General Contractor in St Catharines

Our Work Speaks for Itself!

Frontyard Stairs and Backyard Interlock
Oakville, Ontario

Ryan's attention to detail was outstanding—he carefully covered the system water valve within the stairs, preventing any exposure and preserving both the look and functionality of the project. His expertise and foresight were evident throughout.

- Kristoferson
New Backyard Deck
Welland, Ontario

Ryan and his team were professional and careful with our property throughout the project. They took precautions to avoid damage, from demolishing the old deck to driving machinery through our narrow gate while protecting the lawn.

Ryan kept me updated and offered smart suggestions to improve the final result, all while staying within budget.

- James Toronto

Ryan and his crew did it again! I had them do my kitchen after they did such a beautiful job for my master bath and my deck! I didn't even consider anyone else for the job! Ryan is very trustworthy and keeps you informed every step of the way!

Moving & Storage
Burlington, Ontario

Ryan and his team (Dylan & Chris), were amazing to work with! We had a patio built and most of our backyard altered. The team also set up our gazebo and backyard furniture. They ensured that my wife and I were informed of everything, and constantly happy and satisfied with the project. Great communication and very friendly, yet professional people. Ryan ensured us of his work and he lived up to every word of it. We are very satisfied with his work. Recommended 100%!!

- Mike
Drywall Contractors
St. Catharines, Ontario

Ryan and his crew are incredibly professional. Very good communicators. Reliable. The site was kept clean, they swept the street multiple times a day while moving fill. Measurements for 12' deep excavation, retaining walls were bang on. Every City inspection passed first time around. Watching them excavate, build forms, pour footings & the walls was fascinating. Ryan is super smart.

- Sunny
Bathroom & Deck renovations
Hamilton, Ontario

Ryan & his crew are very good at their jobs! Very consistent with the quality of the job they do! I would recommend them for any job you have. I like their work so much, that I will hire them again for my kitchen renovation! The job is not finished yet but I know I will love my new bathroom and deck!
