Long Island Replacement Window Installation Q&A

There’s one fact homeowners on Long Island often overlook when selecting replacement windows: even a superior quality replacement window may fail prematurely if the installation is not completed perfectly. At Renewal by Andersen of Long Island, we strive to provide each customer a start to finish signature service and installation is an integral, and critical part of that process. And, a perfect installation begins with a professional team.

As the president of Renewal by Andersen of Long Island said, “We’re really proud of our installation team. Not only are they expert craftsmen, but they are totally committed to ensuring every one of our customers has a great experience during the installation of their windows and patio doors.”

Below are a few of the most common questions we hear about the installation process, and their answers.

Q. How can I be sure Renewal by Andersen of Long Island installers really know what they are doing?

A. Our installation crews undergo a rigorous training program (the Renewal by Andersen Certified Master Installer Program) before they install replacement windows and patio doors. The program allows technicians to gain valuable experience working alongside expert craftsmen.

Q. Are installation technicians bonded?

A. All crew members are carefully screened, and undergo a comprehensive background check during the Certified Master Installer Program. You can have complete confidence our team is focused on delivering exceptional customer service.

Q. What if something goes wrong during the installation, say glass breaks or a screen gets ripped?

A. Installation errors are rare, but if something goes wrong, we have your back. Our 20/2/10 warranty provides two full years of coverage for parts and labor for issues related to the installation.

Q. Can I hire my own installation contractor?

A. Some brands require homeowners to arrange for installation, much the same way you would hire a contractor to install off-the-shelf fixtures purchased from a big-box home improvement store. Our policy is to streamline the entire replacement window journey, so we only allow Renewal by Andersen certified technicians to install our brand. There is no additional cost for the service or the warranty coverage.

Q. Will I have to purchase building permits before the installation?

A. Each certified installer has a thorough understanding of building codes and regulations on Long Island and the surrounding boroughs. It is our job to apply for any permits and complete the job on installation day in full compliance of local zoning rules.

Q. Can you install replacement windows any time of the year?

A. Yes. We have four distinct seasons here on Long Island, each with its own weather challenges. But, over the years we have found that most extreme weather events don’t last longer than a few days. Since our crews can usually complete a job in just one or two days, we are able to schedule the installation when it is most convenient for you.
