resistance or acoustic dampening is required. Each brand offers different performance tiers for Title 24 compliance, which matters given Cupertino's strict energy code enforcement. We specify the exact brand, model, and U-factor in your written quote so you're comparing identical products if you get other bids.

Yes. Our supply relationships give us access to commercial-grade fasteners, engineered lumber, and waterproofing membranes that aren't stocked at retail. For example, the ZIP System sheathing we use on Cupertino additions provides integrated water-resistive barrier and air sealing in one step, versus house wrap applied in the field. We itemize materials in your scope so you know what you're paying for.

You can, with conditions. Customer-supplied items must arrive on site before the relevant phase begins, and we warranty our installation work only, not the product itself. We've seen delays in Cupertino projects when homeowners ordered custom fixtures with 12-week lead times. We help you coordinate delivery dates with our construction schedule to avoid holding up the crew.

Yes. Every pro working under our name is required to hold the California contractor license and insurance the state requires. We carry general liability and workers' compensation coverage, and our license numbers appear on every written quote. You can verify status through the California Contractors State License Board. Grant Rowan oversees compliance for all Cupertino-area projects.

Require general liability, workers' compensation, and a current California contractor license. Ask for certificates of insurance naming you as additional insured during the project period. Unlicensed operators are common in Silicon Valley's high-cost market, and hiring one voids your homeowner's policy protection if someone gets hurt or damage occurs. We provide these documents before you sign.

The tradespeople on your Cupertino project are independent specialists who meet Haven Standard Clause 3 requirements: licensed in their trade, insured, and background-checked. We verify credentials before they step on your property, and their license numbers are available on request. Grant Rowan selects and manages the crew for each project based on the specific skills required.

True emergencies involve structural compromise that threatens safety or allows weather intrusion: a tree-struck roof section, a failed retaining wall, or a deck collapse. Our phone is answered 24/7, and we assess whether temporary stabilization or full repair is needed. Planned repairs, including rot replacement or settling crack repair, are scheduled during normal business hours with a written quote in advance.

Yes. We provide temporary weatherproofing and structural bracing for storm-damaged homes in Cupertino, Saratoga, and Los Gatos. Our first step is securing the opening or compromised structure to prevent further damage. We then photograph everything for your insurance claim and provide a written repair scope once conditions are stable. Call (669) 202-9618 any time.

We answer calls 24/7 and dispatch for assessment as soon as road conditions and crew availability allow. Cupertino's winter storm patterns, particularly in the Foothill areas above 500 feet elevation, can cause sudden roof or siding failures. Our emergency response focuses on stopping the water first, then documenting the damage, then planning permanent repair with a fixed-price quote.

Every project carries a written workmanship warranty documented in your contract before work begins. Structural work is warranted for 10 years; finish carpentry and tile for 2 years. We don't bury warranty terms in fine print. Haven Standard Clause 1 requires the warranty in writing, and Clause 4 requires photo documentation of completed work so any future claim references actual conditions.

You call (669) 202-9618 and we come look. If it's our work, we fix it. If it's material failure under manufacturer warranty, we coordinate with the supplier and handle the replacement labor. We've worked with CWS, ES Windows, and ECO Window Systems long enough to know their claim processes. The documented record from your project, including photos and product serial numbers, speeds resolution.

We warranty our work only. If your Cupertino home has unpermitted prior construction that we discover during demolition, we stop and document it. We can bring that work into compliance with the City of Cupertino, but it's a separate scope with its own quote. We don't warranty structural elements we didn't build or inspect.

Workmanship warranties are tied to the original contract and generally don't transfer to subsequent owners. However, the permits we pull and the documentation we provide become part of your home's record and add value at sale. Buyers in Cupertino's competitive market specifically ask for permit history on additions and major remodels. We provide complete permit and inspection documentation for your disclosure packet.
