Commonwealth Landscape Lighting

Commonwealth Landscape Lighting is an Acton company that designs, installs, services and maintains landscape lighting systems, by its own account for residential, historic, educational and commercial properties. It says it has been in business 35 years and lists twelve towns in its service area, from Acton and Concord to Wellesley and Weston. The owner, Mark Piantedosi, has been quoted on thisoldhouse.com advising do-it-yourselfers to place fixtures no closer than 20 feet apart. One recent Google customer hired the company for a lighting installation about eight years ago and still uses it for maintenance and changes as their lighting needs shift. A customer of over a decade says Mike and Mark are quick to respond when a lamp fades or a spring clean-up is needed. A recent Google reviewer says that after the company installed their lights, it came back the next night to check the effects and made adjustments. On a recent service call, a customer says the technician arrived within the agreed window, made a few repairs, added two lights and followed up afterward to make sure they were happy. In a February 2026 review, a customer said Mike and Mark designed and installed a lighting system for their backyard and pool area, combining up lighting, down lighting and path lights. A 2025 Google customer wrote that the company installed color-changing landscape lighting and worked lighting into their new pool and patio projects, and said Mike and Mark showed up when they said they would and left everything clean. On Google the company shows 5 stars from 16 ratings, and on Houzz 5.0 from 4 ratings. Houzz lists a Certified Low Voltage Lighting Technician credential, a Massachusetts Certified Landscape Professional credential and a Massachusetts Certified Arborist credential.
