Chimney Dampers Function

A thin stainless steel breaded cable drops down your flue liner and attaches to a handle, which we mount to the side wall of the firebox by drilling 2# – 1/4″ holes into the firebrick, next  fastening the handle bracket with concrete anchor bolts. When we install the handle it is positioned in a easy to operate area in the firebox. As to pull the chain in a downward motion the damper closes and Vice versa, as the damper open and closes you will hear a suction sound that ensures you have a tight seal.

Chimney Caps: Essential Protection and Aesthetic Enhancement

Chimney caps are crucial components that protect chimneys from weather damage, debris, and animal intrusion. They come in various materials like stainless steel, copper, and galvanized steel, each with unique attributes such as durability, corrosion resistance, and visual appeal.

Proper installation is key to ensuring optimal performance. Caps can be single or multi-flue, top-mounted, or custom-designed for specific needs. Features like spark arrestors and animal guards provide added safety and protection.

While chimney caps offer numerous benefits, misconceptions persist about their fit, water-blocking abilities, and problem-solving capabilities. Ongoing debates explore the necessity of custom caps, environmental impacts of materials, cost-benefit analysis, and the role of caps in home energy efficiency.

Client Testimonials

“Highly recommend Guardian Chimney Solutions - I called them on a Monday afternoon concerning a smell coming from my fireplace and they were here by Tuesday. As a new home owner, were knowledgeable and wonderful to deal with. They took the time to explain everything. Definitely will be using them if there are any other issues!.”

Cassie Letson


“Had raccoons in my chimney earlier this week (cute pictures attached!) and realized it was time to do something to keep them (and the bats we've previously had in our chimney) out! I called around for different estimates and checked all kinds of reviews online. Not only were Guardian's reviews the best out there but the estimate I received matched the best out of a number of other local companies. I called on Tuesday and they were out on Wednesday getting the job done. I was very impressed with the service and would happily recommend them to anyone and everyone! Thanks, and keep up the great work, Guardian Chimney Solutions!"



“Very responsive, timely, efficient, and expertly done. Worked hard and quietly the entire time they were on site. Finished ahead of schedule. Respectful and pleasant. If we have another chimney issue, these guys will be my only call.”

Rich Harman


“We had our long-neglected chimney repaired from the roof line up to the top of the chimney. Guardian ground out the mortar around the entire chimney and rebuilt the top number of rows of brick with new brick and put a new cap on the top to replace the badly cracked cement cap that was there. The tuck-pointing that they performed on the chimney and another area above a door all looked well done. They completed the job in one day, in spite of a short downpour that halted their work. They cleaned up all evidence of their work afterwards and left our yard looking like they never were there. Joe, the owner, was a pleasure to work with. He did most of the brickwork himself and repaired a part of the chimney that was unexpectedly in bad condition without charge. He was clear in his communication with us in a written proposal and priced the job more reasonably than others. When rain was predicted on the original date of work he called and let us know he had to reschedule and rescheduled for the next day, showing up on time. He was trustworthy and very easy to work with. We would certainly recommend him to others for their chimney and brick work.”



“Showed up on time for both estimating and doing the work. Estimate was very clear and thorough. (And less expensive than the "other guy".) Work was done in a timely manner, everyone was polite, and they cleaned up afterwards. Every company should be this good. Kudos!.”

Michael Byrne


“Couldn’t recommend Joe and Guardian Chimney Solutions more if you need any repairs done to your chimney. Joe took time out of his already busy day to fit me in and repair damages on my chimney so that I was up to code before closing on my house. He was timely, personable, and best of all very skilled at what he does. All in all a great experience.”



“We were extremely pleased with our experience with Guardian Chimney Solutions. We had a fireplace liner installed last year and had it cleaned for the first time this summer. Both Joe and Derek were professional, friendly and and prompt. They answered all questions thoroughly and were easy to work with. We would highly recommend this company."
