John Greulich
I would highly recommend this company!
I had two sliding patio doors installed recently. The installers were professional and hard-working. They laid down runners in my home to keep it clean. The doors operate with great ease and are so attractive! They did an amazing job with the trim around each door both on the inside and outside.
They were very neat while they were working and cleaned up and took all of the debris with them. I would highly recommend this company!
A Miller
Extremely happy with the results!
Extremely happy with the results! I had them install a basement door because mine was original in a 1920s house and it was a hot mess. Couldn’t even get it open and now I have a beautiful door. The sales rep was very friendly, as well as the installers. Everything was done in a timely manner, and they left it looking cleaned up and beautiful. 10 out of 10 will use again.
Heather Hays

Lauren Shade
These guys are amazing and friendly
These guys are amazing and friendly as heck, thank you so much for your hard work. Brian came out two separate times to quote several windows for me and was incredibly kind. Elijah, Kelly, and another gentleman whose name I didn’t catch came out to do the work today and they did a beautiful job. Everything is installed perfectly and they left it nice and tidy when they were done. I’ll definitely be requesting their expertise again in the future. :)
Emily
So pleased with B.E.E. and Brian
I was so pleased with B.E.E. and the service that Brian Middlesworth provided. The scope of the work was well over my knowledge of window repair. We discussed a consultation, and he arrived on time for it. Originally, the plan was to have the work done after the consultation, but Brian was a wizard and got my two windows back into working order in what felt like no time at all, having the materials and expertise to complete the job right then and there. I am so happy that I used their services, and I highly recommend them for your next project. I know I will when the time comes. Thanks and keep up the great work, Brian!
Ken Stoecker
They Have Our Highest Recommendation
We chose to do business with Building Envelope Experts after receiving a wonderful recommendation from a good friend. We now share their enthusiasm and would be delighted to recommend this company to friends and neighbors!
This is a family-owned company and our initial meeting with Brian Middlesworth answered all of our questions and gave us the confidence to move forward. Elijah and Clayton came to install the new glass block windows in our walk-out basement and did a terrific job living up to the name of the company! They were friendly, respectful, neat, and efficient. The finishing work is excellent. We are so happy with the final result! We would be happy to use Building Envelope Experts on any future projects that may arise. They have our highest recommendation!
Barbara Berner
Everything turned out fantastic
We had a great experience with Building Envelope Experts today. They replaced both a glass cube window and a double pane window for us, and everything turned out fantastic. Elijah and Kelley were professional, efficient, and clearly take pride in their work. The installation looks great, and they made sure to clean up everything before they left—which we really appreciated. I would absolutely recommend working with them!
Rebecca Hopkins
Premium customer service and work product
In an era where it seems like a lot of businesses are running their employees ragged, with quick visits and cheap materials, optimizing margins, you forget what good, thoughtful customer service along with a good work product can be like.
Grant spent hours evaluating my home and explaining the plan in detail. I was on a budget, so he broke my plan down into sub-projects in order of priority. The interaction felt like a consultancy and not a sales pitch, providing useful information, without constant follow-ups to close some sort of deal. In other words, it felt like I was interacting with a professional, confident business.
He was actually present throughout the project, checking in with his team and myself. Ironically, this wasn't necessary with his team. Elijah, Tim, and Clayton were equally professional. Everyone actually cared about the quality of their work. They were actually normal, kind people who actually cared about the quality of their work, while remaining intentionally mindful and respectful of being in someone's home.
The work performed was air sealing and insulation. The team had diagnostic tests, including blower assessments and thermal imaging, with before and after comparisons for a data-driven/supported approach. They actually cleaned up after themselves so well I think my house might have been left cleaner than how they found it.
You might have noticed I said "actually" a lot. That's because with this old house I've had a lot of local well-known companies taking on projects, and those experiences have caused me to expect less.
Building Envelope Experts offers a premium customer service experience and work product at normal, competitive pricing.
This is not some paid, or worse, AI review. If you have issues, call them up and give them a chance to earn your confidence. You're only risking some of your time.
Doug Hammerstroem
They Did an Excellent Job!
The team came out to spray foam our basement and they did an excellent job! They're very courteous, prompt, reasonably priced, and did a great job with cleanup afterwards. Highly recommend!
Phillip Heslin
Very professional team
Glass block windows for bathroom. Very professional team. Worked hard. Knowledgeable. Helpful. Confident having them in our home.
kimberly shelton
Highly recommend to others
We hired Building Envelope Experts to install two basement glass block windows. I was struggling to find the right professionals to help and luckily was referred here. Highly recommend to others, the entire experience was great and the pricing was very reasonable. Thanks again for the help!
Joe Watts
Very happy with the patio and front door
Very happy with the patio and front door. Kelly did an amazing job. Would definitely recommend them and will call if I need anything else. My new front door was exactly how I had pictured it. In
Grace Schupp
Did a Beautiful Job with Our Windows
Elijah and his team did a great job replacing our windows. They were very professional, courteous, and did a beautiful job with our windows. I would definitely recommend this team and will keep them in mind for future work.
Jill Dierker
Very professional and thorough
Grant and his whole team were very professional and thorough with my attic insulation and air sealing job. Grant sat down with me for 2 hours to discuss everything about insulation, air sealing, HVAC, and really create a whole game plan for the home. We discussed multiple options and price points. The work was a lot less disruptive than I had expected. It is a multi-day job, but the crew cleaned up after themselves every day. Really looking forward to talking with Grant one day in the future when I need a new HVAC system.
Adam Treaster
I definitely made the right choice
I hired Building Envelope Experts to install a new ProVia exterior door, door frame, and threshold for my basement.
I was thoroughly pleased with the quality of the installers’ work, as well as their professionalism. They showed up a little early, and actually finished a lot earlier than I expected. They also cleaned up after they were done.
The new door, door frame, and threshold look great. The price was great, too, given that I wasn’t looking to spend a lot of money for just a basement door.
I did quite a bit of homework online, evaluating various companies and their customer reviews, before selecting Building Envelope Experts.
Based on my personal experience with Building Envelope Experts, I definitely made the right choice. I highly recommend them for anyone who needs an affordable door replacement.
David Burnett
Very Professional Team
I have used this company twice over the years. First to add custom storm windows for my historic home and again after the tornado to replace storm windows that were damaged (the storm windows saved the historic windows from breaking). Very professional team.

