Upgrading your property's insulation is one of the most impactful decisions you can make for year-round comfort, lower energy bills, and a healthier indoor environment. Selkirk Energy Solutions delivers the best retrofit insulation services for homes and buildings throughout Bonners Ferry and surrounding areas, using proven materials and techniques designed for existing structures. Whether your home drafts in winter or heats up in summer, upgrading what's behind your walls can change how you live indoors, save you real money every month, and reduce your carbon footprint for a more sustainable future.
Many older homes across Bonners Ferry were built before modern energy codes existed, meaning wall cavities and attics often lack adequate insulation. Adding insulation to an existing home without tearing down walls is exactly what retrofit insulation for old buildings is designed to do. According to the U.S. Department of Energy, homeowners can save an average of 15% on heating and cooling costs by air sealing their homes and adding insulation in key areas. Our technicians specialize in accessing hard-to-reach spaces and delivering dense, consistent coverage that makes an immediate difference in how your home performs.
The return on investment goes beyond monthly utility savings. Properly insulated walls and attics reduce wear on your HVAC system, prevent moisture damage, and create a more even temperature throughout every room. We offer a free consultation to evaluate your home's current insulation levels and recommend the right approach for your specific situation.
When it comes to retrofit foam insulation, spray foam stands out for its ability to seal gaps and air leaks that other materials simply cannot reach. It expands into cracks and crevices, creating an airtight barrier that blocks drafts, moisture intrusion, and outdoor pollutants from entering your living space. The result is a home that stays warmer in Bonners Ferry's freezing winters and cooler during summer heat waves, all while using less energy to maintain comfort.
Beyond temperature control, spray foam retrofit insulation strengthens the structural integrity of your walls and acts as a barrier against mold and mildew growth. For homeowners dealing with allergies or respiratory concerns, reducing airborne allergens and moisture infiltration can noticeably improve indoor air quality. Our specialists assess each project individually and recommend the most effective solution, which may include spray foam alongside other materials for a complete insulation system.
Choosing the right material matters when it comes to best retrofit insulation materials. Each product has distinct strengths, and the best choice depends on your home's construction, budget, and performance goals. We work with a range of materials to match every project with the ideal solution.
Dense pack cellulose
Blown-in fiberglass
Spray foam
Material | R-Value Per Inch | Best For | Air Sealing |
Dense Pack Cellulose | ~3.5 | Wall cavities, sound control | Moderate |
Blown-in Fiberglass | ~2.2 to 2.7 | Attics, enclosed cavities | Low |
Spray Foam | ~3.7 to 6.5 | Air sealing, moisture control | Excellent |
Dense pack cellulose is made from recycled paper and treated for fire resistance, making it an eco-friendly option that fills wall cavities densely and effectively. Blown-in fiberglass is lightweight and cost-effective, ideal for attics and large open areas. Spray foam delivers the highest R-value per inch and doubles as an air barrier, making it the top choice for maximum energy performance.

Many homes already have some level of insulation, but that does not mean it is doing its job. Settling, moisture damage, and age can reduce effectiveness significantly over time. Improving existing insulation in buildings involves assessing what is already in place, identifying gaps or degraded areas, and layering or replacing material to bring performance up to modern standards. Our professionals use specialized equipment to inspect cavities and determine exactly where improvements will make the biggest impact.
We install retrofit insulation in a variety of settings, including:
Older homes
Uninsulated wall cavities
The process is less disruptive than most homeowners expect. We use minimal-access techniques that require only small openings, which means no major renovations or extended downtime for your family. Whether your home was built in the 1950s or the 1990s, bringing insulation up to current standards is one of the most cost-effective upgrades you can make. Every dollar spent on retrofitting or weatherizing can yield a significant return in energy savings over time, according to the Department of Energy.
Bonners Ferry experiences long, harsh winters with temperatures regularly dropping well below freezing, making proper insulation not just a comfort issue but a necessity for protecting your home. Retrofit insulation for existing homes in this climate means prioritizing materials and methods that perform reliably in extreme cold and resist moisture buildup from temperature swings. We understand the specific challenges Boundary County homeowners face, from ice dams on poorly insulated roofs to cold walls that never seem to warm up.
Our technicians are familiar with the building styles common in this region and know exactly where insulation deficiencies typically hide. From older farmhouses with no wall insulation to mid-century homes with settled attic fiberglass, we have the experience and equipment to handle it all. We are proud to serve Bonners Ferry and surrounding areas with insulation solutions built for this climate.
If your home struggles with drafts, high energy bills, or uneven temperatures, retrofit insulation can make a real, measurable difference.

Most retrofit projects are completed in a single day, depending on the size of the home and the areas being insulated.
Absolutely. The Department of Energy estimates that proper insulation upgrades can reduce heating and cooling costs by up to 15%, paying for themselves over time.
Spray foam offers the highest performance for cold climates due to its air sealing and moisture resistance, though dense pack cellulose is also very effective in wall cavities.
Yes, dense pack cellulose and spray foam both provide excellent sound dampening, reducing noise from outside and between rooms.
