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Our surveyors sometimes highlight areas of concern such as energy loss or outdated security – particularly when asked – with the aim of being transparent and helpful, never to cause unnecessary alarm.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.
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.

Amazing service, quality windows and excellent installation
Windows were fitted very quickly and professionally. Lovely finish. Some extra building work was done to lower height of window and block a window up but this was all accommodated within the service. Very helpful.

Excellent from start to finish
From the first visit through to measuring, delivery and installation we cannot recommend them enough. We were offered relevant information without any pressure. The delivery time was good considering the Christmas break was in the middle. Mal and James installed 8 windows over 2 days. They worked without a break and there was no damage or mess. They even matched the cement to our existing stonework. That attention to detail tells me how that they really know their stuff. Thank you to the whole team at Sureseal Windows.

Sureseal.
Sureseal.. What a fantastic reliable company, from start to finish. When enquiring about my windows and new front door I was dealt with by an amazing team, who then came out the following day to show me what style windows I could have, talked me through everything, measured up and ordered straight away. The website was so easy to design my own front door to exactly what I wanted.
The fitters did an amazing job, and were very friendly, and most importantly tidy.
The noise difference with new windows living on a main road is amazing. I can no longer hear any passing cars, and no more drafts.
I would highly recommend Sureseal to all my friends and Friends. Thank you
