"Burst pipe and flooded basement? Who ya gonna call? You cannot do better than to call My Carpet Cleaning & Restoration Service: proprietor Rich Gakaivian and his helpers (Ahmet and Ahmet) arrived quickly when that unfortunate situation occurred at our home near Aspen Hill, MD hon 1/24/26 and provided superb immediate mitigation, staying until the 3” of accumulated water was fully pumped out, setting up a dehumidifier fully dry the unfinished basemen t’s cement floor. sweeping The next day’s area-wide immobilizing snow and ice storm and delayed plowing left our street impassable for a couple of days, but as soon as conditions allowed the crew returned to sweep the dried floor and complete haulaway of the many large contractor bags of unsalvageable debris. Today Ahmet and Ahmet returned to complete the restoration phase by installing new insulation in place of that which had been drenched by the water pouring from the burst pipe. Throughout the process, including during the weather-driven delay, Rich maintained regular communication re conditions at his end and anticipated timing for finishing the job, effectively eliminating any frustrations attending the unavoidable delays. All in all, My Carpet Cleaning and Restoration Service has been a great company to work with—friendly, competent, honest, and reasonably priced … who could ask for more? I cannot heap enough praise on this company. Definitely 5 stars out of 5. Bonus: While unrelated to the original contracted mitigation/restoration service, after finishing Ahmet offered while here to repair a shaky door that has been a problem we’ve just put up with for some years at a very reasonable price.

"We recently worked with Flood Solutions after our basement flooded, and Megan—our inspector and project manager—was incredible. She was thorough, patient, and took the time to explain every step of the process, which meant a lot as an allergy sufferer worried about proper remediation. She honestly deserves her own show on mold education! When the team arrived, they were organized, detailed, and clearly cared about doing things the right way. Matthew and the crew also did a fantastic job finishing everything and making sure we felt informed and comfortable throughout. We can’t recommend Flood Solutions enough. If you need a trustworthy team during a stressful time, call them—and hopefully you get Megan, she’s a gem!"

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."

FAQs for toxicity and mold removal projects in Baltimore, MD

Remediation should keep mold from returning as long as the moisture source is eliminated. Fix leaks, control humidity, and replace water-damaged materials, then schedule periodic inspections to stay ahead of new growth. With those safeguards, your home can stay mold-free for the long haul while protecting both health and property value.

Most pros recommend leaving the home while they work on mold remediation. Removing mold stirs up airborne spores that can aggravate respiratory issues, and contractors can work more efficiently in an empty space. A short, temporary relocation keeps everyone in your family safe and lets the crew finish the job without interruption.

Mold shouldn’t return once the moisture problem is fixed. Stay vigilant: repair leaks right away, keep humidity below 50 percent with a dehumidifier placed in damp areas, and improve ventilation where needed. Routine checks for leaks and mold and quick repairs go a long way toward keeping your home mold-free.

Mold spores can trigger nasal congestion, throat irritation, coughing, wheezing, eye irritation, or skin rashes. People with asthma, allergies, or weakened immune systems often feel the effects sooner and more intensely. Some molds also release mycotoxins linked to serious respiratory or neurological issues. Swift remediation and better ventilation are the best defenses.
