Pressure-Treated Sheds: Customisable with Free Installation

Image of  pressure-treated garden shed

Pressure-treated sheds let you take your outdoor storage buildings to the next level. These options are made from 100% natural timber and specially treated to make them last longer.

So, no matter what you want to do with your shed – whether storing bicycles, keeping garden tools, or creating space for a workshop – we can help.

Designed To Last – Built For People Who Love Quality

If you want your shed to last, then pressure-treating it is one of the best things you can do. The process allows wood preservatives to penetrate the timber deeper, preventing pesky organics from gaining a foothold. The result is a structure that looks better and lasts longer.

With a pressure-treated garden shed, your outbuilding can withstand anything the British weather throws at it.

Whether it is freezing temperatures in winter or endless rain in April, this construction method ensures it stands the test of time.

Redwood Timber – The Heart Of Our Craftsmanship

Redwood timber stands at the heart of our craftsmanship. We love this wood for its purity, quality, and ability to resist warping, water, and freeze-thaw weathering.

Redwood is robust and resilient, and its natural beauty looks fantastic in British gardens. Sheds look well-built and strong—like permanent fixtures in your garden.

Furthermore, when you come to us, we guarantee no OSB (oriented strand board) an artificial material. These by-products aren’t as durable and give sheds a cheap feel we want to avoid.

Built Around Your Endurance Requirements
Pressure-treated sheds from us are more than just storage spaces – they’re architectural in their own right. That’s why we build tanalised sheds with beauty and durability in mind.

For example, our sheds come with toughened glass windows to survive whatever your garden throws at them. Stray tennis balls, accidental pokes with rake handles and DIY accidents are usually no match for our high-strength glazings.

Furthermore, with its pressure treatment, the redwood construction offers extra protection. It ensures your garden equipment or hobby space remains pest- and water-free during storage, letting you make memories in your shed that last a lifetime without the need to replace the building every few years.

Customisation Options

Image of  tanalised treated garden shed

All pressure-treated sheds for sale from 1st Choice Leisure Buildings are 100% customisable with an optional colour finish and free assembly. With us, you can tailor options to your specific requirements (whatever they happen to be).

For example, do you fancy a colour that complements your garden’s theme? With us, it’s easy. We can paint your shed any shade!

We can also add practical and aesthetic features to the outbuilding to reflect your style and preferences, including optional insulation for those winter crafting projects!

Free Installation – What Could Be Easier?

Moreover, we offer free installation on all our wooden sheds. This means you won’t have to worry about additional costs or the hassle of setting it up yourself.

While you can take the DIY approach, why not get our team to do it for you? They can set up your new shed in hours, letting you enjoy it immediately (instead of waiting around).

Visit Our Showroom And See Our Quality For Yourself

Still not convinced? Why not visit our showroom to see our pressure-treated sheds for yourself? Here, you can walk inside, take a closer look at the quality of the material, and decide which features you want your bespoke installation to include.

We currently have a showroom location twixt Woking, Ripley and Guildford in Surrey. Here, our team can explain the craftsmanship that goes into each shed and what suits your garden.

Don’t be afraid to ask questions. We’re obsessed with all things shed-related!

Why Choose Us?

1st Choice Leisure Buildings goes above and beyond to ensure you get the highest quality shed. See our customer feedback. We offer bespoke solid wood construction, numerous customisation options, and reinforced glass to help prevent stray objects from smashing your windows (a common occurrence for sheds!)

Let us know what shed you’d like, and we will make it. We tailor designs to your precise requirements, giving you outbuildings that fit your lifestyle. No wonder we have such great feedback.

Explore Possibilities With Us
You can use our sheds for numerous purposes, such as gardening furniture storage, workshop activities, or hobby spaces. Please tell us what you want to use it for, and we will develop a matching design.

Ultimately, we want you to own a shed that ticks all your boxes. So what are you waiting for? Call today on 01483 237550, and let’s get started on your new, long-lasting timber shed.

Frequently Asked Questions About Pressure Treated Sheds

No results!
  • Are pressure-treated sheds suitable for Surrey’s wet weather?
    Yes. Pressure-treated timber is specially treated to resist rot, decay, and insects, making it perfect for Surrey’s damp winters. Placing your shed on a solid base and checking the roof and paint finish regularly will keep it in top condition for years.
  • Are these sheds secure enough for tools and bikes in Surrey homes?
    Yes. Our sheds use strong tongue-and-groove timber and quality locks. They are secure for storing tools, bikes, lawnmowers, and other garden equipment.
  • Can I see a display shed before buying in Surrey?
    Yes. You can visit our showrooms near Guildford, Woking, and Ripley to see the size, quality, and finish before buying. This helps ensure the shed fits your garden and storage needs.
  • Can pressure-treated sheds be painted or customised in Surrey?
    Yes. The timber has a natural green-tan finish, but you can paint or stain your shed. Personalise it to match your garden. We can add features such as windows, shelves, or additional doors if needed.
  • Do you deliver and fit sheds in Guildford, Woking, or the surrounding Surrey areas?
    Absolutely. We deliver and professionally install wooden sheds - free of charge - across Surrey, including Guildford, Woking, Cranleigh, and Farnham. Our team ensures each shed is level, secure, and built to last.
  • Do you offer insulated sheds in Guildford or Woking and Surrey?
    Yes. Insulated sheds are ideal for workshops, garden offices, or studios. They protect your tools and create a usable space all year round, even in Surrey’s colder months.
  • How long do pressure-treated sheds last in a Surrey garden?
    With proper care, pressure-treated sheds last 15–20 years. Keep the base dry. Clear leaves and debris from the roof. Treat the timber occasionally to prevent weathering - especially in Guildford and Woking, where rainfall is common.
  • How much maintenance do pressure-treated sheds need in Guildford and Woking?
    Very little maintenance is needed. Check the roof and base regularly. Treat the timber every few years. These steps keep your shed looking great and lasting decades.
  • What size pressure-treated shed is best for a garden in Guildford or Woking and Surrey?
    Consider what you need to store to choose the right shed size. A 6x4ft shed fits garden tools. Choose an 8x6ft or 10x8ft shed for bikes, lawnmowers, or a small workshop. Always measure your garden—especially if space is tight in Guildford or Woking.
  • What’s the best base for a pressure-treated shed in Surrey gardens?
    A solid, level base is essential. In Surrey gardens, concrete slabs, paving stones, or a timber frame base work best. This lifts your shed off damp soil to prevent rot and keep it level for years.
