What our customers have to say:

“After owning my home for 12 years I have had the best yard just last year, the first year Costello Landscaping took over the treatments.  Though we replaced the top soil and planted new grass the first year we lived here when the front landscaping was done, there has always been an unevenness in the color, plenty of weeds and some bare spots.  Last year (the first for Costello Landscaping) there was an even color, thick growth, few weeds, and no bare spots for the first time.  Costello Landscaping also did excellent jobs with extras such as eliminating the weeds on the front stones and trimming the arborvitae in the back.  I highly recommend them to my neighbors.”

Don – Plainville CT

“Great group of people doing excellent work! I have used them for various services over the years (planting, monthly mowing services and snow plowing) etc… They are always professional, punctual and a pleasure to work with. I can not recommend them enough.”

Amy W. – Farmington, CT

“Costello Landscaping is a really great company with quality work. They don’t cut corners and care about theend result. Their crews are very knowledgeable and pleasant from start to finish. My lawn renovation came out wonderfully! I highly recommend them.”
