John & Gert Larsen

Our experience working with Armin and Annemarie and all the staff at A&A Services and Marine Contracting has been very positive. The process of procuring a lot in Cognashene, building a bunkie and a cottage has taken place over the last 6 years, which was the time frame that we had requested. A&A was very helpful with liaising with the municipality and securing permits for installation of the septic system and building construction. As the projects proceeded communication was good in order to keep us informed of progress. Any issues that arose were promptly dealt with to our complete satisfaction. Now that we’re done we are very pleased with the level of quality in the construction and finishing of both buildings as well as the landscaping. A&A brings a level of knowledge and expertise that can only come from having successfully completed many custom, high end building projects in a pristine area that presents numerous construction challenges. This experience enables them to advise on design, materials and techniques for all facets of the project. Most importantly all A&A staff were professional, responsive and enjoyable to work with. We look forward to many years of enjoyment of our property in this special part of the world and happily provide this testimonial to A&A’s service.
