Why Sunnyvale Homeowners Choose Rowan Construction Group Sunnyvale for Construction
Since 2007, Rowan Construction Group has delivered over 4,000 projects with a written price before work started and a documented record when we left. Our Sunnyvale branch, led by Grant Rowan, brings that same standard to homeowners across Santa Clara County. We don’t think you should have to guess what your project will cost or wonder what actually happened behind your walls.
6 Reasons We’re Sunnyvale’s Top Construction Company
1. Nearly Two Decades of Local Market Knowledge
We’ve been working in this region since 2007, which means we’ve built through the full cycle of Silicon Valley housing. We’ve worked on Eichlers in Sunnyvale’s Birdland neighborhood, handled seismic retrofits for soft-story townhomes near downtown, and managed additions where Cupertino’s strict tree preservation codes complicated the foundation work. That history matters when your project hits a condition the plans didn’t anticipate. We know which Sunnyvale inspectors will flag a shear-wall detail and how Mountain View’s ADU setbacks differ from Santa Clara’s.
2. Strong Local Reputation You Can Verify
We don’t ask you to trust us blindly. Our customers in Sunnyvale, Los Altos, and Cupertino have left detailed feedback you can read, including the three-star reviews where something went wrong and we fixed it. We respond to every review because Clause 4 of the Haven Standard, Evidence on every job, applies to our reputation too. If you want to talk to a recent customer near you, we’ll connect you with a homeowner in your area who had similar work done.
3. Every Pro Is Required to Carry Proper License and Insurance
Under the Haven Standard, every contractor working under our name is required to hold the license and insurance California requires for their trade. We don’t send anyone to your home who isn’t properly credentialed. You’ll see the license number on your written quote, and we’ll pull permits through the City of Sunnyvale or whichever jurisdiction covers your property. For work in Palo Alto’s historic districts or Saratoga’s hillside zones, we handle the additional planning reviews those locations require.
4. Certified Expertise with Premium Brands
We specify products we know perform well in this climate. For roofing in Sunnyvale’s sun-exposed hills, we often recommend CertainTeed’s reflective shingle lines or Owens Corning’s duration series, both rated for the thermal cycling that cracks lesser materials. In kitchens, we design with KraftMaid and Wellborn cabinetry and quote Cambria quartz surfaces with the full fabrication and install scope included. We don’t markup materials mysteriously; you see the line item.
5. Fixed Pricing in Writing Before We Start
Our founding lesson from 2007 was simple: optimism doesn’t pay for change orders. That’s why no work proceeds on a change until the change order is signed. Your initial quote is a flat price with a written scope. If we find rot behind your siding or asbestos in your floor tile, we document it with photos, explain the finding in plain terms, and you sign the change order before we proceed. Our projects finish within a few percent of the number you agreed to, not double it.
6. The Haven Standard Guarantee
Every job leaves a documented record: photos, readings, and a signed completion checklist. If something isn’t right, we come back. The warranty terms are written on your contract, not implied. For Sunnyvale homeowners, that means if your new roof leaks or your addition settles unevenly, you have a local team to call and a national standard backing the response. Grant Rowan personally reviews any callback that isn’t resolved in one visit.
Our Promise to You

We operate under five values we call H.A.V.E.N. Have it in writing means your flat price, scope, and warranty are documented before anyone starts. Arrive on schedule means a real window, a named lead, and a text when we’re on the way. Verified crews means licensed, insured, background-checked professionals. Evidence on every job means photos and readings of what we actually found. No surprises means no door upsell, no scope creep, no “while we’re in here.”
If you’re not satisfied with any aspect of our work, call us at (650) 405-3637 during our business hours: Monday through Friday 7:30 AM to 8:00 PM, Saturday and Sunday 8:30 AM to 7:00 PM. A live coordinator will connect you with our local team. We’ll return to assess the issue, document what we find, and correct it under the terms of your written warranty. We don’t disappear after final payment. Our pricing transparency commitment is absolute: the quote you sign is the price you pay, unless you approve a documented change in writing.

AfterFrequently Asked Questions
Most contractors in Sunnyvale can build; few will give you a fixed written price before starting and stick to it. Since 2007, we’ve completed over 4,000 projects under The Haven Standard, which requires written scope, documented evidence, and no surprise charges. We’re locally operated by Grant Rowan, not dispatched from a remote office. Call (650) 405-3637 to schedule your free written estimate and compare our quote line-by-line.
We return and fix it under your written warranty terms. If the issue isn’t resolved in one visit, Grant Rowan personally reviews the case to determine the right remedy, whether that’s additional repair, partial credit, or another solution documented in writing. We don’t consider a job complete until you sign the satisfaction checklist. Call (650) 405-3637 if anything concerns you, during our regular hours, and a live coordinator will connect you with our team.
No. Your written estimate is free and includes a detailed scope with line-item pricing. We don’t pressure you to decide on the spot or offer “today only” discounts. For complex projects in hillside areas like Saratoga or Los Altos, we may need two visits to assess access and drainage conditions before finalizing numbers. Call (650) 405-3637 to schedule yours.
Every professional working under our name is required to hold the California license and insurance their trade requires. We verify this before anyone represents Rowan Construction Group. Your written quote includes the responsible license number, and we pull all required permits through the City of Sunnyvale or your local jurisdiction. For work in Fremont, Newark, or Milpitas, we handle the specific permit processes those cities require.
We schedule estimates during our regular business hours: Monday through Friday 7:30 AM to 8:00 PM, Saturday and Sunday 8:30 AM to 7:00 PM. For most projects in Sunnyvale, Mountain View, Santa Clara, and Cupertino, we can typically book an estimate visit within a few business days. During peak spring and fall seasons, wait times may extend slightly. We don’t promise same-day arrival for planned construction work because proper estimating takes time, but we do commit to showing up in the window we give you with a text when we’re en route. Call (650) 405-3637 to check current availability.
