"Basement Waterproofing Nationwide did excellent work in a timely and proffessional manner for a reasonable and appropriate fee. They said they would complete the work in 1-2 days and were done in one day. They were very careful and left things neater than they were before they came. We have used them before with great success and would use them again. So far, the problem we had, water in our basement, has not recurred, and our basement is bone dry. Tnank you Basement Waterproofing Nationwide."

"We are the 2nd owners of a 15 year old home. Don't know why the original owner/builder did not put a sump pump in the basement, as it would have been a cheaper option in the end. If you are building a new home with a basement, put a sump pump in, don't scrimp on what is a very valuable insurance policy. After looking at a handful of other companies to retrofit a sump pump in our cellar, we picked All Aspects Waterproofing, LLC. They did a great job! Very high quality work, and outstanding service. They did a great job! We enthusiastically recommend All Aspects Waterproofing to any homeowner!"

"I hired Humberto and company to do some work to my back walk-up; including structure repair, adding a step, burying a pipe for the sump pump and adding some height from the front step plus a railing. Adding waterproofing and concrete surface protection. Humberto carefully explained every suggestion. Always communicated any delay due to weather. He immediately and completely answered questions and concerns. The sub-contractors hired were also professional, punctual, hardworking. Not only on time, but the project was also completed early beyond expectations."

"Exceeded my expectation with waterproofing my entire basement + window wells. These guys are the real deal! I worked with Rob and I was educated and all my concerns were addressed. They do it right by you, the contract missed a window well and they were able to addressed that without having to go through a whole new quote/contract. Helped move some furniture around and left the place clean."

This company and crew is very impressive.  Here's a little background info.  Our property required a lot of help due to rainwater and a broken clay pipe (50 years old).  The house sits on the side of a hill.  When it rains, the water comes straight to the length of the whole house.  The previous owner had installed a "point" drain system which was useless.  They also installed a sprinkler system surrounding the whole property which works nicely for the planting beds. 


When David and Grant came out to the house for an initial consultation, I was very concerned about the disruption of current drains, the sprinkler system, and the shrubs.  First, while walking around the property, they were able to talk me through their process and reassure me that it could be done.  I never felt rushed, and they were patient with all my questions.


Second, Grant gave me an itemized price list for my property, so I could see where the money would be going.  I wasn't sure if I could afford it all at the same time.  The scope of work was major, but he was able to break it down into stages.  Through more emailing with Grant, another visit to the property, and other Angie List contractors coming out, I choose Drainage and Erosion to do the whole scope of work.  Their winter pricing and customers service sealed the deal.


Here's a list of the work done:  Excavating along the length of the house and creating two 30' French drains which flow into 6" pipes extending all the way to the curb (under sidewalk) on both sides of house (95'), Extending and connecting 3 downspouts on right hand side of house into a 6" pipe, Adding 3 drain cleanouts, Capping the 50 year old clay pipe that broke, Installing new sub pump piping and connecting into drainage pipes, Waterproofing wall/slab of foundation on Sunroom and two basement walls, Sealing cracks in walls, Installing 3 new window wells, Restoring grade for drainage, Removing all debris including shrubs not wanted, Transplanting two trees, The promise that our sprinkler system will be working in spring when it's turned on or they'll come out and fix it.


The actual job took only two days as contracted.  Grant came out the morning work began to answer questions and make introductions.  The crew of 11 men were hard working (9am-7pm) and also answered my questions.  All of this work was done by hand digging which allowed them to carefully move my sprinkler system and maneuver around the other piping.  When they were done, they seamed the grass back beautifully.  You couldn't tell what had been done unless you looked very closely.  Also the drainage holes in the cemented curb look as though they have been there forever.  We have 4 holes on the right and 3 on the left.


I highly recommend this company.

"Wendell and his son did a great job in repairing my basement wall which has been leaking water whenever a storm came in. Wendell provided a lot of information while setting up the appointment and diagnosing the issue. He offered multiple ways of dealing with it, but provided his own professional input on the best way rather than sell me on the most expensive option. He gave upfront honest pricing as well. Quality of work was great and they were fast and efficient in getting the job done. I would recommend Tru Integrity to anyone going through a similar issue of water getting into their basements."

Basement Waterproofing FAQs, answered by experts

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.

Covering the dirt floor in your crawl space with a vapor barrier helps insulate the space and improve the air quality in your home. It protects your crawl space from pest infestations, excess moisture, and mold growth. It also makes the crawl space less dusty, which means there’s a lower chance of dust mites breeding and causing allergic reactions in your home.

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

Overwatering can cause issues like water pooling and drainage problems. To prevent overwatering, monitor your soil levels on a regular basis and change your watering schedule as necessary.
