Plumbing Problems

If there is a leaking pipe or faucet, correcting the problem will usually eliminate the moisture. Plumbing issues could be difficult to repair in older homes that have copper pipes, but most homes built in the last 30 years use standard piping that you can easily learn how to fix yourself. Don’t forget to turn off the main water feed to your home before performing any plumbing repairs to prevent causing additional damages.

Air Circulation

According to an article from Energy Star, air circulation is a leading cause of excessive humidity in the home. Replacing the filter in your air handler is one way to promote better air circulation throughout the home and basement. Other methods include installing and using vent fans in the bathroom, laundry area, and kitchen. Always make sure that clothes dryers are vented to the outside, as improperly vented dryers are a major source of humidity. You can install single room dehumidifiers if the problem is limited to specific parts of the home or basement, or contact an HVAC company for whole house solutions.

Roof and Ceiling

A minor leak on your roof can lead to problems with moisture and mold throughout the home. And while major roof repairs should be left to professionals, learning how to fix minor problems is not difficult. The main sources of minor roof leaks that you can fix yourself include:

  • Remove debris from the roof
  • Clean out and repair gutters
  • Seal around vents
  • Replace damaged shingles or tiles

Make sure that the flooring in the main part of the home is sealed against moisture. Floor sealants and vinyl flooring are both excellent ways to create a barrier against moisture rising up from the ground or basement. If you basement does not have a floor installed, put in a concrete floor, and the seal it to prevent future seepage.


The basement is a common source of moisture in the home that you can learn how to fix. Waterproofing sealants and paints can be applied to the walls and floor that act as a great barrier. The key to using sealants is that they have to be applied when the surface is relatively moist, and cannot be added over any existing layers of paint. If you cannot satisfactorily remove the existing moisture, it may be necessary to get assistance from a professional waterproofing company.

Your Home’s Foundation

If the foundation of your home has settled, there may be cracks in your basement floor or walls that need to be repaired before a sealant can be applied. Since ordinary caulks and paints will not seal a crack in concrete, it may not make economic sense for you to learn how to repair them yourself. When i doubt, you can always contact an expert, for an estimate on cracks repairs or basement sealants that you do not know to fix yourself.
