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

how to refurbish your house?

If you’re thinking about refurbishing your house or property but don’t know how to go about it, then you’ve come to the right place. In truth, not every home refurbishment works goes in exactly the same order, however it’ll do you some good to abide by a specific plan in order to avoid both unnecessary works as well as expenses. For instance, how would it feel if you have already closed walls and paint only to realize that there’s a need to include a new plumbing stack that has to go behind the wall? Not good, right? Well, this guide is designed to help you avoid such frustrating situations. Let’s have a look!

✓ Establish a plan. This involves carrying out a good assessment of what you’d like to refurbish and set the priorities like deciding where to start and making sure you have both the time and budget to complete the project.

✓ Set a budget. Establish a final amount that’ll be the threshold to your spending. It’s always good to add an additional 10% to 15% to cover unexpected costs.

✓ Hire a contractor. Carry out a research, reach out to many contractors, compare their prices, work quality as well as integrity before hiring.

✓ Talk to your insurance company. Find out if you have the amount of coverage that suits your needs from your insurance company before and after your project.

✓ Secure permits and order materials. Make sure you check with the latest regulations before commencement. Once done, you can start ordering the required materials.

✓ Start demolition. This is optional as it only applies if space is being added.

✓ Work behind the walls. This include doing all the works necessary behind the walls like plumbing, electrical, heating etc.

✓ Paint and install flooring

✓ Fit in the cabinetry

✓ Add finishing touches. This includes the last details and decorations.

can i build a room in my garden?

The short and simple answer to this question is yes, you can build a room in your garden. In fact, if you want an additional space for a living room, dining room, games room, study room or perhaps you want something as cool as a pool house, then looking at your garden for a solution may just be the perfect answer to your need for an extra outdoor living space.

Outbuildings such as garden rooms do not usually require planning permission as they’re usually covered by the permitted development. As a result, making it even a lot more attractive to homeowners who would not like to pass through the stress involved or pay the money required to submit an application for planning permission. However, if you need your garden room to be covered by permitted development ( if it’s not a listed building or in a designated area), you must follow these guidelines:

✓ The garden room shouldn’t be in front of your home or property.

✓ The total area of your extensions, sheds and outbuildings ( which includes your garden room), must not go beyond 50 percent of the total land area surrounding your property.

✓ It must be a single storey that’s less than 3 metres high ( 4 metres for a dual pitched roof). And it must not go beyond 2.5 metres in height if the structure is within 2 metres of your boundary.

✓ The eaves must not go beyond 2.5 metres above ground level.

✓ It must not feature a balcony, veranda or any raised platform

✓ It must not be a self contained living accommodation.

The position of your garden room will be partly determined by the space available in your garden. If you need it to link it to your utilities then positioning it a bit close to your main house would be a cost effective choice unless you’re using off grid sources of power, heat as well as water.

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.

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 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.

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.

what are fitted wardrobes made from?

Storage space is a major consideration for most home buyers and even more so, when there’s the presence of fitted wardrobes. Fitted wardrobes can be installed in just about any room in the house and even in rather obscure places such as under the stairs, inside a loft, around chimneys as well as into alcoves. As a result, they’re important assets to have as they can go a long way to increase the value of your home or property.

Fitted wardrobes are usually made from various types of woods as well as wood finishes. Typically, they’re installed with either sliding or hinged doors depending on the space as well as the styling you opt for. Fitted wardrobes can be personalized through the addition of elegant features such as custom lighting, mirrors as well as internal extras like pull out shoe racks and pull down hanging rails.

For high end customized fitted wardrobe like Sharps, the best quality, most practical and also robust materials are being incorporated. They make use of the following materials given below:

✓ Fibreboard. This is a modern material that’s used for its ability to produce a smooth routed and detailed design. It’s also very solid and robust which makes it perfect for large furniture pieces as they don’t warp or dent. What’s more? Fibreboards meets the European forestry sustainability standards and it also allows for the board to be profiled with a top notch finish.

✓ Particleboard. This material is used for the parts of the furniture which will normally be cut in your home like facings and side panels. Due to it’s lightweight, they’re very easy to cut and doesn’t produce as much dust as other materials. The material is also a highly controllable contemporary material which can be precisely cut arounf skirting boards, covings as well as period features to ensure a perfect fit.

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.
