I've had major renovations over 2 years, and my experience with Peg makes my top 3 worst renovation experiences.
The measurer was prompt, but interrupts a lot, and in the end, was off by a few inches as he insisted we couldn't fit a specific cabinet where we did.
The lead assembler seemed constantly shocked that I wouldn't drop everything to go fetch parts from IKEA for him as he discovered they were missing. No, it was not possible as per company policy to check in the beginning what was missing, and give the duration of the renovation (2-3 days) to either go get them or arrange to have them delivered.
The supervisor just yells "you need to read the contact!" in response to any disagreement. I had to yell over him many times, "you need to let me finish talking!"
The receptionist, while very nice, has likely had formal mediation training. It makes you wonder about a company whose receptionist has/needs mediation training.
The quoter was great and knowledgeable, but called back with 10 minutes before he had to leave when I was trying to resolve a time-sensitive problem. I had to call him back, but couldn't reach him because none of their emails give their direct extensions, so if the receptionist is away, there's no way to reach any one quickly. Seems a bit odd that people are so hard to reach directly.
Renovations never go off without problems, but, the true nature of the company shows through in how it deals with problems that come up. From my experience, problems will get you yelled at and/or ignored at Peg.
My advice: Either stick with contractors/tradespeople you already know and love, and pay the possibly higher price, which I should have done. If you have the time and ability, assemble it yourself, saving yourself money and aggravation. Or, have low expectations, and you won't be disappointed by Peg.
