Arranged a visit/quote and Roy turned up on time and gave us a non-pushy estimate and details for us without his wider window knowledge.
Gave us a very decent quote and went with them.

Arranged the date & time and Roy kept us up to date with any developments by email.

Arrived on the day on time, did a great job fitting two windows in the morning and left the place clean and tidy. You can't ask for more really.

5/5 Stars. Would recommend. 👍

The team was led by Peter - great comms, double glazing patio door to insulate the ground floor bedroom, replaces single glaze door. After installation there was a slight problem but it was resolved in good time. Thank you.

Laurence Radford

Roy and team did an excellent and professional job replacing 3 front windows, making the change unnoticeable from the outside. They were worked with challenges getting large frames into the upstairs room and were courteous throughout. Would recommend.

Really happy I chose Southeast Windows to fit my UPVC back door. Roy was friendly, professional and helpful at every step of the process. I was very happy with the workmanship and it was done so efficiently and with so little mess. I definitely recommend for a first class service !

I would like to express my heartfelt thanks to Southeast Windows for their exceptionally good service. From the moment I reached out to them, their team demonstrated professionalism and efficiency that truly impressed me. The installation process of double glazing was remarkably fast, allowing me to enjoy the warmth of the new windows brought sooner than expected.

Moreover, I was particularly impressed with the cleanliness maintained throughout the whole installation project. The team took great care to ensure that my home remained tidy, leaving no mess behind. This attention to detail speaks volumes about their commitment to customer satisfaction.

Besides, the quality of the windows is outstanding. The windows not only enhance the aesthetic appeal of my home but also provide excellent insulation. I am thrilled with the results and would highly recommend Southeast Windows to anyone in need of window services. Thank you Roy and your team once again for your hard work and dedication!

Excellent work from Roy and his team. He installed our windows quickly and with a minimum of dust etc. They also took away the old windows which was a great help.

Roy replaced all the windows at the front of my house three years ago. This time I got him to replace a couple of blown windows in my kitchen. As before, he was efficient, courteous and excellent value for money. Communication was also outstanding. Very happy with the job and strongly recommend Roy.

Roy and his team fitted new windows and French doors in our house earlier this year (we wanted to live with them for a while before reviewing!). We are really pleased with the quality of the windows and the service from Roy. He's a real gent to deal with and is punctual and professional. His quote wasn't actually the lowest but he was the only one to supply full details of materials, give fire safety and security advice, send a detailed quote etc. Thank you Roy

I got quotes from a few companies however Peter was the only one who followed up to my questions on email so I decided to go with Southeast Windows. I am super glad I did, as Peter was professional and I am really happy with the work done in installing a new PVC backdoor and replacing glass in several windows. Peter was knowledgable, friendly and didn't take advantage of my lack of knowledge of window and door installation like some other builders have, being a first time home owner.

I wouldn't hesitate to recommend Peter and Southeast Windows, I will for sure be using them again if I need. Thank you Peter!
