Service overview
What building a deck actually involves
A deck is only as good as what's underneath the boards. The substructure (posts, bearers and joists) carries every bit of load the finished surface will ever take, and it has to be set out to the right spans and centres before a single board goes down. Lawton Landscapes builds the substructure and lays the deck as one job, so the two are designed to work together rather than the frame being someone else's guesswork.
Work starts with setting out post positions and footings, checking the fall of the ground and how the deck will be supported, whether that's on concrete pad footings, post supports set in the ground, or ledger-fixed to the house where appropriate. Joists are then set at centres suited to the board being used and the direction they'll span, with noggins added where boards run at an angle or over long unsupported lengths.
Ventilation underneath is not optional. A deck built low to the ground or over damp clay without airflow beneath it will trap moisture against the frame, and timber rots from underneath long before it looks bad on top. Getting the void, the fall of the ground beneath and the edge detailing right at the start is what keeps a deck sound for years rather than needing boards replaced within two or three seasons.
Substructures are set on solid, level supports with proper spans and ventilation beneath, so boards don't bounce, cup or rot early. Timber and composite boards are both available depending on how much maintenance you want to take on.
Decking often works best where a garden slopes away from the house, turning an awkward level change into the most used part of the garden.
Who this is for
- Homeowners wanting a raised, level seating or dining area on a garden that slopes away from the house
- Anyone extending living space out from bi-fold or French doors onto a hard, flat outdoor floor
- Families replacing an old deck that has gone soft, spongy or slippery underfoot
- Homeowners choosing composite boards for a lower-maintenance alternative to timber
- Gardens needing steps and a balustrade to manage a level change safely
Every project includes
- Properly spanned, ventilated substructure
- Timber or low-maintenance composite boards
- Level, solid finish with neat fascias and edges
- Steps and balustrade where levels require them
- Free site visit, bespoke written quotation and a 2-year workmanship guarantee.
The cost of getting it wrong
What happens when a deck is built without a proper substructure
A weak deck rarely announces itself straight away. It starts as a slight bounce underfoot on one section, a board that's begun to cup or split, or green algae building up in a shaded corner. Underneath, joists set too far apart are flexing under load, or a support post has moved because its footing was never taken down to firm, undisturbed ground.
The real damage happens where ventilation was skipped. Boards laid tight to the ground, or a frame boxed in without any airflow, sit in permanently damp air. Timber joists in that environment rot from the inside, often well before there's a visible sign on the surface, by the time a board fails underfoot, the frame beneath it can already be compromised.
There's also a safety dimension that gets overlooked at the design stage: steps without a proper rise-and-going relationship, and a balustrade that isn't fixed into solid framing, are both genuine hazards on a deck that's more than a step or two off the ground. Slip resistance matters too; boards that look good dry can be treacherous wet, particularly on a north-facing deck that never fully dries out.
A deck rebuilt on a proper substructure, from level supports upward, costs less over its life than patching a failing frame every couple of years. Where an existing substructure is genuinely sound, that will be said plainly; where it isn't, the reasons will be explained at the site visit before any commitment is made.
Common mistakes we're called in to fix
- Setting joists too far apart for the board being used, so the deck bounces and boards eventually crack
- No ventilation gap beneath the frame, trapping moisture against timber joists
- Footings that aren't taken down to firm, undisturbed ground, so posts settle unevenly
- Fixing a balustrade to the decking boards or fascia instead of into structural framing
- Ignoring slip resistance on boards used in shaded or north-facing gardens
- Building level decking straight onto a sloping garden without accounting for fall and drainage beneath
Our process
How your decking project runs, step by step
-
Step 1
Free site visit and measure
Dominic visits the garden, checks ground levels, slope, existing structures and how the deck will connect to the house, and talks through how you plan to use the space and which board type suits it.
-
Step 2
Bespoke written quotation
You receive a written quotation covering footings, substructure, boards, fascias, steps and balustrade if needed, priced for your garden specifically. No 'from' pricing, and no charge for the visit or the quote.
-
Step 3
Footings and substructure
Footings are set down to firm ground, posts and bearers are fixed level, and joists are installed at centres suited to the board and span, with ventilation built into the void beneath.
-
Step 4
Boarding and fascias
Boards are laid with consistent, correctly sized gaps for drainage and movement, cut cleanly around obstructions, and finished with fascia boards to hide the frame edge and give a clean line.
-
Step 5
Steps and balustrade
Where the deck sits above ground level, steps are built to a safe, consistent rise and going, and a balustrade is fixed into structural framing rather than the boards or fascia alone.
-
Step 6
Handover and 2-year guarantee
The site is cleared and you're walked round the finished deck, including honest maintenance advice for the board type you've chosen. Workmanship is covered by a 2-year guarantee, and Dominic remains the person you contact.
What you get
The difference a properly built job makes
A frame built to carry the load
Joist centres and spans are set for the board being used, so the finished deck doesn't bounce, flex or develop soft spots under furniture and foot traffic.
Ventilation that protects the timber
A proper void and airflow beneath the frame stops moisture sitting against joists, which is what causes rot from underneath long before it's visible on the surface.
Solid, level supports from day one
Footings taken to firm, undisturbed ground mean posts don't settle unevenly, so the deck stays flat rather than developing a lean over its first winter.
The right board for how you'll use it
Timber and composite are discussed honestly against your budget, maintenance appetite and how shaded the space is, rather than one material being pushed regardless of the garden.
Safe steps and a properly fixed balustrade
Where a deck involves a level change, steps and balustrade are built into the structural frame, not bolted onto boards or fascia as an afterthought.
