Berkeley Grey Oak

Berkeley Grey Oak is perfect for any room that requires a calming, antique look. Relaxing ashen hues blend with a meticulously hand-scraped texture in this extra rustic oak floor. Boards feature large knots, splits, and cracks characteristic of oak that's been underfoot for decades. Every intriguing and subtle tone has been accentuated by the smoking process, then finished with oil for a muted matt look. This textured engineered flooring is part of our Signature range, too.

These are the questions we get asked most often about our floors and their features.

Is Berkeley Grey Oak suitable for underfloor heating?

Yes – Berkeley Grey Oak is suitable for underfloor heating when fully stuck down.

How do I clean this oiled floor?

To clean this Berkeley floor, simply use our specially formulated cleaning liquid for oiled floors. Alternatively, use a well-wrung mop (water only). We do not recommend using a steam mop or any other solutions on our floors.

Does Berkeley flooring need to acclimatise before installing?

Yes – We recommend you let your Berkeley floor acclimatise for 3 to 4 days before installing. This needs to be in the same room that it will be installed in, and it needs to remain within the sealed packaging. The sealed packaging helps ensure the floor doesn’t warp with the change of temperature from different environments. Do not store the flooring outdoors, in an outbuilding, or anywhere with damp or condensation problems.

What condition should the subfloor be in?

The surface immediately beneath a Woodpecker natural wood floor must be in good structural condition, free from damp rot, fungal or insect infestation, and contaminating residues. It must be flat with uneven areas not exceeding 3mm over a 2m area. Naturally, the surface should be vacuumed and totally free of debris before fitting begins. Hot pipes should be well insulated to prevent localised hotspots, which can cause wood flooring to warp or shrink.

What expansion gaps does Berkeley flooring need?

As wood is a natural substance, it will expand and contract with changes in temperature and humidity. That’s why when a wood floor is fitted, expansion gaps need to be left wherever the boards meet a wall, structural support, stairs, breakfast bar, fireplace, central heating pipe…etc. Gaps must also be considered at doorways to allow for the differing expansion between rooms. Place spacers at regular intervals when fitting and then remove them before skirting boards, beading or trims are put in place. Allow a 2mm gap for every metre span of the floor with a minimum of 10-15mm gap regardless. For areas over 5m in width, extra provisions should be made for expansion.

How can Berkeley floors be installed?

Berkeley floors can be installed by being glued, secret nailed or floated.

What joints does Berkeley flooring have?

Berkeley flooring has tongue and groove joints.

Can I install Berkeley flooring in my bathroom?

We generally wouldn’t recommend using engineered flooring in a bathroom.

How thick is Berkeley flooring?

Berkeley flooring is 15mm thick which includes a 4mm real wood wear layer.

How much should I allow for wastage?

We generally recommend 10% wastage, however, this can be impacted by the room shape, laying style and other factors so always check with your installer first.

What does 'pack includes cut lengths' mean?

This means that at least one plank within your pack will be cut in half. This is intentional as it will help spread the joints out across your floor, thus helping prevent weakening. The other planks will be the same length.
