Contact Rowan Construction Group Sunnyvale - Free Construction Estimate in Sunnyvale
Call (650) 405-3637 to schedule your free construction estimate in Sunnyvale. When you reach us, you’ll speak with a live coordinator who connects you directly with our local team - no hard sell, no pressure, just a convenient time for us to assess your project and deliver a written quote. Most Sunnyvale homeowners receive their assessment appointment within two to three business days of calling.
What Happens When You Call
Step 1: We answer and listen. A live coordinator picks up during business hours, takes your details, and connects you with our local Sunnyvale team. We’ll ask about your project scope, your timeline, and any concerns you’ve run into with other contractors.
Step 2: We schedule your on-site assessment. We agree to a real arrival window, not a vague “morning or afternoon” block. You’ll get a text when our estimator is en route. The assessment typically takes 30 to 60 minutes depending on project complexity.
Step 3: You receive a written, line-item estimate. Within 24 to 48 hours of the assessment, we deliver a fixed-price quote with every material and labor line spelled out. This is Clause 1 of the Haven Standard: the price is agreed in writing before any work begins. No verbal ballparks, no hidden categories.
Step 4: Work proceeds on scope, on schedule. Once you approve the estimate, we pull permits if required, order materials from suppliers like CertainTeed or Owens Corning, and execute the written scope. Change orders, if needed, are signed before the additional work starts - the reason our projects finish within a few percent of the original number.
Why Sunnyvale Homeowners Call Us First

- Local response times that respect your schedule. We’re based in Sunnyvale, not dispatched from San Jose or the East Bay. That means our estimators reach homes in the Birdland, Cherry Chase, and Lakewood neighborhoods without the traffic delays that push other contractors past their windows.
- Required licensing and insurance, verified and on record. Every pro working under our name is required to hold the license and insurance California requires for their trade. We keep license numbers on file and available upon request - no hand-waving, no “trust us.”
- Transparent pricing with no hidden fees. Your written estimate lists every material line, every labor hour, every permit cost. We use our buying power with brands like IKO and Atlas to keep material costs honest, and we pass that through rather than marking it up mysteriously.
- Workmanship backed by the Haven Standard. Every job leaves a documented record: photos of what we found, readings we took, and what we did. The written warranty is part of your project file, not a verbal promise that evaporates after the final invoice.
Before
AfterOur Service Area Around Sunnyvale
We serve Sunnyvale directly, with assessment appointments typically available within two to three days in Mountain View, Santa Clara, and Cupertino. For Los Altos, Palo Alto, Saratoga, and Campbell, expect three to four business days. Milpitas, Newark, Fremont, and Menlo Park fall within our extended service radius, usually scheduled within four to five days. If you’re outside these cities - Los Gatos, Redwood City, the Almaden Valley - call anyway. Our coordinator will tell you honestly whether your project fits our route efficiency, and we’ve taken jobs in unlisted areas when the scope justifies the travel.
Frequently Asked Questions - Booking & Estimates

Yes. The on-site assessment and written estimate are completely free, with no obligation to hire us. We believe you can’t make an informed decision without a real number in hand, so we deliver one before asking for any commitment. Call (650) 405-3637 to schedule yours.
We typically schedule assessments within two to three business days for Sunnyvale addresses. During peak spring and fall seasons, that may stretch to four days. We’ll give you an honest timeframe when you call, not an optimistic one we’ll miss. Call (650) 405-3637 for our current availability.
No. Our Saturday and Sunday hours - 8:30 AM to 7:00 PM - are standard operating time, not premium slots. Evening assessments on weekdays are available until 8:00 PM Monday through Friday at the same rate as morning appointments. The estimate itself is always free regardless of when we meet. Call (650) 405-3637 to find a time that works.
Your address, a brief description of the project, and any relevant timeline constraints. If you have prior contractor quotes, inspection reports, or HOA requirements, have those handy for the assessment visit - they help us scope accurately and avoid surprises. The coordinator will confirm what to gather when you call (650) 405-3637.
We accept check, ACH transfer, and all major credit cards. For larger projects, we offer a payment schedule tied to documented milestones - typically a deposit at contract signing, a progress payment at rough inspection, and final payment upon completion and your sign-off. We never demand full payment upfront. Call (650) 405-3637 to discuss payment structure for your specific project.
