TIME WASTERS I asked for a quote from Interseal for replacement windows and instead a site visit, I was asked to send a photo for them to quote from which was strange enough. I then tried to contact them several times only to be ignored. Make your own mind up.

So pleased with my new windows Interseal fitted last week - they look great. Really impressed with the service provided by Interseal and being a Plymouth based business so easy to deal with.
