"Initial rep was great and informative. Felt comfortable with initial sale. Hardly had any contact from customer service except for the payments. There were several delays that we were not informed about unless we called to ask. Took 7 months before they showed up to begin project. Only 1 person was sent to build steps. Took a week. Hard worked, hardly took a break. Had to call again to see when they would come to pour patio. Never knew when they were coming, they just showed up. Hardly spoke with the homeowners. Inspection paperwork was just left on porch. Additional paperwork that is "required by the County" had to be completed by homeowner and taken to Court house to be notarized and filed and also provide a copy back to Long Fence. Time sensitive materials which added to homeowners to-do list. Gave this contract to LF on the surface of their history and appearance of a 'good local company' but should have stayed with original contactors in VA. Puddle of water forms when it rains"

Mid-Atlantic Deck and Fence Co. was established in 1987. We specialize in all aspects of construction, related to the decking and fencing industry. If you are looking to have one of our beautiful backyard resorts constructed by us for you. Or if you are the type of person that would like to do it themselves than we can help. DON'T WAIT CALL TODAY!!!!!!!! 1-800-833-9310 let's get started.

"If I could give this company a zero I would. Completely disorganized, took months to complete my job with countless mistakes: (I requested the job in April, they started 4 months later, they incorrectly measured the fence area resulting in an incomplete fence for another month, recorded the permit for the fence on the wrong lot with county so had to have that reapproved and finally all the caps of the fence flew off after installation so I had to get a separate company to fix their work. Beware of Randy Fike with his unprofessionalism. Never again!!!"

FAQs for swimming pool or accessories repair or service projects in Gaithersburg, MD

A well-maintained, correctly sized pump lasts eight to 12 years. Help it reach the upper end of that range by cleaning the strainer basket, monitoring for unusual sounds, and verifying that the pump’s flow rate matches the filter's specifications. Address leaks or pressure dips quickly—minor fixes now cost far less than a premature replacement later.

Listen for grinding or screeching, watch for breaker trips, and keep an eye on sudden spikes in your electric bill—any one of these signals the pump needs attention. If repairs continue to accumulate or the unit is older than eight years, replacement often makes more financial sense. Contact a qualified pool repair professional immediately to diagnose the issue and prevent further damage to the filter or plumbing.

It’s best to keep your pool pump on while swimming. Keeping the pump on while you swim allows the filter and skimmers to catch debris in real-time, maintaining water features flowing. It’s not mandatory, but weaving swim time into your regular eight-to-12-hour schedule helps maintain crystal-clear water and consistent chemical levels without extra effort.

Start by shutting off the power at the breaker and verifying with a voltage meter. Close the water valves, bleed pressure, and unbolt the old pump. Wire the new unit according to the manufacturer's diagram, glue in the PVC unions, prime the housing, and tighten everything securely. Open the valves, flip the breaker, and watch for steady water flow and quiet operation. If any step feels beyond your expertise, consider hiring a licensed electrician or pool technician.
