I initially got my front and back doors replaced by Sure Sealed and they made such a good job I decided to get them to replace all my windows. The process from start to finish was very straight forward.

Initial sales meeting was to find out what I needed and there was no hard sell. Job was very reasonably priced and quality and finish of work was excellent. I have more jobs planned for Sure sealed. Would definitely recommend.


Fantastic service

Fantastic good quality service. 3 guys delivered the door and had it put in quickly leaving no mess.

Would definitely recommend.
