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! "

"Our heater stopped functioning on Nov 27, 2023 and we called Petro who had done the maintenance on it before and replaced a motor two years ago. They were responsive and a technician came two days later. He worked for 3 hours without explaining what the problem was. Then said he needed to replace the motor. He fixed the problem and left without much explanation. Two days later a bill of $2500 came via email. No explanation, no break-down. I called 4 times over the last 20 days, spoke to 4 different reps and was promised that a supervisor will contact me with the bill details. Nothing happened. Irresponsible customer service and unprofessional behavior. They show all the symptoms of big, bureaucratic, and indifferent service company. I would not recommend Petro if you have options of more personalized services."

FAQs for batt, rolled or reflective insulation install or upgrade projects in Nashua, NH

Batt insulation excels in vertical installations because it remains firmly in place and delivers consistent thermal performance. Blown-in insulation performs exceptionally in spaces such as attics, efficiently filling gaps in irregular areas. 

Employing both insulation types according to their strengths enhances your home’s overall energy efficiency and comfort by providing a tailored solution for every space.

Start by measuring the square footage of the space, then match that area with the insulation thickness you need to hit your target R-value. Add a buffer for waste and odd-shaped spots so every cavity is covered. 

Once you have a rough count, run it past a local insulation pro—their on-site advice will fine-tune the numbers and help you avoid costly miscalculations.

Old insulation that is dry, intact, and mold-free does not require removal before adding new insulation; stacking new insulation over it maintains effective thermal performance and boosts energy efficiency. 

If the insulation is damp, moldy, or deteriorated, removal is necessary to eliminate health risks and ensure maximum effectiveness of the new layer. A professional insulation contractor will assess your situation and recommend the most effective solution.

Installing insulation in an average-sized home using batts or boards requires five to 12 hours. Using spray foam or blown-in insulation requires two to five hours. These timeframes are determined by the area’s size, accessibility, and whether old insulation must be removed. 

Complex projects and hard-to-reach spaces demand extra time. Hiring an experienced insulation professional ensures that the installation is completed efficiently and correctly.

Insulation is measured by R-value, which defines how effectively it resists heat flow. A higher R-value provides superior thermal resistance, ensuring your home remains warm in winter and cool in summer. 

Choosing the correct R-value is essential for maximizing energy efficiency and comfort, and it directly impacts long-term utility savings. Professional guidance determines the optimal R-value for your specific climate.
