Garden Sheds in Portstewart

Garden sheds are a significant factor of any useful garden space. They provide storage for heavy garden tools, as well as for other equipment. A large shed may provide enough room for plant potting or a general workshop. Alternatively, a substantial shed could be utilised as an inside seating area. Garden sheds come in a huge range of sizes and can be specified to your particular requirements, giving you full control over the amount and position of windows, type, size and location of door, and design of roof. Garden sheds generally are available in one of three materials. Wooden sheds are the classic design and can be integrated well into any garden creating a natural look, especially if the wood used for the shed is matched to bordering fences. Wooden sheds remain very popular, although they will demand maintenance by retreating or staining the wood to protect the lifespan of the shed. Garden sheds are also constructed from metal, which is very tough and therefore ideal for storage of tools and other equipment. Metal sheds also require hardly any maintenance. The final material for garden sheds is plastic, which in modern examples is a lot more durable than might be expected. When contemplating a garden shed, it's critical to ensure that you select one that will fit in your garden space. Garden sheds should be placed on a flat area, and will require a base to be built as a foundation. This base could be produced from either concrete, paving, gravel or a floating wooden base, but will have to be the right size for your shed and capable of supporting the weight of your shed when loaded.

FAQs

How to build a shed base?
You need a firm, level base for your shed to ensure that it stays structurally sound – without one, doors will sag, walls will lean and it won’t last you as long. But how do you build a shed base and what should you make it from? Timber shed bases A timber shed base is made from pressure-treated timber and has metal spikes that you hammer into the ground to keep it in place. You can often buy them with your shed installation kit, but they also come separately, often in 6x4 or 7x5 sizes. To build a timber shed base, you’ll drill holes then fit screws in the timber until the entire frame is built. Remember to check it’s square, then fix L-shaped feet to the inside of the frame. If you’re putting your shed on a hard surface like concrete, this is all you need to do. If you’re putting the base on soft ground, hammer in spikes at each corner until they’re level with the top of the base, then secure the spikes to the base with screws. Then you can position the shed floor onto the base. How to build a plastic shed base A plastic shed base is a simple and quick way to build a shed base. You can lay it on level concrete or paving slabs, but adding sharp sand on top will help keep it more secure. They come in a kit containing plastic grids. To build your plastic base, first measure out the site and hammer a peg into each corner and tie with string or builder’s line. Make it slightly larger than the shed base to help with drainage. Then cut into the lawn and remove the turf, making sure it’s level. Lay down a membrane sheet and weigh it down if it’s windy. Then lay out the number of plastic grids you need, then remove the locking pins and clip all the grids together. Once they’re all connected, put the locking pins back in the centre of the grids. Put your shed floor on top and you’re done! Concrete or paved shed bases For a concrete base or a shed base made from paving slabs, you’ll need to dig a sub-base. For concrete bases, you’ll need to dig down 150mm so you can add 75mm of compact hardcore under 75mm of concrete. For paved shed bases, you’ll want it to be about 120mm deep for 50mm of compact hardcore and the paving slabs.
  1. How to build a shed base out of paving slabs
    • Mix sand and cement together to make mortar or use a pre-mixed one
    • Use a trowel to lay mortar for 1 slab at a time on the sub-base and lift a damp-sided slab onto the mortar, using a piece of timber and club hammer to tap the slab into position carefully. Continue to lay the first row of slabs
    • Make equally-sized spacers in all the joints in the slabs to ensure they’re the same size, checking it’s level as you go along
    • Next lay slabs along the two adjacent outer edges, filling in the central area row by row
    • Leave the mortar to set according to the instructions or for at least 48 hours before filling in the joints with mortar or paving grout
  2. Building a shed base from concrete
    • Create a wooden frame around your shed base area (also called formwork) to stop the concrete from spreading
    • Mix pre-mixed concrete with water or use 1 part cement to 5 parts ballast
    • Wet the sub-base using a watering can with a rose on the end
    • Pour the concrete onto the framed base starting in one corner
    • Push the blade of a shovel up and down in the edges of the concrete to get rid of air bubbles
    • Use a rake to spread the concrete, leaving it around 18mm higher than the top of the frame. Work in sections of around 1-1.m2
    • Compact the concrete using a straight piece of timber that’s longer than the width of the base. Move the timber along the site, hitting it along at about half of its thickness at a time until the surface is evenly ridged
    • Remove excess concrete and level the surface by sliding the timber back and forwards from the edge that you started. Fill in any depressions and repeat until even
    • Run an edging trowel along the frame to round off exposed edges of the concrete and prevent chipping
    • Cover the concrete with a plastic sheet raised on wooden supports to allow slow drying. Weigh it down with bricks
    • Once the concrete is set, you can install your shed and remove the wooden frame with a crowbar

