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

Do bricklayers work in the winter?

Yes, bricklayers can work during the cold months, but it all depends on the type of work involved. For instance, residential housing maintenance works such as tuck pointing deficient mortar joints on exterior walls and columns as well as rebuilding of chimneys are best tackled during summer or simply put, the warmer months of the year. This is is mainly because the best results for these activities are achieved in the warmer months and several bricklayers will agree to this fact.

Mixing of mortar using anti-freeze technique to counter-act the effects of a cold weather can lead to white marks trailing down the brick when warmer temperatures comes knocking. As a result, even mortar mixing should be done at temperatures exceeding zero degree farenheit which will hold no serious consequences if the temperature should change to a little bit below the norms. During the winter, a good technique that can be incorporated to when mixing mortar would be to mix them in smaller quantities in a warmer environment. These small quantities will immediately be fed by the labourers to the bricklayers and in such circumstances, the mixed mortars will not be subjected to a freezing temperature for too long.

Generally, it would be very unwise to consider any bricklaying work to be done whenever the temperature jumps to a certain level which would be considered to be very inconvenient to work in. Interior works like remodelling of fireplaces can be tackled so long there is a warm space to mix the mortars while also keeping the materials at an indoor temperature. Bricklaying works that have, however, been completed during the colder months should be subjected to a very close inspection as well as looking for potential damage that can be caused to existing works as a result of the harsh weather.

How to plasterboard a brick wall?

How To Plasterboard A Brick Wall

Do you want to cover your brick wall with plasterboard? The key to success here is the preparation. You must ensure that brick wall is prepared well enough to receive the plasterboard. To get started, there’s the need to attach wood furring strips to the wall which serves as studs in a wood frame structure. This way, the plasterboard will be prevented from getting in touch with the brick. You can always hang pictures or any other forms of decoration in between the gap between the walls. Let’s have a look!

lAttach Furring Strips

• Get a 2 inch by 4 inch wood stud and apply a bead of construction adhesive.

• Using a masonry bit, drill a pilot hole through the wood stud’s base as well as the brick wall.

• Hit a 3 inch fluted nail through the hole using a sledgehammer

• Using a construction adhesive, bind a horizontal 2 inch by 3 inch stud to the upper edge of the wall.

• Using an adhesive, bind the length of a 2 inch by 3 inch stud on its wide side.

• Use a masonry drill to drill a hole on the wood stud and 1 1/2 inches into the brick wall.

• Hit a 3 inch fluted nail through the pilot hole.

lApply Plasterboard

• Hold a plasterboard sheet against the furring strips.

• Use plasterboard screw to hold the drywall sheets in place.

• Use fibreglass to cover the joints where the two plasterboard sheets meet.

• Use a thin layer of the joint compound on the tape. Once done, screw it using a 6 inch taping knife, then allow to dry overnight.

• Use a sandpaper to smooth the joint compound.

• Use a fresh coat of the joint compound to block the holes and joints. Once done, allow the compound to dry.

• Use a light sandpaper to smooth the final coat.

Plasterboarding a brick wall is a simple task but the preparation part must be done right to protect your investment. Therefore, we’d recommend you hire the services of a skilful professional, who can guarantee the best results especially if you lack enough training and experience to carry out a DIY project.

how thick should loft insulation be?

Over the years there has been an increase in the recommended thickness of loft insulation by the government. Obviously, the reason behind this is pretty simply - the thicker the layer of your loft insulation the bigger your savings. The UK government is very keen to every house in the country to have loft insulation fitted where possible as it helps to minimize the heating demands of these properties. Households get to benefit from loft insulation in so many ways which includes reduced energy energy bills as well as having a home that stays at a more comfortable temperature for longer.

 

Generally, for the government energy efficiency is crucial as it implies that the highest demand ( which is usually the time of the day when gas or electricity use is at its peak ) reduces, since each building requires slightly less energy. Overall, that ultimately implies that new power plants don’t have to be built which is some nice cost savings for the government.

 

In the 1980’s, any thickness of loft insulation from 25 mm to 50 mm was considered the standard. But then, building regulations stated that homes should have as much as 100 mm of loft insulation. Over time, this gradually increased to 270mm for new builds and also recommended for other properties, although not essential. As a result of this, there’s always a need to check how much insulation you currently have in your loft before you decide to purchase more. You may discover that you already have something within the range of 20 mm to 200 mm up there and knowing this and the insulation values will assist in determining how much more you’ll need to purchase, if any at all. You should also note that some modern materials can offer the same thermal insulation whilst not being as thick.

