"I communicated with Ron directly and he was determined to solve our insulation problems. He had to remove drywall in our entranceway and add in insulation where there were large gaps and air was getting in. He had a worker drywall and patch up the wall. The drywall worker did an amazing job! 
Ron also fixed an ongoing issue we had in our garage ceiling that was causing our living room floor to be cold and drafty. He worked around our schedule and made multiple visits to our home to fix the issue. We are happy customers and happy to say that the problem is fixed. We were very pleased with Ron and his company and do recommend him highly.

"Courteous, diligent, professional and fair priced. Without reservation I would highly recommend Q-insulation. They installed rock wool insulation in all the ceilings and on the vertical attic walls in our historic brick victorian. They were prompt, on time and treated my home like it was their own. Thank you Valeria and the crew."

Insulation questions, answered by experts

If you’re moving wires, installing new wires, or installing new fixtures in the space you’re insulating, then you will need to hire a licensed electrician to do that portion of the job for you. However, if you just intend on replacing old insulation or adding new insulation over existing insulation, then you don’t need to hire one. Your insulation installer will work around wiring, fixtures, outlets, and switches, even if they’re installing fiberglass batts in the voids where wires run. However, you will need an electrician if you suspect a problem with your wiring during the insulation work.

Garage door insulation can last anywhere from 20 to 100 years depending on the type of insulation. Cellulose has the shortest lifespan coming in at between 20 and 30 years, while spray foam, mineral wool, and fiberglass can last between 80 and 100 years with proper maintenance. 

Humidity plays a role in how long more susceptible insulation materials—like fiberglass—last. Once fiberglass batts reach the 15-year mark, you'll need to routinely inspect your insulation to ensure that it is in mint order.

The best R-value for home insulation depends on where you live and where you’re installing the insulation. Your climate zone plays the biggest role in determining the correct R-value, so be sure to know which zone you live in when determining the R-value you need.

Insulation provides additional protection for your tankless water heater. Even if the unit is installed inside the house, it’s still a good idea to wrap the unit up with insulation batts, especially if you live in cold climates. For outdoor units, you can build an insulated box around the tankless water heater for freeze protection.

Depending on the item, several different materials are beneficial for long-term storage. Bubble wrap and plastic wrap help ensure delicate ceramics or furniture are safe and secure. High-quality moving boxes made of durable materials like plastic also help ensure the longevity of your storage, as cardboard will degrade faster over time.
