The Sutton ADU Fort Worth Guarantee
When we build you an ADU or room addition in Fort Worth, you get something few contractors put in writing: a named, enforceable commitment to stand behind the work. The 365-Day Done Right Promise covers defects in workmanship for one full calendar year from project completion. If it isn’t right, Sutton makes it right, no haggling and no fee. Before any work starts, you receive a written price that doesn’t change unless you change the scope. Every technician who steps onto your lot is background-checked, identity-verified, uniformed, and photo-badged, with their name and photo sent to you before arrival. That’s the Threshold Standard, and it’s stamped on every project we build.
What’s Covered
- Workmanship for a full year. The 365-Day Done Right Promise covers defects in workmanship for one full calendar year from project completion, and if something fails during that window, we return and fix it.
- Written pricing before any work starts. You receive a line-item written price before we break ground, so there’s no surprise invoice and no scope creep passed silently to the bill.
- Free second visit if something fails. If a repair or element of the build doesn’t hold up, the follow-up visit is free, no negotiation and no diagnostic fee.
- Parts and materials handled correctly. When a component fails during the warranty period, we manage the replacement process with the manufacturer and handle the labor to make it right.
- On-time arrival with verified crew. The person showing up is the person whose name and photo we sent you, wearing a marked uniform and carrying a photo ID badge, every time.
- Clean job site at the end of each day. We treat your Fort Worth lot like it’s still your home, because it is; we’re building a second home on it, not leaving a construction zone behind us.
- Straight answers on what your lot can handle. We work with Abodu, Cover, Dvele, Mighty Buildings, Boxabl, and Plant Prefab, plus Tuff Shed conversions and James Hardie cladding, and we’ll tell you honestly which product line fits your budget and your property, not which one earns us the best margin.
Our Satisfaction Promise
The guarantee has teeth because we built it into how we operate, not just how we advertise. Here’s how the make-it-right process works in Fort Worth. You call us at (682) 255-2399 and tell us what’s wrong. We schedule a return visit at a time that works for you. A Sutton technician comes out, diagnoses the issue, and if it falls under the 365-Day Done Right Promise, we do the work to correct it at no charge. If the fix requires a manufacturer part, we coordinate that, we handle the labor, and we keep you updated on timing. If you’re not satisfied with an element of the build, we don’t argue about whether it’s covered. We schedule a visit, look at it together, and work through the options. Miles Hartwell has run enough Fort Worth builds to know that a homeowner who gets straight talk during the warranty process is a homeowner who refers their neighbors. The promise isn’t a marketing line. It’s the operating rule.
Licensed & Insured Backing

A written guarantee is only as strong as the company behind it. Sutton ADU Fort Worth is licensed and insured, which means every project has a real financial and legal foundation underneath it, not just a handshake. The Threshold Group family of home-service companies operates under Threshold Verified standards, and our Fort Worth location follows the same system: background-checked crews, written pricing, and a named warranty. When you hire us, you’re not hiring a pickup truck and a ladder. You’re hiring a business with the insurance and licensing in place to stand behind the work for a full year after the final walkthrough. That’s the actual guarantee behind the paperwork.
