Extensions- 9 Jan 2019
Altun Property stepped into the project very anxiously and positive. The management were very helpful and assist us with the neighbours requirements, as our building is adjacent to a primary school. The project went thoroughly and took some time because it was a big project. Altun Property were very energetic and supportive throughout the work, they didn't object any amendment the project required and extra work needed. We have received several compliments from visitors to our office for the level of work conducted and the quality provided. Commissioning the work to Altun Property helped us heavily as a charity because we were able to save on the overall cost of the work. I would like to express our appreciation for the work conducted and look forward for further work together.

Bricklaying- 9 Aug 2026
Agron was absolutely brilliant. We agreed a price at the end of May however we couldnt go ahead in June (our issue) and Agron was very accommodating. We reached out in July and he fitted us inbetween his other jobs. Each day he came he started at 8:30 and worked till past 6pm. He was always active and we had to encourage a break. He always kept us informed of any changes and issues along the way and at the end we got him to do a few extra bits while he was with us. Overall he did a fantastic job of building a new wall, laying floor tiles. Will highly recommend Agron and i will definitely be using him again for any brick work in the future.

What to ask a Ongar extension builder before hiring?

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

An extension builder in Ongar 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 Ongar 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 Ongar?

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 Ongar 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 Ongar 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.
