The short answer

Attic Fanatics does attic insulation across the southern half of Lehigh County, Pennsylvania. We remove failed insulation, air seal, and install R-38 by default. The number comes from the inspection, not a phone quote. Free inspection, written estimate first; same-day generally available when the schedule allows.

Insulation Services across Lehigh County

Insulation work across Lehigh County is usually most effective when it starts with a real attic inspection. We look at condition, contamination, coverage, and the age of the existing material so the finished job is based on what the house needs.

We serve Allentown, Emmaus, Coopersburg, Macungie, and the southern half of Lehigh County.

Our crews run out of Jackson, NJ, and stop at about 1 hour 50 minutes out. Whitehall, Coplay, Slatington, Hanover Township, Alburtis, and the townships north and west of Allentown are past that line, and Allentown and Macungie sit right on it, so the address check in the form decides those streets one by one.

What insulation work usually includes

Assess current attic performance

We inspect the attic to see whether the current insulation is helping, failing, or hiding a larger restoration issue.

Remove damaged or contaminated material

If the existing insulation has been compromised, we remove it cleanly before a new installation goes in.

Install to a higher standard

Fresh insulation should cover properly, perform properly, and leave the attic in better condition than we found it.

Lehigh County Insulation Services FAQ

Free inspection. No obligation.

Can insulation help after rodent or wildlife damage?
Yes, but only after the contamination and entry issues are addressed first. We do not recommend covering up damaged insulation and calling the attic fixed.
What type of homes in Lehigh County benefit most from insulation upgrades?
Older homes, homes with patchy attic insulation, and homes that have had rodent or wildlife activity tend to benefit the most because their thermal barrier is already compromised.
Will new insulation help lower energy waste?
In many homes, yes. Proper attic insulation helps slow heat loss in winter and heat gain in summer, which improves comfort and supports more efficient system performance.
Are you licensed and insured in Pennsylvania?
Yes. We are licensed and insured to perform insulation and attic-related work in Pennsylvania.

We already know which service you need. Your info and address are enough to start.
