The team was professional, thorough, and incredibly detail-oriented from start to finish. They took the time to explain the process, ensured everything was spotless, and left my home noticeably fresher and healthier. Their level of expertise and customer care is truly second to none. I highly recommend this company not only for residential work but also for any commercial building in need of cleaning, maintenance, or full refurbishment. If you want the job done right the first time, this is the team to call. Dwayne...for my mother, Gloria

I…read moream sitting here with my daughter who just remarked that the air smells fresher- I agree , and the air flow from the vents is noticeably improved . These guys work like Americans of my parent's generation worked - that old school work ethic. Get on it, get it done, and take pride in your work, honesty and integrity. I recommend them in a heartbeat. So incredibly thorough. Every vent snaked out, vacuumed, disinfected. Vent covers cleaned, including bathroom fans and dryer vent to outside. No stone left unturned. Easy to schedule, punctual, good communication, an extremely great price given how energetically they worked every minute of the two hours on site. OUTSTANDING !!! .

I called on a Friday after being recommended here. My central air conditioning unit in my home had…read morebeen running constantly and often would be higher than what it was set at. I was booked for that Monday! The day of my appointment, I was called several hours before my appointment to say they had an earlier than expected time slot and wanted to know if they could come now. Unfortunately I couldn't do earlier than scheduled but appreciated them asking! My time slot was 4-6 pm. They showed up at 4:05! Wow! I can't tell you how many times companies give time slots and show up hours AFTER the time frame. But not Markool! They are on it! Jorge and Jose were my technicians. They were both very friendly and went right to diagnosing the issue. After about 30 minutes, they figured out I needed Freon. I asked the pricing and they had a tablet to look up the pricing right away. If you need Freon be warned it's expensive! Not this company's fault though it seems to be commonly expensive when I looked online out of curiosity. These two technicians were knowledgeable and explained everything. They were super polite as well. They emailed me my invoice with pictures of everything they did today. I highly recommend Markool for your cooking needs!

I just want the job done so with the same price agreement I give the job to these guys. They show up, and the tech cannot get the fireplace vent door open so I get another call from the wife asking me how to open the door. Then, they tell me that it's $149 plus $20 per foot of the chimney. That's not what the stated cost was, and the supervisor says "well we charge what we charge." I told him to leave. This is bad faith business, and it wasted a truckload of my time today. This is not how to win projects, and you should not win anymore bids if this is how you choose to do business.

As I took another step, my foot sank into the carpet, leaving behind a soggy footprint. One more step, and I could hear water sloshing beneath the carpet. Ugh, our basement was leaking! I searched for help online and found AdvantaClean of Frederick. After reading their excellent reviews, I gave them a call--and I'm so glad I did. I spoke with the owner, Dave, and it was clear that he knew exactly what he was doing. He was calm, knowledgeable, and reassuring, which helped us feel less overwhelmed. Dave got us on the schedule right away, which was such a relief. He reviewed the basement, provided us with a reasonably-priced quote and we gave him our business. He and his team arrived promptly and got right to work. Using specialized equipment, they were able to pinpoint the source of the leak. They carefully removed our water-damaged sofa along with several bags of damaged items, and they did it all with care and efficiency. They then sealed off the affected area with plastic sheeting and neatly removed the damaged drywall. Dave set up industrial fans and a dehumidifier to dry everything out over the course of several days, staying in communication with us the entire time and periodically stopping by to monitor progress. Dave is not only professional, but also has a good sense of humor and is easy to talk to. He was quick to respond to texts and answered all my questions clearly and thoroughly. If you ever find yourself in the stressful position of dealing with a water-damaged basement, I can't recommend Dave and AdvantaClean of Frederick highly enough. They truly went above and beyond.
