When we decided to remove our old patio doors and have them replaced with some new aluminium bi-folding doors, we invited three companies to quote for the work, one of which was yourselves. Whilst you were not the cheapest, from the start you were the most professional and really helped us make the right decision. This high quality service continued when you completed the installation last week, which went seamlessly. We have been extremely pleased with the quality of service from start to finish, and our new bi-folding doors look great. Yours sincerely.
