Extensions- 9 Jan 2019
Altun Property stepped into the project very anxiously and positive. The management were very helpful and assist us with the neighbours requirements, as our building is adjacent to a primary school. The project went thoroughly and took some time because it was a big project. Altun Property were very energetic and supportive throughout the work, they didn't object any amendment the project required and extra work needed. We have received several compliments from visitors to our office for the level of work conducted and the quality provided. Commissioning the work to Altun Property helped us heavily as a charity because we were able to save on the overall cost of the work. I would like to express our appreciation for the work conducted and look forward for further work together.

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.

Bathroom Fitting- 6 Mar 2026
What a great team! Muneeb and his team finished the job in time, turned my tired old bathroom into a wonderful new space. Price quoted was half what we were being quoted by others. Muneeb just focused on this job rather than many others who leave the customer waiting whist doing multiple jobs. All materials used are top quality and nothing was too much for him. Muneeb kept variation minimum and agreed details in advance. Thank you Muneeb and team

Akash made sure the job was complete exactly how he said it would be, he provided reliability during the installation of our kitchen and answered all questions very professionally. The builders were well aware of the conversations my mother and I had with Akash and so put our mind at ease. The installation itself was very quick (the tear down was very much completed in a few hours) and installed over the weekend. They were very hygiene aware and set up a cover between the kitchen and the rest of our house and didn’t disrupt our home living. They cleaned up before they were gone to very high standards without us even asking them too, all I’m sure is due to Akash’s excellent organisation skills.

What to ask a Pentonville extension builder before hiring?

What qualifications and experience do you have as an extension builder in Pentonville?

An extension builder in Pentonville 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?

What experience do you have with similar extensions in Pentonville?

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 Pentonville extension builder’s ability to deliver a result that meets your expectations.
