Excellent service from Sureseal
The whole process with Sureseal from initial query to final installation was very straightforward with no surprises.
A really professional installation, Sean was both polite and efficient during the installation of windows and doors ensuring the home was left clean at the end of each days install.
We have recommended Sureseal to friends and have also received queries if who conducted our installation from a number of locals and have been happy to recommend them to Sureseal.

Good windows, Poor install
This process of having all new windows and doors started in March 25. They "installed" in August, three months later than promised. This was after we chased them. Its now mid November and I am having to get an outside contractor to finish the installation. The windows/doors are of a high quality but the installation on two of the biggest windows is below par. I complained to the original workmen who installed them and was told that it cant be fixed. After email tennis, two more senior installers came out and inspected. Hey presto the same men who installed originally returned and repaired what they said couldn't be repaired! Unfortunately being a Friday afternoon they just bodged the upstairs repair. Hence I am going to pay for another contractor to tidy it up. I cannot recommend this company unfortunately, If you are going to buy doors /windows for your whole house go and see some of the company you chose previous installs if possible. Do not believe all you read here or google. See for yourself. There are plenty to choose from.

Thank you for sharing your feedback, and we’re genuinely sorry to hear that your experience hasn’t reflected the high standards we set for ourselves at Sureseal.
We’re really pleased you’re happy with the quality of the windows and doors, but we completely understand your frustration with the delays and the installation issues you’ve described. That isn’t the level of service we aim to deliver, and it’s clear we fell short in parts of your journey.
We appreciate you raising your concerns with us directly, and while we’re glad the team were able to resolve some of the issues on their return visit, it’s disappointing to hear that the finish still hasn’t met your expectations. This certainly isn’t how we want any customer to feel.
We’d welcome the chance to look into this further and see what more we can do to put things right for you. If you’re open to it, please get in touch with us so we can review the remaining concerns properly and work towards a resolution.
Thank you again for your honest review — we take feedback like this seriously, and it helps us continue improving the service we deliver.

Our Sureseal Doors and Windows Installation…
The Installation Team were friendly, professional, polite & courteous. I was impressed with how respectfully they treated our home's fixtures & furniture. They worked efficiently and left us 'all clean & tidy'. They installed our beautiful new windows/doors, front & back which have made a significant difference to us by way of warmth, insulation, aesthetic appearance & lower fuel bills, all of which were desperately needed. We're very happy & grateful 🙏🏻 plus we've also had quite a few compliments too. We would recommend them to others in a heartbeat because of the reasons listed above...
Thank you Sureseal 🙏🏻

If it looks’ smells & sounds dodgy’ then its dodgy
Sureseal came to give us a quote & we’re more than double the price of the previous company we had a quote from.
The chap who came who was there nearly 3 times longer than the one before was quite pushy with the sales pitch & talked down our previous quote by another company despite us not giving him the details of the company or the price quoted,
The whole visit was a waste of time’
But what triggered the visit from Sureseal was an online pop up from a third party organisation called eco funding solutions who apparently give discount supported by government discounts.
We saw no evidence of this as we were never told the price would be A: but because of the government aid it will now be B:
When we asked about this he said the £6000+ price quoted included the discount’ when we asked what percentage count that was he couldn’t answer & so we parted ways.

We’ve looked into this carefully but don’t have any record of a quotation or home visit under your name — it may have been booked under a partner’s name instead. As we can’t locate you as a customer, this platform is the only way we can respond personally.
Our quotes are always computer-generated, not handwritten, and we don’t use high-pressure sales tactics; our aim is simply to give clear, accurate information so people can make an informed choice.
We understand prices can vary depending on product quality, specification, and installation standards, but we’re always happy to provide a detailed breakdown to help with a fair comparison.
If you’d like us to double-check the details, please get in touch directly and we’ll be glad to look into it further.
