Report
Tom, Jack and the crew from Coy's recently completed the framing for a large renovation and they were absolutely fantastic. Due to COVID I was working from home and was able to be quite involved and the team always were accommodating and professional. I feel very happy and comforted by their attention to care, detail, quality and the level of craftsmanship they displayed and the end result is far better than I ever could have imagined. Would definitely recommend.

Tom and the team helped transform our single story, three bedroom, dated home into an incredible double story five bedroom house. We couldn't be happier with the result. The team kept us informed along the way with their useful app and daily updates. Tom also recommended small changes along the way to improve our overall build. The turn around time was exceptional during a difficult time with Covid and lockdown and we thank them for their support, professionalism and our new family home. I would highly recommend engaging with Coy's for your next build or reno.

Tom and Jack did an amazing job of remodeling and renovating our deck into a beautiful outdoor room that can be used all year round. The team at Coy's are professional, reliable and highly skilled. Their customer service and care is exemplary. Tom communicated with us throughout the whole process, ensuring that the project was meeting our expectations. Both Tom and Jack are so easy to work with, they listen, ask questions and offer considered suggestions. Thank you to you both for the work you have done at our home. We love our new outdoor space!
