Foundation Crack Repair in Reading, PA
A crack in a foundation wall is the most common reason Reading homeowners call us, and it's the one that's easiest to misjudge. Some cracks are cosmetic; others are the first sign that soil or water pressure is moving the wall. The difference matters, because sealing a crack that's still under pressure just buys a few months before it opens back up.
Reading and the rest of Berks County sit on clay-heavy soil that swells when it's wet and shrinks when it dries. That constant push and pull works on a foundation, and our freeze-thaw winters widen any gap that water has already found. On the city's older stone and block foundations, the same pressure shows up as deteriorating mortar joints and stair-step cracking.
We start by figuring out what kind of crack you have and what's driving it, then match the repair to the cause. That way the fix holds instead of coming back the next wet spring.
Signs You May Need Foundation Crack Repair
- A vertical or diagonal crack that has widened or lengthened since you first noticed it
- Stair-step cracking through the mortar joints of a block or stone wall
- A horizontal crack running across the wall, which points to outside soil pressure
- Water, dampness, or efflorescence (white mineral residue) tracking in along a crack
- A crack wider than about a quarter inch, or one you can fit a coin into
How We Repair It
Polyurethane and epoxy crack injection
For non-structural cracks in poured concrete, we inject the crack full so it's sealed against water from front to back. Polyurethane stays flexible for cracks that still move slightly; epoxy is used where the crack needs to be welded back to full strength.
Carbon fiber reinforcement
Where a crack is a sign the wall is starting to flex, we bond carbon fiber across it to hold the wall and stop the crack from reopening under pressure.
Masonry and mortar repair
On older stone and block foundations common in Reading, we repoint and rebuild failed mortar joints so the wall sheds water and carries load the way it was built to.
What to Expect When You Reach Out
It starts with a few details through the form so we know what you're seeing: the cracks, the water, the sticking doors, whatever made you call. We come out and inspect the foundation inside and out, look at the basement or crawl space, and check how the soil and water are moving around the house. Then you get a written assessment that explains what is actually causing the problem and the repair that fits it, whether that's sealing and reinforcing a crack, bracing a bowing wall with carbon fiber or anchors, driving piers under a settling section, or waterproofing a wet basement. On repair day the crew protects the work area, does the repair, and cleans up before leaving. You get a clear explanation of the work and the number in writing up front, so there are no surprises.
Foundation Crack Repair Questions, Answered
How do I know if my foundation needs repair?
The common warning signs are cracks in foundation or basement walls, especially stair-step cracks in block or a horizontal crack across a wall, doors and windows that suddenly stick or won't latch, floors that slope or feel bouncy, gaps where walls meet ceilings, and a basement that takes on water or stays damp. One small crack isn't always urgent, but several of these together usually means the foundation is moving. The only way to know for sure is an inspection, which is why we look before we recommend anything.Are foundation cracks serious, or are some normal?
Some are normal and some aren't. Thin vertical hairline cracks from concrete curing are usually cosmetic. The ones to take seriously are horizontal cracks, stair-step cracks through block joints, cracks wider than about a quarter inch, and any crack that is actively leaking water or growing. Those point to soil or water pressure moving the wall. We tell you straight which kind you have rather than alarming you over a harmless one.What causes foundation problems in Reading and Berks County?
Mostly the soil and water. A lot of the area sits on clay-heavy soil that swells when wet and shrinks when dry, which pushes and pulls on the foundation. Clay also drains slowly, so water builds up against basement walls and presses inward. Our freeze-thaw winters widen existing cracks, and many Reading homes are old enough that their stone, brick, or block foundations have weakened with age. A repair lasts when it addresses that cause, not just the crack you can see.Do you offer free inspections, and what happens during one?
Yes, the on-site inspection is free. We look at the foundation inside and out, check the basement or crawl space, and look at how water and soil are moving around the house. Then you get a written assessment that explains what's causing the problem and the repair that fits it. There's no obligation to book the work.Are sinkholes a risk for foundations in Berks County?
In some areas, yes. Parts of Berks County sit on limestone bedrock, and ground over carbonate rock can develop sinkholes and slow subsidence as the rock dissolves underground, something Pennsylvania's geological survey has mapped across the region. It doesn't affect every property, but where the signs are there, it changes the repair, because the fix has to account for what the ground underneath is doing. That's part of what we check during an inspection.
