Angelo's Southern Tier Spray Foam
Angelo's Southern Tier Spray Foam
we like to do estimates on Saturday but we will do are best to accommodate everyone's schedule
"We hired Angelo's spray foam and Russ a terrible job installing the spray foam you missed spots throughout the ceiling everywhere. We sent him pictures showing him spots he missed and spots that weren't as thick as what we paid for. He agreed that the quality of work was terrible and said he would come and fix it. After 12 weeks of not showing up and making up excuses of why he can't get here, he eventually told us he's not going to fix it. My wife and I filed a lawsuit against him. Too tired to redeem our money to pay another company to come and fix his work. Would not recommend this company"
