Latest review:
Last summer we unfortunately had a house fire which was deemed uninhabitable by the fire brigade. 4 adults, 4 vehicles and 2 dogs needed rehoming, and this was an incredibly stressful time. The insurance provided advice and got teams in to deal with the contents and provided a schedule of works that would need to be completed in order to make our home habitable again. We had heard stories about insurance companies taking a very long time to complete work due to the logistics of getting separate trades to come in and deal with every step individually. We began to look into the option of a settlement with the insurance company and obtained some quotes from builders to deal with the project from start to finish. We just wanted to get back into our own property as soon as possible. We looked into a couple of companies who were over our budget to our settlement figure. We contacted BPM Builders through word of mouth, which is run by two brothers and a nephew. What a team! They were knowledgeable from the start, showing great expertise in the world of building inspectors (due to some internal structural damage) and organized all of that for each stage. They were able to quote for the whole package including ripping out and disposing of smoke damaged ceilings, floorings, well everything really). Quickly getting the property ready to rebuild. They have the knowledge of all trades, from ceilings to floorboards, insulation, new windows, new stairs, all the first fix plumbing and electrics, plastering, tiling, bathroom and kitchen fitting. They were able to provide excellent advice from the structural issues down to where we wanted the light switches/plug sockets. They were so empathetic around our situation of the fire and made the whole experience easier, as well as their friendly manner made them very approachable, even when I changed my mind over things! I would highly recommend and have passed their details to friends and family.

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.
