Cost to Whole-House Surge Protector Installation in Baltimore, MD (2026)
If you’re budgeting a whole-house surge protector installation in Baltimore, most projects run $211-$527, 5% above the $350 national average. What moves that number most is usually one thing: SPD Type and Joule Rating. On its own it can swing the cost by $30 - $200, so that’s the decision to slow down on before you sweat the smaller stuff.
Easiest place to save: Buy a plug-on SPD that matches your panel brand (Square D, Eaton, Siemens) for $30-$80 - installation is faster and cheaper than hardwired units
In the Northeast (where Baltimore sits): Higher electrician rates.
