"Excellent all around experience!!!!!!!! After a series of storms and gradual water soaking our basement carpet several times, I finally called Waterproofing One in April, 2017 after seeing their ad several times on our St. Basil's church bulletin. I spoke initially with the owner-Joe who was helpful and he dispatched Dave Cook who came over within an hour. Dave Cook has been in this business and related utility engineering previously for over 30 years and really knows his stuff. Dave was extremely thorough, spending time in the basement, looking at some pictures I took of the damage and spent a considerable amount of time walking around the exterior of my property and reviewing the landscaping where most problems start. Dave wrote up a report of what work was needed including extending downspouts, recommending we have our contractor add a louvered door at the top of the steps for aeration (a great idea given no windows in basement) , waterproofing the well water closet walls, spraying impacted area for potential mold, and installing a new French drain and sump-pump system with battery backup. Gene and his crew then came over on May 17, 2018 and performed the construction and installation work and did a great job. Those guys worked extremely hard in what is inherently a muddy line of work and were very courteous, professional and left the basement very clean. Gene took extra time to show us exactly what they were doing as they drilled holes into the lower cinder block walls, laying of the perforated pipe and some of the damp mold on the wooded studs he extracted at the impacted area. We paid exactly what Dave originally quoted! Dave Cook came back checked on things and made some other recommendations including adding stones around the foundation outside and in holes to avoid soil erosion and soften the acceleration of rain water into the ground. Once the work was finished and our carpenter redid the walls and painting, We had subsequently refinished the basement with high end vapor/mold resistant padding from Mohawk and a quality polyester carpet. 15 months later and here we are on September 30, 2019 after 50+ rain storms since installation and NO WATER nor Mold issues in the basement!!! We are really enjoying our basement again thanks to WATERPROOFING ONE!!!! 5-STARS!!!!!!!!"

"Scott Graham and his crew were extremely easy to work with. The work crew was courteous to me and to each other - very professional. Everyone on the crew got along. They were neat - the spaces where they worked were cleaner when they left than before they started. Most important to all, the drains and pumps they installed solved my wet basement problem. I highly recommend AWS."

"The team arrived on time to do extensive work on my basement floor and walls and outside underground drainage issues. They worked tirelessly all day to remove old concrete, lay a new pipe system, pour new concrete, install sump pump, and seals. They prepped the walls and sealed and painted with Loxon paint. Radon seals were included in the redone areas. The outside work included installation of a new underground drainage pipe with pop up exit drain. A rubber membrane was installed behind the house siding. We?ve had several days of heavy rain since the waterproofing work was completed and the basement floor and walls have remained dry. We recommend Basement Gurus to other homeowners experiencing waterproofing problems for dependable and satisfying solutions."

"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."

"We had numerous issues with water in our basement in the 5 years we owned our home, it was not an easy fix and we received numerous ideas and quotes. The rep from Worthington came out and was amazing, did not try and up sell us, and identified and fixed every problem. Worthington was not the cheapest firm we spoke with but would you really want the guy with the lowest price for a job like this? We would recommend this company emphatically."

Basement Waterproofing questions, answered by experts

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.

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?

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.
