Bricklaying- 11 Mar 2023
The builder came to build a single skim brick wall to the side entrance of my house -: around 120 bricks. He agreed to £300 for labour including inserting a door. Upon arrival, of which he came on foot, he had no tools, no bucket, no drill, no ladder. He had to borrow all of my husbands equipment and sent my husband out for extra materials on two occassions. The lintel he asked us to order was the wrong size, we ordered one that was far too big and wasted more money due to him measuring up the job wrong - again a waste of money. Then, we had to drive him to toolstation to buy a brick cutting tool because of this using our own time and fuel. You would assume a brick layer would have tools if they are doing jobs privately - his colleagues excuse was we are just starting up our private buisness. He then started asking for more money and stormed off leaving all the rubbish behind even though we gave him the £300 as agreed prior to the job. The wall itself is okay but again at one point he refused to build up to the top because of a metal screw apparently impossible to remove, so yet again my husband had to assist with the job and removed the screw. Honestly more hassle than it was worth. Also the door was not fitted so now will need to pay someone else to do the job. I do feel bad for them that do not have any equipment but when you pay money for a job you do expect a certain level of service. I wish them good luck in the future and hope they take this advise on board.

Conversions - General- 17 Oct 2026
Argon is a very nice and helpful person, he has converted our 3 bedroom fire damaged bungalow into a 6 six bedroom, loft coveted bungalow. What he gave us in the end was definitely a 5 star building but the journey was stressful, some of his sub contracts left a lot to be desired Would I use him again? A BIG YES But I would definitely Spec the job better down to the last screw and get him to price it all as we did have some disagreements over what was in or out of the quote and be on site more to push it on and so as we did not run over the date given for completion These are most of the reasons I have given 4 not 5 stars At one point he did admit this was the biggest project he had ever undertaken, so you can understand not getting a perfect 5 the first time But I say again the bungalow finished up as a 5 star It was the journey that let it down slightly Thank you again Argon for all the help before, though and after the project

What to ask a Iver extension builder before hiring?

Before hiring an extension builder in Iver or extension building company in Iver, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

What qualifications and experience do you have as an extension builder in Iver?

An extension builder in Iver should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Iver extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Iver?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Iver extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Iver extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
