Decking- 14 Jun 2022
James Hynes of JCH Home Improvements have just refurbished our decking area. We thought it was a straight forward job, just to renew the decking and a tidy up BUT the original wood was so rotted the whole area had to be renewed. Joists, upright timbers etc We are thrilled with what James has done, so much more work than anticipated but the end result is fantastic. Would thoroughly recommend JCH Home Improvements and we will be using the again.

Loft Conversion- 23 Nov 2021
We instructed Masterbuild & Maintenance to undertake a loft conversion and side extension to our bungalow in the spring of 2021. Dan and his team worked tirelessly to ensure that we were happy with every stage of the build and it was never too much for any of them to make modifications to get the desired result. They were hardworking, diligent and genuinely cared about their work which shows in the quality of their workmanship and the various trades employed. Dan’s team worked well together and were on-site every day for the 6 month build. We thoroughly enjoyed working with them on the project and can honestly say that we couldn’t have imagined any other builders doing the work. We are over the moon with the end result and receive so many wonderful comments from people about the job. We would absolutely recommend Dan and his team to undertake any building project and cannot commend their work highly enough.

Extensions- 15 Dec 2021
Valdemar and his team of workers were outstanding. I have never known builders to be so thorough, honest and just generally nice people. They can be trusted and gave honest opinions. They were in tune with the building control requirements and worked very hard always arriving on time and working solidly throughout the day. They may be a bit pricey but you definitely got what you paid for - First class workmen ship.

What to ask a Ongar extension builder before hiring?

Before hiring an extension builder in Ongar or extension building company in Ongar, 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 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.
