"We recently had our basement waterproofed by the American A-1 Waterproofing Company, and I couldn't be happier with the job they did. From start to finish, the team at American A-1 Waterproofing was professional, knowledgeable, and dedicated to ensuring that my basement would be completely waterproof. First, the team came out to assess my basement and provide me with a detailed estimate of the work that needed to be done. They took the time to explain the process to me, answer my questions, and address any concerns I had. I felt like they really listened to my needs and customized their approach to fit my specific situation. Once the work began, the team was punctual, respectful, and efficient. They took great care to protect our home and belongings, and they kept us updated throughout the process. They worked quickly but thoroughly, and we were impressed by their attention to detail. The waterproofing work itself was top-notch. The team used high-quality materials and techniques to ensure that every nook and cranny of my basement was completely sealed and protected from water damage. They also installed 3 sump pump and created a French drain to further safeguard our home. A-1 did a great job waterproofing our flooded and leaking basement. They kept coming back as bigger rainstorms showed smaller leaks and waterproofed the inside and outside until stayed dry. Overall, I highly recommend American A-1 Waterproofing for anyone in need of basement waterproofing services. They are professional, knowledgeable, and dedicated to ensuring customer satisfaction. Thanks to their hard work, I now have a safe and dry basement that I can enjoy for years to come!"

Customers say: True professional

"For several years we have had a leak in our attic near our chimneys. After every wind driven storm water would collect in our strategically placed buckets. The leaks persisted despite a new roof and multiple attempts at waterproofing the chimneys. Antonio solved our problem. He demolished, rebuilt and waterproofed our chimneys from the roof line up. We were very impressed with his professionalism, knowledge and attention to detail and are happy to report that despite several heavy rain events we have had no water in the attic since the work was completed. Antonio's crew was punctual, courteous and hard working. We highly recommend Mr. Debenedetto and would not hesitate to use him for any masonry projects we might have in the future."

"I am not yet able to determine whether or not the expected results of the basement waterproofing work is satisfactory as I have not had a rainstorm or heavy rain since the basement waterproofing work was performed. I will, however, pay great accolades to Quality 1st customer service, especially to Kyle. I was troubled with the proposal for the job as certain aspects of the language would have left me at an unfair liability should something had gone wrong with the work. I explained this issue with Kyle who followed through until the proposal was acceptable to me. The work crew was exceptional in that they were punctual, worked quickly, neatly and were, without question, among the hardest workers ever to have done a construction project for me. The crew was headed by Wilver along with his guys - Manuel and Jose. Again, I will refrain from commenting on the expected results of the work performed until the appropriate circumstances occur. In summary, I would say that Quality 1st demonstrated A1 customer service and the crew that performed my basement work were hard workers with great attitude."

"Work was done to code (which was not by previous company prior to my purchase of home). In addition to chimney repairs they did some work to boiler and hot water connects in basement that were not done to code. I am very satisfied with the work done. I highly recommend them and would hire them again."

Basement Waterproofing questions, answered by experts

In perfect conditions—meaning, no overexposure to the elements without roofing material on top of it—an ice and water shield can last for decades. In fact, many come with a limited lifetime warranty because they should last for a long time. If, however, the membrane is exposed to the elements during building or if there is a delay in installing the roofing material, it might only last up to 180 days if exposed to the elements. The key is to make it a layer of protection and then protect that layer by installing the roofing.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

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.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

Yes, you can technically make a crawl space liveable, but the only way to do so is by converting it into a basement. While some crawl spaces are big enough to walk through and store large items, they lack appropriate insulation and space to be liveable.
