"Excellent all around experience!!!!!!!! After a series of storms and gradual water soaking our basement carpet several times, I finally called Waterproofing One in April, 2017 after seeing their ad several times on our St. Basil's church bulletin. I spoke initially with the owner-Joe who was helpful and he dispatched Dave Cook who came over within an hour. Dave Cook has been in this business and related utility engineering previously for over 30 years and really knows his stuff. Dave was extremely thorough, spending time in the basement, looking at some pictures I took of the damage and spent a considerable amount of time walking around the exterior of my property and reviewing the landscaping where most problems start. Dave wrote up a report of what work was needed including extending downspouts, recommending we have our contractor add a louvered door at the top of the steps for aeration (a great idea given no windows in basement) , waterproofing the well water closet walls, spraying impacted area for potential mold, and installing a new French drain and sump-pump system with battery backup. Gene and his crew then came over on May 17, 2018 and performed the construction and installation work and did a great job. Those guys worked extremely hard in what is inherently a muddy line of work and were very courteous, professional and left the basement very clean. Gene took extra time to show us exactly what they were doing as they drilled holes into the lower cinder block walls, laying of the perforated pipe and some of the damp mold on the wooded studs he extracted at the impacted area. We paid exactly what Dave originally quoted! Dave Cook came back checked on things and made some other recommendations including adding stones around the foundation outside and in holes to avoid soil erosion and soften the acceleration of rain water into the ground. Once the work was finished and our carpenter redid the walls and painting, We had subsequently refinished the basement with high end vapor/mold resistant padding from Mohawk and a quality polyester carpet. 15 months later and here we are on September 30, 2019 after 50+ rain storms since installation and NO WATER nor Mold issues in the basement!!! We are really enjoying our basement again thanks to WATERPROOFING ONE!!!! 5-STARS!!!!!!!!"

"Basement Waterproofing Nationwide did excellent work in a timely and proffessional manner for a reasonable and appropriate fee. They said they would complete the work in 1-2 days and were done in one day. They were very careful and left things neater than they were before they came. We have used them before with great success and would use them again. So far, the problem we had, water in our basement, has not recurred, and our basement is bone dry. Tnank you Basement Waterproofing Nationwide."

"Every phase of the basement waterproofing project was first-rate. Through sketches, the inspector/technician took the time to explain how a sub-floor pressure relief system works. In a knowledgeable and professional manner, he designed the system for our basement and presented a detailed project proposal with drawings. An affordable cost estimate was reached. Also, financing guidance was given to obtain a deferred interest loan. Three days later, the construction crew arrived to begin installation of the system. They were attentive to specific concerns and answered all questions completely and politely. Through discipline and hard work, they completed the job in two days, one day ahead of schedule. Upon completion, including a thorough clean-up, a tour was given of the newly installed system. Dry Tech Waterproofing Systems is a high quality and efficient company that I will highly recommend to family, friends, neighbors, and others."

"We had numerous issues with water in our basement in the 5 years we owned our home, it was not an easy fix and we received numerous ideas and quotes. The rep from Worthington came out and was amazing, did not try and up sell us, and identified and fixed every problem. Worthington was not the cheapest firm we spoke with but would you really want the guy with the lowest price for a job like this? We would recommend this company emphatically."

Basement Waterproofing questions, answered by experts

There are a few downsides to a wet room, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.
