Start to finish positive experience of door and window replacement in new home
Sureseal replaced all our windows and doors in our new home. From start to finish they have been fantastic, from initial consultation to the surveyors visit to the fitting, everyone has been extremely helpful and professional as well as punctual and friendly.
A special mention must go to our fitter Jamie. He did a fabulous job, worked swiftly and unobtrusively. He was punctual , polite and cheerful and left no mess. He was also very mindful of our many dogs and was very considerate when working near them.
We are delighted with our new doors and windows, they have exceeded our expectations and they have really transformed the appearance of our house.

Excellent service and fitting
We have just had our windows and doors fitted. It's been a great experience and has given our home a whole new feel.
Our previous windows were fitted in the late 1980s and had degraded badly. These new ones are great.
The window fitters, Alan and Ben, we're great and nothing was too much trouble. They finished well ahead of schedule and left us with a whole new look.
We're very pleased and thank you.

My experience with Sureseal Windows Limited
I contacted Sureseal Windows Limited in early November 2025 to request a quotation for new windows and doors in my bungalow. I had a visit from Neil, who went through all the options and the build quality of their products. There was no hard sell and I thought the price was very competitive. I accepted their quotation and I then had a visit from Rob, the Surveyor, to double check everything and confirm exactly what I'd decided on for each window and door. The work was done last week over 3 days by James Henderson, whose workmanship, attention to detail and friendly manner I could not fault. He was friendly and polite and discussed with me what he was planning to complete each day and remained cheerful even when the rain was sometimes incessant! The results are absolutely beautiful and excellent quality and I would have no hesitation in recommending Sureseal Windows Limited. I was also very happy to be using a small, local South Wales company and when I contacted the office I found that Richard and John were very helpful and accommodating.

James the fitter was great 👍
From the start to finish this company were amazing.
From Jordan who gave us price, the surveyor I think him name was Rob sorry can't remember. Richard in the office was great phoning and emailing to keep us up to date of the going ons. But most of I would like to thank James the installer who worked his nuts off fitting 3 windows and a new front door. He was polite and we had a bit of good banter with him. He was very professional and cleaned up after him. He did a marvellous job and finish to both door and windows.
We are very pleased with the outcome and quality of our items I will definitely recommend sure seal windows ltd.
P.s tell James run out of sausage buttys.

Thank you so much for such a brilliant review — it really means a lot to us.
We’re delighted to hear you were happy from start to finish. Jordan, Rob and Richard will all appreciate the mention — keeping everything clear and well communicated is something we pride ourselves on.
And James… we’ll definitely be sharing this with him! He always gives 100% on site, so it’s great to hear his hard work, professionalism and tidy finish didn’t go unnoticed — along with the good banter of course. That’s exactly the kind of experience we want our customers to have.
We’re thrilled you’re pleased with the quality of your new windows and front door, and thank you for recommending Sureseal — that support genuinely helps a local company like ours.
P.S. We’ll make sure James knows about the sausage butties situation… he might start bringing his own next time!

Sureseal are the best! Sean and James were brilliant
Sean and James were brilliant, really enjoyed having them around. They were polite, helpful and professional. They cleaned up after themselves several times a day and did an excellent job. Fantastic company, trustworthy and wouldn't go anywhere else. Brilliant aftercare service and they're happy to come out again if required under the warranty. Nothing is too much trouble for them. Well done all of you and your guys in the office, Rob the surveyor was fabulous too. Highly recommend, stellar company!!! Xxxxx
