Signa System

Five stars to Signa System Inc for the work they did last month in my two bedroom unit in a high-​rise, glass wall condo building on Sheridan Rd, Chicago. While noise abatement was not our main reason for undertaking the project, it turned out to be the very first improvement we noticed. Except for fire trucks and the occasional unmuffled motorcycle, traffic noise has virtually disappeared. Our main goal was to keep the north facing windows from frosting — actually, freezing would be a better word for it, with a quarter inch of ice buildup on the coldest winter days. The windows have been done for a month now, and not a speck of ice. A fringe benefit, hoped for but not known for sure, was to keep humidity at a higher level. Sure enough, with an evaporative humidifier running, we are now able to keep humidity at an average 30% instead of 20% before. This in turn is gradually straightening out our engineered wood floors, which previously had been curling at the edges in the coldest, driest months. The job was started when scheduled and completed on time for the agreed-​upon price. Professional but friendly crew. This project was not cheap, but given the value of our condo it was probably the best single investment we’ve made in a long time. Hats off to Signa.

I invested $ 1800 in window insulation for a master bedroom on LaSalle. I was promised 80% noise reduction yet it’s impossible to tell anything has been done (easy to measure since the guest bedroom is adjacent with same windows). I didn’t jump to any conclusions and thought there may have been an installation error so I asked them to come back and take a look. The follow up was so unprofessional, accusatory, and unsettling that I never wanted them back in my home. I’ve tried to let it go but a year later this bad investment is still weighing on me and I feel it’s my duty to protect other consumers.
