“We had a great experience from start to finish with our window installation to replace drafty wooden windows. The windows were high quality. The team was easy to work with. The install went perfectly leaving us with beautiful windows.”
Kelleigh
"Lakeside came and replaced our screens on our screened in porch with windows as well as doors. They were extremely responsive throughout the whole project. Their crew came out every day on time, super friendly and really transformed that entire space. I couldn’t be more pleased and will use them for future projects."
Jennie K.
"Used Lakeside for new windows for our entire house. Communication was excellent and the installers showed up on time or even early on each day. Everyone from sales to installers to follow up were awesome. I wouldn’t hesitate to call them first for any future project that we may have."
