"Dylan from Harts Services was prompt, professional and courteous... he scoped out three unfinished basement floor drains to determine why they weren't draining properly... he even invited me to observe the process which I did... Dylan was able to diagnose the problem and provide me with viable solutions and costs and within a short period of time emailed me that information to make an informed decision... quite pleased with the service and would/will not hesitate to engage Harts Services again"

"We had a foot of water in our crawl space after the snow and 6 in. of rain from the December 2021 storms. I had called several companies to come out to take a look and give quotes. Ethan from diversified was the 3rd quote we received. Ethan explained the issue, explained what they would do to remedy it, and answered all my questions. He sent me the quote which was very resonable. BE SURE TO GET SEVERAL QUOTES. ONE COMPANY QUOTED US DOUBLE OF WHAT WE PAID DIVERSIFIED. They were able to get a team out two days later. The team was on time, professional, and did really good work. We ended up needing a sump pump due to ground water coming up. They applied a mold application and completed the work in a day. I highly recommend these guys and did my research prior to having them do the work. I am very impressed and happy we chose them."

"Great company, called about a backed up toilet. They were able to come out first thing the following morning. Jordan and Jeremy showed up in the freezing cold and cleared the clog on the drain line very quickly. They also took extra time to scope and jet the line and found a busted pipe and extensive roots in the lines as well. They got everything cleaned out very quickly and left me with a product to help keep the roots away till we can get the pipe fixed and possibly get a liner installed in the future. I would recommend Zoom drain as they were fast, professional and reasonably priced. Thank you for great service."

"The workers were on time. Very efficient. They did a blower door test and found the air leaks and insulated these areas. Blew installation above the garage, cleaned out the crawl space and put new installation there and basement. Found a water leak from my toilet,Thank goodness. Covered everything in the basement and swept and cleaned up after. I would recommend them!"

"These guys did a great job on the drain cleaning and explaining to me how the drains were connected beneath and outside my home. I felt like the price was quite fair. I had gotten an estimate to re-do a french drain outside my basement after that experience, and I told them I would get back to them in a few months due to cost. It was a good price, but repairs are repairs, and most of them are expensive. I tried getting these guys out again a few months later, but I had a really hard time getting in touch with anyone. I was happy with the work from before, for sure."

Basement Waterproofing questions, answered by experts

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.

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.

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.
