How much does it cost to reface a fireplace with natural stone veneer in Ottawa?

A natural stone veneer fireplace refacing project in Ottawa typically costs $3,500 to $8,500 for materials and labour, depending on the size of the fireplace, the type of stone selected, the complexity of the existing surround, and whether structural prep work is needed.

Here's why the cost varies so widely in Ottawa's market. A modest fireplace refacing — say, facing the firebox surround and a simple wall section in a single colour of stacked stone — might run $3,500 to $5,000 installed. A larger project covering both the fireplace surround and the entire wall behind it, using premium stone varieties like real slate, granite, or reclaimed brick veneer, can easily reach $6,500 to $8,500 or more. Labour accounts for 40 to 50 percent of the total cost because stone installation is meticulous work — each piece must be cut, fitted, and mortared to create a finished appearance that will last decades in your home.

The substrate matters significantly. If your existing fireplace has a solid, sound masonry or drywall base, installation is straightforward. If the existing surface is damaged, uneven, or needs repair before stone can be installed, preparation costs add $500 to $1,500. Likewise, if you're removing old tile, brick, or plaster first, add another $300 to $800 in demolition and cleanup labour.

Stone selection dramatically impacts your budget. Manufactured stone veneer — engineered to look like natural stone but lighter and faster to install — runs $4 to $12 per square foot installed and is the most economical choice, typically falling into the $3,500 to $5,500 range for a standard surround. Real slate or granite veneer costs $8 to $20 per square foot installed and pushes projects toward the $6,000 to $8,500 or higher range. Reclaimed or antique brick veneer is premium material that can exceed $10 per square foot installed. Stack stone, thin ledge stone, and tumbled finishes are popular in Ottawa homes because they create visual texture and complement modern and traditional aesthetic styles equally well.

One practical consideration specific to Ottawa: if your fireplace has an active wood-burning or gas insert, the stone installer must maintain proper clearances to heat sources — typically 6 to 8 inches of non-combustible material or proper air space around the firebox opening. This is not just a safety code requirement; it's essential for preventing heat damage to the stone and surrounding materials in your home. A professional stone installer familiar with WETT and OBC requirements will know these clearances, but always confirm this before work begins.

Timing matters in Ottawa's climate. Stone installation requires consistent temperatures above 5 degrees Celsius for adhesive and grout to cure properly, which means fireplace refacing work is best scheduled for late spring (May), summer (June through August), or early fall (September and early October). If you're planning a stone refacing, booking early in spring ensures contractors have availability and weather will cooperate with proper curing times.

Get three written quotes that specify the exact stone type and colour, total square footage to be covered, whether demolition of existing finishes is included, warranty on labour and materials, timeline, and cleanup responsibility. Many contractors will offer a small selection of stone samples so you can see colour, texture, and finish in your actual lighting before committing.
