ABI LLC is committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty, and personal responsibility. Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers' interests, and make their concerns the basis of our business.

"We chose ABI because we were comfortable with their assessment, quote details, and ability to answer our questions thoroughly. We went with polyiso boards and cellulose as the materials. The price was very fair. The day they did the work, with Flo and Carlos onsite and part of the crew, they were focused, professional, friendly, and careful with our home and belongings. Any hiccups along the way were problem-solved and dealt with immediately. They not only left the inside clean, vacuuming after they removed the runners they brought, but made sure to check the outside of the house and swept the driveway for any small debris. The final check included a walk around the outside of the house. We knew they had to remove the siding to drill the holes to blow in the cellulose, but you would never know that the siding had been disturbed. We would not hesitate to recommend this company to anyone else looking for a fair and honest home insulation company! "

We specialize in wall and floor covering, such as painting, tiling, hardwood floor and finish basements. We have been in this industry for over 60 years my background is interior design were it comes handy when choosing materials and colors. We are owner operated business.

"We are so happy that we chose Chakar Construction. Ramy is a great guy - attentive, communicative, honest, and does really excellent work. He took great care to advise us on what would look best and cost the least, and was quick to let us know about any obstacles he encountered (since our house is relatively old) and our options to best circumvent them. He was flexible with his schedule to meet the deadline we requested and went the extra mile to make sure our floors, walls, and new carpet were finished up to his high standard. We couldn't be happier with how the work came out, and Ramy was an absolute pleasure to work with. We would happily work with him in the future and readily recommend his services to anyone."

FAQs for blown in insulation install or upgrade projects in Nashua, NH

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.
