Crawl Space Encapsulation for Moisture Control in Newcastle, ON

Crawl spaces are known to be dark, muggy, and often places we homeowners wouldn’t choose to go to unless completely necessary. However, many homeowners don’t understand how essential a crawl space is to the rest of the home. Your crawl space is a buffer between your home and the wet earth below. Unfortunately, as your crawl space works to protect your home, it can also collect too much humidity from water collection.


Newcastle, ON, homeowners were experiencing a muggy stench lingering around. System Design Specialist Mark Dougherty recommended our CleanSpace® solution. Installed by Foreman Dave Jackson, he was able to encapsulate the area that would provide numerous benefits for the space. After they were done, the homeowners could not believe how immaculate and bright their crawl space looked! Not to mention the immediate improvement of air quality throughout the whole household.

Crawl spaces often get neglected and can cause a massive disturbance to a home's structural integrity, air quality, and smell throughout the house. The homeowner, Val, was bothered by the moldy smell that increased in the warmer months. She worried the house could collapse from all the moisture. Clarke Basement Systems was her first option for a permanent solution. The crawl space had never been encapsulated and it needed a lot of dirt/debris removal before starting work. Our System Design Specialist, Mark Dougherty, went to the home to analyze the situation in person. The complimentary inspection dives deep into the root of the moisture issues and if any additional problems could cause harm in the future. Mark explained our products and services thoroughly to Val, and she immediately said, "Let's do it." Our Installation Foreman, Dave Jackson, and his crew went to the house to encapsulate this crawl space forever. The products used were:



Val was curious about the work, so Dave explained each product's function as it was getting installed. The work was completed without interruptions. Val was excited to know she would never have to bear that musty smell again. The Aprilaire® regulates the temperature independently, so maintenance is minimal. This crawl space will never be damp again.

Donna, a homeowner in Newcastle, ON., had a nasty smell throughout her house for a very long time. She couldn’t figure out where it was coming from. She felt so embarrassed by the horrible odour and wanted it removed immediately. Finally, Donna searched every nook and cranny in the house and found the smell coming from the crawl space vents. As she got closer to the vents, Donna felt a gust of humid air flooding out and began to realize a huge humidity issue existed in the crawl space.


Her friend in Wilmot Creek recommended that Donna give us a shout. Our Call Centre set up an appointment with our System Design Specialist, Ryan Hanlon. After his inspection, Ryan recommended a full crawl space encapsulation since it was completely bare and never waterproofed. The system included our CleanSpace® vapour barrier, drainage matting, vent covers, and SmartDrain™. To help create balanced humidity in the newly encapsulated crawl space, Ryan suggested our high-efficiency AprilAire® dehumidifier. Donna trusted Ryan’s proposal and felt confident the mouldy smell and mucky feeling would be gone for good. Our experienced Installation Foreman, Dave Jackson, and his crew went to Donna’s house and began installing her new system. The results were way above what Donna was expecting. The harsh, smelly summers are gone for good, and Donna could start enjoying her house again.

Crawl Space Encapsulation System in Newcastle, ON

Homeowners in Newcastle, ON, needed help with the high moisture levels in their crawl space. They noticed a damp feeling in the air of their main floor and a musty smell.

Installation Foremen Dave Jackson set up our CleanSpace® so that the ground moisture would not be able to vapourize into the crawl space anymore. Since 40% of the air on the main floor comes from the crawl space below, the homeowners noticed a huge difference in the smell and overall air quality!

Currently, my basement is leaking and I'm sure its from multiple places. The house is 110 years old and the basement is unfinished. There is a sump pump and it looks like the previous owners put in some very lackluster drainage. Water still floods sections of the basement when there's heavy rain falling or thawing. I want to know what options I have if we decide to tackle this issue. Repairing cracks, or if there are too many, expand the drainage to do a proper job.
