"They came out & explained how they were going to resolve the drainage issue from our basement & lawn. We were surprised at the depth of work they had done to ensure that this issue was resolved for the new owners. They did as they said they would do per the estimate. These guys worked so hard & got rained on a good bit of the day, yet that didn't stop them from completing the job. They went above & beyond. It has been over a month now & we are very pleased to see no drainage issues. Thanks Waterproofing One for coming to our rescue! Dave & Lisa"

"We are currently happy with the basement waterproofing and remodeling that was completed! There were issues - most minor but we haven't anything to compare as this was the first-time having contractors complete basement work for us; and our home is almost 100 years old. They were flexible given unexpected issues that came about with the basement. The water proofing was done first and they did a great job. They were happy to review and resolve any remaining questions/concerns and/or issues. Jorge in the service dept. is professional, punctual and is a great representative and asset for this company."

"Basement Waterproofing Nationwide did excellent work in a timely and proffessional manner for a reasonable and appropriate fee. They said they would complete the work in 1-2 days and were done in one day. They were very careful and left things neater than they were before they came. We have used them before with great success and would use them again. So far, the problem we had, water in our basement, has not recurred, and our basement is bone dry. Tnank you Basement Waterproofing Nationwide."

"Completely Dry completed waterproofing of my basement and foundation repairs in September 2020. I also purchased a dehumidification system. This was a major expense and Iâ m glad I was able to get it done. My basement is finally a usable space. It looks and smells so much better. There is absolutely no sign of water inside. The sump is discharging into the yard perfectly. The unexpected outcome is a soggy yard. Who could imagine that so much water was coming in?! Completely Dry is now going to do a second job for me: install a dry well and run the sump discharge underground. Considering how satisfied I am with the first job, I have total confidence this work will be just as good."

Basement Waterproofing questions, answered by experts

When hiring basement waterproofing pros in Newark, prioritize contractors with proven experience handling local clay soils and seasonal flooding. Request at least three Newark-area references, check for insurance, and confirm they offer written warranties. Ensure they’re knowledgeable about Newark’s building codes and humid climate. Always ask for a detailed moisture assessment and be wary of unusually low bids or high-pressure sales tactics.

Helpful?

Begin by testing soil drainage and checking water table levels in Newark before starting your project. Schedule waterproofing during late summer or early fall when conditions are driest. Notify neighbors if excavation is planned and have underground utilities marked. Collect multiple quotes, arrange for timely material delivery, and document the basement’s condition before and after work. Set up a regular maintenance plan to handle Newark’s changing weather patterns.

Helpful?

For basement waterproofing in Newark, choose materials that handle heavy clay soils and fluctuating groundwater. Exterior solutions like polymer-modified asphalt membranes and bentonite clay panels offer strong moisture barriers. For interior protection, crystalline waterproofing compounds and epoxy injection systems are effective for block foundations. Pair these with a high-capacity sump pump, interior French drain, and a 6-mil vapor barrier to address Newark’s frequent rain and humidity.

Helpful?

Homeowners in Newark should keep a digital hygrometer and moisture meter to track basement humidity, especially during the rainy spring and fall. Have a wet/dry vacuum, flashlight, and measuring tape ready for quick inspections and cleanups. Stock hydraulic cement for patching small cracks, silicone caulk for sealing joints, and extra dehumidifier filters. A backup sump pump battery and a drain snake help manage Newark’s sudden storms and soil drainage issues.

Helpful?

In Newark, signs that basement waterproofing may need to be redone include recurring water seepage after heavy rain, persistent musty odors, or new efflorescence on walls. Watch for widening cracks, paint bubbling, or a sump pump running more often than usual. If your system is over a decade old or wasn’t designed for Newark’s soil, schedule a professional inspection for peace of mind.
