"They are great to work with. Communication was superior. They stand by their work. A few years ago I had waterproofing done in my basement and this time they spray foamed the cavities of the basement too. Both times they did awesome work and cleaned up too! I highly recommend this company!"

"Thrasher did a good job on the basement foundation and installation of new sump pump. A little pricey. Workers were prompt, courteous and cleaned up when done."

"Brian arrived with his worker, assessed the issues and presented a couple of options to work with. The work was done efficiently in a few hours and I no longer have any leaks in my basement. I was very impressed with the work and the way he goes about his business. There was only one area that we could not figure out if it was leaking from the foundation or if it was coming from above. We agreed to test it the next rain fall and have him come back to fix that section. Unfortunately it didn't rain again until spring and when it did I was unable to reach him. I think this company is no longer in business or at least that is the impression I get because all of his contact information is no longer in service. It's too bad because I really like the work he did for the price he quoted.

"Basement Seepage Solutions was my fifth quote. I almost canceled because I was sick of getting quotes and all the big companies charge about the same $70-90 per foot of drain tiles. Matthew's company beat these quotes hands down. He charges $50 a foot plus $10 off a foot for Angies list members (a savings of $1000 for me.). This company beat the next lowest quote by $3,600 so this was a no brainer. Matthew's company did excellent work. They were on time and professional and communicated with me the entire time. Also, Matt is on site during the process and is not just a sales man who comes for a quote then sends out a crew. The job took two days mainly due to the Villages inspection schedule. But I think this is preferable over the big companies that want to do it all in one day but are in your house from 8-8. Highly recommend if you need any sort of basement work done"

"We have just had AOM complete work on our home. If you are on the fence about using this company, I hope this review helps. The interior of our home had not been painted since it was built (about 2003). It still had the flat contractors paint and some areas were looking decidedly worse for wear.Being pregnant with a toddler on the loose, we decided not to attempt the painting ourselves. I commenced obtaining quotes. Generall,y when having work of any kind done on our home or appliances, I prefer to go with a company that has been recommended to us by friends or family we trust. So we had a number of companies from around the local area come to give us quotes. However, I spotted AOM on Angie's List and was intrigued by their offers and more importantly, the reviews people gave them.I decided to call them for a quote. Well, they were super fast in getting back to me and David offered to come out the next day to provide a quote. After a walk through and explanation of what we needed, he was able to quote me on the spot.We had a relatively tight schedule to get the painting done. We decided to have it done whilst we were away overseas. Certain past experiences have left me largely mistrustful of giving my home over to anyone while I am away, but after chatting with David and Ashly, the owners of AOM, I felt confident that we were in good hands. We were leaving in less than a month and needed the work done by the time we got back. No pressure. Ashly and David were fantastic in fitting on with our schedule requests. Ashly was so great in helping us to decide on exact colors to match our general idea of a color scheme, coming over more than once to put up paint swatches in the different rooms in different areas so we would be able to tell how it would look regardless of time of day. I can't tell you how many color samples we tried before we made our final choices. My mother in law was gracious enough to offer to be on hand to help out with daily concerns, and the AOm team worked so well with her. She was completely impressed - not an easy feat with her! Before we left we had constant communication with Ashly, who even helped me choose paint scents.While we were away, we got regular updates, with pictures from AOm as well as an online work board so I would be completely in the loop with the work done/to be done. We returned the day before yesterday and LOVE the work they have done. We are so incredibly happy and impressed with the work they did. They did all our ceilings,our walls, fixed cracks and dents where needed,painted the walls and to my absolute delight, managed to get my dinged baseboards and door frames looking like new again.They also took care of the smaller details, like kindly replacing globes they saw had blown out. Today, David came by for a walk through to ensure we were happy with everything. There were a few minor things that he fixed right there on the spot. Needless to say, all their fantastic reviews are well deserved.They work hard, work smart, have integrity, and are so very accommodating to their customer's needs. That they are also trustworthy is a huge thing for me , and I suspect that anyone having work done in their home, whilst they might not be about at all times, will understand this. Give them a call - you will not be sorry. Oh, and their quote? A fraction of the cost we were quoted by the others. We intend on using them for all projects in the future."

"Good.  We called Patrick and he responded quick and came over next day and gave us an estimate.  He is very nice and professional.  Estimate was accurate. Fixed price was for labor and parts, wife did not agree and she wanted to take the Angies List discount on labor.  We would probably use Patrick again.  We do not have or forsee any plumbing problems in the near future."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Mendota, IL

Yes, crawl space encapsulation is a good investment. It improves your home's energy efficiency and air quality, boosting its value. With routine inspections and maintenance, encapsulation provides a long-lasting solution to moisture and pest issues. Regular check-ups protect your investment, enhance energy efficiency, and maintain your home's structural integrity. If your home is prone to pests or moisture seepage, encapsulating your crawl space is definitely worth it.

A vapor barrier is a thin sheet of plastic that prevents moisture from seeping into your crawl space, while insulation prevents unconditioned air from entering. Combining both insulation and a vapor barrier creates a dry, temperature-stable environment. Some insulation products serve both purposes, enhancing energy efficiency and protecting against moisture and temperature fluctuations.
