Benjamin and his team did a fantastic job on my property building a 6m by 6m Extension walls in only 2 days, it was done ahead of time and on budget. He was very conscientious and nothing was to much trouble. Done all the pictures of each step along the way needed for Building Control Guy. The quality and workmanship was first class and I would definitely recommend him for all types of building/refurbishment work.”

Painting & Decorating- 27 Apr 2018
Claudiu and his team did an excellent job renovating our 2 bed flat in Bushey. He did a great job on the laminate flooring in particular. Installed coving, skirting, painted walls/doors/radiators, installed new light fixtures, and assembled furniture. Will definitely work with him again. In fact, I hired him back to do our bathroom next week!

Bathroom Fitting- 15 Nov 2017
Mario was an absolute gem from start to finish. After a leak left our only bathroom out of action Mario came in and managed the full project to perfection (and also had a great tiler and electrician who did some other works). Six months on and I cannot fault any of the works. Highly recommended.

Our driveway spotlight sensor stopped working - replacement spotlights, new stronger cable fitted, replacement driveway wall mount lights, disability ramp made and driveway washed. pretty straight forward. Sam bought the correct lights, extended cable and the sensor with his electrician from B&Q. Removed and replaced removed all the rubbish, respected our property gave the driveway a wash no hassle - left them to do their work and it was done. I would recommend using them they do what you want and how you want it - He does give you his opinion though up to you if you want to take it or not. happy to use them for further jobs

Hard Flooring- 7 Nov 2017
I hired Alin to install laminate flooring within a quick time frame. Alin was quick at replying and scheduling in a date. He gave good advice to suit our needs and worked fast and efficient. He has always been professional at my home. Alin got all the work done within one day which I was delighted with. We are very happy and confident in him so we have hired him back to do many other jobs in our home.

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.
