"I had a great experience with this company installing my new boiler. Their pricing was fair compared to other estimates I received. Dave walked me through the entire process and answered all my questions, and his team came in and did a great job with the installation. With so many scammers out there, I truly felt comfortable working with this company and will absolutely use them again in the future."

"I highly recommend this company Heartland Village General Contracting Handyman Services of Staten Island, N.Y. Harvey the owner & his excellent team were professional, punctual & attentative to every detail in building my beautiful handicap TREX brown boards & Grey metal railings ramp to my front door. This fantastic company also closed in my screen house for the rain & possibly snow cold winter months with this beautiful design of Plexiglass. His team also completed odd jobs of installing two door bells, replaced damaged tiles in my kitchen & installed tinting sheets on four kitchen windows which I love. Thank you Harvey & your professional team of excellence. Sue M. - Staten Island 9/12/25"
