"Tony Hall was awesome. I know of JES since they started in the area but never had any reason to request a free inspection until I wanted to assess the condition of my crawlspace prior to selling the house. I learned so much about the function of a crawlspace and the current condition of mine. His inspection did not reveal any emergent issues with my 25 year old house but he did take the time to show me about encapsulating my crawlspace which will improve insulation properties and keep the area just about maintenance free. Included is a 25 year warranty which is transferable should I sell the house. I completely recommend JES and their inspector Tony Hall. I will be calling them to inspect and make recommendations to my next home when purchased."

Basement Leak Repair questions, answered by experts

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

Inspect regularly for clogs, clean drain lines, and ensure grading directs water away from the foundation.

In some cases, operating a snake can damage your drain and pipes. This depends on the overall condition of your pipes and how gently you operate the auger. For instance, older galvanized pipes covered in zinc are susceptible to scratches when using a drain snake. Additionally, it’s common for newbies to apply too much force when extending the snake, leading to scratches and related damage. You can also crack the porcelain with an electric auger if you’re snaking a toilet drain. If you’re using a manual snake or auger, the risk is minimal.

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.
