Handyman- 7 Sep 2024
Lovely young man Sim very polite, professional and respectful in my home. He completed the job to my expectations, putting up some curtain poles and assembling a chest of drawers.

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.

Extensions- 20 Feb 2020
Decent builders but with extremely poor communication skills. First the good points: 1. They are good at internal finishes 2. They create and use a Statement of Work (SOW) to track all costs of the project, so there were no major surprises in the project 3. They are friendly and hard workers - who arrive on time Gotbath UK Ltd used subcontractors to build us a 6 meter rear extension. Although they had an in-house architect, they did not know the law around boundaries which resulted in a conflict with our neighbours. After spending hundreds on hiring a boundary surveyor, the initial wall had to be re-built within our boundary. Gotbath did not take any responsibility for the wrong information they provided to us regarding boundaries and charged us for the rebuild. When discussing how to finish the inside of the extension, GotBath were extremely slow in ordering supplies and in general responding to us, so we took matters into our own hands and ordered materials ourselves which were removed from the SOW provided to us. At the end of the project, finishes took a long time and required constant chasing. Final gas, electrical and warranty documents took a long time to reach us and required a lot of chasing too. I have very little confidence that GotBath will honour the warranty document they have provided to us. It's a shame because I can see GotBath have a lot of potential as a builder. However, their lack of communication has really let them down.

Great job from Mateusz and his team! They did great job in our kitchen. Tiling,2 splashbacks and cooker hood were all installed within one day and that includes them cleaning the place. Guys turned up at 8am sharp as agreed and did not stop until everything was done. We're very pleased with the quality of works as well. If IQ home improvements are not the cheapest, they are definitely one of the best.

Plastering- 13 Jun 2020
Andi and his team were amazing. They removed the existing plasterboard ceiling and replaced it then plastered the walls and ceiling. His price was very reasonable and job was done to a very high standard. His team were very friendly and their work was clean. Andi even went out his way to help me pick up a few heavy items from shops and load it in his van. Cannot fault his work and finished work on the time scale given. Recommend to all. Thanks to Andi and his team for giving my house a fresh look.

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.

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.
