We moved into a new home where a deck was built by the builder on our second floor above our concrete patio. On top of this, the builder did NOT frame above the deck, so in the rainy months, we had no outside space since water would go right through the deck to our patio below. I contacted a...

Though a bit pricey I was very pleased with the results. The new pump doesn't rattle my plumbing when it goes off and everything now drains as it should without backing up into my basement. Have recommended Kirk Thompsen to my friends.

"This retaining wall was done during last April and it took a full week to complete. Even with some of the days having some rainy weather, the guys kept at it and did finish this wall well done. I had some weed prevent fabric put down on top of the back fill, and then I chose gravel which I like and have no grass to water and mow. So yes this project ended up with good function and looks, thanks."

Basement Waterproofing questions, answered by experts

You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair. These professionals will often be able to treat the symptoms of the issue as well as the underlying problem so that you don’t have ongoing damage. They’ll also often take preventative measures to stop the issue from recurring in the future.

Crawl spaces are prone to issues caused by excess humidity and improper ventilation, but that doesn’t mean you should avoid buying a house with a crawl space. A home that is encapsulated and well-maintained shouldn’t have any more issues than a slab or basement home.

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

Some basement waterproofing methods can actually cause your water or moisture problems to get worse, which is why it’s so important to call in a professional who knows how to solve your underlying issue and use the appropriate waterproofing methods. An example of this would be applying latex waterproofing paint to the insides of your basement walls without fixing the water issue outside. Doing so can trap moisture in the basement walls, which can promote mold growth, peeling paint, and even damaged concrete. However, when done by a professional, the only downside to basement waterproofing is the up-front cost.
