Lifetime Windows was an excellent company to work with. From beginning to end, they were professional, fast, communicative, and went above and beyond with our window installation. I'm so glad I used them for our project. I would highly recommend them!

I used Lifetime to repair my house after the hail storm. My old solar company went out of business so I contacted Lifetime on a referral from a neighbor. They replaced the roof with a free upgrade to impact resistant shingles, replaced 5 broken solar panels and fixed a few windows. They also found a handyman to rebuild my mailbox that was destroyed. All pretty quick and easy.
