10 Double Glazing Bay Window installation
Posted 25 February
I needed an old wooden bay window replaced with uPVC & requested a quote which was promptly conducted by Mitch with an onsite visit. He was highly professional & explained my options. I received my quote & proceeded to installation. The team arrived on the scheduled date & did a great job. I’m thrilled with my new bay window & the service received from the entire team - the product is robust, in addition to adding better insulation & noise reduction.Verified reviewerJob location: E1110 Amazing
