We Fix Bad Attics in South Jersey
Air leaks, old insulation and improper ventilation are the most common causes of low indoor air quality, uncomfortable rooms and high energy bills. Book your free inspection to take control of your attic.

Signs your attic is costing you
Many South Jersey homes built before 2000 are under-insulated
Insulation settles, gets disturbed, and was installed to older standards. If any of these sound familiar, the attic is the first place to look.
Hot upstairs, cold downstairs
Bedrooms that never cool off in July and a first floor that stays drafty in January.
Energy bills keep climbing
The heat or AC runs constantly and still can't keep up with the thermostat.
Old, flat or dirty insulation
You can see the ceiling joists, or the insulation is gray, compressed or damaged.
What we do
One crew for the whole attic, done in the right order
01
Insulation removal
Old, compressed, wet or contaminated insulation vacuumed out and hauled off site. Nothing gets dragged through your house.

Attic cleanout
Debris, old storage and loose junk cleared out so we can see and work on the whole attic.
Learn more03
Attic decontamination
Surfaces sanitized and deodorized so the attic is clean before anything new goes in.
04
Air sealing
Gaps around lights, pipes, wiring, chimneys, top plates and the attic hatch sealed tight. This is where much of the comfort difference comes from.
Learn more05
Attic baffles
Baffles set at every eave so insulation never blocks the soffit vents.
06
Blown-in insulation
Cellulose, fiberglass or mineral wool blown to an even depth at the R-value recommended for South Jersey.
Learn more07
Batt insulation
Mineral wool or fiberglass batts cut and fit tight, with no gaps or compression.
08
Attic ventilation
Soffit, roof and gable vents checked and corrected so the attic breathes. Good airflow protects the roof and keeps moisture out.

Questions
What homeowners ask us
How much does attic insulation cost in South Jersey?
It depends on attic size, what is up there now, and whether the old insulation has to come out. A top-up over clean insulation costs far less than full removal, air sealing and new insulation. After the free inspection you get a written price for each option, so you can compare before deciding.
Do I need to remove my old insulation?
Not always. If it is clean, dry and just thin, we can air seal and add new insulation on top. If it is compressed, wet, moldy, or full of droppings and debris, it should come out first, because new insulation over a dirty attic traps the problem and never performs as rated.
Why air seal before insulating?
Insulation slows heat moving through it, but it does not stop air. Gaps around lights, pipes, wiring, chimneys and the attic hatch let warm and cool air leak straight through. Sealing those gaps first is usually where the biggest comfort and energy gains come from.
How long does the job take?
Most attic jobs take one to two days. Removal, air sealing and new insulation on a larger home can run longer. We give you the schedule in writing with your price.
Is it messy?
We cover and seal off the path from the door to the attic before we start. All the old insulation and debris goes out through a window, not through your living space, and we haul it off site. Then we seal everything back up and leave your home clean.
What happens at the free inspection?
We go up and photograph your whole attic, measure your insulation depth and R-value, check for air leaks, ventilation and moisture, and look at the crawl space if you have one. You get a photo report and written options the same day. There is no obligation.
