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.

Have you decided to improve your property instead of moving? The common problem most homeowners face after deciding to embark on a home extension project is not knowing where to start.

Before breaking the bank, you must be sure that the project will add good value to your home.

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 long will a loft conversion take?

It depends on the style and size of the conversion, but in general, a loft conversion will take between 1-2 months. A loft conversion is a substantial building project, and plans will need to be drawn up. This may add to the time it takes to complete your loft conversion.

What is the ratio of sand and cement for bricklaying?

When it comes to laying of bricks, it is essential to get the right mortar mix. It is vital, be it for construction or maintenance projects, so far mortar is required. There are several materials incorporated in getting mortar which includes both cement and sharp sand, soft sand or plasterer’s sand and lots more. Here, we are going to look at the right ratio for cement and sand mix in bricklaying.

Cement include ingredients such as iron, aluminium, as well as silicon and it is mainly used for mortars like aerated cement mortar, Portland cement mortar and gauged mortar. Sand, on the other hand, comes in different forms such as sharp sand, soft sand and plasterer’s sand. The sharp sand consists of a larger grain size than the others and is usually incorporated in the construction areas that requires more strength as well as flexibility. Soft sand is the most common one used in mortar and it’s also referred to as bricklayers’ sand. These are used to make all types of mortar. Finally the plasterer’s sand which neither has the sharp sand’s coarseness nor the fineness of the soft sand, but can also be used for any form of mortar.

Cement and sand mortar is used for a plethora of bricklaying jobs serving as a glue for bricks, walls and pillars, while also repairing or maintaining old listed buildings. The preferred ratio here is 1:3 to 1:5 of cement and building sand. Meanwhile, to get a sand cement mix, essential materials that are required includes water, soft building sand as well as cement. However, you must also note that a sand and cement mortar is not used for structural projects, rather a concrete ratio is used.

how much is a ground floor extension?

Generally, extensions can be a very tricky undertaking - where it can be quite difficult to have a clear comprehension of the rules, regulations as well as costs. Therefore before you rush in to kick start your ground floor extension project, it’ll be wise to get a good grip on the cost. In this article, we’re going to give you a rough estimate of the cost of a ground floor extension. Let’s take a look!

Just like several other home improvement projects, the cost of constructing a ground floor extension is based on a number of things which includes the size, materials used, your location, the quality of the tradesmen or company hired and lots more. For instance, if you happen to reside in London, the cost of your ground floor extension is going to be a lot higher than the other regions.

The single cost of a ground floor extension should fall within the range of £1,500 per square metre to about £2,000 per square metre. However, if you happen to live in London or the South East, this price can reach up to £1,900 per square metre to about £2,400 per square metre. These prices are for good quality ground floor extensions only. Basic or low quality extensions would naturally cost less while superior quality extension will cost more.

Now looking at the size of the ground floor extension, if you’re looking for a size of about 5m x 5m, you can expect to pay a price within the range of £32,000 to about £36,000. And as usual, in London or the South East, this price can reach up to £50,000 or even more. And that’s just for constructing the extension. If the other relevant costs like the 10 percent to 15 percent professional fees for the architect, planning application (if needed), building regulations and more, the price goes up.

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.

Does a converted basement need windows?

Windows or lightwells can be a great way to introduce natural light into your basement, making it a more valuable, enjoyable space. However, they’re not always an essential requirement.

It’s important for your basement conversion to meet ventilation and fire safety building regulations. Windows can be a good way to do this, but they’re not the only option. Stack or mechanical ventilation, or ensuring that stairs up from your basement connect to an exit can be a good alternative.

So, while windows can be a great asset to your basement conversion, if you can’t afford them or they’re not structurally feasible, you can still create a basement conversion without them.
