Excellent Installation & Professional Team

From design to installation, the entire process was smooth and professional. The team was highly skilled, punctual, and respectful of our property. Our residential elevator works perfectly and has added great value to our home.

Thea. G

Homeowner,

To say that this 3 month modernization was a Herculean task would be an understatement.

I remain convinced at this time, 2 weeks prior to occupancy that no other construction firm could have handled such a task and pulled it off successfully. For well over ten years I have had the opportunity to work with Mattlock Construction on projects from modernizations to complex alteration.

Josh Harvey

-Property Developer

Communication was excellent both ahead of the works at pre-planning stage.

Mattlock has consistently demonstrated their commitment to the success of these projects during all phases… I regard Mattlock Construction as a highly professional and reliable general contractor.”
