How often to book flagstone & natural stone patio
A stone patio is low upkeep, but joints and loose stones need attention. Visits are booked with the pro of your choice, and you can pause or change the plan.
Before you book flagstone & natural stone patio
Quick things that save a trip. Tick them off as you go; none of it is required to book.
Photograph the yard and slope
Take wide shots of the area from the house and from the far side. Include trees, steps, gates and any low spots where water collects.
Look at real stone samples outside
Ask each pro for a sample or a photo of a finished job in the stone they suggest. Wet it and look in sun and shade, because tone and grip both change.
Decide dry-laid or mortared early
The method changes the base, the cost and the upkeep. Think about drainage, furniture and cold weather, and discuss it with each pro.
Mark the layout on the ground
Outline the patio with rope or paint and set out your chairs or table. Check the edges against doors, steps and trees.
Check for buried lines
Locate irrigation, drain and utility lines under the area, and use your local mark-out service before digging.
Ask about stone thickness
Ask what thickness the pro plans for your use and why. Thin stone on a loose base is a common reason for cracking.
Say where in Foster City you are
Add your neighborhood, for example Isle Cove, Carmel Village, and Treasure Isle, or your ZIP code to your notes. Pros choose the neighborhoods they cover, and it tells them how far they have to travel.
