Before you get a replacement quote, find out how much water your well yields. Check the installer's credentials. Ask which county approvals you need.
Match the pump to the well
Howard County's pump installation form requires a low water cutoff switch if the pump can draw more water than the well yields. A larger pump alone does not tell you how much water your well can supply.
The county's public well and septic records search covers 1985 to present. Use the construction record to start a conversation with your installer about your well. It does not tell you how much water the well yields today.

What a replacement costs
JW Well Pumps advertises $1,200–$3,500 for a full pump replacement on its Howard County page. Larger projects reach $4,000 or more. These are one contractor's marketing figures. The contractor gives no supporting price data there. They are not a county average or a quote for your well.

We could not find a reliable county-wide replacement price. Ask for a quote that separates pump work from any tank, supply-line or electrical work. Ask which approvals the price includes.
The permit question is still open
The county's plumbing fee schedule does not name well pumps in its list of fixture replacements. We could not tell whether a like-for-like pump swap needs a plumbing permit or the Health Department's installation inspection. The installation form deals with Use and Occupancy approval. It does not answer that question for an existing home.
Two public sources also disagree on the well permit price. The Health Department lists $160 for well permit, inspection and sampling. State law caps that charge. Maryland OneStop lists $0 estimated cost for a Howard County well permit. Neither tells you the fee for replacing just a pump.
(Health Department schedule revised July 2024; plumbing schedule effective 1 July 2026; both and OneStop read 21 September 2026.)
Credentials and completion
The county form asks for the responsible installer's name and licence number. It names licensed plumbers, well drillers and well pump installers. The state rule spells out an exception for plumbers. A master plumber may install or repair pumps without a licence from the Board of Well Drillers. The form's broader wording does not mean every plumber qualifies for that exception.
Your installer must disinfect the well after fitting the pump. Maryland's pumping-equipment rule says so, and it covers the pump and the water supply system too. Howard County also recommends testing your water after well repairs. You can find collection and laboratory fees on the water testing page.
