New Window and Window Swap
Had Global swap an existing window for a new bi-fold door and install a completely new window in our dining room. As hoped, both have created a lot of addition light. I have used Global in the past and would use again in the future. Professional service provided from the office staff. They were the only business I spoke to that was aware of the new building control regulations that were introduced at the start of October last year and therefore acted as Principal Designer keeping the works compliant. The guys that completed the work were very respectful, polite and tidied up after themselves. Would recommend.
