What We Build

Decking is the core of what we do, and everything else grows out of it — the steps, the railings, the screening and the buildings that end up sitting on top.

Composite Decking

Low maintenance boards that will not rot, warp or need staining, typically £150–£250 per square metre fitted. See composite decking in Sheffield.

Timber Decking

Pressure treated softwood from around £100–£150 per square metre fitted, with oiling every couple of years. See timber decking in Sheffield.

Plastic & UPVC Decking

Fully plastic boards for narrow passages, poor drainage and anywhere absolute minimum upkeep matters most. See plastic decking in Sheffield.

Balustrades & Deck Lighting

Glass, metal and timber railings, plus recessed in‑deck lights so the space works after dark. See balustrades and deck lighting.

Garden Rooms & Offices

Insulated, double glazed and wired for power — usually built onto a deck. See garden rooms in Sheffield.

Fencing

Closeboard, panels, hit and miss and slatted screens, plus composite fencing. See fencing in Sheffield.

Where the Deck Goes Matters as Much as What It Is Made Of

Most people come to us knowing roughly where they want the deck — usually straight out of the patio doors, because that is the obvious spot. Sometimes it is the right one. Often it is not, and it costs nothing to think about it properly before anything is built.

Sun is the one that catches people out. A deck immediately outside a north‑facing kitchen may be in shade exactly when you would want to sit on it, while a corner further down the garden catches the evening light. Wind matters too, particularly on Sheffield's higher and more exposed streets, where a beautiful open deck can be unusable without some screening behind it.

Then there is the practical side. How far is it from the kitchen if you are carrying food out? Who overlooks it, and would a slatted screen or a taller boundary fix that? Is there a mature tree in the way — and rather than removing it, could the deck be cut around it? We have done exactly that, and it usually makes the finished space better rather than worse.

We will walk the garden with you and give an honest opinion, including when we think the obvious position is the wrong one. For more ideas, have a look at our decking ideas gallery or the benefits of decking.

You May Not Need a Whole New Deck

A tired‑looking deck is not the same as a failed one, and the difference is worth several thousand pounds.

Before quoting on any replacement we lift a board or two and look at the frame underneath. If the joists and posts are sound, you may only need new surface boards — a considerably cheaper job, and one we do regularly across Sheffield. Where the subframe has softened through water ingress or ground contact, full replacement is the safer route, because there is no sense fitting new boards onto a frame that will give way in a couple of years.

There is a useful middle option people rarely know about. If your existing timber frame is still solid but the boards are past their best, switching to composite boards on that frame gets you a low‑maintenance surface without paying for a complete rebuild. Worth asking about before you accept a quote for the whole thing.

The signs worth a closer look: boards visibly warped, cracked or pulling away from their fixings, balustrades that move when you lean on them, or gaps opening up between boards.

How We Work

Supply and fit. We source the boards, fixings and frame so the whole job is our responsibility. Fit‑only is possible — ask us, and we will be straight about the trade‑offs.

Provisional quote within 24 hours. Send photos and rough measurements and we can usually price it without visiting first.

Our own team. Family run, no subcontractors, and the people who quote the job are the people who build it.

Fully insured. Public and Employer's Liability cover in place.

Two to three days for most decks. Longer for split‑level, raised or heavily sloping sites, and we will say so up front rather than overrun.

Tidy site, tidy finish. Cleared down at the end, with waste taken away.

Send Us Your Measurements

A couple of photos and a rough size is enough for a provisional figure, usually back with you within 24 hours and without needing a visit first.

Frequently Asked Decking Questions
How much does decking cost in Sheffield, and what affects the price?

Costs vary with size, material and ground conditions. As a rough guide, timber decking starts from around £100–£150 per square metre supplied and fitted for standard softwood, while composite typically runs from £150–£250 per square metre depending on board profile and subframe requirements.

Those figures shift with the site. Many Sheffield gardens, particularly around the older terraces in Heeley, Hillsborough and Sharrow, have sloped or uneven ground that needs more subframe work to get a flat, stable surface, and that groundwork adds time and materials. Access matters too — some city centre back yards are genuinely awkward to get materials into. Send photos and measurements and we can usually give a provisional figure within 24 hours without visiting first.

Do I need planning permission for decking in Sheffield?

In most cases no. Garden decking generally falls under permitted development, meaning no application to Sheffield City Council, as long as the platform sits no more than 300mm above existing ground level and does not cover more than half the land around the original house.

