"Honestly, we cannot say enough good things about Drainage Pros. They are professional, competitively priced, trustworthy, and - most importantly - excellent at what they do.
We moved into a 1920s home with major drainage problems. Four of the six original underground drains that collected water from the downspouts were nonfunctional. Our home also sat low on the property, and when it rained water flowed across our driveway, over the patio, and into our basement by seeping over the foundation. It looked like a small river coming toward our home and disappearing underneath.
AJ responded quickly to our initial inquiry and met with us on site to discuss the project. He listened carefully to our observations while assessing the driveway, patio, and grounds before sending us a detailed proposal the next day. The proposal listed several different stages and options, which we continued to discuss with him at every step of the project. AJ was always very  knowledgeable, communicative, and professional, responding to our many questions and concerns thoroughly and patiently (even when we asked the same question multiple times). Ultimately, Drainage Pros stood by their original proposal, working within budget, and they even guaranteed their work (although we don?t expect we?ll be needing the guarantee).
They tore out and had the old driveway re-graded and repaved, installed a channel drain behind part of the home, and laid pvc pipe along the entire perimeter to collect water from all six downspouts. They ran the pipe under two bluestone patios and walkways, all of which they reset carefully. They connected the pipe to our main sewer line, which required six foot plus excavations. Lastly, they reseeded the lawn (which returned nicely), and basically restored the grounds to their original condition. The paving company they coordinated with was also excellent, and they worked hard at communicating with each other to ensure that the project was completed to our satisfaction.
Personally, what I most appreciated about working with Drainage Pros is that AJ did not trouble us with all of the things that could possibly go wrong while performing such a major job like excavating and tapping into the main sewer line. He simply assured us calmly and professionally that he and his team could do the job, and they did. Perfectly.
We had previously discussed the job with a completely different (and also highly rated) contractor who appeared flustered by our drainage issues and, after charging us >$1,000 for an assessment and cleaning, was unable to offer us a written proposal or estimate without further ?diagnostics?. Do not waste your time and money, like we did. Just hire Drainage Pros, and they will get the job done.
We now have absolutely NO DRAINAGE ISSUES and strangely even look forward to when it rains so we can see how beautifully the water flows down the driveway, into the drains, and away from the house. If you are on this site searching for a drainage specialist, perhaps you can appreciate this.

Basement Waterproofing FAQs, answered by experts

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

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.
