Écrit par l'entreprise
Sureseal Windows Limited delivers class-leading home improvements with a focus on quality, clarity and care. We design, supply and install premium windows, bi-folding doors, sliding doors and entrance doors, completed by robust rainwater protection systems (roofline) to keep your home looking sharp and performing at its best. Every product is specified for lasting performance—smooth operation, secure hardware and excellent thermal efficiency—so you feel the difference from day one. Your home is unique, so our approach is personal. We’ll help you choose the right styles, colours and finishes, from slim-sightline contemporary looks to timeless classics. Our designers listen first, offer practical guidance, and provide clear, transparent pricing. No pushy tactics—just expert advice and options that fit your home and budget.

Aftercare is straightforward, too. You’ll have honest communication, dependable warranties, and a friendly team on hand if you ever need support. Whether you’re replacing a single door, opening up a view with bi-folds, upgrading to energy-efficient windows, or completing the look with roofline products, we’re here to make it easy—and to do it properly. If you’re considering improvements, we’d love to help. Book a free, no-obligation design visit and see what’s possible.

Very very please with the work carried out from start to finish. Very professional service. Jordan was great with the initial quoting and showing me the options, and he was always on the end of the phone if I wanted extra info. When it came round to the fitting I was contacted way ahead of installation to find a date that worked. I cant remember the names of the lads that came to fit the windows, but they did an excellent job and left the work site clean at the end of the day.

We had replacement windows fitted in…our experience
We had replacement windows fitted in May of this year. We had not previously dealt with this firm before because they were not local to us. We found them helpful and informative from the start. Their fitter was outstandingly good. There was one minor issue in that they overlooked one part, a windowsill. Which although not urgent was fitted within two days. We were delighted with the result.

Thanks Sureseal Windows and thanks for sending Sean our way who has done the best job ever The Coles family are very happy indeed.

Absolutely amazing company went above and beyond in every way possible, from the first appointment to help with what we wanted and what was best but also in our price range to fitting in an efficient manner and the after care of checking up on how the client is getting on with the windows and doors installed is fantastic, over a year on and the product is impeccable with no problems whatsoever.
Definitely recommend.

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).

Thank you for taking the time to share such a balanced and detailed review. We’re genuinely sorry for the delays and lack of communication you experienced earlier in the process—that isn’t the standard of service we aim to deliver, and we fully understand your frustration.
We’re really pleased to hear that Alan made such a positive impression with his workmanship, professionalism, and the way he worked around your family. He’ll be delighted to know his efforts were appreciated.
We’re also grateful for the chance to put things right following your feedback. Our team is committed to learning from this and ensuring communication is stronger moving forward. We’re glad we could revisit your project, provide an affordable solution, and even coordinate with your builder for your future plans.
Thank you again for your patience and for allowing us the opportunity to restore your confidence in Sureseal.
