"We were looking for attic insulation and found Texas Pro during google search. We left a message on web site and few day later Nick Anderson contacted us and setup a time to explain the system. Nick scheduled a meeting, where he explained how his radiant barrier and how it worked compared to other insulation. We felt very confidant dealing with Nick. He is not your also ran salesperson. Nick is down to earth and explains the entire process without ever pressuring you to make a purchase. He even showed us his own electricity bills to show the difference. We opted to schedule the installation of the radiant. A time was set and workers arrived 05/31/25. They were on time and Stephon and Rasaun got to work. It took about 5 hrs and hour to install and clean up. Stephon showed us the work and explained how it was installed. It was all professionally done and looked very neat and clean. The workers took great care to prevent any damage to ceiling. It was a phenomenal job by Stephon and Ra"

FAQs for blown in insulation install or upgrade projects in San Antonio, TX

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.
