Now that the
electrical work is finished, Jason and I were able to get into the attic to take care of the insulation. Since we already had some cellulose bagged up in the attic, we decided to continue using cellulose. Especially since it is considered environmentally friendly (85% recycled content plus it takes less energy to make vs other insulation choices).
Reminder: we have had ZERO insulation in the attic since
this summer. The old bathroom fan used to vent into the attic, which caused some of the cellulose insulation to rot - good job P.O. Jason bagged up all the crummy insulation, plus some nasty trash to throw out (wood chunks, dehydrated squirrel, crumbling wallet, an old bank statement...). But there was a lot of good insulation left, which Jason also bagged up and stored around the edges of the attic. Honestly, I'm glad he did it. I believe it was this time-intensive act that allowed our electrician to figure out how to get new Romex up into the attic without cutting holes in our plaster walls. It was just unfortunate that it took our electrician TWO winter months to get into our house to get that job done.
On Saturday we started by patching up any cracks or holes in the attic floor. The goal is to prevent any moisture or heat from accessing the attic from the rest of the house. Some of the holes were freshly made by our electrician, so we plugged them with perfectly sized wood dowel chunks and gorilla glue. We also used
Great Stuff Insulating Foam Sealant for the cracks. You can also see that we stapled orange plastic tape to the roof to mark the locations of the bedroom fans and the stairwell light.
But I need to be perfectly clear - the attic doesn't really have a "floor". Just joists with plaster & lath between the beams. I would feel this terrible vertigo every time I went into the attic because I had to balance on the beams the whole time we worked...if we stepped on the plaster/lath, we may break through the ceiling. Talk about stressful.
Once the hole patching was done, we had to lay plastic sheeting as a moisture barrier. Jason found this awesome 15' wide clear plastic sheeting which meant we only had to cut 2 large sections and two smaller sections to cover our whole attic. We started at the north side of the house, laying the plastic from east to west. You staple down the edge, then dip the plastic down between the joists (so it lays directly on the plaster/lath) then allow it to rise over the next joist. We stapled the plastic along the joists with heavy duty staple guns to hold it in place. The plastic is laid over all the electrical wiring. This part of the project took the most time, but it helped that we each had a staple gun. Once we laid down one section of plastic, we started dumping Jason's bagged insulation onto the plastic at a good depth. We used a rake to even things out.
Partway through the process of laying that northern portion of attic insulation, we had to take a break to rent the blower. We rented a cellulose insulation blower from a major tool rental company in town. It was the same place we rented the floor sanders when we first purchased the house. The blower only cost $45/day, plus $8 for insurance. It came with a 50' hose, but since were weren't "quite" sure that it would be long enough, we also paid $10 for an extra 50' hose (which we never needed). What worked to our benefit was that the company was closed on Sundays, so we could pick up the blower on Sat afternoon and not have to return it until Mon morning. And we only had to pay for one day - woo hoo!
On Sunday we worked on the south side of the house laying the other large chunk of plastic and dumping more bagged insulation. As expected, we didn't have enough insulation saved from Jason's bagging, so we planned to take care of the rest of the attic by using the blower and fresh new cellulose insulation. Once the rest of the plastic was laid and stapled, I went downstairs to work the blowing machine. Jason stayed in the attic to direct the hose.

The machine was quite big: 44" high and 33" in diameter (it's a circular blower - see 2nd photo). Plus it was monster heavy: 165 lbs. Thus there was no way we could take it upstairs into the attic. We also don't have a outside attic wall vent to blow insulation in from the outside. That meant we had to haul the blower into the mudroom to allow the hose to go up the stairs, into the attic. We taped off most of the doorway between the mudroom and the kitchen to keep things as clean as possible.
This was definitely a dirty project. I still laugh to think about the drawings on the insulation bags. They show a smiling woman running the blower in a short sleeved shirt - no mask, no goggles, and no gloves. I would have been a wheezing, red-eyed mess without that extra gear. My job was to shove a square chunk of insulation into a circular blower. Next, press the agitator switch for the blades at the bottom of the blower to start breaking up the insulation into smaller pieces, then press the blower switch to start blowing the insulation through the hose. By the way, there wasn't a lid on the machine. Talk about messy! Jason had purchased 6 cubes of
Green Fiber Cocoon Insulation (cellulose) and it was just right for the leftover space. The insulation, foam sealant, plus the plastic cost about $100.
Insulating your attic: $163.00.
A warm bedroom and bathroom: Priceless.
Sunday night we were amazed at the immediate difference in the house. On the first floor I no longer HAD to use a blanket when laying on the couch. We no longer HAD to run a small floor heater in our bedroom right before going to bed to warm up the room & bedsheets. I also no longer had to dread stripping down to take a shower. I am in love, love, love with our warm and toasty house.
Next weekend we plan to take care of our drafty mudroom door and installing a deadbolt lock or chain...
