Extension Builder in Thatcham
Your house is your biggest investment you have and it an honour that you choose me to work on your investment. Hi, I'm Phil Baker and I've been in the building trade all my working life, 40 plus years. We try carry out only 1 job at a time, being there every day, every week, from start to finish. It's this "dedication " to just your job that stands us out from the other. To complement that dedication is our main tools in our arsenal !! Namely hoovers, dust extractors and dust sheets, the key thing to remember here is that after all, it's still your house and home and not a building site. After we have gone home it's still the place you have to eat and sleep, so it needs to be respected so. It needs to be as clean and tidy as possible !, so you can still function as a family safely. Many jobs we have been appointed over the years have come from prospective clients noticing how tidy the outside looks ! Tidy, neatly stacked skips, materials maintained neatly and covered over. After all, these are the materials you are paying for so need to be protected properly outside until used. A happy and good site gives you the best job results. Philip Baker.

Radu was excellent. The price was honest and fair, and I was kept informed when there was a slight delay. The job was a simple repointing repair, and Radu and the team got straight to work with no issues or need for explanation. The result was great, and I would happily hire Radu again.

We hired Belle Partnership for a two storey extension and remodel of our home. The project included structural work (knocking through and installing steel beams), building the extension shell, roofing, new windows and doors, first and second fix electrics, plumbing and plastering. Communication was clear and professional from the start with any variations - either at our request or where small snags were encountered, which was inevitable on a project of this size - discussed and priced transparently before work proceeded which helped us keep control of the budget. The team were punctual and generally kept to the agreed programme. There were a few delays due to material lead times and weather, but these were communicated in advance and didn’t feel avoidable. We were kept informed of progress throughout, which made the process less stressful. Tidiness on site was good with the team keeping the working areas as organised as possible and cleared away debris regularly. We're very happy with the workmanship, the work being finished to a high standard. This was a significant undertaking for us and Belle Partnership helped us achieve what we wanted. Chris and his team were professional, approachable, and capable of delivering a substantial extension and remodel to a good standard. I don't think any project of this scale is entirely without minor issues but we felt they dealt with challenges responsibly and delivered what was agreed. We would recommend them to other homeowners considering a similar project.

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.
