The Seedling ADU Pasadena Guarantee
We put our name on every ADU, garage conversion, and home addition we build in Pasadena, and that name matters to us. The Seedling ADU Pasadena guarantee is simple: if it’s not done right, we make it right. Every project is backed by our 365-Day Done Right Promise, in writing, before we ever pick up a tool. You get a written price before any work starts, a crew that shows up in uniform with background checks completed, and a live person on the phone whenever you call. That’s what standing behind our work looks like around here.
What’s Covered
- 365-Day Done Right Promise. If anything we built isn’t done right within a year of completion, we come back and make it right, no arguing, no runaround.
- Workmanship on every structure we build. ADUs, garage conversions, and home additions all fall under the same standard: built correctly, to code, with materials that hold up in Pasadena’s climate.
- Written pricing before work starts. The number on your written quote is the number you pay, with no surprise line items added after the crew arrives.
- Cleanup, documented. Shoe covers and drop cloths go down before we walk through your home, and you get a photo of the clean-up before the crew leaves, every visit, no exceptions.
- Respect for your family’s schedule. We use quiet tools where we can and plan noisy work around nap times and school hours when you tell us what your household needs.
- Background-checked, uniformed technicians on every job. You’ll know exactly who is walking through your door, and they’ll look like they belong on a professional job site.
- A live person answers the phone 24/7 throughout your project. No voicemail trees, no next-business-day callbacks during an active build.
- Access to the brands serious ADU buyers research. We work with Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie, so you choose the right product for your lot, not just what’s convenient for us to sell.
Our Satisfaction Promise
Here’s how it works if something isn’t right. You call us. A live person answers, because that’s how we operate from the first phone call to the final walkthrough. You tell them what’s bothering you, whether it’s a door that doesn’t close true or a finish that looks off in afternoon light. We send someone out to look at it, and we don’t make you prove you’re right before we take you seriously. If we got something wrong, we fix it. If you’re not happy with how a detail turned out, we talk through what it would take to make it right and we do it. Ben Ortega started Seedling ADU Pasadena because he got tired of hearing stories about builders who disappeared after the final check cleared. The 365-Day Done Right Promise exists so that story never starts with our name on it. We’d rather have you call us twice than have you tell a neighbor once that we let you down.
Licensed & Insured Backing
A guarantee is only as good as the company behind it, and a licensed, insured contractor is the real foundation under every promise we make. State licensing means our work is held to California’s building standards, and insurance means your property and our crew are protected if something unexpected happens on site. We’re licensed and insured, and we’re happy to show you that paperwork before you sign anything. The Cedarwell Care Promise is the operating standard across every Cedarwell location, and it’s part of what we put in writing for Pasadena homeowners: shoe covers and drop cloths inside your home, pet-safe products where there is a choice, a clean-up photo before the crew leaves, and a live person available by phone 24/7. The 365-Day Done Right Promise and our upfront written pricing are the promises we make. Licensing and insurance are what make those promises worth more than the paper they’re printed on.
What We Don’t Do
We don’t bury warranty language in fine print. We don’t make you track down a subcontractor to ask about a squeaky floor or a misaligned cabinet pull. We don’t treat your phone call like an interruption once the build is done. And we don’t start work without a written price in your hand. If a builder won’t put it in writing, that’s your first red flag. If they won’t answer the phone after final payment, that’s your second.
How To Use This Guarantee
Keep your written quote. Keep the paperwork from the final walkthrough. If something comes up within 365 days of completion, call (626) 657-5461 and tell us what’s going on. We’ll schedule someone to come look, and we’ll make a plan to fix it. That’s the whole process. No arbitration clauses, no thirty-day waiting periods, no automated phone system routing you to a call center. You call, we answer, we show up, we make it right.
Why We Put It In Writing
Ben Ortega has walked through enough half-finished ADUs in Pasadena, Altadena, and San Marino to know what happens when builders skip the paperwork. A verbal promise dissolves the first time there’s a disagreement. A written promise changes the conversation. It tells you, before you spend a dollar, exactly what you’re getting and exactly what happens if it doesn’t meet the standard. That’s why every Seedling ADU Pasadena project starts with a written price and ends with a written 365-Day Done Right Promise. A new home on your lot deserves that.
Common Questions Homeowners Ask Us

What does the 365-Day Done Right Promise actually cover?
It covers anything we built that isn’t done right within the first year after completion. That means workmanship issues on your ADU, garage conversion, or home addition, from structural details to finishes. If it’s our work and it’s not right, we fix it. Call (626) 657-5461 and we’ll get it scheduled.
Do you give a written price before work starts?
Yes. Every project gets a written price before any work begins, and that number doesn’t change because we found something unexpected once the crew showed up. We plan carefully because we build in Pasadena, where lot dimensions and set-back rules vary block by block. If you’re comparing builders, ask each one whether their price is written and whether they’ve ever added line items after starting. Then call us at (626) 657-5461 for your estimate.
What happens if I’m not happy with the work after the one-year mark?
Call us anyway. The 365-Day Done Right Promise is the formal guarantee, but we’ve been known to come back for homeowners long after the year is up because it was the right thing to do. We’d rather keep a relationship in good standing than hide behind a calendar. Call (626) 657-5461 and talk to a real person.
Who shows up to work on my ADU?
Background-checked, uniformed technicians, every time. You’ll know who’s on your property, and they’ll treat your home the way the Cedarwell Care Promise requires: shoe covers and drop cloths inside, pet-safe products where there’s a choice, and a clean-up photo before the crew leaves. If you have kids sleeping or a dog who barks at strangers, tell us and we’ll plan around it.
Do you pull permits and handle inspections?
We handle the permitting process for ADUs, garage conversions, and home additions in Pasadena, and we build to pass inspection. Permit requirements vary by project scope and lot specifics, so call (626) 657-5461 to talk through your property and we’ll tell you what’s needed.
How long does an ADU or garage conversion take in Pasadena?
Timelines depend on the project: a prefab ADU on a prepared foundation moves faster than a custom garage conversion with structural work. What we don’t do is rush. Our promise is care and accuracy, not speed. When you call (626) 657-5461 for your free estimate, we’ll give you a realistic schedule based on your lot and your scope, in writing, before any work starts.
