We recently moved into a 140-year-old home, and have been working our way through cleaning the place up to make sure it lasts another 140y. After talking to a few masons, we hired Andrew's Restoration to come out and help sort out the chimneys.
As part of the quoting, I had a great chat with Andrew. I sent him a series of photos, and we went through options and costs. He was clear, reasonably priced, and didn't try to obfuscate what was needed or up-sell anything unnecessary.
We had them out to rebuild the main chimney, which services two wood burning fireplaces. It was covered in stucco at some point a few decades ago, and the bricks & mortar above the roofline had completely rotted away. They took that down, built it back up from new brick. They did a great job matching the old, didn't mind our toddler constantly wanting to look in on their progress, and were friendly and polite throughout.
We had also discovered a decommissioned floating chimney, starting in our 2nd floor bathroom and ending in the attic, with no support walls under it on the first floor. They took a look, quoted a reasonable number to take it down, and worked with us to come out and remove it during a 1-week window between our removing old insulation and adding new to the attic. It was a messy and cramped job, but they got it out and hauled away ~1000 pounds of bricks that had been floating in our ceiling.
Both jobs were well executed, in a timely manner. I'll certainly be using them again if any additional masonry work is needed.
