Window World of New Hampshire has gone above and beyond. I was an installer for years. I'm a Wartime Veteran of Desert Storm. I was blown into a concrete wall while serving. Since my back was in such horrible shape, Harmel Sabourin the owner offered me a position in sales instead of installations. It was such a wonderful gift to be able to provide for my family without being in pain at the end of everyday. It's great working with such a professional group of people that actually care about the homeowners, unlike other companies I've worked for! Thank you Harmel and Window World. It's a great feeling having homeowners thank me for such great finished products like Entry Doors, Siding and Windows.
