Home Utility Ltd recently carried out a complete renovation of my 4-bedroom house, and the quality of their work is outstanding. From fitting a brand-new kitchen to completely transforming the bathrooms, every aspect of the makeover was handled with great attention to detail. The team was reliable, highly skilled, and managed the entire project seamlessly from start to finish. Finding a contractor that delivers on every promise without hassle is rare, but Home Utility Ltd made the entire process smooth and stress-free. If you are looking for a trustworthy team to handle a major home renovation, I cannot recommend them enough.

Extensions- 17 Jul 2020
Orgert Myrta and his highly skilled team did an exceptional job renovating our Victorian terrace house in under 8 weeks. On meeting Orgert, his warm, friendly and professional manner was reassuring. I immediately thought he was someone I could work with. His initial assessment of our house, he advised on best possible solutions to achieve our aims within budget. He invited me to visit the homes of his recent previous clients & obtain their feedback, which I did. Visiting two clients, they both spoke highly of Orgert & his team, sharing their positive experience and how Orgert has since completed work on their neighbours homes & family members homes too. Judging by the quality of work completed in both client's properties, I knew Orgert was the right builder for me. Responsive & prompt throughout, good communication, providing weekly status updates, even advising on where to source great deals on second fitting items saving us money. To say we are pleased with how well the project has gone & level of workmanship is an understatement! Without hesitation we highly recommend Orgert & his team, who since finishing our house are now doing work on my relatives house. Orgert & his team completed in our home: - Rewiring & new plumbing - Plastering walls & ceiling - Replace old ceilings - Painting & Decorating - Painted exterior front & back - Replaced & repointed brickwork - Installed new kitchen & bathroom - New flooring throughout
The london Loft and Kitchen Company
Rating: 4.5 out of 5
Extension Builder in Harrow
We are a southwest London Based loft and kitchen extension specialist. Our working area is very small with 90% of our jobs in Wandsworth and any work outside this area is never more than a mile or two away. With over 15 years experience in this area we know inside and out how these properties were built so when it comes to structural alterations you couldn't be in safer hands.

Extensions- 16 May 2017
Initially apprehensive about using mybuilder, we found David easy going, clear and concise from the offset. The work carried out was to a high standard and any changes or questions that arose he was all to happy to answer. We found him to be pro-active in his approach, open and honest with how much items cost and sensible when agreeing monthly valuations. Both of us work in the construction industry and it is enjoyable and a breath of fresh air when you get to work with people as straight forward a David. We hope to do work with him again and would be happy to talk with anyone who is considering taking him on for additional work. Many thanks, Rob and Brom

What experience do you have with similar extensions in Harrow?

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