"First : I was concerned with the negative reviews .So i contacted them and asked for an explanation ..I was satisfied with what they had to say ..and I thought their honesty was refreshing 
My electric bills were 2 times more than my neighbors 
2) i scheduled a home assessment .. and even though we had a schedule change communictaion was always good 
3) after assessment they suggested $5000 plus in upgrades , but gave no pressure to use their service ..I researched the cost of DYI vs. using them and consulted with Ameren to advise ..I decided Peterson was about 25% more than doing the job myself and was satisfied that was worth not doing the job myself 
4) but I saved a little by doing the easiest job myself ...Insulating  my open basement rim joists 
5) The workers were quick /clean/courteous/and professional ...THEY CLEANED AFTER THEMSELVES !!!
6) Work was complete and I am 100% satisfied 
I have waited a few months to see if my energy costs went down (before reviewing) ... It is hard to accurately quantify savings ...but in comparison to neighbors it seems to have a 35-40% reduction in electric use during warmer months ...That said I would still have a few years to break even with  cost of insulation ...BUT the comfort level in our house was well worth the costs ..We used to have a warm upstairs and used a a/c window unit to keep up ..We no longer need window a/c and everyone is happier and house temps are more moderate on each level 
Final assessment : It was expensive but well worth it and Peterson was a very good provider of advise and services

"The entire experience with Josh Dunn and his team went extremely well. I had another contractor over to look at the space, and his estimate was 30k, he really had no good ideas for what to do with the originally awkward layout, and he advised that I should move my two kids (ages 1 and 4) out of the upstairs during the remodel. Josh walked in and immediately envisioned what to do with the space and came in with a lower estimate. He and Mike worked meticulously, controlled dust, and cleaned up every afternoon before they left. They did any and all sawing and tile-cutting outside. My baby took naps in the basement, but both my kids slept at night in their own beds in their rooms, and I never worried about dust. Josh and Mike are polite and professional, keep you informed of the process, and are also very good at what they do. No drywall seam is visible, no tile is crooked, and the paint job is extremely clean. Our remodel was extensive enough that we needed city (Richmond Heights) permits, and that required that separate electricians and plumbers do that work and that everything (electrical, plumbing, building) be inspected two times. All of that slowed things down, but Josh and Mike communicated so well and kept everything so neat that I had no complaints. They also subcontracted out to workers who were as nice and professional as they are. I will have Dunn Home Improvements do any home remodeling project, large or small, that arises in the future."

"We are very pleased - the bathroom looks great! Workers were always professional, helpful, courteous, friendly. Always sought our input. Did extras, like rerouting air duct so we could have our recessed medicine cabinets. Included plumbing, electrical, framing, relocated window (outdoor siding redone), widening outer wall for increased insulation for pipes. Fixed access hole in basement ceiling and installed water shut off valve to bathroom. Installed extra electrical outlet for wife's hair dryer and a backsplash. Even fixed a hole in wall of another bathroom and rehung towel bar as a courtesy. Highly recommend."

FAQs for batt, rolled or reflective insulation install or upgrade projects in Renault, IL

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.
