When we say this is the last window or patio door you’ll ever have to buy, we mean it. In fact, every properly installed Milgard product is guaranteed against defects in materials and workmanship for as long as you own and live in your home. How can they offer this kind of guarantee? Because they set very high production standards and they work hard to live up to them to greatly reduce call-backs. However, in the unlikely event you do need a repair; we’ll perform it – including materials and labor. No hassles and no hidden exceptions.
