Extensions- 16 Mar 2023
Absolutely brilliant work. Managed to fit us in after being let down by someone else. Extremely professional and on time, was very considerate of noise levels considering I work nights. Done the job to perfection and left everywhere tidy once finished. Would highly recommend Shane and most definitely use him again.

Plastering- 11 Nov 2013
Elite plasterer. That's the only way to put it. Richard did an amazing job at our house. The task was executed a perfection we didn't anticipate. His work has impressed any other building professional who came to our house for other tasks. I highly recommend Richard Kirk's services to anyone who is looking for a very high standard work. Beside his plastering skills, Richard is also very easy going and sympathetic professional to work with. My only regret is that he didn't have time to complete other tasks as he was fully booked. We're looking forward to re-hire him again very soon hopefully.

Extensions- 3 Oct 2020
Harpal and his team were polite, reliable and very professional throughout the build. They turned up on time each time and didn’t leave till the job in hand for that day was done and completed. The work was carried out in a professional and tidy manner and I was always kept informed throughout the build. We will be recommending KHINDA Constructions to family and friends.

What to ask a Birmingham extension builder before hiring?

Before hiring an extension builder in Birmingham or extension building company in Birmingham, 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 Birmingham?

An extension builder in Birmingham 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 Birmingham 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 Birmingham?

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 Birmingham 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 Birmingham 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.
