We are a small Commercial Construction Company; over the last six months we have worked collaboratively with Matrix Estimating to tender our larger scale projects. Cormac is a pleasure to work with. He has a broad knowledge of the building industry. A good understanding of interpreting plans and specifications. Always very thorough, with fantastic attention to detail and time effective delivery of information required. Cormac takes on each project as if it were his own. We cannot recommend Cormac highly enough and will continue to work together in the future.

I have been using Cormac and his team at Matrix Estimating for the past 4 years on a weekly basis for my Carpentry quotes. Cormac’s attention to detail is second to none . He has vast knowledge right across the building industry involving multiple different trades. Cormac is extremely honest, reliable and professional which sums up all his team at Matrix. His communication skills are excellent, he always remains calm and gives great advice on the best way to approach a potential project to try and secure the work . I trust Matrix estimating fully with my quoting .They use the most up to date software and their markups are at the highest level which are labelled and easy to read for my clients to see what’s allowed in the quote. They also offer support after the project has commenced which great for any questions which I may have. Matrix also provides short videos about the job so you can watch it at a time that is convenient to you which I find really useful and you can look back to refresh your memory before the job begins. I highly recommend Matrix Estimating if you want confidence in your quoting and want to increase your turnover and grow your business. Martin Larkin Director Woodland Carpentry

Matrix Estimating has been quoting Cavanagh Corp's projects for the past year and half, and we have had a great success rate on winning projects both Commercial and Residential, I feel that with the highly detailed quotes and drawing markups it really gave us an edge over our competitors to win the projects, and we have had great feedback from our clients of how professional our quotations look, I would highly recommend Matrix Estimating.

Matrix Estimating helped us price our home renovation works recently. They were able to provide us with a detailed estimate on each trade after assessing our drawings. The service was professional and the staff were experienced and knowledgeable. I highly recommend Matrix Estimating and would definitely use Cormac and his team again.

Matrix Estimating commenced quoting jobs for my company in May 2019. I found using Matrix Estimating has helped me win more business. Having Matrix Estimating take on the quoting for jobs has given me more time to focus on other aspects of my business. Professional, efficient and high quality work. I would recommend their services to any builder or subcontractor who does not have time to do the estimating themselves.
