Older homes in Central Jersey have charm—but often hidden insulation problems. At Koala Insulation of Central Jersey, we’ve seen the same mistakes repeat, and we’re here to help you avoid them for better comfort and lower bills.

Mistake 1: Assuming Existing Insulation Is Enough

Many older homes still have original insulation—often settled, compressed or missing in key spots. That means gaps, drafts and unseen heat loss. We assess your home fully and suggest upgrades that actually make a difference.

Mistake 2: Skipping Air-Sealing After Insulation

Insulation without sealing leaks is like building a new wall with holes. Cold air still gets in. At Koala Insulation of Central Jersey, we combine insulation with air-sealing around windows, doors, attic hatches and plumbing penetrations.

Mistake 3: Using Wrong Insulation for the Space

Not all insulation types suit older homes. Choosing cheap or wrong materials can lead to moisture issues, reduced R-value or performance loss. Our experts help select the right type—blown-in, spray foam, rigid board—based on your home’s needs.

Mistake 4: Forgetting The Hidden Spaces

Attics, basement ceilings, crawl spaces often go unnoticed—but they’re major heat loss zones. We inspect and upgrade those hidden spots so your whole home performs better.
