Why fix your basement water problems?

A wet basement is detrimental to both your house and your family. It prevents the use of valuable space, whether for living, storage, or other activities.

It also leads to unnecessary work and expense, including cleanup after periodic flooding and replacement of equipment such as ruined furnaces and water heaters.

In addition, a wet basement depreciates property value. In a today's challenging housing market, no discerning buyer wants a house with an unsolved waterproofing problem. Even basements that are merely damp should be upgraded.

Moisture promotes the growth and spread of mold and mildew, a common cause of indoor air pollution and respiratory illnesses.

Moisture can also ruin many of the items homeowners typically store in basements, including steel tools, books, and photographs.

Our approach to basement waterproofing

We begin by eliminating sources of water, especially rainwater that drains toward foundations from roofs. It's imperative to have gutters and downspouts that function correctly. In addition, grades, walkways, patios, and driveways must slope away from the house.

For basements where groundwater is the problem, the first choice is a below-floor interior perimeter drain, also called a French drain. The specially designed drain rests in a trench on top of the footing and is covered. Compared to exterior perimeter drains, interior drains can be installed in less time (typically a day or two), cost less (about half), are easier to maintain, and won't disrupt foundation plantings and other landscape features. In cases where the slab is thin, an above-floor drain is used.

The drain captures water that seeps in through walls or at the slab-wall joint. Whether the drain is above or below the floor, it channels water to a sump basin, where a sump pump moves the water through a discharge pipe to the outside. We do not rely upon coatings brushed on the inside of foundation walls to stop moisture penetration.

We install quality sump pumps and effective drainage systems to help keep basements dry.

    Customer Testimonial

              After living in Atlantic beach for 45 years with a rising fresh water table, 5 years of increasing incidents of fresh water intrusion ( sometimes up to 3 inches ) in the basement and a sump pump that wasn't doing its job I decided I needed help.After inerviewing 3 companies and a referral from a friend I chose Complete Basement Systems.In Novemer 2011 their engineer John Rosa came in, looked at my basement, listened to my concerns and came up with a plan. Install a French Drain system with trench drains strategically placed and a Triple Safe Sump Pump.The installation crew came in and installed the system and answered any questions I had. The installation was quick and extremely clean. The system worked as promised and my basement stayed dry.Along came Sandy.At the height of the storm surge we had 2.5 feet of water surrounding our home with tremendous pressure on the ground water.Not a drop in the basement. The pump was going off every 45 seconds. With no electricity for 15 day we were running our generator 20 hours a day, shutting down for 4 hours each day. When the power was off the battery kick in and the pump continued to to run flawlessly and kept our basement dry.I cannot recommend Complete Basement highly enough for their expertise, professionalism and customer relations they show from answering the phone to their engineering a system to the installion of the system. The Triple Safe Pump is a must.Again, thank you Complete Basement. Sincerely,John
