Used twice now and both times been efficient from quote to install. Best price I managed to get. Finish of the windows is fab. 1st set of windows went a bit stiff and needed adjusting they came out with no issue sorted them all within 10 mins great aftercare thanks

Seal lite have just installed our whole house with 15 new windows, 3 doors and 2 bifold windows. The whole experience from quotation to final completion has been extremely professional together with a great product offering. The quotation process was extremely thorough and gave us great confidence we were buying from a reliable company. We didnt have to wait an unreasonable time for installation and the provisional date was honoured.

The fitters were exceptional, turning up on time and treating our home with the upmost respect as if it were their own. The guys had a huge amount of pride in their work and as such every window and door was finished to the highest standard. We chose Residence 7 for our windows and they have transformed the look of the house both inside and out.

Residence Windows installed . Absolutely lovely company to work with . From the initial quoting stage right through to the installation everyone I had had contact with were helpful and very easy ti communicate with . Any minor issues were immediately resolved without hesitation . Thank you sealite group

Excellent customer service, and everyone we dealt with was competent and efficient. Communicated issues well, and rectified the few small problems on what was a big job with no fuss. Product quality first rate, and exactly as expected (no nasty surprises!) Overall, very pleased with the entire job.

The fitters arrived at the agreed time. Both were very polite and friendly. Worked methodically and got the new windows installed in the conservatory quickly, leaving everything clean and tidy. Would highly recommend Seal-Lite Group

Seal-Lite are always sensitive to our requirements and work exactly to schedule. All their employees are a pleasure to work with and I would recommend them to anybody.

Wed had our front door replaced a year or so before and were impressed with both the product and service. We choose them to replace the windows. All staff were helpful and professional. Absolutely no pressure from them at all to proceed and infact after the initial quote they left it completely up to you to decide if and when you wanted to proceed. Both jobs were carried out professionally and they left everything really clean, even putting our lounge and bathroom blinds back up for us.

We were both working and felt so confident with the company, we left left the installation team to it in the house. Both my parents and neighbours have been equally pleased with work they have carried out.

The whole process from start to finish was so easy. No pressure sales with everything clearly explained. This continued with the survey from Matt which was thorough and professional. As for installation, our fitters Kev and Steve were great. Everything was finished to a very high standard and everything cleaned and cleared before they moved onto the next window/door. Before they left they checked that we were happy with everything and were always courteous and professional. Overall wouldn't hesitate to recommend.

Fantastic service! New composite front door. From start to finish everything was so professionally handled - from initial contact, measuring up appointment, installation and follow up. If only all my house renovations had gone as smoothly! Id definitely highly recommend this company - and will definitely have them fit new double glazing when Im ready. Thank you Seal-Lite!

We called Seal-Lite this afternoon for advice as one of our 4 year old Seal-lite window handles broke! We were called back by a service engineer within 10 minutes and he was here within the hour to replace it!
Wow - well done Seal-lite, you reminded us why we came back as 2nd time customers 10 years on! Wish more companies were as responsive and helpful as you! Thank you

I would Highly Recommend this company !

Nothing much too much trouble, they arrived on time and worked very hard in the extreme heat and did a cracking job with a lot of care and attention to detail. Thank you ! I would Highly Recommend this company !
