Extensions- 8 Nov 2021
Nicky was the only builder to call out and view the site prior to giving a quote, which I’ll add was a fair quote landing in the middle of the 4 we received. Upon meeting Nicky and Darren we knew the job was theirs, they were friendly, approachable but to the point. They worked with us, understanding our budget and plans for the house, and advising us where necessary. Every step of the project they kept us in the loop, they were onsite everyday and the work was clean and tidy, they were very professional dealing with our neighbours also! I will 100% use Nicky, Darren & co again, and would strongly recommend them to others. I can’t fault them in any way! This was the biggest home project we have done to date, and it was They even left us a card and gift, which was a very nice touch!

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

An extension builder in Carrickfergus 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.
