Moisture: The benefits to getting rid of basement dampness

by Diane B. Sullivan 07/07/2025

Water penetrations can significantly damage your house and create unhealthy living conditions. When water seeps into basements, the sometimes dark and humid conditions can create a perfect storm of health hazards. Even lower levels that have been converted into brightly illuminated living spaces are not immune to structural damage and potential mold growth.

Here are a few extra reasons to treat sub-level moisture as soon as you can.

Eliminating Moisture Keeps Insulation Effective

An unfinished basement typically includes insulation between the floor joists. If you are standing in the basement, the batts are usually stapled or tacked to the wood joists overhead. In some cases, they are covered by an insulating wrap. Even though common fiberglass insulation may not succumb to mold growth or water absorption, the batts may sag prematurely. This creates gaps that allow air penetration to impact utility bills. A dry basement is less likely to experience sagging insulation.

Preventing Water Seepage Maintains Structural Support Integrity

It's not uncommon for older homes to be supported by thick timbers. These supports are typically set on stone or concrete footings and bear the central weight of a structure. When even an inch or two trails across basement floors, it has a negative impact on the integrity of the timbers. And, keep in mind, older homes generally do not have pressure-treated lumber that stands up to water.

Keeping the basement floor consistently dry protects wooden supports and reduces potential floor sagging. A securely dry lower level also helps homeowners avoid the cost of bringing in construction professionals and an engineer to install new supports and level floors.

A Dry Basement Promotes Healthy Living 

Although mold growths have garnered splashy headlines in recent years, damp basements are also breeding grounds for other contaminants. Health hazards such as bacteria, fungus, dust mites and pests, such as powderpost beetles, can be triggered by moisture. Also, even small pools of water round out an environment that sustains creatures such as mice, snakes and a wide range of bugs. By contrast, a dry basement acts as a deterrent to unwelcome visitors.

Homeowners who take proactive measures to keep basements dry act in the best interest of themselves and their loved ones. By preventing water penetrations and excessive moisture levels, you save money, maintain robust property values and enjoy the healthy living environment they deserve.
