How To Frame a Raised Fireplace Hearth

A raised fireplace hearth adds a touch of elegance and functionality to any fireplace design. It elevates the firebox and hearth, creating a focal point and providing a more comfortable seating arrangement. Framing a raised hearth involves building a sturdy platform that can safely support the weight of the fireplace and its accessories. This guide will provide a step-by-step process for framing a raised fireplace hearth, ensuring a secure and aesthetically pleasing result.

1. Planning and Preparation

Before starting the construction, careful planning and preparation are crucial.

Determine the desired height and dimensions. Consider the overall fireplace design and the height of the seating arrangement. Aim for a comfortable height for accessing the fireplace and a width that complements the fireplace opening.
Select the appropriate materials. Use pressure-treated lumber for the framing, as it resists moisture and decay. Choose fire-resistant drywall or tile for the hearth surface.
Obtain necessary permits. Depending on local building codes, permits may be required for structural changes. Check with the local building department for specific requirements.
Prepare the work area. Clear the area around the fireplace and protect surrounding surfaces from dust and debris.

2. Framing the Hearth Platform

The framing forms the sturdy base for the hearth.

Build the frame. Using pressure-treated lumber, create a rectangular frame that matches the desired dimensions of the hearth. Cut the lumber to size and secure the pieces with screws or nails. Make sure the frame is level and aligned with the fireplace opening.
Add support beams. To ensure structural integrity, install additional beams running across the width of the frame. These beams should be securely attached to the frame using joist hangers or other appropriate fasteners.
Install blocking. To provide extra support and prevent movement, install blocking between the support beams. This blocking should be spaced evenly along the length of the frame.

3. Creating the Hearth Surface

The hearth surface requires a material that is both sturdy and resistant to heat.

Install plywood subfloor. Cover the framing with a layer of plywood. This will serve as a base for the final hearth surface.
Add a moisture barrier. Apply a moisture barrier, such as a sheet of polyethylene, to the plywood subfloor. This helps prevent moisture from damaging the framing and hearth.
Install the hearth surface. Attach the chosen hearth surface material. Fire-resistant drywall is a cost-effective option, while tile provides a more elegant and durable surface. Secure the drywall using drywall screws, or apply tile adhesive for tile installation.

4. Finishing Touches

Finishing touches ensure a smooth and safe hearth surface.

Apply sealant. Seal the edges of the hearth surface with a sealant to prevent moisture from seeping in.
Add decorative trim. Consider adding decorative trim around the perimeter of the hearth to enhance its aesthetic appeal.
Install a fire screen. Protect the hearth surface and surrounding areas from sparks and debris with a fire screen.

Remember to always follow local building codes and safety regulations when framing a raised fireplace hearth. Consult with a qualified professional for any complex structural issues.
