Timber Joinery & Sheet Materials
Joinery Timber
Timber joinery is timber that we machine, grade and finish for construction and woodworking – planed, profiled or strength-graded so it is ready to use in framing, fit-out and finishing work. At Timberstore we stock an extensive range and selection of joinery timber, sheet materials and related timber products across seven categories, in both softwood and hardwood, for trade and retail customers who need the right material for building, finishing or workshop projects, with reliable delivery across the South East of England or collection from store.
With a deep selection of joinery products in stock, you can explore the full range online, shop by category and order the exact timber and sheet materials your project needs, with delivery through our extensive network across the South East. Our range covers timber products from structural timber that disappears inside a build to the mouldings, cladding, flooring and sheet materials that shape the finished result, helping builders, contractors, woodworkers and DIYers choose the right type, size and cut for the job, whether the work is a quick repair, a fit-out or a full home renovation.

PAR (Planed All Round)
Timber we plane smooth on all four faces for a clean, finished surface. It suits any job where the timber will be seen - shelving, framing, trim and general joinery. PAR joinery timber is ideal for shelving, cabinetry and internal doors, and its smooth faces help you create a flawless finish on any joinery project.
Sawn & Carcassing Timber
Structural softwood for the work behind the scenes - floor and roof joists, studwork and framing. We grade it C16 or C24 for strength, and stock it pressure-treated for damp or outdoor conditions. It is the ideal choice for the structural work behind a build, and we stock it in a wide range for joists, studwork and rafters on any project.
Cladding
Exterior timber cladding boards are available in a range of profiles including featheredge and shiplap, suitable for walls, outbuildings, garden offices, and agricultural buildings. Our cladding is pressure treated to help protect against moisture and reduce the risk of rot, making it well suited for exterior use in all weather conditions. For the best long term results we'd recommend finishing with a suitable exterior paint, oil, or preservative coating and always pay particular attention to any cut ends, as these should be treated before fixing.
Flooring
Softwood tongue and groove flooring boards are ideal for use as a structural subfloor beneath carpet, vinyl, or other floor coverings, and quality boards can also be sanded and finished as a visible floor in their own right - particularly popular on staircases, landings, and in older or character properties. We also stock chipboard T&G P5 flooring panels and OSB3 tongue and groove boards, both widely used as structural subfloor panels on suspended timber floors.
Skirting & Architrave
Finishing mouldings that frame a room - skirting along the floor and architrave around doors and windows - for a neat, professional finish indoors. These mouldings are designed to create a flawless finish around doors, door linings and window openings, and help you achieve a professional, modern style in any room.
Sheet Materials
Manufactured boards including plywood, MDF, OSB and chipboard, for flooring, walls, furniture and general construction. Browse our full Sheet Materials range. Explore our full selection of sheet materials online, and shop the range to find the perfect board for your project.
Firewood
Seasoned logs and kindling for wood burners, stoves and open fires.
Choosing the Right Quality Timber Products
The right choice comes down to two things: the wood, and where it is going, with joinery essential across furniture, cabinetry and timber frame building work. Whether the work is carpentry, cabinetry or fine joinery, the right timber is what turns good craftsmanship into a finished result that lasts and performs.
Softwoods such as redwood and whitewood are the everyday choice for construction and joinery, and are often the simplest option for DIY enthusiasts; hardwoods such as oak are denser and better suited to jobs where strength or appearance matters; engineered boards such as plywood, MDF and OSB are made for sheet applications like flooring and walls.
Our joinery timber is graded, in stock and ready to use, and if responsible sourcing is important, ask our team about FSC-certified products for anything from home improvements to larger commercial projects. Different joints serve different functions depending on load, stress and aesthetics. Location decides the rest, because timber joinery techniques also need to accommodate wood movement caused by moisture and temperature changes.
For anywhere exposed to damp or weather, choose pressure-treated timber; for dry interior work, untreated or appropriately graded timber is the sensible option. If you are not sure what suits your project, our team can offer expert advice to help you choose materials and joint-ready timber for your specific requirements and meet your budget and build needs. Whatever the scale of the job, our team can also offer expert advice to match the right product to your project, and help you create the finish you are after.
Understanding Timber Sizes (Nominal vs Finished)
We usually describe timber by its nominal size - the sawn size before it is planed - so a board known in the trade as "6 by 2" starts life at 47x150mm. Planing then removes a few millimetres from each face, leaving a finished size of roughly 45x145mm.
The same applies across our range: a 2x2 PAR, for example, is 50x50mm nominal and around 45x45mm finished. All finished sizes are approximate, so when clearances matter, always work to the finished dimension rather than the trade name.
Cut-to-Size Timber - Our Own Mill
We have our own mill and can cut timber precisely to size - not just sheet materials, but any joinery timber we stock. Our sheet materials come as full 8x4 sheets (2440x1220mm), with smaller tongue-and-groove OSB also available.
You will need to buy the full sheet, but once you have, we can cut it down for you on the machine to the exact sizes you need. Because each length is prepared to your exact specifications, you get boards finished to real precision that drop straight into the build with no waste.
The service scales from a single length to a full order to match the needs of any project. Cutting starts at a £5 minimum charge, which covers around five cuts. For anything more involved, message or call us for a bespoke quote. To add cutting to an online order, use code MILL02 at checkout.

Timber Joinery FAQs for DIY Enthusiasts
What is timber joinery?
Timber joinery is timber machined and graded for woodworking and finishing work. We select it to plane and profile cleanly, which makes it suited to trim, mouldings, door linings and any job where the finish shows. Our joinery products are stocked ready to plane and profile.
What are the three main types of timber?
The three main types are softwood, hardwood and engineered timber. Softwoods such as redwood and whitewood are the everyday choice for construction and joinery; hardwoods such as oak are denser and used where strength or appearance matters; engineered boards such as plywood, MDF and OSB are manufactured panels for sheet applications.
What is the difference between timber joists and timber joinery?
They sound similar but mean different things. Timber joists are structural members that support floors, ceilings and roofs; timber joinery is timber machined and graded for woodworking and finishing, such as mouldings, trim and door linings. In short, joists hold the building up, joinery finishes it off.
What is the weakest joint in timber?
The butt joint is generally the weakest. It places one piece of timber against another with a small contact area and relies on nails, screws or glue rather than any interlocking, so it has little strength of its own.
What is the difference between PAR and sawn timber?
PAR timber is planed smooth on all four faces for a finished appearance, while sawn timber is left rough from the saw. We use PAR where the timber will be seen; sawn or carcassing timber is used structurally where it will be hidden.
Softwood or hardwood - which should I choose?
It depends on the job. Softwood is cost-effective and easy to work, and covers most construction and general joinery; hardwood is denser and more hard-wearing, better suited to finishing joinery and pieces where appearance and durability matter. For most DIY projects the perfect starting point is softwood, while hardwood is the ideal pick where a piece has to last.
What sheet materials do you stock?
We stock plywood, MDF, OSB and chipboard. Each suits different jobs - OSB and plywood for structural flooring and sheathing, MDF for smooth painted finishes and furniture. Explore our range and full selection of sheet materials in the shop to find the perfect board for kitchens, wardrobes and other living spaces.
Do you offer a timber cutting service?
Yes - we have our own mill and can cut any timber we stock precisely to size. Cutting starts at a £5 minimum charge; for bespoke work, message or call us for a quote, or add code MILL02 to your online order.
Is joinery a good career in the UK?
Yes - there is steady demand for skilled joiners and carpenters, good earning potential, and a clear route in through apprenticeships.
