Your new windows or doors installation experience with Lifetime Windows & Doors begins with our top-notch installation team. Each team is led by our own Lifetime Certified Installer. When we arrive at your home, we’ll begin with a walk-through with you to explain what we will be doing and to determine if there are any special care instructions or concerns about your property and belongings.

Lead Safety

During window and siding installation, your home will be visited by one of our inspectors. Every inspector is trained and certified with the EPA. Their job is to inspect the quality of the installation by our siding and window contractor, the safety of the job site and to ensure your property is treated with respect. This also ensures that Lifetime Windows and Siding always complies with the EPA's new regulations for the handling of Lead paint. Each Lifetime Windows and Siding installer has EPA training and is certified to handle lead paint installation on houses built before 1978.

Quality Inspection

When installation is complete, Lifetime Windows & Doors will take the customer on a final walk-through to assure they are completely satisfied. The job site is thoroughly cleaned and before we leave, and our crew will clean your windows.

Be Assured that We Stand by Our Work 100%

Lifetime Windows & Doors come with a no worry “Lifetime Plus” warranty. Everything about your new windows — the frame, the sash, the seals, the screens, even the glass — is guaranteed to meet your highest expectations. And the warranty is transferable to the next homeowner if you decide to sell!
