Most insulation questions in Rutherford County come down to one thing: is what's already there still doing its job? Insulation doesn't last forever in every situation. It can settle over time, get compressed during roof or HVAC work, absorb moisture from a leak, or be damaged by pests. In other homes, it was never installed to today's levels in the first place.
That's why every Bonham project starts with an assessment of your existing insulation. We check its type, depth, and condition, look for moisture or pest damage, and identify air leaks. From there, the recommendation usually falls into one of three categories:
Add to it. If existing insulation is dry, clean, and evenly distributed but too thin, additional insulation can be installed over it.
Remove and replace it. If insulation is wet, moldy, contaminated, or badly compressed, it should come out before new insulation goes in.
Leave it alone. If it's performing well, we'll tell you, and point you to any other issues worth addressing.
We bring the same approach to older homes, renovation projects where walls and ceilings are opened up, rural properties with additions or outbuildings, and new construction, where we install code-compliant insulation in coordination with your builder.
We add insulation to under-insulated attics and remove and replace insulation damaged by leaks, pests, or age.
We insulate walls and floors during renovations, additions, and new construction to cut down on drafts and cold floors.
We pull out fallen or water-damaged crawl space insulation and reinstall new insulation properly between the floor joists.
Blown-in fiberglass covers attic floors evenly, filling around framing, wiring, and ductwork, and can usually be installed over existing insulation.
Fiberglass batts are a dependable choice for open walls during a remodel, floor joists, and new construction framing.
We seal leaks at attic penetrations, top plates, chimneys, and other openings so heated and cooled air stays where it belongs.
A moisture barrier over the crawl space floor helps limit ground moisture and protects new insulation from the conditions that damaged the old.
Insulation for commercial new construction, renovations, and upgrades to existing buildings in Rutherford County.
Rutherford County sits where the foothills begin climbing toward the Blue Ridge, so homes here see real seasonal swings: cold winter nights, warm and humid summers, and shoulder seasons that can change quickly. Properties around Lake Lure and Chimney Rock, at the edge of the mountains, may see cooler temperatures and more moisture than homes in Forest City or Spindale.
For existing homes, those seasonal swings tend to expose problems that have built up over time:
Renovation is the best opportunity to fix these issues. When walls, ceilings, and floors are already open, insulation can be replaced or upgraded with minimal extra disruption. For homeowners who aren't renovating, attic and crawl space upgrades can usually be done without opening finished spaces at all.

Signs include rooms that are hard to keep warm in winter, an upstairs that overheats in summer, cold floors, drafts, and rising energy bills. In the attic, insulation that doesn't fully cover the floor joists is a good indicator you need more. A free assessment will tell you for certain.
Lake-area homes generally benefit from the same fundamentals as other homes: a well-insulated attic, thorough air sealing, and properly installed floor insulation. Because humidity can run higher near the lake, crawl space moisture barriers and regular checks for damp or sagging insulation are especially worthwhile. Seasonal homes that are closed up for long stretches should also be checked for moisture and pest damage.
Yes. Heat naturally rises, and in an under-insulated attic it escapes through the ceiling. Adding attic insulation, along with sealing air leaks, helps your home hold the heat your system produces, which can make rooms feel warmer and more even on cold nights.
Yes. Wet, moldy, or fallen insulation should be removed, not covered or patched. Leaving it in place can trap moisture against the floor framing. We remove the damaged material, recommend addressing the moisture source, and install new insulation, often with a moisture barrier to help protect it.
Yes. Renovations are one of the best times to insulate. We insulate additions, remodels, finished attics, and rebuilt spaces, and coordinate with your contractor so insulation goes in at the right point in the project.
Think of insulation as a warm sweater and air sealing as a windbreaker. The sweater keeps heat in, but on a windy day cold air cuts right through it. The windbreaker stops the wind. Air sealing blocks the drafts that carry heat out of your home, and insulation slows heat loss through the attic, walls, and floors. Together, they keep your home more comfortable and help your heating and cooling system run more efficiently.
If your insulation is old, damaged, or you're planning a renovation, now is a good time to find out where your home stands.
