- 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
- 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 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
Installing wooden flooring is a quite simple process, however to get it right the first time, there are very essential preparations that must be made. These includes determining the site is in the best condition before installation, removal of all floor coverings and underlay for a more stable and durable installation and incorporation of the right expansion gap of about 10mm to 12mm which would be maintained around the floor’s perimeter.
Wooden floor fitting can be done on two types of sub-floor - Concrete and Plywood. To install onto concrete, you can follow the guide below:
• Incorporate flexible wood on concrete adhesives.
• With the help of a 3mm toothed trowel, spread above 2 board widths of adhesive along the starting wall sub-floor, beginning at a corner of your room.
• Position the first row of flooring into the area that is glued using the tongue facing opposite the wall.
• Put 10mm spacers against the wall to see to the consistency in expansion gaps.
• Make sure the joints are at a minimum of 150mm apart from the first row when fitting the second row.
• Utilize pre-cut smaller boards if you’re to start a new row with staggered joints.
• Continue with this nailing method and make sure the 10mm expansion gaps are consistent around the floor’s perimeter.
To install onto plywood, you can follow this guide:
• Make use of a porta-nailer.
• Position 10mm spacers against the wall - parallel with the installation direction.
• Fit the first row using the tongue facing opposite the wall and with the help of the porta-nailer or flooring nailer.
• Lay the second row and make sure the short end joints are at a minimum of 150mm apart from that of the first row.
• Utilize pre-cut smaller boards if you’re to start a new row with staggered joints.
• Continue with this nailing method and make sure the 10mm expansion gaps are consistent around the floor’s perimeter.

- 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.
- 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.
Considerations
If you're thinking about making changes around your household that include working with wood, you ought to hire a local carpenter. Looking to fix a loose piece? Or looking for some drastic improvements? A carpentry expert might be the top choice.
General carpenters are expert woodsmen and know a variety of areas from grounds to gear. Maximum carpentry depends on a rudimentary set of skills which your worker may choose to build upon by specialising. For example, few carpenters have a talent for wood repair, building original constructions or manufacturing furniture.
Time
The extent of time it takes to complete a certain project is another consideration to be kept in mind. This is particularly essential if you are on a constricted timeline or dealing with time limitations. Most carpentry projects take about 13 hours to finish. Although, this is purely dependent on the intricacy of the project and the pre-arranged timeline you and your carpenter agree to.

- What you need the shed for
- How much space you have
- How big you need the shed to be
- Which style of roof you want
- What material you would like
- How big your budget is
- Hand-crafted from Nordic White Spruce
- Felt roof reinforced with high-grade polyester
- Tongue and groove cladding makes it more weatherproof so ideal for items that must be kept dry
- High eaves for more head height and to store taller items
- Pent roof and fixed windows allow lots of light
- Ideal for putting up against a wall or fence
- Door can be hinged either side
- Ideal for small gardens or those with fewer tools to store
- Apex roof for water runoff
- Tongue and groove walls
- Tall floor-to-gable door
- Plan your shed base
You must have a sturdy base for your shed, otherwise the frame won’t stand properly and could stop the door from opening. Decide whether you’re going to have:
- A concrete base laid on hardcore
- Concrete slabs on sharp sand
- Treated wood beams on hardcore or shingle
- An interlocking plastic system
- Treat wood with preservative To help your shed last as long as possible, you should coat all the wooden parts with timber preservative before you put it together.
- Put the shed floor together Some will need more assembly than others, but you need to make sure that the floor panel is attached to the joists; follow the manufacturer’s instructions for the correct spacing.
- Put up the shed walls
- Mark the centre point of each wall on its bottom edge, then do the same for the shed floor so you can line them up together.
- Stand the gable end on the base and line it up. Check that it’s vertical with a spirit level – you might need someone to support the panel while you do this. Use a temporary holding batten to keep it in place.
- Fix a side panel to the gable end panel with countersunk screws, then add the second side panel in the same way.
- Fit the roof
- If the shed comes with a support bar, put this in position before you put the roof panels in.
- Nail the roof panels in place, ensuring there’s a parallel and equal overlap at each end.
- Roll out some roofing felt from front to back, leaving a 50mm overlap at each side. Secure it with clout-headed felt tacks at 100mm intervals.
- Apply mastic sealant to the outside corners, then fix each corner trim with 30mm nails.
- Add the fascias and finials, predrilling 2mm holes to avoid splitting the wood. Nail them through the felt into the shed using 40mm nails.
- Add the shed windows
- Slide each windowsill into the tongue and groove cut out, then put the window cover strip in position, fixing it to the vertical framing.
- From inside the shed, put the glazing sheets into the window rebates, making sure the bottom edge of the glazing sheets sit on the outside of the sill.
- Fix the window beading on the top and sides with 25mm nails.
- Fix the walls to the floor Before you do anything, make sure you check that the centre marks on the walls line up with the marks on the shed floor. Then fix the wall panels to the floor with 50mm screws, aligning them with the joists. And that’s it! But if you’re not confident in building a shed yourself, there are plenty of professionals available who will be happy to help.
