Oak Fireplace & Mantel Beams

Why choose solid wood?

A mantel beam sits directly above a working fire. That means it lives with heat cycling, humidity from the room, and the occasional direct warmth when someone's loaded the stove on a cold morning. MDF and veneered alternatives don't handle this well — the surface film lifts at corners and edges, and the substrate swells in ways that solid timber doesn't. We've seen a lot of veneered mantel shelves that look tired within a few years of going up, and there's no fixing them once the surface goes.

Solid oak moves as one piece. There's no core and facing working against each other. The grain, knots and colour variation are unique to each beam and they deepen over time rather than wearing away — the beam above your fireplace in ten years will have more character than the one you hung, not less. For our pine beams, the same logic holds: solid pine is wax-finished rather than veneered, so if it marks you re-wax it rather than replace it.

Types of mantel beams

Oak mantel beams: Available in seven wax finishes. Oak is naturally dense and handles the heat above a fireplace better than lighter timbers. Every beam has its own grain, knots and colour variation — we don't try to select for uniformity, because the character is the point. These are the beams that end up looking better above your fireplace than they did in the product photo.

Rustic pine mantel beams: Finished in light, medium or dark wax, with the natural knots and open grain that pine does well. Popular above log burners in country homes, farmhouse kitchens and cottages where the slightly rougher, more characterful timber suits the room. Good if you want a waxed finish you can touch up yourself over the years.

Floating mantel shelf: A slimmer profile using the same concealed fixings — the timber sits flush to the wall with nothing visible underneath. Works better in contemporary, Scandi and modern interiors where a chunky beam would feel too heavy for the room. Same solid timber, just a cleaner look above the fire.

How to choose the right mantel beam for your space

Beam or floating shelf comes down to the room and the fire. A fireplace beam is the chunkier, more traditional choice — it suits country, farmhouse and cottage interiors where you want something that looks like it's always been there. A floating shelf has a slimmer profile that works better in contemporary homes or above a modern inset stove where visual weight matters. Both use the same concealed fixings.

Oak or pine: oak is the right call for most situations. It's denser, holds up better near heat over time, and suits a wider range of rooms. Pine is a good choice when you want a waxed finish with more character and grain movement, when a painted finish matters, or when the room is already full of pine and oak would look out of place.

For stove clearances: above a log burner or wood-burning stove, there are minimum distances between the flue and any combustible material — and the beam counts. These vary by stove output and flue type, so check your stove manufacturer's guidelines or HETAS guidance for your specific installation. If you're not sure, get in touch with your measurements and we'll help you work it out before you order.

Mantel beam sizing guide

The short version: measure your fireplace opening and add 15–20cm to each side. A 90cm opening needs a 120–130cm beam. Profile choice — 10×10cm versus 15×10cm — depends on ceiling height and how much presence you want on the chimney breast. The deeper profile suits larger rooms and inglenook-style recesses; the 10cm depth works better in lower-ceilinged rooms where a chunkier beam would feel out of scale.

How to fit a mantel beam

Our beams use a keyhole bracket system. Steel keyhole plates are pre-fitted into the back of the beam; these slide over anchor bolts fixed into the wall. Once the beam is hanging, the fixings are completely hidden — no visible brackets, no exposed screws. Every beam ships with the keyhole plates already in place, plus the anchor bolts, wall plugs and drill bit you need for a standard solid masonry installation.

The process: mark the wall at the right height and centre point, drill and plug the anchor bolts into solid brick or block (minimum 60mm depth — not plasterboard alone), hang the beam onto the bolts and check for level, tighten. On solid masonry it takes about 30–45 minutes. The keyhole system means the beam can be removed and refitted cleanly if you redecorate — no adhesive, no permanent fixing.

If your chimney breast is dot-and-dab plasterboard over blockwork — common in 1980s and 1990s properties — the bolts need to reach the blockwork behind the plasterboard. That means longer fixings than the standard kit. Worth getting in touch before you order so we can confirm the right approach for your wall.

Every beam is made to order in our workshop in Hollywell Green, Halifax — a small team who've been building solid wood furniture for over a decade. Lead time is 1–2 weeks as standard. All timber is FSC certified and solid throughout — no MDF, no veneer. Standard lengths from 30cm to 200cm; if you need something outside that range or a specific profile, get in touch with your fireplace measurements and we'll confirm what's possible before you order. Every piece carries a lifetime structural guarantee.
