"The crew was absolutely amazing! Very impressed with how professional, polite, and personable they all were. The management and crews are top notch! Management answered all the questions I had, walked me through what steps they were going to take to get things done. Dustin was extremely thorough, knowledgable, and took time to explain the recommended systems. I will 100% be utilizing them in the future strictly based on the level of trust and quality he presented! His communication was fantastic, they always arrived on time. They were careful with the property, always cleaned up when they were done. I will absolutely hire them again to complete any future foundation/basement work and I will absolutely recommend this company without reservation or hesitation. They stand behind their work."

"Everything went as explained, diagramed, and promised by our System Design Specialist, Mr. Nicolas Hruska. We initially contacted just the top two Foundation Repair Experts listed on Angie's List because we can't afford to have our home repaired by anyone who lacks the proper credentials, staff, tools, training, techniques, supplies, 25 year transferrable warranty, and the hands on experience to deliver all services as promised. We are extremely pleased with the final results to take back our homes basement from poor workmanship done by the original builder and owner of our home back in 1979 We purchased the home in 2001 and unknown to us the foundation had been placed on top of clay based sub-soil which was an acceptable building practice back in 1979. Today's building codes prohibit this careless and costly practice of home site preparation for the homeowner. A word to the wise, do your home work first and then protect the biggest asset that most Americans have, their home. Respectfully, Kenny L. Hutcheson, CMSgt, USAF/USN, Ret. Indianola, Iowa"

"We are sure glad that we had Mike Schmidt replace our deck and retaining wall and place a stone walkway. We secured two bids from qualified contractors who both had a vision that we realized was theirs and not ours. We are glad we resisted the urgings to use fake composite.  Mike knew we preferred real cedar and he came up with a very stylish diagonal design with solid black railings. The store bought posts just did not match so Mike's crew hand cut cedar posts.  We sought a unique living space that was functional, inviting and personal. I wonder if he is a mind reader since he took to little direction yet crafted the perfect construction to meet our needs. We had a wet spring and we fully expected delay. Mike just did the things that can be done in the rain to keep the project on track to completion.  His crew did not allow the weather to delay progress.  

Mike also installed a new retaining wall that is so much more solid and aesthetically pleasing. We have a two story house with a walk out basement and the challenges of topography and existing doorways flustered the other bidders. Mike knew how to make it all flow with gorgeous flagstone steps. We've really seen nothing like it in a catalogue or magazine or on line. His creativity is paralleled with his attentiveness and genuine desire to please the customer. Knowing it was incomplete without tying the stones and deck into the driveway, he incorporated metal sculpturing, vines and mulch through a local contractor that seemed like a kindred spirit to Mike. 

Don't get us wrong  -- he does not take over. He listens and is responsive. Mike answers his telephone every time, is positive and cheerful and honest. This was however our project but sometimes you don't know quite what you want until someone enlightens you with the possibilities. That is Mike. He is approachable, is never offended with questions and is a good soul. 



We were very happy we were able to use Mike Schmidt and rate him an "A" in all categories.

Basement Waterproofing FAQs, answered by experts

Crawl space encapsulation typically lasts between 10 to 20 years. If you experience a catastrophic event, like a flood, or poorly encapsulate your space with low-quality materials, it may only last a decade. Otherwise, as long as you properly maintain your crawl space, a high-quality encapsulation can last more than 20 years.

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

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.

A crawl space is an area under the house that provides access to plumbing, electrical, heating ducts, and other HVAC units. Its purpose is to create a buffer between the ground and the living area, helping with ventilation, moisture control, and access for maintenance or repairs. Crawl spaces are most often seen in houses in North America which are built on concrete foundations versus other parts of the world where buildings are constructed differently.

While it’s possible to seal a foundation yourself, it’s not recommended, as it’s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a foundation repair professional near you to see what the job will cost.
