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 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.

Are there different styles of cladding?

Cladding comes in a range of styles, such as flush, shiplap, and featheredge. Many types of cladding are also available in a variety of colours to suit any property. A cladding specialist will be able to discuss what solution is best for your property and how it works.

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 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.

does loft insulation cause condensation?

The short and simple answer to this question is yes, loft insulation does cause condensation. Over the years, problems with condensation in loft spaces have become increasingly common. While this may not be harmful in anyway, when the condensation becomes excessive it can lead to more serious issues taking root in your loft like wet rot, dry rot as well as black spot mould. Generally, the best thing to do if you’re concerned about the condensation in your loft space and that it may rapidly become a bigger problem is to get in touch with a damp specialist as soon as possible.

 

Even though insulating your loft space comes with a wide array of benefits like making the top floor rooms warmer, it’s however comes at the cost of making your loft or room space cooler. Condensation in lofts take place primarily due to the humid air making its way through insulation or other gaps into the loft space and touching a cooler surface which in turn results in beads of moisture on the timbers, lintels as well as the underside of the roof. This is why its always a great idea make use of thermal insulation with a vapour barrier that’s installed on the warmer side of the insulating material.

 

Condensation in loft is caused by excess moisture in the air and lack of adequate air ventilation. Here are some top reasons that gives rise to this in the loft:

  • Extra insulation has been installed in the loft leading to a restriction on the natural air circulation in the property.
  • When the storage boxes or other items that has been stockpiled in the loft blocks the roof vents.
  • The release of steam and moist air into the loft space by hot water tanks.
How to get free external wall insulation?

This is a very great opportunity to not only get free external wall insulation, but also cut down your energy bills depending on the type of property you live in. Generally, to enjoy free external wall insulation you must at least be part of the group receiving one of the benefits listed below and also depends on the amount of money you earn. The benefits include:

• Income based jobseeker’s allowance (JSA)

• Income support

• Income-related employment and support allowance (ESA)

• Tax credits

• Pension credit guarantee credit.

• Universal credit.

There are also other important factors that determines if you can have a free insulation fitted on your property. These includes the place you reside, the carbon level of your home and according to some suppliers, the level of beneficial impact the insulation will have on your home. In order to have a free external wall insulation installed, you must either be the owner of your home or at least obtain the go ahead from your landlord before any external wall insulation activity can be made.

Good news is, if you fit the aforementioned criteria and you’ve already installed an external wall insulation, you just may be entitled to receive a refund for the good job done. However, to really find out if you’re eligible, we’d recommend you get in touch with your supplier directly. Also, the Energy Saving Trust (EST) can direct you to some organizations who can assist you in the determination of your eligibility.

As a home and property owner living in England, you can also check out the Each Home Counts Advice Website which is committed to giving impartial energy efficiency advice.

At the end of the day, if it turns out you happen to be ineligible for a free external wall insulation, you can still go ahead to contact a professional installer for a help at a competitive price to enjoy the several benefits that comes with home insulation.

What time can builders start work?

The periods at which noisy work is permitted do vary across the nation because the Control of Pollution Act 1974 provided Local Authorities with the authority to regulate noise from construction sites and similar areas. At the same time as these do differ across unalike councils, the average hours throughout which noisy work is tolerable is usually between 8 am and 6 pm from Monday to Friday. This is usually based on the impression of ‘noisy work’ being carried out, so labours could start earlier to prepare things for the day but then not start carrying out their work until 8 am.

On Saturday’s builders are usually allowed to work between 8 am and 1 pm, but this can differ to some extent with different councils. It does mean that workers can start at the identical time as the rest of the week, but they are generally required to finish a lot prior. On Sundays and Bank Holidays there is not as much of detailed direction on hours, but most councils say that there should be no noisy work taking place. Although these are decent strategies, it is worth examining your Local Authority website as they can change slightly. Noisy work is commonly described as ‘noise audible at the site boundary’ and it may be the case that workers are there outside these hours but are setting up before carrying out noisy work.

Local Authorities also recognise that now and then it is unescapable to work separately to these hours, such as work on railway tracks that must be done when trains are not running. Though, local councils do have the authority to serve an announcement on individuals carrying out building or demolition works and tell them how the work should be carried out to evade a possible lawful noise irritation.

How to renovate a house?

As with every home development project, a home makeover comes with heaps of preparation and, hard work, but it is a remarkable way to breathe new life into an old home.

RESEARCH PERIOD FEATURES AND SAFEGUARD THEM

Get to know your household better, the time it was constructed in, and the kind of individuals who would have lived there. The greatest tactic is to repair current structures, make the house dry and safe.

CHECK FOR RENOVATION RESTRICTIONS BEFORE YOU START

There are certain restrictions that don’t allow you to remodel your house after a certain extent, it should be made clear to you when you purchase the property but if you are unsure about the regulations you should check them up, as it is a criminal offence to carry out unauthorised work to a listed home. Restrictions in Conservation Areas generally affect only the exterior of the property as the intention is to ‘preserve or enhance the character or appearance’ of an area, but the right to develop your house will be affected. This means the kind of work that you could have easily completed in a different location may need certain planning and even permissions to complete in your area.

CREATE A DESIGN FOR YOUR HOUSE RENOVATION

It is very important that you take your time to perfect the design. This will help to ensure that the finished work is in tune with your needs. You will also need to figure it out how the changes might play with the original building.

FIND THE BEST CONTRACTORS FOR YOUR RENOVATION

If you are planning on managing the renovation project yourself, it is advisable to ask from friends or family who have renovated their house before and have undergone a similar experience. They can help you find the right architect and builder. Or else, you can always opt for a project manager.