Fully insured, properly guaranteed
£1m public liability insurance and a 2-year workmanship guarantee, so you're covered while the work happens and afterwards.
In detail
Decking in Colchester: materials, methods and variations
Substructure: spans, joist centres and ventilation
The substructure is set out before anything else is decided. Joist centres and permitted spans depend on the board thickness and material, composite boards typically need tighter joist centres than solid timber decking of similar thickness, and getting this wrong is the single most common cause of a bouncy or short-lived deck.
Ventilation beneath the frame is built in as standard: a clear air gap between the ground and the underside of the joists, kept clear of vegetation and debris, so moisture doesn't sit trapped against the timber. On decks built low to the ground, or over heavy clay that holds water, this void needs particular attention, sometimes with a membrane or gravel bed beneath to manage ground moisture.
Timber vs composite boards
Timber decking, usually softwood, sometimes hardwood, has a warmer, more traditional look and can be sanded and re-oiled over its life, but it needs regular cleaning, oiling or staining to stay looking right and to resist splintering and greying.
Composite boards cost more upfront but need far less upkeep: no annual oiling, better resistance to splitting and rot, and consistent colour over time. The trade-off is a different feel underfoot and a look some homeowners prefer less than natural timber. Which suits a given garden depends on budget, how much maintenance you want to take on, and how shaded the deck will be, all discussed properly at the site visit rather than decided for you.
Slip resistance and sloping gardens
A board that grips well when dry can be genuinely slippery once wet, particularly in shaded, north-facing corners of a garden that never fully dries between rain showers. Grooved or textured boards, and composite ranges with a textured cap, are chosen for those areas rather than a smooth board that looks good but performs poorly underfoot.
On a sloping garden, decking is often the practical answer where a patio would need extensive retaining work. The substructure is built up on posts of varying height to create a level platform, with the ground beneath still allowed to fall naturally and drain, rather than being built up or trapped by the frame.
Steps and balustrade
Any deck that sits more than a step above the surrounding ground needs steps built to a safe, consistent rise and going, and in most cases a balustrade for the raised edge. Both are tied into the structural frame (posts and noggins) rather than fixed through the decking boards or fascia alone, which is a common shortcut that leaves a balustrade able to work loose under load.
Fascia boards are fitted to close off the visible edge of the frame, giving a clean finished line and hiding the joist ends, and are detailed to still allow the ventilation gap beneath to do its job.
Aftercare: keeping a deck sound
Timber decking benefits from an annual clean and re-oil or re-stain, ideally before winter, and from keeping the ventilation gap beneath clear of leaves, soil and plant growth that can block airflow. Composite boards need far less; a wash down to remove algae and debris is generally enough.
On both materials, gaps between boards should be kept clear rather than allowed to fill with debris, since that's what holds moisture against the board edges. Straightforward aftercare advice specific to the board you've chosen is given at handover.

Questions
Decking questions we're asked most
How much does a new deck cost in Colchester?
Every deck is measured and priced individually, because cost is driven by the size and height of the deck, ground conditions, the substructure needed, and whether timber or composite boards are used, not by a headline square-metre rate. No 'from' prices are advertised. Book a free site visit and you'll get a bespoke written quotation with the work set out clearly.
How long does it take to build a deck?
A straightforward domestic deck typically runs across several working days, with raised decks, steps, balustrades or larger areas extending that. A realistic timescale is given with the written quotation, and you'll be told in advance which days work will be taking place.
Do I need planning permission for a deck?
Most domestic decks fall under permitted development, but height above ground, proximity to boundaries and the proportion of garden covered can all affect this, and requirements differ for listed buildings and conservation areas. This is checked and explained at the site visit for every job.
Timber or composite, which is better?
Neither is universally better; it depends on budget, how much annual maintenance you want to take on, and how shaded the garden is. Timber costs less upfront and needs regular oiling; composite costs more but needs far less upkeep and resists rot better. This is discussed honestly against your garden at the site visit.
Will a deck rot if it's built low to the ground?
Not if it's built properly. A deck close to the ground needs particular attention to the ventilation void beneath the frame, sometimes with a membrane or gravel bed to manage ground moisture, so air can still move beneath the joists and prevent rot.
What guarantee comes with the work?
All workmanship is covered by a 2-year guarantee, and Lawton Landscapes carries £1m public liability insurance. Dominic runs the job and remains your point of contact, so if anything needs looking at afterwards you contact him directly.
Can decking be built on a sloping garden?
Yes, decking is often the most practical way to create a level, usable area on a sloping plot, since posts of varying height can build up a flat platform without the retaining work a patio would need on the same slope.
Do I need a balustrade on my deck?
Where a deck sits raised above the surrounding ground, a balustrade fixed into the structural frame is the safe approach, and is factored into the design and quotation from the outset rather than added as an afterthought.
Do you build decking outside Colchester?
Yes. Decking is built throughout Essex and into Suffolk, including Chelmsford, Braintree, Maldon, Witham, Tiptree, Halstead, Clacton-on-Sea, Harwich and Sudbury.
Can decking be combined with other garden work?
Frequently it is. Decking is regularly built alongside steps, raised sleeper beds, planting and fencing so that levels and materials work together, and the whole garden is finished as one project by one landscaper.
Often done alongside
Sleeper Steps
Safe, even steps that make a sloping garden genuinely usable end to end.
Sleeper & Raised Beds
Sleeper edging and raised beds that give a garden structure and defined planting.
Fencing
Straight, solid, well-set fencing, with panels assembled and fitted on site where needed.
Planting
Planting schemes chosen to suit your soil, aspect and how much time you want to give it.
