How much do Builder services cost?

How much do Builders cost? Prices for Builders in 2026 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

Can cladding help with a damp problem?

External cladding will have an impact on a damp problem. However, it’s important that cladding is the last part of a damp treatment, as installing cladding over a damp wall will make the problem worse. Do not cut corners or try to remedy a problem with the cheapest solution, a damp proof course may need to be put in place before cladding.

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.

How to plasterboard a wall?

How To Plasterboard A Wall

If you’re looking to plasterboard your wall, one of the essential things to have in mind is that the plasterboard must be hung horizontally and not vertically. Due to the way they’re manufactured, plasterboard sheets normally possess a “grain along the length. This implies that, it’s only when they’re firmly placed perpendicular against the wall that they’re able to achieve their maximum strength. Materials you’ll need to complete this task includes: Tape measure, stanley knife, pencil, spirit level, drill driver or screw gun, surform, drywall screws and handsaw. Now let’s have a look at the wall plasterboarding steps!

• To plasterboard a wall the first step to take is to place each board in such a way to make the edges the centre of the noggins and upright. Also, the the adjoining walls and door openings should fit closely to the edges.

• Work from the door opening to the ending wall. From the the stud’s edge to the noggin’s centre, use your tape measure to measure a cut board and as a rule to mark up.

• Place your spirit level on the marks and use the Stanley knife to run a line along the intended cut. Once done, turn the board on its edge and give a sharp push on the back to split.

• Cut the paper left with the knife after folding the split edge back on itself. This way, you should get a nice and clean edge.

• In its right position, place the board up against the studwork. Install the screws on the board’s edges where a noggin or upright can be seen.

• Mark lines down across the board at the stud’s centre.

• Cut the end boards to length.

• Install the remaining boards as mentioned above. While doing this, make sure the factory edges are together.

• Cut any board extending into an opening and finish the edges using a surform.

We’d recommend you hire the professional services of a plasterer for the best results especially if you lack the necessary training or experience. Plasterboarding a wall can be a tricky challenge and you’d save yourself some time, money and effort by getting it right on the first trial.

do i need planning permission for a loft room?

Do I Need Planning Permission For A Loft Room?

The answer to this question is maybe. Generally, loft rooms are covered under “Permitted Development which means you won’t need to apply for a planning permission to build a loft room. This is like an advance planning permission provided by local authorities to allow some particular building works to be done such as loft conversions, rear extensions and more. When you’re covered by a “Permitted Development, you’re given the free range to oversee your home’s development without much interference from the regulations or the council. However, for permitted development to apply, there are some specific criteria that must be met. Therefore, if your loft room does not meet the following requirements given below, then you must complete a planning application before proceeding.

• In a terraced house, the converted loft space must not be more than 40 cubic metres.

• In a detached building or semi detached house, the converted loft space must not be more than 50 cubic metres.

• The existing roof slope at the front of the house must cover the extension made.

• The extension should not increase the height of the roof in any way.

• Verandas, balconies and any other structures of this nature must not be included in the extension’s plan.

• The side facing window openings should be at a minimum of 1.7 metres above the ground. The windows must be obscured as well.

• The roof extension should be set back as far as practically possible. It should be at a minimum of 20cm from the current eaves.

• The roof extension should not overhang the house’s roof or it’s wall.

• The materials to be incorporated must be the same or at least similar to what you already have on the house’s exterior.

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 much is a loft conversion?

With the ability to add approximately one third of your existing living space ( by converting your old, unused attic) to your home or property without having to let go of your garden, it’s quite easy to see the reason why loft conversion has rapidly grown to become one of the most popular home improvements in the UK. However some homeowners usually shy away from the idea simply by looking at the perceived high cost of carrying out such a project, despite several researches showing that loft conversions offers the best rate of return on initial investment when compared to the other home improvement projects. So exactly how much would it cost to carry out this project?

Just like several other home improvement projects, the cost of a loft conversion varies greatly depending on a wide range of influencing factors. These factors include the size of your home, how old your home is as well as the quality of the fixtures and fittings you want to install. For instance, a high end bathtub alone can cost you thousands of pounds, meanwhile you can also construct a full bathroom suite on just a couple of hundred pounds. However, to give you an idea of the minimum cost of a loft project we’ll look at the most popular types and the minimum cost of each.

✓ Internal Loft Conversion - The most affordable type of loft conversion tends to start from £25,000 and above.

✓ Dormer or L-Shaped Dormer Loft Conversion. These are the most popular types of loft conversion. Dormer price tends to start from £35,000, while the L-shaped dormer starts from £45,000.

✓ Mansard Loft Conversion - This involves replacing the entire side of a sloping roof with a vertical wall and flat roof. It requires a planning permission. The type of loft conversion usually starts from £45,000.

✓ Hip To Gable Loft Conversion - This usually starts from £50,000.

does a kitchen extension add value to your house?

If you’re planning to add a kitchen extension to your property or perhaps you’re simply looking for ways to increase the value of your property, this is one of the common questions that usually pops up. A simple answer to this question is yes, a kitchen extension will add value to your house. With a kitchen being one of the most frequently used room in a house, adding an extra space to the commonly used room can only increase the value of the entire property. However, to determine the value added by such an extension, there’s a need to calculate the cost of setting one up first.

Kitchen extension costs are greatly influenced by a wide range of variables such as the size, type of the extension and specifications, your location, professional fees, materials used and more. Overall, the type of the extension you opt for will play the most significant role in the determination of your kitchen extension cost. Here, we’ll be looking at a single storey kitchen extension.

For a single storey kitchen extension, you can expect your home’s market value to increase within the range of 5 percent to about 10 percent. When trying to calculate the cost of kitchen extension, it’s crucial to take into account how much value it’ll add to your home so as to make sure that the amount expended will not outweigh the expected value to be added by the project.

For a more accurate idea, there’s the need to consult local estate agents. However, for a much needed guideline, single storey kitchen extensions are usually able to add about 5 to 10 percent to a home’s value, while double storey extension should be up to 20 percent. But as stated earlier, this will depend on several variables.

How do I manage drainage for my paving?