Mohammad wazin
LOVE the new windows!!
One of the top 3-4 experiences that I have had with a contractor over the past 20+ years. Everything went exactly how Brian said it would, and the gentlemen that did the work were some of the most professional that I’ve seen. LOVE the new windows!! Thanks, Building Envelope Experts!
Steve Hinkebein
This company is by far the best!!!
We just had Building Envelope Experts put in a large bay and 3 casements in our LR and DR. Fantastic! The windows are beautiful. Changes the whole look of the room. The installers are real craftsmen, going the extra mile that a 107 yr old home required to get the fit perfect. And they made the install as convenient as possible. Easy peasy. We also love the 3 glass block windows in the basement and 2 new doors. They put in 3 lovely doors 2 years ago that continue to exceed our expectations. That’s why we didn’t even bother to get quotes from any other company. I’ve done multiple rehabs and this company is by far the best!!!

The difference in home comfort was noticeable
We had a new roof installed only to find out afterward that our attic had almost no intake ventilation due to blocked soffits—definitely not ideal. That’s when we contacted Building Envelope Experts, and working with Grant Vogel was a game changer. Grant took the time to thoroughly assess our home, walk us through our options, and customize a plan that addressed everything—from creating real attic airflow to venting bathroom fans properly, adding high-quality insulation, sealing vulnerable areas, and more. The crew was professional, the work was completed on schedule, and the difference in home comfort was noticeable almost immediately. Even better, when a minor issue came up after the work was done, Grant responded right away and made sure it was fixed quickly and completely. If you're serious about improving your home’s energy efficiency and long-term durability, I highly recommend Grant and the team at Building Envelope Experts. They really know their stuff and stand behind their work.
