Mr. snowden's Pest Control

Moisture Control

Moisture in your crawl space can lead to a number of issues, including mold and mildew. It can also cause rot and structural damage while becoming a very pest friendly environment. Mr. Snowden offers affordable options to eliminate these threats to your home and to your family’s health.

Mr. Snowden Can Solve Your Crawl Space Moisture Problems

Keeping your crawl space dry and free of moisture is an important part of maintaining a healthy home environment. Moisture makes it prone to rot and mold and attractive to insects, pests and living organisms. Mr. Snowden’s Moisture Control Solutions remedy those problems and more!


Encapsulation is one of the best ways to reduce energy costs, increase air quality and prevent moisture damage to your home. Encapsulation is the process of sealing your crawl space with a vapor barrier, including the floor, crawl space vents, foundation walls and supports. It requires the removal of any standing water in your crawl space prior to treatment.

It is accomplished by enveloping the surfaces of your crawl space with a waterproof vapor barrier that prevents the passage of moisture and humidity. Once completed, the relative humidity should stay below 60% and with dehumidification (strongly suggested), under 50%. The air should be conditioned with by either a small amount of supply from the HVAC system, a small exhaust fan, or preferably by a dehumidifier.

One of the greatest benefits of encapsulation is healthier living conditions in your home for you and your family. It inhibits mold, can lower your energy bills, make your heating and cooling equipment and ducts last longer and prevent costly floor repairs. Encapsulating your crawl space may qualify you for a rebate or tax incentive to mitigate some of the cost.

All bulk water problems in the crawl space must be addressed prior to encapsulation. Adding drain tile and a sump pump prior to encapsulation will further improve the effectiveness of the treatment. Advanced Energy Studies have found nearly 20% reduction in energy use in homes with encapsulated and conditioned crawl spaces.

Encapsulating your crawl space adds value to your home and improves the overall quality of living in it as well as decreases pest problems that originate from the crawl space.

Drain Tile

Drain tile is basically a pipe with holes or perforations and stone surrounding it.  The idea is for the holes or perforations to let water in so that it can then run toward the sump crock to be pumped out.  The stone protects the pipe from being crushed by the weight of dirt above it (and from rocks being dropped on it during back fill).  The stone also helps with the movement of water around the pipe.

Sump Pump

sump pump is a small pump installed in the lowest part of a crawlspace. Its job is to help keep the area under the building dry and to prevent it from flood­ing. Usually, sump pumps are installed in specially constructed sump pits. Water flows into the sump pit through the drain tile system. The sump pump’s job is to pump the water out of the pit and away from the building so the basement or crawlspace stays dry.

Dehumidification & Exhaust Fans

Dehumidification and exhaust fans greatly enhance the effectiveness of encapsulation in a crawl space. Dehumidification requires a way to remove the captured water, whereas an exhaust fan needs an egress for the exhausted air. Exhausting is much less expensive to install and to operate, with dehumidification being more effective at lowering humidity. Both are most effective in a properly encapsulated crawl space.
