Overall the installation was good and the installers very professional, polite and tidy.
I did have an issue with the condition/state of the wall around the front door fan light, after installation was completed. However, Sureseal came to inspect and did a sterling job to rectify this.

Great Experience with Sureseal Windows Ltd
I’m very happy with the service from Sureseal Windows Ltd. They did an excellent job installing my windows and French door. There was a minor adjustment needed on the French door, but they quickly sent an engineer to fix the issue, which I really appreciated. The workers were friendly, professional, and respectful throughout the process. I would definitely recommend Sureseal Windows Ltd to anyone looking for quality work and great customer service.

Excellent service and great experience
We found Sureseal through an instagram ad for grants for old windows as our 1900s house still had the original single pane windows. One of their sales team came out to chat through our options, and one of the experts came to measure up. It took us a year before we decided to progress, but the quote had only increased minimally which was great.
The team started work on the Monday - two bay windows, a back door with windows and two other windows upstairs. It was a huge job as they had to remove the single pane wooden windows, and also not damage the original coving on the ceilings etc. they really did an excellent job of ensuring the finish was a decent quality, as well as installing really lovely looking (double glazed!) windows. Took them 3 days in total, so also a super quick job. They kept the house as clean as possible throughout too, so we didn’t have loads of cleaning to do after the fact.
Their service and aftercare in particular has been excellent. There were couple of minor things that needed to be finished off after they left, and the team were excellent at keeping in touch and finalising these things.
We were really keen to use a local Welsh company over the huge national companies, and I think because of that we got excellent service, really good quality and a good price.

Thank you so much for sharing such a detailed review of your experience with Sureseal. We’re delighted that the whole process—from your first enquiry to the final touches—has left you so pleased.
Working on a character property like yours with original single pane windows and delicate coving takes real care, so it’s wonderful to hear our team delivered the quality and finish you hoped for while keeping everything tidy throughout. We’re also glad the aftercare met your expectations—making sure every detail is right is something we take great pride in.
It means a lot that you chose to support a local Welsh company over the bigger nationals, and we’re proud to have delivered excellent service, high-quality products, and a fair price. Thank you again for trusting Sureseal—we look forward to helping you in the future if ever needed.

Lack of Communication & customer care but Great Installer
Ordered windows end of Feb, they have only just been installed (September). No updates throughout about the delays, I had to chase them to know they had an issue with one of the windows. Was supposed to be two person job for two days of work they said. The Friday before the start date on the Monday, told now a one man and four day job.
That guy, Alan, is the one saving grace for this company. Proper grafter, polite and friendly, also patient with little people asking questions. Done a great finish on all the windows and worked around our family life without issue.
Was binned us off after a further quote for more windows (as wanted to keep the style uniformed), going to look elsewhere.
*EDIT*- Since this post Sureseal have done the upmost to apologise and get to the root of the issues I experienced and been incredibly reactive to provide an affordable solution to a future window install quote. Even offering to co-ordinate with our builder (garage conversion on the cards).

New door and windows fitted.
We had our new door and windows fitted recently and couldn’t be happier with the service. The fitter arrived on time, was extremely professional throughout, and did a fantastic job with the installation. Everything was done efficiently and to a very high standard.
What really impressed us was how tidy he left the house afterwards! It made the whole experience stress-free from start to finish.
Would definitely recommend to anyone looking for reliable, high-quality door and window fitting.

Would recommend
The service was great throughout the process, from first consultation to fitting.
The person who came to talk me through my options was knowledgeable and talked me through all of my options.
I was working from a family home during the fitting of my windows and door, but was kept informed of the progress the entire time. When I went home afterwards, I was given my keys and advised that if there was any issues, not to hesitate to reach out.
I'm happy with the service and products received and I fully intend to use this company again when renewing the windows and doors at the back of the house!

High quality at an affordable price
Very pleased with our new windows and front door. The quality is first class - don't get me started on the ultra high security front door. I have had a lot of comments from passers going by my house! The fitting went really well and the fitters were great. Very friendly but professional and kept me up to date with the process along the way. Have recommended to friends.

First Class ...... We cannot speak highly enough of this…
We cannot speak highly enough of this company from first introduction with Jason the lovely salesman and the workmanship. No hard sell, we are too old for that nonsense!
Workmanship, clearing up as they went. Making good any plaster work.
And the product itself first class.
We cannot believe how much warmer our old farmhouse is now, no draught pockets or gaps and so quiet with the double glazing.
Thank you so much Sureseal Windows. 😊
