When is it time for new insulation?

When is it time for new insulation?

Some forms of home insulation like fiberglass are meant to last while other types, such as cellulose, will last about 30 years. Still, any insulant can run into situations where its effectiveness is in decline, and replacement or reinforcement is demanded. Here are six good ways to tell if you need new insulation.

Signs on Roof

If your home’s attic has inadequate insulation then you don’t need to look much further than your roof after it snows. If the snow on your roof melts unevenly or at a faster rate than the houses surrounding you this is a good indication that you are losing heat through your home. The formation of icicles around the ridge of the roof can also indicate an issue with attic insulation levels.

Expensive Comfort

Whether it involves turning up the heat in winter or the air conditioning in summer, bigger energy bills might indicate that the home’s insulation is no longer doing its job. Over time, blown-in insulation made of fiberglass or cellulose fibers will sink towards the ground as gravity takes its toll.

Caught in a Draft

One possible indicator that new insulation is required is the occurrence of drafts flowing through the house. A drafty section in a home can also be caused by gaps around doors and windows, though, so these problems should be ruled out first. Regarding insulation, a draft can result from blown-in insulation settling, old insulation decaying, or fiberglass batting insulation not forming a snug fit in the wall, ceiling, and floor spaces. If strong winds can circulate past exterior walls, they can also force its way through individual insulation strands and overcome the material’s thermal resistance.

One Extreme to Another

Since old insulation won’t give out evenly, along with higher costs, another sign of deterioration is noticeable temperature differences from one room to the next. This is sometimes easy to miss if you don’t use some rooms as often as others. Even if the occupants aren’t spending much time in these areas, the heated or cooled air in the home will still be flowing into them and out through poorly protected exterior walls.

Cold spots and constantly needing to adjust the thermostat can be signs of poor insulation

All Wet

If walls or ceilings are leaking or showing wet spots, the water causing it has probably soaked into the insulation as well. This can create a home for mold in cellulose insulation or older materials like cotton or wool. It can also sometimes spawn mold on the paper backing of fiberglass batts.

Uninvited Guests

Both insects and mice find the insulation in walls and ceilings a comfortable location to build a nest. If there’s an infestation indoors that coincides with cracks or gaps in any walls, there’s a good chance some part of the insulation is being used as a home for unwanted pests. In the process, it’s thermal resistance seriously reduced.

What Our Insulation Customers Are Saying

  • A positive experience. The work crew arrived as scheduled. Workers were prompt in setting up and going through the step-by-step process on adding insulation to the attic. I was encouraged to ask questions and to watch as they worked. Clean up of all work areas was performed. We received a follow up call, after the crew had left, verifying my satisfaction.

  • We had our family room insulated by Pro. They arrived on time and performed the work professionally, and in a timely manner. When they were finished, they made sure our property was in the same condition as when they arrived. We did have an issue with the inside trim molding on our patio door wall pulling away from the door wall, but the company that installed our patio door wall came out and fixed it. We have noticed that our family room is warmer than before. We are satisfied with the job Pro did for us and would recommend this company to anyone.
