Our Fireplace Mantel Services
Cast stone mantels and plaster fireplace surrounds are elegant interior additions that we can customize to fit various architectural and style preferences. Explore the full extent of our fireplace mantel services here:

Custom Cast Stone Fireplace Mantels
Design your cast stone fireplace mantel to suit a modern, classic, minimalistic, or traditional style. We perform in-house fabrication, easing the customization process with improved quality-control and efficiency.

Custom Plaster Fireplace Surrounds
We use a specialized heat-resistant plaster containing vermiculite to create cast stone surrounds and mantel elements. For the hearth and the areas directly around the firebox, we recommend natural stone or tile, where temperatures are highest.

Fireplace Mantel Refacing and Upgrades
In addition to restorations, we specialize in custom cast stone and plaster mantel refacing and updating. We upgrade outdated surrounds with refined detailing without the cost of a full rebuild.

Fireplace Mantel Design Integration and 3D Visualization
Our team creates 3D renderings and conceptual layouts, allowing you to see your fireplace design in the context of a specific room before it’s even built.

Cast Stone, Limestone, And Wood Mantels
Quarrying limestone gets you solid natural stone, though every piece is heavy, the colour and veining shift from slab to slab, and cutting and setting it takes more labour on site. We shape your cast stone mantel in a mould instead, setting the profile, size and colour before production starts, so it weighs less than limestone, installs more easily, and usually costs less while keeping that same natural stone look.
We build a cast stone fireplace surround as one design, with the legs, shelf, and overmantel together, instead of the wood shelf many Toronto fireplace mantels use in oak, pine, or maple. A wood shelf on its own gives you a top ledge and little else, and it still has to sit a set distance above the firebox, which limits how low and how deep it can go.
If weight is your main concern, a carved plaster surround gives you the lighter option. See custom plaster fireplace surrounds above.
Mantels We Build
Every custom fireplace mantel we create starts with your room, your ceiling height and your style. These three cast stone projects show the range, from clean modern lines to full traditional ornament, and each project page has more photos of the finished work.

How A Cast Stone Mantel Is Made
Building a cast stone fireplace mantel for your Toronto home takes five steps, and nothing gets built until you approve the design. Here’s what happens from your first visit with our team to the final walkthrough.
Site Visit and Measurements
We visit your property, measure the opening, wall width and ceiling height, and check the existing fireplace.
Finish Sample
You review a cast stone sample for colour, texture and finish, and sign off on it before we move forward with the design.
3D Layout
When your project calls for it, a 3D layout shows the mantel in your room so you can judge its scale.
Fabrication in the Shop
After you approve the design, we make the mantel in our own facility. You get the timeframe before production begins.
Installation
Our team sets the mantel at your property. We can include patching and painting where needed, and we finish with a final walkthrough.
