Install A Maintenance Free Ventilation & Moisture Control System

The air in your home can become unhealthy due to excessive moisture, mold, or mildew. Repeated exposure to excess humidity and moisture can narrow your airways making it more difficult to breathe. Basements are more susceptible to retaining humid air than other areas of the home. The standard practice for basement ventilation in older homes was to vent basements with outside air. However, during seasons like summer when the air is very hot and humid it will retain more moisture without a way to dissipate.

We install ventilation systems that will prevent humid air from entering your basement as well as keeping your energy bills low. Our quality and environmentally safe moisture control systems are built to last and restore air quality to your basement.

Do You Have Poor Basement Ventilation?

There are three easy to spot signs that your basement may be poorly ventilated. Humidity is the biggest indicator. If your basement feels damp or sticky that’s a sign that your basement is too humid. The second sign is a musty or stale smell in your basement. Without proper ventilation, any lingering odors cannot escape and get trapped in your basement leading to a stale smell. Lastly, if you notice any health-related symptoms such as asthma, allergies, headaches, or shortness of breath that is a sign that your basement is not getting enough air flow.

How To Improve Basement Ventilation

Check for Standing Water

Any sources of standing or groundwater water will create problems in your basement. Mold can begin to grow on water within 48 hours if left alone. Foundation cracks are a common source of water and moisture in basements. If the foundation is structurally sound, a good sump pump and drainage system are crucial in keeping your basement dry and free from groundwater. We offer a lifetime warranty on our sump pump systems.

Sealing Basement Walls & Floors

While a sump pump and drainage system protect your basement from water, moisture and humidity can still get in. Concrete does not stop moisture or humidity from passing through, especially if the soil outside your basement is consistently damp or wet. We seal the basement walls and floors to prevent excess moisture from getting trapped in your basement.

Improving Air Circulation

With water and moisture under control, air flow is the next way to improve the air quality in your basement. The musty and stale smell come from air that is poorly circulated. Our team installs ventilation systems to improve the air flow and remove humidity. Our basement ventilation systems are energy efficient and strong enough to keep your entire basement dry.

We had some miscommunication about one aspect of the job, but the president of the company and one of their associates took care of it and demonstrated that they will stand by their product and service. I will definitely recommend them to others.”

I recently hired them for a water issue in one of my rental properties. They were prompt, courteous, and went above and beyond the initial contract. The owner Andrew came out to the house twice and met with me to see how things were going. The crew was mindful of the tenants in the home and completed the job within the specified time frame. Definitely would recommend this company to anyone in need of Waterproofing services.”

Jarred U., Pikesville, MD

“After the major storm from December, my basement was a complete disaster. The foundation was exposed and the wall was crumbling into the HVAC Unit. After the terrible experience with the previous contractor, I am very thankful I contacted you. You went out of your way to inspect the property the next day as promised, and were able to get the job scheduled the very next week. Your prompt and professional way of doing things took a lot of stress off of our family.”

Thomas & Margaret B

“My husband and I are very satisfied with the work that we received. We called late afternoon on Saturday and Andrew showed up 40 minutes later and made us feel confident that we would be water free after work was done. He was very knowledgeable. To our surprise, he was able to get a crew out the very next morning (Sunday). The crew was excellent. They finished the job in one day and cleaned up all their mess. Thank you! You were all great!”

Thank you Mr. Andrew and your staff. This is my second post.”
