"I had tight time constraints and Sundry Waterproofing delivered!
A previous plumber had dug 5-6 feet below the dirt line and made some holes in my foundation to fix a sewer drain issue.  Unfortunately, the plumber never finished the job and left me with several holes in my foundation and a pile of dirt in my driveway.  
Upon my call, Sundry came out the next day and gave a reasonable quote to fix this, as well as replace some insufficient vapor barriers in my crawl spaces.  I agreed and they were able to schedule the job quickly.
On service day, the work crew, headed by William, arrived on time and got to work.  The crew (especially William) was very professional and got the job done in about 3 hours.  
I thank William and his crew for a job well done, and Curt (the owner) for his flexibility.  I highly recommended these folks.

"They had to take out a portion of my front wall which was not planned on, and the conic quality of the concrete was not as good as I thought it should be they destroyed the brick wall that they said they would be able to save and I think they also damaged an additional plumbing line, which I’m going to have to have repaired But we did get the leaking stopped, which was the big part of the problem they had to dig up the entire front foundation down to the 8 foot footer and re-waterproof the wall put in a French drain system and a new drainage system for the gutter and a sump pump"

"The work was performed on time and as estimated. The scope of the work was appropriate to the presenting problem (unlike the proposals received from the larger waterproofing companies) and the estimate was a fraction of the price proposed by other companies. The estimator, Lupe, was responsive, and excellent at describing the work to be done and at answering questions. The work was completed in a timely manner, and the area was left neat and clean."

"Hugo was prompt and professional in coming out and giving us an estimate and an overview of what he was going to do. We were not sure if our problems were due to a leaky shower or if it was due to a foundation problem. Nevertheless we chose All-Pro Waterproofing to ensure we covered all our bases. It would have been good if we had an overview of what problems were or were not found once the project was completed. The crew who came to the house did an exemplary job of cleaning up and took care not to disturb the plants around the work area."

"Our basement got flooded in early January 2023 during a bad storm. We got estimates from 2 waterproofing companies. CGS Waterproofing sent a representative quickly to survey the damage and let us know what needed to be done. Nick seemed to be very knowledgeable and experienced in this type of work. An estimate from another company was considerably higher. After getting the 2nd estimate, we called the CGS rep. again (Nick) and asked him to clarify some things in his estimate. He came back out for a 2nd visit, and declined to take any compensation for the additional trip. The men who came to do the actual work were fast and efficient, did exactly what they said they would do, at the agreed-upon price, and they left no mess. We could not even tell that portions of our yard had been dug up, because they made it look like it had not been disturbed. Since then we have had several rain events and no water has even come close to our basement. I highly recommend this company."

Basement Waterproofing FAQs, answered by experts

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.

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.
