Extensions- 9 Oct 2020
Ryan and his team built a kitchen extension and installed an en suite bathroom for us. Their quote was competitive compared to others and they completed the work in the original 12 week time frame promised. They were friendly and approachable throughout and happily adapted to our changing plans as the project progressed, making suggestions to help us solve problems that came up. The work has been finished for a few weeks now and we're really pleased with the quality of the finish and have had no teething issues to address. We'd happily use them again for any future projects.

CJ was excellent from start to finish. He’s reliable, punctual, and a true one-man band who took care of everything himself.

Source FM recently helped us fit out a new 8000 sq ft warehouse in Hackney. The project included installing new electricals, installing new fire and security alarms, repairing and repainting a heavily used concrete floor, redecorating, servicing the heating etc. The project had a very tight time frame and Source FM often had to work around members of our team as we started moving in while work was still ongoing. I'm pleased to say, all the work was completed in time and to a very high standard. We've since used Paul and Bill for a number of smaller projects, both at the warehouse and in our offices.

Great job done under difficult circumstances (all through the toughest part of the pandemic). Great follow up/after-care service to make any issues or problems right. Great bunch of people to work with that kept me informed and up-to-date. Didn't ask for huge amounts of money up-front, just as they went along. Would highly recommend.

Carpentry- 12 Apr 2026
I initially hired them to build a stud wall and box in some pipes, and I was really impressed with both their work and attitude. They were professional throughout, turned up on time, and completed everything to a high standard. Communication was very easy—they were clear, responsive, and happy to answer any questions I had. After seeing the quality of the work, I asked them to take on a few additional jobs, such as painting, fitting lights, trimming doors and much more, which they were more than willing to do. They handled the extra tasks efficiently and without any fuss, and everything was completed quickly. Overall, a reliable, skilled, and easy-to-work-with builder. I would definitely recommend them.

Extensions- 28 Sep 2018
Johnny was very nice to deal with. When there were problems they were quick to find ways to rectify them. They started at short notice& finished on time which I was very impressive. We got a no. of quotes,Johnny was middle of the range but with a better level of service than others. Johnny was very open about when things might cost more &gave us the option if we wanted to proceed. A few things to note: -this was our 1st experience of any building work &we should have remembered they are builders, not designers -we both work long hours &so most days didn't see the team to get an update or brief them. This meant a few things were missed or miscommunicated - while most of the team were lovely the electrician used was horrible to deal with. He got very cross about requested changes, didn't deliver everything requested &just did silly things like putting in a light switch with 2buttons where there was only one Light or hanging lights incredibly low when we had given measurements of where we wanted them - we got Johnny's team to build some extra storage for us which on the whole was fine but some things weren't centred or for example the wine rack they built was wonky Overall, it was a good experience and we would recommend them but would suggest be home to oversee the work more than once a week (must be true of any building work!) and get your own electrician. Very happy to talk to people and give references-the house looks great now.

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.

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.
