The good news is that it is indeed possible to add insulation to your old house without compromising its structural integrity or historical features. By following professional guidelines and working with experienced contractors, you can significantly improve your home’s energy efficiency and comfort without causing any harm. In this article, we will explore the steps professionals take to insulate old homes safely and provide you with valuable insights into the process.

1. Conduct a Thorough Assessment

Before starting any insulation project, a professional insulation contractor will conduct a detailed assessment of your old home. This assessment helps identify potential areas that may be prone to damage during the insulation installation. Additionally, it enables the contractor to determine the right insulation materials and techniques to use for your specific home.

2. Choose the Right Insulation Materials

Selecting the appropriate insulation materials for an old home is crucial to preserving its integrity and historical features. Professionals will often recommend insulation options that can easily be installed without disrupting the existing structure. Some popular choices include blown-in cellulose or fiberglass insulation, spray foam insulation, or rigid foam boards. These materials can provide effective insulation while minimizing the risk of damage.

3. Consider Prime Insulation Locations

Insulating an old home typically involves focusing on certain key areas. These commonly include the attic, walls, floors, and basement or crawl space. By insulating these prime locations, professionals can target key areas where heat loss or gain occurs, helping to improve overall energy efficiency.

4. Insulate the Attic

The attic is often the first area professionals look to insulate in an old home. Insulating the attic can contribute significantly to reducing heat loss, as heat rises and can escape through the ceiling. Depending on your attic’s configuration, the contractor may choose either blown-in or batt insulation. Properly insulating the attic can lead to substantial energy savings and increased comfort throughout the house.

5. Wall Insulation Techniques

Insulating walls in an old home requires extra care to avoid damaging the structural integrity and historical features. One common method professionals employ is the drill-and-fill technique. This involves making small holes in the walls and filling them with blown-in insulation. Once completed, these holes can easily be patched up, leaving minimal visible impact on the walls. Alternatively, if the walls are undergoing renovation or if insulation is being added during a remodeling project, removal of the wall covering may provide access for installing insulation batts.

6. Floor and Foundation Insulation

Insulating the floors and foundation of an old home can provide substantial benefits in terms of comfort and energy efficiency. Professionals may consider using rigid foam insulation panels or spray foam insulation to insulate crawl spaces, basements, or the foundation walls. By choosing non-intrusive insulation methods, contractors can ensure that your old home remains intact while achieving higher energy efficiency.

7. Seek Professional Expertise

When it comes to insulating an old home, seeking professional expertise is imperative. Experienced insulation contractors understand the complexities involved in working with old homes and can provide tailored insulation solutions that align with your home’s specific needs. They have the skills, expertise, and tools required to execute the job effectively, ensuring your home remains intact throughout the process.


Insulating an old home without causing damage is entirely possible when done by professionals who take the necessary precautions. By conducting a thorough assessment, choosing suitable insulation materials, and focusing on prime insulation locations, contractors can insulate your home effectively while preserving its historical features. Whether you opt for attic, wall, floor, or foundation insulation, remember to rely on the expertise of experienced professionals who will ensure your old home is enhanced with improved energy efficiency and comfort, all while maintaining its unique historical charm.
