Clients trust DES for our reliability and results, leading to a strong referral-based business and consistently high rankings on contractor-rating platforms.
""After 15 years of enduring water and flooding damage to our yard and the foundation of our house, and after trying various 'solutions' from well-intentioned landscapers that never truly resolved the issues, we ultimately decided to engage Drainage and Erosion Solutions. We required comprehensive flood control and damage mitigation, and their expert team skillfully implemented swales, dry creeks, catch basins, and channel drains in areas where water management was critical. They also replaced a water-damaged window well, removed a flagstone patio to install drain basins and drainage pipes, and flawlessly reinstalled it. The supervisor and crew displayed remarkable knowledge, professionalism, and an unwavering commitment to detail throughout the entire project. This system has been operational for several months now, and even during the most intense rainfall, which historically led to road flooding, my house and foundation remain dry. We enthusiastically endorse this company without reservation.""

Atlas Home Energy Solutions is committed to providing the highest quality home energy improvements to homeowners interested in reducing their utility bills and improving the comfort of their home year round. Customer Satisfaction is our number one priority and we promise that we can make a real impact in your home in a way that keeps you happy every step of the way.
"Atlas home energy solutions did an outstanding job from start to finish. They were professional, knowledgeable, courteous and easy to work with. All the crew members Ben Mott (was very knowledgeable, did the home energy audit, followed up with competitive quotes, which was adjusted to accommodate my request, offered BGE rebates upfront, patient and friendly to attend my calls and answer all the questions), Zam (Crew leader who did the exhaust fan installation), Tun (Crew leader who did an outstanding job to insulate the attic and basement), David (Crew leader who did duct cleaning and Aeroseal) were phenomenal and did an outstanding job. The end result is a day and night difference before and after the work and my BGE bill last month went down by more than $100 which is a huge cost saver. The HVAC does not run that much these days and the temperature is pretty even across the 30-year townhouse. I highly recommend Atlas home energy solutions for home energy audit and improvements."

When Glenmont Heating & Air Conditioning was founded 28 years ago, we had one goal in mind; providing area families, and businesses with solutions that fit their lifestyles and needs, as well as their wallets. If you have any questions about heating and air conditioning maintenance, a new HVAC system, or are looking into installing a more energy efficient system, Glenmont Heating and Air is the solution to your needs.
"Summary: Company charged me $1000+ for 2 separate service visits that did not fix my AC unit; technicians and Operations Manager are not truthful about work done; Operatiins Mngr will tell you find another HVAC company when you express dissatisfaction ….I contacted Glenmont Heating and Air Conditioning since my AC unit was not dispensing any cold air. Thermometer was set to 68° however the unit temperature was reading 77-80° (note this was the week of extreme heat wave). On 21Jun2024: Glenmont technician Roderick performed a service call. I spoke to him via phone after the call to which he told me he added refrigerant to the system. This did not fix the issue and the unit continued to not dispense cold air with the thermometer reaching 77-80° despite being set to 68°. I was charged $119 for this work. Operating Manager Tim Schindle is contradicting what the tech said and claims Roderick did not add any refrigerant. I again called Glenmont HVAC for a second service appointment. This technician claimed the coil needed to be cleaned. The second technician (Eric) then falsely reported on his report the unit temperature dropped to 68° when he left when I have photographic evidence showing the temperature in the high 70s. I waited about 24hrs as instructed for the thermostat to drop and it never did and the unit continued to not dispense cool air. I then called a supervisor (don’t recall name) who essentially told me due to the extreme temperatures everyone was experiencing HVAC issues and did not recommend any follow up service. I then had several back/forth emails with Operations manger Tim Schindler to notify him after 2 separate service visits, my air conditioning was not fixed. In the end he told me, and I quote “my system is old…we don’t know the maintenance history…it is best for both of us to find another HVAC company. He did however bill me $964 for the second service visit, which did not fix my issue. I ended up having to call another HVAC company who diagnosed the problem as a compression failure/ replaced the unit and now have cold air blowing. The second HVAC company did not understand why the 2nd technician from Glenmont Heating/Air Conditioning was changing coils and said this was not necessary to do. Second HVAC company showed me the reading of the compressor unit to which I could see no charge was registering, essentially the compressor was no longer working which was the root cause of my issue. In conclusion, I’m disappointed with Glenmont HVAC and feel they sent incompetent technicians who falsified their work. When I complained to the company and expressed my disappointment with their work (or lack there of) they told me to seek other HVAC company without fixing my AC unit but charged me $1000+. Poor business acumen and highly unethical company that needs to be held accountable for cheating customers and not performing quality work."

"🚨 Avoid Len the Plumber – Negligent & Unsafe! 🚨 I hired Len the Plumber to install a brand-new water heater, but it failed after two weeks. They promised quick service but left us without hot water for days. Worse, the first technician concealed a serious fire hazard—the heater’s electrical components had actually caught FIRE and burned! A second technician finally admitted the fire risk, meaning my family could have been in grave danger. This is pure negligence and completely unacceptable. They replaced the heater but only after multiple delays, zero accountability, and putting our safety at risk. 🚫 DO NOT trust this company with your home’s safety! 🚫"

Additional DBA - JCF Inc .
"Jimmy showed up to my home during a time when my thermostat was not working. That issue was fixed. He sold me a services contract and told me when he returned to services the units, he will cover the pipes outdoors. I purchased the contract for twice per year maintenance. I scheduled with him for a specific date. Appointment was confirmed but Jimmy did not show. When I called, he it appears that he forgot my appointment and he rescheduled saying he could not work in the rain. He rescheduled for a few days after and one of his workers showed up (Carlos). The guy showed up looking like he was someone who does not want to work and unprepared. So, I asked him if he has filters and he said know. Jimmy's workman did not bring filter, so I offered him filters I had stored. I asked him if he bought things to cover the pipes at the back, he said no. I called and left a message for Jimmy. Carlos was so rude and unprofessional. I was so scared of him and the way he was behaving. Carlos then said he would NOT do any service. IT WAS A WASTE OF MY TIME. He did return my money. BUT I will not recommend him. Will NOT use him again. As woman I will not hire again. Customer services was poor, reliability and punctuality poor."

"Hot water issue. Technician gave estimate for hot water tank replacement of 8 year old lightly used tankless. In light of the phenomenol price tag, did some homework. Hit the reset button. Fixed. Hmmmm. Maybe it was the tankless that confused him. Really glad it was a free estimate (unlike Len's who charged me $315 and didn't fix it)."

The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.
The average cost to unclog a drain is around $200, with prices ranging between $110 and $800, depending on the type of drain and the extent of the clog. Hiring a professional to snake the toilet or sink will usually cost between $110 and $275, a bathtub or shower typically costs around $225, and a main line clog can cost between $100 and $800 based on the severity of the clog and how far beyond the access point the clog sits. Since the labor involved varies, most plumbers will charge an hourly rate for drain cleaning.
Yes, most states require plumbers to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations.
