Get A Free Waterproofing Inspection

Your Home's Health Starts From the Ground Up

Water in your basement doesn’t stay there. Heavy rain, spring thaws, and rising groundwater can send moisture toward your foundation and into your home. Once inside, that moisture can linger — creating conditions for mold, damaging wood, and affecting the air your family breathes upstairs. A properly sized sump pump helps collect and remove groundwater before it can build up in your basement, keeping your home drier and better protected.

Why New Jersey chooses RAdata

NJ Basement Waterproofing Experts

Free Professional Inspection

A licensed and certified team means a thorough assessement and fast and efficient install.

Installed in as Little as One Day

Most New Jersey waterproofing projects are completed in a single day, depending on the size and scope of your project.

A Dry Foundation

A whole-basement dehumidifier holds humidity below 60% so mold and musty odors never get the conditions they need to take hold.

Full Sump Pump System with Battery Backup

After install, we load-test the pump, confirm the backup kicks in, & verify humidity is holding below 60% — the point where mold and rot take hold.

 Trustindex verifies that the original source of the review is Google. We had a great experience with Protect Environmental / RAdata. It was easy to get an estimate for our radon system, and Charif did quick, clean work installing it. Rocco finished the job by hooking up the electrical and made sure our breaker was labeled and we knew how to ensure the fan was working properly. System runs quiet and is unobtrusive inside and outside. Would definitely recommend this crew.

 Trustindex verifies that the original source of the review is Google. Every individual I interacted with was fantastic, from the office personnel, installer and testers. All appointments are confirmed via text and adhered to. You’re also notified via GPS Tracking when they’re on the way which is especially helpful when service involves an empty house on the market. Highly recommended.
