The Fielding ADU West Covina Guarantee
We put our guarantee on paper before we pick up a hammer. That’s the difference between a contractor who hopes the job holds up and one who’s willing to bet on it. Every addition, garage conversion, and ADU we build in West Covina carries The Garrison Standard: a written one-year workmanship guarantee. If something fails within 365 days of completion, we come back and fix it at no charge. No phone tag, no arguing about whose fault it is, no invoice on your doorstep. Reed Calloway, Owner of Fielding ADU West Covina, signs off on every project personally, and the guarantee travels with the work.
What’s Covered
- Workmanship defects, in writing. If framing, drywall, finish work, or any installed component fails because of how it was built, we correct it under The Garrison Standard, which runs for one full year from the day the project is completed.
- Materials and parts handling. When a product fails, we manage the manufacturer claim and reinstall the replacement so you’re not stuck navigating warranties alone.
- The price you approved. Your written price is handed to you before any work starts. The number on the final invoice matches the number on day one, every time, with no exceptions.
- Clean worksite, daily. We leave the site clean at the end of each workday. That’s part of The Garrison Code: leave it clean, stand behind it for a year.
- On-time arrival, honestly communicated. If the schedule shifts, you hear it from us, not from a silent day with no crew at your house.
- A crew you can identify. Every person on your property is background-checked and arrives in uniform, so you always know who belongs on the job site.
Our Satisfaction Promise
If something isn’t right, you call us and a live person picks up. That’s not a slogan; it’s how the phone works at Fielding ADU West Covina. Someone answers at noon, at midnight, on weekends. Reed Calloway hears about the issue directly, and the fix gets scheduled. Our 365-Day Done Right Promise is the mechanism: once a defect is reported within the guarantee window, we return at no charge and correct it. There’s no deductible, no trip fee, and no “that’s within industry tolerance” conversation. If it’s not done right, we make it right. That’s the entire promise, and it’s written on the paperwork you keep after the final walkthrough.
We also do something most West Covina contractors won’t: we offer a free second visit if the work fails inside that year. The guarantee spells out what it covers, how long it runs, and exactly how we make it right. You’ll know before you sign what happens if a door settles, a seam opens, or a finish fails. No fine print surprises.
Licensed & Insured Backing
A paper guarantee is only as good as the company standing behind it. Fielding ADU West Covina operates licensed and insured, which means the work is permitted, the business is accountable, and you’re protected if something goes sideways. Insurance covers your property while our crew is on it. Licensing means the city of West Covina has reviewed our credentials and we’re subject to California’s contractor laws, including the rules on deposits, change orders, and lien rights. That regulatory backing is the real enforcement behind our written guarantee. If we don’t perform, you have recourse that goes beyond our word. We’ve operated this way since 2006 through Garrison Partners, and the standard hasn’t moved.
What The Garrison Code Means in Practice
Our operating rules are simple enough to print on the back of an estimate: show up in the window, price in writing, by the book, leave it clean, stand behind it for a year. Here’s what each one looks like when you hire Fielding ADU West Covina.
Show up in the window. We give you a schedule window and we keep it. If we’re going to be late, you’ll know before the window closes. ADU construction in West Covina involves city inspections with their own timing, and we coordinate around them so the project doesn’t stall waiting on paperwork.
Price in writing. Before a single nail is driven, you get a written price. Not an estimate, not a ballpark, not a number we’ll “refine” once the walls are open. The written price is the price. Garage conversions, room additions, ADU builds: every project gets the same treatment.
By the book. We pull permits on every project that requires them, which in West Covina means nearly everything we build. ADUs and garage conversions have specific setback, height, and parking requirements, and we build to code, not around it. Our work is inspected and passes before we call it done.
Leave it clean. Construction is messy. Your yard shouldn’t stay that way. We clean daily and do a full site cleanup at the end of the project. You get your property back ready to use, not covered in drywall dust and cutoff scraps.
Stand behind it for a year. The Garrison Standard applies to every project we complete in West Covina. If workmanship fails within 365 days, we return and correct the defect at no charge. That’s the guarantee in one sentence.
How We Handle Prefab and Modular ADU Warranties
When you build with a prefab or modular platform, the structure itself carries a manufacturer warranty from the maker, not from us. We work with the major platforms a West Covina homeowner is already researching: Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, and Tuff Shed-style structures. Our role is installation, site work, foundations, and utility connections, and those are covered by our one-year workmanship guarantee. If a manufacturer component fails, we help you file the claim and we reinstall the replacement. You’re never left holding a warranty booklet and a phone number for a company in another state. Reed Calloway and the Fielding ADU West Covina team handle the coordination.
Why We Put It in Writing
We’ve seen what happens when a West Covina homeowner goes with the lowest bid and gets a verbal promise instead of a written guarantee. The conversation changes once the check clears. We decided early that our guarantee would be a document, not a handshake. The Garrison Standard has been building to that rule since 2006, and every Fielding ADU West Covina client gets the same paperwork: the price, the scope, the guarantee terms, and the process for making a claim. If something fails inside a year, call (559) 238-9583. A live person answers, the issue gets logged, and we schedule the return visit. That’s the guarantee, and it’s worth more than any slogan.
