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 good is external wall insulation?

External Wall Insulation (EWI) is the act of insulating a home by fitting insulation to the exterior parts of the building which in turn improves thermal performance, cuts energy consumption ( savings on energy bill) and also adds to the home’s visual appeal. The systems are built in multiple layers, with the insulation board offering a plethora of options with each being suitable to varying projects and their needs. Installing an external wall insulation comes with a variety of benefits, let’s have a look!

• Thermal Performance Improvement

With EWI, the thermal inertia of the walls are greatly enhanced while also restricting the loss of heat. Ultimately, this lowers heating costs, enhances the comfort of indoor thermal and also reduces CO2 pollution.

• Eliminates Noise Pollution

When the noise levels are high, it can have a bad impact on our overall well being. A great way to reduce the disturbances from the outside like traffic noise is by fitting an External Wall Installation system.

• More Comfortable Living Space

Do you know the damp in homes can contribute to respiratory problems? A properly insulated home will greatly limit the impact of condensation by combating the damp issues. As a result, you can always expect your house to be cosy and comfy irrespective of the season. A cooler summer and warmer spring is guaranteed with EWI.

• Enhances The Property’s Visual Appeal

Looking for an excuse to rejuvenate your home’s aesthetic appeal? Well, you can as well try out adding an EWI system. There are a plethora of unique colours and styles you can pick from to beautify your home effortlessly.

• Adds Value To Property

An insulated home will generally cost more than an uninsulated one at the time of resale. Potential home buyers are more interested in the acquisition of a home with an EWI system due to its various benefits - and a higher demand can only imply a higher price!

Will my garage conversion cause disruption to the rest of the house?

It shouldn’t do. Most companies will do all the interior work first, and the last job to do will be creating the opening from the house to the conversion. A reputable company will make sure they cause as little disruption as possible during this time.

how long does it take to pebble dash a house

Are you looking to pebble dash your house? This is a cool way to add a stunning new look to your home or property while also adding to its resale value should you wish to sell later on. The list of the benefits goes on, however one thing that most home and property owners would like to know before starting such a project is exactly how long it’ll take to complete it. If you’re also having similar thoughts, then you’ve come to the right place! In this post we’re going to give you an insight into the duration of pebble dashing a house. Let’s take a look!

First and foremost, just like any other home improvement project, the duration of a house pebble dashing project is affected by a number of variables. These variables include the size of your house, the company or contractor hired and lots more. In general, a house pebble dashing project should take within the range of 3 to 14 days depending on the size of your home. It should be noted that you’ll have to pay the workers on a daily basis. Most labourers will charge within the range of £140 to about £160 per labourer per day. And you should expect to have at least 2 labourers to work on your house’s pebble dashing project per day. On the other hand, the more labourer you have working on your project, the more you’re going to pay on a daily basis but this will also significantly reduce the time frame it’ll take to get the project over the line.

how much to render a house?

Rendering a house’s external walls is one of the cheapest and most effective ways by which a building can be made waterproof and also good looking. If you’re thinking about rendering your house, figuring out the cost of completion is usually one of the most important things you’ll have to consider before you proceed and if you don’t know where to start, finding an experienced tradesperson who possesses several years of experience as well as the ability to overcome the different issues that he may be faced with while on the project is paramount. If you’re able to get one, however, you should know that they rarely come cheap.

When trying to determine the accurate house rendering cost estimate , a tradesperson will put into consideration a great number of factors. Even at that, a rough estimate still requires both skills and expertise to be able to take into account all the necessary factors. In general, a typical 3 bedroom home in the UK will cost within the range of £4000 to about £5500 for a complete render job on the outside and covering from top to bottom.

Usually, the most important factor which play the biggest role when determining rendering costs is the area that’s going to be covered by the render mix. Professional contractors will provide a quote based on the rendering costs per square metre. Below are some rough estimates of rendering costs of properties depending on their size (without VAT).

✓ For a small mid terrace house of about 40 to 50 square metre, the total rendering cost estimate is £3000 to £4000.

✓ For a large mid terrace house of about 70 to 180 square metre, the total rendering cost estimate is £3000 to £5000.

✓ For a three bedroom detached house of about 100 to 160 square metre, the total rendering cost estimate is £4000 to £5500.

