"Dave was amazing to work with. He walked us through the whole process and explained the best places for a wood stove in terms of heat, and then worked with us to help us find a new wood stove. We got 3 other quotes, and they all tried to get us to buy 3k-6k stoves from them. Dave found us a great $800 stove and then picked it up for us. AND his quote for the installation work was almost half the amount of the other agencies. I cannot recommend him enough. Especially if you are looking for someone that wont try to upsell you and work within your budget."

"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.

"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."

"The worker told me that the inside of the chimney had deteriorated seriously and needed a liner. So that was a significant additional purchase. Used a different company the following year, and that worker told me the liner was not installed properly. It is impossible to say what actually is the case. I do not have enough knowledge to know.

"The process went fine. They arrived on-time and performed the work acceptably. However, they marred some woodwork around the fireplace with the large wand they use to sweep the chimney. The supervisor kept trying to sell me an air duct cleaning the entire time they were here.

"I wanted to construct and extension on my home so I called Arius and the engineers came out and assessed my property and proposed a few different options that meet my needs. They helped me select the optimal design which meet my needs and within my budget. The design and construction was executed flawlessly and remained within our pre negotiated price and schedule. I was very pleased with their work."

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.
