"So Nir and Alexander just left my property. They installed two new Chimney Chases. My entire experience with Chimney Sweep Clean has been absolutely marvelous. Initially when I found Nir on a recommendation by a friend, he answered politely and was at my property the next day. A fair estimate was given and I had to wait two weeks for the custom made chases. Remarkably the Chases were made in only a week, he called me and was there the next day and they were installed. Amazing!!! The cleanliness and professionalism with which Nir runs his business is really remarkable. The new custom made chases look great. As well during the installation process he took pictures step by step so he could explain it to me. You just don't find companies who operate like this much anymore. I would wholeheartedly recommend Nir and Alexander from Chimney Sweep Clean for any chimney problem you may have. If I could give them 10 stars I would!!"

"Tony and his colleague showed up and got straight to work. The men were careful about tracking any dirt into the house and used shoe covers. The job took about 30 minutes to complete and Tony was a wealth of information on how to use the wood burning fireplace and gave suggestions on using starter wood . They inspected the fireplace and advised I needed two tiles to be replaced and gave me an estimate; along with the $150 credit from the Angie's List purchase the estimate was less than the purchase price for one tile from Home Depot.
I was happy with the overall service and would use them again.

"The service rep was very safety conscious and went over safety details on how to properly build a fire, how to dispose of the embers, how to avoid extra smoke coming into the house. he did a thorough examination of the chimney flues, inside and outside and checked some brick facing in the attic that a previous inspector had explained needed to be re-mortared. He had a thorough knowledge of the construction of our chimney and pronounced in in very good condition. He also confirmed the proper discharge location for fallen embers into the basement, which had been a worry for us. He pronounced that in good shape as well. He also went over the idea we wanted to explore of making the fireplace into a two sided one and he explained that this was indeed possible. but he recommended that we use the third flu, which he discovered and which no one had told us about, and explained we could convert that flu to a gas fired fireplace flu for the room on the other side.
He cleaned up well after himself and was professional throughout. I will use him again every year.

"When I called Classic to make an appointment, Lance was efficient and friendly. I was always called to confirm the appointments the day before. Tommy and his co-worker arrived on time both visits. After the chimney inspection, Tommy outlined the repairs that needed to be done to make my fireplace usable. He recommended vent-free gas logs rather than burning wood as it would be a safer method to use with this fireplace. He also suggested where to look for the gas logs to get the best price and who to call for installation. He was friendly but very professional. On his second visit, Tommy and co-worker arrived a little early and were already working when I arrived at the house. He installed the damper in a very short period of time. The estimate I was given for the damper work was exactly as stated - no hidden charges. Excellent service and excellent job. I will definitely recommend Classic to my friends!"

"It went very well. They came on time. They did their work well. They told me how often I should get it cleaned and if I'm just using the fireplace twice a year, not to worry, that I didn't have to get it cleaned until every 3 or 4 years."
Start with a professional inspection. If damage is limited to a few bricks or the crown, a targeted repair helps keep costs and disruption to a minimum. Severe leaning, widespread mortar failure, or major fire damage usually signals it’s time for a complete teardown and rebuild. Your contractor will outline both price tags, but remember that rebuilding a failing stack is often cheaper than repeated patch jobs and the water leaks or fire hazards they allow.
Cracks provide water with an easy path into the masonry, weakening the bricks and mortar and increasing the risk of collapse or fire. Gaps can also let hot gases and sparks escape into attic spaces. Call a chimney pro as soon as you see cracking so they can seal small joints or recommend a larger rebuild before minor damage turns into a costly emergency.
Smoke rolling back into the room often indicates a blocked flue, a broken damper, or a drafting issue. Have a sweep inspect the damper, flue liner, and any obstructions right away. Most fixes involve clearing debris, repairing the liner, or adjusting the damper so the fireplace pulls air correctly. Don’t light another fire until a professional pinpoints the cause and confirms your system is venting safely.
Most policies cover chimney repairs caused by a sudden, covered event, such as lightning, a fallen tree, or a house fire. They won’t cover damage that stems from neglected maintenance or everyday wear. Review your policy or contact your agent before scheduling work to determine what documentation your insurer requires and what costs you will be responsible for.
Component life spans vary. Clay tile or cast-in-place liners last close to 50 years, while stainless-steel liners last 15 to 20 years. Mortar requires attention every 25 to 30 years, while crowns last 50 to 75 years. Use these numbers as a maintenance roadmap: schedule regular inspections, budget for future upgrades, and replace parts before age-related cracks develop into more significant problems.
