 Your Home faces Water Damage

1. Delaware has an annual precipitation that averages about 55 inches statewide. That along with low land near the coast can lead to serious flooding issues

2. When flooding hits your area, your basement is most likely to be the prime target for water damage.

3. If you allow it to be wet, moldy, humid, smelly, and unhealthy, you're abandoning an entire floor of space in your home. Additionally, the basement air - filled with odors, dust mite feces, humidity, and mold spores - will rise into the rest of the house, ruining the healthy environment of the home.

    Customer Testimonial

              Very well taken care of, Any questions were answered. Computer generated quote on the spot. rom my first cold call to your office,, the entire process was well explained and organized, I didn't feel a need to look elsewhere. I might get something cheaper,, but,, do I WANT something cheaper? I own a lot of things I could buy a cheaper version of..... seldom the lower price is worth paying for. Got a quote that day - felt comfortable enough,, paid the down payment at the same time. The job was quickly scheduled.

    Customer Review

    By Nancy L.
    Annapolis, MD

    The competitors price was about the same - with Basements systems being just a little higher. The basement systems warrantee was better and the salesman from basement systems was very thorough and spent a lot of time with me talking through the options - I was selling the house and wanted the job done right in a very short time period and the salesman promised basement systems would meet my time constraints with a quality system and they did. I am very happy with the outcome.

Comment: Currently I have a soleus air conditioner that is inoperable. Fighting with that company has proven fruitless. I'm looking for a stalwart company that stands behind it's dehumidifying systems to help my basement air to remain dry and keep mold out of my life. Basement footprint is roughly 20x30 (guestimate). I am looking for a dehumidifier that drains directly into the dry sink or can otherwise be a "set and forget" situation.
