Windows & Doors (uPVC & Metal)- 28 Jan 2026
Very unhappy with how things went with Angle Construction overall. Poor comms during the transaction was the first red flag - no communication for 2 days the moment money was sent, however afterwards received an apologetic call - parts ordered and arrived in due course. Andrei turned up, and got to work on removing the old gate, but then started shaving down the post without saying anything -we were told after that the posts were not level. Eventually he said the door would need to be cut, which we agreed to. The door and posts were both cut to fit, but massive gap left at the bottom, and only half of the door fittings and no handles were installed! In addition, where the door was cut and the wood shaved made, a lot of mess was left all over the garden furniture and patio floor. Shocked at the lack of care and professionalism. He was clearly agitated and in a rush to leave. We have a working back door, but it looks like a real botched job. Not happy, and I would not recommend.

Extensions- 8 Dec 2021
Me and my wife are very satisfied with Prabbuilders work. What stands out with Prab builders is that they do every task as if they are doing it for their own house and with work they are meticulous and exceptional. What we started with and how our extension looks now is simply amazing and the way they explain about what will look good(Color/ the structure etc ) is commendable as we both were not sure what decision to make, but after completion we are overjoyed to see how excellent it turned out to be now. I would recommend them anytime based on their skill ,eye for detail, being punctual and the hard-work they invest into every task to make sure we are getting the final product the way we dreamt of.

Extension Builder in Harlow
Hello, my name is Henry, I am a 25 year old bricklayer from South east London. I wanted to become a bricklayer after learning of the history behind the bricklaying, particularly Victorian bricklayers. I often look at old buildings and think of what an honor it would be for future generations to look at my work in years to come and be proud of their ancestors' craftmanship, built with care and attention to detail that will have withstood the test of time.

What to ask a Harlow extension builder before hiring?

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

An extension builder in Harlow 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 Harlow 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 Harlow?

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 Harlow 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 Harlow 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.
