Cost to Whole-House Dehumidifier Installation in Baltimore, MD (2026)
If you’re budgeting a whole-house dehumidifier installation in Baltimore, most projects run $1,852-$4,575, 9% above the $2,800 national average. What moves that number most is usually one thing: Unit Capacity (Pints per Day). On its own it can swing the cost by $400 - $1,500, so that’s the decision to slow down on before you sweat the smaller stuff.
Easiest place to save: Fix moisture sources first - sealing basement cracks ($200-$500) and improving grading may reduce your humidity enough to downsize the dehumidifier by one capacity tier, saving $400-$800
In the Northeast (where Baltimore sits): Moderate demand, basement humidity drives installations.