How to felt a shed roof?
Whether you want to felt a new shed roof or you’re re-felting your existing shed roof, it’s simple when you know how. Read our quick guide to see how easy it is.
  1. Remove any existing fascia boards Remove the fascia boards and the old felt if you’re re-felting.
  2. Measure the shed roof Measure the roof, taking into account that you should leave around 50mm for overlaps at the eaves and 75mm at the gable ends. You’ll probably need 3 pieces of felt, but some smaller sheds only need 2.
  3. Apply felt to the roof Once you’ve cut the felt to size, apply the each piece to the roof, pulling it tight. Then nail along the length of the roof at 100mm intervals. For nails at the bottom edge, they can be wider – around 300mm. If you’re adding a piece of felt in the middle of the shed along the apex, fix it using adhesive, then nail it at the lower edge at 50mm intervals.
  4. Tidy up the overhangs Fold down the felt at each overhang and nail it securely. Cut a slit in the overhang at the apex using a pen knife, then fold that down and nail at 100mm intervals along the gable. If you like, you can add fascia boards to keep the shed looking neat. Use wood nails to secure them and then trim away any excess felt.
That’s it. It sounds scary, but it won’t take you long to felt your shed roof as long as you follow instructions carefully.
How to build a shed base on uneven ground?
Building a shed base on uneven ground can be as easy as digging out a sub-base and checking that it’s level. You can dig down until the soil is light brown and rather compact, then work out where the ground is uneven and move soil around to compensate. Add a weed-blocking membrane down then put plastic grids in to act as your shed base or continue to make a sub-base for paving slabs or concrete. However, you could also build a timber shed base on uneven ground using concrete blocks to level it out.
  1. Mark out the area and dig the top layer of soil, trying to get the ground as flat as possible.
  2. Build a timber frame to size.
  3. Measure out 4 rows of 3 blocks to create good weight distribution and lay in place.
  4. Underneath each block, dig around 50mm wider than the blocks and about 150mm deep. Fill the hole with pea gravel until it’s flat.
  5. Place timber planks along the rows of blocks and see how level it is. Add or remove blocks where necessary. If it’s only a small difference, use shingle underneath the timber until it’s level.
  6. Nail your timber shed base to the timber planks to create a sturdy base for your shed.
If you’ve got any questions about building a shed base on uneven ground, it’s best leaving it to the pros. Get in touch with a range of builders who will be able to offer you a quote.
How to dismantle a shed?
It can seem daunting to dismantle a shed when you want to get a new one or just get rid of it for good. Every shed is different and is likely to have been put together in a different way, but there are some general rules that you can follow to make dismantling a shed a simple task.
  1. Remove fascias and trims Unscrew or prise off the screws and nails fixing the trims and fascias to your shed.
  2. Take off doors and remove windows Unscrew hinges from doors and take them off. Remove all metalwork once the door is off. If you’ve got frames on your windows, unscrew these, and remove the panes. Be extra careful if your windows are made of glass.
  3. Take off the roof Prise off the tacks from the roofing felt and take the felt off – you can’t reuse it, so you’ll need to throw it away. Unscrew the screws on the roof boards and slide them off the shed’s frame – you might need a friend to help you do this.
  4. Take out the roof brace (optional) If your roof has a brace, unscrew the brackets that hold it to the side of the shed. Remember not to lean on anything once you’ve taken the brace off as the walls might be wobbly.
  5. Unscrew the frame from the floor Remove all the screws that are holding the shed to the base, remembering not to lean on the walls.
  6. Unscrew the frame corners Starting at the corner of the front gable, remove the screws where the panels meet. Once a panel is free, lift it carefully out of the way so you can carry on with the others.
Tidy up all your tools and debris, clearing the area to make it safe, and you’re done!
