How to make steps for a deck?

Unless you built a ground-level deck, you’re going to need steps to go with it. Check Building Regulations to see if you need to install handrails as well. It’s good practice to: Have a step tread width of 900mm – if you don’t want them that wide, they should be no less than 760mm Add a central step riser to stairs wider than 900mm to prevent them buckling Add a step depth (the vertical distance between each step) of between 150 and 180mm if building your own riser, so the steps are at a comfortable depth Getting started To build your steps for the deck, you’ll need: Step treads (the actual step themselves) Step risers Coach screws Deck screws Saw Drill Make the steps for your deck Make sure the ground where you want to put your steps is level and firm. If it’s not, consider laying concrete or paving slabs to provide a secure surface for your steps to sit so they don’t sink. Grab some joist off-cuts and cut them to the same width as your step treads. Attach them to the step risers at the top and bottom using countersunk coach screws. Place the steps against the sub-frame of the deck; if you’ve put slabs down for support, make sure the steps sit in the middle of them. The longest edge of the stair riser should be on the slabs, and the short edge against the deck. Drill pilot holes through the step and sub-frame joist, then screw the step to the sub-frame with more coach screws. After drilling pilot holes, screw the treads into the risers at each end with deck screws. If you don’t want gaps between each stair, you can add joist off-cuts or deck boards. Measure the height and depth of the gap, then screw the off-cut or board into the step riser with two screws at each end.

Wooden Decking in County Antrim

Wooden decking is an increasingly common option for creating outdoor seating areas in gardens. Due to the natural beauty of wood, they can be very fashionable areas which you can use year round with the help of external heating and lighting. Wooden decking is commonly fitted in locations in front of patio or French doors where they can create a smooth transition between inside and outside spaces. Wooden decking can come in any size or shape to accommodate any area. Curved designs or large areas linked by pathways can produce a stunning effect. Wooden decking is reasonably simple to install and causes little disruption, especially when compared to other possibilities like patio or paving. It could even be installed over the top of a pre-existing patio. It is crucial however to be sure that your wooden decking is structurally sound and able to take the weight of any furniture or plants that you want to use on the decking. There is a range of species of wood that can be used in wooden decking. Generally decking is made of hardwood, but there are softwoods available that fulfil the durability requirements. As hardwood decking will need maintenance, which generally consists of annual cleaning and staining for weather proofing, composite woods are becoming more popular for use in wooden decking because they are stronger and require far less maintenance.

FAQs

Unless you built a ground-level deck, you’re going to need steps to go with it. Check Building Regulations to see if you need to install handrails as well. It’s good practice to:

Have a step tread width of 900mm – if you don’t want them that wide, they should be no less than 760mm
Add a central step riser to stairs wider than 900mm to prevent them buckling
Add a step depth (the vertical distance between each step) of between 150 and 180mm if building your own riser, so the steps are at a comfortable depth

Getting started To build your steps for the deck, you’ll need:

Step treads (the actual step themselves)
Step risers
Coach screws
Deck screws
Saw
Drill

Make the steps for your deck

Make sure the ground where you want to put your steps is level and firm. If it’s not, consider laying concrete or paving slabs to provide a secure surface for your steps to sit so they don’t sink.
Grab some joist off-cuts and cut them to the same width as your step treads. Attach them to the step risers at the top and bottom using countersunk coach screws.
Place the steps against the sub-frame of the deck; if you’ve put slabs down for support, make sure the steps sit in the middle of them. The longest edge of the stair riser should be on the slabs, and the short edge against the deck. Drill pilot holes through the step and sub-frame joist, then screw the step to the sub-frame with more coach screws.
After drilling pilot holes, screw the treads into the risers at each end with deck screws.
If you don’t want gaps between each stair, you can add joist off-cuts or deck boards. Measure the height and depth of the gap, then screw the off-cut or board into the step riser with two screws at each end.

How much decking you need will – of course – depend on how big you plan your deck to be. There is an equation to help you work out how many deck boards you need. It’s a little complicated until you’ve been shown how it works, but once you know how to do it it’s easy to work out how much decking you need for any project. The equation takes into account the recommended 10% wastage and includes the expansion gaps that are required, which is between 5-8mm along the length of the deck boards (EGL, or expansion gap length) and 3mm along the ends of the deck boards (EGW, or expansion gap width) for timber. It also assumes you’re laying your decking horizontally, as if you’re looking for a diagonal or chevron design you’ll need more deck boards. Let’s go through an example, assuming you have a 10m x 6m area that you want to cover with decking made from timber boards that are 2.4m long and 144mm wide. We’ll use the EGL of 5mm and EGW of 3mm.

Calculate the surface area for your decking Multiply the length (L) of your decking area by the width (W): L x W = Decking Surface Area (DSA) in m² 10 x 6 = 60m²
Work out the coverage of your deck boards Add your deck board width (DBW) to the expansion gap length (EGL), then add the deck board length (DBL) to the expansion gap width (EGW). Then multiply these numbers. (DBW + EGL) x (DBL + EGW) = Single Board Coverage (SBC) 0.144m + 0.005m = 0.149m 2.4m + 0.003m = 2.403m 0.149 x 2.403 = 0.358m²
Calculate the number of deck boards you need Multiply the SBC by 1.1 to allow for 10% wastage. Then, divide the DSA by the SBC. DSA / SCB x 1.1 = Total number of boards required 60m² / 0.358m² x 1.1 = 184.36 boards – so round up to 185 so you’re not left short.

If that all seems a bit complicated for you, let a professional do the maths – they will be able to give you an idea of how much decking you’ll need in no time.

You might think that building decking on a slope is a no-go, but it’s actually a great way to help you make use of your garden when the ground is sloping. It will provide you with a level surface that you can BBQ on as well as dine alfresco without finding that your meal is rolling down the table. But how do you build decking on a slope? Our guide in the FAQ above, ‘How to build a raised deck’, is the perfect solution – but we’ll break it down here if you just want to get an idea of what’s involved. Dig out the area If you’re laying on soil or turf, you’ll need to dig it out. Dig down and remove all the turf from the area and ensure that there are no weeds or stones in the area you’re going to build your decking on. Since you’re building on a slope, it will be hard to get it level, but dig out to a depth of 50mm and lay weed-control fabric with gravel over the top. Add posts and set with concrete Make holes for posts and add them in, ensuring they’re longer than you need. Make sure they’re level, then fill the holes with a concrete mix to set them in place. Build the outer frame Make sure you always work at the top of the slope when you’re building your decking, and measure where the highest point of the decking will be. Secure the 4 sides of the outer frame and factor in a 2mm fall for every metre of decking so rainwater can run off. Add joists Secure joists along your frame at 400mm intervals. If you get to the last joist and there will be more than a 400mm gap left at the end, add in an extra one for support. Lay your deck boards Screw your deck boards to the joists, ensuring that the deck boards are running in the opposite direction to the joists. For timber boards, you need to make sure you leave an expansion gap of 5-8mm. These steps should give you an idea of whether you want to have a go at building decking on a slope, or whether you want to leave it to the pros.

Usually, slipperiness is caused by algae or dirt on top of the deck or terrace. A full cleaning treatment should restore the natural grip of the wood or stone. If slipperiness is a persistent problem, consider installing grip mats in high traffic areas of the deck.
