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 pebble dash a wall?

Pebble dash is an effective way to tune up your house or property as it can go a long way to enhance its curb appeal while also add to its resale value if you should decide to sell later on. Although, it’s highly recommended to leave this task for a reputable specialist, it’s also something that can be done as a DIY task. It must be states that this is a pretty difficult job and even more so if you haven’t attempted it before. In this post we’re going to take you through the processes involved in pebble dashing a wall. Let’s take a look!

  • Mix up water with the lime strictly following the manufacturer’s instructions. Once done, leave it covered up to hydrate for at least 24 hours.
  • Take one part of the slaked lime and mix it up with cement and six parts sand. This is to give the base mixture required to spread onto the surface.
  • Use a trowel to apply the mixture onto the wall. Ensure that the trowel is level and use the edges to make a flat and smooth layer of the mixture on the surface as a base layer. Allow the base layer to dry for up to an hour. Then, rake the surface using a notched trowel and allow to dry for a minimum of 24 hours.
  • Rinse and drain your pebbles. Then, set them under the wall you’re pebble dashing.
  • Take the top coat of five parts sand and mix with one part cement and one part slaked lime. Use a trowel to apply this mixture over the base layer and smoothen it with the trowel to create a flat and even top layer.
  • Spread a plastic sheet beneath the wall you’re pebble dashing to capture any loose pebbles as they fall.
  • Grab the bucket of pebbles below the wall and scoop some of the pebbles up using a scoop or trowel. Some will stick and some will fall into the plastic sheet already placed below. Continue throwing the pebble dash until the surface is completely and evenly covered with pebbles.
  • Lightly press and fit the pebbles on each section into the wall and leave for at least 24 hours to dry.

Will insulation save me money on my energy bills?

This depends on the amount of insulation already present in your property. However, adding insulation has been proven to improve the energy efficiency of your home and decrease your heating bills, this is more obvious in older properties or where single glazing is still in situ.

How to dot and dab plasterboard?

How To Dot And Dab A Plasterboard

If you want a fast and simple way to achieve a smooth and sturdy wall which is decoration-ready, then dot and dab plasterboard is the way to go! It’s a relative simple process but can also be a bit challenging. Therefore, if you lack the necessary training or experience, hiring a professional would be a great step to protect your investment and guarantee the best results. Here, we’ll provide you with a deep insight into the plasterboard’s dot and dab procedures. Let’s have a look!

• At the thickness of the board with the adhesive, mark the ceiling and floor as well as the wall to indicate the centre of each board.

• Ensure the wall’s height is 15mm more than the plasterboard

• Make a mixture of the adhesive and achieve a thick consistency. Apply a consistent layer of the mixture around the wall’s perimeter, edge of the ceiling and any other openings with the use of a trowel.

• Select dabs that are about 250mm long and 50mm to 75mm wide and apply the adhesive in them. Make use of 3 vertical rows for individual boards. Also ensure to apply, at skirting level, a band of adhesive.

• Position the board’s reverse side against the dabs, and laying against the packers. Then make the board align with the ceiling and floor marks with the help of a straight edge.

• Raise the board till its tight against the ceiling with a board lifter. Once done, use the plasterboard to wedge the board into place before you remove the board lifter.

• Repeat the same process for the remaining parts of the room. Once completed, make sure the adhesive is set before you remove the boards.

how much to renovate a house?

When it comes to house renovation costs, nothing is certain. As a rule of thumb, you should always expect the unexpected. Unforeseen circumstances (mostly unfavourable) can crop up from anywhere, at any time, greatly affecting the cost of the project. However, if you’ve completed proper planning and done your due diligence on your property before commencement, there’s absolutely no reason why you can’t put the works on budget.

The cost of a house renovation project depends on a lot of variables. These variables include the type of property you’re undertaking as well as the amount and complexity of the entire project. What’s more? Whether you decide to do some of the work yourself or wish to hire quality tradespeople to cover the entire project will also tell on the cost of the home renovation.

In the event whereby you wish to completely gut your property and begin from square one, here are some of the cost you’re most likely going to incur:

✓ Planning applications and building controls

✓ Architect’s design and specifications

✓ Contractors and build costs

✓ Snags as well as unforeseen problems

What will be the biggest cost, which will be determined by the amount of work you need done, is most likely going to be the structural and building work, which can reach up to tens of thousands of pounds.

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.

Is loft insulation flammable?

