"Quackers was the 2nd vendor to review the problem. The first vendor proposed a much more expensive solution. Quacker's saw that I did not have a sump pump in my sump pit so they proposed that this be the first step to fix the problem which so far is working. He also advised me to run new drainage tile away from foundation near where the water entered the basement."

"Gary Kimberlin's team did a great job for us with a series of small projects which were too big for a handyman, but apparently too small for most contractors. Most of the general contractors we contacted through Angie's List never never got back to us, but Gary treated us as valued customers from the start. Gary himself contacted us to provide a bid, and his responsiveness was exceptional. He spent about an hour with us taking measurements and discussing what we wanted to accomplish. Maybe we could have found a cheaper bid out there somewhere, but we were pleased with the punctuality and quality of the work, so I don't regret a cent that we spent. We had a series of small tasks which Gary's team performed over a couple of days. They arrived and departed when they said they would. First, they installed roll insulation in the crawl space under our living room. Rather than stapling the insulation in place, they recommended a slightly more expensive hanging system which allows the insulation to be removed and then put back without damaging it. Since additional remodeling is always a possibility, we appreciated the foresight on this issue. Second, we had planned to install a skylight in the living room, but Gary suggested can lighting instead, and I'm glad he did. Any time you punch a hole in the roof, it could leak, no matter how well you seal the edges. Can lighting was less expensive and created no possibility of leaks. We weren't happy with the first set of can lights Gary's team installed. Without complaint, Gary's team uninstalled them and replaced them with lights that we could swivel to highlight our artwork on the wall. We appreciated the team's flexibility and good attitude about the change. Third, the most complex portion of the job was repairing a wall and floor that had been damaged with pet urine. Gary's team removed the damaged baseboard, cut away the damaged carpet and pad, repainted the wall, and installed a new baseboard. This left a hole in the carpet which we covered with a throw rug, which was the solution of our choice. The repairs to the wall are seamless -- you'd never know the work had been done. Gary didn't press us to replace the whole carpet, which we weren't ready to do because our beloved older pet was still with us. The solution worked -- the smell is gone, and we didn't spend more than we wanted to. We'll complete that remodel another day. Last but not least, Gary's team did a thorough job cleaning and repairing the gutters. Small sections of guttering had come loose, which they refastened to the roofline. The one part of the remodel that didn't go as I had hoped pertained to a roofing issue. We had a gap in the soffit panels under the eaves. We had been concerned that a squirrel could climb through the hole and nest under the roof. Gary's team assessed the roofline and said that the hole in the soffit didn't communicate through to the attic, as far as they could tell, so the squirrels couldn't use it as a gateway. Unfortunately, that conclusion turned out to be incorrect. Six months later, we had to pay a wildlife control company to get squirrels out of our attic. The animal control team determined that the entry point was the hole in the soffit and installed a sheet metal cover for it. While the squirrel removal and roof repair were expensive, I don't fault Gary's team for mis-diagnosing the issue. Two other contractors/handymen had previously looked at the same problem and reached the same conclusion as Gary did, so obviously it was tricky. (We had had squirrels under the roof in a previous home, so I was concerned about this issue.) We look forward to work with Gary Kimberlin Construction again on a future remodel."

"Our experience with Atlas Foundation Solutions, LLC was excellent. Their staff was very professional, prompt and courteous. Their technician, Jacob was very knowledgeable and thorough. He found another crack under the deck that was covered in the basement with insulation and shelving, saving us another problem down the road. Great job, thank you!"

"Marlon Tuckpointing did a professional and seamless job on my chimney. I had missing mortar, discoloration, and a cracked and worn down chimney crown. Marlon came out right away and performed an assessment, made everything clear (including the price), and stayed in contact with me during the entire process. What impresses me most is their accuracy in workmanship, including the type/color match of mortar as well as the waterproofing work that protects my home from damage. When homes are 60+ years old, it is time to start thinking about the mortar and brick that holds your home together. While durable, over time, sacrificial mortar degrades and it's time to call in a professional to maintain the look and stability of your biggest asset. I am confident that you can trust Marlon Tuckpointing to do the job and am happy to recommend them."

"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!"

Basement Waterproofing FAQs, answered by experts

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.
