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!!

We had two projects with Scotty: replaced our closet doors (trifold and bifold)and added a door to our den.

His team is very respectful of your home and the nicest people you'll meet in the business. And they were always on time! Worth every penny! We couldn't be happier with our doors and it was a pleasure working with Scotty and his team.

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!

When we hired The Window Factory in October 2024 to install a custom French door with sidelites, we…read moreexpected a premium product backed by professional workmanship and warranty support. Instead, we experienced nearly a year of delays, shifting explanations, broken promises, and unresolved warranty issues. The installation was originally promised for January 2025. It didn't occur until June 3, 2025--nearly five months late. Unfortunately, the door arrived with multiple defects that we documented immediately, including a dented frame, paint defects, improperly finished grids, damaged weatherstripping, and screen frames whose paint began peeling during normal wiping and cleaning. To be fair, the subcontractors who performed the structural opening modification were professional and did quality work. Our concerns have never been with them. Our concerns have always been with the condition of the product itself and how The Window Factory handled the problems afterward. We reported every issue on the day of installation. We were assured a technician would be out within a week. That never happened. Consultant James later confirmed the repair items had been approved under warranty. We believed the company would stand behind its product. Instead, weeks became months. Timelines repeatedly changed. We were told repairs were delayed because the company was "waiting on parts." Eventually, after months of waiting, technicians finally returned in November 2025. Despite all of the prior explanations about waiting for parts, no major replacement parts were installed. The visit consisted primarily of cleaning drain/weep holes, replacing some weatherstripping, adjusting one interior lock, and using the same bottle of touch-up paint that had already been left at our home months earlier. The dent remains. The paint and finish defects remain. The screen frames continue peeling during normal cleaning. During that visit, one technician acknowledged the ongoing screen issue and said the office would follow up regarding replacement screens with the factory-applied baked finish we had originally been told they would have. No one ever contacted us. The previously discussed refund was never honored. Our follow-up emails went unanswered. More than six months have now passed since that November visit without any meaningful follow-up. What has disappointed us most is not simply that a product had defects. Manufacturing problems can happen. What matters is how a company responds when they do. Throughout this process we tried repeatedly to resolve the matter privately. We accepted compromises. We continued giving additional opportunities to correct the issues. We remained patient through months of delays. Unfortunately, the communication became increasingly inconsistent, commitments were not fulfilled, and the matter was ultimately left unresolved. We paid more than $10,000 for what was represented as a premium custom installation with warranty support. Instead, we were left with a damaged product, unfinished repairs, unresolved warranty issues, and a company that ultimately stopped following through. Our hope is that sharing our experience helps future homeowners make a fully informed decision before signing a contract.

I had a call with Chris in which he said he would call me back with some answers, no call back. I called again, no further contact. This is NOT a company I would want to do business with when I can't even get a call back after paying a high quote fee with simple questions on a $30K job. Shameful to do to people. My advice is call around, good companies will come out and give the same type of quote Preferred did for free, and actually give you good business manners and call you back.

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.
