Foundation Repair, Basement Waterproofing & French Drain Installation in Pittsburgh, PA

You usually notice it upstairs before you notice it downstairs. A door that will not latch, a gap opening where the trim meets the ceiling, a crack climbing the brick outside. Underneath all of it, one part of the footing has settled lower than the rest and the house is following it down. Ground around Brighton Heights has been cut and filled more than once over the years, so a house can drop at one corner and sit perfectly still at the other.

Foundation repair puts the load back onto ground that will hold it. Steel piers are driven down past the disturbed layer until they reach something solid, then brackets transfer the weight of the footing onto them. Where the drop is small, that is enough to stop it there. Where a house has gone far enough out of level, the piers can bring it part of the way back, and the cracks upstairs close as it comes. Helical piers turn into the ground like a screw; push piers use the weight of the house to drive them.

What piers do not do is dry out a basement. If water moving through the ground is why the footing dropped, the drainage has to be handled as well or the same thing happens again in a few years. That is why the inspection looks at the outside of the house as closely as the inside. We work homes from Greenfield to Squirrel Hill North, and the inspection is free.

You go down after a storm and find water across the floor with nothing to point at as the source. Water builds up in the ground outside, presses in at the joint where the wall meets the floor, and comes through wherever it finds the easiest path. Which is why patching the wet spot almost never lasts. In Greenfield we see it most in houses where the ground slopes back toward the building.

Basement waterproofing gives that water somewhere to go instead of trying to hold it out. A channel is cut around the inside edge of the slab, perforated pipe is set into gravel below floor level, and everything runs downhill to a sump basin. The pump lifts it and sends it well clear of the house. Wall vapour barriers direct anything coming through the block down into the same pipe rather than onto the floor. The concrete goes back over it, so nothing is visible when the work is done. Where the wall itself is weeping rather than the joint, the barrier is taken higher so the block drains from behind instead of being sealed from in front, which is what fails.

It will not fix a plumbing leak, and it will not stop condensation on its own, which is a different problem with a different answer. If your basement smells musty but the floor is dry, say so, because that changes what we recommend. Homes from Squirrel Hill North to Brighton Heights get the same inspection either way, and it costs nothing.

Water on a hillside does not sit still, it travels, and a house built into a slope is standing directly in its way. More people call us about this than anything else in the city. You see it as a patch of yard that stays soggy for days, or a puddle beside the wall that never quite dries. Ground around Brighton Heights holds water long after the rain has stopped.

A french drain intercepts it. We dig a trench along the uphill side of the problem, line it with filter fabric so it does not silt up, lay perforated pipe on a slope, and backfill with washed stone. Water in the soil finds the stone, drops into the pipe, and runs away downhill to daylight or a dry well. Where downspouts are dumping at the wall, we tie them into solid line and carry them out too, which is often half the problem on its own. Depth matters more than length here. The pipe has to sit below the level the water is travelling at, which on a slope means following the grade rather than the property line.

It works on water in the ground. If your basement is taking water through a crack in the wall, that crack still needs sealing, and we will tell you so rather than sell you a trench you do not need. Regrading is sometimes the cheaper answer and we will say that too. We cover Greenfield and the rest of the city, and the estimate is free.

Most Pittsburgh houses have basements, but plenty of additions and older sections sit over a crawl space, and those are where the musty smell usually starts. Bare earth gives off moisture constantly. That damp air does not stay put either, it rises through the floor into the rooms above, which is why the smell turns up in a hallway nowhere near it. Squirrel Hill North has a good number of homes with a crawl under part of the footprint.

Encapsulation seals the space off from the ground. A heavy liner is laid across the dirt and run up the walls, with the seams taped and the edges fastened and sealed. Vents to the outside get closed, because outside air in summer carries more moisture in than it takes out. A dehumidifier set to drain keeps what is left under control. Where water is actually pooling down there, drainage and a sump go in first, because a liner over standing water only hides it. The liner is run up over the top of the footing and sealed to the wall rather than stopped at the base, because that joint is where most of the moisture was getting in.

It will not carry structural weight. If the floor above is bouncing or sagging, that is a support problem and needs jacks or new posts, not plastic. We check for both while we are down there. Homes from Greenfield to Brighton Heights get the same free inspection, and you get told plainly which of the two you actually have.

People usually find out their pump has died during the exact storm they needed it for. Everything else in a basement system collects water and steers it; the pump is what lifts it out of the building. Age is the usual reason, and a pump that has run hard for years in a Brighton Heights basement will not last much longer.

Installation starts with the low point of the floor. A basin is set into the slab so the surrounding drainage can feed it, and the pump sits inside on a solid base rather than on silt. A check valve stops the water it just lifted from running straight back down the pipe. The discharge line runs outside and away from the foundation, not to a spot two feet from the wall where it soaks straight back in. A battery backup keeps it running when the power drops, which in a bad storm is exactly when it will. Two pumps in one basin is worth it on a house that has flooded before, the second set slightly higher so it only wakes up when the first cannot keep pace.

A pump on its own does not waterproof anything. If nothing is channeling water toward the basin, the pump sits dry while the far corner of the basement floods. It works as part of a system. We look at what is already in place across Greenfield and the rest of the city before recommending anything, and that look is free.

When a floor upstairs feels springy or slopes toward one wall, the reason is usually a few feet below it. Posts settle into soft ground, beams sag between supports, and joists that have sat in damp air for decades lose the strength they started with. You feel it as a bounce when someone walks past. Older sections of Greenfield homes tend to show this before anything else does.

Repair rebuilds the support underneath. Failing posts are replaced with adjustable steel columns set on proper concrete footings, so the load has something solid beneath it instead of bare dirt. Sagging beams are jacked back up slowly, over days rather than hours, because bringing a floor up too fast cracks the plaster above it. Joists that have gone soft are sistered with new lumber alongside the old, and any rotted ends get cut back and supported properly. Footings are poured under each new column rather than setting it on the dirt, because a steel post on bare ground punches down into it and you are back where you started in a couple of seasons.

Lifting a floor does not stop the damp that weakened it. If the ground down there is wet, that has to be handled too or the new timber ends up in the same condition as the old. We look at both together. Homes from Squirrel Hill North to Brighton Heights get a free inspection, and you will be told which part is urgent and which part can wait.
