Do not use this company if you have anything more ...

Do not use this company if you have anything more complicated then a simple frame jump. They left gouges in the wall, foam stuck to the drywall, and didn't even complete the work they said they would do in terms of trim out, etc.

Its a shame, because they have a really good quality window at a good price, but do not know anything beyond the bare minimum necessary to put them in your house. Their installers are courteous and know the window portion cold, but you better plan to have someone clean up after them.

Additionally, you will never hear them admit anything is their fault. No matter what, someone else is to blame, and don't expect them to apologize.

In our case, we went with them as they did the other windows in our house for a previous owner, and we wanted them to match. However, their customer service is bad, and I would strongly recommend going with either Glass Rite or Don's over Window World.
