"It was a complex project. They were very careful with their procedures and raised sunken concrete sections next to the house and around a pool to allow for drainage. They filled the major cracks. They were courteous and on-time over several days. After many years the water in the basement problem has been resolved."

"G & G landscaping did an amazing job! Giacomo worked with us to refine the job and keep it within our budget. It turned out better than we could have anticipated. We needed to contain a hill that was eroding. Instead of a retaining wall, he had the idea to use very large boulders that matched the boulders around our pond. The end result looks like it was installed when the pond was installed. He and his crew worked nonstop until it was finished. They took care not to damage the yard with their heavy equipment and took the time to consult with me a few times during their work. I highly recommend them for hardscaping. Honest, dependable, punctual, and respectful of the property"

"They were the first company that got back to me which was within a couple of hours. They were able to come the next day to spray. The technician realized that the quote they had given me was for some services that were not needed so he called the office and had the price reduced by $60. He came back a couple of days later to make sure the spraying had taken care of the problem and to seal up the cracks where the bees had entered."
