I advocate to all that if you are doing upgrades to your home this year use small businesses. It is the small businesses that helped pull the US out of the recession way back when, and it will be the small businesses that America will come to rely on.
Big stores are like Oil Companies they are more interested in profit then the consumer. I purchased new windows by Home Depot last summer. $12K for 17 windows. I was charged $700. for windows that were 27" x 72" being told that I had "odd" size windows and that's why they cost so much.
The installation day came. The installer advised me as they were striving to install the windows in my brick home that the windows were defective. Indeed the miters on the "double hung, special windows, hand made just for my home" were up to 4mm and wider apart. I have "plastic (Home Depot's exact words)" sticking out perpendicular to my windows. I bought vinyl windows not plastic.
I have a window in my kitchen hung crooked. We can see where water leaks have gotten past the sealing job they did. My sister noted she could feel air coming in through various sealed windows.
I wrote to Home Depot and they said "nothing was wrong with the windows." Funny as not one person from Home Depot ever came back to check on my windows.
To make a long store short, bigger stores such as Home Depot, would rather have you think it is "you" versus anything wrong with their product. Look at HD just find yourself a smaller company that is bonded and has been in biz long enough to stand behind their product for the next many years to come. Your business might just save another small business. And, you should get better service.
