"Job was promised to be less than two days. The crew arrived at the time agreed on and was thorough, covered walls not affected by the work and were finished by the end of the morning. I will recommend AA Action to anyone in need to basement waterproofing, crawl space improvements and related items."

"Jeff came to give us cost estimate for fixing our basement leaking issue. He was one of most knowledgeable professional I ever meet during my initial move in to new house. He explained why it is leaking and what we can do about it in very detailed logical explanation with clear diagrams to assist my understanding. Jeff said to fix these issues if it still leaks than come back for further assessment. It was great help, and I can really work on source of this problem now. I will never use any other waterproofing company other than All Aspects Waterproofing, LLC."

"

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.

"Juan and his team did another great job for us. They performed this necessary repair in a timely fashion and were very professional. They had to coordinate their work with the basement waterproofing people and they have no problem doing that. We intend on using this company for several other repairs in the future, and I would strongly recommend them!"

Basement Waterproofing questions, answered by experts

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

The purpose of soffits is to circulate air, so a blocked soffit means the air in your attic becomes stagnant. This can lead to a number of problems, mostly moisture-related, that can cause damage to your health and your home. The good news is that unclogging soffits is relatively straightforward, and if your attic is easy to access, an easy DIY project.

Proper drainage is the only way to ensure that your crawl space stays dry. Depending on your property and the extent of your issue, you might need to consider a gutter system, a French drain, or sump pumps to avoid and handle water and moisture under your home. Dehumidifiers can also help to prevent moisture from accumulating if you have a high-humidity environment.

The most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged.

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.
