Basement Waterproofing

Nothing is more frustrating than dealing with a wet Elkins Park, PA basement. It can damage walls and flooring and ruin irreplaceable things like photo albums and family heirlooms. But knowing the causes of wet basements and how to prevent water damage can help avoid this frustration.

Foundation Repair

Many Elkins Park, PA basements have structural problems. The repair of these defects takes a professional to recognize and diagnose the multitudes of problems that can occur in basements. Foundation failures can include cracks, movement, leaning, bulging or bowing.

Exterior Waterproofing

An exterior drain system does not allow any moisture inside a Elkins Park, PA basement or crawl space. As apposed to an interior drain system, an exterior waterproofing system diverts all water before it is able to come in contact with your foundation.

Basement Remodeling

Tired of your dreary damp Elkins Park, PA basement? Think you should be using all that space for more than storage or laundry? You’re correct! Turn your basement into a beautiful finished living space.

They made sure the carpets were protected, they put plastic up around the job so dust did not go through the house, very professional and did a great job.

Thanks for your excellent work.  I know you are a man of your word and will finish the EZ Breath installation once the sheetrock is done. I did not see the need to hold the $100 as you suggested. I look forward to hearing from you soon about the estimate for re-finishing the sheetrock, and the estimate for laying down the vinyl flooring. Thanks again!

Joe Soster and his crew installed a basement waterproofing system and a sump pump in my home. The quality of work was simply awesome; the crew respected our home, worked hard, and produced a great final product. The price was very reasonable. I am very satisfied!

Thank you and your crew for working on the various parts of my house. You’ve helped me out in more ways than you could know, taking away much of the burden. I’m appreciative of the fact that you billed my only for the men’s time on the last day.

We called this company for a leak problem in my elderly mother's home on Sept. 19, 2018 and spoke to Terrance. Terrance said he needed to send one of his "guys" who subcontracts for him, due to lack of an available appointment. He sent Paul Dalessandro of WeatherTech ...

We had great experience with the owner Joe Solster. This time is the general contractor manager Eric. He arrived on time and checked everything thoroughly and completely. He explained what needs to be done and give us a very good explanation.

I have used Waterproofing One for two rental properties I care for, and have recommended them to friends and family. They have employed different methods depending upon what each one needs and each has been successful in heavy rain conditions
