"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!!"

"We had used Johnson and Johnson last year to install a Sump Pump and drain tiles in our basement. After a very heavy rain, we decided we better have a Backup Sump Pump installed in case the power went out which usually happens during a rain storm. Johnson and Johnson installed the Backup Sump Pump very quickly. We highly recommend them."

"Our basement wall had settled over five inches. They piered the front basement wall and brought it back up to level. The basement wall was beyond repair. They cut a section of the back basement wall and demolished the entire back wall and poured me a new basement back wall. Great job guys!!!

"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."

"Mitchell was excellent from the moment we met with him to show him what needed done thru job completion. They arrived when they said they would, completed the repairs and new work in the time frame they contracted for. Even though it was freezing cold, they kept working! His staff were very professional, knowledgeable and courteous. The work site was cleaned up. They replaced a whole side of our house siding with new and used the old to repair several damaged areas. Added a new roof to the basement entrance and new fascia & soffit and added handrails & porch railing. Repaired the back porch tin roof. I would recommend them for home repairs! Great value & workmanship. We would definitely use them again."
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.
