How much do Builder services cost?

How much do Builders cost? Prices for Builders in 2025 can fluctuate relying on the sort of work that you need to have carried out in your residence.

Are you planning to erect a new house or structure? If yes, then you’d probably want to know just how much it’ll take to get the project over the line to help you set a budget and start to plan. Building a new house is requires huge financial investment and as a result, there’s the need to carry out your due diligence before you proceed. In this post, we’re going to give you an insight into the prices charged by builders to erect a new home or structure.

First and foremost, like every other home project, the price charged by builders to construct a new house or structure depends on a wide range of factors. These factors include the size, location, accessibility as well as qualifications of the builders you wish to employ just to mention a few. For instance, you’d expect the cost of building two-storey in London to be a lot more expensive than the price of a one-story building in Scotland. However, we’ll try our best to give you an idea of the price range you can expect to incur to complete your project.
In general, a builder will charge within the range of £10 to about £15 per hour on the average. For small building projects which includes wall and foundations repairs, a builder will typically charge about £11 per hour. However, the price charge will depend on the extent of the job due to the fact that simple tasks such as repointing only costs about £10 per hour, while laying new foundations can cost up to £15 per hour.

The table shows the types of work that Builders typically do and the average cost range of these tasks. Some tasks take longer to finish than others so prices do fluctuate by job.

what is a dormer loft conversion?

A dormer loft conversion is a type of loft conversion that’s built making use of a roof’s existing slope.

how to tile a porch roof?

Tiling a porch roof is a very important but laborious and difficult task. A project of this magnitude will require a large investment in planning and preparation way before the actual installation process takes place. It can be a brand new porch roofing tile or a replacement of the existing one, either way it’s crucial to get the right technique. If you lack proper training or experience in this field, we’d recommend you hire the services of a reliable professional probably within your local area to guarantee the best results and to save yourself some time and money. This guide will give you a good insight into the porch roof tiling process. Let’s have a look!

• With the crown looking upwards, put the first tile on the batten and centre the tile from side to side.

• Hammer a 10d nail at the base of the tile and into the batten (make sure not to overdrive the nail).

• To provide a much needed support, apply a little mortar under the first tile.

• Identify the inner end of the first tile and place another tile on top. Take a measurement from the outer end and adjust the end of the second tile to fit.

• Just like you’ve done with the first tile, nail the second tile into the batten.

• Position two tiles at the both ends of the ridge and proceed with the installation just as you’ve done with the previous tiles.

• Take a measurement of the distance across the ridge from the first tile’s outer end. Once done, you can then calculate the number of tiles required by subtracting 16 inches from your measurement and divide the answer by 8.

• Beginning at the second tile on one end of the ridge, install the half the number of ridge tiles towards the centre of the ridge. Now install the remaining tiles working from the opposite end to the ridge’s centre. At the centre of ridge should be a key tile with mortar.

How to plasterboard a wall?

How To Plasterboard A Wall

If you’re looking to plasterboard your wall, one of the essential things to have in mind is that the plasterboard must be hung horizontally and not vertically. Due to the way they’re manufactured, plasterboard sheets normally possess a “grain along the length. This implies that, it’s only when they’re firmly placed perpendicular against the wall that they’re able to achieve their maximum strength. Materials you’ll need to complete this task includes: Tape measure, stanley knife, pencil, spirit level, drill driver or screw gun, surform, drywall screws and handsaw. Now let’s have a look at the wall plasterboarding steps!

• To plasterboard a wall the first step to take is to place each board in such a way to make the edges the centre of the noggins and upright. Also, the the adjoining walls and door openings should fit closely to the edges.

• Work from the door opening to the ending wall. From the the stud’s edge to the noggin’s centre, use your tape measure to measure a cut board and as a rule to mark up.

• Place your spirit level on the marks and use the Stanley knife to run a line along the intended cut. Once done, turn the board on its edge and give a sharp push on the back to split.

• Cut the paper left with the knife after folding the split edge back on itself. This way, you should get a nice and clean edge.

• In its right position, place the board up against the studwork. Install the screws on the board’s edges where a noggin or upright can be seen.

• Mark lines down across the board at the stud’s centre.

• Cut the end boards to length.

• Install the remaining boards as mentioned above. While doing this, make sure the factory edges are together.

• Cut any board extending into an opening and finish the edges using a surform.

We’d recommend you hire the professional services of a plasterer for the best results especially if you lack the necessary training or experience. Plasterboarding a wall can be a tricky challenge and you’d save yourself some time, money and effort by getting it right on the first trial.

how thick should render be on external wall?

Render serves two basic functions. One is it’s protective qualities as render acts as waterproof for the wall which enables them breathe by allowing water vapour move from the inside to the outside of the structure while also working to prevent water or rain from finding its way inside the structure. While the second function is the decorative qualities as render is able to provide the structure with a fine finish and colour to make the building a lot more appealing and correcting faults in line and level in the masonry.

If you wish to apply render on your external wall, you’d probably be wondering just how thick the render should be to perfectly serve both of functions. In this article, we’re going to take a look at just that!

For a render thickness, the British Standard Wind Driven Rain Index has come up with 4 ratings which include Sheltered, Moderate, Severe as well as Very Severe. An area with Very Severe rating include South West England. This rating implies that the thickness of the render in this area should be increased to at least 20mm for a direct one coat render applications as well as 5 to 6 external wall insulation base coat applications. And if you happen to reside within one mile of the coast, it’s strongly recommended you incorporate an extra repellent protection like Paraguard AG from Parex.

In general, render that’s prepared on site with cement and sand should be have a minimum of 20mm to 25mm thickness. Although, it should be noted that the quality of the render is based on quality of the sand incorporated, the design mix as well as being largely dependent on how good the mixing technique from the applicator is. The most common reasons why traditional renders fails is due to both poor mixing ratios and low quality materials used.

They’re the perfect investment for those looking to expand their space without having to carry out huge extension projects which normally consumes both time and money.

Garden rooms are best built by professionals to guarantee the best results. However, if you feel confident enough to undertake the project, then this guide will give you an idea of the process.

✓ Build the foundation. Here you can build the foundation using concrete, but in cases whereby there are root systems closeby then you can make use of low impact screw piles.

✓ Start the construction process with timber frame, SIP panels as well as other modular components and materials

✓ Once you’re done with the construction process, the next course of action will be to develop and position the roof structure on to the top of the newly constructed garden room. Here, you can also decide to use sun pipe and solar heating or PV panels. You can also protect the construction from the elements by making use of cedar cladding.

✓ Doors installation. The best type of doors to use here are draught sealed doors which can also be treated hardwood or powder coated aluminium .

✓ Make the finishing touches here and there and make sure all connections are complete.
