"Hello, we recently got an evaluation. Dylan was great and knowledgeable. He even found a diagnosis underneath our house about water running that we weren’t aware. He, with his awesome customer service, made us feel comfortable and confident on having him checking around our place to get our estimate done. Thanks s much Dylan and Mount Valley Foundation."

"Mgr Jeffrey offered free estimate next morning. Had two outdoor hoses were unable remove from hose bibs; were seized on. afraid needed new hose bibs! BG sent tech Joseph Lopez who was professional, knowledgeable & personable. After assessing bibs advised cost for removal of hoses and/or to install new bibs. i gave the go ahead to do his best to remove hoses! noted he consciously covered his shoes when coming through home from front to back yards. He patiently & carefully tried a few removal methods including the spray/wrench we had tried. He was finally able to remove them by carefully using a hack saw! He also installed a new hose connecting part on ea bib w/new threads that are guaranteed 2 yrs. It was third of the price new bibs would have cost! We so appreciated the extra conscientious efforts Joseph Lopez made to repair the hose bibs giving us excellent results at economical price! Thank you! again, we are very happy satisfied customers of Benjamin Franklin Plumbing"

"Everyone we dealt with from Cantey Foundation Specialists were very professional, timely, and caring throughout the entire process from job estimate to the actual work done. While the work done did not bring all areas back completely to their original states, with the exception of one area, they were all pretty close. Realistically, It's very difficult to fix in two days what has taken place over a period of years. I am very satisfied with the job done. Grayson (job estimator) and Estevan (crew leader) were very helpful and great to work with through the entire process."

Basement Waterproofing questions, answered by experts

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.
