- 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.

How much do Carpenter services cost?
Do you have a need for a carpenter in or around your house? If yes, then one of the first things you’d probably want to know is the exact amount it would cost to get the project over the line. Now, carpenters are skilled craftsmen that are able to make things with wood and fabricate all sorts of wood constructions. The price charged by carpenters are determined by a wide range of factors which makes it nearly impossible to provide a short and accurate estimate without having a look at your unique requirements. In this post, we’re going to give you an in-depth insight into general carpentry charges while also considering some of the influencing factors. Let’s take a look!
Some of the most common factors that determines the price charged by a carpenter includes the project type, the size as well as scope of the project, the location of project, ease of access, experience and qualification of the carpenter and lots more. For instance, if the job is a minor one such as building a shed, it’ll cost a lot less than something more complex which requires a bit more experience like constructing a staircase. In general, building a shed will have a labour cost within the range of £150 to about £250, while a staircase construction will require a labour cost in between £1,000 to £1,500. For general carpentry, you can expect to pay within the range of £20 to £30 hourly rate depending on a number of factors which are stated above. It’s also important to state that while some carpenters charge per hour, others by the day and several of their projects will be charged at fixed prices.
The table reveals the kinds of work that Carpenters normally do and also the regular cost range of these jobs. Some tasks take longer to finish than others so costs do differ by task.

Carpenter FAQs
- 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
- Step treads (the actual step themselves)
- Step risers
- Coach screws
- Deck screws
- Saw
- Drill
- 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.
Two of the commonly used terms in the UK and Irish construction industry is “First Fix and “Second Fix First fix encompasses all the work required to take a building from foundation to stroking plaster on the interior walls. This comprises of building walls, floors and ceilings, and implanting cables for electrical supply and pipes for water supply.
Some claim that First Fix starts after the shell of the building is complete, and ends when the walls are plastered. Some of the elements in the first fix are as follows.
• Drain runs: must be downhill and straight
• Spare conduits: drawstrings
• Soil pipes
• Copper pipes
• Normal pipes
• Doorbell
• Door frames
• Pocket doorframes
• Stairwell
• MVHR (mechanical heat recovery ventilation runs)
• Push-fit or other plastic piping
• Electrical back boxes
• Electricity cable runs
• Telephone, data and audio-visual cables
• Socket location
• Security
• Fire alarm
• Sound insulation
• Plasterboarding
It is to be kept in mind that the list goes on as there are several things that you can do when you are building a house from scratch and it is impossible to cover each and every aspect in detail.
The second fix includes all the work after the plastering of a complete house. These include linking cables to the electrical fittings, coupling pipes to the baths and sinks and fitting doors into doorframes. Second fix work requires a tidier finish than the first fix.
Carpenters, electricians and plumbers get a proper idea on the division of work. They will also be able to visit the construction site at different times.
Project managers can simply report it as the "first fix complete" or "the second fix 50% done" and others would very easily understand.
Regardless of the fact that a construction company might specialise in a certain form of fix, be it the first or the second, they are obligated to have a rudimentary understanding of both and are required to perform them from time to time.
- Mark out the area and dig the top layer of soil, trying to get the ground as flat as possible.
- Build a timber frame to size.
- Measure out 4 rows of 3 blocks to create good weight distribution and lay in place.
- Underneath each block, dig around 50mm wider than the blocks and about 150mm deep. Fill the hole with pea gravel until it’s flat.
- 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.
- Nail your timber shed base to the timber planks to create a sturdy base for your shed.
- The shed doesn’t cover more than 50% of the garden
- It’s not in front of your house
- The shed is single-storey with eaves no higher than 2.5m and the overall height is no taller than 4m for a dual-pitched roof, or 3m for any other type. If it’s located within 2 metres of your property’s boundary, it mustn't be more than 2.5m high
- There’s no veranda or balcony
- The floor area is no bigger than 15m2 - up to 30m2 may be covered under Permitted Development if other conditions are met
- The shed is for domestic use only by those who live in the property and there’s no sleeping accommodation – that means you can’t run a business from the shed unless you apply for planning permission
- If you live in a listed building, you’ll need Listed Building Consent before you can build a shed in your garden
- If you live in a conservation area or similar, the maximum area of ground covered by outbuildings, pools and enclosures situated more than 20m from any wall of the house mustn’t exceed 10m2 if they’re to be considered as a permitted development
- If you own a piece of woodland, you must seek planning permission for any permanent structure
- In Scotland, you’ll need planning permission if any part of the shed comes within 1m of a neighbouring property or is more than 2.5m high
- In Northern Ireland, there are rules about how close your shed can be from a road that passes by the back of your house. It’s best to check for clarification
Yes, your shed does need a base. This is to give it a solid, level foundation. Open soil will not help with the longevity of the shed itself or the contents within. The best materials to use to make your shed base are concrete, natural stone or wood.
- Tongue and groove timber boards
- Boards for the ledges and braces, at least 20mm thick
- Nails
- Hammer
- Saws, including a circular saw
- Chisel
- Mallet
- Cut your boards to size If you can’t buy boards at the right height and width for your door, cut the boards to length using a circular saw. Don’t forget to sand and treat any cut ends with timber preservative. Lay out the boards in the best arrangement for your shed door, with the inside of the door facing up.
- Arrange the ledges and braces On most shed doors, you’ll probably need 3 boards across the back of the door to form the ledges. The ledges keep the door straight and keep the boards of the door together. The braces are the parts of the door that slope down to form a ‘Z’ shape between the ledges. Ensure that the braces are sloped up from the bottom and middle hinge to stop the door from sagging as the timber expands and contracts in the weather. Once you’re happy with the arrangement, mark the spots on the boards where they will meet and cut out of the housings using a chisel and mallet.
- Put the door together Use clamps to pull the boards together and hold the ledges and braces in place. Nail from the front of the door through the boards and ledges to fix them. Secure the ledges and braces with screws; you may want to pre-drill and countersink holes to prevent the wood from splitting. Remember to treat them with preservative if you do.
- Fix the shed door hinges Make sure you measure carefully before attaching the hinges, ensuring you know where the pin sits in relation to where the door opens.
- Treat the door and add locks and handles Apply some wood oil, like linseed or teak oil, to help prevent water damage. Then add locks or handles to your shed to help keep it secure. If you’d rather leave it to the professionals, there are plenty of specialists that will be able to make a shed door for you, or even put up an entire shed.
