"Good work in general; our basement no longer sees water for over 3 years now, which is the most important thing. But there were some real issues: The biggest issue is that USW did not adhere to local electrical codes, and did not arrange for a final inspection of the project. So we didn't find out that it wasn't to code until years later, and now it's a big hassle and minor cost to fix and get the permits. Ask your local gov yourself what you need to do for permits and inspections; don't rely on USW! USW said they would seal any foundation cracks found along the way; they didn't do this until I bugged the warranty dept about it (but they did do it eventually). USW sent someone out for the "annual checkup"... over 2 years after the install. It's a good thing they (eventually) did, because they discovered the backup battery wasn't charging. Now I know to check this stuff better myself. Prices also vary wildly and are kind of negotiable (I'd give more detail but I'm out of space)"

"AVOID AT ALL COSTS!!! Here is a list so you can read everything we’ve been through with this company. Spent over $11,000 in 2020 to have interior drain tile and a landing drain connected to a new sump pump Had water enter through the doorway by the drain 3 times since 2020, with the most water coming inside September of 2022 Called Safeguard in September 2022. Safeguard refused to even check the system, sent us a quote for $1,800 more work to “fix us up” without even checking anything on our property Had a 3rd party company out to inspect the drain that Safeguard refused to check. Discovered they breached our contract and connected the drain to village stormwater tiling without our consent or the consent of the village. Have never received as much as an apology. Instead, Safeguard blamed us saying the drain was clogged with leaves, and that is why we flooded. This was disproved by Roto-Rooter. Update as of 3/3/2023 AVOID AT ALL COSTS!!!

The company refused to fix anything and did not respond to requests until I submitted a formal complaint on the BBB website exposing the breach of contract Have spent months (5) trying to come to an agreement we are comfortable with in order to have them out to fix the work. They do say they will repair the work for free, BUT… They tried to get us to waive their liability should the village fine us for the stormwater connection. There will be NO WARRANTY of this free work. So, if the concrete starts breaking a few months after the fix, they’re not liable. They claim they did not connect the drain incorrectly, and they are doing this fix to appease us (even though I have my contact that clearly states what was to be done, and a signed letter from the president stating that they did in fact do something else). As a result, we asked for a simple 1 year work and materials warranty just to ease our fears about something breaking in the future. Their response- WE WILL NOT ALTER THIS CONTRACT. Bob, John and Karen have been nothing but awful to work with. They are argumentative at best. The amount of times sarcasm and ALL CAPS have been used in emails by Karen, as well as the amount of times my husband has been screamed at over the phone or in person by Bob and John are immeasurable. As soon as you write them a check and they finish the work, they’re done. Even if they blatantly breach your contract (like with us), or the work is faulty, I believe they will not fix or stand by anything. They claim they have one of the strongest warranties in the business- I assure you this is a lie. If they do work and it never breaks, consider yourself lucky, because if something goes wrong they will not help you in any way shape or form to solve the problem, in my opinion. Instead, they will blame you as the customer and ignore you until you become too loud to ignore. Do yourself a favor, spend a little bit more money and go somewhere else that actually backs up their work and treats their consumers well. This is not that place. RUN AWAY.

"We are so impressed with Everseal. They installed a sump pump and interior drainage tiles in our basement in March of 2021. The job took only four days. The employees worked extremely hard to install the pump, interior drain tiles and window well drains. The young men, who removed debris from the basement in buckets and returned with fresh cement, literally ran in and out of the house to complete the job. They were amazing. They then brought their own hose to wash down any residue on our sidewalk and driveway. They took great care to keep the dirt and dust to a minimum. As they broke up the concrete floor, they used a powerful exhaust fan that vented to the outside through one of our basement windows. For additional protection, they wrapped the furnace with plastic sheets and hung plastic sheets around the basement enclosing the work area. They then made a tunnel with plastic from the basement door to the upstairs front door. Yes, there was dust that reached the upstairs. But, without their careful concern for our home, it could have been much worse. After the project was finished, we washed our walls upstairs and they were fine. The dust that reached the upstairs was easily cleaned.   They were price competitive and always went the extra mile to answer our questions.  A month after the installation, they returned to install a gasket and aluminum strips around the flange in the area where we do occasional woodworking. They did not charge for this service. And, they kept a vacuum operating to capture the dust while they were drilling the small holes in the concrete. The results look great. They also removed their shoes before entering our home and then wore booties to keep the dirt in the basement. Again, it is their attention to detail that sets them apart from others.  Everseal is a top notch company and deserves an A++ rating!"

Basement Waterproofing questions, answered by experts

You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair. These professionals will often be able to treat the symptoms of the issue as well as the underlying problem so that you don’t have ongoing damage. They’ll also often take preventative measures to stop the issue from recurring in the future.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.

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.

There are a few downsides to a wet room, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.
