Not as good as they used to be !
Poor measuring from outset , had to recheck ourselves a number of times .
Our replacement windows are leaded which caused issues with getting them standardised so there is uniformity with plans before fabrication . We copied in the managing director when complaining about our apparent responsibility to check but had no response from the top only a phone call from someone from the fitting team admitting it was Seal lite's responsibility to get everything right !
On installation we noticed lead work wasn’t straight on all windows .. which we had to point out and measure again. After no clear plan about who was going to turn up and when we had to wait a further few weeks for final installation after removal of the “wonky “ leaded windows .
This used to be an excellent company , prev past work was good however now it seems there is poor communication between fitters and very poor customer service . Blame was attributed elsewhere .. mainly to the company they used to fabricate the glass , delays again as even seal lite weren’t happy with the second attempt .
Overall we felt the “ two day “ job ended up virtually all week initially causing loss of earnings .. when they were finally correctly installed the token gesture of upgraded vents was appreciated as the first weren’t fitted correctly letting in more cold air than our old windows !
More understanding needed of customers time , disruption ( moving furniture etc ) and the stress of not knowing what was going on , various fitters seemed to going from one job to another with not enough time allocated .

Dear Mr & Mrs Sandy
Thank you for taking the time to share your feedback. We are genuinely sorry about your experience, particularly as you have previously had positive work carried out by us. It is especially disappointing to hear that on this occasion we did not meet the standards you rightly expected.
There is no question that accurate measuring, clear communication and proper coordination are our responsibility , nor should there have been uncertainty about attendance, delays, or who was managing the process. We also sincerely apologise for the disruption caused by the additional visits and extended timescale, and for the stress and loss of earnings this resulted in.
While there were issues with the glass supplier, that does not lessen our responsibility to manage the process properly and keep you fully informed throughout. We are sorry that you felt blame was deflected rather than ownership being taken.
We do appreciate your patience while the glass units were remade and refitted, and we’re pleased that the final installation met the correct standard. However, we fully acknowledge that the journey to get there was far from satisfactory.
Your comments regarding communication between teams, time allocation on jobs, and consideration of customers’ time and disruption have been taken very seriously. This feedback is invaluable and will be reviewed internally to ensure improvements are made.
We truly regret that this experience has affected your perception of the company, particularly given your previous positive history with us. Should you wish to discuss anything further, we would welcome the opportunity to speak with you directly.
Kind regards,
All at Seal-Lite
Extremely pleased.
Extremely pleased. We had Seal-Lite replace a couple of windows and a door over the past few years and were very impressed. The cost was competitive but the service and quality was outstanding. So when it came to replacing the rest of our 25yr old windows, knowing the service we had received, we went straight to Seal-Lite. The salesman was not at all pushy but explained everything. We placed the order and everything went very smoothly. The installation (4 windows) took one day and the installers were excellent. Very careful of the carpets etc and did an excellent job. I would not hesitate to recommend them highly.

Absolutely perfect experience
Absolutely perfect experience from start to finish.
From the moment we met Paul we knew that he'd be doing our windows. The product was great, his understanding of it, he listened to our needs, explained clearly what we could do better and why, and the process was quick, easy and priced fairly.
Then came the fitting! This was so smooth and the fitting team were quick, clean, and respectful. All openings were made good and all waste was removed from site.
We love our new windows and couldn't recommend Seal Lite more highly. Thanks to all involved.
