"I waited a few months before posting my review to test the finished product. All I can say is incredible from start to finish to performance! Jordan and Jim are two of the most honest people I have ever met. The estimate process went so smoothly. No pressure, no overselling and scare tactics I had with other large companies. Jordan listened and offered real solutions. In fact they turned out to be over $15K less than the next bidder. Jim who also owns the company and his crew showed up on time. Worked their butts off and explained exactly what and why they were doing certain things.Just another level of transparency. They put in french drains, concrete walls to support the compromised brick ones in the basement. Then two new sump pumps one is a no power required backup, a pump to remove the washing machine water into the sewer line instead of the sump pump. The also wrapped the basement, crawlspace, installed a new crawlspace door. All in two days! The house is so much nicer and dryer. My AC does not run as often, the basement is dry. We used to get water after every rain storm. We have had several heavy downpours and not one single drop of water! I highly recommend them. Fair and honest people!"

"Francisco has to be the best service contractor of any trade. Very HONEST, responsive and great quality work. We had several other basement waterproof system contractors out, and all were clueless or gave inaccurate information. Francisco's knowledge and expertise was impressive. Now, after several months and heavy rains, the basement remains perfectly dry. We called Francisco back for some minor cosmetic sealing, and he responded perfectly again, on a weekend day. You won't regret calling Francisco"

"I will start by saying that the work they did waterproofing our basement looks good, and I am hopeful that it has fixed our problem. We've had a good bit of rain recently, and so far, so good. That, of course, is the most important thing. That said, I chose this company, even though they were on the high range of the quotes I received, because I did not mind paying more for a professional experience and great customer service. I was disappointed with this aspect of the experience. The day they were scheduled to begin they never showed up, and I ended up calling them three times that day. The woman in the office was responsive, but she said that they did not know where they were. The next scheduled appointment was for the morning, and they did not end up coming until 2pm, again without any communication. Both instances were due to car issues, but a phone call to keep me updated would have been appreciated to allow me to better plan my day. When they did start the work the crew leader was friendly and appeared to know what he was doing, but he offered little information about the job unless I asked. Prior to the work being done, I also had to keep after the sales representative to put their warranty in writing. Twice he promised to email it to me, and only after contacting him a third time did he send it through. If I had not paid so much (over $11,000) I would have given them another star, but at this price point my expectations were high."

"I had my foundation and basement waterproofed from the inside by Groundworx. The first bit wasn’t good bc I got my appt cancelled and then the next appt no one showed up. So, by appt #3 I got Carlton. He was great. Super helpful, knowledgeable, etc. I purchased the services bc we really needed it asap as I had major mold growing in my basement from the previous owners negligence. I do feel like the price was too high but that’s a Groundworx issue. NOT a Carlton issue. I understand the rep doesn’t control the cost of services. For two days and waterproofing it was around 13-14k. It was extensive work but I did the demolition and removal myself to save $$. The work started and we had Von, Tim, Will and another gentleman. The guys were great. Beyond awesome. They explained so much and helped me with my silly questions. We really enjoyed them and they made the job site so clean it was like they were never there (except for my new pump and my ripped out basement haha 😂) they clearly know"

"I've worked with Donnie on several properties to evaluate structural issues, he's always been very professional and thorough with his inspections and identification of structural issues. Recently I had him perform a structural repair on one of my properties that had a tight deadline due to insurance and he got it done without an issue. I would recommend Donnie and Upstate Structural Repair for any structural repairs or consultation!"

Basement Waterproofing questions, answered by experts

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

The first step to preventing foundation cracks is to repair any current ones. When one crack forms, it becomes more likely that a second crack will follow. A few other tips include performing regular foundation checks, cleaning spouts and gutters, and installing exterior drains if needed. For those living in a hot and arid area, you should water your foundation every other day.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Brick is designed to absorb moisture, but it is also designed to let it evaporate as well. So in general, the goal shouldn’t necessarily be keeping moisture out but making sure it has the room to breathe. If you have excess moisture getting through your brick wall, it’s more likely that you have a crack or other issue at play that a typical sealant won’t fix. So, instead of investing in sealant, try repairing your brick wall instead.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.
