I purchased half a dozen windows from Lifetime twice this year and they did a professional job in all aspects. The no pressure sales consultant, Dan Wells, measure technician, Mike Vohlken, who was helpful with trim details, the project manager John Boswell who reviewed the tilt in operation to the excellent installers, Jairo and Pavil were all very good experiences. I would recommend Lifetime to anyone looking for replacement windows.
