01 / Insulation
Insulation and duct work for Los Angeles homes
Insulation and ducts decide how comfortable a house feels on a hot afternoon and how hard the air conditioner has to work. Denali Builders CA installs and repairs insulation and duct systems for homes in the Los Angeles area, and we pair the work with attic and roof repairs when the two are connected.

Assessment of where a home is losing or gaining heat
03 / Attic and roof
Why attic and roof work belong together
The attic sits between the roof and the living space. A roof leak can soak insulation and make it useless, and a hot, poorly ventilated attic works against both the insulation and the ducts running through it. When we are in the attic, we look at the roof deck and the ventilation as well, and we tell you if the roof needs attention before new insulation goes in.
