"I like working with this company. Rob Blake, the owner, is very professional. I called him because a hot water heater problem had revealed that the foam from a 2011 job had not filled the cavity in the wall as thought during the 2011 job.  I did not know if this only applied to the water heater closet or to the entire cabin.
Rob's response to my call was "That's why you have a lifetime warranty!"  Wow.  Not used to that.  Rob came out the next day and crawled around under the cabin and poked wires into outlet cavities and showed me that the foam was only thin in the water heater closet, and given the construction of the closet, that made sense.  Rob wanted to schedule a return within a few days to fix the problem before the weather got cold.  I asked him to bid the top floor of my house to do at the same time.
The fix was free and the top floor of my house was 3200.  So altogether, I have spent $7100 with retrofoam, to insulate three houses; one about 750 square feet; one about 450 square feet and one about 4,000 square feet.  
As with the first job, the workers were polite, professional, hardworking and very thorough. They were very nice about things like taking down a bird feeder for me - not part of their job at all, and they were happy to help me with it.  They do have to come inside to listen for something when certain walls are being injected; they were always very polite, wiped their feet and so on.  They worked from 8 to 5 every day, and they did an excellent job of cleaning up after themselves.  The job was planned for two days but took three.  They were very inobtrusive with my renter whose water heater closet they redid.  In fact, they removed some fiberglass insulation near the water heater placed during the water heater repairs not only because it was ineffective but because the type that was there was a potential fire hazard (the paper side was near the water heater).  This is pretty typical of them; they have gone above and beyond on every job for me.  They really do work as if they were insulating their own homes.  Very nice.
The only almost-rough spot is that my cabin and my house had to be drilled right through the exterior siding, and after the holes were plugged, we needed to repaint the house.  The 750- square foot house needed to be painted anyway so I didn't mind, and I planned the big house job to coincide with a painting soon after because I remembered that from last time, and it also was due for a repainting.  Rob tells me that only five houses so far have had to be done this way; but I would ask him before the job if the house will need to be repainted as it would have been a pretty rude shock to not realize this ahead of time.  I understand that most jobs do not result in a repainting, this was about the type of siding we had on our houses.
In fact. Rob offered to supply the labor to restain the plugs to match the siding, but since we are repainting soon, we didn't see any need.
The insulation has been astonishingly effective.  Not only in retaining temperature, but also the houses are now so very quiet.  This has been an excellent investment in our house, and we are very happy with the outcome.  Also, this is a very professional, easy to deal with company.

"The team worked at my house for 2 days.  Day one, the blew insulation in the 10" of insulation in my attic and began installing R19 insulation in the floorboards. Day two, they completed the R19 insulation and ran the aeroseal through the ducts.  The guys did a great job.  Cleaned up after themselves, which my wife really appreciated, and my power bill has gone down drastically.  Just to provide some prospective, my January power bill was $525 in a 1900 SF house!!!  Since Energy Sharks came, my power bill has been less than $130 each month."

"The Moore brothers were great. They satisfied my Home Owners' Association with a detailed proposal within an hour of inspecting the job. They itemized and described the work, which included cleaning off the mold, replacing insulation, repairing joists, encapsulating the crawlspace, and creating a French Drain on the exterior of my unit to redirect the rain. They also set up my dehumidifier in the space with a wireless meter I can read from inside . Their price was in line and they did everything they promised in good order, good humor, and respect. Three other companies bid and were not even close... in promptness, plan, OR price. I highly recommend Jon and Danny Moore."

"They installed solar panels as per contract. They were on time and removed all material when done. I had roof damage from a storm and they repaired it at no extra cost. So far I am happy with this company and plan on using them again for house repair.

"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."

Insulation questions, answered by experts

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.

At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep’s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don’t run into any issues, such as flooding or mold, that shorten the lifespan.

The most energy-efficient windows are double—or triple-pane windows with low-emissivity (Low-E) coatings and gas fills between the panes. These windows reduce heat transfer, prevent drafts, and help maintain a consistent indoor temperature. But if replacing windows isn’t in your budget, pairing your existing windows with insulating window treatments can still make a noticeable difference in home comfort and monthly bills. 

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

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.
