It was super easy to schedule them. They came out to measure & then came out several days later once the replacement glass was ready to do the install. Left no mess behind & final charge was the same price as they originally quoted. Can't argue with that!

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. We chose black on white to assist those with visual deficits and really like how they turned out! The fold down seat is also a plus for those with endurance challenges! 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!!

This was a stellar experience from beginning to end!…read more We spoke with Amanda Rodriguez over two different visits and she could not have been friendlier or more knowledgeable. We had tons of questions and decisions about what best matched the original look of the windows from our 1939 house. We finally decided on what windows we wanted replaced and put down a deposit. A second team member came out weeks later to confirm the measurements. And some weeks after that, the installation team of Juan and Erik came out to do the install. (They even started by doing the measurements a third time to make sure everything was correct! And it was.) They had told us that the job might take the whole day, but they carefully removed the old ones, installed the new ones and cleaned up afterward in only about six hours. It was a flawless experience. Everyone we dealt with was extremely kind, warm and knowledgable. And the new windows look stunning - while still matching the look of the almost 90-year old home. We cannot recommend them highly enough!

The door install was done so expertly by Chad who installed an exterior door with new frame, bottom sill and dog proof kick plate.

Really high quality oak door and hardware, not some cheap plastic or composite. This door will hold up to the weather and the doggies. Highly recommend, thank you.

No call ahead but came at 9:30am and said no air leaking, by putting a business card around the door frame.

The installation was fantastic, two great guys Devon and Dennis, came out and installed everything quickly and efficiently. Very professional, super-clean--it was all so easy we didn't even know they were here until they said, okay, all finished. They also gave us instruction on how to use the new screens, plus tips on things that might arise during normal use. We are so satisfied with the experience we are now considering adding additional screens, that's how good the entire experience was. Very nice, great knowledge and explanations, and a good value for the top quality screens and installation. We LOVE our new screens. Highest recommendation.

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.

Wow. Just wow. My sliding glass door completely broke and…read morewouldn't open at all. I called California Sliding Door at 7:30 in the morning, and they were at my house the same morning. They fixed the door, installed a brand-new lock, and replaced the casters; everything was done right the first time. The technicians were friendly, professional, and immaculately clean. They treated my home with respect and left everything spotless. The price was exactly as quoted, no surprises, and the work was as professional as it gets. I only have one sliding door, so I wish I had more work for them. But if I ever need a new door or any repair in the future, this company will be my first and only call. I wish more companies operated like this. I can't say enough good things about them. Bravo, California Sliding Door; you earned every star.

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.

If something happens on the installation of our second phase, and it's bad, I'll change my review.
