"I can't say enough good things about American A-1 Waterproofing. Roland and his team were amazing. I had originally opted to go with another contractor to install a French drain and sump pump, but after exposing the foundation, they got spooked and said they wouldn't perform the work. Roland came by and assured me his team could get the work done and they did not disappoint. Through the initial estimate, permitting, construction and final sign off, Roland and his team were communicative, prompt, clean, and extremely professional. It was an absolute pleasure to work with them!"

"The previous owner of our property used his French drain installation as a selling point, but shortly after we moved in we found water in the basement after a storm. It turned out that the "French drains" were a trench at the edges of the basement and a sump pump. The drains were not piped to the sump pump. We had Arid install real French drains with pipe to the sump pump well. Thus was in 2005 and we have not had any water in the basement since. Pat explained the job well and his team performed it quickly. They cleaned up well afterwards. The pump finally gave out last night (after almost 12 years). Arid is going to install new one on Friday."

"Very neat with their work in a messy job. Laid down protective flooring to prevent mud from being tracked through my house. Went from a basement with ankle deep water to a waterproof basement with no water in the basement even after tropical storm rains."

"We had French drains installed around the whole perimeter of the basement. They were very professional from start to finish. Very fair quote and to be honest the best we recieved. On the day of the project, Tony who had given the quote was there to walk us through everything and get it all going. Even Steve the owner came out and checked in with us. The crew was great. They answered any questions we had, were very hard working and left the house cleaner then they found it. Overall a great experience."

"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."

"Jersey Dry provided the best total solution for our basement water issues at the best price. They delivered everything as promised and went beyond. They even re-installed and repaired the basement sink by replacing worn piping and re-directed a gutter at no extra charge. They were extremely responsive to our inquiries and questions. They painted the walls and cleaned up very well. They ensured that we were totally satisfied by walking through the job before they left. They may be the best contractor that we have ever used."

Basement Waterproofing questions, answered by experts

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

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. 

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.
