What Our Clients Say

BB
Betty Borg

Jai and the team built a custom home for us. The finishes are perfect and the building process was a breeze. We decided to use Curtis Constructions because we had used them on two other smaller projects previously and on both of those, we were very satisfied.

JP
Judy Phillpott

Really like our new Laundry/Powder Room. Great company to deal with. All tradesmen were on time, cleaned up after themselves and did a meticulous job. Jai (Curtis) was very flexible when we wished to make some changes along the way.

RC
Rachel Carson

We needed a fresh bathroom renovation. Jai & the team worked hard to provide us with the bathroom we wanted and we're very happy with the end result. They protected our floors and communicated clearly throughout the whole process. Job well done!
