Decking is one of those jobs where the difference between a good job and a bad one is invisible until two winters in. Cheap decking sags, splits along the boards, and starts to rot at the joist contact points within a few years. Done properly, with a treated timber frame at the right joist spacing and the right fixings, it stays level and usable for a decade plus.

Whats included

What you get with every job

  • Site clearance and ground preparation
  • Concrete pad foundations or post supports as required
  • Pressure treated softwood frame at correct joist spacing
  • Boards in your chosen material (softwood, hardwood, or composite)
  • Stainless steel or coated decking screws (no nails)
  • Edging, steps and balustrade where needed
  • Skirting around the frame so the underside is hidden
Options

Materials and approaches we work with

Composite

The low maintenance option. Won't fade much, won't rot, no annual oiling. Costs more than timber upfront but less over time. Trex and Millboard are the main brands we use.

Hardwood (Iroko, Balau)

Premium. Looks beautiful, ages to a silver-grey if untreated, lasts twenty years plus. Heavier on labour and material cost.

Softwood (treated pine)

Budget friendly. Needs an oil or stain every two to three years to stay looking good. Lifespan ten to fifteen years if maintained.

Process

How the job runs

  1. 01

    Site visit

    We check ground levels, soil type, and whether the area drains. Decking on boggy ground needs extra prep.

  2. 02

    Frame

    Pressure treated C24 timber, joists at 400mm centres for softwood and 350mm for hardwood. Joist hangers and noggins where they need to be.

  3. 03

    Boards

    Boards laid with a 5mm to 8mm gap depending on material, screwed (never nailed) into every joist. Cuts sealed where they need to be.

  4. 04

    Finish

    Skirting fitted around the frame so you can't see the joists, and any steps or balustrade trimmed in. If softwood, a first coat of oil at the end.

Cost

What affects the price

Quotes are itemised, but here's what moves the number up or down.

  • Board material (composite roughly twice the price of softwood)
  • Deck size and complexity (raised decks with balustrade cost significantly more than ground-level decks)
  • Ground conditions (soft or sloping ground needs more frame work)
  • Steps, balustrade, and built-in seating
  • Whether the existing surface needs removing

For honest indicative ranges, see the pricing guide.

Timeline

How long it takes

A 15 to 20 square metre ground-level deck takes three to five working days. Raised decks with balustrade and steps run a week to ten days.

Aftercare

Looking after the finished job

Composite needs nothing more than a brush and a wash. Hardwood, leave it alone if you like the silvered look or oil annually if you want to keep the colour. Softwood needs cleaning and re-oiling every two to three years to stay looking good.

Highly recommended! Alfie and his friend changed our fences and did a fantastic job. They were efficient, quick, hardworking and the price was very reasonable. Really pleased with the result. Thank you again.

Alfie and his team did a great job replacing our back fence. It was mess due to neighbours trees and rubbish pushing up against the wood panels. They cleared everything up and ensured nothing putting pressure against the new fence. They worked fast, removed all rubbish, and well priced. The fence looks fantastic. We will be using his services again, highly recommend.

FAQ

Decking FAQs

Composite or timber?

Composite if you don't want to think about maintenance for fifteen years. Timber if you're happy to oil it once a year or like the way real wood weathers. Both look great when fitted properly.

How long does decking last?

Composite twenty years plus, hardwood twenty, treated softwood ten to fifteen if you maintain it. The frame underneath outlasts the boards if it's pressure treated and ventilated.

Will it get slippery in winter?

All decking gets slippery when wet, especially under shade. Composite tends to be marginally better than timber. Grooved boards help slightly. The real fix is a yearly clean to stop algae building up.

Do I need planning permission for decking?

If the deck is more than 300mm above ground level, or it covers more than half your garden, you might need permission. Most ground-level decks fall under permitted development. We'll flag anything borderline.

Can you put decking next to the house?

Yes, but the deck surface needs to sit at least 150mm below the damp proof course, with a gap behind it for ventilation. Otherwise you get damp issues against the wall.

Can you lay decking over an existing patio?

Sometimes yes, if the patio is structurally sound. The frame sits on rubber pads on the existing surface. It saves on demolition costs and protects the patio underneath.
