I am very pleased with the service of Northeastern Chimney Sweeps. I have an older bungalow with two chimneys with a river rock face whose mortar had eroded and the chimneys were showing signs of leaking and water damage. First of all, Northeastern was one of the few that would even come out and look at the job - many wouldn't even touch it because it was river rock and not stone or brick. I paid for the inspection which was very thorough and showed the damage with detailed photos (it was pretty bad) and the inspector explained both the damage and the process by which it would be repaired. I scheduled the repair - a few weeks out due to other jobs. I was called a few days prior to confirm the appointment. The guys showed up on time, were very polite and respectful of the property. They set up scaffolding, being very respectful of the gardens beneath them. They worked in extremely brutal conditions (heat and humidity) without a complaint. They cleaned up every day and only asked to use our hose for water. In two days, they were done with the grinding and new mortar application. A few weeks later, they came back to waterproof both chimneys. Again the appointment was confirmed by their office (who was also a pleasure to deal with). They quickly waterproofed both chimneys and were on their way. Fast forward a few weeks to Tropical Storm Henri. A lot of wind and heavy rain. and not one drip or leak from either chimney. I am more than satisfied with their work and would highly recommend them to anyone looking for chimney repair.
