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.

Loft Conversion- 27 May 2020
I hired Mark to build my hip to gable loft conversion and I'm completely blown away with the outcome. I now have a beautiful bedroom with ensuite. From start to finish Mark and his small team have been nothing but hardworking, reliable, professional and trustworthy. Mark communicated everything efficiently and took pride in his work He respected my home, always cleaning up at the end of the day. I can honestly say Mark and his team are exceptional builders. Due to covid-19 the job started to slow down as a result of building merchants being closed, however Mark was still motivated and committed to complete my job and went above and beyond to source materials elsewhere. I would without a doubt reccomend Mark to anyone who wants a professional builder. I'm extremely happy and satisfied with the end product. Best builder I've ever hired!

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.

Loft Conversion- 4 Apr 2018
We cannot praise Johnny and his team enough. They were simply fantastic throughout our project - they have done a beautiful loft conversion, and transformed the rest of the house.. installed two new bathrooms, opened up the downstairs and installed a new kitchen, installed new front and rear doors and bifolds, restored original fireplace, decorated. They are delightful guys to have around, Johny keeps a firm grip of the project and makes sure things don’t get delayed. They are proper craftsmen and real perfectionists. They work hard, they have an eye for detail, they are unfazed by problems, they kept to schedule - you couldn’t ask for more. Johny was around to give advice at any stage we needed, they left things clean and tidy and have a real pride in their work. We would highly recommend Johny to anyone - he’s a great, trustworthy, hardworking and genuine guy who does exactly what he says he will. This was our first major building project but we couldn’t have been in better hands.

Joinery & Cabinet Making- 26 Nov 2024
We appreciated that we could pay using a credit card with this company. They provided nice drawings of the bedroom furniture layout including sliding doors for en-suite bathroom. We had a good communication through emails even though I would prefer to go over the design in person as I think it would be more time efficient. Even though we agreed certain type of drawers during installation we found these were changed to a different design without letting us know in advance. One of the sliding door have screws visible on the side but not on other door and one joint is unsightly but luckily it’s inside the bathroom in the corner. after the installation some of the drawers’ glued side strips started to peel. Luxiva was quick to come to fix this but it spoiled our experience.

Loft Conversion Company in Ongar
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.

Questions to ask local loft conversion companies in Ongar

Choosing the right loft conversion company for your job requires finding someone who understands your home and your goals.

Find out which company can share your vision by asking the following questions:

What experience do you have with loft conversions in Ongar?

A local loft conversion company in Ongar will know the types of properties and building styles common in your area, as well as the planning and building regulations that apply. Ask about similar projects they’ve completed locally.

Are you insured, and do you offer a warranty for your work?

Insurance protects your home during the loft conversion process, while a warranty shows the company’s confidence in the quality and durability of their work.

How do you handle planning permission and building regulations?

Established loft conversion companies in Ongar should understand local planning rules and building regulations. Ask how they’ll manage permissions, inspections, and compliance to avoid delays or legal issues.

What is included in your quote?

Ensure the quote covers all essential aspects of the loft conversion: structural work, windows or skylights, staircases, insulation, labour, and any additional fees. Understanding this upfront prevents unexpected costs later.

Do you manage the project from start to finish?

Some Ongar loft conversion companies offer full project management, coordinating architects, builders, and tradespeople. Others may only handle part of the conversion. Clarifying this early on helps you understand what support to expect.

FAQ: Common questions about loft conversions in Ongar

How long does a loft conversion take?

Typically, a loft conversion can take between 6 and 12 weeks, depending on complexity, planning permissions, and any structural work required. Be sure to discuss the timeline with any potential loft conversion companies in Ongar before agreeing to start the work.

Do I need planning permission for a loft conversion in Ongar?

Many loft conversions fall under permitted development, but some require planning permission, especially if you’re adding a dormer, extending the roof, or living in a listed building. A professional Ongar loft conversion company can advise and handle permissions for you.

Will a loft conversion affect my home insurance?

Yes, you’ll need to update your home insurance to cover the conversion. Inform your provider about structural changes, additional rooms, and any changes to utilities or heating systems.

Can I stay in my home during the loft conversion?

Many loft conversions allow you to remain in your home, though noise and dust are inevitable. Some Ongar loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
