GARDEN SHED BUYERS GUIDE
Choosing the right garden shed is an investment — not just in storage, but in your garden’s look, functionality, and value. With so many options available, it’s important to understand the differences in quality, materials, and design so you can make the best choice. At Rainbow Garden Buildings, we only build sheds designed to last: tongue & groove cladding and robust framing come as standard. Here’s what you need to know before buying.
1. Cladding Types – Why Tongue & Groove Matters
Not all sheds are built the same. The cladding (the outer panels) makes the biggest difference in strength, durability, and weather resistance.
-
Overlap Cladding (the cheaper option)
-
Thin boards simply nailed to overlap each other.
-
Leaves small gaps as wood moves, meaning wind and rain can get in.
-
Prone to warping and sagging over time.
-
-
Tongue & Groove Cladding (our standard)
-
Each board locks tightly into the next for a strong, weatherproof finish.
-
Provides superior protection from rain and draughts.
-
Rigid construction prevents sagging and keeps its shape for years.
-
Looks neat and premium compared to rough overlap.
-
At Rainbow Garden Buildings, we only use tongue & groove cladding because your shed should last, not leak.
2. Framework & Strength
A shed is only as good as the framework holding it together. Many budget sheds cut corners with thin, weak framing — they may look fine at first but soon twist, sag, or collapse under pressure.
-
Weak framing (common in cheap sheds):
-
Thin timber, often less than 28mm thick.
-
Can’t handle heavy shelves or tool storage.
-
Doors and windows quickly go out of line.
-
-
Rainbow Garden Buildings framing:
-
Thick, robust timbers for maximum stability.
-
Built to support shelving, bikes, tools, and garden equipment.
-
Reinforced design for long-term durability.
-
3. Roof & Floor Options
The roof and floor take the most punishment — from rain above and heavy items below.
-
Floors:
-
Avoid thin sheet board (common in flat-pack sheds).
-
Choose tongue & groove floors for strength under weight.
-
-
Roofs:
-
Good-quality felt is essential to keep water out.
-
Tongue & groove roofing boards prevent sagging compared to chipboard.
-
4. Security & Doors
A shed is often home to valuable tools, bikes, or garden furniture.
-
Look for:
-
Solid tongue & groove doors.
-
Proper bracing to stop warping.
-
Heavy-duty hinges and locks.
-
At Rainbow Garden Buildings, we build sheds with strength and security in mind.
5. Size & Use
Think carefully about what you’ll use your shed for:
-
Storage only? A smaller size may be enough.
-
Workshop or hobby room? Go bigger so you have space to move around.
-
Bikes, mowers, or large tools? Wide doors and reinforced flooring are essential.
6.Treatment & Maintenance
All wooden sheds require some care to last:
-
Apply a good wood treatment or preservative annually.
-
Ensure your shed is placed on a solid, level base (concrete or slabs are ideal).
-
Check the roof felt regularly for signs of wear.
With the right care, a Rainbow Garden Building shed will last for many, many years.
