Project Overview
This Northwood property had a new hardwood floor installed and sanded as a complete project. The client had chosen unfinished solid oak boards for the main reception room, wanting a traditional solid wood floor that could be sanded and finished on site to their exact specification. The installation, on-site sanding, and oil finish were all handled as a single project, from subfloor preparation through to final coat.
The Challenge
Installing solid hardwood floors requires more subfloor preparation and care than engineered boards. Solid wood is more sensitive to moisture and will move significantly if the subfloor is not completely dry, the room is not at a stable temperature and humidity, or the boards are not given sufficient time to acclimatise before fitting. Getting the subfloor condition right is not optional with solid wood. Skipping or rushing these steps is the most common cause of problems after installation. The room in this property also had a bay window area that required careful planning to keep the floor pattern consistent around the projection without leaving awkward cut pieces in the most visible part of the room.
Our Approach
Subfloor Preparation
The subfloor was thoroughly checked for levelness, moisture content, and structural soundness. A plywood overlay was installed to provide a stable, flat base for the hardwood boards. This is standard practice when laying solid wood over an older concrete or suspended timber subfloor, as it provides a consistent nailing or stapling surface and helps buffer any residual moisture variation in the subfloor below.
Acclimatisation
The solid oak boards were delivered to the property and left in the room where they would be fitted for the full manufacturer-recommended acclimatisation period. This is a step we take seriously, as the amount of movement in a solid wood floor post-installation is directly related to how well the boards were acclimatised before fitting.
Board Installation
The boards were installed using a secret-nail method, working from the straightest wall and using a board straightener to keep each run tight and aligned. The bay window area was planned from the outset to keep the board layout symmetrical and avoid cuts at the focal points of the room.
On-Site Sanding and Finishing
Once installed and allowed to settle, the floor was sanded through a multi-stage programme starting with a levelling grit and finishing with a fine grit ready for the oil application. A natural hardwax oil was applied in two coats, buffed between each, giving the oak a warm, open-grained finish that suits the character of the room well.
The Result
The finished floor is a significant improvement to the reception room. The solid oak has a warmth and depth that suits the property, the grain reads well across the space, and the oil finish gives good protection without adding any artificial sheen. The client was particularly pleased with the bay window layout, which came out cleanly and consistently. Solid hardwood floor installation and sanding in the Northwood area typically costs from around £50 to £80 per square metre for supply, fit, sand, and finish, depending on the timber species and the finish specification.
Frequently Asked Questions
How long does solid wood need to acclimatise before fitting?
The standard recommendation is a minimum of three to five days in the room where the floor will be fitted, with the boards stacked so air can circulate around them. In older properties with older heating systems or in winter months when heating cycles are more pronounced, a longer acclimatisation period is advisable. We always recommend erring on the longer side rather than rushing this step.
Can a solid wood floor be installed in a kitchen or bathroom?
We generally advise against solid wood in kitchens and bathrooms due to the exposure to moisture. Engineered wood is a far better choice in these rooms and can be specified to look identical to solid wood from above. Solid wood is best used in rooms where moisture and temperature are well controlled, such as living rooms and bedrooms.
How many times can a solid hardwood floor be sanded in its lifetime?
This depends on the thickness of the boards and the amount removed with each sand. A 20mm solid oak board, for example, can typically be sanded four to six times over its lifetime before the tongue is approached. This makes solid hardwood one of the most long-lasting flooring options available, with a potential lifespan of many decades when maintained correctly.
