"Standard Insulating Company sent David E to our house to a**** a problem we were having with hot spots in certain areas. David was up front with his assessment and explained everything in a way we were able to understand. The quote he emailed us was surprisingly reasonable with no hidden fees or surprises. We chose to have our insulation capped as well as radiant barrier installed. The work was scheduled less than a week later and the crew was professional, knowledgable, quick, efficient and kept the whole work area clean. I highly recommend Standard Insulating Company to anyone looking to have any type of insulation work done."

"Did not do work, but pricing was competitive with everyone else.  Invoice got lost in junk e-mail, so did not think I ever received invoice, but I found it a month or so after job was completed again.  If\when I have another job will call All Foam and make sure Invoice doesn't get lost in junk e-mail!

"Outstanding! Mario and his workers did a fantastic job! They removed all insulation. They sanded off all wood and treated with a solution to kill any residual mold. They placed new insulation. They encapsulated the whole crawl space and placed a dehumidifier. I felt very confident that the job was "done right". The whole organization very professional."

"Wayne and his crew did a spectacular job, at a very fair price. What began as a simple dryer vent job, became a critically important HVAC-related repair, after his willingness to check on our mold and odor issue from our primary air conditioning unit. Net/net: He discovered our problem was with mold and retained water in flex duct work that had not been properly checked and cleaned. He provided us with a comprehensive quote, and quickly got us on his schedule, even though it meant they had to work on a Saturday. He and his crew arrived on time (in fact, 15 minutes before promised) and in one day changed out all duct work. He also returned to our home the next week, to verify everything was properly installed and working, and "tweaked" a few ducts that needed adjustments. Wayne knows his "stuff" and advised on cost-effective solutions (at far fewer dollars) to save on addressing one remaining issue. Lastly, when we had concerns with a faint odor (not caused by their work) he immediately returned the next morning, to ensure everything was working properly. We highly recommend Lindsay's Air Care -- excellent and prompt, expert service. Very fair price, knowledgeable and friendly, willing to explain all work, quick to follow up to ensure we were completely satisfied and that the work was done correctly in all respects."

"John (the owner) emailed me promptly. He provided me a quote with a clear explanation of what is covered. At the end I did not use his company because I needed the job done sooner than he could schedule."

Insulation questions, answered by experts

The primary downside of radiant barriers is their limited effectiveness in cold climates. They are designed to reflect radiant heat, making them less beneficial in cooler conditions where heat retention is more important. 

Radiant barriers require proper installation to maximize effectiveness. Incorrect placement can lead to minimal benefits. They also do not provide insulation, meaning they should be used in conjunction with traditional insulation for optimal energy efficiency. 

The cost of installing spray foam insulation is $2,760 on average, but this cost can be as low as $650 or as high as $7,700. The main cost factor is the size of the insulated area and the type of spray foam insulation. 

Polyurethane spray foam costs between $0.44 and $1.50 per board foot, where a board foot is equal to the volume of a one-foot length of a board. More expensive options, like soybean or vegetable oil spray foam, range from $1.50 to $3.00 per board foot.

Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.

Ductwork should be wrapped in insulation in certain locations. This includes unconditioned interior parts of the home, such as attics, crawl spaces, basement ceilings, and between floors. Duct joints should also be insulated since they're more likely to leak air than other parts of your system. Building codes in some areas also require ductwork to be insulated.
