"The company rep came out as scheduled and conducted a thorough and professional estimate for the added insulation. Then the installers came out and again did an outstanding job adding insulation to our attic. They worked well as a team and did an excellent job."

"Matthew did a thorough quote at my house shortly before Thanksgiving. Matthew was very professional, on-time and friendly. The technology was impressive as you could see the ?cold spots? around my attic space. I plan to execute the job after the holidays. I highly recommend Matthew and Insulation Commandos if you need any insulation related work."

"Reeds reinsulated our attic of 70 years. The former insulation had settled well below the rafters. The work crew vacuumed out the old, sealed around all openings to lights, fans, etc and then blew brand new fiberglass insulation to knee depth. We now have lofty, R-40 rated protection in a 2600 sq' house that heats evenly through out. Reeds will return to encapsulate our crawl space in one month!"

"We would recommend On the Spot. They removed all insulation in attic and basement and replaced it with the appropriate insulation for the house. They covered floors, had a dumpster and left no mess."

"Rep. checked entire system. He found several wires not connected properly and fixed this. He also made recommendations regarding the attachment of the panels to the rood that would provide more stability and leakproofing. The representative appeared to know what he was doing - much better than others, including the representative who was engaged by the roofer (who replaced our rood due to hail damage) to disconnect/connect the panels."

"Amazing job! My roof replacement was done in a timely manner & the crew cleaned up beautifully. My roof tech came back out after the installation to perform another inspection to make sure everything was installed correctly & there were no nails or trash left behind."

"These were the 3rd and 4th projects that we've had Shawn do for us. We were so pleased with his previous work on our kitchen remodel and bathroom addition, along with associated bedroom upgrades, that we contracted him again for these 2 additional projects. And we are currently working with him on a 5th project plus some miscellaneous tasks. His work, along with his crew, is outstanding.

They tiled our walk-in pantry and washroom pantry, along with upgrading all the woodwork and folding door. This brought those areas up to the standard they had achieved in the previous kitchen remodel, bathroom addition, and the multiple bedroom remodels.

The other project involved enlarging our screened-in porch to attach to the new bathroom addition and master bedroom, increasing our porch size from 192 to 324 square feet. I caused delays because of defective screening I ordered. Shawn was able to adapt to this schedule disruption.

You can't go wrong with Shawn. He has basically remodeled and expanded our entire house over the last 2-3 years, and we're moving outside to the back yard for future projects with him. You will get quality work with reasonable prices.

FAQs for batt, rolled or reflective insulation install or upgrade projects in Knoxville, TN

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.
