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

what is the best loft insulation?

If you have a loft, then the next thing that’s crucial is a loft insulation. Asides from cutting down on your carbon footprint, when you’re able to install an effective loft insulation you can slash your heating bills by up to £250 per year. What’s more? Besides making your home more energy efficient, it can also increase the value of your property a great deal. So if you’re also considering the insulation of your loft, one of the few things that comes to mind is, what loft insulation is the best to incorporate? In order to help you make the best informed decision possible, this post is going to address this issue and put you on the right path.

 

In truth, there’s no way to say exactly which type of insulation is the best as all types usually have a different purpose as well as usage. The insulation you choose for your home’s loft is be based largely on the how you’re going to make use of the space as well as any unique challenges you might face given the shape of your home’s loft. Below are some types of insulation to give you a better idea:

  • Blanket insulation. This is the most common type that comes in rolls of rock, glass or mineral fibre ( or foil-backed felt ). It normally the most affordable and also a good all-purpose insulation which is easy to fit although not suitable for the roof.
  • Loose-fill insulation. This type of insulation features a loose, lightweight material such as cork granules, cellulose fibre, mineral wool etc. It can either be incorporated as a top up or on its own. The primary drawback is it isn’t very secure and can also be very messy.
  • Sheet insulation. This is the best solution for the roof’s underside as it offers a highly effective insulation for your loft space and can also be decorated over. The drawback here is that it’s usually the most expensive type to purchase and install.
How long does it take to install insulation?

How long it takes to install insulation will depend on the size of your property. In general, loft and cavity wall insulation can be installed in a day or two. External wall insulation will usually take longer to install. The rep or installer will be able to advise you when quoting for the job how long this will be.

do i need planning permission for a garage conversion?

Are you thinking about converting your garage into a new space? Be it a new bedroom, gym, library or playroom, one thing you’ll have to consider before getting started is whether or not you’re going to require a planning permission. Unlike extensions that needs additional space, garage conversion is all about changing the existing structure of a space that’s already available to you - your garage. As a result, these projects are mostly covered by a planning policy that’s a bit different.

For a garage conversion, it’s very unlikely that you’ll need a planning permission. As a matter of fact, only 10 percent of garage conversions has been estimated to need a full planning permission, with the others coming under the permitted development rights. The permitted development rights, however, only provides coverage for home improvements that’s internal which implies that so far you’re not trying to enlarge your garage, you’ll not require a planning permission. But if otherwise, you’ll have to submit an application before commencing your project.

If you’re looking to comply with the permitted development rights, then your project must comply with some specific guidelines. These rules include the following:

• The work should be internal. No plans to enlarge or extend the existing garage.

• You should make sure that the materials used in carrying out the garage conversion is the same with the materials used in building the existing house.

• The building should not be extended.

You may, however, require a planning permission if you’re going to change a detached garage into a living space which could be a bedroom, small annexe or a living room.

Some houses excluded from the permitted development rights include flats, listed buildings, some new developments and most homes in a conservation area.

how thick should render be on external wall?

Render serves two basic functions. One is it’s protective qualities as render acts as waterproof for the wall which enables them breathe by allowing water vapour move from the inside to the outside of the structure while also working to prevent water or rain from finding its way inside the structure. While the second function is the decorative qualities as render is able to provide the structure with a fine finish and colour to make the building a lot more appealing and correcting faults in line and level in the masonry.

If you wish to apply render on your external wall, you’d probably be wondering just how thick the render should be to perfectly serve both of functions. In this article, we’re going to take a look at just that!

For a render thickness, the British Standard Wind Driven Rain Index has come up with 4 ratings which include Sheltered, Moderate, Severe as well as Very Severe. An area with Very Severe rating include South West England. This rating implies that the thickness of the render in this area should be increased to at least 20mm for a direct one coat render applications as well as 5 to 6 external wall insulation base coat applications. And if you happen to reside within one mile of the coast, it’s strongly recommended you incorporate an extra repellent protection like Paraguard AG from Parex.

In general, render that’s prepared on site with cement and sand should be have a minimum of 20mm to 25mm thickness. Although, it should be noted that the quality of the render is based on quality of the sand incorporated, the design mix as well as being largely dependent on how good the mixing technique from the applicator is. The most common reasons why traditional renders fails is due to both poor mixing ratios and low quality materials used.

how to convert your loft into a room?

