having a flagstone patio installed

Hiring someone to install a flagstone patio. Right now all I have is a little square concrete step off from the back door. This is going to be going under the deck and out passed the deck stairs. I'd like for it to be as smooth of surface as possible. Also on one side the ground is sloping away from the house, so we are having a retaining wall built too. What do I need to know and look out for when they are working this project? What suggestions do you have? What questions do I ask? Thanks.

Simply consult your blueprints for the installation specifications or speak to your landscape architect .

Kristie,
We just enlarged our patio and had flagstone installed for the patio & a 5' walkway around the side of the house. Here are a few photos. The first shows the flagstone without the grout. The June 3 photo was made looking down from the back porch; the stones look a bit gray as it was prior to it being washed after the grout was put in. Another is the finished project (we still have some things to finish in the landscaping, photographed yesterday (June 26), but it doesn't really show all of the patio. We have a pretty good slope on our lot with a lot of open space between the patio & woods, and we had to keep some slope for drainage. It still is very "level" in terms of the stone. Our table & chairs, flower pots, etc sit very level on it. You have to expect a few rough spots because it's natural stone. The only thing I can suggest is just make sure your installer understands what you want in terms of the finished job & you reject any stones with a rougher texture than you'd like.

Wow. That's gorgeous. Thanks for sharing the pictures with us.

Wow that is nice. He didn't mention grout, but I do like that. He said something about some powdery rock/gravel to go in between. Grey breeze or something? I wonder if he's mixing that with concrete to make a grout. He said there wouldn't be a lot of space in between the flagstones. Maybe he meant the powdery rock for in between the stepping stones.

Thanks I have more questions to ask the landscaper.

I don't know what grey breeze or a powdery mixture would be unless it is something that hardens when water is applied. I would be careful about using that, however, as it will wash out and will also allow the flagstones to shift. You also have much colder ground temperatures in C.S. than we do, so maybe you have to consider the potential for ground "heaving" in the installation. I just prefer to have something permanent like a concrete-based grout between the stones.

Often the gap between stones is filled with natural or a polymerized sand. The sand is dumped onto the surface and swept around to fill the gaps. In the case of the polymerized sand, once the gaps are filled and all excess sand is removed, the surface is carefully sprayed with water to harden the sand. This is more common when installing pavers with a more uniform gap.
