Anchored Walls techs, Zach and Kyle, came ready to work!!! They added 9 anchors to 2 of my basement walls to stabilize them. Those 2 men worked hard! I have attached 2 pictures, the first shows shovels over the holes so no one would fall in, and the finished yard. You cannot tell where the holes had been. Both men also added waterproofing to my basement floor. If Zach and Kyle are an example of what to expect when you hire Anchored Walls, then the company gets 5 stars from me. Great work Zach and Kyle !!! * * * * *

Lack of clean drop cloth to cover for the floors was the only problem. Every thing was great.

An addition at the rear of our house settled due to inadequate concrete footings. Anchored walls came and installed metal rods 12 to 15 feet deep in the ground to level and stabilize the room. Other contractors' approach was way more intrusive - removing windows and flooring to get access. Anchored Walls did all the work from outside.

The crew arrived at about 8:00 a.m. to stabilize my garage wall, which they thought would take about a half day. They ran into unexpected problems under my garage floor and although it was extremely warm, they continued and finished the job at 8 p.m. Even with that they had cleaned up before they left. They did a great job and I appreciated that they were willing to finish as I had arranged for another crew to come to build a deck in that area the next day. That is dedication. Thank you Anchored Walls! K.S.

Why You Need Crawl Space Repair

The need for encapsulation and insulation is recognized by Des Moines’ crawl space repair professionals at Anchored Walls. Water in your crawl space needs to be fixed as soon as possible. Failure to have your wet crawl space fixed right away may lead to a variety of problems for the rest of your home, including:

Potential damage to the structural integrity of your home - Homes in Iowa won’t pass an inspection, if there's water laying dormant in a crawl space, because of this.
The growth of mold and mildew - If you have standing water lingering in your home's crawl space, the moisture can lead to the proliferation of mold and mildew. Mold isn't only aesthetically unpleasing, it can also cause a number of health problems. Mold spores in the air of your home can cause respiratory issues, headaches, fevers, flu-like symptoms and a variety of other health concerns.
Infestation of mites and insects, such as cockroaches and termites - These unwanted pests tend to like living in dark, damp places, such as a wet crawl space. Bug infestation in your crawl space can lead to bug infestation throughout the rest of your home, as well.
Indoor air pollution - The Environmental Protection Agency (EPA) lists air pollution in the home as one of its top five environmental health risks. A wet crawl space is one very critical danger. Due to something known as the stacking effect, around half of the air you breath at home may actually come from underneath your home. This is due to the fact that warm air rises and escapes through any leaks found in your home. When your home's crawl space is damp, it is likely to be filled with dust, mold spores, allergens and soil gases, which will then be dispersed throughout your home.
