I provide my clients with a comprehensive approach to contracting and specialize in a wide range of services.

My Services
Quality Service at Competitive Rates
Residential and Commercial
Well Pump Repair and Replacement
My clients are my number one priority, and I’ll go the extra mile to make sure they’re completely satisfied with my work. I use top of the line stainless steel Schaefer pumps with Franklin Electric motors. Most competitors give a one year warranty but I give a three year warranty for all pumps. Call me today to discover how I can help.
Well Tank Service and Replacement
I use Well-Rite tanks that are made in the United States from heavier steel than most other tanks. The tanks come with a five year warranty. I also offer maintenance on existing tanks that are over five years old.
Constant Pressure System
The Grundfos constant pressure system will give you maximum water pressure throughout your house regardless of your water usage. It will also free up much needed space by getting rid of the larger well storage tank.
Water Softeners and Carbon Filters
Water softeners will eliminate hard water which can cause staining of your appliances and fixtures. It will also prevent calcium buildup on fixtures. The softeners I use are larger than most competitors so there is minimal pressure drop in the well system. The valves are metered to lower the backwashing and salt needed. Carbon filters eliminate all unwanted taste and odors, especially the sulfur (rotten egg) smell.
Sediment Filter
Sediment filters protect your appliances and fixtures from fine sediment that could come from your well.

Review by Denise G. in Mechanicsville, MD
Comments: After my water stopped working I checked with HomeAdvisor and had three recommendations come up. D&D called very quickly and I set up to have him come out the next morning. The owner, I think his name was Donnie, could not have been nicer on the phone nor in person. He came out a few minutes earlier than our appointment time, , determined what the issue was and proceeded to explain all the details so I would feel at ease. A short 2 hours later I had a new well pump and running water again. I found D & D to be very nice, efficient and accommodating. The owner spent extra time and worked with my Home Warranty Service to be sure I could be reimbursed for most of the work done. I will use them again if needed and highly recommend them.

Comments: I called them early on a Sat. Morning because well was down. Donnie answered phone asked a few questions and said he would be at my house at 9am. They pulled in driveway at 8:67. Assessed the situation and in 2 hrs. Replaced well pump, supply piping, wiring, pressure switch and charged water tank. Cannot get much better than that

Comments: Donnie and his son were arrived when they said they would quickly diagnose the issue and fixed the problem. They went beyond what was needed replacing the pump and replace the pressure switch and filled the air chamber on the pressure tank to the correct setting.
