"They are a very professional organization. Their workmen do a very good job and an excellent job of cleaning the area before they departed the job site. I can tell immediately that the extra insulation they placed in the attic is doing its job by reducing our utility bills."

"This crew was very professional in regards to the installation of my blown -in insulation and their interactions with me, but the mud work they did to repair my walls was sloppy. There were large drips of drywall mud on my furniture, on my sinks, on the floors, on the baseboard trim (especially), and splattered on the walls. In addition, the tape they used to hold up the plastic barrier tore the paint off of my ceilings and adjacent walls which now need to be repaired and repainted. They did repair some of the places on the ceiling and the walls, but they still need to be repainted."

"Their plumber came out. He opened up the wall. He fixed the pipe and insulated the pipe. I have been with them for 15 years and they have fixed everything in my house and it never costs me more than $125.00. They don't try to dodge their responsibility. I have recommended them to multiple people."

"EXCELLENT PROFESSIONAL SERVICE!  Called them cold on a Sunday night from my DC home to repair many shingle caps that had blown off the peak of our roof of our townhome in OC- I could see daylight from the attic and the insulation was wet.  They were on my roof Monday morning, in the rain, fixing it completely.  They took before and after photos on the roof so I could see exactly what they had done. They also replaced a cracked vent pipe boot. 
Very easy to deal with, good communications, knowledgeable and professional.

Insulation FAQs, answered by experts

Each of the three types of wool insulation has particular disadvantages. While their R-value is higher, they all cost more than fiberglass versions. Installing mineral wool and sheep wool requires protective gear. Because of its vulnerability to insects, chemicals are used in its production. Hemp wool is more costly to install than other types because additional tools and labor are involved.

Yes, products made from renewable resources and with reduced chemical impacts.

It’s best not to install a radiant barrier directly under insulation because it requires an air gap on at least one side to work properly. Instead, you should install the radiant barrier over your existing insulation to create an air space to reflect the radiant heat.

Unfortunately, pipes can freeze when exposed to prolonged freezing temperatures, whether or not you have installed insulation covers. Insulation covers, however, are still an excellent idea as they can reduce the chance of your pipe freezing by keeping the pipes closer to the temperature of the water inside the pipe.

Once installed, injection insulation requires little maintenance, but periodic inspections for air leaks or moisture buildup are recommended.
