What Our Customers Are Saying

We are extremely happy with the results
After doing some research and looking around, we hired Bossline Spray Foam for our basement air sealing job. The entire experience, while nerve-racking at first, went really smooth.
The quality of their customer service started right away with Cheryl, the office manager and Rob, the Sales Rep, who were incredibly responsive and efficient in setting up the job.
Technician Eli Thompson led the installation and was simply fantastic. He was highly skilled, meticulous, and professional. We were extremely impressed not only with the high quality of the spray foam product and the work itself but also with the level of care he took of our house during the process. The cleanup was spotless, and Eli took the time to answer all our questions and offer excellent advice on maximizing our energy efficiency.
It’s clear this company prioritizes both quality work and customer satisfaction. If you are ever thinking about air sealing your house or really any space, you should definitely consider looking into Bossline Spray Foam as one of your choices. We are extremely happy with the results. Thank you!

Would definitely recommend
“I am very glad I chose Bossline for my spray foam project. They were professional, quick, polite and one of the more important things to me, they were friendly. They did a fantastic spray foam job as well. Almost a shame to cover it up, it looks so nice just bare. In fact, my son suggested we leave it cause he said it looked so cool. I would definitely recommend Bossline if you’re in need of spray foam.”

Workers were top notch
“They did a great job on our house. Highly recommend them for your spray foaming needs. Workers were top notch in doing their jobs to make sure everything was covered up and cleaned up after the job was done.”
Andy

Very pleased
“We are very pleased with our spray foam. Our basement is much more comfortable. Retaining the heat in winter, with little or no summer humidity. Our dehumidifier was out of action all summer.”
John

5 Stars in my books!
“The crew did a very nice job. They were well mannered, polite, and helpful. They also cleaned up really well.
Very good crew you have there. 5 stars in my books!”
Gary

On Time, Well Priced
“We hired Bossline Spray Foam to coat a very tight crawl space.
The result was a much warmer floor this past winter.
The work was done on time, well priced and we would definitely use Bossline again.”
Doug

Recommend!
“They did our job on time and on budget.
A big part of it was weather-dependent, so it was good of them to be flexible with the schedule.
They also were very cautious about over-spray.
Recommend!”
David

They Do An Excellent Job
“I own Thompson Drywall and Custom Finishing and I’ve used Bossline Spray Foam.
Great company to work with they do an excellent job. Very professional company and a great bunch of guys.”
John

Clean And Professional
“Amazing job! Clean and professional!
Had them do the entire crawl space as well as the box ends in the rest of my basement.
Made a BIG difference in the heating costs last winter. Definitely recommend this company!”
Chris

Would Use Them Again
“Rad Home Improvements recently hired Bossline Spray Foam to do a renovation we were doing for our clients. They worked efficiently, were on time and on budget! Would use them again and recommend them to anyone who needs quality work.”
Dale

We Highly Recommend!
“Bossline did the spray insulation under our cottage this past summer. We are thrilled with how much warmer it was in the fall.
But what we love the most is how solid our floors feel.
We hadn’t anticipated how much structural support it would add.
We were also impressed with how clean everything was when they left. We highly recommend!”
Star & Sean

Excellent Communication
“Bossline could not have done a better or more professional job. On time & well priced with excellent communication. They were able to do 100% of the area under our cottage when a well respected competitor said they could maybe cover 70% due to areas of low clearance. They did not miss a square inch and often the insulation was thicker than contracted for.
The result was a warm floor in the winter and a 3 season cottage turned into a 4 season one.”
