"The provider was extremely professional.  He did two chimney's although I had originally only indicated service for 1 as well as did the tuck pointing for the one fireplace. 
He walked me through in detailed all of the steps and reviewed with me all of the changes that they made and the service and additional costs were clearly indicated prior to work being completed. 
After cleaning the chimney they clean up their mess and the one chimney that was in the basement had concrete dust from a sump pump I had put in and they cleaned that up too. 
Additionally, he went back and corrected something he did not find to his standard even though I don't know that I would have noticed. 
I would definitely recommended him to others.

"We called for a quote and Mindy came the same day to review our spaces and provide a price. After rain cancelled our first installation, the second date was dry and the team of three guys were on time. They reviewed where we wanted the tubes and took their time with the installation. The addition of natural light makes a huge difference and we are very satisfied with the product and the installation."

"The estimate and the people doing it was good. They knew what they were talking about and took their time. They said the work would start early February before they can start, which is fine its no rush. But we would appreciate if they could just give us a date. My wife has chased them down and they haven't gotten back to her. Just keep us in the loop, we shouldn't have to chase them down. We understand if the weather delayed or a set back. Its not hard to make a call or send an email."

"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.
