Oriole Basement Waterproofing · Maryland
Other Services
Beyond our four core specialties, Oriole handles sump pumps, egress windows, exterior drainage, mold remediation, and ongoing maintenance — all under the same Lifetime Transferable Guarantee.
Sump Pumps & Battery Backup
Primary sump pump installation, replacement, and repair. Battery backup systems that keep your basement dry when Maryland storms knock out the power.
Egress Windows
Egress window installation and replacement to meet Maryland building code requirements for basement bedrooms, home offices, and finished living space.
Exterior Drainage
French drains, grading, downspout extensions, and yard drainage systems that redirect water away from your foundation before it becomes a basement problem.
Mold Remediation

Maintenance Plans
Annual inspections and ongoing system maintenance to keep your waterproofing performing — and your Lifetime Transferable Guarantee in full effect.
Not Sure What You Need?
Our inspectors diagnose the problem first — then recommend only what's warranted. Free inspection, written quote same day. No commissioned salespeople.
