"I was impressed with this company from The first time they came out to quote the job because I was immediately handed a folder that contained their license and proof of insurance. I accepted the bid and, while we got off to a few false starts, the work was completed in April 2025. The crew that came out was professional, efficient, and very respectful of my property. The chimney and tuck point repair work that they completed was professionally done and you could tell that they took great pride in Their work from the pictures that they showed me of the completed job.

"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."

"I was skeptical about using Angi because of a prior experience, but I am glad that I gave them a second chance. I got quotes from several companies, but Howard was so enthusiastic and informative that I opted to go with him and boy I was NOT disappointed!!! My master bathroom was transformed from a 1962 boring en-suite bathroom into a beautiful euro style bathroom. He was ALWAYS available for even the most inane questions and his crew is absolutely FANTASTIC! I was so pleased that we took out a HELOC loan to get the second bathroom done. I figured it would be nice because of what had been done with bedroom-WRONG! They surpassed our expectations. Sam, Marcus, and Larry are PHENOMENAL workmen. I could not believe that the second bathroom was even prettier than the bedroom bath. The recommendations that were given were right on point. I can not express my deepest gratitude for the professionalism, integrity and friendliness of his staff. Howard Emmer and staff are GREAT, you will not be disappointed!!!!"

The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed. If your basement is already outfitted with electrical and plumbing, expect the cost to fall on the lower end.
For example, the drywall cost for this project averages around $1,750, but other features, like hiring a plumber, cost between $45 and $200 per hour.
The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing.
If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms.
Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.
Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.
The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in.
If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
