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.

Restoration & Refurbishment- 25 Sep 2025
We were over the moon with our kitchen once Zihni and his team had finished. We had never used this firm before but we will definitely be using them again for future projects. Zihni is calm, knowledgeable, and went over and beyond in helping us not just complete our kitchen project, but in helping us move into a new home smoothly. We are also really appreciative of the rest of his team, as they were all so serious, professional and perfectionists. Zihni's communication was probably the single reason why the completion of our kitchen was such a success.

Plastering- 4 Aug 2026
James was easy to speak to and took the time to answer all of my questions while we finalised the scope of work and contract. His quotation was fair and competitive. The work included replacing the felt on the side extension and dormer flat roofs, as well as applying a silicone render to our Mock Tudor house, all of which was completed to a very high standard. The roof tile repointing, valley leadwork, fascia and gutter repairs were carried out thoroughly, and the roof now looks neat and tidy. A few small items that had been missed from the original contract, but James was happy to take care of them without any issues. James was professional, courteous, and reliable throughout, providing a hassle-free experience from start to finish. His team did an excellent job, kept the site clean and tidy, and completed the work with great attention to detail. I would be more than happy to recommend Ridgewell Roofing & Building Ltd. to anyone looking for high-quality roofing & rendering work.

What to ask a Aldersgate extension builder before hiring?

What qualifications and experience do you have as an extension builder in Aldersgate?

An extension builder in Aldersgate 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 Aldersgate 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 Aldersgate?

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 Aldersgate 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 Aldersgate 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.
