Conservatories- 7 Jul 2026
Darren identified the problem with my conservatory leak. Fitted a new, larger drainage pipe, repaired a gap he’d spotted on the tiled roof abutting the conservatory. It hasn’t rained since the work was completed but I’m hopeful all will be well. I wouldn’t hesitate to use Coastal Renovations in the future.

CAD / Drawings- 23 Sep 2020
Marius has been doing a great job and put in an extra effort to ensure we were happy with the outcome. I can not recommend Marius highly enough, especially as he managed to fix an issue with the council that we had from someone else drawings. He was patient and very well prepared. Went an extra mile and gave us different ideas/options. He was flexible with timings and most importantly with price. Had by far the best quote and did an exceptional job.

We recently completed a first and second floor renovation alongside an 5x6m extension of our 1930s property with Maxcontractorsint.ltd , and we couldn’t be happier with the results. From start to finish, they have been absolutely fantastic. The attention to detail and the quality of workmanship throughout the project has been exceptional. Matt and his team are incredible, they worked efficiently, kept work on track, and made sure we were updated and involved at every stage. Their skills, ideas, and collaborative approach truly brought the whole project together. Communication throughout the project was good, and the team provided great pre and post project support. Matt was very detail-oriented, offered inspiration during site visits, and was supportive of our requests along the way. We’re so happy with the end result and would absolutely recommend Maxcontractorsint.ltd for any project.

Restoration & Refurbishment- 12 Jun 2026
Hired to finish off a complete flat renovation - work mainly consisted of painting, some remedial repair work, light carpentry and a snagging list. Whilst Raj and his guy were great at light repairs, handyman and carpentry work (which is the only reason I’m even rating them with stars), their attention to detail and completion of the snagging list was very poor! Despite having discussions with me to rectify things after I showed him examples, the flat is now left with uneven paint edges, drip marks, uneven grouting, unpainted architraves and sloppy silicone work. Whilst they are good at some things, decorating is definitely not one of them, so it’s a shame and disappointing.

I've used Facundo's team to install a new shower, including wall and floor tiling, massage jets, and concealed shower equipment. Facundo was the person we dealt with at all times, although someone else was assigned to do the job. The quality of the work and finish is extremely good. I was also impressed with Facundo's professional attitude at all times, being very polite and respectful, as well as proactive in addressing any potential issues affecting our planning and execution. Highly recommended.

What to ask a Chinatown extension builder before hiring?

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

An extension builder in Chinatown 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 Chinatown 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 Chinatown?

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 Chinatown 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 Chinatown 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.
