Excellent experience
We recently had all the windows and doors replaced by Sureseal. Initially, Neil came to see us to give us a quote. He was not at all pushy but was very friendly, polite and knowledgeable. He patiently answered all our questions and discussed different payment options with us. The installation went well. There were a couple of issues - one window was scratched but the installer noticed it and ordered a replacement immediately. This was then fitted as soon as it was ready. We have a large bay window with a big windowsill that is not a standard size. It was difficult to fit. Unfortunately, some of the adhesive left a mark on the sill. I informed Sureseal immediately and they sent an installer out to check. They rectified the issue to our satisfaction. Communication with Sureseal has been really good. All of the staff were polite and respectful of our property. Would definitely recommend Sureseal.

Quality windows & doors, excellent service provided.
I am delighted with my new windows and doors from Sureseal Windows. They are of excellent quality and have already made a noticeable difference with regards to maintaining heat, sound proofing and securing the property. Also, a very competitive price as part of the 'recycle our old windows scheme'. All correspondence from assessment to installation was professional at all times. Some of the team I dealt with, Gareth, Rob, Gary the fitter and the young lad working with him answered any questions I had and I always felt reassured and listened to. Jordan was excellent in going through the various products and available options to us and nothing was too much trouble. The fitters were extremely friendly, hardworking, neat and ensured all work was completed to a high standard with minimal disruption which was appreciated as it was very close to Christmas! Any minor concerns I had were rectified immediately by the fitters and the company have contacted me since checking that everything is still up to my standards. Would definitely use Sureseal in the future if needed and would highly recommend them.

11k for 9 windows what a joke
The company tried to to give me a quote of 11 thousand pounds to change 9 windows. And they were backed by a government scheme absolutely con. And tried to scare you into going with them saying that if someone really wanted to they could take my windows out easily

Thank you for taking the time to leave a review.
We’re genuinely sorry to hear that you were unhappy with the quote provided during your appointment back in November – over four months ago now. Understandably, with time passing, some of the finer details can be easy to forget, so we wanted to offer a bit of clarity.
The quotation given was £9,906.83, which included the supply and installation of nine fully steel-reinforced windows, each with an A+10 thermal rating, internal cills throughout, and scaffolding at both the front and rear of your property – essential for a safe and fully compliant installation in your case.
We appreciate that replacing windows is a significant investment, and pricing can vary greatly depending on quality, materials, and property requirements. That’s why all of our quotes are provided without any obligation, and we always encourage customers to compare and make informed decisions.
Our surveyors sometimes highlight areas of concern such as energy loss or outdated security – particularly when asked – with the aim of being transparent and helpful, never to cause unnecessary alarm.
If you’d like to discuss anything in more detail, our team would be happy to help. And if you feel this review may not reflect the full context, we’d really appreciate you considering updating or removing it.
Kind regards,
The Sureseal Team

Fantastic service from start to finish
Sureseal Windows replaced the majority of windows and our back patio doors, and installed a dog flap. They were very professional throughout the whole process and didn’t give us the hard sell. We got an excellent price due as they recycled our old windows. The installers Jamie and Mal were friendly and punctual. They worked hard to get the job done on time and were very neat. The new windows and door look great and we have already noticed the house is lighter, warmer and quieter. I would highly recommend this company.

Had 5 windows and a door fitted.
We were assessed a few months ago and placed an order, the salesman was helpful and honest and went well above and beyond! We required planning, which sureseal helped as much as they were able to. The fitters were really good, the job took longer due to some insulation work done in the previous year on a gov grant which was a complete botch job. This made it far more difficult for the sureseal guys, and too longer. But they worked hard and did a genuinely incredible job. We’re so pleased with the results. 100% worth it.
