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.

Castle Windows and Doors provided us with excellent service from start to finish. Vinny, our salesperson was knowledgeable, professional and extremely personable.
The door arrived in a very timely manner and the instillation was smooth and professional.
I would highly recommend Castle to anyone looking to update and improve their windows and doors. I give them FIVE STARS!

We had a very good experience from initial consultation to installation. The customer service has been excellent and the installers (Israel and Edel along with their team) were prompt, efficient, courteous, and neat. The windows seem good quality and work well. We will use Castle Windows for our next project without question. Thank you Castle Windows!

I had my windows replaced less than 2 years ago and am ready to replace them. They were not installed very well. Within 2 years, water began to seep into the house from the outside. I requested a home warranty service but they have not started repairs in over 2 months. My home is on a busy road and the windows make the same noise when the windows is open or close. I am very disappointed with their product and service. I have already found other products to replace their windows. There are many shortcomings, especially in terms of installation.

I’ve used Castle Window in the past, and I was very pleased with both their product and service. From the initial consultation to the final installation, the team was professional, punctual, and knowledgeable. The quality of the windows and doors are excellent—durable, energy-efficient, and a clear upgrade in both appearance and function from what I had before. I appreciated how the installers respected my home, worked efficiently, and cleaned up thoroughly afterward. It’s been a solid investment, and I’d definitely recommend Castle Window to anyone looking for reliable window replacement with great customer service.

This is our third time using Castle windows. Needless to say we are very pleased both with the company and the salesman. Each time I have also had quotes from other companies. I like the fact that they are the manufacturer and installer so they accept full responsibility and warranty their work. They are also very responsive to questions and any repair if needed. The salesman Noam was also very pleasant. He was very professional and we didn’t feel pressured. He took his time and explained everything clearly. I would highly recommend Castle Windows.
