Best decking materials for Lancashire weather
Choosing the Best Decking Materials for the Lancashire Weather: A Homeowner’s Guide
If you live in Lancashire, you know that our weather is "characterful," to say the least. From the breezy heights of the West Pennine Moors to the salt-spray of the Fylde Coast and the persistent drizzle in the Ribble Valley, our outdoor spaces take a beating.
When considering a new decking installation, the most important decision you will make isn’t the colour or the furniture you’ll put on it—it’s the material. Choosing a product that can stand up to the damp, frost, and occasional heatwaves of Northern England is the difference between a deck that lasts twenty years and one that rots in five.
With over 15 years of experience in professional decking across the county, we’ve seen what works and what fails. In this guide, we’ll break down the best materials for the Lancashire climate to help you make an informed investment.
The Lancashire Climate Challenge: Why Material Choice Matters
Before we dive into the materials, we need to understand the enemy: moisture. Lancashire receives significantly more rainfall than the south of England. This constant dampness leads to three main problems for decks:
- Rot and Fungi: Timber that stays wet becomes a breeding ground for wood-rotting fungi.
- Slippery Surfaces: Algae thrives in damp, shaded spots, turning a beautiful deck into a skating rink.
- Expansion and Contraction: The cycle of freezing winters and humid summers causes materials to move. If the decking installation isn't done with the right gaps and fixings, the boards will warp or crack.
To get the most out of your outdoor space, you need a material that can handle a "Lancashire wash day" every other day.
1. Pressure-Treated Softwood: The Budget-Friendly Classic
Pressure-treated softwood (usually pine or spruce) is the most common choice for Lancashire decking. It is treated with preservatives (often referred to as 'Tanalised') to protect against rot and insect attack.
The Pros for Lancashire Homes
- Affordability: It is the most cost-effective way to transform your garden.
- Versatility: You can stain or paint it any colour to match your home.
- Availability: Being a staple of UK gardens, parts and replacements are easy to source.
The Challenges
In our wet climate, softwood requires the most maintenance. Without an annual application of high-quality deck sealer or oil, the wood will soak up water like a sponge. We recommend using "anti-slip" softwood boards, which feature grit-filled grooves, especially if your garden is north-facing or prone to moss.
2. Composite Decking: The Low-Maintenance Champion
In recent years, composite decking has become the gold standard for decking installation in the North West. Made from a blend of wood fibres and recycled plastics, it offers the look of wood without the organic vulnerabilities.
Why it excels in Lancashire
- Weatherproof: It doesn't rot, warp, or splinter, no matter how much it rains.
- Slip Resistance: Most modern composites are designed with high-friction surfaces, making them much safer in the wet than traditional timber.
- Colour Retention: Unlike wood, which turns silver-grey under UV light, composite stays the same colour for decades.
Expert Tip
If you opt for composite, ensure you choose a "capped" version. Capped composite has an extra protective layer that prevents moisture from penetrating the core, which is essential for our humid winters.
3. Hardwood Decking: The Premium Natural Choice
If you want a high-end look and are prepared to invest, hardwoods like Ipe, Balau, or Cumaru are incredibly dense and naturally oily. This makes them naturally resistant to water and decay without the need for heavy chemical treatments.
The Lancashire Benefit
Hardwood is incredibly durable. It feels solid underfoot and has a luxurious finish that is hard to replicate. Because the wood is so dense, it is much harder for algae to take root, meaning it stays cleaner and less slippery than softwood.
The Trade-off
It is significantly more expensive and requires professional decking specialists to install because it is so hard it often requires pre-drilling and specialist sawtooth blades. However, a well-maintained hardwood deck in a town like Preston or Whalley can last 30 to 50 years.
Practical Advice: Ensuring Your Deck Survives the Rain
Regardless of the material you choose, the quality of the decking installation is what determines its lifespan. Here are three professional tips we implement on every job:
1. Focus on the Sub-Frame
Many contractors cut corners by using cheap timber for the frame under the boards. We recommend using high-quality treated joists and, crucially, applying joist tape. This waterproof butyl tape protects the top of the timber joists from standing water that seeps through the gaps in the boards.
2. Proper Drainage and Airflow
A deck should never sit directly on the soil. We install our decks on raised pedestals or concrete footings to ensure air can circulate underneath. This airflow helps dry out the structure after a heavy downpour, preventing the build-up of stagnant moisture.
3. The 5-Degree Rule
We often build a very slight, almost invisible "fall" (incline) into our decks. This ensures that rainwater runs off the surface rather than pooling in the middle of your boards.
Cost Estimates and ROI: Is it Worth It?
Investing in a deck is one of the most effective ways to increase your property value in the UK. According to recent estate agent surveys, a high-quality deck can provide an ROI (Return on Investment) of between 70% and 100% of its cost.
Estimated Costs (Labour & Materials)
- Softwood Decking: £80 – £120 per square metre.
- Composite Decking: £150 – £250 per square metre.
- Hardwood Decking: £200 – £350+ per square metre.
Note: Prices vary based on site preparation, height of the deck, and choice of balustrades.
Beyond the financial return, a deck provides "lifestyle ROI." It creates a level, clean space for dining and relaxing that stays usable even when the Lancashire lawn is too soggy to walk on.
Why Choose a Professional Decking Contractor?
It can be tempting to treat a deck as a DIY weekend project. However, Lancashire’s clay-heavy soil and varying elevations often lead to structural issues if the foundations aren't handled correctly.
When you hire us for your decking installation, you aren't just paying for boards to be laid. You are paying for:
- Local Knowledge: We understand the soil types in areas like Chorley, Blackburn, and Burnley.
- Precision Engineering: We ensure every beam is load-bearing and every screw is corrosion-resistant.
- Warranty: We stand by our work, giving you peace of mind that your investment is protected against the elements.
We have spent years refining our techniques specifically for the North West climate, ensuring that every project we finish is built to endure the wettest winters and the brightest summers.
Conclusion: Ready to Transform Your Garden?
Choosing the right material for your Lancashire home doesn't have to be a headache. Whether you want the natural beauty of a hardwood terrace, the affordability of treated softwood, or the "fit and forget" convenience of modern composite, the key is quality installation.