How To Convert Your Loft Into A Room

The loft is the space on top of a home that’s most often ignored by home owners due to having to consider the space’s configuration, the lighting as well as energy efficiency. However, when successfully converted into a room, it can serve several purposes which would even add more value to your property. So how can you convert your loft into a room? Let’s have a look.

• Take Into Account The Size Of Your Loft

The size of your loft is a major determinant of the type of room it can be converted into. A small-sized loft there’s a chance it can still be converted into an extra bathroom or home office while bigger lofts can be converted into an additional bedroom. The minimum head height is 2.3m, if your loft is lower than this, you’d have to get a planning permission to detach some parts of the room for extension.

• Include A Skylight

When a loft is poorly designed, the room become dark, shady and airless. Adding a skylight to your loft will let in fresh air, deliver better ventilation and more light.

• Insulate Your Loft

Loft insulation will not only prevent heat from escaping through the roof, but also lead to an improved energy efficiency which ultimately helps you save up on your heating bills.

• Use Modern Colourization

When you use bright, neutral and modern colours to paint your loft, you’re adding that elegant look to the space. As a result, the loft looks a lot more attractive and comfortable by the time you’re done with the conversion.

The conversion of your loft into a room can be a very tedious task if you wish to do it by yourself. We’d recommend you employ a seasoned professional for help in order to ensure the best results and also to avoid making costly mistakes.

How to cut plasterboard?

Cutting a plasterboard is a relatively simple process requiring only some basic tools. Unfortunately, the lack of knowledge serves as big deterrent for many people who wishes to put it to good use. Plasterboard can actually be sawn using an ordinary timber saw that’s fine-toothed to get a cleaner edge. However, the basic tools you may also need includes a sharp knife (Stanley Knife), pencil, a fine sandpaper, a straight edge and measurement tape as well as a wall board saw. Let’s have a look at the cutting process!

• Firstly, you need to put the plasterboard sheet flat on a firm surface.

• Use the tape measurement to measure the cut you wish to make.

• With the help of a pencil, simply mark out the part you wish to cut on the plasterboard’s front side.

• Once marked, place a spirited level over the marked spot on the plasterboard sheet you want to cut.

• Cut a shallow mark into the plasterboard sheet using the Stanley Knife to cut along the edge.

• The cut should be slow and gradual to ensure you do not wander off the edge of the marked area.

• Once the shallow cut has been made, turn the plasterboard sheet on its edge and deliver a quick and sharp push towards the plasterboard’s back and on one side of the cut.

• Place the plasterboard sheet backing against a flat surface ensuring the line of the cut is over an edge. Once done, give a quick and sharp push towards the back of the plasterboard sheet and on the part of the board is reaches beyond the edge.

• Using a fine sandpaper, remove all forms of paper burrs.

The process of cutting plasterboard requires a lot of practice. If you lack the training and experience, the cutting process is best left to a proficient professional who can guarantee the best results the first time and save you some additional costs due to potential damages.

how to refurbish your house?

If you’re thinking about refurbishing your house or property but don’t know how to go about it, then you’ve come to the right place. In truth, not every home refurbishment works goes in exactly the same order, however it’ll do you some good to abide by a specific plan in order to avoid both unnecessary works as well as expenses. For instance, how would it feel if you have already closed walls and paint only to realize that there’s a need to include a new plumbing stack that has to go behind the wall? Not good, right? Well, this guide is designed to help you avoid such frustrating situations. Let’s have a look!

✓ Establish a plan. This involves carrying out a good assessment of what you’d like to refurbish and set the priorities like deciding where to start and making sure you have both the time and budget to complete the project.

✓ Set a budget. Establish a final amount that’ll be the threshold to your spending. It’s always good to add an additional 10% to 15% to cover unexpected costs.

✓ Hire a contractor. Carry out a research, reach out to many contractors, compare their prices, work quality as well as integrity before hiring.

✓ Talk to your insurance company. Find out if you have the amount of coverage that suits your needs from your insurance company before and after your project.

✓ Secure permits and order materials. Make sure you check with the latest regulations before commencement. Once done, you can start ordering the required materials.
