Masonry waterproofing in Throop, PA
Lackawanna County · ZIP 18512 · Published pricing · Call (570) 909-2820
Throop grew up around the Marvine and Pancoast collieries, and the Pancoast mine disaster of 1911 is still the event the borough is remembered for. The ground under the older streets was worked hard, and the culm banks on the Scranton line are a reminder of how much was taken out from underneath. Anthracite Masonry Waterproofing ranks Throop seventh on our list because that history shows up in foundations: stone walls that have shifted a little, slabs that have dropped at one corner, and joints that opened when the ground moved rather than when the mortar failed.
That distinction matters for the price. A wall that has only lost its mortar gets the interior repoint, parge and coating package at $3,000 to $8,000. A wall that has moved gets crack monitors first and a conversation about the Pennsylvania DEP mine subsidence insurance program, which covers that damage and homeowner policies do not. We would rather spend a visit measuring than sell a coating that will crack again in a year.
The river streets have the same groundwater basements as Olyphant and Dickson City on either side of them, and the same answer: drain tile and a sump with a battery backup at $4,500 to $12,000. Up on Sanderson Street and the hillside the work is mostly repointing and sealing the weather walls.
Cracks that open in spring and close in fall
Throop houses near the old workings sometimes have a foundation crack that opens every spring and closes every fall. That is ground moving with the water table, not a wall failing, and the fix is flexible polyurethane in the crack plus a monitor, not rigid mortar that will break again.

Throop homeowner questions
- How do I know if my basement crack is from mine subsidence?
- Fresh stair-step cracks, a corner of the slab that has dropped, doors that started binding, or a crack that changes width by season. We put monitors on it for four to six weeks and tell you straight. Subsidence damage is filed with the state program, not repaired first.
- What does stone foundation waterproofing cost in Throop?
- $3,000 to $8,000 for interior rake, repoint, parge and coating on a typical Throop house. River streets with groundwater at the slab add drain tile at $4,500 to $12,000.
- Is mine subsidence insurance worth buying in Throop?
- Yes. The state program is inexpensive, homeowner policies exclude ground movement, and Throop is in the middle of the anthracite field. We are not an insurance agent, but we say this to every Throop customer.
- Can a shifted stone wall be repaired without rebuilding?
- Usually. Stones that have moved a little get reset, joints repointed in lime mortar, and the wall coated. A wall bowed more than an inch or two gets an engineer involved before we touch it.
