Get your free estimateThe Lightwell Windows Pasadena Guarantee
We stand behind every window and door we install in Pasadena with one simple rule: if the finished work is not right, Lightwell makes it right. No debate about whose fault it was. No countdown clock on your claim. The 365-Day Done Right Promise is stamped on every job we take, from a single bedroom window in Bungalow Heaven to a full-home replacement in Linda Vista. Keith Yamada, Owner, built this company on the idea that a guarantee means something only when it’s tested. Ours has been tested. It holds. You get a written price before any work starts, a crew that treats your home like their own, and a phone number answered by a real person if anything ever needs attention.
What’s Covered
- Workmanship on every installation. If the finished work is not right, we make it right under the 365-Day Done Right Promise, with no debate and no countdown.
- Written pricing before work begins. A fixed, itemized price is in your hands before the first tool comes off the truck, so there is no invoice surprise at the end of the day.
- Your floors and furniture. Shoe covers and drop cloths go down on every visit, and a photo of the clean-up is taken before the crew leaves.
- Your family’s schedule. We follow the C.A.R.E. values on every job: Clean up like it is our own home; Ask before we move or touch anything; Respect the family’s time and quiet hours; Explain the price before the work.
- Parts and materials handling. We work with eight manufacturer brands, PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux, so the product we install is the right fit for your Pasadena home, not the brand we happen to prefer that month.
- Who shows up at your door. Every technician is background-checked and uniformed. You know who is arriving before they knock.
- Your pets and kids. We use pet-safe products wherever there is a choice, and we keep the job site quiet during nap time when we can.

Our Satisfaction Promise
Here is how the make-it-right process works if you are ever unhappy with a finished install. You call us at (626) 628-2308. A live person answers, not a recording. You explain what is wrong. We schedule a walkthrough with Keith or a senior crew lead, usually within a few days. We look at the work together. If the finished work is not right, we fix it. That is the promise. We do not ask you to argue your case. We do not point to fine print. We do not make you wait for a “warranty department” to review your file. The 365-Day Done Right Promise means exactly what it says. It has been our standing rule since Lightwell became part of the Cedarwell network in 2010, operating to the Cedarwell Care Promise on every job. Most issues are caught before we leave the driveway, because the crew does a walkthrough with you and takes a photo of the clean-up. But if something shows up a month later, a sticking sash in a Pasadena heat wave, a door that settled after the first rain, you call. We come back.
Licensed & Insured Backing
A guarantee is only as good as the company standing behind it. Lightwell Windows Pasadena is licensed and insured, which means you are protected before the work starts, not just after. If a crew member is hurt on your property, our insurance covers it, not your homeowner’s policy. If something goes wrong during installation, you have recourse. That is the real value of hiring a licensed, insured contractor instead of someone working out of a truck with a cell phone. The paperwork is not the guarantee. The guarantee is what happens when the paperwork is tested, and we have spent fifteen years making sure the answer is always the same: we handle it. Keith Yamada, Owner, has brought the Cedarwell Care Promise to every Pasadena job since 2010. That promise includes the clean-up photo, the shoe covers, the written price, and the live phone answered 24/7. None of it is optional.
