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 to refurbish a house?

Refurbishing a house brings about a plethora of benefits. These includes an increased sale value, an improvement on your quality of life or even simply to make it more visually appealing. All these are great when you look at them, but one thing that happens to be an hindrance for several homeowners is the cost of getting the project done. You may wish to set a budget, plan and prepare before commencement of the project, but the fact remains that, when it comes to refurbishing a house, nothing is certain. In fact, it’s advised to always expect the unexpected and have a lot of cash in reserve just in case something goes wrong. There are a wide range of factors that can play a key role in the overall cost of a house refurbishment. Minor refurbishment that should cost around £30,000 can easily go up to over a whooping £150,000 for a total transformation. Most of this cost will be expended on labour, and the next most significant expense, which is sourcing materials.

In general, the cost of your refurbishment project will depend on some factors which includes the size of the project, the materials used, the refurbishment or renovation level, the location of the property, the quality of the contractor hired and lots more. To estimate the cost of refurbishing your property, you can follow these simple steps:

✓ Write down a detailed list of all the things that needs to be done per room and try to be as specific as possible.

✓ Carry out a research of the labour cost in your area as well as the raw materials’ cost (here, you can make use of guides such as home advisor).

✓ Add an extra 10 to 15 percent on top of the calculated estimate for uprisings and repairs.

✓ Talk to your contractor to get a more accurate quote.

can a mortgage include renovation costs?

It can be very hurtful when you’re looking to get a house and then identifies one that’s almost perfect, but that one thing that’s lacking is significant enough to prevent you from making an offer. For instance, you may like neighbourhood, the lot’s size, the number of bedroom and lots more. However, the only thing that’s holding you from making an offer is the outdated kitchen. This is the point where you wonder whether a mortgage can include the cost of renovation. In this article, we’re going to give you a good insight into this and more. Let’s have a look!

One of the major things your lender will put into consideration when you apply for a mortgage is the price of the property in question. For instance, so you’ve found your “almost perfect home for let’s say £400,000 and the cost of your intended renovation work runs up to about £150,000. In this event, you’re definitely going to find lenders who wouldn’t be too keen to let go of their cash. And that’s mainly due to the fact that lenders are only able to afford you, at best, 95 percent of the purchasing price. In other words, if you really want the house, you’ll have to finance it yourself no matter how much potential you think the house possesses.

This, however, does not mean that you can’t find some mortgage lenders who’ll allow for building costs. They exist, but this will mostly take place when the work is complete and the property is revalued. You may also be lucky enough to get a purchase plus improvements mortgage which allows you to renovate now and pay off the renovations over time at a better interest rate than other loan types.

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.

how much is a single garage conversion?

Converting your garage into a habitable room can be an option that’s too good to pass up especially when you’re in dire need of more living space in your home. If you’re in a similar situation and considering the cost of a single garage conversion in your home, then you’ve come to the right place! The fact is, the cost of a single garage conversion is dependent on a number of influencing factors which includes your specific plans as well as your location. Generally, the price of garage remodel is expected to cost about half of what you’ll incur when building a home extension or addition from scratch. However, before commencing a project of this magnitude you should put into consideration some things.

A single garage conversion is a huge job which typically involves wall insulation, floor raising, heating addition, cool and ventilation as well as updating doors and windows. Before you get started you should consider if converting your single garage into a room is a good option, whether a permit is required to convert a garage, the type of room a garage can become, does it add value to your home and how much its going to cost.

Just like any other home improvement project, garage conversion cost varies depending on several factors like your garage space specifications. Other factors include the general condition of your garage - the condition of your foundation, walls, floors or roofs, the ceiling and more, planning applications, your location, the services of a structural engineer, internal or external garages etc. According to Santander, the average cost of converting a single garage costs approximately £6,300. However, considering the aforementioned influencing factors we’d expect the cost of a single garage conversion to cost within the range of £5,500 to £10,500.

what is a garage conversion?

What is your garage being used for? If your answer is anything besides your vehicle, you’re in the majority in the UK. In the country, according to a research by Admiralty Loans, several home and property owners now use their garage as dumping ground for all sorts of stuffs asides a car. Ultimately, this gives rise to garage conversions as the more or less underutilized space can be converted into a living space which can be more beneficial while also adding more value to the property.

A garage conversion is a fast and relatively affordable route to adding more floor space within your home. It’s basically the act of changing your garage into something other than a storage or a place in which you can park your car. This can be anything from a bedroom to a playroom and anything in between. It’s a great way to provide extra space to allow your family to spread out and have more privacy while still within the walls of your home.

A garage conversion project is a huge one which mostly does not require a planning application so far the conversion is internal. However if you’re planning to increase the garage’s size or change the exterior of your home, or convert your garage into a separate room, then you may require a planning permission before getting started. It’s always wise to consult your local authority before carrying out any work to be on the safer side.

A project of garage conversion’s magnitude is better left to a reliable professional who have the experience when it comes to dealing with building regulations and more. This way, you’d also get to save yourself some headaches and some extra cash which may result from possible costly errors.

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 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 to repair concrete driveway pitting?

Pitting, also referred to as spalling is the event whereby “pits” or small holes start showing on the surface of your concrete driveway which makes it appear both worn and uneven. Concrete driveway pitting is a common but highly frustrating problem for most homeowners. You’ll see some concrete driveways that’ll only start to pit after a couple of years, but this is not true for all concrete driveways as others will start to show signs only after a couple of months. So how do you tackle this issue? Well, it’s relatively simple to tackle, however if you’re not confident or lack the necessary skills, we’d recommend you get in touch with a reliable professional who can guarantee the best results for help. In this guide, we’ll take you through the concrete driveway pitting repair process.

✓ Prepare the pits by cleaning the area, clearing out all debris and more. The small pits can be cleaned with a stiff brush while a sturdy broom will do a good job for larger pits.

✓ Make use of a hose to spray the concrete pits and flush out all remaining bits of waste.

✓ If you’re tackling series of small pits, simply use a caulking gun filled with pre-mixed epoxy and specially formulated for concrete to fill the pits. Clear off the excess eproxy ensuring that its level with the concrete surface. Once done, simply leave for at least 24 hours before the application of a concrete sealant to prevent the wear and tear of the new concrete.

✓ Chisel out a little concrete and clean with a pressure washer. Once done, apply a concrete resurfacing compound mixture into the holes and use a trowel to level off.

✓ Ensure that the repaired concrete driveway is protected from rain and foot traffic for at least 6 hours (or 24 hours for vehicles).