When thinking about the right insulation material for your loft, some of the first few things that comes to mind is the various properties of that material as well as how good they fit with your home’s needs.naturally, you’d like to ensure that the insulation will be efficient enough to add to the overall energy efficiency of your home, however there are also other features that may not get as much attention but also happens to be equally important. As the primary function of an insulation is to blanket your house to offer a barrier against heat loss, going for an insulation material that’s also fireproof is crucial as loft insulation can burn. Although most insulation materials are fireproof, a myriad of problems can actually make your insulation burn.

 

For instance, fibreglass insulation is produced using glass combined with plastic polymers and is naturally resistant to fire. However, even at that you’d have to be careful with batts that are supported with foil or paper due to the fact that these materials can burn pretty quickly. Cellulose, on the other hand, is not fireproof and is required to be treated by other flame retardants in order to help reduce combustion. Some of the best insulation materials that are resistant to fire includes the following:

  • Fibre glass. This is made of glass that’s spun into fibres, then combined using plastic polymers. As a result, fiberglass insulation is naturally resistant to fire.
  • Mineral wool. Having a high melting temperature, this insulation material happens to be a great fit for thermal applications due to its superior fire resistant properties. In fact, mineral wool is still naturally non-combustible even if composed of recycled iron and steel by-products, or from actual mineral rock itself.
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).

How to fit external insulation?

With the title of this blog, do not be deceived into thinking the purpose is to encourage you to install an external insulation by yourself. Even as a competent DIYer, it’s not advisable to buy a couple of materials and start slapping it into the wall hoping for the best outcome. External insulation is by no means a DIY job and without the proper training and experience, it can easily turn out disastrous resulting in loss of time, effort and money in such a valuable project. This blog, however, will give you a great insight on how the installation process works and help maximize knowledge ensuring you do not spend more than necessary.

External Insulation Installation

lRender Test

• This is done to ensure the existing render is good enough for insulation support.

• If positive, the insulation can be applied directly onto it.

• If negative, ensure removal of the old render before fitting the insulation.

lPipework Adjustment & Removal

• Remove all pipework prior to insulation fitting

• Install temporary downpipes to ensure water is not wasted and everything continue to function normally during the insulation fitting process.

lWindow Protection

• Protect the window with a protective layer or film.

lStarter Track Fitting

• Determine level you want the insulation to start (height).

• Fit the aluminium start track or carrier tray at the identified level.

lInsulation Boards Fitting

• Apply a layer of adhesive to the board and glue them to the wall in a staggered pattern.

• Cut to fit round all obstructions and windows.

• File off the edge of the board where necessary using a rasp upon successful fitting of the boards

lMechanical Fixing Inclusion

• Hammer around 10 fixings per square metre into the board.

• This is to secure the insulation boards.

lBeading Fitting

• Add corner beads and stop beads to ensure the insulation is secure and to prevent it from making contact with other materials.

lReinforcing Mesh & Render Addition

• Apply two layers of strengthening properties and between the two layers of render, include a fibre glass mesh.

lPrimer Application

• Paint on the primer

lFinal Render Application

• Choose your most preferred texture and colour as this will be the last coating of the installation process.

lPipework Re-installation

• Re-install all detached pipework at the start of the installation process.

How much plasterboard do I need?

How Much Plasterboard Do I Need?

Although many people especially contractors have a tough time estimating the number of drywall or plasterboard needed to complete a project, it’s a rather simple task if all factors are taken into consideration. If you’re able to follow the same procedures taken by professionals to count dry wall sheets, you’ll be in the right direction. Let’s have a look at the procedures to follow!

lTake Square Footage Measurement

• Measure the square footage of the area where the plasterboard will be fitted.

• Multiply the height by the width of each wall or ceiling area.

• Add all quantities to obtain a total square-foot amount.

lCalculate Drywall Sheets

• To calculate the number of drywall or plasterboard sheet is very simple once you’ve gotten the total square footage.

• To get started, simply divide the total square footage of area by 32 (that’s if you are using a 4 by 8 sheets) or you can also make use of 48 to make the division (only if you’re making use of the 4 by 12 sheets).

• The answer you get after the division will give you the full number of plasterboard sheets that’s required to complete the project.

We’d recommend you include an extra 10 to 15 percent of whatever you calculate to take care of the possible odd cuts and wastages. This implies that if your total area is 1600 square feet while incorporating 4 by 8 sheets, simply divide 1600 by 32 which equals 50 sheets, now take 10% of 50 which equals 5, then add back the 5 extra to the 50 sheets earlier calculated to get 55 sheets. If you wish to estimate the cost, simply multiply the number of sheets gotten by the price per sheet. Do not forget to include delivery charges and local taxes.
