Basement Leak and Crack Repair in Annapolis, MD for Wet Walls and Foundation Cracks
We repair basement leaks and foundation cracks in Annapolis homes. Water gets into a basement wall through a crack, a joint, a pipe penetration or the wall material itself, and the repair depends on which. Call Annapolis MD Basement Waterproofing at 123-456-7890 for a free estimate.
We start by finding where the water comes in and where it comes from. A crack gets sealed, a joint gets repaired, and the water outside the wall gets sent somewhere else.
What We Do About Basement Leaks and Cracks in Annapolis
We find where the water enters
We look at the wall, the floor joint and the cracks while the basement is wet or marked damp, and we check the outside of the house for the water that feeds the leak. The Maryland Geological Survey attributes the majority of wet basements to the house foundation, landscaping and grading, not to rising groundwater.
We seal cracks that let water in
HomeGuide says epoxy injection seals minor cracks and lists it at $250 to $800 or more per crack. We inject the cracks that leak and tell you which ones can be left alone. Interior basement waterproofing
We do not paint over a leak
HomeGuide notes that sealers add a moisture barrier but "won't stop water under pressure." A coating over a wall that leaks under pressure fails, so we repair the entry point and add drainage when the water keeps coming.
We tell you when a wall needs more than a seal
HomeGuide lists bowed walls and warped doors among the signs of a basement problem. A wall that is bowing or shifting is a structural question, not a sealing one, and we tell you when an engineer should look at it before any repair.
Work is performed by independent professionals. Every project starts with an inspection and a written price before any work begins.
How We Repair a Leak or Crack
First, we inspect the wall, the floor joint and the crack, and we check the gutters, downspouts and grade outside. Second, we find out whether the crack leaks, grows or sits beside a bowed wall. Third, we write the plan with the repair, any drainage and the price. Finally, we seal the crack, install the drainage if it is needed and walk the repair with you.
Why Annapolis Basement Walls Leak
The NOAA climate normals for the Annapolis NAF, MD station (1991-2020) record 43.99 inches of precipitation a year, with 8.20 inches in the driest season, winter, and 13.25 inches in summer. The wall sees rain in every season. Census Bureau figures (American Community Survey, 2020-2024) show about 59% of occupied Annapolis homes were built before 1980, so many walls and joints have decades of wet weather behind them.

What Leak and Crack Repair Costs in Annapolis
HomeGuide's national guide (written January 23, 2026) lists epoxy crack injection at $250 to $800 or more per crack, and sealers such as waterproof paint or concrete sealing at $2 to $10 per square foot. It lists interior waterproofing at $6,000 to $12,000 on average, which covers drainage when sealing is not enough.
Those are national averages, not Annapolis quotes. The number of cracks, how they leak and whether the wall needs drainage set the price for a specific home. What basement waterproofing costs in Annapolis
Frequently Asked Questions
Why is my basement wall leaking?
Often the cause is at the foundation or outside it. According to the Maryland Geological Survey, most wet basements are caused by foundation, landscaping and grading issues, not by rising groundwater. Cracks, wall joints and the grade outside are the first places we look.
Can a crack be sealed from the inside?
Minor cracks, yes. HomeGuide says epoxy injection seals minor cracks. For a crack that keeps leaking under pressure, we also look at the water outside the wall and add drainage.
Are cracks in my basement wall serious?
Not always. Many are dry and stay dry. A crack that leaks, grows or sits beside a bowed wall is a different case, and HomeGuide lists bowed walls among the warning signs. We look at the crack, the wall and the water and tell you which one you have.
Will waterproof paint stop my wall from leaking?
Not if water is pushing through the wall. HomeGuide says sealers "won't stop water under pressure." We fix the entry point and the water outside the wall.
Do you repair foundation cracks outside the basement?
We repair the cracks that let water into the basement, from inside or from outside when the wall is exposed. If a crack points to a structural problem, we tell you when an engineer should evaluate it.
