Rob and his team just finished the job at my house. They were very professional and careful with my house. I have an 1898 four-square in the North Hills with all of the original plaster. They were very careful with the walls and respectful of my original hardwood floors too. I can already feel a difference in the house and it is amazing how much road noise is now blocked from the insulation. Great job and i would recommend these guys any day of the week. Thanks! Jeff
