Roofing (Pitched)- 5 Apr 2024
I recently had the pleasure of working with the A&R company for roof repairs and transformation, and I must say, I couldn't be more impressed. Not only did they do an exceptional job with the repairs and transformation of my roof, but Amar and Jatinder went above and beyond by assisting with other minor fixes. Their friendly demeanor and professionalism made the entire process smooth and stress-free. I highly recommend A&R for their top-notch service and exemplary team members.

Loft Conversion- 22 Mar 2024
Glad we didn't hire him. After agreeing on a price for loft conversion and back extension, Mr Rattan kept increasing the price by referring to minor things. Like charging extra for plate that goes on steel. First day when he turned up, he demanded that owner should provide tea and snack for his labour every day. Also he was not ready to include the agreed price on the contract (as he was sub contracting the job to someone else). Glad we cancelled him and hired another builder in his place. I have evidence of all communication I had with him, incase anyone wants it. I would avoid him at all cost.

Plumbing- 7 Aug 2018
I gave this person the plumbing work for my house extension and renovation for the existing of the house, at first this person was polite and well behaved, after he was given the first instalment, his intentions became clear. The contract, which was signed by both of us, was ignored. it was allegedly written by his 17 years old son, who left them and that the man is not responsible for the contract. Whilst the man and his brother were doing the plumbing a few things which were lying around the house had gone missing, as well as the fact that he had just spontaneously disappeared for two-three weeks at a time on multiple occasions. In each occasion he had brought up excuses such as his wife had a heart attack or he had been to Poland for a bereavement. Towards the end his attitude had changed as he became more aggressive. He had persuaded me to give the last installment and promised to be devoted to the task at hand. As soon as I entrusted him with my hard-earned lump sum from my pension he took his tools and left, resulting in me having to find other tradesmen to do the remainder of the work. In his profile he advertised that he has a diploma and many other qualifications in plumbing, I have my doubts as he could not hold a basic conversation in English. This made me suspect whether he really did receive these “qualifications”. His work had many faults within it which forced me to turn to another plumber.

What to ask a Epsom extension builder before hiring?

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

An extension builder in Epsom 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 Epsom 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 Epsom?

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 Epsom 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 Epsom 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.
