Excellent service:
Our installer, Zack, called to inform us of his imminent arrival and arrived on time. He worked diligently without taking any breaks. Installation was flawless. He cleaned up afterwards and answered all questions and concerns.

I recently had an exceptional experience with the installation of my new sliding doors by Next Door and Window. The project was extensive, requiring partial removal of my home’s front façade, yet the team handled it with remarkable professionalism and precision. Their attention to detail, craftsmanship, and commitment to quality were outstanding. I am thoroughly impressed with their work and highly recommend Next Door and Window to anyone seeking superior service and results.

This was a Fantastic experience from beginning to end.
They kept in touch with me constantly, and every worker who came to my home was friendly & courteous. Very efficient.
They replace two 27yr old french doors going out to my backyard patio with a beautiful sliding glass door.
We couldn't be happier.

We got our Costco Marvin windows through Next Door and Window. They helped take our NINE double-hung windows to these beautiful full wall sliders. From the sale, project progress, scheduling, and install have all been amazing! Clear communication was had with confidence for the team. They were clean and protected our space while working. The end product is STUNNING!

I had a great experience with Next Door Windows and Doors! From start to finish, the service was professional and smooth. The team kept me informed throughout the entire process, and the installation of my new patio doors was done with great care and attention to detail. The installer was very professional, efficient, and left everything spotless — I didn’t have to clean up a thing! I truly appreciate the quality of both the product and the service. Highly recommend!

From initially stepping into Next Window showroom until after our Infinity replacement window install, our experience was amazing! Everything went so smoothly starting with our knowledgeable and helpful salesperson who had exceptional communication. During the entire process any question we had was immediately answered. The install crew was neat, friendly and helpful. The outcome resulted in a quality window with now an updated modern visual appearance. Can’t beat the extended 10 year labor warranty that Next offered as well. We are enjoying our home’s new look!
