What stood out most was their attention to detail. They came out a couple of times before the install just to double-check and confirm all the measurements, which gave me a lot of confidence that everything would fit perfectly--and it did. The installation itself was clean and professional, and they made sure everything was sealed and finished properly. Communication was easy, and they were responsive whenever I had questions. Overall, I'd definitely recommend them if you're looking for reliable, detail-oriented window replacement work. I'd use them again for future projects.

Michael Crooks was very responsive as a company rep and everything he quoted was delivered just as he said. The quality of the shower is excellent and we love the Koehler fixtures.

The demolition andinstallation team of Jose, Gabriel and Jairo could not have done a better job! They were timely, efficient and professional. They demolished the shower and tub one day and took away all the debris. Then, the next day, they built the frame and installed the new walk in shower exactly as we requested. They were pleasant to have on our property and we're considerate in where they set up their workstation and parked their trucks. We did have a challenge posed by the installation day with company coming to visit us... And they worked out a mutually agreed upon date that met our needs. I highly recommend this company.. ask for this team of installers! You won't regret it!!

Cory led the installation and did an amazing job including rebuilding a bay window structure in the kitchen where the old wooden windows and wood framing had years of water damage that needed to be removed and rebuilt. Other companies that bid on this job did not seem concerned about the water damage in the bay window structure and wouldn't commit to exactly how far they could go to restore the integrity of this structure. Armond, came to meet with me and help me choose the right windows (from Milgard). He listened to my concerns about the kitchen window structured and assured me that Cory had the experience and skills needed to do the job right. Katie and Rio in the office were a pleasure to work with as well and answered all questions promptly with regard to order status, logistics, and billing, and the overall experience was beyond my expectations. Our neighbors on the next street were impressed with the job and hired Mighty Builders to replace their windows as well. I also have 2 close friends who need windows and will be reaching out to Mighty when they're ready. The finished job looks fantastic and I'm extremely happy with our new windows. I highly recommend Mighty Builders to anyone looking to replace windows at a fair price.

We were initially a bit concerned about moving away from custom doors, but we chose the wider bevel option, and they look great. We were very impressed with the efficiency and installation of their product. Nine years later, these vinyl sliding doors have had no issues, aside from tightening the handles once. They weren't the cheapest or the most expensive option during our research, but they've proven to be reliable and well worth the cost. Recently, we needed to repair one of the screens after our pet ran into it, and their team was very accommodating in helping us out. The staff, especially Heather, were friendly and a pleasure to work with. Thank you!

We purchased all new Milgard windows from SCV Glassworks in 2009. They have a lifetime warranty,…read moreand two of the windows are crystallizing on the inside, creating a foggy appearance. I called SCV Glassworks and first spoke to Eric and then to Andrew. The first response from Andrew was that they would replace the windows only if we purchased them "within the last year or so." I reminded him of the "Lifetime Warranty," and then Andrew said we had to file our request with Milgard. I pointed out that we purchased the windows from SCV Glassworks, and they hold themselves out as a "Milgard Certified Dealer." Andrew then changed his story and said he'd file a warranty request to Milgard to have the windows replaced. Andrew requested that I photograph the window frame and send it to him since it contained all the warranty information he needed. I forwarded the photographic information, and he confirmed receiving all the information he needed. He said he would put in a warranty request for me. After three weeks, I heard nothing, so I sent a text to Andrew asking for an update on my warranty request. He responded that he'll check with the manufacturer, Milgard, to determine the status of my warranty repair. He'd let me know as soon as he hears from Milgard. Two weeks went by, and not a word from SCV Glassworks, so today I decided to call Milgard myself. I reached Milgard's warranty department, and they advised that they had no warranty request from SCV Glassworks. Alexander, in Milgard's Customer Service Department, advised that it was best for me to just file my own warrant request through his department. Alexander asked that I forward the photographic information of the two windows to be replaced. I sent the information to Alexander, and in less than an hour, he confirmed receipt of my information, confirmed the warranty, and scheduled the window replacement. The Bottom Line: Milgard windows are great, and their service department is the best I've ever experienced. Kudos to Andrew in Milgard's Customer Service Department in Simi Valley. SCV Glassworks: First, a denial of a warranty, then a claim that they filed a warranty request when they had not, and no follow-up whatsoever. Their "service" was the worst.
