"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

No, you should avoid using antifreeze in your outdoor spigot to prevent freezing. Antifreeze can contaminate your water supply and harm the environment. Instead, employ safer and more effective methods for winterizing your spigot, such as draining the spigot and using insulation, to protect it from freezing temperatures.

Insulating under a concrete slab foundation is a great way to improve the energy efficiency of your home, but it isn't necessary for outdoor projects like driveways, patios, sidewalks, and walkways. If you’re pouring in cold weather, insulating under the slab can help prevent heat loss from the concrete, aiding in proper curing. Along with accelerants, this can be a good way to ensure strong concrete despite pouring in the cold.

Closed-cell spray foam insulation itself serves as a vapor barrier (or vapor retarder). However, you may need to install a vapor barrier if you have open-cell spray foam insulation. When in doubt, work with a professional insulation contractor, as they can provide more detail about the specific needs of your home in your climate.

The heat loss through a poorly insulated attic when you’re running your furnace or heat pump during cold weather can be as high as 25%. This means you could see significantly higher energy costs to make up for this heat loss. The cost of adding insulation to the attic may eventually pay for itself through lower energy bills. If you decide to add a radiant barrier too, the radiant barrier cost may also pay for itself over time.

Polyisocyanurate foam, or polyiso for short, has the highest R-value per square inch: 6.5 to 6.8. Polyiso is a rigid foam that comes with a reflective foil on both sides to serve as a radiant barrier. Given its high R-value, rigid foam is usually meant for foundations and basement walls.
