"Francisco has to be the best service contractor of any trade. Very HONEST, responsive and great quality work. We had several other basement waterproof system contractors out, and all were clueless or gave inaccurate information. Francisco's knowledge and expertise was impressive. Now, after several months and heavy rains, the basement remains perfectly dry. We called Francisco back for some minor cosmetic sealing, and he responded perfectly again, on a weekend day. You won't regret calling Francisco"

"I will start by saying that the work they did waterproofing our basement looks good, and I am hopeful that it has fixed our problem. We've had a good bit of rain recently, and so far, so good. That, of course, is the most important thing. That said, I chose this company, even though they were on the high range of the quotes I received, because I did not mind paying more for a professional experience and great customer service. I was disappointed with this aspect of the experience. The day they were scheduled to begin they never showed up, and I ended up calling them three times that day. The woman in the office was responsive, but she said that they did not know where they were. The next scheduled appointment was for the morning, and they did not end up coming until 2pm, again without any communication. Both instances were due to car issues, but a phone call to keep me updated would have been appreciated to allow me to better plan my day. When they did start the work the crew leader was friendly and appeared to know what he was doing, but he offered little information about the job unless I asked. Prior to the work being done, I also had to keep after the sales representative to put their warranty in writing. Twice he promised to email it to me, and only after contacting him a third time did he send it through. If I had not paid so much (over $11,000) I would have given them another star, but at this price point my expectations were high."

"58 foundations came to do waterproofing for my crawl space. The crew was prompt, very professional, and did a fantastic job. They accidently cut an electrical line that no one knew was there...and the service manager insisted on paying for repair...which occurred that afternoon. I was so impressed with their demeanor and their professionalism. They left my crawl space clean and neat. I was very glad I had hired them. I highly recommend this company."

"Josh and his crew were here at the agreed time and worked daily until the job was complete. Josh is very efficient and knows how to seal and protect the crawl space. I had previously used a pest control company to do the work but just ended up wasting a lot of money as the job was not done correctly. Josh is honest and dependable and I could not be happier with the work performed. I would recommend Sedona Waterproofing Solutions to anyone who needs it. I just regret not using them first."

I was extremely pleased with All Dry.  They gave me many options to fix my flooding basement problem without any high pressure sales techniques.  The crew did an awesome job and were very courteous.  I made a few changes as the install progressed and they handled everything with a smile.

There are a few companies that do the same type work and I have used 2 of them.  I would not hesitate to recommend All Dry.

"They did a good job on sealing up the basement. The french drain was a bit of a challenge. My car port was still flooding after a good steady rain. When they came back to fix, they removed some nice gravel that they installed originally and dug a little deeper and put in some stuff that was butt ugly. I didn't make a big deal of it because ultimately what I wanted was the flooding fixed. Getting them back to fix the problem took weeks. They often didn't return phone calls. The main guy said he had come out to look, but he didn't bother to tell me. The second time didn't fix it either. They finally came out a third time to work on the french drain after many phone calls and most of them not returned. I was told their answering service wasn't working a few times. Internet problems or something. But that went on for weeks. They finally sent someone out and they brought the drain further out from the edge of the car port. (The original problem they said was they couldn't dig any deeper because the edge of the carport had cement that was beyond the edge. My thought, they should have moved it back the first time when they realized this. The description of the ditch on estimate was it would be 12 to 18 inches deep. It was nothing close to this. I tried to point this out, they sort of ignored me. This whole miscalculation really wasn't my problem.)  They pulled ditch out on the other side of flower bed and made deeper, they put the crappy looking rock back and told me if it didn't work this time they couldn't do anything else. They pointed out how the hill on the side, (They put the drain in the front.) was so sloped that rain water was likely coming from there. Luckily this drain mostly fixed the problem. I felt they completely misjudged the drain situation. They bid low and that was tied up with some other work. So I can understand how their profit was trickling away. However; the way they handled the whole thing was unprofessional and careless. Due to this I decided I would probably not use them again. If you hire them to do their specialty, crawl space sealing, treatment and remedy, you may be happy with them. Just know you may have to deal with some issues around getting them to call back, etc.

Basement Waterproofing questions, answered by experts

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.

Home improvement grants are available for various groups, including individuals with very low-income housing, elderly people, older adults, and veterans. These grants can cover a range of needs, from accessibility modifications to addressing critical issues that may affect a resident's health or safety.

Below-ground shelters are the best in terms of durability, but there is a risk of flooding and obstruction. Modern technology and rigorous construction requirements make above-ground shelters a better option for accessibility, safety, and, usually, your budget. They may not have the same aesthetic appeal, but many of their features make above-ground shelters a better option. 

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.
