We had a salesman coming in our house telling us nice things about Landmark windows, how good the quality of their windows are and how qualified and trained are their installers. Also, how great is their lifetime warranty. Well let me tell you, the installers did a poor job to put the windows in. It is very difficult to get a hold of Landmark and get a repairman to fix the mistakes done during installation. If you like quality work, don't do business with Landmark home solutions and don't beleive anything they say.
