"The most important thing I can say about Atlantic Coast Waterproofing is meet with all other foundation experts first, then call Gary. Why? INSPECTION 1. He pointed out that my basement floor overlaid the footer at different heights based on where you are in basement. --No other specialist pointed this out, this detail is very important 2. He was able to point out previous homeowners put in "home made" system --No other specialist pointed this out, this detail is very important 3. He was able to answer my questions about exterior of house that might need attention to maximize keeping basement as dry as possible, while working in parallel with interior system 4. Professional, respectful, straight forward PROPOSAL 1. Informative 2. Best warranty in the industry. 3. Cost came in similar to other proposals that would not have been effective solution for my situation INSTALLATION - BASICS 01. Anytime Gary ran into a home specific challenge he was able to overcome and offer different solutions to correct 03. Any silly question I had was happily answered 04. Walked me through progress daily 05. Was able to adapt to inspector asking for a different proposed sump pump solution, this was no problem 06. Was able to re-assure me that removal of old shower was best interest when he found sub-par installation and mold! 07. The work was super clean in basement 08. Trench was a good 14 inches wide, dug to bottom of footer, with 4 inch pipe installed 09. Gary made sure to test each weep hole very carefully and re-drilled any hole with questionable drainage or mortar clogs 09. Final gravel, pipe and cement installation was executed flawlessly 10. Permit inspector raved about the good job Gary and his team had done and he passed inspection with flying colors INSTALLATION - ABOVE AND BEYOND 01. There was questionable broken shower drain pipe, he just fixed it, no problem 02. While preparing area around sump pump Gary went the extra mile to investigate what could be another bad "home made" plumbing solution. Turns out the previous owner did not connect sump pump outlet to main sewer line, leaving a visible gap, and essentially allowing sewer gases to escape! Gary then switched gears, put on his plumber hat, and had multiple solutions to correct problem. There was a nominal cost associated with it, but I was MORE THAN HAPPY to pay for properly fixing a very bad plumbing situation. 03. Gary's crew are also there to get it done right. When his crew arrived one member pointed out that cleanout to main sewer line was not up to code. This was not pressing concern, but once other plumbing problems were uncovered, they brought this up to code at cost of some new PVC pipe. Very nice. 04. Gary's final cleanup surprised me, in a good way. After seeing first hand the unavoidable mess this type of work can cause, Gary humbly said they do their best with final clean up. Well, when we did final inspection, the basement and exterior never looked better. Nice."

"This project went about as well as I could have hoped for. Their sales contact was very informative and took the time to explain how this process works. Their prices were on the lower end of the quotes I had received. All in about $7,000 to waterproof my entire basement. They were professional, timely, and communicative. I felt like I was in very good hands. One year later, my basement has not had a single leak. I may soon be hiring them again for another project. This company is solid! I highly recommend them."

Basement Waterproofing questions, answered by experts

Begin by confirming you have all required permits and consider Flint’s clay soil, which impacts moisture control and drainage solutions. Schedule utility marking before excavation and plan work between late spring and early fall to avoid weather delays. Choose contractors familiar with Flint’s older basements and local flood risks, and ensure all materials are rated for the region’s freeze-thaw cycles for long-lasting results.

Helpful?

In Flint, be cautious of contractors lacking insurance, local references, or a physical address. Watch for vague estimates, missing details about foundation drainage, or pressure to decide immediately. Avoid professionals who dismiss the challenges of Flint’s clay soil or offer generic solutions. If there’s no written contract, no mention of permits, or no warranty for waterproofing work, consider other options.

Helpful?

For Flint homeowners, a reliable seasonal inspection routine is key to effective basement waterproofing. In spring, inspect for new wall cracks and test your sump pump after snowmelt. Summer is ideal for monitoring indoor humidity and clearing downspouts. In fall, address foundation drainage and seal gaps before freezing temperatures. Winter requires checking for frost near basement walls and monitoring for frozen pipes, especially in older Flint homes.

Helpful?

In Flint, interior basement waterproofing projects like installing vapor barriers or sump pumps typically take 1-5 days. Exterior solutions, such as foundation drainage systems or French drains, may require 5-21 days, depending on weather and project complexity. Permit approvals and inspections can add extra time. Flint’s clay soil and the age of many homes can sometimes extend timelines, especially during wet or cold seasons.

Helpful?

Address urgent issues in your Flint basement—such as standing water, large foundation cracks, mold growth, or electrical hazards—right away. If you notice persistent dampness, sump pump problems, or hairline cracks, schedule repairs within 30-60 days, especially before winter. Minor seepage or cosmetic stains can usually wait until dry weather, but Flint’s freeze-thaw cycles make prompt attention to structural issues essential.
