Basement Waterproofing

The Best Basement Waterproofing Company in Montgomery County Since 1987

While new construction with freshly poured foundations and intact basements may be dry for a period of time, a few years of settling and soil movement can change things.

Basements are vulnerable to water damage because both concrete and soil absorb moisture. In addition, unless one lives in an extremely dry climate, soil stays relatively wet most of the year. And the soil around your foundation is much more porous than undisturbed soil since it is mostly compacted fill.

As one writer put it, “Most basements leak, eventually.”

A manufacturer of building products noted on their website,

“The most common cause of basement water in homes is from leaking wall cracks. Concrete walls will crack due to the release of water during the curing process. Cracks will commonly be found near breaks in the wall (such as windows and beam pockets) or in the middle of long walls uninterrupted by turns in the wall. These cracks will not automatically leak but often do. Surface repairs with rigid products such as hydraulic cement or epoxy will often fail again.”

In addition, basement moisture can be the result of trapped, humid air – which we have plenty of here in Maryland – or from groundwater that has wicked through the concrete and then seeps through the floor or walls. Even poorly placed or clogged downspouts can lead to water leaking into your basement.

Because water from the downspout to the underground drain occurs at ground level, close to the foundation walls, thousands of gallons of water a year can pool around and seep into the ground, if a clogged or poorly placed downspout is left unchecked.

And damp basements can give rise to a health hazard –mold and mildew.

Mildew and molds produce allergens and other respiratory irritants that can cause allergic reactions, especially true in sensitive people or those with respiratory problems.

The good news is that by opting for the solution of basement waterproofing, Montgomery County homes can be free from basement moisture, mold growth, and foundation damage that can result.

With professionally installed solutions for basement waterproofing, Bethesda homeowners and those in other Montgomery County communities can have basements that will stay dry in any and all weather conditions.

Foundation Repair

Get the Best Foundation Repair Service in Montgomery County

As homes get older, they are commonly said to settle, which sometimes accounts for sticky doors and occasional cracks in walls. The foundations of aging homes also “settle” and, in some cases, shift a bit.

This subtle movement can, however, cause damage to both the foundation and even the upper interior of the house.

How does this happen?

Typically, the movement of soil beneath the foundation over time can lead to minor structural damage in a foundation. We talk about houses and foundations “settling” but this dynamic is actually caused by soil movement due to water in the soil.

A common example is what is known as expansive soil. Because of its response to groundwater, it can repeatedly change shape, which has different effects on a home’s foundation. When that soil dries significantly, this can cause the soil to shrink, which reduces the soil support around your foundation.

Conversely, wet conditions causes this type of soil to expand, which then puts additional pressure against your foundation walls.

Either one of these soil movements can be damaging to a foundation over time. But when the soil repeatedly goes through these extremes year after year, a house’s foundation can suffer foundation – and basement – damage such as cracks and fractures.

Fortunately, when it comes to expert and affordable foundation repair, Bethesda, Chevy Chase, and other Montgomery County homeowners can count on BWN.

Sump Pump Repair

Sump Pump Replacement & Installation Done Right in Montgomery County

A common feature in most Montgomery County basements is a built-in sump pit with a sump pump installed. And the reason for this is that basements throughout Maryland are susceptible to water seepage, leaks, and even flooding. When leaking water begins spread or pool on a basement floor, a reliable sump pump can take of it.

But sump pumps aren’t always reliable.

As one insurance company put it, your sump pump won’t last forever. Averaging about 10 years, you might not notice your sump pump has malfunctioned until it has stopped working. And once it does, water damage to your home and the belongings within it can follow closely behind.

The good news is that when you need sump pump repair or replacement, Montgomery County homeowners can simply call BWN. For the best in sump pump installations, Montgomery County homeowners can rest assured that Basement Waterproofing Nationwide is their first choice.

Bethesda and Chevy Chase, located in Montgomery County, are known as leading communities and population centers. In fact, as one lifestyle blog has noted,

“Eighty-five percent of Bethesda residents have a college degree. What makes Bethesda one of the best-educated places in America?

The National Institutes of Health (NIH) anchors the local economy, and dozens of supporting private businesses have located or relocated to be close to the national center of medical research. The hundreds of Ph.D.s and MDs that work at public and private facilities account for Bethesda’s remarkable educational attainment levels.

When it comes to population: Germantown, adjacent to Rockville, and Silver Spring, between Bethesda and Takoma Park, are the two most populous places in Montgomery County. In fact, 13 of the 15 most populous places are all Census Designated Places.

That means a great number of large homes, which also means a large number of basements. Which means thousands of large basements.

And, as we all know, basements can leak.

Which is why the professionals at Basement Waterproofing Nationwide we have been helping homeowners in Montgomery County and communities like Bethesda for three and half decades. And how do we help? By repairing foundations and waterproofing basements in homes like those in Montgomery County since 1987. Currently, BWN has served over 7000 clients and delivered $16 Million in waterproofing services.
