Back in 1939 when our home was built, quality insulation was not a high priority. After dealing with ice dams for one winter too many, I brought in an energy consultant to help prioritize and determine the most effective steps to insulate our home. After her report was received, it was time to choose an insulator to help execute it. It was clear from the very beginning that my estimator, Ben, knew construction and building science, and could see the construction challenges that the multiple additions to our home presented. Compared to the other bid I received, I felt I was receiving a higher level of expertise from Rockwiler. When I had questions or needed clarifications on the bid before approval, my emails were answered efficiently and clearly. As our home is a cape cod style, accessing parts of the roofline required cutting some new access panels in hidden places. When a question came up about where to best cut a panel (the cutting is done by a 3rd party contractor), I was able to call Rockweiler, and an estimator was at my house in 30 minutes to consult. The final job consisted of -first coordinating with my roofer, to sprayfoam the ceiling of a flat-roofed bathroom addition, after the roofer removed the existing roof then: -removing batt insulation from the 2 side attics of our front addition, cutting the edge of the subfloor open at the edges to access the top of the walls, and re-insulating with sprayfoam -densepacking the slanted walls (back of roof) in the front addition and original house roof -sealing the attic around the chimney -adding insulation to the back addition attic -covering our dirt crawlspace with plastic sheeting, sprayfoaming it to the walls, and sprayfoam insulating all crawlspace walls and sill plates What was done right during the work: -not terribly messy for the job being done -polite and professional work crew -willing to explain what was being done, answer my questions, and keep me updated -willing to make small deviations from the quote- such as adding sprayfoam in a small area that wasn't originally discussed -when we found that densepack had escaped from a roofline into the garage while being blown in, they didn't hesitate to go add a line of sprayfoam at that joint. My biggest criticism is that accessing an attic space required taking all the shelves out of a closet. When they were done with their work on Friday, they left w/o reassembling the shelves, so I had to do it. I mentioned this on the feedback form, and an estimator called me, apologized, and said they'd talk to the crew to make sure that restoring the customer's house to order takes priority. They were also very professional when I pointed out some minor drywall damage- they sent someone over to address it, no questions asked. I'm looking forward to seeing how my house holds up to winter this year, but I'm sure it will be much more pleasant after Rockweiler's work. I wouldn't hesitate to recommend them to anyone.
