Heath Windows replaced our front door in 2016 and did such a good job that we asked them to install 18 windows in 2017. Once again, they exceeded our expectations in everything they did. Mark and James, the window fitters were amazing. They had very high standards and cleaned up after themselves every night. The sash windows installed are of a great quality and we noticed a difference immediately, including lower energy bills in the winter. Our initial contact was Miall, who is great and dealt with all our queries really promptly, which sped up the whole process. We have nothing bad to say about this company!!
