"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."

"I was very pleased with the work that the Enviropro team completed in my basement with the installation of the drainage system. Mike took the time to really walk thru project details and answer any questions prior to the project. The team arrived onsite the first day of the job and walked thru to explain the work they would start. They communicated any questions throughout the project and I was highly pleased once the job was completed. I would definitely recommend Enviropro for basement waterproofing needs."

"Working with Just Dry Basements was best described as no-nonsense, fast, and high-quality. In a highly-charged emotional situation like a basement flooding - it is easy to just pick someone to do the work out of desperation. I was lucky enough to work with JDB, who not only rapidly assessed, made a plan together on how we would approach the job, and accommodated a difficult situation where the basement was mostly finished, and they had to carefully deconstruct some of the walls to put in the proper mitigation. A year plus later and a LOT of rain past, the work truly stands the test of time and whatever the elements can throw at it. I have since worked with JDB on other projects, and not just because of the quality of work, but also their fair pricing, friendly and predictable communication, as well as standing behind their work 100%."

Basement Waterproofing questions, answered by experts

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

Yes, professional installers use weather-resistant materials to protect the dish and cabling from environmental damage.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.

In perfect conditions—meaning, no overexposure to the elements without roofing material on top of it—an ice and water shield can last for decades. In fact, many come with a limited lifetime warranty because they should last for a long time. If, however, the membrane is exposed to the elements during building or if there is a delay in installing the roofing material, it might only last up to 180 days if exposed to the elements. The key is to make it a layer of protection and then protect that layer by installing the roofing.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.
