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 can I find a builder in my area?

Finding a builder nearby can have enormous assistance when it comes to your build. Period on site, their familiarity of local planning permission, constructors’ dealers and other local trades are all vital bits of knowledge that you’ll welcome on site.

It is always wise to walk around in your local area or drive to a site where any construction work is going on. It’ll give you a proper impression of the constructors who are active nearby. You don’t have to like their style of work or the project they are currently carrying out – after all, a builder can only produce what’s on the plans in front of them.

Find a Builder Other Tradesmen Recommend

If you’ve had to call an electrician before or a local plumber and liked their work, you can always ask them if they have any builders whom they would recommend. Maximum tradesmen get used to seeing the similar acquainted names from one place to another in the sites they are working on and every so often has favourites for who they like to work with — and who they see as a good source of work.

Always Talk to Previous Customers

Once you’ve found a builder you would like to work with, ask them for a list of previous customers they have worked with; they ought to be glad to offer particulars if they’re self-assured they’ve done an effective job.

Look for a builder online

A decent place to start looking for builders online is on sites like the Federation of Master Builders. They have a search tool where you can find precise crafts in your area and look at their situations. All FMB members are assessed and individualistically examined and are checked to ensure that they have the correct insurances in place.

Can cladding help with a damp problem?

External cladding will have an impact on a damp problem. However, it’s important that cladding is the last part of a damp treatment, as installing cladding over a damp wall will make the problem worse. Do not cut corners or try to remedy a problem with the cheapest solution, a damp proof course may need to be put in place before cladding.

Can I extend the front of my house?

When it comes to extending a home, the rear of the house often comes to mind a lot more than the front. However, this doesn’t mean that you can’t extend the front of your house. This can be done either as part of a renovation project whereby the entire house is incorporated or it can also be done in isolation. It’s possible to extend the front of your house without the need to apply for a planning permission, however, there are a bunch of limitations you’d have to comply with if you wish to carry out with such a project. Sometimes, this may imply that extending to the front of your home is more tedious and tasking than extending your home’s rear. So exactly how far can you extend the front of your home without planning permission?

 

The short and simple answer to this question is 2 metres square area with a height not more than 3 metres. Generally, you do not need a planning permission to build a front porch as long as its area doesn’t go beyond 2 square metres from a public road or walkway. Also, a tiled or slated roof can be as much as 4 metres but other roofs must not go beyond 3 metres in height. If you want to extend the front of your home beyond the restrictions specified, then you’ll have to apply for a planning permission.

 

Extending the front of home can be quite costly, but this can be controlled by not building to the extension to the highest specification, not including an extension on kitchens or bathrooms and more.

do i need planning permission to render my house?

If you’re considering rendering your house or property, then you’d most likely want to know whether or not applying for a planning permission will be needed. In several cases, planning permission will not be required for the maintenance, repair as well as replacement of the existing render on your building. These activities are covered by what’s called “Permitted Development Rights, which allows you to carry out some activities without having to apply for a planning permission but always subject to following some strict guidelines. For rendering, as long as the material (render) possesses an identical appearance to those existing on the house as well as same colour, then you will not require a planning permission. However, there are a number of projects that have been highlighted in which a planning permission would be required. These includes the following:

✓ Re-rendering in a colour that different from the original one used on the house or building.

✓ Rendering over brickwork which was not originally covered.

✓ Rendering over pebbledash

✓ Removing pebbledash and replacing it with render.

Another exception to the Permitted Development rights are for houses in conservation areas, national parks or areas of outstanding national beauty.

Although, you wouldn’t normally require to submit a planning application for approval before you apply render, but in truth it’s actually a bit of a grey area which isn’t totally clear and doesn’t allow for much freedom or creativity. And due to this fact, homeowners who wants an absolute peace of mind may opt to apply for planning permission just in case. It’s also worth noting that whether or not a planning permission is required, a huge rendering work will need to comply with building regulations which includes the need to insulate walls on the inside or outside as part of the work on several older properties .

How long does a small extension take?

If you’re planning to build a small extension on your property, you’ll most likely want to know the length of time it’ll take to complete the home extension. Just like many other home improvement projects, it’s impossible to provide a specific number of day in which your project will be completed as the duration is based on a number of influencing factors. This includes the size of the development work as well as whether or not you plan to live in the house when the work is being done. In this article, we’re going to give you a breakdown of the processes that’s involved in building a small single storey extension alongside the duration for each so you can have an idea of how long your small extension project will take. Let’s take a look!

✓ A small single storey extension will normally take about 3 months to be completed.

✓ Site preparation is the first step in the process and it’ll take up to 2 weeks the dig out the footings and prepare foundations. Followed by a further 2 weeks to fit the damp course as well as any drains required around the extension.

✓ The 5th week is spent on working on the external walls and putting in place blockwork to deliver cavity wall insulation.

✓ The next 2 weeks will be spent on installing the roof structure as well as internal walls.

✓ Once done. The builders will make the structure weather proof and electricians or gas fitters will be on site to add power to the extension. This will be followed by internal walls’ plastering as well as breaking into your main house.

✓ After this, when the plaster is dry and decoration completed, units or furniture will then be installed.

how much does a single storey house extension cost?

If you’re planning to build a single story house extension, this is one of the first questions that usually comes to mind to help you set a budget and start to make plans. But as simple as it seems, a single accurate answer can not be provided due to the fact that there are several variables that can play a key role in influencing the price of a single story house extension. These variables includes the size, location, design or specification as well as the build route. In this guide, we’ll provide you with a rough estimate that you can work with to put you on the right path.

The main determinant of the cost of a single storey extension is the size of the build, while the next most relevant factor is the quality of the finish you opt for. For a small extension, you can expect to spend a sum within the range of £14,000 to £17,000. Meanwhile for a larger single storey extension, if you opt for a large wrap around the extension with a great amount of glass to be incorporated in both the walls and roof, you can expect to pay a sum within the range of £80,000 to £120,000.

Overall, the average cost of a single story house extension is usually within the range of £34,000 to £37,000. For this price, you should get a standard sized rear or side extension which also includes the cost of a kitchen - it’s the most commonly use for a single story extension especially in the UK.

There are some additional costs you may also need to factor in to your extension budget. These includes surveys, architect fees, planning application fee (if needed), insurance and Party Wall Agreement (if needed).

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 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.
