Working with Maddison Construction on a recent project has been a highly positive experience. They have consistently demonstrated professionalism and commitment to quality. When an issue arose due to a subcontractor’s oversight, Maddison went above and beyond to help rectify the situation, ensuring that the client will be pleased with the outcome. Their proactive approach and dedication to resolving problems made a significant difference, and we truly appreciate their efforts.

Working with Maddison on the Canada Post Parkade Refurbishment has been an excellent experience. The nature of the project meant that we had tight timelines, and a client that was scrutinizing the project outcomes very closely.

Our PM Scott Martin was diligent, always kept me up to date, and coordinated everything seamlessly with the consultant.

The work site was well organized and well set up. Safety barriers were erected and maintained throughout the work.

I had an opportunity to tour one of the real estate directors for Canada Post around the parkade while the work was underway, and we met with the supervisor of the caulking crew on the top level. He detailed the work scope, explained what the crew had done so far and what was left to do, and gave a timeline for completion. The director was very impressed with his politeness and knowledge.

Although there is still some outstanding scope due to a material shipment error, all in all the job went very well. I would not hesitate to invite Maddison to bid future work for JLL.

I am writing to provide a letter of recommendation for Mr. Daniel Maddison and his team from Maddison Construction Ltd. in reference to work completed here at the University of Guelph – Kemptville Campus over the past number of years.

Maddison Construction has assisted with several projects including restoration and repair work on our Administration building foundation, retrofit of two conference rooms at our W.B. George Centre, Washroom repairs and renovation in our Residence buildings, several concrete ramps, slab and curb repairs, bollard installation to protect well casing and other miscellaneous jobs.

The projects no matter the size were addressed in a safe, timely and professional manner with minimal disruption to campus operations – our students, staff, and customers.

Daniel and his team(s) provided great service and customer care throughout each project and worked with the University to meet our tight timeline and budget.

Manager, Physical Plant Services - University of Guelph

Daniel and his team are personable, professional, thorough and are clearly very knowledgeable. MCL’s level of preparation, safety and execution make them the ideal partner for us and we look forward to working with them moving forward.
