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.

Builder FAQs

Why has my driveway cracked?

Driveway surfacing materials like concrete, asphalt and clay brick usually crack because they’ve been exposed to extreme temperatures or put under high pressure. It’s important to repair driveway cracks before they get worse and cause damage to vehicles and perhaps others to trip on raised cracks.

how much is a double house extension?

A double house extension is basically a construction to any aspect of your house that elevates up to offer two floors of space. It can be structured to suit your existing home in two storeys or as a side wing on a taller property. If you’re considering building a double house extension, then estimating the cost is a very important task to do before commencing the project. In this article, we’ll give you an idea of the cost of a double house extension so you can estimate yours accordingly.

The double house extension cost depends on several factors that’s specific to your home as well as your design choice. These includes:

• Location of your property. Places like London and the southeast will generally cost more than the other regions due to higher demands.

• Accessibility of the site. The ease of your site’s accessibility also plays a key role in the price.

• Size of the extension. The more the extension’s size in footprint and square metres, the higher the possible costs.

• Materials used in making the roof as well as the complexity of the roof design.

• Your choice of finishing. These includes flooring window and door frames, glazing, underfloor heating and roof lights.

• Your property’s soil type. Different types of soil requires varying treatments as well as materials to develop solid foundations.

Constructing a double house extension is a quite simple build in terms of technicality when its to the side or rear of your house as this can also help you save some money. Generally, considerably expanding your home’s space by building a double house extension will cost within the range of £1,500 per m2 to about £2,800 per m2.

can you render a house in winter?

Aside from the cold weather not being the most pleasant condition to work in, the winter weather can also cause a lot of problems for construction workers and even more so when you’re working with render. Poor weather conditions can generally cause a lot of harms on the final finish of a render. Below are some of the reasons why you should not consider rendering in a bad weather.

✓ Lime bloom. Render can be impacted by lime bloom as they are subjected to damp conditions and low temperatures while curing. This is due to the fact that cement are intolerant to slower drying conditions especially immediately affect its application.

✓ Top coats can be compromised. Coating are likely to get washed off before they’re even afforded the chance to set if drying conditions are low.

However, because its cold out there doesn’t necessarily imply that work must stop. It’s very possible to render during the winter months but to avoid potential pitfalls, we’ve got some tip that can be of great help. Let’s have a look!

✓ Check the weather forecast. Determine the drying and curing time and watch the forecast for the temperature dropping at night.

✓ Select the most suitable render. There are renders that are suitable for application in low temperatures to about 5℃ or even as low as 1℃. These types of render are fast setting which makes them perfect for the cold condition.

✓ Watch out for frost. Frost and render are enemies. Therefore, it won’t be wise to work with frosted materials, on frosted subtrates or apply below the recommended temperature that’s written on the product’s datasheet.

✓ Protect the finish. Make use of artificial enclosures around the scaffolding to battle adverse weather conditions.

how to lay loft boards?

How To Lay Loft Boards

Do you need more storage space in your home or property? If you live in a tiny space especially where extensions can’t be made sideways, why not look to the topmost area of your home and consider boarding out your loft to make it usable?

Boarding your loft can make for a fairly easy DIY project but like every other home improvement tasks, it requires some specific skill sets as well as knowledge for a successful construction. Therefore, we’d recommend you hire the services of a reliable professional in order to guarantee the best possible outcome, especially if you lack proper training or experience that’ll help you avoid some costly mistakes. Here, we’ll give you a good insight into the loft board laying procedures.

• Get The Right Tools & Equipment

The materials and supplies you’ll need to lay loft boards include loft boards, screws, tape measure and pencil, drill, hammer, saw, protective gear such as gloves and dust mask.

• Work Out The Area

Measure up the area you need the boards to cover. The standard loft features two different sizes (both are 18mm thick) which include 2400mm x 600mm and 1220mm x 320mm. You should ensure that the board you opt for fits through the loft hatch perfectly.

• Start Laying

Once you’re done working out the area, the next step is to put on your protective gear and start putting the boards in place. You should lay the boards in a staggered pattern so as to give a better strength. While doing this, watch out for any wire running through your loft so they don’t get trapped, you should also cut the boards for easy access to the light fittings’ top.

• Make It Permanent

Upon the successful placement of the boards in a way that offer a safe area to store things and stand on, you’ll have to screw them in place. Start by drilling 2 or 5 holes along the edge of individual boards in such a way that lines up with the centre of the joist below. Once done, then you can fix them in place with screws.

What time can builders start work?

The periods at which noisy work is permitted do vary across the nation because the Control of Pollution Act 1974 provided Local Authorities with the authority to regulate noise from construction sites and similar areas. At the same time as these do differ across unalike councils, the average hours throughout which noisy work is tolerable is usually between 8 am and 6 pm from Monday to Friday. This is usually based on the impression of ‘noisy work’ being carried out, so labours could start earlier to prepare things for the day but then not start carrying out their work until 8 am.

On Saturday’s builders are usually allowed to work between 8 am and 1 pm, but this can differ to some extent with different councils. It does mean that workers can start at the identical time as the rest of the week, but they are generally required to finish a lot prior. On Sundays and Bank Holidays there is not as much of detailed direction on hours, but most councils say that there should be no noisy work taking place. Although these are decent strategies, it is worth examining your Local Authority website as they can change slightly. Noisy work is commonly described as ‘noise audible at the site boundary’ and it may be the case that workers are there outside these hours but are setting up before carrying out noisy work.

