Insulation is one of the smartest investments homeowners can make. When done right, it boosts energy efficiency, lowers heating and cooling costs and improves overall comfort. But when done wrong? Insulation mistakes can quietly sabotage your home’s performance and cost you thousands over time. At Advanced Seal Indiana, we’ve corrected our fair share of common missteps—and we’re here to make sure you don’t fall into the same traps. 

Whether you’re building, renovating or retrofitting, avoiding these insulation mistakes is key to creating an efficient, long-lasting barrier against outdoor temperatures. Learn how to spot the warning signs, make informed choices and when to call in the pros. 

One of the most overlooked insulation mistakes is neglecting to seal air leaks before adding insulation. If your home has gaps or cracks, heat and air can still move freely—rendering even the best insulation ineffective. This is why our home insulation solutions always start with a full air sealing assessment before we apply product. 

Another mistake we see often is using the wrong type of insulation in the wrong place. Fiberglass batts, for instance, are popular but not ideal for irregular spaces or areas prone to moisture. Spray foam, on the other hand, seals and insulates at the same time. Our spray foam insulation services are a favorite for clients looking to protect attics, crawl spaces and rim joists without risking air gaps or moisture build-up. 

Installing insulation without considering ventilation is another problem. Without proper airflow, moisture can build up behind the insulation and lead to rot or mold. This kind of moisture damage can degrade your insulation and reduce its R-value significantly over time. 

How to Avoid Costly Insulation Errors 

The number one way to avoid insulation mistakes is by working with trained, certified professionals. DIY efforts often result in compressed insulation, missed cavities, blocked vents or unsafe handling—especially when older insulation materials like vermiculite are present. Certain old insulations may contain asbestos and should only be removed by qualified contractors. 

Our team at Advanced Seal Indiana is equipped to evaluate your entire building envelope. We use infrared imaging to locate problem areas and perform professional-grade installation that adheres to current building codes. If your attic insulation is underperforming or your crawl space is drafty, you might be facing insulation mistakes that can be corrected quickly and affordably.
