Building Contractors in London

If you have decided you need the builders for a construction project in your home it can be daunting trying to decide which building contractors should carry out this project. After all, it is a large investment that you are ready to pay out for so you want to choose the best building company in London that you can.

What Defines A Good Building Contractor?

There are thousands of building companies across London, but not all will provide the same service.

To identify the best building contractors in London you will want the ones that are highly experienced, with qualified tradesmen that deliver high quality results each and every time in a safe environment and deliver the project on time and within budget. A building contractor that always puts their customers first and has returning clients again and again.

You will often hear building companies say they can do anything. This is dangerous. You want a building contractor that is right for your project. For example, at Jeffery and Wilkes if you came to us and asked us to build you a brick wall or a add a toilet to your downstairs we would likely refuse the work. Why? That is not our niche, we take on larger projects like full refurbishments, house extensions, loft conversions etc. It would not be beneficial for us or you to carry out a small project like that. However, there are some builders in London that are fantastic with small jobs like this and really will step up to the task and excel. So when you are speaking to the various builders find out what type of projects they specialise in and what size projects is their niche.

Building contractors in London will vary in the services they offer or more importantly are good at. Some building contractors specialise in residential construction, perhaps in loft conversions, extensions, refurbishments, whilst others are better with smaller projects like bathrooms. Then there are the building contractors that are experts in the commercial sector and building office spaces and fit-outs etc.
