Kelly and his employees have worked in our townhouse complex for a number of years doing various jobs. Such a new fences, putting new pavers at the front of each unit and on all the walkways, fixing leaks in basements, patching up our roadways, adding hand rails to our steps. He is very fair in his pricing and very good at what he does. I would recommend him in a heart beat.

Calderone Contracting have completed a # of projects for me.
They have : Repaired the top of the well and replaced the lid.
Refinished my driveway removing old railway ties to create a new side border.
Resurfaced the side entrance steps and replaced the railings.
Totally remodelled my 44 yr old bathroom.
Removed my old kitchen to create a completely new modern looking one.
Also removed an old deck to give us a new much larger one for our enjoyment.
I would highly reccomend them to anyone looking for top quality work from a friendly team who take pride in the quality and precision of their work and total clean up.

I’ve known Kelly, the owner of Calderone Contracting, for a long time both personally and professionally, and he truly cares about his work and clients.
I also hired him for a kitchen renovation at my workplace, and the experience was excellent from start to finish. The project was completed on time, the results were beautiful, and communication was always clear and consistent. There were plenty of great product options, colours, and finishes to choose from as well.
Kelly and his team were a pleasure to work with. I would definitely recommend Calderone Contracting.

Kelly and his crew did a fantastic job in widening our driveway, creating an interlocking stone path to our backyard, and installing a matching interlocking stone patio up to our deck steps.
We were very impressed with the crew's focus and attention to detail.
