I have asked many builders renovations before. I can say Karl is the best builder i have ever met. He is so friendly, efficient, honest etc. Even when I have asked him extra additional jobs, he was willing to help us. Highly recommended. Only thing I am afraid is that I will not be able to take him when we need him next time, if I recommend him here.
Karl and Matt are brilliant! They were onsite renovating our 1920s bungalow in Westmere for 4 months and we cannot fault their work or the results. From the begining Karl was upfront about costs and when any issues arose (as they do in an old home) he had plenty of possible solutions. He ensured the sub contractors operated to his standards and we found working with him easy. We have plans for further work and will be calling Karl to come and do it – suggest you do the same if you are looking for a builder who has pride in his work and is reliable
RoyRenovation and Landscaping
Karl and his team worked on our house for a few months, renovating the bathroom and laundry and fixing many other building issues we had in the house. Karl always had a smile on his face and dealt with all the issues we faced in a logical manner. He often made suggestions of how we might fix an issue and always helped us to work out the cheapest option. Karl is a great builder and an honest, reliable person.
SusanRenovation and Maintenance
I needed some TLC and repairs done as well as some outside work/ drainage, on an older property (1930’s). It was a smaller job but Karl & Matthew, were really flexible, did it willingly, worked fast and keept things tidy as the job progressed. I was always kept informed and updated. Karl is a great problem solver and found solutions that kept costs down and enhanced the property. Thanks guys, will gladly use you again!

Karl and Matt undertook a large project on our Villa that took approximately 1 year. Both were very reliable, easy to communicate with and always worked with me to help solve issues and make sure I was getting what I wanted. I would definitely recommend KF Builders to anyone considering a building project and I will also be using them again
A+ builder. Karl was very professional and went great guns through the list I gave him. Highly recommend.
