It was a time challenge for me to move to newly purchased house as my rental agreement was due. I got Saby from personal reference. All home colour, wiring, removing old big boiler, water tank and rerouting of all pipe work. Roof repair , new two en suites construction, whole IKEA kitchen. He delivered as per our expectation and design in 8 weeks. No time waste and all material he arranged. I am very happy the way he professionally handled the work and delivered on time. I would recommend him. Make sure your design is ready and perfect. Discuss with him before start and avoid changes for best results.

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 Windlesham extension builder before hiring?

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

An extension builder in Windlesham 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 Windlesham 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 Windlesham?

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 Windlesham extension builder’s ability to deliver a result that meets your expectations.

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 Windlesham 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.
