Well Abandonment & Sealing in Central Maryland

Well Abandonment · Central Maryland

Old Wells Don't Just Get Left. They Get Sealed.

Well abandonment is the job almost nobody thinks about until a county, a lender, or a home sale forces the question: what happened to the old well? An unused well is a direct, open pipe into the groundwater — a safety hazard on the surface and a contamination pathway underneath. Across Montgomery, Frederick, Carroll, Howard, Washington and Baltimore counties, we seal abandoned wells properly: cleared, filled and grouted to the standards your county health department requires, with the paperwork to prove it.

The work pairs naturally with drilling a replacement well — the old well gets sealed as the new one goes live — but we also close orphan wells found on newly bought land, wells left behind when a property connected to public water, and old hand-dug wells hiding under backyard slabs. If you have a well you do not use, sealing it is not bureaucracy; it is protecting the water everyone around you drinks.

What We Handle

  • Abandoned and unused wells sealed to county standards
  • Old wells cleared of pumps, pipe and debris first
  • Grouted bottom-up so the seal is continuous
  • Hand-dug and drilled wells both handled
  • Paired with replacement drilling when needed
  • Documentation for the county, lenders and sales
  • Hazardous open wellheads made safe
  • Free on-site estimates

Why an Unused Well Is a Real Problem

On the surface, an old well is an opening a child, a pet or a mower wheel can find. Underground, it is worse: a forgotten well short-circuits the ground's natural protection, letting surface runoff — fertilizer, road salt, bacteria — pour straight down into the aquifer your neighbors' wells draw from. That is why proper abandonment is a regulatory requirement, not a suggestion.

Old wells also complicate transactions. Home sales, refinances and building permits increasingly surface the question of any well shown in county records — and an unsealed, undocumented well can stall a closing. Sealing it properly, with documentation, closes the file permanently.

What Proper Sealing Involves

Real abandonment is more than dumping dirt down a pipe. The well first gets cleared — pump pulled, drop pipe and wiring removed, obstructions cleared — because a seal poured on top of junk is not a seal. Then the borehole is filled and grouted from the bottom up, so the sealing material sets as a continuous plug instead of bridging over voids that later collapse.

Depth, casing condition and the well's construction decide the exact procedure your county requires; we handle the requirements and the notification paperwork as part of the job. What you keep is the documentation — the proof that the well was sealed correctly, by people who do this for a living.

Found a Well You Didn't Know You Had?

It happens constantly in Maryland's older farm country: a pipe in the weeds, a ring of stones under a shed, a plate in a basement floor. Properties out here often carry generations of water history — the hand-dug well by the original farmhouse, the first drilled well that went shallow, and the modern well actually serving the house.

If you have found something you suspect is a well, do not fill it yourself — an improvised fill can void the ground around it and makes proper sealing harder later. Get us to take a look: we will identify what it is, tell you whether it needs sealing, and quote the job free. If you are also weighing what to do about a failing active well, we will lay out the revive-or-replace math at the same visit.

What You Can Expect

How a Job With HydroWells Runs

From the first look at the property to water proven at your tap, here is exactly how it goes.

1

Look at the Property

We come see the actual situation — the well, the equipment, the water, the ground. What's failing, why, and what the fix really is. No blind quotes over the phone.

2

Straight Quote

You get a free written estimate with a real number and a real plan. It says what's included — drilling, equipment, connection, permits — and it holds unless the scope changes.

3

Do the Work

The crew shows up with the right equipment and does the job the way we quoted it — drill, frack, pull the pump, set the tank, build the treatment. Anything unexpected, you hear about it immediately, not on the invoice.

4

Prove the Water

We don't call it done until the water proves it: yield checked, pressure steady, system cycled, and testing when the job calls for it. Done means water at your tap — and you saying it's done.

Call (301) 393-7090

Do I have to seal an unused well?
In Maryland, abandoned wells are required to be properly sealed, and county health departments enforce it — commonly at property transfer or when a replacement well is drilled. Beyond the requirement, an open well is a genuine safety and groundwater hazard. Sealing it closes the risk and the paperwork.
Can I just fill the old well myself?
No — and not only because of the rules. An unclear well filled from the top bridges and collapses, leaving voids that funnel surface water into the aquifer anyway. Proper abandonment clears the well and grouts it bottom-up so the seal is real. It is not a shovel job.
How much does well abandonment cost?
It depends on depth, diameter, what is still down the well, and access for equipment. We look at it, quote it free and in writing, and handle the county requirements as part of the number.
The old well still has a pump and pipe in it. Is that a problem?
It is normal — most abandoned wells were simply switched off and left. Pulling the old equipment is the first step of the job and is included in how we quote it.
We're drilling a new well. Does the old one have to be dealt with?
Typically yes — sealing the failed well is part of the replacement process, and we handle both ends: the new well drilled and connected, the old one cleared, sealed and documented. One crew, one schedule. Call (301) 393-7090.
