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 underpinning last

Have you been advised by a structural engineer or a surveyor that your building needs to be underpinned? Well, this might just have you wondering what underpinning really is and how long it lasts. In this post, we’re going to tell you more about underpinning to help you make the best-informed decision possible moving forward. Let’s take a look!

Basically, underpinning refers to the incorporation of one of various methods to reinforce or repair the old foundations of a building or structure mostly to remedy or avoid subsidence. Now, subsidence can be caused as a result of poor soil quality, increase in the load on the foundation like adding a new storey, excavations below the building as well as inadequate foundation which is more common in older buildings. When an underpinning remedial work is carried out, there are a plethora of benefits that comes with it. It’s preserves the structural integrity of your building by strengthening it, make it a lot more attractive, increases the property’s value and makes it a lot safer for both you and your loved ones. So how long does underpinning last?

Well, many underpinning contractors will offer you a 10-year guarantee of its underpinning solutions for defects. Primarily, there are two reasons why underpinning can fail which is poor installation and fresh issues arising or unforeseen circumstances. While the first is an issue that can be avoided by employing the services of an expert contractor who possesses vast experience and knowledge in the field, the second can not be avoided. However, in the absence of the unforeseen issues, underpinning is expected to last for the natural life of the building, so far it has been expertly installed.

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.

when is underpinning required

If you’re currently experiencing some structural issues with your building or property and you’ve heard a thing or two about the several benefits associated with getting underpinning done, you may be wondering if underpinning might just be the answer to your worries. Well, one thing you should when it comes to underpinning is the fact that, while there are some structural issues that may actually warrant an underpinning job, there are also some situations that can not be fixed by underpinning. In this post, we’re going to consider the events whereby underpinning of your house will be required. Let’s take a look!

First and foremost, you should know that underpinning isn’t required for issues related to slab heave. Footing movements which are likely to reverse normally occur when the content of the soil moisture changes unevenly which gives rise to slab heave. This movement results for a reversible effect.

Generally, underpinning is done to remedy problems related with the movement of the footings of a building or property, but as stated above – not all movements require underpinning. So, when is underpinning required? More often than not, a situation that’s resolved by underpinning is the event whereby the footings of a building or structure drops or subside as a result of some reasons that are irreversible. For example, footing movements caused by a footing set on a soft or loose soil which may be irreversible.

In the event whereby the footings of your house haven’t been installed as deep as required during the initial construction, then you will need to have your building underpinned to make it more stable. If you’re also looking to increase the load on your foundation like adding another storey, you may also need to have your house underpinned to support the extra weight added.

Do I need my neighbours’ permission for an extension?

Well the reality is, sometimes, neighbours just don’t get along. With several individuals living in close proximity, it’s little surprise they tend to get on one another’s nerves from time to time. However, there’s a difference between having a tiff and being able to transform your house the way you want without having to obtain your neighbour’s approval.

The short and simple answer to this question is, not necessarily. However, you must first educate yourself by thinking about your extension and how it affects the houses around you. We’d strongly recommend you talk proposals through with your neighbour so as to avoid possible conflicts later. There are a number of reasons why your neighbour can protest to your new home extension plans. Let’s take a look!

 

  • In the event whereby your new extension is blocking their view or providing an unwanted shade on their property. Here, they have a legitimate reason to protest as no one would want their once sunny garden suddenly covered or plummet into shade.
  • In the event where it leads to a loss of privacy. For instance, if your new extension possesses a window which overlooks the neighbour’s property in any way. This is likely to be taken as an invasion of privacy and that has a little to no chance of being a welcomed idea.
  • If it’s a major project and going to take a lot of weeks before completion. The noise generated, especially when your neighbours are enjoying your summer holidays or weekends, can make their gardens not as relaxing as it used to be.
how much does a garage conversion cost?

Are you looking to create some more space in your home with your garage being almost dispensable? If yes, then considering a garage conversion project may be the way to go. Unlike many other extension options, garage conversion does not take up an additional space as it only changes the current structure of the garage. As a result, the cost of completing a garage conversion project can be relatively attractive when compared to other space creating alternatives. So exactly how much would a garage conversion project cost? Well, there’s no precise answer for this as several influencing factors come to play. However, in this guide we’ll give you a rough idea of the average costs that you’re likely going to encounter. Some of the factors that can influence your budget dramatically includes the following:

• The size of the conversion. The larger the size of the garage per square feet, the more cost you’ll have to expend.

• The type of your property - listed buildings are usually more expensive.

