 Trustindex verifies that the original source of the review is Google. I asked Leo to do a lot of work that needed done for my new house. He pointed out a lot of major issues that I had missed which I was so thankful for as this is my first house so I didn't really know what to look for. His communication is fantastic! Anything I needed or any questions I had he would get back to me with no issues. Him and his team were brilliant and very friendly. They paid attention to detail and they always tidied up after them. If i had any questions they would explain it to me in depth so i understood. They know their stuff and I would highly recommend them. Communication is a big thing for me and Leo was absolutely amazing. Leo and his team are very skilled at what they do and I am so happy with the results. I now feel safe in my first new home. Thank you!

 Trustindex verifies that the original source of the review is Google. I couldn't recommend North Building Contractors enough as they have gone above and beyond to make sure I have received my dream door for my house as soothly and easily as possible for me.
They have made the process a lot less stressful as they do everything themselves and go out of their way for the clients.
I will definitely be using them again in future to do additional jobs as I can not get over how amazing they handle everything which benefits people and families who have very busy lives and want the stress free experience with professional service and with an exquisite outcome.
Thank you Leo and your team for all your hard work.
You definitely get what you pay for.
