I have well over 20 years in the trades and trust their work. If I were to gripe or nitpick anything it would be the installation of the gable vents on my cape cod home. It appeared they were just foamed in with no mechanical fasteners. Time will tell, but that would be my only concern. Other than that, they were punctual, friendly, and cleaned up after themselves. I would definitely recommend.

I spent several months waiting for window wraps, was given a price, and when they showed up, they refused to honor that or do the work!! Infuriating me and wasting several months in a very particular climate here in central new york.

First had spray insulation done for our cape home a couple years ago that made a big difference. Second time was recently for some window updates (based on state funded program). Both workers were timely, helpful, informative and did solid work. I trusted both guys hands down. Office staff has always been supportive as well. When I initially contacted them, I did email through the website and I did not hear back so I called eventually. Also, I've read that one reviewer saw a tasteless tv ad by these guys that more political than it should've been? I never saw this and though I don't agree with that, the work they've done for us has been solid. I will use them again when needed.

There were a lot of technical…read morechallenges along the way but Halco worked through it all and stood behind all their work every time. I recently needed service work done. They once again did a great job. When we went with them they were not the lowest price for the install. We went with them because we felt they had the staff and the knowledge to do the job right and be around for a long time. We were correct. No regrets here.
