Installation Options
Installation (Underlay)
1. Glue or screw down your cement coated overlay boards to a flat level surface
2. Install your heating pipe into the pre-set grooves, either Pert-Al-Pert or Ultra Flexible EVOH
3. Roll-out the breathable underlay across the entire surface area, for fast and simple installation use Rapid Spray to securely fix in place
4. Then lay your engineered wood, laminate or real wood flooring onto the underlay as a floating floor
5. Please ensure you leave a 10mm perimeter gap between the wood and walls to allow for expansion

We recommend that all floors are either floated, glued or nailed/screwed down. For a full outline for installation of Oak Flooring, please visit our dedicated Installation Guide.
Storage – Flat and Dry Only
As wood is a natural product it is important that it is stored correctly. We recommend that your new products are stored flat and in a dry area. We recommend that all packaging is kept on the products or removed for inspection and then re applied for storage (please note that returns need to be in the original packaging, unopened). Again, as wood is a natural product it is susceptible to changes in each room’s atmosphere and as such, please be mindful of this and take care to avoid damp areas or newly plastered rooms etc. Ideally, storage will be in the same room as installation.
Flooring Maintenance – Care Guide
You’ll know when your wood floor needs cleaning, as the dust and dirt is visible (unlike carpeting that hides its dirt below the surface) a simple vacuum, sweep or dry mop is all that’s needed to clean day-to-day dust and loose dirt.
Dirt and grit act like sandpaper on the surface of a wood floor. As 80% of dirt comes from outside, place sturdy doormats and rugs at entry points and use furniture pads under chair legs and heavy furniture.
Consider a ‘no-high-heels’ policy and be aware of pets’ bad habits and scratching. Never place potted plants directly on a wood floor. For a thorough and regular (every couple of months) ‘refresher’ clean, use a recommended after-care cleaning/maintenance product such as Wash & Care and you’ll bring a new lease of life to your floor.

What to Expect
Each postcode is allocated to a zone & depending upon the zone in which a postcode sits, will be how much delivery is. Each pallet delivered, takes 2 working days from order to delivery. For further shipping costs, please see our Shipping Cost page

Each box of flooring purchased has a weight, to which if you require 1 boxes of flooring, the average weight per box is 27kg (depending on the thickness and type of product purchased). ½ Boxes will be delivered via our Carrier Parcel Force Worldwide & you will be provided with a Tracking ID & delivery time frame via text & email.

If you were to order more than 2 boxes, the cost for shipping will be based on a full pallet rate. This will be the same for 3 boxes as it is for 30 boxes. Anything over and above 1000kg will incur a two-pallet charge rate.
Because we use an external courier network for our nationwide deliveries, it is important that you arrange for somebody to be present on the day of delivery to sign for the goods being delivered and accept your new oak floor as being in top condition.

Typically, couriers are only insured to deliver ‘kerbside’ (meaning off the side of their vehicle). Having said this, some drivers will help to carry the cartons of flooring into houses and garages but we cannot guarantee this will be the case with every driver, and we cannot ask them to do this. Help and assistance for the driver must be provided on site for delivery, not just to help carry the cartons of flooring into a dry and safe storage area (remember some weigh as much as 38kg) but also to actually sign for the delivery and confirm receipt.
It is vital that your new oak floor is immediately stored in a dry and sheltered area. If it is raining and the flooring is left outside, it will be ruined so it is important to get it inside to safety as quickly as possible. Even if the weather is dry, there is always a risk of your flooring being stolen if it’s left outside.
