Acculevel is your foundation repair expert, serving Indiana, Illinois, Michigan, Kentucky, and Ohio with over 20 years of experience. Our repairs come with a lifetime warranty. Acculevel begins by evaluating your entire foundation system, checking your property for the signs and causes of foundation failure. From foundation & crawlspace repair to waterproofing & encapsulation systems, Acculevel can help you protect your home-- the most valuable investment you'll ever make.

"In drilling holes in our laundry room floor they drilled two holes in a hot water pipe. The repair work and expense related to this was greater than the cost of their work. No verbal or written mention was ever made about identifying the location of water pipes. I assumed (mistakenly) that they were professional enough to either ask me to have this done or be able to do it themselves. Their response to my complaint was to send me a copy of my contract reminding me that they are not responsible for "cosmetic" damage and that complaints must be settled through arbitration. "

"AVOID AT ALL COSTS!!! Here is a list so you can read everything we’ve been through with this company. Spent over $11,000 in 2020 to have interior drain tile and a landing drain connected to a new sump pump Had water enter through the doorway by the drain 3 times since 2020, with the most water coming inside September of 2022 Called Safeguard in September 2022. Safeguard refused to even check the system, sent us a quote for $1,800 more work to “fix us up” without even checking anything on our property Had a 3rd party company out to inspect the drain that Safeguard refused to check. Discovered they breached our contract and connected the drain to village stormwater tiling without our consent or the consent of the village. Have never received as much as an apology. Instead, Safeguard blamed us saying the drain was clogged with leaves, and that is why we flooded. This was disproved by Roto-Rooter. Update as of 3/3/2023 AVOID AT ALL COSTS!!!

The company refused to fix anything and did not respond to requests until I submitted a formal complaint on the BBB website exposing the breach of contract Have spent months (5) trying to come to an agreement we are comfortable with in order to have them out to fix the work. They do say they will repair the work for free, BUT… They tried to get us to waive their liability should the village fine us for the stormwater connection. There will be NO WARRANTY of this free work. So, if the concrete starts breaking a few months after the fix, they’re not liable. They claim they did not connect the drain incorrectly, and they are doing this fix to appease us (even though I have my contact that clearly states what was to be done, and a signed letter from the president stating that they did in fact do something else). As a result, we asked for a simple 1 year work and materials warranty just to ease our fears about something breaking in the future. Their response- WE WILL NOT ALTER THIS CONTRACT. Bob, John and Karen have been nothing but awful to work with. They are argumentative at best. The amount of times sarcasm and ALL CAPS have been used in emails by Karen, as well as the amount of times my husband has been screamed at over the phone or in person by Bob and John are immeasurable. As soon as you write them a check and they finish the work, they’re done. Even if they blatantly breach your contract (like with us), or the work is faulty, I believe they will not fix or stand by anything. They claim they have one of the strongest warranties in the business- I assure you this is a lie. If they do work and it never breaks, consider yourself lucky, because if something goes wrong they will not help you in any way shape or form to solve the problem, in my opinion. Instead, they will blame you as the customer and ignore you until you become too loud to ignore. Do yourself a favor, spend a little bit more money and go somewhere else that actually backs up their work and treats their consumers well. This is not that place. RUN AWAY.

Basement Waterproofing questions, answered by experts

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.

Yes, you can technically make a crawl space liveable, but the only way to do so is by converting it into a basement. While some crawl spaces are big enough to walk through and store large items, they lack appropriate insulation and space to be liveable.

Water damage to a foundation often starts as a slow leak or water vapor problem that worsens over the course of months or even years. The speed at which foundation leaks worsen depends on a few factors, including your climate and location, the soil composition around your home, the foundation drainage system you have in place, if any, and the type of foundation you have. Even if you have a minor issue that’s slow to develop, it’s best to have a professional address the issue immediately.

Yes, you can over dehumidify your house. While you may prefer a dryer climate inside, the elimination of too much moisture in the air can lead to an extremely dry environment that can affect those with respiratory and skin issues. Strike a balance between eliminating excess moisture without making your home feel like a desert. Most modern thermostats show the humidity levels for guidance.

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.
