"It went well. They are being professional in their follow-up as they are trying to have us install an expensive basement drainage/pumping system. We haven't decided yet, as it will be part of our basement gut/rehab project."

"I had a wonderful experience with Delfino construction. They have completely transformed my house and property with a new drainage system and sump pump rendering my basement to be DRY! Also a new septic tank and leech field along with beautiful rock walls and U shaped driveway. The knowledge and attention to detail made our whole experience very comforting we couldn’t be happier with the turnout. Thankyou so much!"

"I was very pleased with the job they did. They resolved the water problem I had I my basement. They were very professional. The owner spent quite a lot of time initially determining where the water was coming from and then with his crew resolved the problem. I highly recommend this company."

"Dave was extremely helpful and super nice (and patient). We had some delays in our overall project and he continue to connect with me via phone and check in. The work in the basement was done quickly and neatly. I am so impressed with the Watchman team from Doreen in the office, Dave and the person who did the installation. You will not be disappointed with Watchman!!!"

"I've come across some very unprofessional contractors. I would say 90% of the contractors I have dealt during the remodeling of my home never called back or looked at my job and never returned an estimate as promised. The good news? ALL PRO Waterproofing isn't one of those companies. They were AMAZING. They sent someone to give me an estimate immediately - they called quickly to conform the install and they always showed up on time and ready to go. ** I would have given them 5 stars, but I found the price a little too high - but other than that - if you need basement waterproofing done right, don't waste your time with anyone else and call A"

Basement Waterproofing questions, answered by experts

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.

Generally, moisture barrier padding costs $0.75 to $1.50 per square foot, varying by brand and mix. That’s a lot more than standard padding, which runs $0.25 to $0.90 per square foot. The price difference between these two options might seem steep, but think of it as insurance against future carpet replacement costs and subfloor damage. If you have pets or kids, that extra investment in high-risk areas like your living room often pays off.

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

No, you don’t want your crawl space to be wet because water and even moisture in the air under your home can attract insects and rodents, decrease your indoor air quality, increase your energy bills, promote mold growth, and even lead to structural damage. If you notice any signs of water or humidity in your crawl space, you should get the issues addressed immediately by contacting a professional. They can remove moisture and will know how to waterproof your basement to prevent ongoing problems.
