Planning to Buy a House? Look For These Signs of Basement Waterproofing Problems

Are you shopping for a new house? If yes, then it must be an exciting time looking for an ideal place in the best community with the best schools. There are bedrooms and bathrooms to be considered – and the granite countertops too!

Maybe not as exciting, but every part is as important, is the basement condition of your new home. You should not neglect the basement thinking its potential as a storage space because a bad basement can easily turn your dream home into a nightmare.

Here are the signs of potential basement waterproofing problems to make sure that your new home’s basement is dry, safe and healthy, and won’t cost you a fortune for wet basement service repairs.

Damp Odor

If a basement smells like a locker room, chances are there is water seeping into it. There may not be other signs of water infiltration but the odor always tells.


Black, green or white, whatever the color, the signs of mold in the basement are a serious concern. Not only you will have to get a water problem repaired, you’ll also have a mold remediation job to deal with.


If you spot a white, chalky substance on the walls, it is efflorescence – mineral deposits that come out of wall cracks and openings where water has infiltrated. Not a very serious situation but a bad sign.

Cracks in the Walls

You may not see water seepage signs yet—but foundation wall cracks never appear themselves and it’s only a matter of time before you’ll have to call wet basement service repair. The good news is that crack repair is not an expensive waterproofing job.

Bowed Walls

Do you see an inward curve or bulge in a foundation wall – specially one made of concrete block? If yes, then prepare for some repairs soon. Bowed walls will cause water infiltration and may weaken the entire foundation but can normally be fixed with steel bracing.

Water Lines on Basement Windows

Basement windows are supposed to let in light and air. Signs of retained water means the window well drain is either severely clogged or missing.

Water Marks on Walls

If you see stains from water that are running down basement walls, water has entered the basement due to exterior sources of infiltration or grading problems. If it occurred once, it’ll likely to occur again.

These signs will help make you a smarter home buyer if you consider them when making a final decision on buying your new home. Don’t let these signs scare you away, though, because all these problems can be permanently fixed by a reputable company dealing with home waterproofing Hamilton.

How To Know Its Time For Interior Basement Waterproofing

If you have a wet basement and you are confused between exterior basement waterproofing and interior basement waterproofing Hamilton. Have a look at the these signs of an exterior problem.

Signs of Foundation Problem

Wet Basement Walls

If you see wet basement walls that are wet higher up, there are chances that your foundation is worn off and dampness is seeping into the walls. Most basement walls have damp proofing system that includes a thin coat of concrete over the blocks and then a tar. It is meant to protect the basement walls from dampness. But, over time, the tar tends to breakdown and dissolve in the wet soil outside. Which is why, only a thin coating of concrete is left on the wall. Eventually, the coating will crack and let the water go into the basement walls, which causes all the signs you see inside.

Chronic Pain Failure

Discoloration, mold growing, bubbling are some potential signs that the foundation wall is holding dampness. This dampness is the major reason behind the failure of the paint. Basement waterproofing paint such as dry-lock will not be able to stop such conditions from occurring.

Solutions For Wet Basement

Full excavation of the walls, repair of all cracks, re-coating of the wall and installation of a waterproof membrane are the best possible solutions of wet basement. This membrane with refrain water from penetrating into the wall. New exterior footer drains will efficiently discharge the water away from the foundation keeping it dry throughout.

Interior basement waterproofing systems are ideal options for ground water issues. If you see dry basement walls, but water draining through the base of the wall at the floor seam, this might be the possible sign of ground water buildup that couldn’t find an outlet to escape. Due to prolonged heavy rains or snow melts, ground water build up around the basement and you will see it at the seams. Often this condition continues till the water is working its way down after the rain stops.

Working of Interior Basement Waterproofing Systems

Interior basement waterproofing systems include an interior sub floor footer drain that is meant to direct away the water from your foundation. This will lower the water level and prevent it from leaking inside your foundation. Be cautious of systems that install drains on top of the footer as these are difficult to be installed with a pitch for drainage. They depend on water building up and look for a definite level to efficiently push its way towards to a drain or sump pump location.
