hello, my name is Razvan, and I have been working in this field for over 12 years, during all this time I have evolved in masonry from low-level work, from laborer to being a supervisor with a diploma, I have completed many works successfully and I learned a lot about this job from people with a lot of experience behind them, besides this job I also have other skills, such as interior work, painting, laying parquet plastering. at the moment my basic job is bricklaying, I like what I do, and especially making the works look flawless is the most satisfying thing for me, and especially making the customers happy. (contact me with confidence, I promise you won't regret it, you will learn more about me, just by getting to know me and seeing me in action✌🏻)

What to ask a Blackheath extension builder before hiring?

Before hiring an extension builder in Blackheath or extension building company in Blackheath, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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.

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.

Do you offer a guarantee for your work? Most Blackheath extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
