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

Will insulation save me money on my energy bills?

This depends on the amount of insulation already present in your property. However, adding insulation has been proven to improve the energy efficiency of your home and decrease your heating bills, this is more obvious in older properties or where single glazing is still in situ.

how much to board a loft?

How Much To Board A Loft?

If you stay in a building where the space meant for storing stuffs is not sufficient, boarding your loft may be just the perfect solution for you. In several homes, the space is already present, and all you have to do is to make it more usable by boarding it out. This is unarguably one of the easiest and quickest ways to create storage space in your home.

Boarding a loft comes with a number of special benefits which includes:

• Assisting to declutter our living spaces and makes for a more spacious home.

• Creating a usable space whereby all seasonal items can be stored.

• Assisting to reduce heating bills as it prevents the loss of heat. When your loft is well boarded and insulated, it’ll help trap heat and prevent it from escaping via the roof.

• Adding to your home’s value by making your attic a very useful space for storing items.

• Helping to create a quiet space which can used for relaxation or getaway purposes and of course, this will require a bit more structural work.

So now that you’ve learnt a few of the benefits associated with boarding a loft, how much will it cost to have one made? This depends on an array of factors which includes the size of the space needed, the type of materials and labour cost.

Overall, a standard semi detached building will feature a lot of space of about 40 sqm to 50 sqm in size. There’ll be a need to add to the height of the floor joists before installing the chipboard decking boards. This job size should cost within the range of £1,000 to £1,500. It’ll require just a two-person team that are fully equipped and well versed about the processes.

Are barn conversions VAT exempt?

If you’ve converted a non-residential barn into a home, you might be able to reclaim some of the VAT that you’ve paid for your project. This includes money spent on:

• Construction materials

• Flooring

• Light fittings

• Kitchen units and worktops

• Electrical, heating and plumbing materials

To reclaim your VAT from HMRC, make sure you request and keep all of your invoices. You’ll also need proof of planning permission and evidence of completion. You should then submit your claim with all relevant paperwork within three months of receiving your completion certificate. You’re only allowed to submit one claim, so you’ll need to make sure you get it right first time.

What is plasterboard?

What Is Plasterboard?

The plasterboard is unarguably one of the most common building materials across the globe. Sometimes referred to as gypsum board, gyprock, drywall or wall board, the plasterboard is mostly incorporated for ceiling cladding and interior walls in several homes and offices in recent times. However, despite its global acceptability, it’s a very misunderstood building material.

The plasterboard is manufactured using a gypsum core with a heavy paper covering both sides of the sheet. The measurement of a standard plasterboard sheet is a length of 2.4 metres in and a width of 1.2 metres, with a thickness of about 13mm. The board usually have either a bevelled or a bit flat edge. The bevelled edge makes it easy for the installers to use a plaster to smooth out the surface after nailing the sheets to walls and ceilings as well as taping the edges.

The plasterboard comes in different types. Although various manufacturers provide a unique name for their products, but they’re all included in one of the following categories:

• Water Resistant Plasterboard - This type of plasterboard are best suited to be used in water areas like bathroom, laundry rooms and kitchens.

• Acoustic Plasterboard - Due to its sounding proofing qualities, this type of plasterboard is preferred to be used in home theatres or noisy areas.

• Flexible Plasterboard - This is to be incorporated on curvy surfaces.

• Fire Resistant Plasterboard - Just like the name implies, this type of plasterboard is best suited for use in high fire hazard areas.

If you’re about to kick start some small renovations around your house or office, using a plasterboard to clad your walls is a very simple and worthwhile task. However, if you want to do major renovations or need to apply plasterboard to your ceiling, the best option would be to leave it to a seasoned professional.

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.

Can cladding help with a damp problem?

External cladding will have an impact on a damp problem. However, it’s important that cladding is the last part of a damp treatment, as installing cladding over a damp wall will make the problem worse. Do not cut corners or try to remedy a problem with the cheapest solution, a damp proof course may need to be put in place before cladding.

Does cavity wall insulation lead to damp problems?

Insulating a cavity wall should not affect the damp proofing of the wall. All insulation approved for use in cavity walls has been tested to ensure that it does not allow damp to pass through the wall. Some walls which receive a lot of wind driven rain are unsuitable for cavity wall insulation.

how to insulate a loft?

Do you know about 25 percent of heat that escapes from an uninsulated house are lost through the roof? Fortunately, roof insulation is something that can done by all DIYers irrespective of their experience levels. However, if you happen to lack the confidence necessary to pull off this, then it’s strongly recommended that you hire the services of a professional who can guarantee the best results and also save you time and money that could arise from potential cost mistakes. Let’s take a look!

  • Clear out all clutter. This involves taking out all the rubbish and clutter from the loft. In order to work effectively, you’ll need a totally clear and empty loft space.
  • Ensure that there’s sufficient insulation. The importance of a good ventilation cannot be overstated. Poor ventilation will result in forming of condensation and this condensation can make the roof timbers rot and compromise the structural integrity of the entire roof. If there are no roof windows which is the easiest way to provide a loft ventilation, the next best option would be to follow the loft floor along to the point where the roof comes down to meet it. There should be a gap at this point, also referred to as the eaves, between the outside wall and the underside of the roof.
  • Measure your loft area. Take a measurement of the loft space in order to calculate the amount of insulation as well as the type you need. If you’re not sure, always get more that it’s required as skimming on the amount you use will only back fire in form of increased energy costs
  • Check for water pipes.

 

To get started, simply make sure all cracks and gaps in the ceiling are filled using a standard filler or decorator caulk. Once done, clean the gaps in the joists and even to the point of hovering all the dust up. Finally,check for the hazards that can cause you problems before laying the loft insulation.
