"It is very convenient, and reasonably priced. The only thing that they could work on is the punctuality of the pick up times. The rest of the experience was satisfactory. My daughter has also used them. I would highly recommend this service."

"Ray and his team were incredibly professional, kind and courteous throughout all of the home projects. Their work on my basement foundation, installation of French drains and the rebuilding of an exterior wall were all phenomenal and at a very fair price. I highly recommend their services 10/10"

"The first step involved trenching the inside perimeter of the basement slab, which was relatively new and required substantial work with jack hammers (very dusty and noisy). The trench was about 18" wide and 18" deep to accommodate the perforated pipe and the surrounding material consisting of hard plastic "peanuts" to facilitate drainage. Workmen also installed corrugated plastic on the vertical wall surfaces so that should any water enter higher up on the wall it would be directed into the trench. The trench was then covered with a clear plastic vapor barrier, after which cement was floated over everything and leveled with the rest of the slab. NOTE: the trenching is very destructive and the workmen will remove any finished elements - baseboard, sheetrock, framing, carpet etc. - to access the walls and foundation. Be prepared to budget repair work on any already-finished areas once the work is done.
The team was invariably punctual, thoughtful and kept the work area clean. Charlie stopped by regularly to ensure the project was moving along as planned and helpful throughout. When finished, the crew cleaned up well and left the site in good shape, although it took some time finally to get rid of the dust. My only disappointment was that the backup batteries were left in their cases on the floor, when it seemed that they should have been up on a shelf away from harm.
The good news is that our basement has not seen any moisture since the system was installed. We've experienced some bad storms combining rain over frozen ground and snow and water clearly was getting through the foundation. We saw the pumps moving significant amounts of water out of the house and the system has been completely reliable. Finally we were able to finish the basement as we'd hoped because we're confident the drainage system is protecting the investment.

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.
