As you walk past a window in your office, you feel a slight draft. That tiny bit of air can’t be doing that much harm though, can it? Unfortunately, yes it can. Improperly sealed windows account for up to a 20% increase in heating and cooling bills! This can add up to hundreds or even thousands of dollars for a large, commercial property. Aurum helps make your business more cost-effective and environmentally friendly with our professional Saskatoon window caulking services.
