Today is the two year anniversary of the beginning of our major home remodeling project. In 2015, we remodeled our main floor which is the living room, dining room, kitchen, and sun room. It was a big undertaking. It all started with our 13-year old dog having an accident on the very old, very gross carpet. We knew the carpet had to go, but we also knew that he would not be able to get around on the wood floors that I wanted to replace it with. His 13-year old Golden Retriever hips did not work so well on slick surfaces. Our poor old buddy Murphy was the only reason we still had the carpet. One day, we left him alone in the house for two hours while we went out to dinner, which was not unusual, but he could not hold his bladder and so he had an accident. But not just any accident, instead of going in one place, he made laps around the living room and dining room. It was impossible to clean. I gave up and went to bed.
The next morning, I ripped out the carpet. If you have ever read the children’s book, If You Give A Mouse A Cookie, you know were this is going. If we were going to replace the flooring then, we should also remove the 1960’s wood paneling. If we remove the wood paneling then, we should go ahead and move the wall and open up the doorway. If we move the walls then, we should move and redo the kitchen. If we redo the kitchen, then we need to put in a new header and open up the sun room. And that is how it all began.
One of the things we wanted to do before we finished patching up the walls was to insulate. Our house was built in 1968 and has awesome thick lath and plaster walls, but no insulation. Even though this was the least gratifying part of the project, I am glad we did it. Why was it the least gratifying? Because once done, no one would be able to tell. It was not pretty or eye-catching. It was completely hidden, but very important. After our remodel, our house was much less drafty on the main level.
Long ago, in the last millennium (1999), I gutted a 2,800 ft2 bungalow built in the 1920’s. My partner and I were trying our best to make our dollars go as far as possible. After putting on a new roof, tearing out the old leaking cast-iron plumbing, patching most of the walls, dry-walling all of the ceilings, replacing the old knob and tube wiring, and installing all new hardwood flooring, insulating was not on the top of my to-do list. In hindsight, insulating should have been a priority. It could easily have been done after the wiring was finished and before the walls had been patched. But honestly, it was not even on my radar.
A friend who came to help lift drywall to the ceiling one day asked if I was planning to insulate. He was a student of architecture with an emphasis on sustainable design. I emphatically told him no. I was drained, not financially, but emotionally. There was no way I was going to add another major project, let alone another major expense, to the project. It was short sighted. I sold the house in 2004, so it is no longer my problem, but it would have been the right thing to do. At that time, I did not even bother to do the math to see what it would have cost.
On our current home, with the help of my very handy dad, I drilled five-inch holes between each stud in all of the outside walls of the living room and the dining room, which is where the new kitchen was going to be. I rented the insulation blower from the local big box home improvement store. I estimated the amount of insulation I needed and bought a little more than that. (Because we all hate running out and having to make an extra trip back to get more, right!)
The insulation was a blow-in cellulose with 85% recycled material and an R-rating ranging from 13 to 30, depending on the thickness. For sidewall application in 4 inch stud walls the most we could expect was an R13. The outside walls are 8 feet high and the stretch of walls that need the insulation was 50 linear feet. I estimated that the space inside the walls to be filled was 132 ft3. According to the package, we needed 7 cubes of insulation at $7.99 per package; the total cost was $55.93. With the purchase of the insulation, the blower rental was a deposit which you were refunded once the blower was returned, in other words, free.
Running the blower with my dad was comedic. I wish someone had it on video. Because the blower was so heavy, we opted to leave it in the back of the truck and park the truck as near to the front door as possible. The downside is that we had to communicate while one of us was inside the house and the other was outside the house. Oh, and the blower was loud. Our first attempt resulted in more insulation being blown around the living room than actually in the wall. But once we figured it out, it was smooth sailing and did not take very long to finish the entire room. We saved the 5 inch plaster cut-outs and glued them back in to patch up the holes.
After blowing the insulation in to our house in 2015, I know now that do-it-yourself insulation is not that expensive. It is a messy pain, but I was actually surprised at how inexpensive it was. It took a little extra time and dry wall mud to patch up the holes, but the money and extra time was a great investment. We lowered out winter heating bills by about $XX per month, meaning that the ROI (return on investment) was only X months! Looking back at my old bungalow, I probably would have saved money on my $400 heating bill hand-over-fist if I had bothered to insulate. Lesson learned. Take it from me, always take the time to insulate if you are doing a major remodel of an older home!
