"This business was professional, communicative, and on time from my initial inquiry to when the job was performed. When I initially called, they were able to get someone out to provide a quote within 2 weeks and had me booked within another couple weeks. I was provided a quote online, and that's what I ended up paying. No fine print. Everything was completely transparent. William and another person came to do the actual sump pump installation. They were on time and finished a rather challenging installation (the pipe exit needed to be in a different room than the actual pump) within 4 hours or so. He explained everything to me clearly and was friendly, courteous, and professional. I would absolutely recommend these guys if you're looking for any kind of basement repair/waterproofing."

"Corey C of Basement Technologies performed our yearly maintenance inspection on our Basement Technologies sump pump, and did a fine job. He arrived within the expected timeframe, and provided us a detailed checklist of all items inspected. He also reviewed the operation of the alarm systems with us. He was friendly and courteous throughout."

"I found Adam here on homeadvisor.com and I could not be more satisfied! From start to finish he is a professional that knows what he's doing. He repaired an old concrete foundation, sealed the basement windows, dug out the exterior to make sure he completely sealed the cracks and even found an exposed electrical wire down in the basement and fixed that. I could not be more pleased!! His response with an estimate, quote, time to complete the job, everything was just right on. Very pleasant and extremely professional. I highly recommend ACO an excellent company to deal with. I would definitely hire them again anytime! Thank you!"

Basement Waterproofing questions, answered by experts

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

Brick is designed to absorb moisture, but it is also designed to let it evaporate as well. So in general, the goal shouldn’t necessarily be keeping moisture out but making sure it has the room to breathe. If you have excess moisture getting through your brick wall, it’s more likely that you have a crack or other issue at play that a typical sealant won’t fix. So, instead of investing in sealant, try repairing your brick wall instead.

In most climates, contractors recommend closing your crawl space vents in winter. Keeping them shut protects your crawl space from freezing temperatures, pests, and cool breezes that can lead to chilly floors in your home. However, it's often best to speak with a local crawl space team about your specific design and its relationship to the winter season.

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.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable.
