WHAT OUR CLIENTS SAY
“We are extremely happy with the extensions recently completed on our home by Jamkat Constructions. The end result is even better than we had anticipated, thanks to your attention to detail, professionalism and first class workmanship. We cannot speak highly enough of your reliability, your advice and value for money, and look forward to being able to recommend your company to anyone looking for an A-Grade builder.”
– David & Carol Woods
“We needed a pergola and had some unusual problems regarding the site. We asked a number of companies, none of which satisfied us with their approach... James confidently delivered a plan and gave us a sense of relief that the problem which had looked almost out of reach was totally solvable. James built us a beautiful outdoor area/pergola in a unique and challenging position. The workmanship is outstanding – attention to detail and no shortcuts.”
– Conny & Dawn
“JAMKAT quickly and efficiently brought to life a long awaited building project. James and his crew were a breathe of fresh air in the trade, always on time and on task just getting on with what needed to be done... communicating regularly with us each step of the way and providing clear guidelines as to how best to achieve our build. It was an exciting and very positive experience and I would have no hesitation in recommending JAMKAT or using them again in the future.”
– Kylie & Enzio Diviak
