We didn't know what was wrong with our chimney, but could see moisture was damaging the plaster in the ceiling around it. We consulted a roofer who said the issue was the flashing (on the roof just above the room where damage was visible). New flashing had absolutely no effect. Talked to another roofer who admitted he was stumped and recommended a company called "Chimney Scientists". Best recommendation EVER. The Chimney Scientist inspector recognized the problem immediately: unfortunate repairs in the 1980s to this chimney built in 1900 used a modern type of mortar (Portand cement) that trapped moisture inside our chimney, forcing water out through brick (and then into surrounding ceiling plaster). This past week Chimney Scientists rebuilt our chimney in the top floor of our house and up through the roof using historic lime-based mortar. They found reclaimed brick that closely matches our original brick for the exposed chimney inside the house. Above the roof, they used new brick that will resist the elements for a long, long time. End result: a gorgeous, healthy chimney inside and out. During the job, they provided thorough protection around their work area. At the end of the job, they cleaned up to perfection. All along the way, they cheerfully provided crystal clear and detailed explanations. Maybe best of all: they LISTEN. Whenever we had any concerns or questions, we were heard and any needed adjustments were made right away. The name Chimney Scientists isn't just great branding: these guys really DO understand the science behind chimneys and they take great pride in skillfully solving chimney problems. 10 stars out of 5.
