"I know of no other contractor who has total customer satisfaction as his top priority like Mr. Flanagan does. He is absolutely the best.
My basement sustained ankle-deep water as the result of an outdoor basement stairwell drain that violently backed up because its circa-1951 drain line led to the street storm sewer (by design). That sewer was overcome with water during a storm in the summer of 2010 that featured a tornado in my western-suburbs area. Soon after pumping the water out of my basement with a mobile pump, the mess prompted me to (once again*) call Mr. Flanagan (*His crawlspace crew had done a beautiful job finishing my dirt-floor crawlspace with a concrete floor and wall insulation a couple of years earlier).
After the basement waterproofing project described in this review was complete, however, I was disappointed with the workmanship: The concrete work looked less-than-professional (out-of-flush with sump flange and the stairwell drain, plus way too many swirl marks and splattering) in the stairwell and basement's appearance areas. In short, it just didn't look like his business's flawless concrete job that was done in my crawlspace just years earlier.
Mr. Flanagan agreed. With no questions asked, he immediately had a different crew come to my home, tear out all of the previously laid concrete and drain lines and replace it with the workmanship that he would expect his crews to use in their own homes. The re-do of the project at least had met my high expectations for its cosmetics. And, of course, I hoped it was a sufficient waterproofing solution for my basement.
Fast forward just a few short years. Affter having perhaps sustaining that 100-year event with the Chicago-area rain storm of April 17-18, 2012, while my neighbors are pumping water out of their basements, mine remains bone dry. Thank you Mr. Flanagan and Crawlspace / Basement Waterproofing Solutions for a job (design and installation) well done. Your basement waterproofing solution indeed deserves an A+.

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Insulation questions, answered by experts

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

Blown-in insulation works, but only for unfinished attics. Also, it isn’t the longest-lasting nor the most effective option. For better options, look into spray foam insulation or natural fiber batts. They typically have a longer lifespan, better heat resistance, and stronger sound-proof abilities. Spray foam insulation costs about $1.25 to $1.50 per square foot, but can go up to more than $4 per square foot. Fiber batt pricing varies depending on the material.

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.

The primary reason that insulation saves you money over time is that it reduces your energy bills by making your home more energy efficient. A crucial part of an insulation system is a properly installed vapor barrier. Local building codes dictate whether your insulation requires a vapor barrier based on the type installed. While some high-quality wool insulation may not technically need a vapor barrier, most municipalities still require one to meet code.

You can purchase bags of cellulose and loose-fill fiberglass blown-in insulation from the same local home improvement store where you rent your blower. If you want to use rock wool insulation, you may need to special order it.
