Is my house properly insulated?

We get it. Insulation isn’t loud or flashy (literally!) because it doesn’t have a lot of the same “WOW” as solar panels or a new bathroom or appliances. The truth is, home builders didn’t use much insulation decades ago in the homes they were building. Heating fuel and cooling energy were cheap, so the math didn’t work out to bother.

Now that fuel is far more expensive, not having enough home insulation is costing you money.

With the proper home insulation, you can reduce heating and cooling costs, improve your home’s market value, and save the planet. In most cases, new attic and wall insulation can save you as much as 45% on heating and cooling costs.

Home insulation might not look like a lot, but it can make a huge difference. Think of the difference between a well-insulated coffee cup and a glass. Having the best materials in place matters!

“Just a little note to tell you how pleased we are with your job. Your crew was very efficient, polite, neat, and did a great job. Nice to meet all of you, and thank you so much for fitting us in so fast. We sure will recommend you to anyone thinking of having their house insulated.

Energy upgrades pay for themselves faster as energy costs go up

Solar and wind are great for the environment, but they’re also expensive. And many homes may not have the ability to erect a windmill in the back yard. 

No matter how you heat and cool your home, energy upgrades only pay for themselves if the energy cost is high and keeps going up. New attic insulation costs a fraction of what solar panels cost.

What’s an “R” value? In insulation, the “R” stands for “resistance to heat flow”. The higher the R-value the more resistance the insulation offers. R-value comes in two forms:

R-value per inch. Here the insulation comes in varying thickness. Manufacturers rate their products in terms of R-value per inch. Multiply the R-value per inch by its thickness to get the Total R-value.

Total R-value is what it sounds like: a total value of the insulation in a given space. Sometimes the Total R-value can apply to a whole building, including its walls, attic, plywood, siding, insulation, and drywall.

Attic Insulation

Because heat rises, it is most important that your attic is properly insulated. We recommend that you choose either blown in cellulose insulation (recycled newspaper) or Cotton (blue jean batting). We baffle around all vents and recessed lights. We also lay formaldehyde-free fiberglass batts in the attic if you prefer. Both the cellulose and the blue jean batts are non-toxic “green” products.

Floor Insulation

Fiberglass is used in sub-floors. We staple and use rods to secure the batts under the floors. Floor insulation is very helpful if you have hardwood and or tile flooring.

Wall Insulation

Wall insulation not only improves the comfort level in your home, but also improves the sound quality. This process can only be used on existing walls. Fiberglass and blue jean cotton batts are used in additions and new construction projects.

Ceiling Inject

Do you live in a two-story house? Does it ever sound like someone is walking on your head or can you hear the television playing downstairs while you’re trying to sleep upstairs? By injecting insulation between the floor and ceiling, you can create a sound barrier that is much appreciated and effective. This process is performed much like a wall insulation.

Interior Sound Reduction

Do the pipes rattle when you turn on the water or flush the toilet? Do you share a common wall? Do you have a surround sound system in your entertainment room and want the sound to stay in that room? Interior wall insulation will make a significant difference, one you are certain to appreciate. We insulate interior walls in much the same way we do exterior walls.

Insulation Removal

Remodels, home improvements, roof leaks, fire damage, rats and vermin infestation are some reasons for insulation removal. We have the proper machinery to do the job right.

How much insulation do I need? Where do I need it and what kind?

Generally, the colder the climate the more insulation you need. Our professional insulation contractors will show you how your current insulation (if any) compares with what’s recommended for homes in and around Pleasant Hill by reputable rating agencies, like the Department of Energy. 

All Seasons can handle fiberglass insulation, cellulose insulation, spray insulation, and many others that can make for a significant thermal upgrade in crucial spaces of your house.