It gets more complicated on a raised plot, which is common on Sheffield's hillside streets, or if you are in a conservation area or a listed property. Separately, where there is a drop of more than 600mm from the deck edge, guarding is required under Part K of the Building Regulations — which is why a raised deck quote should always include balustrades. We build decks rather than assess planning applications, so treat this as the general position and check with the council if your garden is elevated or your property is listed. We would far rather flag it early than have you find out afterwards.

How long can I expect timber decking to last?

More depends on maintenance than on the wood itself. A well maintained softwood deck, treated with a quality decking oil or stain every two to three years, will typically give around 15 years before full replacement. Hardwoods such as Balau or Ipe last considerably longer, but cost significantly more and are less commonly installed around Sheffield.

What shortens that lifespan here is the local climate. We get a fair amount of rain, and ground level moisture is an issue in gardens that drain poorly or sit in shade. North facing gardens in areas like Walkley and Crookes see moss and algae build up faster than people expect, which accelerates surface degradation if left. A good scrub once a year and a fresh coat of treatment when needed makes a noticeable difference.

Does composite decking hold up well in Sheffield's weather?

It is one of the main reasons demand has grown steadily. Sheffield weather is genuinely variable — wet winters, occasional frost, and summers that swing between dry spells and heavy rain in the same week. Good quality composite boards do not absorb water the way timber does, so they are far less prone to the swelling, splitting and rot that shortens a timber deck's life, and better products have textured anti‑slip surfaces that keep grip when wet.

What composite does less well is prolonged strong sun. Some boards fade slightly over time in very exposed south facing positions, though most reputable brands now treat for UV as standard. If your deck is going in a particularly sunny spot, it is worth discussing board choice, as some profiles hold colour better over ten to fifteen years.

When should I replace my decking, and is it always a full replacement?

Not always, which surprises a lot of people. The visible signs are the starting point — boards warped, cracked or pulling away from fixings, balustrades that move when leaned on, or gaps opening between boards. What most people overlook is the structure underneath, so before any project we lift a board or two and check the joists and posts.

If the frame is solid you may only need new surface boards, which is a significantly cheaper job. Where the subframe has softened through water ingress or ground contact, full replacement is safer. And if your timber frame is still sound but the boards look tired, switching to composite boards on the existing frame is a cost effective way to move to a low maintenance surface without a complete rebuild.

Is composite decking installation much different to timber?

It can be, depending on the system. If we are replacing boards on a sound existing timber frame, the installation is very similar to timber. Where a full matching composite subframe is used, that is often aluminium and goes together differently.

The other difference is fixings. Many composite systems use hidden clips rather than screws, which leaves no screw heads showing across the surface and builds in the expansion gaps the boards need as temperatures change. It is a noticeably different process, and getting the joist spacing right to the board manufacturer's specification matters more than it does with timber.

What is the difference between composite and UPVC decking?

They get confused because both are sold as low maintenance alternatives to timber, but they look and perform differently. Composite is a blend of wood fibre and recycled plastic, with a more natural, wood‑like appearance and a more substantial feel underfoot. UPVC is entirely plastic‑based, which makes it genuinely maintenance free but can look less natural and feel slightly hollow.

For most Sheffield homeowners composite is the more popular choice where appearance matters alongside low upkeep. UPVC works well in specific situations — narrow side passages, areas with poor drainage, or projects where absolute minimum maintenance outweighs everything else. Neither is universally better. We install both and will tell you which we would lean towards for your garden.

Do you supply and fit, or can I buy my own decking boards?

We offer both, with an honest caveat about the fit‑only route. Jobs run smoothest as supply and fit, where we take responsibility for sourcing the right materials, quantities and fixings from the start. If there is a shortage, or a specific board profile gets discontinued mid‑project, which does happen with some composite ranges, we deal with it rather than you.

If you have already bought boards and want fitting only, we are happy to quote. Just be aware that shortages or compatibility issues with fixings and clips can affect both the timeline and occasionally the finish. We will always flag that up front rather than discover it halfway through.

How long does a decking installation take?

For a straightforward deck in the 20–40 square metre range, which covers most back garden projects around Sheffield, expect two to three days on site. That covers groundwork, the subframe, and fitting boards along with finishing details like balustrades and fascia.

More complex jobs — split level decking, raised structures with steps, or anything involving significant groundwork on a slope — run to four or five days. Sheffield gardens are rarely straightforward for levels and access, and we would rather build in enough time to do the groundwork properly than rush it. We give a clear timeline when we quote and we will not underquote the time to win the work.
