"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."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"They custom make the windows and Fed-Ex them to you. We installed them ourselves to save money. Once we put them in, we couldn't hear outside noise anymore. It made a world of difference. I think it has also helped insulate my home a little. For the cost, I think it would have been twice as much to have the windows replaced."

"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 questions, answered by experts

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.

Installing new insulation in a home is worthwhile if your existing insulation is old and has lost some of its insulative capability or if you don’t have insulation installed already. Installing new insulation will boost your home’s energy efficiency, which can reduce your heating and cooling bills and save money on HVAC repair and maintenance in the long run. New insulation also keeps your living space more comfortable, so you and your family will benefit from the work as well. Finally, installing new insulation boosts your home value, making it especially worthwhile if you plan to sell.

Air duct insulation typically lasts for 10 to 15 years or even longer, depending on the material and maintenance. It's important to conduct periodic inspections to check for signs of deterioration, such as water damage, tears, or general wear. If you find any of these issues, it may be time for repairs or a full replacement. You might also consider upgrading your insulation even if it's in good shape to improve your home's energy efficiency and enhance your HVAC system's performance with newer, more effective materials.

Insulation prevents heat transfer, which keeps your home cool in summer and warm in winter. Regulating the temperature in your home is not only more comfortable for you, but will lower your heating and cooling bills—it’s a win-win. Make sure to determine the correct amount of insulation to ensure it is enough for your home and climate.

Canned spray foam has an R-value of R-3.7 per inch. However, it’s not great for use as insulation. Also known as single-component spray foam, it doesn’t expand as much as two-part types that work for insulating the whole house. Save the canned foam for gaps around doors and windows.
