Hi I’m Mark I started my own company around 10 years ago after years of working for other people. Starting trade was plastering which is still my favourite trade and what I love to do. I have done some commercial work but mainly domestic. My company has grown over the years and taken on lots of projects from a 200 year old listed building converting it from a pub to restaurant to Modern day homes. We undertake any works from plastering a single wall to extensions, refurbishments, kitchens, bathrooms and everything in between. I like to work close with my customers for that personal touch in making your vision/dreams come to reality. We are always looking at new products on the market which helps give the best results for your projects and can save time and cost which helps to stay relevant and competitive. I work close with a great architect and have a large knowledge and understanding of drawings and structural design so if you’re just starting your journey we can take care of it all from start to finish. So what ever your project let us make that vision come true.

Kitchen Fitting- 26 May 2021
Obtained a few quotes for two jobs - install new kitchen and new bathroom. Steve was not the cheapest but it’s not all about price. He was the most thorough whilst quoting and had a genuine interest in the job and made some extremely useful suggestions. The work is now in progress and I am so pleased we went with Steve. Really couldn’t ask for more - constant updates and work being carried out efficiently. I have several properties that are rented out and in future I look forward to working with Steve. Thank you.

Landscaping- 28 Jul 2026
Luke just completed our garden transformation. Absolute pleasure working with them from start to finish. Brought the vision to life, very helpful and accommodating. The team have a great eye for detail, very meticulous and professional, and at reasonable price point. We have two young children and they kept their work spaces safe and tidy with such minimal disruption and left everything spotless. Luke is very transparent and professional, communication and timing were always spot on. Not only have they done such a great job and created a really beautiful space for the family to enjoy, they also made the whole process entirely stress free and seamless. Could not recommend them enough

Renaldo and his partner completed a garage conversion at my house. I obtained 3 quotes and they were reasonable. Turned up on time and kept me informed with the works on a daily basis. Really liked the work they did and even when I made small changes they were more than happy to help. Any queries from Building Control were answered efficiently. Cleared up all the mess when the job was completed. I will definitely be using them for any future projects.

Bathroom Fitting- 9 Feb 2019
Extremely pleased with the job Remi did. At the quoting stage he was upfront about costs we might not have considered, but still ended up being very competitive on price. During the job, he communicated clearly when he came up against issues; his fitting was to a high standard; he was on time and worked as long as he needed to each day to finish the job. His after-care was also good, as he returned to fix a related issue that arose during the work without quibbling; he also came back to complete fitting an item whose delivery had been delayed. Overall, I'd definitely hire him again.

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.
