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 do I know if I have cavity wall insulation?

With cavity walls being very similar to other type of brick works, it can be quite confusing to figure out the type of wall your property possesses. If your house was constructed after the 1920s, then its highly likely the you have cavity walls, while older houses (houses before the 1920s) are likely to have solid walls. What’s more? If you happen to own a home that was built in the last decade, then it’s very possible that it was built with insulation installed during construction.

An effective way to determine whether or not your property is built with cavity wall is to examine the brickwork on your home’s exterior. The bricks will typically possess a regular pattern if it features cavity walls. In the event whereby the brick work is covered by render, you can also figure it out by taking a measurement of the wall’s width. If the brick wall is beyond 3000mm in thickness ( from the exterior wall to the interior wall), then it probably features a cavity. Meanwhile, a wall that’s narrower is very likely to be solid. Stone walls, on the other hand, may actually be thicker but are most times solid.

In a situation whereby your house is built using steel frame or timber frame, or made using pre-fabricated concrete, there are varying rules that applies when it comes to insulation and should be examined by an expert before any insulation is installed. More often than not, most contractors will have installed special air vents, which can also be a good indicator that a cavity wall insulation has been done.

How to renovate a house?

As with every home development project, a home makeover comes with heaps of preparation and, hard work, but it is a remarkable way to breathe new life into an old home.

RESEARCH PERIOD FEATURES AND SAFEGUARD THEM

Get to know your household better, the time it was constructed in, and the kind of individuals who would have lived there. The greatest tactic is to repair current structures, make the house dry and safe.

CHECK FOR RENOVATION RESTRICTIONS BEFORE YOU START

There are certain restrictions that don’t allow you to remodel your house after a certain extent, it should be made clear to you when you purchase the property but if you are unsure about the regulations you should check them up, as it is a criminal offence to carry out unauthorised work to a listed home. Restrictions in Conservation Areas generally affect only the exterior of the property as the intention is to ‘preserve or enhance the character or appearance’ of an area, but the right to develop your house will be affected. This means the kind of work that you could have easily completed in a different location may need certain planning and even permissions to complete in your area.

CREATE A DESIGN FOR YOUR HOUSE RENOVATION

It is very important that you take your time to perfect the design. This will help to ensure that the finished work is in tune with your needs. You will also need to figure it out how the changes might play with the original building.

FIND THE BEST CONTRACTORS FOR YOUR RENOVATION

If you are planning on managing the renovation project yourself, it is advisable to ask from friends or family who have renovated their house before and have undergone a similar experience. They can help you find the right architect and builder. Or else, you can always opt for a project manager.

Can I extend my barn conversion?

Generally, it’s possible to extend a barn conversion, but there are certain conditions that you’ll probably need to meet. Ultimately, it’s up to your local planning office to decide whether to approve your planned barn conversion extension or not.

Typically, small extensions on the side of a barn conversion are often approved, particularly if they serve to preserve the original character of the barn. This could be because the extension will mimic the appearance of the original structure, or house facilities that would look odd in the original building.

However, you probably won’t be allowed to build a larger extension, or one that isn’t in keeping with the appearance of the original barn.

how much does it cost to renovate a house?

Do you want to inject a new lease of life into your home or property, or transform it into a more modern style that better suits your taste? Or perhaps you’re only looking to add more value to your property to enable you sell for a profit in the nearest future. Regardless of your purpose, determining the cost of your home renovation can be incredibly difficult. However, you can still obtain a reasonable budget for the project with proper planning as well as preparation. It’s almost impossible to get an exact figure for any home renovation cost, however, this article aims to give you a good idea of cost range to enable you make informed decisions.

The cost of renovating a house can vary significantly depending on a wide range of factors. Some costs are fixed while others may vary greatly. As a result, if you want to have a more exact figure, you’ll have to call in a professional beforehand to give you an idea of how much they’ll charge. Below are some of the most significant costs you’ll most likely face during property renovation.

✓ Administrative cost. Asides from material and labour, the administrative costs is another important cost you’ll need to factor in. The first thing here is usually insurance, this is because all regular building insurance policies does not cover large scale renovation projects. So if what you’re planning is a huge structural change to your property, then it’s more likely that it won’t be covered by your buildings insurance policy. In this event, you’ll have to take out a specialist renovation insurance.

