The Sutton ADU Sacramento Guarantee
We put our name on every ADU, room addition, and home addition we build in Sacramento. That means something specific: before any work starts, you get a written price. For a full calendar year after we finish, the 365-Day Done Right Promise covers defects in workmanship. If anything isn’t right, we come back and make it right. No haggling. No invoice for the second visit. Miles Hartwell founded this company on the idea that a guarantee should be a written contract, not a handshake. That’s the whole point of the Threshold Standard we operate under.
What’s Covered
- Workmanship for 365 days. The 365-Day Done Right Promise covers defects in workmanship for one full calendar year from project completion, in writing, on every project.
- Written price before work begins. You receive a line-item price in writing before we ever break ground, so the number you approve is the number you pay.
- Free second visit if something fails. If a repair or element of the build fails within the guarantee period, we schedule a return visit at no cost to you.
- Clean job site at the end of every day. Our crews keep the work area tidy while the project is active and do a final sweep before we walk you through the finished space.
- Verified people on your property. Every technician is background-checked, identity-verified, uniformed, and photo-badged, and you get their name and photo before they arrive.
- Straight answers on materials and products. We work with recognized ADU systems like Abodu, Cover, Dvele, Mighty Buildings, Boxabl, and Plant Prefab, plus James Hardie cladding, so you know exactly what’s going into your build.
Our Satisfaction Promise
Here’s how it works if something isn’t right. Call the office at (279) 300-1690. A live person answers, any hour of any day. You describe the problem. We pull your file, look at the original written price and the scope we agreed to, and we schedule a second visit at no charge. There’s no phone tree, no claims department, and no one asking you to prove the issue eleven different ways. Miles Hartwell’s instruction to every project lead is simple: if our work fell short, we fix it. The 365-Day Done Right Promise is exactly that. Not a prorated warranty that shrinks by the month. Not a “reasonable wear and tear” escape clause. One full year, and if the workmanship doesn’t hold up, Sutton ADU Sacramento makes it right. Homeowners around Sacramento will tell you the most valuable line on any contract is the one that says what happens when things go wrong. Ours says we come back, on our dime, and we don’t leave until it’s correct.
Licensed & Insured Backing
A guarantee is only worth the company standing behind it. We’re licensed and insured, which means the paperwork holds real weight. If something goes wrong on a job site, our insurance coverage protects your property and the people working on it. Licensing means we answer to the State of California’s contractor requirements, not just our own standards. Those aren’t optional extras. They’re the foundation under every room addition and detached ADU we build in Sacramento. When you compare bids, ask each contractor to show proof of both. We’ll show ours without being asked. The written price, the 365-Day Done Right Promise, and the crew vetting are all part of the Threshold Verified system that governs every Sutton location, including ours here in Sacramento.
How to Make a Claim
If you’re within one calendar year of project completion and you believe our workmanship fell short, call (279) 300-1690. Tell whoever answers what you’re seeing. We’ll review your project notes, confirm the scope against your original written price, and schedule your free second visit. You don’t need a claim number. You don’t need to mail anything. You need to make one phone call. That’s the extent of the process. It’s designed to be that simple because we’d rather spend our time fixing the problem than administering the complaint.
Why Sacramento Homeowners Ask About Guarantees First
ADU construction in Sacramento is a significant investment, often the largest single project a homeowner takes on short of building a house from scratch. Permitting through the City of Sacramento and Sacramento County takes time, site conditions vary block by block, and a foundation pour in Oak Park or Land Park brings different challenges than one in Natomas or East Sacramento. Given all that, the guarantee question isn’t really about paranoia. It’s about knowing the contractor expects to be held accountable. We do. The 365-Day Done Right Promise exists because Miles Hartwell saw too many Sacramento homeowners accept verbal reassurances that evaporated the first time something cracked. A south farm, which is what Sutton means in old English, is a place where things are meant to last. That’s how we build.
What the Guarantee Does Not Cover
Honesty about limits matters as much as the promise itself. The 365-Day Done Right Promise covers defects in our workmanship. It does not cover damage caused by homeowner modification, neglect, natural disasters, or issues unrelated to the work we performed. Manufacturer warranties on products like prefab ADU modules, James Hardie siding, windows, doors, and appliances are handled through the manufacturer’s own warranty terms, and we’ll help you navigate those if a product fails. We don’t extend those warranties or pretend they’re longer than they are. What we control is how we build, and that’s what we guarantee. Clear scope written before work starts, clear limits written into the guarantee. That’s the Sutton way, and it’s the only way guarantees actually mean something.
