"The crew worked quickly and efficiently to replace and upgrade the fiberglass batts in our basement and crawl space. I’m pleased with the outcome. (I put in even more wire supports afterwards — to secure the insulation between the joists — but that’s just my OCD.) It was a relatively small job for this company and I thought the cost was fair."

"Do not use Perfect Wall. I got the insulation done 4 months ago and still have not gotten my rebate because of all the incorrectly filled out forms. Moreover, when I have tried to reach back out to them for help with corrections they have not been responsive. They made it seem like getting the rebate would be easy and it has been a huge hassle, thanks to the way they have handled it."

FAQs for blown in insulation install or upgrade projects in Killingworth, CT

Many major home improvement retailers offer free machine rentals when you purchase a minimum quantity of insulation material, often 20 to 30 bags. These promotions vary by location and season, so calling ahead to confirm current offers is recommended. Be sure to understand any time limitations that apply to these free rentals, as they may restrict you to a specific return window, often 24 hours from checkout.

For most residential attics under 1,500 square feet, a standard consumer-grade blower available at rental centers will provide adequate performance. Larger spaces or projects requiring greater insulation depth may benefit from higher-capacity equipment. 

When consulting with the rental provider, mention your attic's square footage, desired insulation depth, and accessibility conditions to receive appropriate equipment recommendations for your specific situation.

DIY installation saves between $160 and $560 in labor costs for standard attic installations requiring four to eight hours of work. These savings must be weighed against equipment rental fees of $50 to $210 per day and the value of your personal time. For more complex installations like wall insulation, which can require 20+ hours of professional labor (costing $800 or more), the potential savings increase substantially, though so does the project complexity.

While there's a learning curve, most homeowners can master the basics with some practice. Key techniques include maintaining consistent material flow into the hopper, controlling hose direction effectively, and preventing clogs in the system. 

Starting in less visible areas allows you to refine your technique before moving to more prominent spaces. Thoroughly reviewing the equipment manual and watching instructional videos beforehand significantly improves first-time success rates.

Standard rental periods provide 24 hours of use, though specific terms vary by provider. Some locations calculate this as a calendar day, while others track a full 24-hour period from checkout time. Clarify the exact return deadline when renting, and plan your project timeline accordingly. Late returns often incur additional daily charges at the full rental rate, which can quickly increase your project cost if not managed carefully.