• Your location in the UK. If you stay in London where there’s a higher demand, you’ll most likely pay more.

• You’re likely to pay more if a specialist knowledge is required.

• The amount of glazing to be installed

• Quality of the materials to be incorporated.

• Quality of the professional to carry out the installation service.

On average, when it comes to garage conversion projects, you’re likely to pay the following depending on the per square metre given:

• A single garage of about 15 square metre will cost within the range of £6,000 to £15,000.

• A double garage of about 30 square metre will cost within the range of £12,000 to £30,000.

how to tile a porch roof?

Tiling a porch roof is a very important but laborious and difficult task. A project of this magnitude will require a large investment in planning and preparation way before the actual installation process takes place. It can be a brand new porch roofing tile or a replacement of the existing one, either way it’s crucial to get the right technique. If you lack proper training or experience in this field, we’d recommend you hire the services of a reliable professional probably within your local area to guarantee the best results and to save yourself some time and money. This guide will give you a good insight into the porch roof tiling process. Let’s have a look!

• With the crown looking upwards, put the first tile on the batten and centre the tile from side to side.

• Hammer a 10d nail at the base of the tile and into the batten (make sure not to overdrive the nail).

• To provide a much needed support, apply a little mortar under the first tile.

• Identify the inner end of the first tile and place another tile on top. Take a measurement from the outer end and adjust the end of the second tile to fit.

• Just like you’ve done with the first tile, nail the second tile into the batten.

• Position two tiles at the both ends of the ridge and proceed with the installation just as you’ve done with the previous tiles.

• Take a measurement of the distance across the ridge from the first tile’s outer end. Once done, you can then calculate the number of tiles required by subtracting 16 inches from your measurement and divide the answer by 8.

• Beginning at the second tile on one end of the ridge, install the half the number of ridge tiles towards the centre of the ridge. Now install the remaining tiles working from the opposite end to the ridge’s centre. At the centre of ridge should be a key tile with mortar.

What cement should I use for bricklaying?

Cement is a crucial element in bricklaying that’s widely used in both construction as well as finishing works. Generally, they’re used to aerate concrete blocks, connect bricks, prepare plaster, floor levelling as well as the making of precast products. The major reason cement is one of the most common construction materials as its incredible ability to hold structure together. To get a cement plaster, you’d simply have to mix cement with both water and sand. However, when you mix cement with lime, sand and water, you’ll get a mortar.

For cements mortars to be used inside joints, you’ll have to include 1 part cement at the minimum to not more than 2 parts sand by weight which should be dry mixed and moistened with enough water to allow for troweling and packing without falling apart. Generally, the cement sand ratio in a mortar is in between 1:2 to 1:6. The cement and sand mix ratio is largely based on the importance of the project.

Cement provides a plethora of uses in bricklaying and these includes:

• Preparation of cement concrete

• Preparation of cement mortar

• Building fireproof and thermal proof structures

• Building chemical proof structures

• Serving as a grout material

• Building hydrographic and frost resistant structures

• Manufacturing precast members

• Constructing aesthetic concrete

• Constructing cement concrete roads

There are several types of cements with each having its specific purpose. For instance, the type of cement more suited to building a fire proof structure is a high alumnia cement and to build a hydrographic structure, cements like expanding cement, hydrophobic cement, pozzolana cement and quick setting cement are the best bet. Acid resistant cements are more useful in building chemical proof structures, portland cements are best suited to making grout materials, while coloured cements are preferable to building aesthetic structures.

are house extensions worth it?

Often referred to by many as the holy grail of home improvements, house extension comes with a wide range of benefits which makes it easy to see why the extension could be a great uptick in the potential price of your property in terms of sales. So if you’re looking to build a new home extension but still not convinced about the project, we’re here to help you. Being fully aware any home construction work is usually a heavy investment, there’s a huge need to be set on your decision before scheduling the commencement of any work. So are house extensions worth it? Below are some of the top benefits offered by house extensions to help you decide if it’s the most suitable route for you.

• Add To Your Home’s Value

Building an home extension is a great way to add value to your home before selling. Increasing the living space of your home is an incredible appeal to many buyers which significantly increases your property’s total value. However, you must ensure that the extension is impressively designed using top quality materials in order to generate more value.

• Good Alternative To House Moving

• You May Not Require A Planning Permission

You can extend your house and still not need to apply for a planning permission. To achieve this, simply comply with the laid down rules set under the permitted development rights.

• Extra Living Space

If you fill you’re starting to outgrow your existing structure and do not buy into the idea of moving, then your best bet might just be to extend your home.
