Wood Floor Sanding: Methods, Prices & Finishes

The most suitable sanding method depends on the construction of the floor, the amount of sound timber remaining, previous sanding and the condition of its coating. On suitable floors, orbital or multi-disc machines can be useful for controlled abrasion, blending and fine preparation. Belt sanders may be appropriate when an older coating must be removed more substantially or the timber needs careful levelling. The abrasives and sequence are chosen after assessing the actual floor; neither machine type is automatically best for every job.

Customers have described Stefan using an orbital sander on previously sanded wood floors. That practical example illustrates why assessing the remaining timber matters before choosing a method. Professional extraction helps control airborne dust, but it cannot guarantee a completely dustless site.

Lacquer (also called varnish), oil and hardwax oil protect timber in different ways, and suitability depends on the wood, room use, existing coatings and maintenance preferences. The published £35/m² starting price covers sanding only; application of the chosen protective finish is quoted separately. The coating, preparation required and number of coats are agreed as part of the quotation.

A published customer review describes Bona Traffic being used for a maple floor after sanding. This is an example of an actual reviewed project, not a promise that the same product is suitable for every floor. For advice on finishes see wood floor sealing and our oil or lacquer guide. Drying and full curing are different: walking, furniture and rug timings depend on the selected manufacturer's product instructions and site conditions.

There is no universal number. The safe number of resands depends on original board thickness, remaining wear layer, previous treatments, fixing positions and the floor's condition. Engineered wood can have a thin real-wood surface, which may make further sanding unsuitable. We assess the floor and may recommend compatible maintenance rather than another resand when preserving the timber is the better approach.

The process begins with a floor assessment: we look at the timber type, stability, surface wear, old coatings and any previous sanding. We then agree the preparation and scope. Where suitable, the floor is sanded using appropriate abrasive stages and careful edge work before application of the selected lacquer, oil or hardwax oil finish. Any repairs, gap filling or staining are discussed separately when needed. Our work plan and quotation specify what is included.

Many original pine floorboards in London period properties and suitable solid oak or hardwood floors can be sanded. Results depend on the amount of sound wood left, board movement, protruding fixings, splits and the history of previous sanding. We check whether boards need securing or repairing before proposing sanding. We do not promise that every uneven board or deep mark can be removed.

Sometimes. Engineered wood has a real-wood surface over a core, but its wear-layer thickness varies. Thin veneers, factory finishes, previous sanding and damage can make further sanding unsuitable. We inspect the floor and consider the manufacturer's instructions where available. Laminate floors do not have the sandable real-timber surface required for this process.

Sound solid parquet, herringbone and other wooden block floors may be suitable for sanding and refinishing. Loose blocks, failed adhesive, gaps, historic repairs and changes in timber grain direction need special attention. If parquet blocks are missing, moving or badly damaged, review our parquet floor restoration service first. It covers the repair-related intent without creating a competing parquet sanding page.

No. Professional sanding with dust extraction is designed to minimise dust, not eliminate it altogether. Some dust may still be produced around edges, corners and preparation work. We explain practical precautions for furniture, adjacent rooms and access before starting. We do not claim that sanding produces no dust or disruption, as some dust and normal site disturbance may remain.

Preparation varies with the room and condition of the boards. We discuss moving furniture, removing rugs, access arrangements, existing flooring or coatings, pets, ventilation and other occupied-room considerations. Loose boards, protruding nails or damaged parquet may need attention before sanding. Items such as furniture removal or extensive repairs are only included when expressly agreed in the quotation.

A suitable finish depends on the timber, the look you prefer, foot traffic and how the surface will be maintained. Lacquer or varnish provides a protective surface coating in a choice of sheen levels. Oil and hardwax oil systems can give a different appearance and repair or maintenance approach. Compatibility with old treatments matters. We discuss wood floor sealing and, where a colour change is desired, optional floor staining.

Sanding can improve many shallow scratches, a worn coating and some surface discolouration. Deep dents, staining that penetrates the timber, moisture-related damage and defects in the floor structure may remain. It is important to distinguish cosmetic refinishing from wood floor repairs or replacement of severely damaged sections. We explain the likely limitations when assessing the floor.

Our published starting rate is from £35 per m² for sanding only. Lacquer, oil, hardwax oil and other protective finishing are quoted separately. It is a guide rather than a fixed price for every property. The quotation depends on floor area, number of rooms, existing coatings, condition, access, repairs and the chosen finish. Extra gap filling, staining or repairs may affect the scope. See the wood flooring price guide for more information about prices and quotations. We do not compare competitors' headline rates without checking what preparation and coats are included.

The time needed varies by area, timber condition, repairs, sanding stages and the finishing product. Surface drying and full curing are not the same thing. A coating may permit limited use before heavy furniture, rugs or routine cleaning are appropriate. The manufacturer’s instructions and on-site conditions determine the guidance for walking on the floor and returning furniture. We explain the timetable for the agreed finish.

Suitable wooden steps, landings and narrow hallways can be assessed for sanding and refinishing. Work around stair nosings, edges, spindles or existing coatings can require extra preparation and manual detail work. Staircases are assessed separately because a simple room-area calculation may not describe the labour involved.

A compatible maintenance treatment may be preferable if the existing timber and coating are sound and the wear is superficial. Full sanding is more appropriate when the finish is sufficiently worn or surface damage requires removal of a controlled layer of wood. See floor care and maintenance for less invasive options. A short description of the floor and photographs can help identify what assessment is needed.

We consider suitable timber floors in offices and other commercial environments. The choice of finish, foot traffic, access and scheduling must be assessed for each project. Commercial requirements and any additional preparation should be agreed rather than assumed. Read about our commercial flooring services or request a project quotation.

Follow the curing and cleaning advice given for the exact lacquer, oil or hardwax oil used. Avoid standing water, remove abrasive grit and use cleaners compatible with the new finish. Rugs, furniture and intensive use should return only when the finish is sufficiently cured. For longer-term upkeep, see wood floor maintenance in London.

If sufficient sound timber remains, sanding and refinishing may preserve much of an original floor. When boards are severely damaged, unstable or too thin, targeted repairs, parquet restoration or replacement may be more appropriate. The right recommendation depends on assessment, not a blanket promise that every old floor can be restored.
