We would highly recommend D&N to anyone! After a different company kept postponing our appointments, we gave D&N a call and they came out very promptly to do an estimate. Within about 3 weeks they were able to get us in and added insulation to our attic. Everyone on the team that we encountered was very professional. They were very thorough, going above and beyond to make sure that the job was done correctly; they even installed some ventilation for our bathroom fan when they discovered it didn't have any. It's been about a week now and the extra insulation has made a huge difference!

Frequently Asked Questions

Got questions about insulation? We’ve got answers! Explore our FAQ section to learn more about insulation types, contractor selection, installation processes, and the energy-saving benefits of proper insulation.

  • How do I determine the right type of insulation for my property?

    Choosing the right insulation depends on several factors, including your property's location, climate, and existing structure. Different areas, such as attics, walls, and crawl spaces, may require different materials. We evaluate R-values, which measure insulation effectiveness, to recommend the most suitable option for your needs.
  • Can insulation be installed in an existing home without extensive renovations?

    Yes, it's often possible to add insulation with minimal disruption. We offer solutions like blown-in insulation for attics and walls. This method requires only small access holes.


    For crawl spaces, we can install insulation without major renovations. We assesse each property to determine the least invasive approach.

  • What are the advantages of foam insulation compared to fiberglass or cellulose?

    Foam insulation provides excellent air sealing properties. It expands to fill gaps and cracks, creating a tight barrier against air leaks.


    This type of insulation offers a higher R-value per inch compared to fiberglass or cellulose. It can also act as a moisture barrier, reducing the risk of mold and mildew.


    Foam insulation is particularly effective in hard-to-reach areas. It can conform to odd shapes and spaces, ensuring comprehensive coverage.

  • How does proper insulation contribute to energy efficiency in my home or business?

    Proper insulation reduces heat transfer between indoor and outdoor environments. This means less energy is needed to maintain comfortable temperatures.


    In South Bend Indiana's everchanging temperature, the right insulation is crucial because it prevents hot air from entering. This leads to lower heating and cooling costs year-round.


    Well-insulated buildings require less frequent HVAC system operation. This can extend the lifespan of your heating and cooling equipment.

  • Can new insulation help lower my Indiana Michigan Power electric and Nipsco gas bill?

    Absolutely! Proper insulation can lead to significant energy savings by reducing the need for heating and cooling. This not only lowers your utility bills that always seem to be going up in South Bend Indiana.


    Proper new insulation done by D&N Insulation can lower your gas bill from Nipsco and lower your electric bill from Indiana Michigan Power. 

  • What is involved in the process of insulation removal, and when is it necessary?

    Insulation removal may be necessary if existing insulation is damaged, moldy, or infested with pests. It's also required when upgrading to a more efficient insulation type.


    The process involves safely extracting old insulation materials. We use specialized equipment to ensure thorough removal without spreading contaminants.


    After removal, we clean and prepare the area for new insulation. This step can be  crucial for optimal performance of the new insulation material.

  • How much does the average insulation job cost?

    Costs vary based on the type of insulation you choose, the size and layout of your home, and any prep work needed (like old insulation removal or air sealing). On average, homeowners in South Bend might spend anywhere from $1,500 to $3,500 for typical attic or wall insulation projects. After we complete an on-site inspection, we’ll provide a detailed, transparent estimate that takes into account your specific needs and local St. Joseph County building requirements.

  • How do I choose an insulation contractor?

    Look for contractors with proper licensing and insurance, as well as extensive experience in South Bend’s climate. Read online reviews and ask for references from local customers. A reputable contractor will also be familiar with local building codes from St. Joseph and Elkhart County, offer written estimates, and communicate clearly about the scope of work and timelines. 


    Always ensure they perform a thorough inspection of your home before recommending any insulation solution.

  • How much does it cost to insulate a 1500 sq ft attic?

    The cost to insulate a 1,500 sq ft attic can vary widely depending on factors like insulation type (blown-in cellulose, fiberglass batts, or spray foam), attic accessibility, and any necessary prep or repair work. In South Bend, you can expect a range of approximately $1,500 to $5,000 for this size, though more complex projects could be higher. We’ll conduct an attic assessment to determine the most cost-effective approach that meets local energy efficiency standards and helps keep your home comfortable year-round.

  • How long does an insulation job take?

    The duration of an insulation project can vary based on the size of your home, the type of insulation being installed, and whether any old insulation needs to be removed first. Typically, most standard attic insulation jobs in South Bend can be completed within one to three days. Smaller projects may be wrapped up in a single day, while larger or more complex installations that involve mold remediation or significant structural work can take longer. 


    During our initial assessment, we’ll give you a clear timeframe so you know exactly what to expect.

  • What is the best type of insulation for an attic in South Bend, Indiana?

    In South Bend’s climate (which experiences cold, snowy winters and warm, humid summers), homeowners often find success with either blown-in cellulose or fiberglass batt insulation for attic spaces. These materials offer excellent thermal performance while remaining cost-effective. Spray foam insulation can also be a great solution if you’re looking for superior air-sealing properties—especially important in our region, where temperatures can swing drastically. Ultimately, the “best” type of insulation depends on factors like your attic’s layout, your budget, and the existing insulation conditions. We’ll work with you to choose a solution that balances energy efficiency with affordability, all while ensuring local building code compliance.
