"Great !! Gabriel was on time and went right to work. He took pictures of duct work before and after. He supplied my wife and I N95 masks to wear during the cleaning keeping us safe. Gabriel was a true professional."

"The job was done - my duct was cleaned thoroughly."

"Shawn was on time and worked efficiently. He did a great job cleaning the hood and kept the rest of the kitchen clean while he cleaned the hood. He checked his work when he was done. I was happy with the service provided"

"He was vey professional, all windows were super clean, friendly, polite, picked up and cleaned after his work. Outstanding."

"I'll start by saying that I have severe allergies. and respiratory issues Jason and Mike were not only NADCA certified, but friendly, knowledgeable, punctual, and most importantly... honest. I had spoken to others that said they would "fix" it", but Cornerstone came, evaluated my system and, rather than charge me unnecessarily, they provided me with other options that they did not even offer. That's service!!! I look forward to scheduling them when my system is actually DUE for a cleaning. Thanks gentlemen!"

"The tech was prompt and did quick work of cleaning and inspecting."

"They were excellent! Not only did they clean my house perfectly, they were prompt, professional, and beat everyone else’s price. I would hire them again in a heartbeat."

"Recommend Joslin & Co for window cleaning. Hands down the best not just for service but the great customer service as well. You can tell Nico takes great pride in his work with the care for the building and his customers! He is a really cool down to earth guy yet still professional and quick and efficient in his services! 10/10 in my book."

"The pro did the work of cleaning out the dryer vents. However, they left without discussing what they learned from the work. The picture that they sent with their project completion did not have particularly good pictures and did NOT show the lint that was removed from the vent exhaust. Moreover, the summary description of the work simply said that no problem was detected. Nothing about the exhaust cleaning. I called the office. The lady I spoke to kept talking about the quality work they did which did not answer my question about the lint removal. She did say there were pictures attached to the report. I agreed, but it was only of the vent and the roof. She sent me additional pictures that clearly showed the volume of lint removed on the roof. In my opinion, this whole experience could have been avoided if 1) the report summary explained that lint was removed, in addition to "there were no problems noted", and 2) all the pictures taken by the technicians been included."

"Mike did a wonderful job cleaning our windows inside and out and power washing our home. Thought the price was reasonable. He was professional and personable."
