Solid Wood Flooring Installation: What Buyers Need to Know

Installation requirements should influence which floor you buy. A beautiful board is not the right purchase if its fitting requirements do not suit your room or subfloor. Before ordering from our solid wood flooring range, use this guide to understand the questions worth answering first.

Assess the subfloor

Identify what the floor will be installed over and make sure it is suitable for the intended method. The surface needs appropriate preparation, and moisture conditions must be within the flooring manufacturer's requirements. Problems beneath a timber floor can affect the finished installation, so preparation should never be treated as an afterthought.

Concrete and screeded subfloors

A concrete or screeded base may look dry at the surface while still containing moisture. Appropriate testing and any required moisture-control system should be dealt with before timber is installed. The base also needs to meet the flooring manufacturer's flatness and strength requirements. Do not expect adhesive or the boards themselves to correct a badly uneven floor.

Timber subfloors

Existing timber bases should be stable, secure and suitable for the chosen fixing method. Loose boards, excessive movement or damaged areas should be addressed first. Consider ventilation and any signs of damp as part of the assessment rather than simply covering the existing floor.

Allow for natural movement

Wood is a natural material and responds to environmental conditions. Installation instructions normally address expansion provision, perimeter details and room conditions. Follow the exact guidance supplied for your flooring rather than applying a single generic expansion measurement to every product.

Expansion planning includes more than the four walls. Door frames, columns, hearths, pipework and other fixed objects can affect the detail. Large or connected spaces may also require transitions depending on the flooring system.

Acclimatisation

Some timber products require acclimatisation before installation. The correct process and duration depend on the manufacturer and product, so check this before booking the fitter. Keeping boards in unsuitable conditions simply because they are 'acclimatising' can be counterproductive.

Store the flooring correctly

Follow the manufacturer's storage instructions and keep the packs protected from unsuitable moisture or temperature conditions. A damp garage or building site may be very different from the finished room. Coordinate delivery, room preparation and fitting so the floor is not left in poor conditions while other wet trades are still working.

Choose the installation method before ordering accessories

Adhesives, profiles and other installation materials should match the flooring, subfloor and fitting method. Browse our wood flooring accessories after confirming what your chosen product requires.

Bonded and mechanically fixed installations

Solid timber may be bonded or mechanically fixed depending on the board and substrate. Do not assume that a floating method used for another type of flooring is appropriate. The correct system should come from the product instructions and the condition of the subfloor.

Plan thresholds and adjoining floors

Consider doors, transitions and changes in floor height before work begins. The thickness of the boards and any preparation layers can affect finished levels. Planning these details early can prevent awkward transitions after the main floor has been laid.

Measure door clearances and consider how skirting or other edge details will finish the expansion space. If the new floor meets tile, carpet or another timber floor, select an appropriate transition profile before installation reaches that point.

Decide the board direction before fitting

Board direction influences both appearance and cutting. Long straight runs can emphasise room proportions, while connected spaces may need a compromise that creates sensible transitions. Set out the first rows carefully because a small error at the beginning can become more obvious across the room.

Underfloor heating needs an early decision

If the property has underfloor heating, verify compatibility before buying. Do not assume every solid timber product can be installed over every system. Where the project calls for greater dimensional stability, compare engineered wood flooring as part of the decision.

Ordering enough material

Calculate the net floor area, then allow for the cutting and wastage appropriate to the room and layout. Check the exact pack coverage of the chosen product. Ordering all required packs together can also reduce the risk of needing a later top-up when the installation is underway.

Why wastage varies

A simple rectangular room generally creates fewer awkward cuts than a room with bays, chimney breasts, alcoves and several doorways. Board dimensions and the intended layout also affect usable offcuts. Ask the installer to confirm the allowance rather than applying one percentage to every project.

Check the room before installation day

Complete dusty or wet building work first where practical. Confirm the room conditions are within the flooring manufacturer's requirements, the subfloor preparation is complete and all necessary trims and fitting materials are available. Removing skirting, adjusting doors or preparing thresholds at the last minute can slow the job unnecessarily.

Products to compare

Options such as Atkinson & Kirby Hatfield Oak Hand Finished Lacquered Solid Wood Flooring and Atkinson & Kirby Burton Oak Brushed UV Oil Solid Wood Flooring give buyers different finishes to consider. Always use the individual product information when planning installation.

After installation

Follow the manufacturer's guidance before replacing heavy furniture or beginning routine cleaning. Use suitable furniture pads and keep the floor free from grit. Retain the product and finish information because it will help you select compatible cleaning and maintenance products later.

Installation questions buyers often ask

Can I fit solid wood flooring myself?

That depends on your experience, the product and installation method. If you are unsure about moisture testing, subfloor preparation or fitting requirements, professional installation is worth considering.

Do I need underlay?

Not every solid wood installation uses the same build-up. Follow the chosen product's installation instructions rather than automatically purchasing underlay.

When should I choose my accessories?

Choose them once you know the exact flooring, subfloor and installation method. That helps avoid buying incompatible preparation or finishing products.

Do I need to remove skirting boards?

That depends on the intended edge detail and installation. Some projects remove and refit skirting, while others use an appropriate finishing profile. Plan this before fitting so the required expansion provision can be finished neatly.

Can solid wood be installed directly over concrete?

Only using a method approved for the exact flooring and after the concrete or screed has been properly assessed and prepared. Moisture, flatness and the specified fixing system all need to be considered.

Should the flooring be installed before kitchen units?

The correct sequence depends on the project and flooring manufacturer's instructions. Discuss fixed cabinetry, expansion requirements and appliance access with the installer before deciding.
