"Mid-State Basement Systems came highly recommended by a good friend from Buffalo, NY and they did not disappoint. From start to finish they were very professional yet personable. Larry & Phil in the initial stages of the basement inspection and a reasonable quote. Silvino and his team who done the actual work was incredible, done with absolute excellence. They were here when they said they would be and finished the job a day ahead of schedule. I am thoroughly pleased with this company, first class. I highly recommend them if you need work done on your basement.******"

"I wish I had hired them first! I hired another company to fix my moving bowed and shearing basement walls. They were primarily a waterproofing company, but said they had the solutions to my issues. 3 months after they were complete, my walls cracked and shifted again. (Note, in the attached photos, the patchwork quilt on the walls was the OTHER company.) OBA fixed my issues the correct way. And they were great at every step. The work crew Caleb, Delontae, and Dylan were fast, efficient, and cleaned up when they were done. Caleb made sure to explain what was happening as they did the work and ask if I had questions. The work was thorough, and I feel good about it. And even better, they'll be out in 6 months to ensure everything is working as it should and make adjustments if needed."

"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!"

"t. The night before I flew to Arizona to graduate from doctoral school, I had 4 inches of water in my basement. One guy came out at 11: 00 p.m. and tried and tried for about 45 minutes to an hour to clear the pipe, but was not getting anywhere, so I told him to just come back in the morning.I left them an entrance into the house to work on it the next day and left for Arizona. They found that the city pipe to the main sewer collapsed. They called me (I was in O"Hare airport) and let me know that they faxed the city to tell the city to get out and check the pipe.  I called the city to get them to come out immediately (the city said they have 48 hours from the notification). The plumbers also called the city back because it was going to rain hard and I would have 8 inches of water in my basement. So, finally the city attorney called me and I told her that they had to get out there pronto or I would lose my furnace and hot water heater if any more water came in the basement. The attorney got the city crew out the next day. The plumbers checked on it through the whole ordeal and then the owner called me to let me know that the water was out of the basement and my basement was dry. I did the graduation walk with a smile instead of a worry that my basement would be completely flooded.
Another time, my shutoff valves burst and it was raining in my basement (yea really). They came out right away and took care of that before my basement was completely wet. They were kind when they told me that my main shut off valves had to be replaced soon as they too were about to break. Because my house is old, I appreciated them telling me about things that are about to happen before I wake up to yet another plumbing fiasco. (They told me the valves would probably be okay if I did not turn them, but not to wait too long as they were the main valves and then it would have to be shut off at the street.)
They go above and beyond what I would expect any service to do to resolve a plumbing problem I have read the other reviews. I really don't care what they use to light up whatever they have to see with, even if they ask me for my flashlight. I just want the problem fixed so it is really fixed. Everything they have fixed has not been a problem again at all. (Kitchen faucet, 2 sets of shut off valves, bathroom faucet, outside clean out, backup valve, sump pump. All these things have not been a problem at all. They are really kind when I call to ask basic questions.

Basement Waterproofing FAQs, answered by experts

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

If not properly maintained, an underground downspout may damage your home's foundation. A clogged downspout can back up, causing water to pool around the base of your home and seep into the foundation. Regular inspections and maintenance keep your downspout in good working order, preventing damage and protecting your home.
