  • Hamilton's installed bi-fold doors for us early this year and also carried out some repairs to existing windows in our house. The overall service was excellent with the work carried out to a very high standard by very friendly fitters, and whenever I dealt their office staff they were equally helpful and efficient. Highly recommended!

  • Outstanding service, friendly. professional and very accommodating. We will be using Hamiltons again. A big thank you to everyone.

  • From the very first communication to the final fit of our windows and doors, our experience with Hamilton was exceptional. We had all our windows and our front door replaced through Hamiltons and are extremely pleased with the end result. Everyone we met from Hamiltons were always professional and honest and it never felt like a hard sell.  The workers were clean and tidy during fitting with dust sheets and at the end of each day you hardly knew workers had been in. The windows and door look amazing, and we are so pleased. We have had compliments from all who visit and have recommended Hamiltons to all our family and friends.

  • Hamiltons were absolutely brilliant. Not only did they come in cheaper than 2 other quotes I had but they managed to replace all of the windows and doors within 2 days (by working long hard shifts). They took away all of the old rotten wooden windows and tidied up everything so you wouldn't have known that they had even been there!
    Cannot recommend them highly enough to anyone else wanting their tatty windows replaced or in my case, a back door that you had to kick to open!

  • From quote to install there was a good communication flow and solid no-nonsense advice. The finished product, aluminium windows, is as well engineered as it is beautiful to look at. The installers were very skilful and courteous. My thanks for a job well done.

  • I have used Hamilton Windows on a couple of properties - whether the job is large or just a single window I feel I get the same attention to detail and reliability.

    That seems rare in this trade but is what will get me back to a Hamiltons again in 2018.

  • Excellent product quality, pricing and professionalism! From requirements analysis to quote and installation, the process was very smooth and without any hardsell. Found them much better than the big name window companies we've used in the past.

  • I recently had all my windows and doors replaced by Hamiltons. From the first point of contact through to the installation everyone I dealt with was polite and professional. The quote was very competitive and the installation went without a hitch. I would highly recommend this company.

  • I would highly recommend Hamilton Windows and Doors to everyone. The service we received from them from the initial 'phone call, the survey and quote, and the installation was exceedingly professional, friendly and helpful. The windows and doors are very good quality and the installation was of a very high standard. Any queries I have raised have been answered quickly and well and the after-sales care has been brilliant.

  • Excellent service, all the staff are incredibly helpful and they have fitted windows and doors for me both at home and at my office which I am very happy with. Would highly recommend.

  • Very pleased with the installation. Professional and easy to deal with. Very happy to recommend this local business!

  • As a builder doing small extensions, I use Hamilton Windows for all of my clients' glazing projects - from bi-fold doors to skylights to double glazing. I have used them for over 10 years and they have never failed to impress me. The installers are always on time and my clients' are really happy with the end results.

  • I've recently used Hamiltons to replace my windows and doors, the products are great and the staff are very friendly and professional. I wouldn't hesitate to recommend them.

  • Everybody we dealt with was friendly and professional, Pricing was competitive and lead time from ordering to installation was very impressive. Highly recommended.
