Really happy with the work. Rob has a superb eye for detail and won't cut corners if the aesthetics are likely to suffer. Reliable, turns up when he say he will and regularly checks if happy with works so far, all the way through the project. A really professional and knowledgeable guy. Would thoroughly recommend and wouldn't do so lightly. Will definitely use again when ready for my next project.

Bricklaying- 6 Apr 2018
Not long after Kevin started our work we were hit with some severe weather that halted his work for a couple of weeks, he also hit some supplier issues. However he stuck with us, often commenting that he just wanted the job to look right when finished. Well.... it did look right when it was finished and has drew many positive comments from neighbours and passers by. I would certainly recommend Kevin for similar works.

Extensions- 15 Jan 2025
Finlay did work to a high standard and quality. However, he was repeatedly unable to meet agreed timelines and was much slower than other contractors to complete the work. The project also ended up costing much more than originally quoted. We ended up having to terminate our contract and finish the project with other contractors. This was disappointing as Finlay is a lovely guy.

Extensions- 21 Jan 2018
From the outset we found Ryan to be punctual and polite - at the same time maintaining a good professional balance between friendliness and over-familiarity. The level of detail in his bid far exceeded the other two bids, which got him off to a good start - combined with the fact that he was also the lowest bidder, and a local builder to boot, made him the clear favourite for us. We were not disappointed. Throughout the job, Ryan and his team were very tidy workers, unfailingly good-humoured and always keen to please - nothing was too much trouble for them. In the end, the job did take a bit longer than we had anticipated however the quality of work was first class, and we were totally satisfied. We would not hesitate to employ Ryan again.

I wish to take this opportunity to express my sincere gratitude for the building works you have undertaken on David’s behalf @ 128 This mini project had as you are aware many unforeseen problems commencing at first with the mass pile of broken bricks & foundations which prevented us from just re-installing the wall. I am especially grateful to you for the way we coordinated your works with your other projects to the successful conclusion of this task. I will have no hesitation in employing you again in the future and therefore look forward to working with you again; it was a pleasure working with you, demonstrating a positive “can and will do approach” throughout. In conclusion, please accept my thanks making this project the success it is. AJ

What to ask a Daventry extension builder before hiring?

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

An extension builder in Daventry 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 Daventry 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 Daventry?

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 Daventry 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 Daventry 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.
