Long Island window and patio door replacement
Infinity Replacement sells and custom-builds windows and patio doors to fit your home, with expert guidance and a dedicated customer success manager handling every detail.
Assess current windows and doors
Your consultant will evaluate your current windows for moisture issues, water damage, rot, or structural concerns. They'll also note any energy efficiency or functional issues.
Select installation method
Depending on the condition of your existing windows, they will determine if it's a redesign with a full-frame replacement or one-for-one insert replacement.
Select the right options
From window style to performance glass to hardware finishes, your consultant will walk you through all the design options.
Understand replacement costs
Your consultant will help you price out your replacement and understand how to budget for your project.
Take measurements
Your project manger will visit your home to measure openings, accounting for variances. These measurements will be used to place your order and custom-build your new windows and doors for a proper fit.
Plan an installation timeline
When placing your order, your consultant will give you a detailed timing estimate. We will be in touch with you over the weeks your order is being custom built, keeping you posted on progress and confirming installation dates.
