Tri County Pool Supply

Tri-County Pool Supply builds in-ground pools, sells pool chemicals, filters, pumps, covers, heaters and accessories, and runs ongoing maintenance plans for pool owners. The company also builds stamped concrete patios and walkways, fire pits, and outdoor structures such as gazebos and pavilions. It has been in business for more than 20 years and serves Bel Air and surrounding Harford County, with customers in the wider Baltimore area.

Maintenance comes in three tiers that cover cleaning, water testing and repairs, and plans can be tailored to a household's schedule and budget. Staff can help choose products for a new or existing pool. The company also emphasizes environmentally responsible practices and offers eco-friendly products. The business is based in Bel Air, and its retail store is part of the same operation.
