Older homes have character. But that charm often comes with hidden problems—especially in the attic and crawlspace. These areas weren’t built to modern standards. And after decades of wear and tear, they can become weak points in the home.
If you own a home built before the 1980s, keep reading. This guide explains why older homes need targeted attic and crawlspace maintenance—and how American Crawlspace can help.
Outdated Insulation and Air Leaks
The Problem: Old Materials Don’t Work Like They Used To
Decades ago, insulation materials were less effective and less durable. Over time, they settle, break down, or become contaminated with dust, pests, or moisture. What used to provide protection now just takes up space.
Old insulation also means air leaks. Gaps in the attic and crawlspace allow heated or cooled air to escape. That drives up your energy bills and makes your HVAC system work overtime.
The Fix: Upgrade to Modern Standards
New insulation is better—plain and simple. It seals tighter, lasts longer, and improves your home’s energy efficiency immediately. Add air sealing, and you’ve got a system that keeps outdoor air out and indoor air where it belongs.
Moisture Damage and Mold Risks
The Problem: Leaks and Poor Ventilation
Old homes are prone to roof leaks, foundation cracks, and outdated ventilation. Over time, these add up. Moisture enters the attic or crawlspace and sits there. That leads to mold, mildew, and rot.
Worse, air from the crawlspace flows up into the rest of the home. If it’s full of mold spores, your family breathes them in.
The Fix: Moisture Management and Mold Remediation
American Crawlspace installs vapor barriers, checks ventilation, and eliminates mold at the source. We remove old, contaminated insulation and stop the cycle of damp, unhealthy air before it spreads.
Rodent and Pest Infestations
The Problem: Easy Access Points
Older homes often have unsealed gaps, rotting wood, or damaged vents. These act like open doors for rodents, ants, spiders, and other pests. Once inside, they nest in insulation, chew on wires, and leave behind droppings.
Rodents in your crawlspace or attic are more than a nuisance. They cause real damage—and carry serious health risks.
The Fix: Rodent Exclusion and Ongoing Monitoring
We don’t just trap pests. We keep them out. Our rodent exclusion service finds every entry point and seals it tight. Then we clean out the contaminated materials and keep watch with routine inspections.
Inefficient or Unsafe Ductwork
The Problem: Old Ducts Leak Energy
In many older homes, ducts run through the attic or crawlspace. And many of those ducts are poorly insulated—or not insulated at all. This leads to heat loss, uneven airflow, and unnecessary strain on your HVAC system.
The Fix: Duct Sealing and Insulation
Our team evaluates your ductwork and upgrades it with proper insulation and sealing. You’ll notice more even temperatures, better airflow, and lower energy bills.
