Chandra, Hove

I have had Velfac windows and external doors for 12 years. One window was not fitted properly by the developer (not Westcott) and had been leaking and needed replacing. The window was on a 4th floor flat and access difficult. Westcott were recommended by Dovista and Westcott worked timely from survey to order and then to sync with scaffolders dates to install. The guys had difficulty getting the frame up to 4th floor but they stripped it down and hoisted it up to the 4th floor. The job was professionally completed in a day. I am very pleased with the result and would recommend Westcott. Particular thanks to the boys who were all courteous and professional- Adam, Gavin, Matt and Andy. The office staff were always prompt with replies too. Thank you all.

We have worked along side Jeremy and his team for a number of years now and I can honestly say that you will not find a more professional, honest and hard working bunch of guys I would highly recommend them to anyone considering any size project.

When ordering the windows, we made numerous changes along the way. They were very quick to update the order and help with questions along the way. Their installation team was good and were able to overcome a few quirks in our existing house. I was doing the following on decoration works after the windows were fitted. A couple of aspects made it difficult to finish up around the newly installed windows. Shims and metal plates were left in need of grinding back in order to get a plasterboard back up against the window internally. This was perhaps inevitable however, due to the old Victorian check reveals in the brickwork and some very out of square existing openings. On the whole we are very pleased.
