"Watermark carried out all defined services professionally and thoroughly. I received proposal within 3 days after requesting one. The proposed cost and work coverage was better than others I had received. Nick came to the house once I requested a proposal and reviewed the pool area so that his proposed work would be reflective of all conditions of the pool. The overall work was carried out professionally and the end result left me with a 'new pool'. The pool is relatively large (20 X 45)- 31,000 gallons and I now have a pool that is something I am proud. Nick stayed on top of all work in progress and kept me informed of each step and what was expected of each step. There were no hidden costs or surprises during the job or at completion."

"This is the second time that Dig M Pools did and installation for us. Again we were very happy with the job they did. We purchased our pool from them and it is a well made product. The owners wife was very helpful when we were deciding what pool to purchase. I would recommend Dig M Pools as first choice. Excellent job. Thanks Dig M."

"They were great.  Showed up earlier than scheduled which was not a problem at all.  Katie was very professional, listened to my explanation and set about repairing it.  From start to finish was less than a hour

"My pond is the healthiest it's ever been, I don't know if it's because of backyard ponds, or whatever? But I now have baby fish about 12 of them and I am going to hire them to do my winterization. I got a very professional reminder from backyard ponds in the mail today, and I really appreciate the reminder. Sometimes things like this slip your mind, but it's very nice that they remind you that winter is coming up, and you need to plan for the future. My fish are not expensive, because this is a newly renovated pond. But I'm very happy with the job that they did, and I will recommend them in the future. And I will be using them very soon"

"The owner of this company serviced our pool for over 15 years.  He was extremely responsible and professional.  He always responded to my calls promptly and made whatever repairs were necessary as quickly as possible.  He was always sensitive to costs of replacement items.  He also spent the off season going to classes and manufacturer training to be current in the industry.  His rates were reasonable.   When we were remodeling our pool deck and pool, he coordinated with the pool and deck contractors.  When our heater needed servicing he was knowledgeable enough to conduct the service himself.  Our pool was always crystal clear.  If he hadn't cut back with servicing our area, I would still have his company service our pool. "

"This was the best pool contractor sent to my home. The fact that he was an Electrical Engineer allow him to address electrical issues I was having with my pool equipment rather that having to purchase a new pump or other items. The individual was very professional and knowledgeable. I appreciate the fact that he was very personable and appreciated me as a customer."

FAQs for swimming pool or accessories repair or service projects in Frederick, 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.
