"Working with DJ from Groundworks (Select Basement) has been an outstanding experience. After struggling with various contractors who either failed to resolve our water issues or were unprofessional, DJ and his team truly stood out. DJ was incredibly helpful, patient, and responsive throughout the entire process. Our home is a ranch with 225 linear feet around the perimeter, and while other contractors insisted on installing a French drain for the entire length, DJ recommended a more targeted approach. He proposed installing the French drain for just 80 linear feet, focusing only on the areas where water intrusion was likely. His thorough explanations and prompt responses to all our questions were greatly appreciated. The workers arrived on time, maintained a clean work environment, and completed the job as promised. If we could give 10 stars, we would! Groundworks is a highly professional and honest company that didn't try to inflate the scope of work to charge us more. We wholeheartedly recommend them."

"I gave this man $3000 which was 33% of the job upfront. Was supposed to give him 33% at the halfway part And 34% upon completion. But when I went to my bathroom and realized you left drugs in my bathroom and I have small children. Not like that 3000 black and small cleaners caught easy and heâ s lucky he hasnâ t been charged with nothing. Only reason that happened is because I wouldnâ t pursue charges. He obviously is a drug addict and has a problem so maybe he should get help Possibly isnâ t the option maybe rehab is. If you paid for supplies, you got ripped off wait 10 years and it will all fall apart charges for certain stuff but buys different stuff so he can use the extra money to pick himself up drugs without nobody noticing, I am so terribly in grief over this. $3000 he ran off with how is Matt doing in business and not in a jail cell"

These guys came in and put a round small cylinder well. Water pumps up into our yard turning it into a swamp. Called them to come and see the problem they created. Their response $2900 to fix THEIR DAMAGE. I WOULD NEVER RECCOMEND THIS COMPANY!!"

Basement Leak Repair questions, answered by experts

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.

The best basement waterproofing method depends on the issue you’re trying to solve. For example, if you have standing water on your basement floor, a floor drain or sump pump might be your best solution. Or, if you have standing water around your foundation, installing a drainage system that protects your basement and foundation might be better.

The frequency with which a French drain clogs depends on various factors, such as the amount of debris that enters the pipe, the quality of the French drain installation, the type of grate and filter used, and how often it is maintained. That’s why it’s recommended to clean your French drain at least once a year, whether it is clogged or not. This can prevent clogs and increase the lifespan of your drain.

Trench drains have a bit of a reputation as being difficult to clean, so if there’s a massive rainstorm that leads to a lot of debris and gunk getting stuck in the drain, you’ll spend extra time cleaning it out. Plus, you definitely need to regularly clean the drain, heavy rainstorms or not, to keep it in good condition, adding an extra step to your cleaning to-do list.

Water that pools on concrete indicates a low spot somewhere on your driveway. You can level the slab with a concrete patching compound to help redirect water. You can also install drainage over existing concrete by digging out enough space for a channel drain or French drain or by adding a culvert below the slab.
