George designed, built, installed a set of custom-made doors for under my stairwell. Lovely guy, very courteous and pleasant to have around, and the work was precise and pleasing.

I was very pleased with this company so much so that they are starting a new job for me November 15. The building firms carried out a full loft conversion for me installing bathroom, brickwork, joinery, plastering, Roofing and installation of windows and double glazed doors. I have high standards and want everything to be completed in the same way, the workmen respected my home and always left if clean. My main contact was with the owner of the company Dwight Lynch, he was very flexible and Nothing was too much for him to do. He has an attitude which I like in a builder "customer not always right but must be happy" he provided me with ideas along the way and where things did not go to plan due to my own instructions he worked around the issue and provided suitable alternative options. I was very happy with the pricing of the job and feel that certainly I would recommend him and also I would use him again. He and his workmen were all trust worthy and I gave them keys to my house to carry-out work whilst I went on holiday. I had no concerns when I came back everything was as I left it.

Extensions- 13 Nov 2019
Mark managed the whole job (which was complex and involved three different rooms; change of use and new build) effectively and efficiently and engaged family members and friends in various trades as needed. With extensive experience Mark was able to make suggestions and put forward many ideas to improve the basic plans that we had which was most helpful. This included raising a ceiling level to a better height than we had envisaged possible and removing the need for a pier so that a wall could be flat throughout the new kitchen. Mark has a good eye for the aesthetics of a job. He is also very amenable to adding on extra smaller jobs in the process and even procuring some materials that I wanted in order to do something myself ! The workmanship and finish is high quality for a competitive price. I would not hesitate to recommend Mark and have, in fact, already done so for another couple of potential jobs. Finally, Mark is a really nice guy and great to have a chat and cup of tea with (two sugars!)

What to ask a Crawley extension builder before hiring?

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

An extension builder in Crawley 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 Crawley 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 Crawley?

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 Crawley 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 Crawley 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.
