Walk into a flooring showroom and the two ranges look almost identical. Both are oak, both are 15 to 20mm thick, and the price difference can be a third. The difference is inside the board.
We lay both across Gloucester and Gloucestershire. This is what actually matters when you are choosing.
How the two boards are made
Engineered flooring is a real wood top layer bonded to a plywood or multi layer core. The top layer is typically 3 to 6mm of oak, sometimes more. The core is stable because the layers are glued with the grain running in alternating directions.
Solid wood flooring is one piece of timber, usually 18 to 21mm thick, cut from a single board. It is the traditional option and it can be sanded and refinished many times over its life.
Stability and movement
Timber moves with the seasons, expanding and contracting as humidity changes. A solid board moves as one piece, which is why solid floors need wide expansion gaps and are risky over underfloor heating.
An engineered board moves far less because the cross layered core resists it. That is why engineered flooring is the standard choice in modern builds with large open plan rooms, wide plank sizes and consistent heating.
Underfloor heating
Engineered flooring works well over underfloor heating, provided it is laid correctly and the heating is commissioned gradually. The key is the core, which stays flat as it warms.
Solid wood can be used over underfloor heating in some situations, but it is a compromise. The boards can cup, gap or check, and many manufacturers will not warranty solid timber over a heated screed. If you have underfloor heating, engineered is the safer answer.
Cost and longevity
Engineered flooring is typically 20 to 40 per cent cheaper than solid for a comparable oak look. A solid board can be sanded back five or six times over decades, while an engineered board with a 4mm wear layer can usually be refinished two or three times.
Over a twenty year horizon in a family home, both work out similar value. In a hallway or a rental property that takes a beating, solid has the edge. In a kitchen, an engineered board with a good wear layer is more practical.
Where each one belongs
Solid wood suits period properties, hallways, living rooms and anywhere you want one continuous timber floor that will be sanded and refinished over the decades. It sits well in the older houses we work on around Painswick, Tewkesbury and the Cotswold villages.
Engineered suits kitchens, open plan spaces, basements, modern builds, flats and anywhere with underfloor heating. It is also the practical choice above a concrete slab, which is most new build ground floors in Gloucester.
What affects the finish more than the board
How a floor is laid matters more than which board you buy. Subfloor preparation, moisture testing, acclimatising the boards in the room for a few days, a proper underlay and correct expansion gaps decide whether the floor stays flat and silent for twenty years.
That is the part we check on every job. A perfect board laid on a subfloor that is 4mm out of level will creak within a year, and no warranty covers the installation if it was never flat to begin with.
Finishing, oil or lacquer
Oiled floors look warm and natural and can be spot repaired with a cloth and a little oil. They need re oiling every year or two in a busy area, which takes an afternoon.
Lacquered floors are sealed with a hard wearing film and need almost nothing beyond damp mopping. They are the better choice for a busy family kitchen or hallway. If the lacquer is damaged it usually needs a full sand back to repair.
Which we recommend
For most Gloucestershire homes, an engineered oak board in a 180 to 220mm plank, laid over the correct underlay with the subfloor tested and prepared, is the best balance of stability, price and appearance. It handles the heating, the door thresholds and the British climate.
For a period property where the floor is the feature, or where you want a floor you can sand back for the next fifty years, solid oak is still the right answer.
Getting your floor laid properly
We hang doors and lay engineered and solid wood flooring across Gloucester and Gloucestershire, always after checking the subfloor for level, moisture and soundness, and always with the boards acclimatised in the room first.
See our doors and floors service for how we work, or request a free quote and we will measure the area, check the subfloor and price it properly.
How the floor meets the rest of the house
The joins decide whether a new floor looks considered or bolted on. Doors usually need the bottom taken off and resealing once a thicker floor is laid, and skirting that was fitted to a carpet height rarely sits right afterwards.
Thresholds matter too. Where wood meets tile in a kitchen passage, or meets an existing floor in a hallway, the transition has to be planned rather than improvised on the day. On stairs, the first riser or a matching nosing hides the change of level cleanly. We work all of this out at survey so the boards are cut once, in the right direction, with the grain running the way you want it.
Humidity, heating and the British climate
Gloucestershire winters are damp and centrally heated homes are dry, and the timber responds to both. Indoor humidity swings between about 35 per cent when the heating is on hard and 65 per cent in a wet autumn, and a floor has to cope with that range.
This is why we recommend a moisture meter reading before installation and why acclimatising the boards in the room matters. A wide solid board in a dry, constantly heated house will gap at the joints. An engineered board with a stable core takes the same conditions without moving noticeably.
