Eastern Waterproofing provides chimney leak repair for the part of the chimney you see from the basement: the cleanout, the chimney block, the hearth, and the lower-level fireplace. We drain the water that collects there into a system below the basement floor, so it leaves the chimney instead of building up inside it.
A company owner, not a salesperson, works with you to design each repair. We have provided waterproofing and drainage services in Connecticut and western Massachusetts since 1976, and every quote comes as a free written proposal with references. Financing is available.
Water can reach a chimney from above or below, and each needs a different fix.
Rain and snow can enter the top of a chimney through a missing flue cap, a cracked crown, gaps in the flashing, or worn mortar joints. For a lower-level fireplace, water dripping into the firebox is often fixed by installing a flue cap.
On lower-level chimneys, the cleanout, block cavities, and hearth commonly fill with groundwater. It is the same groundwater our established waterproofing services in Manchester address elsewhere in the basement, and the fix is the same: give it a drainage path.
Check these areas during heavy rain:
If the dampness and efflorescence extend to the foundation walls around the chimney, our dampness and wall coatings service addresses the walls.
Where the water appears usually points to its source. Use this table to match what you see with its likely source and the usual fix.
| Where the water shows | Likely source | Usual fix |
| Dripping into the firebox | Water entering at the top of the flue | A cap on the flue |
| Cleanout or block cavities | Groundwater in the chimney base | Tap into the inside footing drain, or install inside drains if there is none |
| Hearth surface or edges | Water leaking into the hearth | Remove the hearth top, drain into the system below, and replace the top |
Chimney drainage is part of our waterproofing and drainage services. The method depends on whether the basement already has a drain system under the floor.
In a basement with an inside footing drain, we tap into the chimney cleanout, the chimney block, or both. The water then drains into the existing system instead of standing in the chimney base.
Where a drain system is in place, we remove the top of the hearth to expose the drain beneath the floor, then replace it. Any water that later leaks into the hearth drains into the system below.
In a basement with no drainage under the floor, we cut out a section of the floor in the problem area and install inside drains. These usually run to a gravity line or a sump system. If water also shows up along the edges of the basement floor, ask about our floor-level seepage repair work at the same time.
Eastern’s standard for a proper inside drainage system:
Because the drain sits below the floor, it lowers the water table under it. If water is showing up at your chimney now, call (860) 875-6646 and describe where and when you see it.

Yes. On lower-level chimneys, the cleanout, chimney block, and hearth commonly fill with groundwater. In the basement, that shows up as wet block, white efflorescence, a damp hearth, or standing water in the cleanout.
It depends on what is already there. If the basement has an inside footing drain, we tap the cleanout and chimney block into it, and we drain a wet hearth by removing and replacing the hearth top. If there is no drain system, we cut out a portion of the floor in the problem area so we can install inside drains.
Not necessarily. New inside drains usually run to either a gravity line or a sump system. When the basement already has an inside footing drain, we connect the chimney cavities to that existing system rather than install a separate one.
Yes. An inside drain system installed for the chimney is expandable, so it can be extended if other seepage problems appear in the basement later.
A track or curb system that sits on top of the floor does not lower the water table under the floor. A drain installed below the floor, next to the footing, does. That is why Eastern installs inside drains below the floor rather than on top of it.
