Review of Grassers Plumbing and Heating

Heather was wonderful to work with. She is very knowledgable and took time to provide guidance to choose a product that was best for an elderly person. It was a smooth transaction including delivery and installation of a wall oven.

Review of Grassers Plumbing and Heating

I was planning on calling Gary or Heather to tell them what a positive experience it was to have Matt doing the installation. You couldn't have sent a better guy to do the job but you have a trove of great people working for you but being long time customers from our days as builders to us being retail customers you guys are the best,and we thank you 😊
