Prior to initiating the repair (to the inside of) our north-facing front window, the contractor we hired advised us that in order to provide long-term integrity for what would be a superb job on his part, the second-floor and main front windows would have to be properly insulated and re-sealed. To the Yellow Pages I went. Of the two companies contacted, Rimvy at Vanguard was first to respond. He showed-up the next day at the appointed time, quoted me a price, which was slightly lower, but in the neighbourhood of my own (amateur) estimate for labour, materials, and clean-up, and indicated he could start the job right then and there. Fortunately (for us), he had arrived in a van topped with ladders and filled with cases of professional-quality caulking (the kind you can't get at Home Depot) in various colours. I colour-matched as he cut away the existing exterior caulking on all four edges of the big window. Lo and behold, there was no insulation behind the caulking! None at all. On a house we bought as "new!" Rimvy insulated and properly caulked the four front windows in less than two hours. We hired him to insulate and caulk around all other windows and doors, which he did at mutually-convenient times. Rimvy's as much artist as "repairman." He communicates well, knows his craft, gets right to work, cares about the resulting functionality and look, and even whistles while he works. I trust him as I trust the quality of the remedy he provided.
