How much do Builder services cost?

How much do Builders cost? Prices for Builders in 2026 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.

Builder FAQs

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.

how much is a dormer loft conversion?

Are you considering a dormer loft conversion for your home? If yes, then you’d probably want to know how much it costs. Unfortunately, due to the several variables and influencing factors, a precise answer can not be provided for all dormer loft conversions. In this article we’ll give you a vague idea of the general cost so you can set a more realistic budget and start planning.

There are three main types of loft conversion which includes the Velux, Dormer, and Mansard. Out of the three types, the dormer happens to be the most common type and possesses a small flat roofed extension with a window. The dormer loft conversion will usually cost within the range of £25,000 to £30,000.

The price for a smaller dormer loft conversion, mid range dormer loft conversion and large scale dormer loft conversion will be at £2,000 to £7,000, £10,000 to £30,000 and £40,000 to £60,000 respectively. However, you should take note that the prices given are all based on varying influencing factors such as the type of installation that is selected, the type of the rood, en suite conversion as well as other customization. Changes in price can be as a result of the materials required and the extra time per labour that’s needed to complete this home improvement project by the tradesmen employed.

Furthermore, a dormer loft conversion average cost will also depend on the type of dormer you opt for. Here is a list of the most common applications:

✓ Blind dormer loft conversion - £3,200 to £4,400

✓ Recessed dormer - £1,300 to £1,850

✓ Barrel roof dormer - £3,000 to £4,600

✓ Gable dormer - £5,500 to £7,500

✓ Hipped roof dormer - £5,600 to £6,660

✓ Pedimented dormer - £12,700 to £23,100

✓ Flat roof dormer loft conversion - £13,800 to £21,600

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.

What kinds of loft conversion are there?

There’s a huge range of different types of loft conversions. The most common are dormer and skylight or Velux conversions. There are also hip to gable and mansard conversions. The type of loft conversion that’s most suitable for your property will depend on the style of roof and the size of your loft.

How much plasterboard do I need?

How Much Plasterboard Do I Need?

Although many people especially contractors have a tough time estimating the number of drywall or plasterboard needed to complete a project, it’s a rather simple task if all factors are taken into consideration. If you’re able to follow the same procedures taken by professionals to count dry wall sheets, you’ll be in the right direction. Let’s have a look at the procedures to follow!

lTake Square Footage Measurement

• Measure the square footage of the area where the plasterboard will be fitted.

• Multiply the height by the width of each wall or ceiling area.

• Add all quantities to obtain a total square-foot amount.

lCalculate Drywall Sheets

• To calculate the number of drywall or plasterboard sheet is very simple once you’ve gotten the total square footage.

• To get started, simply divide the total square footage of area by 32 (that’s if you are using a 4 by 8 sheets) or you can also make use of 48 to make the division (only if you’re making use of the 4 by 12 sheets).

• The answer you get after the division will give you the full number of plasterboard sheets that’s required to complete the project.

We’d recommend you include an extra 10 to 15 percent of whatever you calculate to take care of the possible odd cuts and wastages. This implies that if your total area is 1600 square feet while incorporating 4 by 8 sheets, simply divide 1600 by 32 which equals 50 sheets, now take 10% of 50 which equals 5, then add back the 5 extra to the 50 sheets earlier calculated to get 55 sheets. If you wish to estimate the cost, simply multiply the number of sheets gotten by the price per sheet. Do not forget to include delivery charges and local taxes.

What types of extension are there?

There are many different types of extension. For example, you could install an orangery, flat or pitched roof extension, over-structure extension, single or double storey extension or a glass box extension. Which one of these is most suitable will depend on your existing property.

how deep do footings need to be for a porch?

No matter how big or small a building is, it can only be as good as it’s foundation - and that’s a fact! It all starts from the footing and when it isn’t deep enough, unlike badly installed gutters or gapped hardwood flooring, can make the whole building collapse to the ground. Just like any code recommendations, the depth of the footings of your porch is a parameter that must be complied with and adjusted to suit your local code requirements.

As a rule of thumb, you should always dig below the frost line when excavating your footings. At this depth level, the moisture present in the soil will be frozen. Ultimately, this will help the ground to act as a barrier to insulate the soil below the footing from freezing during the cold months. As a result, in regions where the weather is almost always very cold the depth of your footings is expected to be at least 48 inches. But in areas featuring a warm climate, you may be allowed to install your footings on grade.

In addition, it’s compulsory that your footings must be installed at a minimum depth of 12 inches below unsettled soil. However, if you’re constructing the structure into a steep hill’s side or by the side of a retaining wall, it’s required that you maintain the least distance to grade both vertically and laterally. In the event whereby you need to achieve a good lateral barrier, you’ll need to have your foundation dug a lot deeper compared to if it’s on a flat surface. For a more accurate and updated information, you can consult your local building inspection department to get familiar with the requirements in your area.

how to refurbish your house?

If you’re thinking about refurbishing your house or property but don’t know how to go about it, then you’ve come to the right place. In truth, not every home refurbishment works goes in exactly the same order, however it’ll do you some good to abide by a specific plan in order to avoid both unnecessary works as well as expenses. For instance, how would it feel if you have already closed walls and paint only to realize that there’s a need to include a new plumbing stack that has to go behind the wall? Not good, right? Well, this guide is designed to help you avoid such frustrating situations. Let’s have a look!

✓ Establish a plan. This involves carrying out a good assessment of what you’d like to refurbish and set the priorities like deciding where to start and making sure you have both the time and budget to complete the project.

✓ Set a budget. Establish a final amount that’ll be the threshold to your spending. It’s always good to add an additional 10% to 15% to cover unexpected costs.

✓ Hire a contractor. Carry out a research, reach out to many contractors, compare their prices, work quality as well as integrity before hiring.

✓ Talk to your insurance company. Find out if you have the amount of coverage that suits your needs from your insurance company before and after your project.

✓ Work behind the walls. This include doing all the works necessary behind the walls like plumbing, electrical, heating etc.

✓ Paint and install flooring

✓ Fit in the cabinetry
