Bathroom Fitting- 2 May 2024
I have employed DL Construction to install a new kitchen and bathroom. They are still working in my house but so far their attitude towards their task and helpfulness have been exceptional. I can not comment about the final product yet but I am sure everything would be finished to a high standard. Nothing seems to be a problem for Javi. He always says 'yes please' and I think that is his middle name. I couldn't have asked for better. Well done (so far) Javi and everyone in DL Construction.

I wanted a side infill extension, converting a one bed into a 2 bed. The works was undertaken by Coulsdon Builders which took around 8 months. I made several changes throughout the project hence the delay. They were so accommodating and never had an issue and was always happy to cooperate. The cost of build was £120k and we stuck to the budget. I am delighted with the works and am grateful they made my house a home. They were clean and tidy on a building site and always kept me updated on progress. This is one builder that I highly recommend and trust. Great work guys and thank you again!

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.

What to ask a Soho extension builder before hiring?

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

An extension builder in Soho 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 Soho 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 Soho?

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 Soho 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 Soho 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.
