Your We Love Fire Expert

Costello’s Hearth & Spa / Fallston, MD

Right on Fallston Road, sharing the same address as the local Ace Hardware, you’ll find a showroom that doesn’t feel like a big-box stop at all. It feels like the place your neighbor told you about because they actually bought their fireplace there. Costello’s Hearth & Spa in Fallston grew out of the same family of businesses that’s been serving Harford County home and hardware needs for decades, and that heritage shows in the way the team treats every visit. Unhurried, honest, and genuinely more interested in matching you with the right gas fireplace or hot tub than in pushing whatever’s on the showroom floor. Between the fireplaces, stoves, inserts, hot tubs, swim spas, and even cold-plunge tubs under one roof, there’s remarkable range here for a neighborhood store, and it’s backed by factory-trained technicians who handle the installs and repairs themselves rather than farming the work out. WeLoveFire.com is proud to count Costello’s Hearth & Spa in Fallston among our preferred dealers. This is exactly the kind of shop we look for, one where the expertise is real, the service continues long after the sale, and the people behind the counter genuinely make homes safer, warmer, and more enjoyable.

Company History

The story starts small: back in 1997, Costello's opened as a modest fireplace shop in Maryland, the kind of place that grew one satisfied customer and one referral at a time. Nearly three decades later, that single shop has become an industry-leading name with fireplace, hot tub, and swim spa showrooms stretched across Maryland, New York, New Jersey, and Virginia. But the Fallston location still carries that original, close-to-home feel, in part because it operates alongside Costello's Ace Hardware, part of the same extended family of businesses that has always put local service first. Along the way, the company built out specialty divisions like Ace Home & Leisure, Costello's Hot Tubs, Tri-County Hearth & Patio Center, and All Pro Chimney Services, each one adding depth of expertise rather than just adding locations. It's a growth story built on the kind of patience and consistency that's hard to fake. Three decades in, they're still the same company that started with one fireplace shop and a commitment to doing right by the customer in front of them.

Product Summary

This isn't a store where you wander the aisles alone trying to decode spec sheets, it's a curated selection of premium hearth and backyard wellness products with people on hand who can explain the real differences between them. Inside, you'll find fireplaces, stoves, and inserts running the full range of fuel types (gas, wood, electric, and pellet) from respected manufacturers, so whether you want the low-maintenance convenience of a gas insert or the authentic crackle of a wood-burning unit, there's a genuine option rather than a one-size-fits-all pick. On the relaxation side, the lineup expands into hot tubs and swim spas, plus a newer addition in cold-plunge tubs for anyone chasing the recovery and wellness benefits that have become so popular lately. It's the kind of selection that rewards a little browsing and a lot of conversation with the staff, exactly the experience a specialty hearth and spa dealer is supposed to offer.
