Lennox Fireplace Doors — Compatible Custom Replacements
Lennox Hearth Products built prefabricated wood-burning and gas fireplaces from the 1980s through 2018 (when the hearth division was acquired by HHT). Many Lennox installations are now reaching the 15-25 year point where factory glass doors need replacement. Custom doors at ExceptionalFire fit all major Lennox models, ship free across the continental US, and are built to outlast the factory units.
Lennox prefab series — what we replace
- Hearthstone / Brentwood (wood-burning)
- Montecito / Montebello (premium wood-burning)
- Brookhurst / Cottage / Bella (gas direct-vent)

Frequently asked questions
Will custom doors fit my Lennox Hearthstone / Montecito / Edge ST?
Yes — custom-sized to YOUR opening regardless of model. Send a photo + measurements; we confirm fit before production.
Are Lennox factory parts still available?
Limited — many older Lennox parts went out of stock after the 2018 HHT acquisition. Custom replacement doors are often the only practical solution for 15+ year old Lennox units.
Will my Lennox's mesh screen still work?
Yes — Brookfield coexists with factory mesh screens.
Does the factory Lennox frame stay in place?
Usually yes — replacement doors mount to the existing factory frame.
