The Best Basement Waterproofing Company in Baltimore City Since 1987

Basements in Baltimore get wet. It’s an unfortunate reality of homeownership here, and though some areas in the city remain drier than others, almost no basement is completely safe from moisture of some kind.

Upgrading or installing new sump pumps along with properly repairing foundation fissures and cracks are critical and necessary for homes prone to water seepage. However, having a professional basement waterproofing installed is the ultimate solution for a dry basement.

With our expertly and properly installed basement waterproofing, Baltimore City basements stay dry under any and all conditions. A waterproofing system solution from Basement Waterproofing Nationwide means that you can be confident that it will be properly specified, designed, and installed.

Some of the benefits of having a professionally installed basement waterproofing solution includes:

  • The prevention of foundation damage
  • Minimizing mold and mildew growth
  • A reduction of your energy bills
  • Increasing the resale value for your home

So, for your peace of mind, consider basement waterproofing for your home.

Foundation Repair

On the Bright side, many older homes have withstood the worst that nature and the elements can throw at them and are still standing proud. In addition, these homes often exude a sense of being a part of the landscape with their mature trees and greenery.

However, time and the seasons can still wreak havoc on older homes. And not-so-old homes, as well…

Any home is vulnerable to the ravages of time and weather, and despite the most diligent efforts at home maintenance, things happen.

With the older age of many communities within the City of Baltimore there is also a large number of homes built on stone or brick foundations, materials that are not in common use for foundations today. These foundations can often leak for different reasons than today’s more modern cement block and solid concrete foundations. As such it is imperative to identify the source of the water and address it appropriately so as to not cause more problems, often structural, as a result of the misapplication of traditional waterproofing methods. Your qualified inspector would take these factors into consideration before making a recommendation.

As it happens, older structures are more likely to develop foundation issues. The likelihood of this occurring – and the severity of damage – depends on several factors. For example, determining how long a foundation will last is partly dependent on the quality of the buildings construction and the type of materials used to lay the foundation.

The good news is that BWN provides expert and affordable foundation repair for residents of the city of Baltimore. In fact, we’ve offered foundation repair services Baltimore City homeowners have relied on since 1987.

Sump Pump Repair

Sump Pump Replacement & Installation Done Right in Baltimore City

Basements in Maryland and in the city of Baltimore are prone to water seepage.

And this can happen even without cracks in the foundation or basement walls. Seepage can be the result of surface water run-off after a storm that has leached deep into the ground and found its way into a basement. Most of the time this will occur along the floor and wall joints.

Then there are issues with the occasional flooding that can happen. As the state of Maryland’s Department of Emergency Management (MDEM) points out,

“Maryland is subject to flooding from several different sources. Flash floods tend to come after short periods of heavy rain and most often affect small streams and creeks. General flooding comes from more prolonged steady rain and tends to affect larger streams and rivers.”

And this certainly includes Baltimore City.

The standard solution for managing these intrusions of basement water is having a built-in sump pit with a reliable sump pump installed.

A reliable and working sump pump is critical for efficiently removing any water build-up from a serious storms and minor flooding. Typically, flood waters begin pooling at the lowest point in a home. And in many homes in Baltimore, the basement is that point.

Without a working sump pump, the pooling water can damage items stored in a basement, as well as cause rot, trigger mold growth, warp wood structures.

The good news is that for fast and efficient sump pump repair or replacement, homeowners in the city of Baltimore have relied on BWN for over three decades.

While Baltimoreans are justifiably proud of their city and consider it a special place, being an independent city means that it is special in its own right.

Of course, with a population of more than half a million people, one would be quite correct in assuming that there are a vast number of homes in Baltimore City, or Charm City, as it is still fondly referred to. In fact, according to the Baltimore Business Journal, the city had 294,858 housing units within its city limits in 2019, with 139,053 dating back to 1939 or earlier.

When you factor in the commonly accepted estimate that 30 to 35 percent of Maryland homes have basements – except those on the eastern shore of the Chesapeake Bay – that means well over 80,000 basements are in Baltimore.

And what all these basements have in common is that they can leak.

Which is why Basement Waterproofing Nationwide has specialized in fixing basement leaks and waterproofing basements in Baltimore for almost 30 years. To date, BWN has 16,000 clients in Baltimore City, totaling $22 Million in basement work completed.
