"The Estimate: The representative arrived as scheduled. We entered the crawlspace and he examined the area to be insulated. Photos were taken. We discussed in depth the one area that might cause problems and insured that I was aware that area might be problematic. He asked if I had further questions then informed me he would get an estimate after discussing the job with others at the office. A few days later the estimate arrived and it indicated in detail what would be done. Everything was outlined as I requested, giving particular detail to the one problem area. The Scheduling: After accepting the work description I was contacted by a scheduler giving me a specific day that the work would be done. The job details were covered again, I was informed of the deposit required, and was insured the job would be completed as described. The actual work: The work crew arrived as scheduled and on time. The first worker arriving once again briefly discussed what would be done. A short time later the crew boss arrived and he insured me that the work would be done as required. We briefly discussed the one area (the problem area) of concern and I was informed he was aware and would do his best to complete it. The work began. All of the old insulation batting was removed, bagged, and taken out of the crawlspace. I was amazed that there was such a small quantity of existing insulation. All of the rim joist areas were filled with foam as specified, then thick batting was applied to the perimeter walls and sealed in place with foam. The problem area was “opened up” and the foam was blown into that area. Upon completion I was informed that it would smell for awhile in the crawlspace but nothing was hazardous about the odor. I was shown some photos of the work completed. Later in the day I inspected the area. The job was very complete. The concrete walls appeared as if a military drill instructor had supervised the work. Everything was cut level and even and looked very good. I looked at the problem area and was amazed at the great quality of the work. That evening I noticed that my furnace did not fire up as often as usual and that the back room of the house above the problem area was much warmer than before and now the same temperature as the rest of the house. Follow Up: Within a few days I was called by the scheduler and informed that if anything needed additional work, to give him a call. The final bill was sent. Recommendation: Polyseal insulation gets a very high recommendation from me. The company used the minimal number of workers required to do a fantastic job. The area was left free of debris and I was informed to call if anything was not done as expected."

"They sure took their time in doing things. Left things in the yard like screens that weren't damaged. didn't clean up messes. Didn't do add-ons I asked for. Did things I didn't want. No communication unless I called them. Mostly that is how contractors operate so I don't hold it against them too much We'll see when the bill comes. They should hire a woman to do their cleaning for them.

Insulation questions, answered by experts

It’s technically possible to install loose-fill cellulose insulation without a blower, but it’s much more time-consuming, tedious, and dangerous. You’ll need to wear the proper protective coverings to handle the cellulose after it’s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.

That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they’ll rent out the blower at no extra cost.

Insulating a detached garage won't reduce your home's heating or cooling bills—and insulating an attached garage will only have a small effect on your home's energy efficiency. However, insulating an attached garage can reduce the transfer of heating and cooling to and from the outdoors, which can reduce the amount of energy your home needs to stay comfortable. Also, having an insulated garage is just more pleasant. Balance the cost of insulating your garage with how you'll use the space to determine if the project is worth it.

Yes, brick houses are better insulated, because the bricks slow down the passage of air from the outside to the inside and vice-versa. This helps to stabilize the internal temperature of the home. When combined with proper residential insulation, brick houses are more efficient and better insulated than other types.

You do not need to drywall over most types of garage insulation. However, doing so can increase noise reduction, make the space more attractive, and keep children and pets from touching harmful fiberglass insulation. If you’re using cellulose or some other type of blown-in insulation (fiberglass and mineral wool are common), you will need drywall to contain the insulation material.

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.
