Gave us great suggestions on window replacements. We love the picture windows and other suggestions he made. He is very knowledgeable and came to our house during the installation to make sure all was going well and we were happy with the windows and installation.

The installers were very skilled and knowledgeable. In my Family Room, the installer even took it upon himself to level the wood shelf under the window he was installing so the wood framing the window would be even and “look nice“ as he said. He didn’t have to put in that extra effort, but he did…he took great pride in his work.

Next Door & Window worked within my schedule and timelines. They are very professional. And Scott the salesperson inspected the installers work to make sure they were doing what they were supposed to. I have nothing bad to say about them.

Very professional, I enjoyed visiting the showroom and being showed around the shop to see how they prepare the windows for installation, and of course meeting those who run the show!

Justin Bartley

Founder & President

I started working in the home improvement industry when I was 9 years old and have spent the last 30+ years constantly learning how to deliver a better customer experience. Home Improvement has always been my passion. I have OCD Obsessive Compulsive Disorder, which means I feel the need to check things repeatedly and perform rituals over and over. Through the years our company has taken on this culture of obsessing over the details for our customers to always strive to provide the best experience possible.

When I am not in the office, you will find me at the local theatre watching my daughter perform in musicals, traveling around with my son’s hockey team, and going on a long bike ride with my wife through the beautiful Chicago area.

Matt Slowiak

Procurement/IT Manager

I’ve been in the Window & Door industry for over 25+ years. I’ve labored on job sites, loaded/unloaded trucks, sales, purchasing, just to name a few things. I just recently had my 10 year anniversary with Next Door & Window as the Procurement & IT Manager. I truly enjoy innovating new systems and procedures at our office. Always trying to improve upon things we currently do, I am never satisfied.

When I’m not at the office you generally can find me at a table somewhere playing/teaching a strategic board or card game. Often I’m trying to convince my co-workers that we have enough time to play one during our lunch break

I love spending time with wife and daughter. It’s no secret we enjoy visiting Walt Disney World in Florida & my family in Denver

Jason Alice

General Manager & Integrator

My current role at Next Door & Window is General Manager & Integrator. I have been with Next Door & Window since 2015 and in the construction industry for most of my professional career. I oversee day to day operations at NEXT Door and Window across all departments. Away from work I am a loving husband and father of 3 boys. When I am not spending time with my family or working, I am an avid golfer and can usually be found on the course.
