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 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.

Can I extend the front of my house?

When it comes to extending a home, the rear of the house often comes to mind a lot more than the front. However, this doesn’t mean that you can’t extend the front of your house. This can be done either as part of a renovation project whereby the entire house is incorporated or it can also be done in isolation. It’s possible to extend the front of your house without the need to apply for a planning permission, however, there are a bunch of limitations you’d have to comply with if you wish to carry out with such a project. Sometimes, this may imply that extending to the front of your home is more tedious and tasking than extending your home’s rear. So exactly how far can you extend the front of your home without planning permission?

 

The short and simple answer to this question is 2 metres square area with a height not more than 3 metres. Generally, you do not need a planning permission to build a front porch as long as its area doesn’t go beyond 2 square metres from a public road or walkway. Also, a tiled or slated roof can be as much as 4 metres but other roofs must not go beyond 3 metres in height. If you want to extend the front of your home beyond the restrictions specified, then you’ll have to apply for a planning permission.

 

Extending the front of home can be quite costly, but this can be controlled by not building to the extension to the highest specification, not including an extension on kitchens or bathrooms and more.

• Who will manage the building work?

If your home extension project is designed and built by a professional company, they’ll be responsible for the management. However, if you decide to use an architect or designed it yourself, you’ll have to hire a main contractor to manage the build.

• How to set the budget?

There are so many factors that can affect the cost of an extension, so it’s better to get the costs from your builder before proceeding.

• Do I need yo inform my home insurance firm?

Absolutely! This is very important as the new extension may affect the rebuilding cost of your property which could have an impact on the policy premium.

How to fit plasterboard?

How To Fit Plasterboard

If you’re planning to renovate your house, then here is a must-read guide! Fitting of plasterboard is a crucial step when it comes to renovation. If you’re bringing down an existing lath and plaster for an upgraded surface or adding a new wall, a plasterboard is required for your project to be a true success. If you’re a novice with no prior practice or experience, you can protect your investment by hiring the services of a professional plasterer to guarantee the best results, the first time. However, we’ve put together this guide to give you an insight on how the plasterboard fitting process is done.

To get started, you’ll need a power drill, hammer, plasterboard nails or screws, broad knife, utility knife, measurement tape, pencil, ladder as well as a joint tape.

Before proceeding, you need to identify the number of plasterboard sheets needed to commence the project by measuring the height and width of the wall as well as calculating the square footage. If you possess a stud timber wall, the steps below will get you the best results.

• Measure the walls and mark the plasterboard where you’ll make the cuts. Start with a full sheet and cut pieces down in such a way that would fit

• Score the front paper of the plasterboard with utility knife. Fold the sheet to get a clean cut through the board and make use of the knife to the remaining paper.

• Place the first sheet against the wall and use an offcut to prevent the plasterboard from touch the floor.

• Make the plasterboard rest snugly against the wall in position and screw it firmly on each stud. Once done, fasten it at all the sheets’ edges and in a line down the stud to make for a firm connection. Follow the same process for the remaining plasterboard sheet till the wall is fully covered.

do i need planning permission for a garage conversion?

Are you thinking about converting your garage into a new space? Be it a new bedroom, gym, library or playroom, one thing you’ll have to consider before getting started is whether or not you’re going to require a planning permission. Unlike extensions that needs additional space, garage conversion is all about changing the existing structure of a space that’s already available to you - your garage. As a result, these projects are mostly covered by a planning policy that’s a bit different.

For a garage conversion, it’s very unlikely that you’ll need a planning permission. As a matter of fact, only 10 percent of garage conversions has been estimated to need a full planning permission, with the others coming under the permitted development rights. The permitted development rights, however, only provides coverage for home improvements that’s internal which implies that so far you’re not trying to enlarge your garage, you’ll not require a planning permission. But if otherwise, you’ll have to submit an application before commencing your project.

If you’re looking to comply with the permitted development rights, then your project must comply with some specific guidelines. These rules include the following:

• The work should be internal. No plans to enlarge or extend the existing garage.

• You should make sure that the materials used in carrying out the garage conversion is the same with the materials used in building the existing house.

• The building should not be extended.

You may, however, require a planning permission if you’re going to change a detached garage into a living space which could be a bedroom, small annexe or a living room.

Some houses excluded from the permitted development rights include flats, listed buildings, some new developments and most homes in a conservation area.

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.

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 to repair sunken concrete driveway?

How To Repair Sunken Concrete Driveway

If you have concrete driveway that’s cracked, uneven and mostly especially sunken, you’d know how distasteful it can be just viewing it on your property. A sunken concrete driveway is most likely caused by rainwater erosion removing the soil under it or a big root under it which as rotted over time. Another possible cause of the sunken concrete is an improperly prepared base which implies that the soil beneath wasn’t fully compact when the concrete was poured on it. Later on the soil beneath will eventually settle and shift below the concrete driveway which weakens the integrity of the entire driveway, making it more vulnerable to cracks, unevenness and sunken.

Two ways in which you can fix this problem includes either demolishing the whole driveway, re-compact the soil underneath and fill with new concrete or repair the entire driveway using an easy process called slabjacking. In this article, we’re going to look at the slabjacking repair process as it’s significantly less expensive than the demolishing approach and will also cause minimal disruption to your lifestyle.

Also referred to as mudjacking or concrete lifting, slabjacking is simply a process used to float your existing concrete back to its original position. If you are not a competent DIYer or lack confidence to pull this off, we’d recommend reach out to a professional for help. If otherwise, then you can practice the slabjacking process given below.

✓ Drill holes through the slab.

✓ Pump grout mixture through the holes. This mixture will spread out beneath he driveway and raise it up.

✓ Lastly, fill the holes and level the concrete driveway surface.in such a way to hide the signs of the repair made.

This is a process that works to efficiently get your driveway back in a top condition relatively quickly.
