Guardian Basement Waterproofing
Guardian Basement Waterproofing
Guardian Basement Waterproofing understands your basement waterproofing needs. We know how to detect the source of water intrusion and stop leaks before they happen. We help our customers reclaim their basements from water, mold and mildew by doing what we do best: finding and repairing the source of their water-related problems. Guardian uses only skilled and experienced technicians to do the job right the first time! As a basement waterproofing company with more than 40 years of waterproofing experience, Guardian stands behind its work with a Lifetime Guarantee. Additional phone number - (410) 484-9812.
"Avoid Guardian Basement – False Promises and Poor Customer Service Two years ago, I hired Guardian Basement to fix a water issue on the front wall of my basement. Joel came out, sold me on their system, and guaranteed I would have a dry basement. We also replaced two sump pumps and had the sump well dug deeper. The main selling point was their lifetime guarantee. Fast forward two years, and I have the exact same problem. Every time there is significant rain, water rushes through the same wall. I reached out to Guardian Basement, and Joel scheduled a time to check it out. His tone was completely different this time—defensive and dismissive. Within five minutes, he claimed, “Your system is clogged.” He made this assessment without any real inspection—just by looking at the cement floor and wall. Now, here’s the catch: If you look closely at their so-called lifetime warranty, clogs are not covered. So despite spending thousands of dollars, I’m back to square one. To make matters worse, Joel was incredibly condescending and unpleasant to deal with. After this experience, I looked into their licensing with the state of Maryland and found multiple complaints against them. I am now in the process of submitting my own complaint as well. I would never recommend Guardian Basement to anyone. Save your money and go with a company that truly knows what they are doing and stands behind their work. If I could give them a negative number of stars I would."

"I used 4u inspection to inspected a 2017 single family house. I had an inspection done virtually due to COVID which understandable but I was really disappointed with the service. The inspection was scheduled at 9:00, I was surprised inspection was done at 10:30 so basically an hour and half for a single-family inspection. I was moving some items to our house and in my first couple hours I see the inspector missed an obvious problem with the refrigerator, every time you open and close the fridge it makes a loud knocking noise, the noise is so obvious that I think he did not even open the fridge, 4 window shades had a damage cord, a window was not opening properly. I spoke to them on the phone before I post any reviews and the inspector manager was polite but claimed that the inspector is not suppose to check shades or windows and that they only need to check the refrigerator water connection and if it cold and it is not their responsibility to check if there is noise coming from the fridge ? . The roof was inspected the old way with binocular which has limited vision. Advanced inspections companies use drone to do this. I thought I would give an honest review for others to know what you might get from their service. I think I would have saved my self the inspection money and couple thousand dollars if I have done the inspection myself as all the issue found by the inspector were really minor but missing a major issue."
