Lifetime came as a referral from a family member who used them 40 plus years ago, wow! I have to admit, at first I was a little thrown off by Lifetimes "style". I dealt with 5 different people, but they all knew what was going on. I didn't think they provided a lot of information or explanation with any step of the process but as we got other quotes I knew what to ask. It's not a secretive or dishonest approach, just very to the point and if you don't ask maybe they assume you know. While their pricing was not a detailed itemization on some fancy form just a lump sum number it was $1000-$1300 less than the other quotes for I think a little better product and their choices greater. Their turn around was half the time of the other companies (maybe even quicker). Installers were very friendly and efficient. Both the estimators and installers were very timely with the appointment windows. We did run into one problem that the other companies brought up during their estimates due to the shape of our door frame. The lifetime installer pointed out that there was going to be this same issue (which I brought up that the other companies mentioned this) but then he made adjustments that did not completely eliminate but greatly reduced the issue and we are satisfied. Our doors are quiet and smooth and it looks like a completely different house.
