Extensions- 27 Oct 2022
Jack and all of his team were great from start to finish. Having never had any building work like this done Jackbwas reassuring, punctual and always happy to answer questions. Any issues were communicated promptly and solutions discussed. All of the team were really mindful of keeping mess to a minimum, and always tidied up at the end of each day. Jack also worked directly with building control to help smooth the sign off process. All in all I can't recommend Jack highly enough for anyone looking for a reliable and quality construction job

Extensions- 8 Oct 2025
Jason and his team have just completed our wraparound extension, and the result has exceeded all expectations. Their workmanship, accuracy, and attention to detail are outstanding, and the whole process was smooth and stress-free. They stuck to timings, kept the budget in mind, and made everything feel effortless. Partway through the build, Jason had to undergo an operation and was signed off for five weeks. Remarkably, nothing was delayed — his team carried the project seamlessly, and with Jason still on site when he was able to be, everything ran perfectly. It’s a real credit to how capable they all are and the consistently high standards they work to. The only negative thing I can say is that we were sad to see them leave – they’ve been such a positive part of our daily lives over the past eight weeks. The finish is exceptional and we’re absolutely over the moon. We couldn’t recommend Jason and his team highly enough.

Lorant and his team, recently completed a multi-room, multi-level extension and a utility room for us, and we’re very pleased with the work. The build is of good quality, his team was professional, always well-equipped, and if you’re clear with your instructions they will follow them well and execute to a high standard. He managed to finish the project despite tough conditions, like the heavy rain in January. This is the second time we’ve worked with him—he did an extension for us ten years ago, and that’s why we brought him back. We’d always recommend him for the value and build quality. Lorant offers experienced advice and different options to consider during the build. Once Lorant agrees on a quote, he’s fair and doesn’t try to add extra costs. His communication is great, if you send him a message, he usually replies within minutes or even seconds. Highly recommended,

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.
