Weeks after completion and paying for conservatory, we are still trying to get an aftercare engineer to look at the 'cosmetic' problems. The excuse is covid and people isolating. But this is weak, as it's approximately a twenty minute or so job to affix the plastics on the end properly and affix the end of the guttering firmly. The chap concerned is either on a job or on holiday, which is the excuse he came out with for last week. Not phoning to even try and set a time to come. We won't be purchasing any more products we intended to buy from this establishment.

Replacement windows, door and conservatory. Easy to get quote and survey. Fitters Greg and Kevin were excellent, friendly, polite and professional. Did an excellent job. Also had a recent issue with previous job done by the company and despite the time lag since installation, this was resolved to our satisfaction

Over the last 2 years we have had Superseal for new windows and french doors,
We Recently have had Superseal Build us a new Conservatory with Bifold doors which we think are great,
The whole team have been fantastic, and when we have had a issue ( which is understandable with this type of build) they have been out the next day to solve any issues. Would highly recommend Superseal.
