Extensions- 24 Oct 2019
From the first visit when they came to do a site overview to produce the quote they had warned me that there could be some unknowns once we demolish the existing lean-to as there were no registry or plans for how the sewage/water pipes went under the house. Other than the groundwork adaptations which incurred a bit of a cost increase Rowan's quote was adhered to to the penny, in fact, to get the foundations to not interfere with the pipes, my extension ended up being a couple feet bigger and this was not charged extra by Rowan. Scheduling wise, The demolition and extension rebuild to first fix was scheduled for 5 weeks, but I was so impressed with the work i decided to extend the contract all the way to second fix/finished extension - including decorations, all in all the whole project took about 8 weeks, which considering I kept them on till the decorating was finished is inline with the original schedule. I would like to particularly thank the guys who spent the longest on my site: James and Simon as they were very patient and informative and had to put up with my dog disturbing them the most, but also thank to Graeme, Cossie, Scarfy, Mick, Dave and John for all the work they did, and to Mike and David for coordinating the whole project. i would recommend Rowan to anyone that is looking for a 'one stop firm' to do a whole project without having any stress of managing it yourself, and most of all at a good price!

What to ask a Oxfordshire extension builder before hiring?

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

An extension builder in Oxfordshire 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 Oxfordshire 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 Oxfordshire?

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 Oxfordshire 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 Oxfordshire 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.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
