Extensions- 28 Sep 2018
Johnny was very nice to deal with. When there were problems they were quick to find ways to rectify them. They started at short notice& finished on time which I was very impressive. We got a no. of quotes,Johnny was middle of the range but with a better level of service than others. Johnny was very open about when things might cost more &gave us the option if we wanted to proceed. A few things to note: -this was our 1st experience of any building work &we should have remembered they are builders, not designers -we both work long hours &so most days didn't see the team to get an update or brief them. This meant a few things were missed or miscommunicated - while most of the team were lovely the electrician used was horrible to deal with. He got very cross about requested changes, didn't deliver everything requested &just did silly things like putting in a light switch with 2buttons where there was only one Light or hanging lights incredibly low when we had given measurements of where we wanted them - we got Johnny's team to build some extra storage for us which on the whole was fine but some things weren't centred or for example the wine rack they built was wonky Overall, it was a good experience and we would recommend them but would suggest be home to oversee the work more than once a week (must be true of any building work!) and get your own electrician. Very happy to talk to people and give references-the house looks great now.

Architecture- 17 Sep 2025
Overall we are happy with the work that has been done, however the whole experience has been soured by the fact that I am still chasing to have the new hot water cylinder properly commissioned almost 2 years after installation meaning I cannot have it serviced and won't be able to claim on the warranty if things go wrong. My home insurance will also not pay out on any damage that may be caused. The other issue is that the two consumer units that were installed have not been labelled so I have no idea which breaker does what, this is a safety concern. My many attempts to contact Mandeep about this have been fruitless, I'm just being ignored.

What to ask a Westerham extension builder before hiring?

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

An extension builder in Westerham 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 Westerham 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 Westerham?

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