Four Leaf Restoration, LLC, has over 10 years of experience in the waterproofing and mold industries. We specialize in everything from mold remediation, to sump pump installation, to waterproofing your home. We do not believe that the same company should perform the mold test and abatement, because that is a conflict of interest, We only do what is necessary, not what is profitable. Call us today for a consultation on your project.

"I hired Four Leaf Restoration to install a sump pump system in my dirt floor crawlspace. Mike, the owner, is a consummate professional and very honest and straightforward in communications regarding what needs to be done. He gave me a thorough report and estimate following his inspection. For the work that had to be done, his pricing was very fair. Due to recent storms, he was already fully booked but sent his crew over to start working the following weekend. Those guys did an amazing job: removed all of the tar paper covering the dirt floor and all the insulation overhead so they could inspect thoroughly for any mold due to humidity and any moisture that might have occurred. They sprayed the entire crawlspace in case there was unseen mold, then followed up with a spray mold deterrent. The sump pump and drainage system were installed and the entire floor was covered with a heavy gauge plastic. All new insulation was also installed. The crew dug a french drain out in my yard for the sump pump drain and tied in downspouts on that side to fully divert water away from the house. At the end of each day, they cleaned everything up. They did an amazing job! The man who does my annual termite inspection said he has never been in a crawlspace that is that clean and that actually smells good. Mike also recommended a dehumidifier for the crawlspace for summer months (same one he uses in his home). While he doesn't sell them, he gave me a link to a website and came by to set it up after it arrived. You will not find a more honest or hardworking company than Mike's Four Leaf Restoration. I cannot say enough good things about them. He was referred to me by a co-worker and I am so grateful for that referral!! If have problems with water or mold remediation/restoration in your basement or crawlspace, do not hesitate to call Mike at Four Leaf Restoration."

Pierce came out to take a look and after talking to him, I was confident he had the expertise to do the work. To no surprise, he and his crew did a fantastic job.

Foundation, basement or crawlspace waterproofing / encapsulations FAQs

Cleaning your crawl space is a worthwhile investment for several important reasons. A properly maintained crawl space prevents structural damage by eliminating moisture that can deteriorate wood supports and metal components. It also significantly improves your home's indoor air quality by removing allergens like mold spores and pest droppings that can circulate through your living spaces. 

Additionally, a clean crawl space contributes to better energy efficiency by allowing proper insulation installation and reducing humidity levels that force your HVAC system to work harder.

Several warning signs indicate your crawl space needs professional attention. Look for musty odors throughout your home, unexplained increases in allergy symptoms, higher energy bills, visible pest activity, or moisture issues. 

Other indicators include sagging floors, warped wood, visible mold growth, standing water, or damaged insulation. If your crawl space hasn't been inspected in over a year, or if you've recently experienced flooding or severe weather, it's advisable to have professionals assess the space even without obvious symptoms.

Most crawl space cleaning projects take between one and three days to complete, depending on several factors. Simple debris removal in a small, relatively clean space might be finished in a single day. 

More involved projects that include mold remediation, water damage repair, or pest control require two to three days. For large crawl spaces or those with extensive contamination, the timeline might extend to a week, particularly if additional services like encapsulation are included in the project scope.

You can remain in your home during basic crawl space cleaning. However, if the project involves mold remediation or pest extermination with chemical treatments, temporary relocation might be recommended, especially for household members with respiratory conditions or chemical sensitivities. 

Professional cleaning companies use containment procedures to minimize the spread of dust and contaminants into living spaces, but some disruption is inevitable. Discuss your specific situation with your service provider to determine the best approach for your family's needs.
