Happy Clients

The results have been amazing. Our yard is dry even after heavy rains this summer, and the sump pumps in our basement, which typically run constantly, have been very quiet since the project was completed. Janine and her crew are honest and responsive and were great to work with at every stage. We couldn’t be happier with the whole experience. Many many thanks.
– Cathy and Chris

Janine and crew were efficient, professional and excellent through each phase. We are happy with the beautiful retaining wall, planters and walkway. Highly recommend for the craft they do and professionalism.

A big ‘Thank You’ goes to Janine Williams-Greer at Dillon & Semenovich Inc for creating a much more appealing look to our driveway! I’m blown away by Janine’s talent, time and professionalism! The only thing left to do is finish our address plaque and we are set until spring, when we’ll do some gardening in this space!
