Attic Insulation & Restoration

Attic Insulation

Oftentimes when animals have been living in an attic for some time, damage to the insulation occurs. Whether your problem animal is shredding and/or moving around your insulation, or soiling it with it’s feces, our trained, certified technicians at Critter Control of New Hampshire will restore it to it’s original state by either repositioning it or having it replaced. After an inspection, the technician will give you suggestions on how to proceed. Depending on the severity of the situation, a spot cleanup for a small soiled area, or an entire attic cleanup may be in order.

Critter Control of New Hampshire is an IICRC (Institute of Inspection Cleaning and Restoration Certification) certified firm, following industry standards for cleaning.

Spot Applications

Sometimes animals may be concentrated in one particular area and damage is contained to just one portion of an attic. In these situations the cleanup is simpler and relatively quick. Our team will quote insulation removal, cleaning, and re-insulation. 


Full Attic Remediation

When animals have taken residence for some time, they can shred and trample insulation, resulting in heat loss in the winter and heat infiltration in the summer. Both instances can cost you tremendously in energy expenses.

In extreme situations, the heat loss from missing insulation causes heat loss into an attic and snow to melt on a roof, resulting in ice dams to occur on the eaves. The ice dams then cause any water behind them to potentially back up into your attic, causing even more costly damage. Animals like raccoons tend to cause total attic destruction in one season, whereas squirrels tend to take longer to cause the same amount of damage.

As animals live in an attic, their urine and feces accumulate. Some animals will actually only use certain areas of the attic. Raccoons and flying squirrels are most famous for doing this. Odors may build up and are sometimes noticed inside the livable portions of the house. Other times it may not be noticeable until warm summer heat forces it down. 

Contained Cleanup

Total attic cleanup is referred to as attic remediation. As with the mold and fire remediation industry, we follow many of the same standards for attic cleanup. From worker protective Tyvek suits & respirators, to working within a self-contained work environment with negative air scrubbers, you can be rest assured that the soiling of your attic will not infiltrate your livable home.

The Process...

Insulation is removed by either bagging fiberglass batts, or removing loose fill insulation with a special truck mounted with an insulation vacuum.

The attic is then vacuumed with a HEPA vacuum.

Use of ozone generators are sometimes used to kill odors in attics.

Wood and masonry (chimneys) cannot be properly disinfected due to their porous nature so we employ the use of special "encapsulation paints." Again, borrowed from the mold & fire industry, these paints seal wood and masonry, locking in odors from urine/feces and any bacteria and/or fungus which may have grown from the animals soiling. attic restorationThis encapsulation looks like a white paint, but be rest assured that the sealers we use are certified to kill existing mold and inhibit any new mold growth. 

After the attic has been cleaned, we start the process of re-insulation. At this time, it is best to start with adding the most you can afford. The more you add, the more your savings will be. We recommend using R-48 rated insulation.

Couple in the fact that attics with missing or matted insulation are losing an increased amount of heat/conditioned air, the cost recoup time is even quicker. Results will vary with every situation.

Attic Capping

Don’t have any soiling issues, but want more insulation?

Attic capping is simply adding more insulation on top of your existing insulation. Installed in as little as half of a day, attic capping is a great add on to the savings for your home.

Houses built in the 70's & 80's typically only have R-19 rated (6 inches) insulation, while the current building codes in New Hampshire call for R-48 through R-60 (14-18 inches) insulation.
