"They were very professional and did an amazing job. Miguel and his crew removed all of the old blown in insulation that was below the recommended depth. Fixed leaks and filled in spaces that were letting in the cold and blow in new fiberglass insulation to the proper depth. Immediately we felt the difference in our home. I'd highly recommend them."

"Since 7/2025 I knew we needed insulation blown into our less than 1300 SF 1973 built home. Got a quote for over $5000, left messages at many more and some didn’t even show up or return my call. On 12/16/2025 I called Angi list and was told someone would be calling me back soon(bet they want!) Well they did and I spoke Nick Martin of Martin Home Solutions and gave me a quote that I was able to pay (We are old!) and he and Jason Farmer came to our home last evening 12/17/2025!!! (Ready To Work!) We were so impressed by Nick’s honesty, open communication and work ethic. We were so very happy to know that we can survive this winter financially with adequate insulation in our attic. Call Angi List today if you are searching for someone for your attic needs, Martins Home Solutions will not disappoint."

He did everything I asked and even gave me pictures of before and after ... I would recommend Tri-Star Wildlife to anyone ... you won't regret it. He saved me money and did more than what the other company's were asking. Mark Raith"

"Was most impressed rep. Enjoyed our conversation. He was clear in describing processes; forthcoming on costs, educational on differences in products. Under other circumstances, ie, remaining in this house, would undertake insulation."

Insulation questions, answered by experts

One of the clearest signs that your insulation isn’t working as well as it should be is a noticeable difference in temperature throughout your home. One room might feel icy while another is hot as Arizona—this indicates that some parts of your home are either retaining or losing heat more than others. Additionally, a sudden increase in your energy bills, evidence of pests or rodents, or evident water damage are other signals that warrant a thorough inspection of your insulation and potential replacement.

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.

R-value stands for resistance value and is a number assigned to insulation that states how good the insulation is at heat transference (insulation). The R-value of injection foam is around 4 which homeowners will be happy to know is actually quite good. Another benefit of injection foam versus fiberglass foam is that the colder it gets, the more injection foam retains its resistance properties, whereas fiberglass tends to lose its efficiency in colder temperatures.

The time required for insulation installation can range from a few hours to a few days, with most projects taking 1-3 days to complete. The final duration depends on the project's size and complexity, the area size, and the type of insulation being installed.

Yes, insulating ductwork in a crawl space is a worthwhile investment, especially if you live in a colder climate or run your air conditioning for most of the year. Uninsulated ducts can lose up to 30% of their heating and cooling efficiency, which can significantly impact your electricity bill. The project is a relatively small investment and typically only takes a few hours. It's a particularly simple add-on if you are already hiring someone to insulate the entire crawl space. An added benefit is that insulated ducts put off less hot or cold air, making them less attractive to pests.
