Robert Calnan and his crew replaced all the windows in my house and added insulation in the attic. My energy bills were reduced by half. He recently replaced a door that was in tough shape. He and his crew do excellent work, communicate well, leave no mess, and do it all with a smile! I will be hiring him again soon for another project.

They gave different options for insulating the rim joistand explained the pros and cons of each. They were personable, unobtrusive and communicative. Despite running into some significant unforseen problems with the job, they stuck to their estimate.

Rob and his crew’s work was exceptional. His initial consultation gave me a great deal of confidence about moving forward with a difficult construction job, then the actual work was impeccable. Rob organized and handled all communications with vendors (dumpster) and updated me regularly and with great detail. His work was professional, fast, and very clean. He will always be my first phone call for any contracting work I need done.

The roofing company we hired to reshingle our roof suggested that we consider upgrading the attic insulation, and recommended Rob Calnan. Rob came by the day we called him. He was very attentive to our schedule, and went out of his way to fit us in, and through the entire process was readily available and responsive both to cell phone and email. The work took five days, and after each day we received a call about how things went, and what would be done the next working day. This is a family business. Several of his employees are his own children. He takes great pride in the quality of the work

I recommend Calnan's without hesitation. From my initial telephone inquiry to completion of the job, Rob Calnan answered my calls and emails right away. Amazing! We got nine new windows, and it was a seamless undertaking. Rob and his employees took care of every detail and go above and beyond. The staff is unobtrusive, polite, and totally professional. Plus, they leave the place immaculate. Calnan's is a highly professional company. We really appreciated the excellent communication through every step of the process and the completed job is top notch.
