I strongly do not recommend Gem Chimney and Duct (also operating as Gem Services LLC, Air Duct Services, and Pro Home Services) due to poor workmanship, deceptive business practices, and serious safety concerns. I hired them in September 2024 to replace a fallen flue pipe cap and stabilize the pipe, paying $1,354 for work they guaranteed for 10 years. By November 2024, the cap fell off again, and their so-called repair involved securing it with tape and screws. After hiring another professional, I learned they installed the wrong type of cap, creating a hazardous environment by blocking proper ventilation. The inspection confirmed my flue pipe was in good condition, contradicting their claim that their faulty cap was the "only option." They refused a refund, blamed the weather (despite no extreme conditions), and tried to charge an additional $1,200-$1,400 for another fix. Their misrepresentation is alarming--they are listed under multiple business names and lack transparency. I had to pay another company to fix their work, proving their incompetence. I have attached pictures of the cap they installed and their unacceptable "fix" using tape and screws after the cap fell off. Additionally, after I pursued a resolution through Thumbtack's Trust and Safety Team, I noticed that this company is no longer listed on Thumbtack, which raises further red flags. Do not trust this company--avoid at all costs! read more
