This was a whole house refurbishment involving a garage conversion to an office and a utility room and a doorway through to the main room. The whole of the downstairs was opened up removing walls and replacing with steel girders. This required further footings to be installed and vertical and cross beams to support the structure. Also removed a door and windows to install bi-folding doors. All then plastered and made good. Cavell employs a team of very friendly, happy and accommodating tradesmen and his overall aim is to make sure the customer is happy with the end result. He was also very accommodating and helpful when problems arose. I have since employed Cavell to do a whole refurbishment of a rental flat and several other minor works and repairs. We are now embarking on another whole house refurbishment which will involve a two storey extension and walls to be removed and steels installed. I would have no hesitation in recommending Orange Tree Construction.

Bricklaying- 28 Feb 2021
Brilliant job by Craig - he had to correct poor work done by my previous builder, and i wish i had hired Craig straightaway........ work was done to a superb standard, and all finished very neatly, and measured properly so windows and doors fitted as they should. All mess was cleared up and left tidy, and they even left my mixer cleaner than when they arrived. Would certainly recommend, and will get them back if i need anymore brickwork, groundwork, patio, drive etc doing. Keep up the good work!!

Very professional, with great communication and finished all works to a high standard within the estimated time, accommodating all changes as the works went.

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.

Extensions- 18 Sep 2019
To start off with the job went reasonably well - we were happy with the workers and the progress. but when we neared completion the work slowed up we waited 3 months for a response from Jordan. we had an issue where his plasterer hid the plumbing access in the wall. - This cost us £500 to sort and re-decorate so we came to an agreement that this was fine and at the time i presumed that Jordan was going to sort out the building control. so we then chased and chased but obviously since he had his money he wasn't interested he answered the phone and hung up. so we called building control and there are 2 small bits to fix which are all due to his work not being up to scratch. obviously i will be paying out for this - so please be careful when using him and dont pay him until you have all of the documents as he will not resolve any issues after being paid. i have had 2 previous building projects and this was by far the worst experience going. avoid dont use him thanks

Loft Conversion- 20 Jan 2026
I have chosen Byron and his company to complete my loft conversion. Job was completed within given time frame. Byron and the team were polite and hard working. During the building time, any issues found by myself were addressed and rectified as much as possible. At the closing weeks of my project, I have asked Byron to complete additional carpentry tasks. He found the time to accommodate my requests. Job had some messy stages but Byron was always trying to leave site clean as much as it was reasonably possible. Thank you for your work and I would be happy to hire you again in the future.

What to ask a Halstead extension builder before hiring?

Before hiring an extension builder in Halstead or extension building company in Halstead, 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 Halstead?

An extension builder in Halstead 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 Halstead 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 Halstead?

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 Halstead 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 Halstead 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.