✓ Planning permission and property renovation. This is another potential cost you’ll have to factor in. Submitting a planning application in the UK usually ranges between £200 to £250.

✓ Adding an extension. Generally, a 4m by 5m extension would cost within the range of £30,000 to £40,000.

Do bricklayers work in the winter?

Yes, bricklayers can work during the cold months, but it all depends on the type of work involved. For instance, residential housing maintenance works such as tuck pointing deficient mortar joints on exterior walls and columns as well as rebuilding of chimneys are best tackled during summer or simply put, the warmer months of the year. This is is mainly because the best results for these activities are achieved in the warmer months and several bricklayers will agree to this fact.

Mixing of mortar using anti-freeze technique to counter-act the effects of a cold weather can lead to white marks trailing down the brick when warmer temperatures comes knocking. As a result, even mortar mixing should be done at temperatures exceeding zero degree farenheit which will hold no serious consequences if the temperature should change to a little bit below the norms. During the winter, a good technique that can be incorporated to when mixing mortar would be to mix them in smaller quantities in a warmer environment. These small quantities will immediately be fed by the labourers to the bricklayers and in such circumstances, the mixed mortars will not be subjected to a freezing temperature for too long.

Generally, it would be very unwise to consider any bricklaying work to be done whenever the temperature jumps to a certain level which would be considered to be very inconvenient to work in. Interior works like remodelling of fireplaces can be tackled so long there is a warm space to mix the mortars while also keeping the materials at an indoor temperature. Bricklaying works that have, however, been completed during the colder months should be subjected to a very close inspection as well as looking for potential damage that can be caused to existing works as a result of the harsh weather.

how to refurbish a house on a budget?

In the event whereby you’ve got big refurbishment ideas for your house but a small budget, then you know it’s time to be a bit more creative and apply some cheap and simple tricks. The best possible way to go about this is to invest time in acquiring new skills rather than trying to save up more money to pay a pro to deliver the results you want. After all, the most significant cost when it comes to house refurbishments is usually the labour cost.

The key to making cheap tricks a lot effective in the refurbishment process is by undertaking small tasks that’ll make a huge impact. A great way to start would be by taking it one task at a time rather than rushing to complete all at once. This way, you’ll have enough time to perfect your skills before moving on to the next.

✓ Paint the interior walls. Although this is a simple task but it’ll save you a lot of money if done as a DIY project. To get started, you’d have to text colour options by painting samplex on the wall first. Once done, you can go for the one that adds warmth, dynamism as well as energy to the room.

✓ Fix up your furniture. This involves re-upholstering and refinishing any piece of furniture that appears tired or overly worn (you can leave out the ones that you do not really like or unnecessary items).

✓ Spruce up small but important items used on a daily basis. This includes spray-painting inexpensive picture frames, recovering lampshades with a vibrant paper or patterned fabric, adding throw pillows to armchairs and couches and the likes.

✓ Fix all small things that are broken. This includes activities like patching the nail holes in the wall, repairing the latch on the kitchen cabinet, fixing the gutter, putting a new handle on the door and lots more.

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.

how big can my house extension be?

The holy grail of home extensions is basically the need for additional space for living as well as leisure. However, before commencing your home extension project, you’d probably want to know just how big your new building can be. In this article, you’ll find the answer to this question which is also frequently asked by many other home or property owners in the UK.

Besides your budget, there are two other major influencing factors that can determine just how much extra room that can be added. These factors include whether you wish to carry out the extension project under Permitted Development rights which is usually for a smaller project or you’d prefer to opt for a larger project which is covered by Planning Permission.

Apart from the limitations in the size of an extension under Permitted Development, the extensions are also a lot more affordable and consumes less time when compared to the extensions under planning permission. So what exactly is the size limit for an extension under Permitted Development and the ones under Planning Permission?

For a single storey extension, the maximum size that can be constructed without having to submit an application for Planning Permission includes:

• An extension should have a maximum length of 6m, if you reside in a terraced home or a semi-detached property.

• Extensions for detached properties can have a maximum length of 8m.

• The extension built must not go beyond half your garden’s area.

• The extension should have a maximum height of 4 metres, but in the event whereby the extension is situated within 2 metres of the boundary of your property, it should not exceed a height of 3 metres.

• The extension should not be higher than the highest part of the existing house’s roof.
