"I have used Danny at least 10 times. He remodeled an investment property I purchased and did carpentry, flooring , some electrical and plumbing. His work is EXCEPTIONAL and he has the strongest attention to details. His carpentry skills are next level, he rebuilt a stairwell and raised a roof as well. Very trustworthy guy, and did a lot of the work for me with no supervision as the property was in another state. Never had any issues and he sent pictures of the work daily. Additionally after the work was completed I started using him in my personal home in pa and he did flooring/ tile and built shelving, installed toilets and sinks and built a bar in my basement. All the work was great! Prices are very fair !!"

"Inspection went well. HVAC equipment was installed and maintained by Horizon. Technician was on time, and was professional in interaction with me. He clearly explained what he was going to do, and explained the results when the inspection was completed. there were no unexpected charges. Not the cheapest, but I am looking for good, not cheap."
