Restoration & Refurbishment- 28 Apr 2019
The work included: knocking out part of a wall and creating a new ‘alcove’ area to enlarge one room, removing a door and making good the wall, re-plastering of ceilings and walls, laying new flooring, various electrical works and installation of a new radiator, plus numerous other little bits and pieces. Tony gave me good advice at the planning stage about the various jobs I wanted doing which ended up saving me considerable, unnecessary expense. The price was a fair one and came in on budget. Tony kept me fully informed at all stages. Tony’s team were friendly and helpful. The final result is lovely and well finished. For balance, the only negative was that the job did over run by a few days; however I must add that Tony and his team did their very best to catch up including working weekend days at no extra cost to me. I would not hesitate to use Tony’s services again, and, in fact, fully intend to.

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

An extension builder in Dunmow 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 Dunmow 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 Dunmow?

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

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.
