Insulation Replacement

Reinsulate Your Home in St. George, UT for Comfort and Efficiency 

Is your home drafty in the winter or too hot in the summer? If your energy bills continue to rise and your HVAC system appears to be working overtime, your insulation may be the culprit. Reinsulating your home, especially if it’s older, can dramatically improve comfort and reduce energy costs. 

Fiberglass blown insulation install in an attic.

At Big City Insulation Utah, we specialize in helping homeowners in St. George and surrounding communities upgrade their insulation without tearing down walls or disrupting your daily life. 

Is Replacing Insulation Worth the Cost? 

Many homes in Southern Utah were built with outdated or insufficient insulation. Over time, insulation settles, deteriorates, or becomes less effective. Reinsulating your home can: 

  • Lower monthly energy bills 
  • Improve indoor comfort year-round 
  • Reduce noise between rooms and from outside 
  • Prevent moisture buildup and mold 
  • Boost your home’s resale value 

Signs Your Home May Need Reinsulation 

If you’re experiencing any of the following, it’s time to consider reinsulating: 

  • Uneven temperatures between rooms 
  • Cold drafts in winter or hot spots in summer 
  • High heating and cooling costs 
  • Pest issues or moisture in the walls 
  • Your insulation is over 20 years old
