What Our Promise Actually Means
If something isn’t right with work Sutton ADU Builders completed for you, you tell us, we come back out, we fix it, and you don’t pay a cent for that visit – that’s the whole thing, and it’s in writing on every project we sign.
The 365-Day Done Right Promise isn’t a warranty card you have to register or a hotline that routes you to voicemail. It’s a named, written guarantee that travels with every project from the day we break ground to one full year after we hand you the keys. If workmanship fails inside that window, the fix is on us. No negotiating, no adjuster, no service fee. You call the same number you called to hire us, a real person picks up, and we get moving.
What you’re entitled to is simple: the work done right, and if it isn’t, a return visit to make it right – at no additional cost, no forms to mail in, and no haggling required. That’s not a generous policy. That’s the baseline we hold ourselves to.
Why We Answer Fast, Everywhere

A homeowner spending five or six figures on an ADU or addition deserves to reach a human being when something comes up – at 9 PM on a Friday, or early on a Sunday morning when they notice something looks off. A one-truck shop often can’t staff that. We can, because Sutton ADU Builders is part of the Threshold Group family, and the infrastructure behind the brand is built to handle it.
Every call to (472) 248-8213 reaches a live person around the clock. When you need an estimate, we get an estimator to your property within two business days of that call, and the written estimate is in your hands within one business day of that visit. That window is real. We keep it honest through local, independently operating crews who know their markets, and through Threshold Verified dispatch standards that mean the right person is routed to your address – not whoever happened to pick up. National reach, local crew, actual accountability. That’s the combination a single-crew operation genuinely can’t match.
How We Make It Right
You Tell Us
Call (472) 248-8213 and describe what you’re seeing. You don’t need photos, a written description, or any specific language – just tell us what doesn’t look or feel right. The person who answers is there to listen and log it, not to screen you out. We open a return visit from that first call.
We Come Back Out
An estimator or crew member from your original project returns to assess what happened. There’s no fee for this visit – it’s part of the 365-Day Done Right Promise, and it’s built into how every Sutton project is structured. You’ll know who’s coming before they arrive, because that’s how we work on every visit, not just the first one.
We Fix It
If the issue falls within our workmanship, we repair it. The work is done to the same standard as the original build – same Threshold Verified crew standards, same upfront confirmation of what’s being done. We don’t patch and leave; we make sure the fix holds.
You Sign Off
We don’t close the return visit until you’re satisfied. That’s not a figure of speech. You confirm the work is right before we consider it done. If it still isn’t right, the promise still applies – it doesn’t expire the moment we pack up the truck.
What Stands Behind the Promise

Promises are only as good as the people and systems keeping them. Here’s what’s actually in place.
Every technician who works on a Sutton project is background-checked and identity-verified before they ever set foot on a property. Before they arrive at yours, you receive their name and photo. At the door, they show a photo ID badge and arrive in a clean, marked uniform. If anyone shows up who you weren’t notified to expect, that visit is on us and we make it right – no debate, no exception. That standard is called Threshold Verified, and it applies to every Sutton crew member on every visit.
Pricing works the same way. Every project gets a written price before any work begins – no hourly rates, no subscriptions, nothing to sign up for. Your estimate is free, it’s specific, and it doesn’t change once work starts. The number you approve is the number you pay. That’s the only pricing mechanism we operate.
On the materials side, Sutton works with recognized ADU product lines including Abodu, Cover, Dvele, Mighty Buildings, Boxabl, and Plant Prefab, as well as James Hardie exterior cladding systems. You’re not getting whatever happened to be in stock. You’re getting honest guidance on which product fits your lot and your budget, from a team that knows those products well.
