You know it's been a good vacation when you come home to...having to replace a few windows in my house after we discovered one leaking from the third floor into the basement. I'm wondering - should I buy the windows separately and hire an independent contractor to do the install or simply go to Home Depot or a window contracting company? Anyone in NOVA with a recommendation? Thompson Creek Window Company is coming on Monday morning to give an estimate, but I will get more than one.
