“They exceeded my expectations in the work staff. They built me a doggy door outside of our contract. I was surprised at that, it was above and beyond.”

“Everyone I worked, with did a great job.”

“Lifetime Windows was amazing. From our first visit with Dave to our installation of both the siding and windows, we were exceptionally pleased with using LW&S. We have had nothing but great things to say about the entire team and have referred both our next door neighbors and best friends to using them for their jobs. We had a slight incident regarding some work our basement renovation and Lifetime was quick to repair the damage. Honestly, we will be using them again for any other current or future house needs - we are so impressed.”

“It was a good job.”

“COVID has caused a few delays.”

“It came out even nicer than I thought it was going to look. It exceeded my expectations.”

“The workers that came out here did an awesome job. There were some days it was cold during the winter, and it didn't slow them down at all. This was like November. We were getting really cold weather. They were on time, cleaned up after themselves and were very friendly.”

“The installation crew were professional, very personable, and kept open communication with us throughout the process.”

“Dan on the installation crew was excellent. He asked questions ahead of time to see how I wanted certain things done. He was very professional and extremely talented at his profession, as well as the other members of the crew. I've done a lot of woodworking in my lifetime, and can guarantee that this was installed precise and professional.”

“Absolutely! We have no complaints, from start to finish Lifetime is the best home improvement project we've done.”

“Dave presented the windows well, and showed us some nice options we hadn't thought about beforehand.The installation crew was amazing. Overall project gets 4/5 because we've had a couple service issues since the install.”

“Installation was really well done. Excellent workmanship.”

“All of the installers were great!”

“The project manager and install crew did a great job!”

“Woody, Elena, and Brandon - outstanding!!”

“The installer was exceptional!”

“The window crew was satisfactory. However, the siding installation crew was exceptional, including their PM Rob. They all went above and beyond for us, and were the primary reason we were so patient throughout. In our mind, they took this from a subpar experience to a great one.”

“All of the personnel we interacted with were great. The problem is I do not like the green tint to the windows. From across the street, it looks like we installed green windows. This tint changes the light inside our home also. Some of the rooms' paint color looks gray now instead of beige.”

“I would like to recognize the young lady who came out during installation for exceptional service, she was awesome.”

“They did great.”

“Everybody that came out to work on my house did an amazing job. You can't even tell that it's the same house.”

“the installation crew was awesome!”

“The crew was awesome. They were so friendly, and obviously during the pandemic they wore masks the entire time. They went out of their way to make sure we were comfortable.”

“The install crew was really great”

“The overall quality of the final product. Excellent job! Keep up the great work.”

“I would like to give the exception award to the construction for their awesome service,”

“No no”

“In the end, Lifetime did a good job on our siding. However, from the beginning of the actual job, there were shortfalls in various aspects of the job that last thru the complete job. If anyone has an interest in hearing first hand, I will share, but am not going into detail here.”

“The siding in the end looks good in most places. The color is great. The Hardie materials seem great. The Project Manager Dominick did his best to correct the installers ineptness but still brought back the same team when I told him I didn't want them to finish the job.”

“Installation crew was excellent.”
