Questions we get before the estimate.

It depends on how much wall you need to drain and what the ground is doing, which is why every estimate is free and in writing before anything starts. Most Lancaster County jobs land between a single-wall drain and a full perimeter system with a sump, and as a guide, national cost data puts that work at about $3,000 to $7,000 for one or two walls and $6,000 to $12,000 for a full perimeter. There is no money down and financing is available.

No. A Basement Gurus estimator comes out, reads the water path, and gives you a written scope and price at no cost and with no obligation.

Yes. We document the damage properly and deal with adjusters regularly, particularly on water and mold claims.

The length of wall being drained, how many sumps and whether they carry a battery backup, any wall barrier or crack repair, where the discharge line ends up, the warranty, and a fixed total. Two estimates that look far apart usually differ on one of those lines, so compare them line by line.

No. The inspection and the written estimate are free, there is no money down, and financing is available. You get the written scope and a fixed price before anyone touches your house.

Because that is when the soil around the foundation fills up. Saturated soil pushes water through cracks, porous block and the joint where the floor meets the wall, and the ground under the house sets the timing: limestone delivers it within the hour, while shale clay holds it against the wall for days. Gutters that dump water beside the foundation make both worse.

On a damp wall with no running water, a masonry sealer can help. It will not hold back water under pressure, and once the soil outside is saturated, pressure is what pushes water in. Sealers work best as an extra layer over a drainage system.

Often more than anything else. An inch of rain on 1,000 square feet of roof is about 620 gallons of water, and a downspout that ends beside the wall puts its share straight into the soil against the foundation. Extending or burying downspouts is one of the cheapest fixes there is.

Basement Gurus fixes wet and leaky basements across Lancaster County from its office at 2348 Harrisburg Pike in Lancaster, as a family-owned, licensed and insured company with 22 years in business and an A+ BBB rating. An estimator reads the water path at a free inspection and gives you a written scope and price, and the waterproofing systems carry a lifetime warranty that transfers with the house when you sell.

Yes. Water rising through the slab or along the floor-wall joint usually means the water table under the house is high, which is common on the river terraces and in low ground near creeks. The fix is drainage under the floor at the footing, tied to a sump, because a wall coating does nothing for water arriving from below.

The EPA’s guidance is to keep indoor humidity below 60 percent, ideally between 30 and 50 percent. Basements here often read higher than that in July and August, when warm, humid air meets cool walls and floors. An inexpensive hygrometer tells you where yours sits.

A musty or earthy smell is damp material: block, wood, cardboard, carpet or drywall holding moisture, often with mildew or mold starting on it. The smell returns as long as the walls or floor stay damp, so find the moisture first and treat the smell second.

For a small patch, often yes. The EPA’s guidance is that an area under about 10 square feet, roughly 3 feet by 3 feet, can usually be cleaned by the homeowner. Larger growth, mold that keeps returning, or mold inside walls and insulation calls for containment and professional removal, and either way the moisture behind it has to be fixed.

Fast. The EPA’s guidance is that wet materials dried within 24 to 48 hours usually will not grow mold, so after a flood the priority is getting the water out and the air moving: pump or vacuum it up, pull wet carpet and cardboard, and run fans and a dehumidifier.

Thin vertical shrinkage cracks are common in poured walls, and they are usually only a water problem, which injection takes care of if they leak. Cracks that are wider at one end, run horizontally, or come with a wall that leans or bulges are the ones to have measured, because they mean the soil is pushing.

Saturated clay pushes sideways on the wall, and freeze-thaw in that wet soil adds to the load every winter. Block gives at the mortar joints first, which shows as a horizontal crack partway up the wall or a stair-step crack near a corner. Relieving the water and reinforcing the wall are the two halves of the repair.

Most can be kept. Repointing the failed mortar and dealing with the water that washed it out is what keeps a stone wall sound, and a whole stone foundation typically costs $3,500 to $10,000 to repoint, a fraction of lifting a house to replace one. Loose stones can be reset as part of the same work.

Most interior drainage and sump installations are one to three days. Foundation stabilization is usually a day. Encapsulation runs two to four days depending on the size of the crawl space.

No. Crews work in the basement or crawl space, contain the dust, and clean up at the end of each day. Mold remediation is the one case where we may ask you to stay out of the immediate area.

Interior drainage can go in any month, since the work happens inside. Spring thaw and summer storms are when Lancaster County basements show their problems, so that is when most people call, and a fall or winter install has the system working before the next wet season.

The interior work, yes: drains, sumps and wall barriers go in year-round because the crew is working inside. Frozen ground is what can delay exterior digging, so outside drainage sometimes waits for a thaw.

Basement Gurus runs a 24/7 emergency line at (800) 834-6584 for flooded basements anywhere in Lancaster County. The estimator reads the water path and gives you a written scope and price for the permanent fix at no cost. If a system Basement Gurus installed ever takes water again, you call and the crew comes back, because that is what the warranty is for.

Our waterproofing systems carry a lifetime warranty, and it transfers with the house when you sell — which matters more than most homeowners realize at closing time.

You call us and we come back. That is what the warranty is for, and it is why we would rather size the system correctly the first time than win a job on price.

Every few months, and always before the wet season: pour a bucket of water into the basin and watch the pump switch on, empty it and shut off. Check that the discharge line outside is clear and pointing away from the house, and test the backup’s battery alarm the same day.

Very little. Keep the lid on the sump basin, test the pump a few times a year, keep the discharge outlet clear of leaves and snow, and keep the gutters clean so less water reaches the wall in the first place.

Our Lancaster office is at 2348 Harrisburg Pike. When you call, you reach our team — not a national call center routing your address to a subcontractor.
