Basement Waterproofing And Other Services In The Lutherville-Timonium Area

The Lutherville-Timonium area homes in particular have a unique set of problems which require different solutions to repair the problem at hand. Some basement water problems can simply be resolved by grading the slope of the landscape and extending the downspouts to redirect the water away from the foundation. Other problems require a different approach.

This is because the age of the neighborhoods in the Lutherville-Timonium area vary significantly, and thus require custom drainage and waterproofing solutions.

Considered a historic district, some of the homes built in Lutherville date back to as early as 1852. Each home is structurally unique, requiring a unique waterproofing approach for homes affected by basement leaking and water intrusion.

The foundations in the Lutherville-Timonium vary greatly – from stone, brick, cinder block, and poured concrete – depending on the age of the home and the builder.

Oriole Basement Waterproofing has vast structural experience in all building scenarios, such as in the historic Lutherville-Timonium area, and offers custom solutions for any type of foundation.

If left unresolved, basement waterproofing problems in the Lutherville-Timonium location eventually lead to more complex issues such as mold growth and structural problems.

Each year, the City Paper focuses on one specific industry and ranks all of the contractors in that industry. For example, one year they might rank electricians, the next plumbers, the next roofers, and so forth.

In 2007, the City Paper ranked Basement Waterproofing Companies and Oriole Basement Waterproofing, Inc. won the “Best of Baltimore” award.

Below is the City Paper article excerpt from 2007.


“Getting someone to work on your house for a reasonable price–and without dragging the project out twice as long as planned–is pretty much a miracle. And after researching and interviewing waterproofers, the odds looked worse. We got estimates all over the map, conflicting information about the only way to do it, people we almost had to physically eject from our house because they wouldn’t leave unless we signed a contract for some crazy system. It was awful. And then we talked to Oriole Basement Waterproofers. The pitch from this local, family-owned and -operated firm was clear, concise, and within our budget. They offered a lifetime warranty–not our lifetime, mind you–a completely transferable warranty for the lifetime of our more than 100-year-old house. And this isn’t some fly-by-night operation that will shut down and leave your warranty useless. Oriole has been around so long it predates the major-league baseball team whose name it shares; the company was named after the state bird. Oriole did the work quickly and with consideration for our home. And best of all, our once perpetually flooded basement has been bone dry ever since.”
