Testimonials From Satisfied Customers

"These guys are great. I made an online appointment for an estimate and they were at my house the next week. They were only there for an estimate but the price, (I had gotten two other estimates for double to install the same damper/caps), could not be beat. They did the work on the spot, were extremely clean and neat and very polite. HIGHLY RECOMMENDED."

People with Thumbs Up for XL Service LLC"XL Service LLC has been wonderful! After our new home purchase I was searching out someone to do our chimney inspection and sweep. I choose them because they responded quickly, were professional, had better pricing and truly seemed to care about providing great service. The tech that came to do the work was very nice and did a great job. We were happy to know that we could actually have a fire in our fireplace and he reassured us of that! We needed some other work done and they have gone above and beyond to provide us great service! I will be using them from now on and would definitely refer them to anyone! You are in good hands with XL!"
