Tiling- 29 Oct 2026
Excellent service from start to finish. The team showed a fantastic work ethic and worked tirelessly to complete the bathroom floor, understanding that we needed the facilities available as soon as possible. All three were extremely polite and professional. They took the time to introduce themselves to my elderly mother and shook her hand, which was a lovely touch and showed genuine respect and courtesy. The quality of the work was excellent, and I wouldn't hesitate to recommend them to others. Thank you for a job very well done.

Bricklaying- 17 Jun 2022
Our brick garden wall was collapsing and I contacted Richard Fitzgerald for a quotation. I'd already had a few quotes from other builders, some of whom had told me I needed work doing that didn't need doing! I found Richard to be trustworthy. He provided a competitive quote. He managed to source bricks that matched the colour of the adjoining wall, gave us a detailed breakdown of the work he would do, and didn't ask for any payment in advance. He built a strong brick wall with a concrete support wall behind. The finished wall is excellent and we are very happy with the work he and his team have done. On finishing the work the premises were left clean and tidy. I am very happy to recommend him.

Extensions- 16 Oct 2019
Not trust worthy, does not follow the contract, he pulled out in middle of my work in house three times. Never finished on time. Promised to come back and finish The fence and the toilet never come back despite numerous phone calls. I have leaking toilets in the wall big pigments of dampness on the wall paper on the wall adjacent to toilet. Promise to do the roof tiles then he said I cannot do it. Fitted the kitchen units wrong and did not connect the sink overflow pipe to the macerate ( leaking water under sink. Flooring tiles not even still have prominent corners . Front driveway is cracked as he promised to dig and put concrete but last minute changed his mind and put only cement and new slaps. Water pipe outside house is leaking . The stairs carpet and the wooden stairs not painted rightly and the carpet is not fixed right it is out. I paid him all the money left only 150 pounds but never come back to paint fence, summer house finishing and loft ladder. Brought materials and his workers and brought bills never saw some of it. Taken some materials in his van and never discussed this issue. Work meant 6 weeks and now 8 months and still not finished. Do not hire him he and his workers are not up to standards. Will love one from builder. Com come and see the unfinished and damaged in my house.

What to ask a The City extension builder before hiring?

Before hiring an extension builder in The City or extension building company in The City, 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 The City?

An extension builder in The City 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 The City 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 The City?

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 The City 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 The City 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.
