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 my garage conversion cause disruption to the rest of the house?

It shouldn’t do. Most companies will do all the interior work first, and the last job to do will be creating the opening from the house to the conversion. A reputable company will make sure they cause as little disruption as possible during this time.

how to repair a paved driveway?

Generally, a paved driveway is always subjected to regular usage and yours isn’t likely to be an exception, otherwise you won’t be here. Regular usage automatically necessitates regular maintenance of the driveway in order to extend its lifespan, make your property safer and add more value to it. This maintenance will involve a frequent inspection of the paved driveway so as to identify and repair divots, cracks as well as rutting. Paved driveways usually have a lifespan ranging between 15 to 20 years, but this can only be guaranteed when backed by regular maintenance activities. Failure to provide your paved driveway with a regular maintenance will lead to a rapid deterioration within just a couple of years after installation.

The issues commonly faced by paved driveways is usually different based on several factors such as the weather, your location, your property’s sub base as well as some other elements. The ability to identify the problems and solve or repair them on time is key to success while it’s also save you some time and money. In this article we’re going to look at how to go about do-it-yourself tasks that involves minor cracks. More intense damages are advised to be handled only by professionals.

✓ Prepare the area. Clear the debris, weed the plants or vegetation (if any).

✓ Use a strong spray from a garden hose to wash clean the cracks

✓ In the event whereby the crack is deep, simply fill it until it reach about a quarter inch of the surface with sand.

✓ Tamp down the sand to make it more compact.

✓ Apply a patching compound to the surface of the cracked paved driveway.

✓ Leave it for some time to cure.

✓ Once cured, you can then apply your sealant.

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.

can you render a house in winter?

Aside from the cold weather not being the most pleasant condition to work in, the winter weather can also cause a lot of problems for construction workers and even more so when you’re working with render. Poor weather conditions can generally cause a lot of harms on the final finish of a render. Below are some of the reasons why you should not consider rendering in a bad weather.

✓ Lime bloom. Render can be impacted by lime bloom as they are subjected to damp conditions and low temperatures while curing. This is due to the fact that cement are intolerant to slower drying conditions especially immediately affect its application.

✓ Top coats can be compromised. Coating are likely to get washed off before they’re even afforded the chance to set if drying conditions are low.

However, because its cold out there doesn’t necessarily imply that work must stop. It’s very possible to render during the winter months but to avoid potential pitfalls, we’ve got some tip that can be of great help. Let’s have a look!

✓ Check the weather forecast. Determine the drying and curing time and watch the forecast for the temperature dropping at night.

✓ Select the most suitable render. There are renders that are suitable for application in low temperatures to about 5℃ or even as low as 1℃. These types of render are fast setting which makes them perfect for the cold condition.

✓ Watch out for frost. Frost and render are enemies. Therefore, it won’t be wise to work with frosted materials, on frosted subtrates or apply below the recommended temperature that’s written on the product’s datasheet.

✓ Protect the finish. Make use of artificial enclosures around the scaffolding to battle adverse weather conditions.

How long does it take to install insulation?

External wall insulation will usually take longer to install. The rep or installer will be able to advise you when quoting for the job how long this will be.

where to start with a house extension?

In this article we’ll walk you through everything you need to consider and put in place before commencement of your home extension project.

• Is the extension worth it?

Before breaking the bank, you must be sure that the project will add good value to your home. In terms of “value, this is not only limited to the financial gain after disposal of the property, but also several other juicy benefits to be derived from extending your home like an extra living space for the household to spread out 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.

It’s very important to discuss your plan with your neighbours before applying for a planning permission and communicate about the concerns they might have.

A fencing contractor will be able to advise you on the best materials from the length and requirements of a new fence.
