Extensions- 14 Nov 2019
Bogdan himself is extremely knowledgable and his years of experience in industry is clear to see, which makes choosing him great value for money. Before and during the project he offered solutions that we hadn't considered and the would in fact save us money and be of benefit to us in the future. His team is punctual, reliable, diligent, speedy and clean! They take pride in their work which has led to a highly satisfactory work in the final build. Bogdan also has great connections to third parties (e.g. to flooring and curtains/blinds providers) which is very valuable, especially when trying to coordinate different aspects and timings of a full house redecoration. His quotes and payment structures are fair, clear and concise which is also very helpful. His communication is excellent too. All in all, Bogdan's great work took away a huge amount of stress during these projects. I would highly recommend Bogdan and his team for any prospective works someone is considering.

We renovate, decorate and repurpose buildings to make sure they fully meet your needs. By regularly working with homeowners and landlords, we ensure your property renovation is completed to the high standards you’d expect and is exactly what you need it to be. Having worked in renovations for many years, we understand that it’s not about the amount of work you require. It’s about taking ownership of the space, making it yours and building it up around your requirements and expectations, so you can do exactly what you want with the building. We can redevelop and remodel a space so you can start afresh, or provide a more cosmetic refurb to give your property a new look. Our flexible approach allows us to take on refurbishment projects of all sizes and do every building justice. Regards

What to ask a Blackheath extension builder before hiring?

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

An extension builder in Blackheath 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.

Will my home extension meet all building regulations and planning requirements?

Your Blackheath extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Blackheath?

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