"We had insulation installed a week earlier by Koala. During the insulation, Jasper (insulator) suggested another area that we might consider installing blown-in insulation. We agreed and the second job was performed on Friday, the 24th. Jasper and Richard were on time, the insulation project was well done and they left the area very clean. Would use them again."

"I would just like to thank this company for the work they did in my home! Iâ m very late writing my review but I wanted to see how different my home felt since having this service. Complete Home Solutions serviced my house on November 20, 2020, The crew consisted of Brad, Jason, Aaron and John B. There was another individual who did my drywall work, but I didnâ t get his name. There are no words to describe how much I appreciate your professionalism, knowledge, experience, cleanliness, kindness...etc. You guys did such a wonderful job! Since getting insulation put in my sonâ s room, I can feel the difference, a huge difference!! Also, I would like to thank Noah for the first initial visit and explaining to me in detail about the difference in the products. If youâ re looking for a company to provide service to your home, thereâ s no need to look any further! Iâ m looking forward to hiring them again, for my crawl space."

Insulation questions, answered by experts

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

Yes, insulating your cold water pipes is a great way to prevent condensation. When warm, humid air meets cold pipes, condensation forms, which can drip and cause moisture issues in your home. Pipe insulation acts as a barrier between the warm air and the cold pipes, keeping condensation at bay and helping you avoid potential problems like mold or structural damage.

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.

The life span of fiberglass insulation can be as long as 80 to 100 years, but because of changing building codes, it’s best to get your insulation checked every 10 to 15 years. Signs of degrading fiberglass insulation include bits of batts on the floor or batts detached from frames. Having optimal, healthy insulation in your home will improve its energy efficiency, lowering your monthly bills.

Yes, you should add an insulative cover to outdoor water spigots in the winter for better protection against freezing. Make sure to use waterproof insulating material—something like a towel or old shirt can actually make the faucet more prone to freezing when the material soaks up rain or snow.
