Cavestone Fireplace Doors — Custom-Built USA

Cavestone fireplace doors are the bestseller in our catalog — handcrafted matte-black steel with cabinet-style swing doors, designed for masonry fireplaces where the customer wants an inside-fit installation that looks built-in and modern. Cavestone is unique in our lineup: it's the only door we sell that defaults to Inside Fit AND cabinet (twin-door swing) configuration. The result is a recessed, architectural look that disappears into the fireplace when the doors are open. 90% of Cavestone installs are Inside Fit on cleanly-built masonry openings.

Why choose Cavestone

  • Built in the USA by HearthCraft (the Cavestone-original manufacturer) — the manufacturer ExceptionalFire has partnered with for over a decade.
  • Custom-sized to your fireplace opening — no standard sizes that almost-fit. Every door is built to your tape-measure dimensions.
  • 5/8" overlap, ±1/16" tolerance — Cavestone is engineered for precision fit with clean tight reveal.
  • Hand-verified before production. Every order reviewed by our fireplace specialists — your photo, configurator selections, and measurements confirmed before the shop builds anything.
  • 5-year warranty on the frame, lifetime on the steel, with free shipping in the continental US.
  • Cavestone is our #1 inside-fit pick for premium masonry installations.

Available fits and configurations

Cavestone is available in Inside Fit (default) and Overlap Fit (available). Cavestone is best for masonry fireplaces with reasonably square openings — variance under 1/4" between top, middle, and bottom widths. Modern and transitional homes love the cabinet-style twin doors for the architectural feel.

Popular sizes: 36" × 30", 42" × 32", 48" × 30". Lead time: 14–21 business days standard.

How to measure for Cavestone

The measurement process is the same for every door — measure the FRONT opening of your fireplace at three points (width: top/middle/bottom; height: left/center/right) and use the smallest. See our step-by-step measuring guide for the full walkthrough including how to handle lintel bars, prefab quirks, and rough masonry.

Frequently asked questions

Is Cavestone good for masonry or prefab fireplaces?

Cavestone works best on masonry fireplaces. For prefab, see Brookfield or Rainbow.

What finishes does Cavestone come in?

27+ finishes across three tiers: free Powder Coat (matte black, textured black, ancient age, etc.), Artisan Premier (+$75–$150 — antique brass, brushed nickel, oil rubbed bronze), and Handcrafted (+$400+ — forged iron, burnished bronze, burnished copper).

How long does Cavestone take to ship?

14–21 business days standard. Most Cavestone configurations ship within 14–21 business days from order. Premium plated and handcrafted finishes run 4–5 weeks.

Can I order Cavestone with a mesh curtain?

Yes. Choose Twin Gate Mesh (most popular — swing-open like saloon doors), Single Panel Gate, Stainless Steel Mesh (+2–3 weeks lead), or No Mesh / Glass Only. Mesh sits behind the glass, so you can close glass for energy savings when the fireplace is cold and open glass + close mesh for spark protection during burns.

What's the warranty on Cavestone?

5-year warranty against manufacturing defects (frame welding, finish blistering, glass seal failure under normal use). Lifetime structural warranty on the steel frame itself. Standard exclusions: impact damage, abrasive cleaning damage.
