"I usually keep matters like this private, but after weeks of being ignored, I feel I have no choice. On July 26th, I was forced off the road by a driver in an Indiana Foundation Company vehicle (US DOT #1387693). The driver swerved into my lane, causing me to hit a curb and damage my car. I spoke with Pat Diehl, General Manager, who told me to email my information so their insurance could follow up. Despite multiple emails and phone calls, I’ve received no response at all. If this is how Indiana Foundation Company handles situations caused by their employees, it makes me question how they run their business and how they treat their customers. Accountability and communication should be the bare minimum. All I’ve asked for is a response. Jeffrey C."

We are a family owned and operated company that takes great pride in a job well done. We have been fixing foundations for three generations.

"This company repaired all wall cracks in my basement and installed a drain system on all walls of my basement. This company showed up when they were suppose to and completed the work on my basement in a timely matter. I had to contact this company to come back out after the work was done but come to find out, the problem we experienced was not due to any of the work this company had previously done however they still repaired the problem without charging us anymore money. Would definitely recommend this company to others."

Basement Waterproofing questions, answered by experts

In most climates, contractors recommend closing your crawl space vents in winter. Keeping them shut protects your crawl space from freezing temperatures, pests, and cool breezes that can lead to chilly floors in your home. However, it's often best to speak with a local crawl space team about your specific design and its relationship to the winter season.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

Having a trusted crawl space contractor is the key to great encapsulation. If you're not sure how to hire a crawl space pro, begin by asking your neighbors for referrals. Homes in your neighborhood will often have a similar foundation to your house, and personal recommendations are one of the best ways to find a contractor. Additionally, double-check that the contractor has experience with encapsulation as well as proof of their license and insurance.
