When my HOA got me on their annual inspection to fix or replace the French Door out to my patio, several friends advised me to include Castle Windows in my search for the right people to do the job. Boy were they right. From the product, to the process, to the installation to the warranty…I give them an A+++. They were always on time or early to respond and deliver. Their installation team was top notch and extremely professional. And the finished product is everything I could ask for. PLEASE… when you are in the market for windows or doors, put Castle at the top of your list of
Contacts to do the job. You won’t be disappointed. Thank you team Castle!

We had a great experience with this company. We are a repeat customer. The sales person that came here, Roberto, was amazing. Made you feel very comfortable and confident in the product that we were gettin.There was never a pressure to sign a deal with them. The presentation was one of a kind. He made the whole process. We signed with them and cant wait to see the finished project.

What I like about this company and why I would use them again is that they stand behind the quality of their products and services. I had a big window job and replaced over 20 windows and 2 sliding doors. The windows are high quality and beautiful, but the installation was less than satisfactory. They left my house a mess. The took apart a sectional couch and left it disassembled in the middle of the room. They moved my outside patio table and chairs and did not put them back. They took all of my daughters toys and loaded them all on the bed. Piled toys and dolls inside of my twins playpen. There was also empty cans left around the house and caulk on the carpet. Everyone makes mistakes. But it was how Castle Windows responded to those mistakes that will make me a repeat customer. The GM Robert was so upset about the feedback and took it personally. You could tell he took pride in the company and this was not their installation standards. When speaking to him I felt heard and truly like a valued customer whose experience mattered. Without hesitation he made it right for us. He sent over manager Brad to assess the situation and they were quick to fix any issues, including having my carpets cleaned to remove the caulk, wiping down the windows and sills, putting my couch back together, and doing some paint repair. It is rare to work with a company that shows so much pride and thoughtfulness when working with customers as Castle Windows does. Even though it didn't start out great, they delivered on their customer recovery. I am happy I chose them for my job and when I'm ready for a new front door they will be the first I call.

I love their windows and doors but. We called Castle to have someone repair my door multiple times. They kept canceling appointment's. When someone finally came out, we were told they could not fix the issue because they were not an "installer". I would not recommend this company. Lifetime warranty....... they will not fix the original product that was installed. For the price of the door, we should not have these issues. Will they take responsibility if my House gets robbed from the front door not working?

In June 2022 we had Castle Windows replace every window in our home. While we encountered a few issues, they were all rectified to our satisfaction in a somewhat timely fashion. In our experience, Castle Windows’ customer service was wonderful. A person answers the phone every time which lessens the frustration of dealing with automated systems. This is quality customer service. We were so pleased with our experience that this year, 2024, we decided to have our patio & front doors replaced. With the exception of the mis measurements of our front door and trim, we were equally satisfied this time around. They were on top of correcting the issue and beautifully installed the correct sizing of the Fypon door trim. Jose & Gary are top notch installers. They are meticulous, thorough, & professional.

Worst customer service and the window quality is poor. Besides the fact that we can feel the wind blow right through the glass of the windows, we've been struggling to lock half of the double hung windows they installed.
Customer Service: Once we finally got around to calling them about the lock, Kim, the customer service rep was rude, abrupt, and unprofessional. Did not take accountability for the fact that her driver was late, did not keep me informed, I had to initiate every call, and didn't apologize once.
Window Quality: The service person Kevin was nice, late, but professional. He said the issue is that we've left the windows unlocked too long, so now it's difficult to close them. The solution is keep the windows locked so that it could be accustomed to being locked. Wish I was kidding but no lie.
Windows are going to cost you whether its high quality or Castle Windows, so my recommendation for you is to err on the side of quality and stay away from castle windows.

Claims to have a life time warranty on it's windows for parts and labor. Trying to get them to fix my windows for over 4 months. They came once with the wrong parts. Numerous phone calls and e mails after go unanswered. Very disappointed with this company and false warranty.

This should have been a straight forward roof replacement, side and front windows an French doors. It ended up as a catalogue of incompetancy and a lengthy completion period. A father & son from Datchet were the sub- contractors they used for the dismantling and main build. Supposedly ex- Everest Windows installers, no wonder the company went bust. Their quality of work was appalling. Large gaps in the finished conservatory frames which you could see daylight through and let in water. Lead flashing that didn't meet current specification. Damaged window cills. The plasterer was no better and Castle had to hack off several large areas and re-plaster. I made it clear that I didnt want the original sub-contractors back. The workmanship in the re-routing of the kitchen extract fan was shocking. Castle Windows mis- measured the side windows not once but twice. I had many visits by Castle contractors between the end of August 2024 and end of November 2024 having to repair and make good the shoddy workmanship. Not once during this time did I receive an apology from the company nor a visit from one one of their senior people to look at the issues. This was despite numerous emails and phone calls. I was basically acting as their site supervisor/project manager who oversaw the work and flagged up problems for rectification. It was only when it came to the request for final payment that I received some form of veiled apology. The end result is ok and I appreciate that much of the problem was caused by rogue sub-contractors, but Castle Windows could have done so much better with their customer service.
