Decking is one of those garden projects where the gap between a good job and a poor one isn’t obvious when you first stand on it. The boards look level. The finish is clean. It feels solid enough. But give it twelve months of Surrey weather – wet winters, damp ground, leaf fall sitting on the surface – and the difference in how it was built starts to show.
Boards that cup, split or go green within a year. A subframe that’s started to flex because the joists were undersized or the posts weren’t set deep enough. Steps that feel solid in summer but develop a rattle by spring. These aren’t material problems – a decent timber or composite board will last fifteen or twenty years in the right hands. They’re construction problems that start below the deck surface, in the subframe and post foundations that nobody photographs.
Dorking gardens add their own specific challenges. Many properties in and around the town have sloping plots – particularly those backing onto the Surrey Hills – which means raised decking on a substantial subframe rather than a simple ground-level board lay. Mature trees nearby mean roots to work around and leaf debris to account for in board spacing. Shaded aspects that stay damp longer than open plots.
As builders in Dorking who have worked on outdoor projects across the area for over 17 years, we know what lasts here and what doesn’t – and we build accordingly.
Dorking’s Decking Installers – Built From the Ground Up
DFB Building and Landscaping has been building decking across Dorking, Westcott, Brockham, Capel and the surrounding villages since 2007. We treat decking as a structural build, not a cosmetic one – because a deck that flexes, bounces or rots from underneath is a safety issue as much as an aesthetic one.
We work with pressure-treated softwood, hardwood and composite decking. We’ll give you an honest comparison of what each one costs, what it looks like over time in a Surrey garden, and which one genuinely suits your plot, aspect and budget – not just what we have in the van.
Decking Options We Install in Dorking
The board material is the decision most people start with. Here’s what each option actually means for a Dorking garden over the long term.
Pressure-Treated Softwood
The most widely used decking material and, when specified and installed correctly, genuinely good value for money. Pressure treatment protects against rot and insect damage. Board quality varies significantly – we specify C24 structural grade boards on a correctly sized subframe, not the lighter sections that look the same in a photo but feel different underfoot.
Best for: Most garden decking projects where budget is a consideration and the finish will be maintained with occasional oiling or staining.
Hardwood Decking
Visually richer and significantly denser than softwood – hardwood decking has a quality of finish that reads differently in a garden. Naturally resistant to rot and far less prone to splitting or cupping. Higher material cost but lower maintenance over time. We source sustainably certified hardwood and advise on species that genuinely suit a shaded or damp Surrey aspect.
Best for: Gardens where the visual quality of the material matters, higher-end builds, and plots with shaded or damp aspects where hardwood’s natural durability is genuinely valuable.
Composite Decking
Wood fibre and polymer boards that look like timber but don’t require the same maintenance regime. No annual oiling, no splintering, resistant to fading and staining. The range in composite board quality is wider than most people realise – from boards that look plastic after a year to genuinely impressive products that hold their appearance well. We install composite on a correctly engineered subframe – which is where most composite deck failures actually start.
Best for: Homeowners who want a low-maintenance finish, families with young children who use the deck heavily, and properties where regular maintenance isn’t practical.
Raised & Multi-Level Decking
Many Dorking plots slope significantly – particularly those on the greensand hills above the town. A raised deck on a substantial post and beam subframe is often the best way to create usable outdoor space on a sloping garden without the cost of full terracing. Height changes the structural requirements considerably. We size posts, beams and joists correctly for the span and load, and set posts in concrete at the right depth.
Best for: Sloping Dorking gardens where a ground-level deck isn’t practical, and properties wanting to create distinct outdoor zones at different levels.
Decking with Steps & Balustrades
Steps onto a deck need to be correctly proportioned and securely fixed – not an afterthought bolted on at the end. Balustrades on raised decking aren’t optional when the drop is significant – they’re a safety requirement. We build steps and balustrades as part of the overall deck design, not add-ons that look slightly different from the rest.
Best for: Raised decks, decks connecting to existing garden levels, and any project where the overall look needs to read as a single coherent structure.
Decking Repairs & Subframe Replacement
Sometimes the boards are fine but the subframe underneath has failed. Sometimes it’s the other way around. We assess honestly – if the subframe can be repaired and new boards laid on top, we’ll say so. If the whole thing needs to come out and start again, we’ll tell you that too and explain why.
Best for: Existing decks that are bouncy, uneven or showing rot, where a full replacement may not yet be necessary.
Building Decking That Lasts in a Dorking Garden
Surrey gardens are not the same as gardens in a dry, flat part of the country. The combination of significant rainfall, clay-heavy ground in many parts of Dorking, mature trees, and shaded aspects creates specific challenges for decking that need to be thought about at the design stage – not discovered after the first winter.
Ventilation under the deck
Decking laid tight to damp ground rots from below regardless of how good the boards are. We maintain adequate clearance between the deck and the ground surface and ensure air can circulate freely under the structure.
Board spacing for drainage
Gaps between boards aren’t just aesthetic – they’re how surface water gets away. We install boards at the correct spacing for the material and ensure there are no low points where water can pond on the surface.
Post foundations on clay ground
Posts set directly into clay ground without proper concrete footings move seasonally. We set every post in concrete at a depth that gets below the zone of seasonal movement in Dorking’s clay soil.
Timber species and treatment for shade
A shaded aspect in a Surrey garden stays damp for longer after rain and grows algae faster. We advise on the right board species and treatment for the specific aspect – not a one-size solution that suits a sunny south-facing plot.
How Your Decking Project Works
From choosing the right material to the day you walk out onto a finished deck – here’s how we run decking projects in Dorking.
Free Site Visit
We come to your garden, look at the slope, the aspect, any trees or drainage considerations, and talk through what you want from the space. We’ll suggest the material and structure that genuinely suits your plot.
Written Quote
Clear and itemised – subframe, posts, boards, fixings, steps and balustrades if needed. You know exactly what’s included before any work starts.
Ground Preparation
Post positions are marked out, footings dug and concreted. Any ground clearance or levelling needed beneath the deck area is done before the frame goes up.
Subframe Build
Posts, beams and joists go up to the correct specification for the span and deck height. This is the structural phase – we don’t move on until the frame is level, square and solid.
Boards, Steps & Finishing
Boards are laid at the correct spacing, steps and balustrades fitted and everything checked for level and stability. We clean up and leave you with a deck that’s ready to use.
