What We Do About a Wet Basement in Annapolis
We find the source of the water
We check the walls, the floor joint and the cracks, then walk the outside of the house for downspouts that empty at the wall, gutters that overflow and ground that slopes toward the foundation. The EPA's guide to mold and moisture says to clean and repair roof gutters regularly and to make sure the ground slopes away from the building foundation. Why is my basement wet
We fix the outside causes first
HomeGuide says regrading is occasionally enough on its own, at $1,000 to $5,000, and lists downspout replacement at $220 to $625. When the cause is outside the wall, fixing it costs less than a drainage system. Exterior basement waterproofing
We add drainage and a pump when water still gets in
When the water table rises or water seeps through the wall, we install drainage and a sump pump so the basement does not collect it. Interior basement waterproofing
We seal what is letting water in
Cracks and joints that leak are repaired so the drainage has less to carry. Basement leak and crack repair
Work is performed by independent professionals. Every project starts with an inspection and a written price before any work begins.
What to Do in the First 48 Hours
The EPA says it is important to dry water-damaged areas and items within 24 to 48 hours to prevent mold growth. Stay out of standing water near outlets, cords and the electrical panel. Move belongings off the floor, run fans and a dehumidifier once it is safe, and photograph the damage. Drying is the first job, and finding the source is the second. Mold remediation, when it is needed, is separate work, and HomeGuide's national guide lists it at $1,500 to $15,000.
How We Repair a Wet Basement
First, we inspect inside and out and mark where the water entered. Second, we check the gutters, downspouts and grade. Third, we write the plan with the outside fixes, the drainage, the pump and the price. Finally, we do the work and walk the finished basement with you.
Why Annapolis Basements Take On Water
The NOAA climate normals for the Annapolis NAF, MD station (1991-2020) record 43.99 inches of precipitation a year, and summer is the wettest season at 13.25 inches. The Maryland Geological Survey says the water table is typically at its highest in the spring and early summer months, and heavy rain can make infiltration into basements worse. A USDA Web Soil Survey of central Annapolis maps about 40% of the area as Annapolis-Urban land complex, and USDA describes the Annapolis series as well drained, so we check the gutters, the grade and the wall before we assume the water is coming up from below.

Frequently Asked Questions
Why does my basement flood after rain?
Rain reaches the foundation from the roof, the downspouts and the ground. According to the Maryland Geological Survey, most wet basements are caused by foundation, landscaping and grading issues, not by rising groundwater. A high water table after heavy rain, cracks and wall joints are other causes. We inspect inside and out and tell you which one you have.
How quickly do I need to dry a wet basement?
The EPA says to dry water-damaged areas and items within 24 to 48 hours to prevent mold growth. After that, the cause has to be fixed, because the water returns.
Can I fix a wet basement by pumping the water out?
Pumping removes the water that is there. It does not stop more from coming in. We find the source and add drainage and a pump to handle what still enters.
How much does wet basement repair cost?
HomeGuide's January 2026 national guide lists regrading at $1,000 to $5,000, downspout replacement at $220 to $625 and interior waterproofing at $6,000 to $12,000 on average. Those are national averages, not Annapolis quotes. An inspection shows which fixes your basement needs.
Does homeowners insurance cover a wet basement?
Coverage differs from policy to policy. Read your policy and ask your insurer whether water that seeps in or backs up is covered, and what your deductible is, before you file. Keep dated photos and a written repair estimate for the claim.
