"This was a huge job. A complete basement waterproofing - new internal drains installed and two new sump pumps installed. The guys were great - came on time worked hard all day and cleaned up after themselves. The only negative was at the completion of work when it was time to pay the amount was less than what was originally quoted. I told the guy that and he insisted that it was what he had. I even showed him the quote on paper. I paid it - glad it was less, but a few days later got a call from the office telling me I needed to pay another $1600 (the difference between the original quoted price and at the time of service price) I told her what the guy told me and she got a little rude saying "well you knew what the quoted price was" - yeah I DID know and was prepared to pay but after install HER guy insisted it was the price he had. I wasn't trying to get out of paying but the confusion on how much it costs was with the people working there. I didn't appreciate her attitude as if I was trying to skimp out of paying. Nevertheless, I ended up with this additional payment. However, the work is supposed to be guaranteed for life. No complaints there."

"The salesman, Bob took his time to thoroughly review the problems, offer solution options and respond to questions at the time of estimate and afterward, until I made my decision. He even pointed out foundation issues that I hadnâ t noticed and no other company that provided estimates picked up on. The crew came when scheduled and worked several long days to get the job done. They were always friendly, courteous and willing to answer my questions. They cleaned up constantly, to keep the area tidy. After completion, the dehumidifier needed adjustment and Brian came back immediately to address it. This was no small job. I had a long-standing major water problem in my basement, which can be expected when you live at the bottom of the hill. The basement looks better. The basement smells better. The foundation was repaired. The sump pumps and dehumidifier are doing their jobs. We havenâ t had any rain yet, so I cannot comment on how things will be with an onslaught of water, but I feel confident that the new system will far exceed the old one. Iâ m also confident that if there are any problems, Completely Dry will respond quickly."

"I thought my husband and I would contribute to Alex's reviews since we spent time with Jose and his team for the 3 days at Alex's house. We were amazed at how much attention was taken to ensure all our furniture and belongings were covered to mitigate dust. We are so completely satisfied with the dedication and expertise of Jose and his team. They left the basement in the best condition it was ever in. Very neat and clean, a great looking job. Kudos multiple times over for the finest production job we've seen in a very long time. They installed the interior drains and sump pump as well as a dehumidifier. No more dark, dank basement. It was an excellent experience. Thank you, Lon, Amber and Jose and team. Also a thank you to Jack Roadcap who recommended Lon to us. Warmest regards, Mary Ann Pinamonti"

"The required fix required that outside trenching be done and B-Dry does not do this type of work. The representative was very knowledgeable about the problem and apologized for not being able to solve the issue. Very much appreciated his honesty."

Basement Waterproofing questions, answered by experts

Regular inspections, maintaining proper grading around the foundation, and keeping gutters clear are advisable. Vapor barriers and sealants may need checking for wear after several years.

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.

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.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.