Local Authorities also recognise that now and then it is unescapable to work separately to these hours, such as work on railway tracks that must be done when trains are not running. Though, local councils do have the authority to serve an announcement on individuals carrying out building or demolition works and tell them how the work should be carried out to evade a possible lawful noise irritation.

How to plasterboard a brick wall?

How To Plasterboard A Brick Wall

Do you want to cover your brick wall with plasterboard? The key to success here is the preparation. You must ensure that brick wall is prepared well enough to receive the plasterboard. To get started, there’s the need to attach wood furring strips to the wall which serves as studs in a wood frame structure. This way, the plasterboard will be prevented from getting in touch with the brick. You can always hang pictures or any other forms of decoration in between the gap between the walls. Let’s have a look!

lAttach Furring Strips

• Get a 2 inch by 4 inch wood stud and apply a bead of construction adhesive.

• Using a masonry bit, drill a pilot hole through the wood stud’s base as well as the brick wall.

• Hit a 3 inch fluted nail through the hole using a sledgehammer

• Using a construction adhesive, bind a horizontal 2 inch by 3 inch stud to the upper edge of the wall.

• Using an adhesive, bind the length of a 2 inch by 3 inch stud on its wide side.

• Use a masonry drill to drill a hole on the wood stud and 1 1/2 inches into the brick wall.

• Hit a 3 inch fluted nail through the pilot hole.

lApply Plasterboard

• Hold a plasterboard sheet against the furring strips.

• Use plasterboard screw to hold the drywall sheets in place.

• Use fibreglass to cover the joints where the two plasterboard sheets meet.

• Use a thin layer of the joint compound on the tape. Once done, screw it using a 6 inch taping knife, then allow to dry overnight.

• Use a sandpaper to smooth the joint compound.

• Use a fresh coat of the joint compound to block the holes and joints. Once done, allow the compound to dry.

• Use a light sandpaper to smooth the final coat.

Plasterboarding a brick wall is a simple task but the preparation part must be done right to protect your investment. Therefore, we’d recommend you hire the services of a skilful professional, who can guarantee the best results especially if you lack enough training and experience to carry out a DIY project.

how to underpin a house

The importance of underpinning a house cannot be overemphasized. Firstly, what is underpinning? Well, underpinning is simply the act of reinforcing, repairing, strengthening or improving the depth of an existing foundation by lowering the footing to ensure that it rests more on more reliable and supportive soil. Not only does this method help to strengthen your building and preserve its structural integrity, but it also does increase your property’s value and gives you peace of mind knowing your property is safe. If you’re thinking about underpinning your house, you have two options – do it yourself or call in a reputable structural engineer. The latter is more advisable as the method involves a lot of specialized knowledge, skills and tools to guarantee a successful outcome. In this post, we’re going to take you through the process involved in underpinning a house. Let’s take a look!

To get started, you should know that concrete underpinning features excavating pier footings around the building at about 2 to 3 metres distance between each other. In some cases, underpins can be installed from within the house. The footings of the underpin should go very deep into the underlying soil in such a way that fully supports the weight of the building or structure. Once done, now proceed to attaching the new footing to the building. You can achieve this by excavating underneath the existing footing to make for a stronger prop. Individual prop and pier arrangement is then strengthened using strong steel bars. Once completed, the concrete is then poured.

A professional underpinning contractor will make sure there’s sufficient space left between the existing footings and the new underpins as this space will ensure that the new underpins can be easily used to jack up the house and level it once the poured concrete cures.

how to repair concrete driveway pitting?

Pitting, also referred to as spalling is the event whereby “pits” or small holes start showing on the surface of your concrete driveway which makes it appear both worn and uneven. Concrete driveway pitting is a common but highly frustrating problem for most homeowners. You’ll see some concrete driveways that’ll only start to pit after a couple of years, but this is not true for all concrete driveways as others will start to show signs only after a couple of months. So how do you tackle this issue? Well, it’s relatively simple to tackle, however if you’re not confident or lack the necessary skills, we’d recommend you get in touch with a reliable professional who can guarantee the best results for help. In this guide, we’ll take you through the concrete driveway pitting repair process.

✓ Prepare the pits by cleaning the area, clearing out all debris and more. The small pits can be cleaned with a stiff brush while a sturdy broom will do a good job for larger pits.

✓ Make use of a hose to spray the concrete pits and flush out all remaining bits of waste.

✓ If you’re tackling series of small pits, simply use a caulking gun filled with pre-mixed epoxy and specially formulated for concrete to fill the pits. Clear off the excess eproxy ensuring that its level with the concrete surface. Once done, simply leave for at least 24 hours before the application of a concrete sealant to prevent the wear and tear of the new concrete.

✓ Chisel out a little concrete and clean with a pressure washer. Once done, apply a concrete resurfacing compound mixture into the holes and use a trowel to level off.

✓ Ensure that the repaired concrete driveway is protected from rain and foot traffic for at least 6 hours (or 24 hours for vehicles).
