Anne S.


Homeowner bought a house that had crawl space problems identified on home inspection report. After moving in, upgrades were completed for the kitchen including installation of new hardwood floors.

Several months after the completion of the hardwood floors, the owner became concerned about the crawl space moisture. She was worried the moisture could buckle and cup the hardwood floors. She decided it was time to re-visit the water in the crawl space and implement a solution to properly address the moisture levels under the house. She was referred to Dry Otter Waterproofing by her real estate professional.


Our representative met with the homeowner to discuss her concerns before completing a free crawl space inspection. Our inspection revealed evidence of groundwater penetration and standing water, deteriorated crawl space vapor barrier, light mold, and condensation on HVAC ductwork. Luckily, inside the house, the hardwood floors had not begun to show the signs of moisture. We sat down with the homeowner and reviewed the crawl space pictures. We discussed the problems and solutions, such as crawl space waterproofing to advance crawl space moisture control with crawl space encapsulation and humidity control.


Initially, the homeowner decided they only wanted to implement a waterproofing solution for ground water penetration. This solution involved an interior drain system, sump pump system, and a basic vapor barrier. Their hope was this solution would address the problem and a full encapsulated crawlspace system would not be necessary. We contracted and installed the agreed upon solution.

The homeowner continued to monitor the crawl space and confirmed via Dry Otter Waterproofing’s annual maintenance program the basic solution did not provide the crawl space protection and warranty she desired. Therefore, she contracted us for additional crawl space waterproofing with the WhiteCap Encapsulation System.

Our install crew removed the basic vapor barrier and installed an additional interior drain and sump system to provide waterproofing protection around the entire perimeter foundation. Next, we installed the WhiteCap Encapsulation System with humidity control. An additional sump system was necessary as this crawl space had 2 distinct low areas.

The crawl space encapsulation system involves wrapping the foundation walls, interior piers, and ground with a high quality durable reinforced liner. This process ends with taping all seams and sealing foundation vents.

Once done, an Aprilaire dehumidifier was installed to control air moisture. The homeowner has a complete crawl space moisture solution with long term warranty and the peace of mind that her crawl space water and moisture issues are resolved. Lastly, we’ll be there for her in the future to perform service and annual maintenance on all equipment installed.


“…offered me several options without being pushy or aggressive. The team has decades of experience and I would recommend Dry Otter to anyone who needs a reliable and professional company to help solve their home moisture needs.” Anne – Charlotte NC 28211
