We offer you the best possible solution to your particular needs, offering a wide range of internal or external solutions. Our business owner Dean has 40 years experience specializing exclusively in basement waterproofing, his work has been recognized and featured in “This Old House Magazine,” showcased on our website: dirtydeedswaterproofing.com Give us a call to schedule your free inspection to identify, mitigate, and resolve your water issues.

"My sewage ejector pump in basement would not stop running and I was looking to replace it. I texted Dean two pictures of the pump, he was able to give me a quote over text and the price was quite reasonable. He received a new pump on 5/22/2023 and came over to my house. After opening up the old pump and checking, he told me that the only thing that is really broken is the check valve, the switch got stuck but is still functioning, and the pump itself works fine. I ended up asking him to only replace the check valve and the switch and this saved me about $1000 from the original plan. I appreciate Dean's honesty, professionalism, and a job well done."

"Excellent - Tito was extremely responsive and his team did excellent work. I shopped around and got multiple quotes, and his was the lowest. More importantly, he had done work on a number of my neighbors’ homes and came highly recommended. His team was very responsive and got the work done on a short time frame which was great because I needed much of the work done before I moved in to my new home. My floors and skylights look great and I have full confidence in his work. One thing which I really liked is the fact that he is constantly in communication, is always available, and is local.

Basement Waterproofing questions, answered by experts

Installing storm windows can protect your home’s interior from heavy storms. Most storm windows are made with enamel-coated aluminum with screens and sliding glass panels. They also make your house more energy-efficient. The average storm window cost is $12,000, ranging between $4,250 and $19,850, depending on mounting, window types, glass types, and frame materials.

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

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.

The only real negative when encapsulating a crawl space is that the cost is high. It can cost several thousands of dollars to do this project. However, it protects your house and those in it by providing an energy-efficient space instead of one that frequently pools moisture and causes damage through mold growth in your home. While less common, another disadvantage could be encapsulation making access to pipes and electrical slightly more complicated in certain crawl spaces.

The easiest methods for waterproofing your basement include installing a gutter system to direct excess runoff away from your foundation and grading the soil away from your home to pull water away from the concrete. In some cases, these methods alone can be enough to eliminate water intrusion and moisture problems in your basement. If you have excessive rainfall in your area, though, you might need to employ more complicated solutions, like installing a French drain and a dehumidification system inside.
