Why One Room in Your Matthews Home Is Always Different

Hot bedrooms, cold kitchens, and drafty hallways usually have the same root cause: uneven insulation and hidden air leaks. Where the attic insulation is thin or a wall opens into the attic, that room loses comfort first.

Find the weak spots

Read why temperatures differ from room to room to see what causes the imbalance.

Fix the attic

An even layer over well-sealed ceilings evens things out. See attic insulation.

Tackle the walls

Exterior and knee walls can be part of the problem. Our wall insulation service covers them.

Don’t forget the floor

Rooms over a crawl space can feel cold. See floor insulation options.
