Carpentry- 29 Jan 2025
Chris had great ideas about how to tackle the job (without being pushy), suggesting that we took the opportunity to include some underfloor insulation at the same time as fixing the floorboards. He scheduled the work at a time that was convenient for us and got it done with a minimum of fuss and disruption. The result is very impressive... no more squeaks or movement and warmer and less drafts too. We will definitely give Chris a call for any other building projects.

Worst mistake I've made in a long time. Poor quality workmanship, poor communication, poor project management and took way over the allocated time to finish off.

Restoration & Refurbishment- 6 Jan 2023
Delighted with the refurbishment of the flat. Great communication, very flexible and helpful, and really high standard of work. Stefan also made some very helpful suggestions during the planning stages that improved the overall end result. Everything was very professional and on time, and we felt that the refurbishment was in very capable hands. This was not the cheapest quote we were offered but it was competitive. It was certainly the highest quality and most comprehensive quote we received, and everything stayed within budget. We were not living in the flat for the majority of the time it was being refurbished, but all the workers we met on our brief visits were great, and it was beautifully clean when we went to do the final handover. Overall, our experience was extremely positive and we wouldn't hesitate to recommend this builder.

CRAWFORD CONSTRUCTION TUTUM TE ROBORE REDDAM ~ SAFETY THROUGH STRENGTH Crawford Construction is an established building firm with a long history in construction. We believe that strong communication is the key to any successful project. For this reason it was clear to us that having a local ‘high street’ office space, which our clients could walk into at any time, would not only be reassuring for our clients but also ensure the smooth running of each project. Since the opening of our Head Office on Walton Street, Oxford at the beginning of 2017 this has certainly proved to be the case. 2018 saw further expansion of the company, carrying out work in Kensington, London. Without doubt Crawford Construction benefits from the extensive knowledge, experience and reliability of our staff. The strength of our team both in our office and on site ensures that the service we offer is consistent and dependable. Our portfolio boasts some of Oxford and London’s finest addresses and includes a variety of projects from complex new builds and listed buildings to large basement projects.

Carpentry- 11 May 2021
Paul quoted a fixed price to clad a large wooden building with Larch tongue and groove boards, the care and attention to detail he brought to the job was absolutely extraordinary. Paul finished the job on time, minimising waste and his professional finish has transformed the building. Paul worked together with his Father several of the days and both were a pleasure to have at our property, 10 out of 10.

Bathroom Fitting- 7 Dec 2021
We hired Shaun following accepting his quote and start date. Unfortunately start date was replanned (ok, things happen), but then communication ended (no return of calls/messages) and I've not had any further feedback. I cannot comment on workmanship as no work was done, however our experience with this trader was disappointing. We are back at square 1 finding a bathroom/boiler specialist and have lost multiple months.

I myself have 18 years experience in building. This is an old profile I set up a few years ago but didn’t really use. I’ve been working on building sites for big companies again the last few years but have recently set up on my own again. Please give me the opportunity to show my skills. My first few jobs I will be looking for the rating not a pay day so please give an honest rating and if your not happy with any work please give me the opportunity to fix before any review.

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.
