"Woke up this morning to my hvac leaking and contacted Markool. I have never used them before and was in a pinch. They fit me right in this morning and were out at my house within 2 hours. The tech stepped in the door and placed covers for his shoes so he did not track in any dirt which was impressive! The tech was very professional and super friendly. Problem was diagnosed and FIXED within an hour. The price was extremely reasonable to the point I was shocked in a good way (expecting a higher price). Anyways, I will most certainly be a returning customer. Thank you Markool Heating Cooling Plumbing."

"We had a tremendous experience with JES Foundation Repair. Chad was the Certified Inspector, and the work crew was Mike Boines, Corey Griffin and Deontae Jackson. The initial inspection and estimate was thoroughly explained, all appointments were on time and every step in the process was discussed. All discussions were very professional. Foundation repair and sidewalk "lifting" were all completed with satisfaction."

"STAY AWAY!!!! This Company cancelled the initial estimate on me 3 times making me drive 90 minutes to the property each time. They finally showed and gave me the typical hard sell "if you sign the contract today..." They gave us a quote so far over market value we should have walked away. But we agreed because of the "70 year history in the industry" We thought we were buying a service from a company with integrity. They took an immediate $18K deposit on a $55K project. I know, shame on me for agreeing to such an amount. We knew we were over spending, but... One month later, they simply cancelled the contract without explanation and without any work on the project. This contract was binding on us but, in their words, was not binding on them because "there's a clause in the fine print that allows them to cancel" THEY STILL HAVE OUR MONEY and I STILL NEED A ROOF Stay away from this company. No integrity No responsibility Unreliable Over priced Will take your money and keep it"

If you are looking for a HVAC Contractor, a Plumbing Contractor, or an Electrical Contractor to provide you with great service, you've come to the right place. We provide heating services, air conditioning services, plumbing services, and electrical services to our customers in Frederick and the surrounding Counties, the Pan Handle of West Virginia, and Northern Virginia, from our offices located in Frederick MD. With 3 generations of experience in providing heating, air conditioning, plumbing, and electrical services, we are dedicated to providing the best possible products and services for you, and your family.
"Tri State was prompt—they had a tech out within hours when our 20-year-old HVAC broke down. The repair estimate was $800–$1,200, and they also sent a salesman, Mike, to discuss replacement. Mike was courteous and knowledgeable, but, when we sat down to review the quote, the sales process turned into a bad car-buying experience. They started at $34,000, then "discounted" to $29,300—$10,000 -$12,000 higher than other quotes for the exact same unit. Even factoring in their warranty, they remained $8,000–$10,000 overpriced. Mike also claimed they were a four-generation family-owned business, but I later found out they’re owned by Sila Services, a Goldman Sachs private equity firm—which feels misleading. To their credit, canceling was easy (though I hadn’t signed a financing agreement or put money down). Bottom line: Get multiple quotes. Their pricing was excessive, and the sales tactics felt manipulative."

Sump pumps last about 10 years with proper maintenance and prompt repairs. Several factors can influence your sump pump’s lifespan, such as usage, environmental conditions, and installation. Premium sump pumps with heavy-duty motors and quality components tend to last longer than lower-cost models. Pedestal sump pumps usually last longer than submersible models since they’re not constantly exposed to water.
A basement French drain is a drainage system installed in basements or around a building’s foundation to redirect water and prevent flooding. This system features a trench with a perforated pipe that catches and transports water away. These systems can crack, freeze, or clog, potentially resulting in flooding or strain on your sump pump.
You can use a sump pump in your yard to minimize pooling water and landscape damage, but it’s best used in conjunction with other drainage systems. This can include French drains, trench drains, underground downspouts, and other equipment. Proper lawn care, such as soil aeration and native plants, also aids with drainage.
