Extensions- 15 Aug 2018
100% RECOMMENDED Michelle and her partner measured up and competitively quoted within a short space of time. She was then very patient and supportive when unforeseen planning issues popped up and set the start date back by quite some time. Once building started, all questions were promptly answered by either the site manager or Michelle, both being available at all times. I was away for the duration of most of the job and it was very reassuring to know that I was leaving it all in capable and honest hands. The workers were very proficient and tidied up after themselves at end of each day. They also put in some very long hours at times to hasten the work. I was also impressed by the handling of unexpected problems during the building (mainly invasive tree stumps!). I am absolutely thrilled with the end result. High quality workmanship and a beautiful building which I am sure will last many years. I would certainly recommend them without a doubt.

Painting & Decorating- 3 Sep 2024
Great, reliable contractors. Had a full flat repaint job with some minor repairs (blinds fixing, handle replacement). Claudia was very efficient and responsive in communication. All was arranged pretty quick, appointment attended on time and kept to time schedule agreed. Had done a great job with repaint and provided reasonable rates. Also helped out with few minor repairs so I didn't have to get someone else. Very happy with the service , will certainly hire again. Thank you guys.

Tiling- 21 Jun 2021
Great professional and reliable service from Easy Solution. Waqar called me ASAP and arranged to see my bathroom. He came within 1 hour to see the job and gave me an affordable and good quote. He was available to start work immediately. Waqar also suggested the colour of tiles that would suit the bathroom and made some very good recommendations on where i could purchase them at a decent price. My work was done to a high standards. Tiles are neatly put together with grout and they are looking amazing! I had some many relatives comment on them and i have recommended Waqar to them all as i was so satisfied with his service and professionalism in my property. I will be using him always in future. Thanks.

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

An extension builder in Highgate 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 Highgate?

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

Do you offer a guarantee for your work? Most Highgate 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.
