"These two gentlemen showed up everyday and on time with a smile on their faces. Yuni talked me through every step of the conversation process and was easy to work with. A Generous amount of care and professionalism went into my project. Their pricing will be hard to match for any of the big companies. I strongly recommend Dry Summer Waterproofing to anyone with crawl space problems like I had. They offer many other services that I will be using them for the future for."

"My experience was excellent, from initial call to completion of the work. Great team that showed up on time, conducted themselves well, and were committed to their work. Austin F. Conducted a thorough inspection and proposed a multistage plan to repair my crawlspace. I was especially happy that an engineering firm prepared final inspection and drawings for the county permit process. John, Austin, Taylor, and Chris worked very hard for three days, even in the rain and cold. Great company and people."

"Great! They quoted me a price, came to look at the house and gave a description of the work that would be completed. They came the next day and finished the job within two days. They were very professional, knowledgeable, and efficient. I would certainly hire Jim and his crew again."

"**Caveat emptor**. If you choose to do business with Mr. Clark, be certain to get absolutely everything he says IN WRITING! And make sure you are crystal clear about what you are getting for what you are paying. He charges a king's ransom for his work and will not acknowledge HIS MISTAKES!"

"We discovered mold around our vents inside of the house and called to have an inspection of our system. Eddie Geyer came to our home and was very professional (and polite) from the beginning to the end. We had several companies come out but chose this company due to their fair price, through inspection and professionalism. Mr. Geyer and his crew did an excellent job cleaning our vents (they had never been cleaned before). He answered all our questions and we feel confident that the vents are in much better condition now. I highly recommend this company."

Basement Waterproofing questions, answered by experts

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.

Interlocking garage tiles made with PVC are the most effective for garages with past issues of humidity and flooding because damp concrete is not suitable for paint. Epoxy coating is also water-resistant and can prevent mold buildup. Finally, porcelain tiles are a wonderful option for wet conditions if your budget allows.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage.
