Bricklaying- 25 Feb 2021
My Mum is soo pleased with the completed job, Tommy has made good of a previous bad job by somebody that I hired off of this site. He was polite, quick to respond and due to the weather he wouldn’t start the job as it would’ve be in vain. We would thoroughly recommend him to the point my Mum has also booked him to do her front pathway.

Extensions- 23 May 2022
Ceca Developments have done an outstanding work on our side and rear extension project, and we would definitely recommend this company. Firstly, they have offered a really competitive quote for the work and have been very transparent and detailed in regards to how long it will take to complete the project. Sebastjan has been a pleasure to deal with and was very helpful during the project, providing honest and useful recommendations and being available every time we needed anything. All the work has been completed to a very high standard and to the agreed timelines. We did not have to worry about anything during the whole project, which made this a very pleasant experience.

I originally contacted Joe from Orama to fit a new kitchen for me. When he came to give me a quote, I hadn't yet chosen what I wanted. He really took the time to make several recommendations and so I decided to go ahead with him to design my kitchen fully and fit it. The team were so easy to work with and most importantly respectful in my home! Their attention to detail is second to none. He really understood the style I liked in one conversation. The finish is flawless. I highly recommend them!!

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.

What to ask a Upminster extension builder before hiring?

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

An extension builder in Upminster 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 Upminster 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 Upminster?

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 Upminster extension builder’s ability to deliver a result that meets your expectations.
