Restoration & Refurbishment- 26 Mar 2023
Well what can I say.... Maciej has absolutely been MAGIC! Always has a smile on his face. He knows his stuff and will go the extra mile. Takes care of everything giving you peace of mind. Trustable guy. Ripped out full kitchen, all electrics done with fittings, plastered and painted in between other jobs. Gives you loads of ideas. I really can't fault him. He's been accommodating. Always on time and makes sure everything is clean and tidy before he leaves for the day. He will be completing underfloor heating with full laminate once the kitchen goes in. I definitely recommend him to anyone. I know he will have all my future jobs that's for sure. Thanks Maciej 🙂

Painting & Decorating- 10 Jul 2026
We have just moved from Australia into a new house. There is a lot that needs doing. The team were great! I asked them to do considerably more than they were expecting to do. I certainly moved the goal posts several times. Nothing was too much trouble! They were very helpful. Thank you for all your hard work.

Extensions- 14 May 2019
We engaged Civenco following a three way quote in which they were clearly competitive. What impressed us most was the professionalism and approachability of John and his team. When it came to the job itself they were timely, very competent and helpful throughout. They rectified minor snags quickly and were a pleasure to work with. I have no hesitation in recommending them.

Extension Builder in Blackburn
I started Bricklaying in 1996 for Barratt Homes where I attended college for 3 years. In that time I won the apprentice of the year 3 times and attended 2 bricklaying competitions finishing 4th and 2nd. In 1997 I won the apprentice of the year for Barratt Homes (Manchester Division). While working for Barratt homes I was also taking private work on i.e. garden walls, garages and extensions, so in 2006 decided I needed a new challenge. I started taking on private work full time.

Handyman- 8 Apr 2026
Daniel was very efficient and able to utilise his many skills to complete all of the job we required and within a really acceptable timescale given the urgency of it. The refit of our utility room is space saving and the finish is impressive. Additional work in changing parts of the kitchen storage areas were also completed to a high standard. He was timely in keeping to his plans for the job and ensured he kept to his aim for the finishing date. Dan was very courteous throughout as were his assistants that helped out. I’d certainly have no hesitation using him again and in recommending him to others.

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