I have employed Jordan Wade many times to work on my properties, his primary trade is a fully qualified carpenter, though any other activity such as plaster boarding and kitchen installations that he has carried out for me has been of top quality.

Extensions- 10 Jan 2017
I couldn't be more happy with the porch that Dave & James built for me. I have a character property and had a very specific idea of what I wanted and they got it spot on. They were extremely sympathetic to the original cottage and my new addition looks like it has been there forever. I decided to go with an Oak front door which James fitted and it's perfect. I was very pleased to see both Dave and James turn up each morning before I headed off for work so that we could have a catch up. I really, really appreciated this gesture. The work was completed on time as promised. I will most definitely be using David James Construction in the future with the landscaping of my front garden being the next project. I am so pleased to have found reliable, skilled and trustworthy tradesmen who I know I will go back to time and time again. Thank you ever so much Dave & James!

What to ask a Olney extension builder before hiring?

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

An extension builder in Olney 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 Olney 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 Olney?

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 Olney 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 Olney 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.
