"The technician that did the service, let me know specifically one thing that turned not to be possible. I would never known, because the issue was below the ground. He also gave me post sales advice to recommend to my A/C who would be installing a unit near the repair."

"Fast professional and friendly. Spot on when it came to the estimate all the way around. Job site was clean and looked better than it ever did before Buxton started the job. We would recommend Buxton waterproofing every time! Raymond Buxton is what I would call an honest hard working family man, he treats you like a family member! Kind of a Jack of all trades!!"

        •        Frank's team at Advanced Foundation Repair and Replacement identified that my cracked basement wall and fireplace foundation had settled 1 1/2" along one side of my home, and needed 12 piers installed to lift and stabilize the foundation to prevent further cracking.    Frank provided a competitive estimate for pier jacking, based on other pier jacking I had had done on a front porch and laundry room slab, but he used a far more sophisticated technology than the other company I had used in the past.
        •        They first removed a 560 sq foot cedar deck, then excavated with a Bobcat down to the base of the foundation wall.   The gentleman running the excavator operated with surgical precision, leaving a clean wall and trench for the next phase.   They preserved the shrubs I wanted saved, and the only ancillary damage was a pinched gas line for my bbq, which Frank had repaired immediately after the job was completed.   My wife was impressed that they salvaged the deck boards and reused them for roof joists on another project, and salvaged the old bricks from an underlying brick patio and provided them to another who needed a patio but could not afford bricks. 
        •       The pier jacking involved driving 12 heavy steel pipes down to the solid subground (not down to bedrock) using a hydraulic press, then using those same presses and hydraulic rams to lift the foundation of the home 1 1/2 inches when all of the pipes were in place.  They then bolted and welded the pipes to the lifting flanges, making the lift permanent, and cut off the excess pipe.  The team brought in a Bobcat front loader to backfill the excavation after putting a waterproof sealant on the outside of the exposed basement wall, again operating it with surgical precision.  
        •       Through the entire process, Frank and his team communicated what they were doing, and met the schedule that they had proposed.   The site was left very clean, with all of the debris removed and the area of the lawn that was covered with excavated debris was scraped clean and ready for reseeding. 
        •       Frank was very responsive to my questions throughout the process, and left me with no surprises.   I wholeheartedly recommend Advanced Foundation Repair and Replacement for any foundation work needed.

"I saw them in the neighborhood, so I got their details and they gave me an estimate. They were re-repairing a crack from 20 years ago. They did their work and cleaned up afterward. I waited until after 3 or 4 serious rain storms before this comment. The basement still dry. No seepage through the cracks. I should have called them a long time ago."

"Perma Jack of St Louis did a wonderful job waterproofing my basement. For years I struggled with the cleanup year after year, it only got worse. I had gotten 3 estimates from other companies but The Perma Jack system made the most sense and was the most affordable. I’m a single mother helping to put my son through school so my budget was limited. The Perma Jack system allowed me to waterproof my entire basement when the other companies wanted more money to only include half of the basement. We didn’t need to remove the drywall like the other estimates called for which added to the savings. The workers were very cordial and answered my questions along the way. Everyone I had contact with from the office staff, the system design specialist and the workers were very accommodating. I made the mistake of calling the office after hours and much to my surprise the owner Chris answered the phone, that was a WOW moment for me! I complimented everyone and thanked the owner for taking my call, I assured him I would be referring his company to all my friends and family members. I highly recommend Perma Jack. My basement is dry as a bone and I can now sleep with confidence when I hear the storms rolling in."

FAQs for basement waterproofing projects in Union, MO

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
