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

how to repair hole in asphalt driveway?

Is there a hole in your asphalt driveway you feel you can repair yourself? If it’s something you know you can confidently do then this step by step guide is just for you. If otherwise, then we’d recommend you hire the services of a reliable professional who can guarantee the best results while also saving you some time and extra money that could result from possible errors. In this article, we’d go over the reparation process of an asphalt driveway with a hole in it.

✓ Get the necessary tools. You’re going to need a broom ( to clean the area), caulking gun ( to fill the hole), a hand tamp a plate compactor or a hammer ( to level the filled in hole) and a weeding glove (just in case there are weeds growing in the hole).

✓ Prepare the area. Do this by weeding the plants or weeds that might have grown inside the hole and identify your asphalt filler.

✓ Wet your soil, if necessary. It’s important to note that this is only necessary if your soil is dry to help the filler stick properly.

✓ Fill in deep holes. If the hole goes down about 3 to 4 inches or more, simply fill it with any material like rocks, clay etc.

✓ Apply the asphalt filler. Fill the hole with the asphalt filler to about half an inch higher than the surface of the driveway.

✓ Level the filler. For a large hole, make use of a plate compactor or a hand stamp, but a hammer will be sufficient for smaller holes.

✓ Cover the hole, if necessary. If your home isn’t level, covering your hole with a piece of plywood is advisable.

✓ Clean off the seal. After the asphalt looks done and in place, simply brush away the debris from the seal to finish off the project.

Fitted wardrobes are the best choice of wardrobe for most households and they’re a popular option for several homeowners for a good reason. Not only are they able to efficiently maximize your space and fit into any space no matter how awkward, but they can also be customized to fit your personal needs to feature custom lighting and many more.

This is a relatively easy task if you’re attentive to the details, however, if you’re not confident enough to pull this off, we’d advise that you get in touch with a professional who can guarantee the best results for help.

To construct a fitted wardrobe in an alcove, simply follow these steps:

✓ Take a measurement of the available space including the length, breadth and width.

✓ Sketch out what you want the wardrobe to look like while also staying within the measurements. Here, you’ll have to be particular about everything like the drawers, shelves etc.

✓ Build the frames upon which every other construction would be made.

✓ Attach the frames to the wall and floor. Make use of a hammer drill with a masonry bit to drill the holes if its a concrete floor.

how long does a garage conversion take?

Garage conversion is a great way to add extra usable space to your home without having to extend your property. A fun fact is that, in the UK if you have your car parked in the garage, you’re in the minority. According to a research carried out by Admiral Loans, just about 33 percent of home owners in the UK store their cars in the garage. For most people the garage is literally a dumping ground that’s never fully utilized as such. In recent times, the garage is now being used to store a variety of other stuffs asides a car which includes garden furniture, tools and appliances, utilities such as washing machine, fridge and freezer as well as food and groceries. These facts show that more and more people are underutilizing their garage when they may actually be in need of more usable space in their property. So why not put into consideration converting the garage into a new space that would be able to serve more purpose?

If you’ve decided to convert your garage, you’d probably want to know the how long the project will take. There are a wide range of factors that can determine the duration of a garage conversion project. These factors include:

• If the foundation needs reinforcing

• If the floors, walls, or roofs are in a bad condition.

• If the ceiling height needs some raising

• If the insulation required in newer builds.

All aforementioned factors will make the garage conversion project take longer than expected. However, in normal situations garage conversions are relatively quick to complete once you start the building works. A single-car conversion will usually take about 3 to 4 weeks to complete depending on the existing garage’s structure.

how much does a garden room cost?

Adding a garden room to your property is a great way of creating an additional space within your home without having to invest heavily in large house extension projects. And not only does it expand your living space, but it’s also a way to add good value to your home or property. With the various benefits offered by a garden room, most individuals are usually surprised with just how affordable the living space can be. However, just like any other home improvement, the price of a garden room is influenced by a wide range of factors. These factors include the design you opt for whether standard or customized, the size of the garden room, the materials used, the number of fixtures and fittings you want as well as any other special design feature you require.

Asides from the money needed to put up the structure, there are also some common extra cost that’ll also be expended for both the interior and exterior of the living space. For instance, there are some furnitures and fittings that you’d like to put in your garden room and these will also form part of the overall cost. There’s also the electrical connections cost and this will vary depending on the distance of your room, the cables to be used as well as your electrician. For this part, you can expect to spend anything within the range of £850 to £1200 and since it’ll be used all year long, it’ll also require appliances for heating, insulation, electricity and ventilation.

Generally, the overall cost you should be expecting to pay for a modular build garden room will range between £10,000 to £40,000.

How to put up plasterboard?

How To Put Up Plasterboard

Putting up a plasterboard is a vital process when it comes to home renovations. However as daunting as it may seem, with a good guide and regular practice you can master the skill within a small period of time. If you lack proper training and experience, we’d recommend you hire a seasoned professional plasterer for help so as to get the best result and also avoid additional costs due to possible damages.

Putting up plasterboard is way quicker than wet plastering and also significantly reduces the drying time that can slow down your renovation plans. With a plasterboard, you can delve straight into the decorating stage and achieve a smooth finish. Below are the steps required to put up a plasterboard.

• The first step is cutting the plasterboard to shape which be one of the most challenging parts of the process. This is because you’ll need to fit the board around things such as plug sockets and window sills. As a result, this involves cutting complex shapes rather than just a simple straight line. To get this done, simply mark out the cut required with the use of a tape measure, combination square and spirit level for a better precision. Once done, you can then use a plasterboard pad saw to cut along the marked spots.

• After you made the required cuts, the next step is putting up the plasterboard. And depending on where the boards are going to be put, this could be a very challenging task. If you’re going to put the boards on the ceiling or somewhere very high up, you’d probably need an extra pair of hands for help. To get this done, use the appropriate screws to secure the boards in place if you’re installing them directly on studs. However, if you’d be fixing them onto bricks or blocks, a drywall adhesive is your best bet.

how much to board a loft?

How Much To Board A Loft?

If you stay in a building where the space meant for storing stuffs is not sufficient, boarding your loft may be just the perfect solution for you. In several homes, the space is already present, and all you have to do is to make it more usable by boarding it out. This is unarguably one of the easiest and quickest ways to create storage space in your home.

Boarding a loft comes with a number of special benefits which includes:

• Assisting to declutter our living spaces and makes for a more spacious home.

• Creating a usable space whereby all seasonal items can be stored.

• Assisting to reduce heating bills as it prevents the loss of heat. When your loft is well boarded and insulated, it’ll help trap heat and prevent it from escaping via the roof.

• Adding to your home’s value by making your attic a very useful space for storing items.

• Helping to create a quiet space which can used for relaxation or getaway purposes and of course, this will require a bit more structural work.

So now that you’ve learnt a few of the benefits associated with boarding a loft, how much will it cost to have one made? This depends on an array of factors which includes the size of the space needed, the type of materials and labour cost.

Overall, a standard semi detached building will feature a lot of space of about 40 sqm to 50 sqm in size. There’ll be a need to add to the height of the floor joists before installing the chipboard decking boards. This job size should cost within the range of £1,000 to £1,500. It’ll require just a two-person team that are fully equipped and well versed about the processes.
