My home was built in 1958. I recently had progress energy come out and do an energy survey of my home to see what I could do to make it more efficient. I found out that at least the middle of my attic space if not my whole attic is missing insulation. Due to the low pitch of my roof and the vaulted ceilings in side my choices are limited on how to insulate the attic. Most companies want me to tear our my plaster ceiling in order to insulate. A few companies say they can insulate through the soffits but I'm afraid there will be high and low spots that may cause moisture problems. In the meantime I want to do something to help improve the energy efficiency of my home. There are rebates through Progress Energy (the name is changing to Duke Energy) to help fund the improvements so I figured it was worth a try. I called all the companies on the list provided and decided to go with Energy Saving Systems mostly because of price but also because I have used them in the past to spray the crawl space of another home and was sure they would do a good job. While this is far from a professional quality video I thought it would be beneficial to share what the process looks like just in case some of my followers might want to have in done to their home.
The steps to insulating your walls.
1. Pull the furniture and curtains away from your exterior walls. Spray foam follows the path of least resistance and it does find its way through our outlets at times. I had piles of spay foam in front of 2 outlets. Two other outlets had a little foam on the wall. The rest didn't show any foam escaping.
2. Turn off your power. Depending on who you talk to you need to have your power off for a few hours to a couple of days. The manager at Energy Saving Systems said a couple of hours. His technician said it would be fine after 20 minutes. They were done at 11:30am and I left my power off until 5pm.
3. Next the techs came and drilled holes every 8 inches all the way around my home about chest high. As you can see in the video they drill through the seams. I think it makes it easier for them to drill and easier to patch the holes.
4. Fill the cavity inside the block with foam. They fill the first hole until the foam comes out of the hole next to it. They then plug the first hole and move down the line continuing the process. After placing seven or eight holes they pull out the plugs and reuse them. I was surprised to find a few unseen holes in my concrete block as the foam started to seep out of them. I felt really good about having this process done when I saw those holes filled up.
5.Clean off the extra spray foam from the walls and ground using a broom.
6. Back fill the holes with cement. The tech used what looked like those bags used to ice a cake to fill the holes. I thought it was genius because I would have probably used a bucket and trowel which would have been way harder and much messier.
7. Smooth the concrete.
8. Clean the interior walls and floor.
One of the big reasons I like to watch workmen perform their trade is that I find it demystifies the process. After watching them I began to wonder why the other companies wanted to charge me so much money for the same job.
I now have a much tighter seal on my home. Time will tell if it was the smart thing to do. It has already given me piece of mind and that means it was money well spent. Next is to address the attic insulation problem None of the companies will do a similar process to fill the attic space with spray foam because it is such a wet product. I'm trying to find a dryer spay foam option which I hear is available up north. If you have any suggestions I'd love to hear them. I'll report back if I find success. Putting at R30 insulation in your attic gives you one of the highest returns on investment by reducing your electric bill quickly. I am also going to have my ducts sealed. Progress Energy found two ducts that need attention. Take advantage of rebates as they are available to make your home improvement projects less costly for you. I have a feeling as energy costs continue to rise that these features will be more in demand as you sell your home.
