Extension Builder in Longfield
I have over 15 years experience working on the tools. I started building work with my Dad when I was still in school and joined him professionally when I was 19, I am now 37. I started on suspended ceilings and plaster boarding walls and ceilings. Then I moved into more residential works doing extensions and refurbishments. I have a good team of guys around me that between us we can get any job done for you. Customer satisfaction is very important because you are as good as your last job!

Extensions- 24 Jan 2021
We chose Gibbons and Sons for our Loft extension and new bathroom as they was one of the few firms who we contacted and was more then happy for us to view their workmanship during and after the build so we good see the quality of their works. They have been courteous, polite, very patient and accommodating to our chopping and changing of ideas. They helped us to bring our visions to life and offered advice when required without being pushy and driving a hard sale. They have been open and honest with our ideas and their recommendations and in some cases suggested a alternative more cost effective option. All in all we would highly recommend Gibbons and Sons for all types of building works.

Loft Conversion- 5 Dec 2018
Firstly the date of job posting and date of completing is all down to me not being ready with finances!! Secondly, and more importantly, GG Property were the most wonderful and professional bunch of lads you can hope to met. The work was done with such enthusiasm and to such a high level of detail. We could not be happier with the finished job. Thirdly, the great building work aside, GG Property were polite, happy, friendly, punctual and great communicators. All emails answered swiftly and with accurate information. No question was to silly and no concern (this was our first major building working) was to small to be addressed. Finally we are so pleased with work we are awaiting a quote for our bathroom and look forward to getting that job completed!! In short my experience with GG Property was nothing but top quality work and customer service. Any fears of the classic 'cowboy builder' could not be further from the truth; GG Property are a hard working truly lovely bunch and we would highly recommend them.

Conversions - General- 20 Jan 2019
Lee of LC Builders did a fantastic job from start to finish. He not only did a great job on my building job, he also helped with a structural survey and with paperwork. He could not have been more helpful. His work and efforts have helped us in the selling of our house; without Lee's work and help we would not have got the job done. I would recommend Lee and his team without hesitation.

What to ask a Longfield extension builder before hiring?

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

An extension builder in Longfield 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 Longfield 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 Longfield?

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 Longfield 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 Longfield 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.
