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.

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.

• 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.

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.

Can my loft be converted?

Many types of loft are suitable for a loft conversion. In general, you will need at least 2.3 metres of headroom in your existing loft. This is to make sure there is enough headroom after the conversion. Speak to a conversion specialist about the probability and possibility of doing this in your house.

how much to re render a house?

Rendering of a house is one of those projects that can greatly improve the visual appeal of your home, enhance it’s energy efficiency, protect the brickwork from the elements and ultimately, add value to your home. Generally, the cost of rendering a house normally costs within the range of £25 to £70 per metre square, while the average cost house rendering costs stands at about £40 per square metre. Therefore, a 3 bedroom semi detached house will cost within the range of £4000 to about £5000.

The total cost of rendering a house is determined by a wide range of factors. These factors includes the following:

✓ Type of the rendering. There are three main types of rendering which includes sand and cement rendering, monocouche rendering as well as acrylic or silicone rendering. However, re-rendering applies to sand and cement sooner and it’ll also have to be painted every 3 to 6 years. Consequently, longer term cost can be higher when compared to the other types.

✓ Ease of access. Where your contractor will have to work around obstacles like shrubs or conservatory, this can make the cost a bit higher as it’ll take longer time to complete.

✓ Prep work. If the contractor needs to fill some cracks or perhaps an old mortar requires tuck pointing before rendering can be started, this will also affect the cost.

✓ Scaffolding. In the event whereby the job requires the use of scaffolding and you’ll have to hire one as a different cost, then the price will be higher.

✓ Your location. Due to the high standards of living and higher demands in areas like London or the Southeast, prices in these regions are usually higher than that of the other regions like Midlands and North.

Are barn conversions a good investment?

A barn conversion can be a great investment for lots of reasons. When done well, barn conversions can be great at holding their value, meaning you could sell yours for a great price. They can also look fantastic, often with period features coupled with large areas of glazing. This can make them a great place to live, especially if you enjoy being in the countryside.

However, barn conversions do have their disadvantages. They may require extensive renovation work to bring their energy efficiency levels up to standard, which can be very expensive. It’s also important to be aware of their location – they might be on a working farm or close to several other converted buildings.

It’s essential to get a survey conducted before you buy a barn you plan to convert. This can tell you about any structural problems it might have and give you an indication of whether you might be able to get permission to convert it. You can also buy barns with planning permission already in place.

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.
