We honestly can’t thank the team enough for everything they’ve done. From the very first day to the final handover, they have been incredibly professional, knowledgeable, helpful and so patient. They always took the time to answer our questions, offer advice and make sure we were completely happy every step of the way. Building work can be stressful and unexpected challenges are inevitable, but every obstacle was met with a smile and a solution. No problem was ever too big or too small, and nothing ever seemed like too much trouble. Their experience and attention to detail gave us complete confidence throughout the project. The quality of the workmanship is outstanding, and it’s clear they take enormous pride in what they do. They treated our home with respect, kept us informed throughout, and genuinely cared about delivering the very best result rather than simply finishing the job. They haven’t just built an extension and renovated our home—they’ve created a space that our family will enjoy for many years to come. We are absolutely delighted with the finished result, and it has exceeded everything we hoped for. If you’re looking for builders who are trustworthy, reliable, highly skilled and genuinely care about their customers, we couldn’t recommend them more highly. Thank you for making our dream home a reality.

Kitchen Fitting- 3 Oct 2026
After being let down by two previous “painters and decorators”, I was dubious about hiring Alex based on some of his reviews. I couldn’t have been more wrong! Alex is an absolute lifesaver and a godsend. After speaking over the phone and reviewing the job the following day, Alex and his lovely dad, Peter, completed my flat-pack kitchen fit-out in just three days! From day one I was blown away by their professionalism, efficiency and work ethic. Alex listened to my requirements and concerns, was incredibly understanding, and genuinely cared about doing the job properly. His work ethic is something you rarely see these days from my experience. There's still plenty to do around the house and I'll be calling Alex when I’m ready for the next stage. I wouldn’t hesitate to recommend him. I’m thrilled with the work so far. Thank you Alex, for being so hardworking, reliable and understanding, especially after the time, money and stress I’d lost with previous contractors. ⭐️⭐️⭐️⭐️⭐

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

An extension builder in Sidcup 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.

What experience do you have with similar extensions in Sidcup?

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

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.
