"

Insulating the exterior walls of our two story, 1700 sq ft house, involved drilling holes between each stud, blowing in insulating material, plugging the holes, spackling over the holes, priming and finally painting the holes.  Two man crew was very efficient in setting up scaffolding and then doing the work described.  We got a chance to see what the insulation looks like inside the wall when the force of the insulation popped out a built-in bookcase that was not secured.  Its a solid blanket of insulation, filling in the entire space.   Very impressive.  The results have been very noticeable.  The house feels more comfortable, and the heater turns on less frequently.  We should have done this years ago. 

Last part of the project was to blow additional insulation into the attic, which went very quickly.  Overall, the project took 2 very long afternoons/evenings to complete.  It makes a mess around the outside of the house, but they did a good job of cleaning up each day.

"Prompt service and good work. The drilled holes in the stucco and the patch work was excellent, can't easily see the patch, if at all in some cases. The only negative is that since they finished after dark, the cleanup wasn't as good as I would have liked."

"I love this company! Garrett came to my home and assessed how efficient our current insulation, etc was. He was very informative and friendly — explained what we needed and how they could help. At the time, I decided to hold off and he never pushed the sale. When I was ready, he was quick to accommodate my schedule. His team: Angel, Luis, Tommy and TJ were great! They arrived early, were professional, courteous, kind, very helpful with my questions and were above and beyond to help fix things that I wasn’t even aware of. They also were more than happy to help with small problems that I had no idea how to fix. They worked quickly and cleaned up afterwards. You could tell they cared about their work which makes me feel confident that the job was done right. They were also fun to have around — my Great Dane loved them too! Garrett and Dave checked in with me during and afterwards to make sure things were going well and if I had any questions. I highly recommend Eagle Shield."

Insulation questions, answered by experts

The best type of insulation for your home depends on your specific needs, climate, and the area you are insulating. For new construction, structural insulated panels are a highly energy-efficient option that is easy to install during the building process. In very warm climates, reflective insulation can be a cost-effective choice. For cold climates, fiberglass is an excellent option due to its high R-value and resistance to settling over time. Spray foam works well in humid environments because of its moisture-resistant properties. For standard attics, loose-fill, spray foam, or blown-in insulation are all suitable options.

Radiant barriers and insulation serve different purposes, so one is not inherently better than the other. Radiant barriers reflect radiant heat, helping keep spaces cool, especially in hot climates, while insulation slows heat transfer through conduction. For optimal energy efficiency, it’s best to use both together. 

Radiant barriers can enhance the performance of insulation by preventing heat gain in the summer and heat loss in the winter. The choice between them depends on specific climate conditions and the building’s design requirements.

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

A dehumidifier can reduce condensation on your ductwork by lowering humidity levels in the air. Condensation occurs when humid, warm air makes contact with cold ducts. A dehumidifier can help maintain your home's indoor humidity below or around 50%, minimizing moisture buildup. However, if condensation is caused by leaks, cracks, or other damage, a dehumidifier won’t solve the problem. 

Also known as sound-dampening blankets, acoustic blankets reduce echo in a room. They come in different thicknesses and materials, and they can be nailed or glued to walls.
