Holes cut in the clapboard were not replaced correctly, (not flush with siding). Holes were not sealed properly. I was told the fiberglass blown in insulation was cleaned up from the yard. No cleaning up was done. I made the mistake of paying in full prior to checking the work because it was...

The door was not hung properly, had to come back to reinstall it. The owner was understanding, completed the job. While the door was rehung properly, the foam insulation was over-applied to leak out everywhere creating a mess and stains.

I scheduled a time with Brian Gordon to come give me a quote and he arrived promptly on time. His quote for vacuuming out the old spray insulation and blowing in new cellulose insulation into my attic was a very fair price. He and his team did a great job. I would recommend him to anyone.

Insulation questions, answered by experts

When temperatures are too cold, it can keep ice from melting, and products like ice melt and rock salt are ineffective. Water turns to ice in temperatures below 32 degrees Fahrenheit. Ice melts on its own when temperatures reach above 32 degrees Fahrenheit.

Ice melt loses effectiveness in temperatures below -25 degrees Fahrenheit, and rock salt works in temperatures 5 degrees Fahrenheit and warmer.

Mineral wool has an excellent life expectancy of up to 50 years, provided it's kept dry and free of pests. Compared to fiberglass, with a life span of 20 to 30 years, mineral wool stacks up well for long-term cost savings. Sheep wool maintains a similar life span to fiberglass, while estimates for hemp wool insulation life expectancies are all over the board, ranging anywhere from 20 to 100 years.

The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.

The most affordable way to insulate a garage involves choosing cost-effective materials like fiberglass, which comes in batts or rolls and is relatively easy to install. You can often install this type of insulation without needing to add drywall, which helps reduce costs. While a DIY approach might seem cheapest, hiring a professional installer can be highly cost-effective. Experts can accurately determine your garage's specific insulation needs and ensure the best results for your investment, often using batt insulation for the bulk of the project.

DIY installation is not recommended, as professionals ensure even distribution, proper sealing, and compliance with building codes.