Are barn conversions cold?

If you’re considering converting a barn or buying one, you shouldn’t need to worry about it being cold. This is because building regulations dictate that when you convert a barn, you need to insulate it to meet specific standards. However, it’s worth considering its heating system and ceiling heights carefully – some barn conversions are likely to take longer and be more expensive to heat up than others.

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.

do i need planning permission to render my house?

If you’re considering rendering your house or property, then you’d most likely want to know whether or not applying for a planning permission will be needed. In several cases, planning permission will not be required for the maintenance, repair as well as replacement of the existing render on your building. These activities are covered by what’s called “Permitted Development Rights, which allows you to carry out some activities without having to apply for a planning permission but always subject to following some strict guidelines. For rendering, as long as the material (render) possesses an identical appearance to those existing on the house as well as same colour, then you will not require a planning permission. However, there are a number of projects that have been highlighted in which a planning permission would be required. These includes the following:

✓ Re-rendering in a colour that different from the original one used on the house or building.

✓ Rendering over brickwork which was not originally covered.

✓ Rendering over pebbledash

✓ Removing pebbledash and replacing it with render.

Another exception to the Permitted Development rights are for houses in conservation areas, national parks or areas of outstanding national beauty.

Although, you wouldn’t normally require to submit a planning application for approval before you apply render, but in truth it’s actually a bit of a grey area which isn’t totally clear and doesn’t allow for much freedom or creativity. And due to this fact, homeowners who wants an absolute peace of mind may opt to apply for planning permission just in case. It’s also worth noting that whether or not a planning permission is required, a huge rendering work will need to comply with building regulations which includes the need to insulate walls on the inside or outside as part of the work on several older properties .

how much value does a loft conversion add?

When its impossible to build out and create more space sideways, why can’t you look upwards? As more and more homeowners in the UK are carrying out their loft conversion project, one question that keeps popping up is the amount of value the loft conversion can add to their homes. However, this is a question that is impossible to provide a single and precise answer to. This is because the value that’ll be generated by a loft conversion is largely dependent on a wide range of influencing factors. To give you a vague idea of the loft conversion value to a property, we’ve put forward a research carried out by industry experts so you can know what you’re in for.

Nationwide carried out a research which shows clearly that a loft conversion including an additional bedroom as part of the building plan will increase a house’s value by up to 21 percent. Since the number of rooms a house has is one of the main metrics for house valuations, loft conversion comes in pretty handy as it’s a great and easy way to convert your house from a 4 bedroom house to a 5 bedroom house prior to sale.

Apart from the financial value aspect, loft conversion also adds more value to your lifestyle which is very unlike nearly other financial investments you can make. More space in your house automatically means more storage or a new room as you wish. A new room can be for a growing family or probably to serve as a guest room. It can also be used as a study space or even an office especially with the rapidly growing rate of people working from home. With loft conversion, the possibilities in terms of value are simply endless!

How to find a builder to refurbish my house?

After making the decision to refurbish your home or property, the next obvious step is finding the right builder to get the job done. The process of getting a good and reliable builder can be a very tricky one especially when you don’t plan ahead. And in truth, the outcome of your house refurbishment project can only be as good as the contractor your hire. Consequently, finding the perfect builder for your task should be a top priority to get the best return on investment. Here are a few sources that will put you in the right direction to finding a reliable home refurbishment company.

✓ Friends, Relatives & Neighbours

If you have a friend, relative or neighbour that have recently completed a home refurbishment project, you can go for a visit to check out the work done. If you’re pleased with the work, you can proceed to ask about the work ethics of the builder and get the contact if satisfied.

✓ Internet

With the rapid rise of online technology, there’s hardly a service you can’t find on the internet. Websites like HomeAdvisor have been helping people find their desired service providers with relative ease for so long. To get the right building contractor online, it’s advisable to check reviews as well as testimonials before moving forward. Nowadays, you’re most likely going to find so many positive online reviews as some businesses now go to the extent of dubiously writing good reviews for their companies. As a result, it’s recommended to pay closer attention to the negative reviews and check if it’s something you can cope with before hiring a contractor.

✓ Store Contact Lists

You’ll discover a long list of building contractors on several stores trading building materials. These builders may not be affiliated with the store owners, but many stores see it as their responsibility to point you in the right direction so that the building materials acquired from them can be put to good use.