How many bricks can a bricklayer lay in a day?

Well, just like many other team work, a bricklayer is only as good as his supporting cast. And a hard-working labourer should be able to keep three bricklayer gangs happy. But even when he gets to serve just one bricklayer, the site conditions and nature of the wall can also play a huge role in determining the number of bricks that can be laid within 24 hours.

With the best possible site condition, hard-working labourer and best scenario with no pillars, no face brick, long straight wall and no wall ties, a well trained bricklayer should be able to lay within a range of 800 to 1100 bricks all day long. However, you rarely get walls like this as there is always going to be some corner or curve somewhere which usually takes some time to get right. Furthermore, once the bricklayer has laid up to 5 feet, there’ll be a need to get some lift. From that point onwards, the job understandably gets slower and tougher - meaning there’ll most definitely be a face brick.

In addition, there are multiple other factors that can affect the number of bricks that can be laid in a day. Sometimes its the complex designs or weather that’ll determine the daily rate.

With the aforementioned factors and more realistically, on a good day and great site, an expert bricklayer should be able to lay about 500 to 800 bricks in a day. This is generally a very good target, but of course you never can tell with the reasons above and other factors that are simply beyond the control of the bricklayer. If you have a project and want it completed as soon as possible, you can pay the bricklayers based on the number of bricks laid to increase their efficiency.

how to tile a porch roof?

Tiling a porch roof is a very important but laborious and difficult task. A project of this magnitude will require a large investment in planning and preparation way before the actual installation process takes place. It can be a brand new porch roofing tile or a replacement of the existing one, either way it’s crucial to get the right technique. If you lack proper training or experience in this field, we’d recommend you hire the services of a reliable professional probably within your local area to guarantee the best results and to save yourself some time and money. This guide will give you a good insight into the porch roof tiling process. Let’s have a look!

• With the crown looking upwards, put the first tile on the batten and centre the tile from side to side.

• Hammer a 10d nail at the base of the tile and into the batten (make sure not to overdrive the nail).

• To provide a much needed support, apply a little mortar under the first tile.

• Identify the inner end of the first tile and place another tile on top. Take a measurement from the outer end and adjust the end of the second tile to fit.

• Just like you’ve done with the first tile, nail the second tile into the batten.

• Position two tiles at the both ends of the ridge and proceed with the installation just as you’ve done with the previous tiles.

• Take a measurement of the distance across the ridge from the first tile’s outer end. Once done, you can then calculate the number of tiles required by subtracting 16 inches from your measurement and divide the answer by 8.

• Beginning at the second tile on one end of the ridge, install the half the number of ridge tiles towards the centre of the ridge. Now install the remaining tiles working from the opposite end to the ridge’s centre. At the centre of ridge should be a key tile with mortar.

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 much is a loft conversion?

With the ability to add approximately one third of your existing living space ( by converting your old, unused attic) to your home or property without having to let go of your garden, it’s quite easy to see the reason why loft conversion has rapidly grown to become one of the most popular home improvements in the UK. However some homeowners usually shy away from the idea simply by looking at the perceived high cost of carrying out such a project, despite several researches showing that loft conversions offers the best rate of return on initial investment when compared to the other home improvement projects. So exactly how much would it cost to carry out this project?

Just like several other home improvement projects, the cost of a loft conversion varies greatly depending on a wide range of influencing factors. These factors include the size of your home, how old your home is as well as the quality of the fixtures and fittings you want to install. For instance, a high end bathtub alone can cost you thousands of pounds, meanwhile you can also construct a full bathroom suite on just a couple of hundred pounds. However, to give you an idea of the minimum cost of a loft project we’ll look at the most popular types and the minimum cost of each.

✓ Internal Loft Conversion - The most affordable type of loft conversion tends to start from £25,000 and above.

✓ Dormer or L-Shaped Dormer Loft Conversion. These are the most popular types of loft conversion. Dormer price tends to start from £35,000, while the L-shaped dormer starts from £45,000.

✓ Mansard Loft Conversion - This involves replacing the entire side of a sloping roof with a vertical wall and flat roof. It requires a planning permission. The type of loft conversion usually starts from £45,000.

✓ Hip To Gable Loft Conversion - This usually starts from £50,000.
