Do not hire this company!

ZERO STARS! Unfortunately, that’s not an option.

I would strongly advise anyone considering Castle Windows to THINK TWICE before giving this company your business.

The quality of the installation and workmanship is absolutely disgraceful. My windows were installed and caulked so poorly that my THREE-YEAR-OLD GRANDSON could have done a better job. I’m not exaggerating.

What’s even more infuriating is that Castle Windows proudly advertises guarantees and makes promises about standing behind its products. But apparently, those guarantees are only good when it’s convenient for them. When there’s a problem with their workmanship, they don’t want to take responsibility or honor what they promised.

It’s easy to make promises and collect thousands of dollars from customers. It’s a completely different story when it’s time to stand behind your work.

A company’s true character isn’t demonstrated during the sales pitch. It’s demonstrated by how it treats customers AFTER it has their money. Castle Windows has been a tremendous disappointment in that regard.

I expected professional installation, quality workmanship, and a company that honors its guarantees. Instead, I got shoddy work, frustration, and the feeling that once they had my money, they simply didn’t care.

DO YOUR HOMEWORK BEFORE HIRING THIS COMPANY. Don’t be fooled by the promises and guarantees. Based on my experience, I would NEVER recommend Castle Windows.

If I could give them MINUS FIVE STARS, I would!!!!!!!

was researching window companies and must have clicked something on a website and now I get at least five calls a day from Castle all from different phone numbers and all flagged as spam. After answering the phone and telling them I am not interested, I then received four more calls today within the span of 5 minutes. Even if I wanted to replace Windows, I would never go with them because of the harassment, I'm ready to call the police

I had a gentleman named Alex and he had a helper but I dont know his name. But Alex did an amazing install and helped me with any questions I had. His helper did well helping him with what he needed. I would love Alex to install my next set of windows when I save more money.

Damaged windows were replaced efficiently by their staff named ELI. He is very professional and did his job well.

Would Highly recommend Castle Windows.
The windows are high quality at a reasonable price.
The service was excellent, professional and friendly.
We love our windows, thank you.

Don’t trust the salesman,he tells you great things to get a sale,then you find out the truth. Be very careful with this company.

The Rep. Gerald James of Berlin, Md was great! He guided me through the process easily and seamlessly. The installation team drove 3 1/2 hrs to get here, and the door that was installed is perfect. The crew wouldn't leave until I gave them a "Thumbs Up" of approval. Will use in the future

Kevin did an awesome job with the best of his knowledge and expertise!!!!!Good things come to those who wait!!!! My window was finally fixed with a very skilled and efficient technician 😃👍

Overall, can't recommend them. The salesman lied to us on a couple points, the windows themselves seem like pretty standard quality, so if you can get a better prices elsewhere, you might as well do that. There were scratches and spots between the panes on almost every pane, so almost all of them had to be replaced. Meanwhile, they kept pushing me to make the final payment before the job was done, which I did not do. So there you go.

I put windows in 2 homes 2025 2nn 2026 completely satisfied with the workmanship and the craftsmanship of the company and its workers neat clean and efficient. couldn't be any happier

came to house on time was very careful while working in the house and just did a great job overall.

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.

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.

Thank you guys and keep up the good work.

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.
