The Seedling ADU San Diego Guarantee
When we build an ADU, garage conversion, or home addition in San Diego, we put our name on it, and we stand behind it. Our 365-Day Done Right Promise is simple: if it’s not done right, we make it right. Every project we complete is covered by this promise, in writing. No fine print, no phone tag, no waiting until next quarter. You’ll have the coverage documented before the first crew member arrives, and it stays in force for a full year after the job wraps. That’s the guarantee we give every homeowner from Chula Vista to Oceanside.
What’s Covered
- Workmanship on every ADU, garage conversion, and home addition we build. If something we installed or constructed fails because of our workmanship within 365 days, we repair or replace it at no charge.
- The written price you approved before work started. Our guarantee includes pricing integrity. You’ll never see a surprise line item added after crews arrive, and any change to the scope gets documented and approved by you before we proceed.
- Brand-supported materials and installation. We work with Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie materials. When a manufacturer stands behind a product, we coordinate with them on your behalf so you’re not stuck navigating warranties alone.
- Interior protection during construction. The Cedarwell Care Promise is part of our guarantee. Shoe covers and drop cloths on every visit. Pet-safe products where there’s a choice. A photo of the clean-up before the crew leaves, every single day.
- The people on your property. Every technician is background-checked and uniformed. When we say a crew is coming to your home in Clairemont or Rancho Bernardo, you’ll know exactly who’s walking through your door.
- A live person on the phone. During an active build, you can reach a real human 24/7. No voicemail trees. If you have a question at 8:30 pm about plumbing rough-in, someone answers.
Our Satisfaction Promise
Here’s what actually happens if you’re not satisfied. The 365-Day Done Right Promise kicks in the moment you tell us something’s off. Ben Ortega, the owner, gets directly involved. You don’t get bounced to a call center or handed a warranty booklet and wished luck. We schedule a walkthrough, we look at the issue together, and we agree on a fix. Then we send our own crew back to make it right, on our dime.
This isn’t a hypothetical. On a garage conversion in La Mesa, a finished wall showed hairline cracking three months after completion. We came back, diagnosed a framing issue, corrected it, re-drywalled, re-textured, and repainted. The homeowner paid nothing. That’s the promise, and it’s why we put it in writing instead of just saying it.
If something isn’t done right, we make it right. It’s the entire point of the guarantee. Call (858) 988-6447 if you ever need to hold us to it.
Licensed & Insured Backing

A guarantee is only as strong as the company behind it. Seedling ADU San Diego is licensed and insured, which means our 365-Day Done Right Promise isn’t just a verbal commitment from one person. It’s backed by actual legal and financial accountability. If we fail to honor our workmanship promise, you have recourse through the State of California. That matters when you’re spending five or six figures on a new home on your lot.
We carry insurance coverage appropriate for residential construction in San Diego County. Our crews work on your property, inside your home, near your family. Licensed and insured backing means you’re protected if something goes sideways. It’s the difference between a handshake and a contract. We provide both, and we’re glad to show you our credentials before you sign anything.
The only number you need is our phone: (858) 988-6447. Call it and ask to see our license and insurance documentation. We’ll send it over before the first site visit. No runaround.
