As a home improvement professional with over 10 years of experience renovating fireplaces, I‘m often asked if it‘s possible for homeowners to remove an existing brick hearth themselves. The answer is yes – with proper planning, safety precautions, and the right tools, DIY hearth removal is totally achievable.
In this comprehensive guide, I‘ll share everything I‘ve learned from removing countless hearths, including step-by-step instructions, insider tips, relevant codes, and answers to frequently asked questions. My goal is to fully equip you with the expertise I‘ve gained so you can take on this project confidently and safely.
Big Picture Overview
Before we dig in, let‘s look at the key steps involved:
- Turning off gas lines and electricity
- Bracing the surrounding structure
- Chiseling out old mortar
- Carefully prying up bricks one by one
- Disposing of rubble properly
- Cleaning and prepping the area for new install
Smaller hearths can potentially be DIY, but larger or intricately designed ones often require hiring a mason for all or part of the demolition. I‘ll offer tips to help you decide if it‘s best to call in a pro.
Safety is also paramount when doing any demolition. Be sure to wear protective gear and take precautions.
Alright, let‘s get into the details!
Step-by-Step Removal Process
Follow these steps in order when taking out your brick hearth:
Shut Off Gas and Electricity
The first step is always to shut off the gas line and disconnect it from the fireplace. Cap it off temporarily for safety. Even if you don‘t plan to reuse the fireplace, you don‘t want any open gas lines while demolishing!
Also turn off any nearby electrical lines to be safe. Use a circuit tester to double check. Safety first!
Check for Asbestos
While less common in newer homes, asbestos fibers were frequently used in cement and flooring between the 1940s-1980s. Inhaling particles can cause lung disease.
Before demolishing, have a sample of materials tested by a lab to rule out asbestos. If found, hire an abatement team to remove safely.
Support Surrounding Structure
Once utilities are off, use 2×4 lumber to create temporary supports around the fireplace opening. This stabilizes the structure so the front doesn‘t collapse when you remove the hearth.
I recommend placing vertical 2×4 posts on each side of the fireplace secured to the ceiling. Then run a 2×4 across the top front to distribute weight.
Remove Facing Materials
Carefully detach any stone, tile, brick or other facing materials from the surface of the hearth first. Pry off gently with a flat bar if needed.
Also remove the mantle at this time if possible. Try to pry it off in one piece to preserve it if desired.
Chisel Out Mortar
Now comes the tough part – chiseling out all the old mortar so the bricks are loose. Use a masonry chisel and 5 lb sledge hammer.
Hold the chisel at a 45 degree angle and tap firmly to score the mortar joints around the perimeter first. Be sure to wear safety goggles – bits of mortar will fly!
Once scored, start chipping away mortar completely until an entire layer of bricks is loose. Repeat until all vertical and horizontal mortar is removed.
Remove Bricks
After mortar is cleared out, you can start actually removing bricks. Insert a small pry bar under the edge of a loose brick and gently pry/lift up and out.
Work slowly and methodically. Stack removed bricks neatly to reuse or dispose of later. Don‘t be afraid to take breaks – this process is physically demanding!
Clear Debris
Use a shovel to clear away any loose material, rubble, or debris left behind after you‘ve removed the bricks. Sweep the area clean.
Consider renting a mini skid steer loader to remove heavy debris quickly if doing a large hearth. Well worth the rental fee!
Smooth and Clean Area
Once cleared of debris, use a wire brush and shop vac to clean up remaining dust and particles. You want a smooth surface for your new hearth installation.
If reusing the fireplace, inspect the interior for cracks or damage. Seal any gaps with high-heat caulk.
Pro Tips and Tricks
I‘ve picked up a few tips over the years that make hearth removal much easier:
-
Spray bricks with water to reduce dust while chiseling
-
Use a 5 lb drilling hammer for quick mortar removal
-
Occasionally run a rebar through weep holes to expedite prying up stubborn bricks
-
Change drill bits frequently to avoid wear and breakage
-
Place plywood under knees for comfort during extended chisel work
-
Take before photos from multiple angles – invaluable for rebuilding later!
Safety Precautions
Hearth removal involves demolition, dust, and debris. Protect yourself by always wearing:
-
Safety goggles/glasses – protects eyes from flying chips
-
N95 dust mask – reduces inhalation of harmful silica dust
-
Ear plugs or muffs – protects hearing from loud hammering
-
Gloves – Leather gloves prevent blisters and keep hands safe
-
Long sleeve shirt & pants – Prevents skin irritation and injuries
-
Boots – Steel toes and shanks guard feet from dropped bricks
And of course, demolish carefully and take regular breaks to prevent overexertion or injury!
What Tools Will You Need?
Removing a hearth takes time and some specialized equipment. Here‘s what I recommend having on hand:
For Demolition:
- Rotary or Demolition Hammer Drill – for drilling into mortar
- Masonry drill bits – carbide tip for durability
- Cold chisels – 2" width optimal, get several since they dull
- 5 lb drilling hammer or sledge hammer
- Small 18" pry bar
- Goggles, gloves, mask as mentioned
For Cleanup:
- Dustpan and shop vac – for collecting brick dust
- Wire brush – for smoothing mortar remnants
- Shovel and/or skid loader – removing rubble
For Bracing:
- 2×4 lumber – for supporting structure temporarily
For Debris Removal:
- Wheelbarrow and/or dumpster – for hauling away rubble
Having the right tools makes the demolition process much smoother!
How to Dispose of Old Brick and Mortar
Once removed, you‘ll have a pile of old brick, mortar chunks, and other rubble to deal with. Here are some smart ways to dispose:
-
List usable antique bricks for free on Craigslist or Facebook for reuse. Lots of demand!
-
Haul rubble in a truck or trailer to a construction debris landfill or recycling center if available. Cost is usually $50-$150.
-
Rent a dumpster for 1-2 weeks while demolishing. Cost ranges from $300-$800 depending on size.
-
Use rubble to fill holes, make drainage, create garden beds around the property. Repurpose!
Check your local regulations for proper disposal procedures. Never attempt to burn mortar or bricks – the materials are not safe to inhale when burned.
Repurposing the Space
Once that dated brick hearth is out of there, what should you do with the empty cavity where it once sat? Here are some fun ideas I‘ve helped clients implement:
-
Build a new, smaller hearth and install a modern gas fireplace insert
-
Construct a stone or brick raised platform for potted plants and decor
-
Install a custom bench or window seat for cozy seating
-
Build out cabinetry or shelving for storage, books, collectibles
-
Lay a tile floor and turn into a coffee bar area
-
Add a wall-mounted TV and make a sleek media nook
Get creative with this new blank canvas – the options are endless!
Cost Comparison: DIY vs Professional Removal
Is it worth tackling hearth removal as a DIY project to save money? In most cases yes, but here‘s a cost breakdown:

Inspect Fireplace Integrity Before Removal
Once the hearth is out, examine the fireplace structure closely to determine whether it‘s suitable for rebuilding. Look for:
-
Large cracks in walls or smoke chamber
-
Broken, deteriorating, or missing bricks
-
Mortar damage, gaps, or instable joints
-
Rust, holes or other damage in metal damper
-
Soot marks or creosote buildup indicating poor draft
If the inspection reveals serious issues, repairs may not be worth the trouble vs fully rebuilding the fireplace. Consult a mason for an expert assessment.
Hearth Dimension Regulations Per Code
If planning to build a new hearth after removal, be sure to follow fire code regulations for proper sizing. Requirements include:
-
Extending at least 16" in front of fireplace opening
-
Extending at least 8" beyond each side of opening
-
Made of noncombustible material like brick or stone
