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

Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.

If you decide to fill the space around your home’s foundation with landscaping materials, it’s important to consider the aesthetic as well as technical factors like drainage and protection from pests and the elements. Materials such as gravel, rubber mulch, concrete, and brick masonry are all good options.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation.

Yes. Water can penetrate through a concrete foundation wall. This can happen whether or not you have cracks, as concrete is a porous material. You’ll want to take steps to waterproof your basement or crawl space.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.
