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 much sand do I need for bricklaying?

Sand is a very important element in bricklaying as far as a mortar mix is concerned. Generally, the quality of the sand is the major factor determining the quality of a plaster mix or mortar mix. It’s recommended that the sand should have enough ‘fines’ (- 75 micron material) to get a good plastic mix with a water content that’s less than 350 litres/m3. Generally, a mortar mix or plaster mix is made within the range of one bag of cement to 200 to 300 litres of damp sand.

Apart from experience the next best indicator of the quality of sand is a field test. In other words, if you do not have the required training or experience in bricklaying, the best bet to determine the amount of sand for a good quality mix is by carrying out a field test. Let’s have a look!

• Get about 50kg of sand and air dry it.

• Scoop 25kg of the sand, 5 kg of cement as well as litres of water ( with 1 litre and 1.5 litres of the water in different containers).

• Mix the cement and sand to form a smooth, uniform and consistent colour.

• One after the other, mix the the sand - cement mixture in the three quantities of water. Do this until you’re able to achieve a mix that’s workable enough to use as plaster.

With that done, you should take note that if 5 litres of water is sufficient then the quality and quantity of the sand is perfect. If you’d require 6 litres of water to get a mix workable as a plaster, then both the quality and quantity of the sand is average. However, if you’d need 7 litres of water to get a mix workable as a plaster, then the quality of the sand is poor. Any requirement of water above 7 litres implies a very poor quality of sand.

do you need an architect for a garage conversion?
Have you decided to convert that under-utilized space ( garage) in your home to a more habitable space where you can do anything asides general storage or parking a car? If yes, then you’d probably want to know where to start or if you’d require an architect to get started. Well, you’re not alone! This is one of the most frequently asked questions when it comes to garage conversions and reasonably so. Talking about where to get started, when it comes to home improvement projects the first step to take is determining whether or not you’d require a planning permission or if your proposed garage conversion is covered under permitted development rights. Once you’ve been able to conclude on that, the next step is deciding whether you’re going to complete the project yourself, hire the services of tradesmen or employing a builder. And this ultimately brings us to the question of whether you’ll need an architect for a garage conversion. To get started, it’s highly recommended that you employ the services of a professional architect or an architectural technologist to assist in designing your garage conversion. However, most garage conversion projects are straightforward with no complex changes to be made so far you wish to avoid applying for a planning permission and staying within the set guidelines of the permitted development rights. In such events, if you’re properly trained and well experienced in the field, then it may be cost effective to design your garage conversion by yourself. It should, however, be noted that it all depends on your personal preferences and budget. If you’re on tight budget and don’t mind a straightforward design, you can save cost by not hiring an architect.
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.

Is external wall insulation safe?

With the numerous benefits that comes with the installation of an external wall insulation in a building, it’s also important to find out whether it’s also safe before proceeding to fit one in your home. Firstly, to ensure that external wall insulation systems are safe, they must be BBA approved, which means they’ve been subjected to a thorough testing by the British Board of Agrement and therefore, suitable for use in UK homes.

Given the fact that cladding materials have recently generated a lot of debate and negative press about how reliable some particular materials are, questions are being asked of the safety and reliability of external wall insulation. However we must clarify that, although external wall insulation can be classified under cladding, it is very different to rainscreen cladding - which caused the Grenfell fire tragedy.

External wall insulation is completely safe. However, when it comes to fire, the safety of your system depends largely on the insulation type in question. The safest type of insulation you can have installed is the Rockwool insulation boards which are rated as Euroclass A1 non-combustible. The board is specially designed in such a way that it contains fire - preventing it from reaching the other areas of the building. They also do not produce harmful emission or smoke when impacted by fire.

Meanwhile, the Wood Fibre, is also a great insulation which is known to char and not burn. Contrary to many beliefs, it actually burns slowly creating this charring effect which produces an oxygen barrier that helps reduce the spread of fire.

To make your system safer, you can also make use of Fibreglass Mesh for reinforcement. It helps to improve the strength of the tensile which promotes the security of the boards attached to the wall.

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).

Are barn conversions a good investment?

A barn conversion can be a great investment for lots of reasons. When done well, barn conversions can be great at holding their value, meaning you could sell yours for a great price. They can also look fantastic, often with period features coupled with large areas of glazing. This can make them a great place to live, especially if you enjoy being in the countryside.

However, barn conversions do have their disadvantages. They may require extensive renovation work to bring their energy efficiency levels up to standard, which can be very expensive. It’s also important to be aware of their location – they might be on a working farm or close to several other converted buildings.

It’s essential to get a survey conducted before you buy a barn you plan to convert. This can tell you about any structural problems it might have and give you an indication of whether you might be able to get permission to convert it. You can also buy barns with planning permission already in place.

how to insulate a loft?

Do you know about 25 percent of heat that escapes from an uninsulated house are lost through the roof? Fortunately, roof insulation is something that can done by all DIYers irrespective of their experience levels. However, if you happen to lack the confidence necessary to pull off this, then it’s strongly recommended that you hire the services of a professional who can guarantee the best results and also save you time and money that could arise from potential cost mistakes. Let’s take a look!

  • Clear out all clutter. This involves taking out all the rubbish and clutter from the loft. In order to work effectively, you’ll need a totally clear and empty loft space.
  • Ensure that there’s sufficient insulation. The importance of a good ventilation cannot be overstated. Poor ventilation will result in forming of condensation and this condensation can make the roof timbers rot and compromise the structural integrity of the entire roof. If there are no roof windows which is the easiest way to provide a loft ventilation, the next best option would be to follow the loft floor along to the point where the roof comes down to meet it. There should be a gap at this point, also referred to as the eaves, between the outside wall and the underside of the roof.
  • Measure your loft area. Take a measurement of the loft space in order to calculate the amount of insulation as well as the type you need. If you’re not sure, always get more that it’s required as skimming on the amount you use will only back fire in form of increased energy costs
  • Check for water pipes.

 

To get started, simply make sure all cracks and gaps in the ceiling are filled using a standard filler or decorator caulk. Once done, clean the gaps in the joists and even to the point of hovering all the dust up. Finally,check for the hazards that can cause you problems before laying the loft insulation.

what is a porch?

A porch is a small and low structure (with a roof) located at the main entrance of a building or house. It’s typically without a window (although newer variations may come with one) and can either be screened-in or enclosed to prevent unwanted access from insects and extremes in weather. In addition, some homes may have a three-season porch or sun porch. This may be situated by the side of the house and covered by the roof overhang - they’re usually screened in to offer good access all year round.

Generally, porches serve a wide range of purposes. They include:

• Provision of an outdoor living space to relax during the summer months

• It’s an informal extension of the the living room.

• It serves as a great place for social gatherings especially in small towns.

• You can take off your dirty shoes and dry a dripping wet dog before entering into your living room.

• It can be incorporated for relaxation purposes and watching street activities.

• It can serve as a reception area for guests.

• It can also be used for outdoor storage.

Pros & Cons Of A Porch

Pros

• Due to the fact that they’re covered, porches may require little maintenance practices.

• It can go a long way to improves the curb appeal of your property.

• It protects against the extremes of the weather.

• It can be constructed using a wide range of materials.

Cons

• It does not improve the use of the property

• It can be quite expensive to install depending of the material required as well as size of the porch.

• It does not add to the value of the home unlike several other home improvement projects

• It may not be safe to be used by a child or pet.
