Not long after I sent an enquiry, I received a phone call from Melbourne Pet Doors. It was explained to me very clearly the procedure and what to expect. I have laminated glass, and was told that the glass may crack during installation.
A tradesman came about 10 minutes early. I showed him the door where I wanted the installation, and he went straight to work.
The result: The pet door looks terrific and I couldn't be happier. Best of all: no cracks! Also, very reasonably priced.

Approximate cost: $395

I'd like to recommend Joe Monea, who was assigned to sell my home. Joe kept me informed with numerous phone calls, as well as monthly emails and face to face vendor meetings. I was kept informed of every open for inspection in great detail. Joe was always polite, and respected my wishes without judgement. He was very honest with me, and did not put any pressure on me. In fact, everything that I was told from the very first meeting actually happened. My experience with Biggins & Scott was indeed a positive one.
