"The receptionist took the call and told me to expect a all from the technician. He called back immediately to set up an appointment. Greg was quick and professional. I plan to hire them again if I need anything. I went into their office to pay the bill and the receptionist was very helpful and pleasant."

"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."

"Fantastic. Redeemer filled all of the voids under the entire driveway - literally at least 1/3 of the driveway had zero support underneath it because the ground had washed away. The Whole driveway is now level and all the cracks are repaired."

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.

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise. 

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

The most obvious con of injection foam is the cost. It’s much more expensive to install than fiberglass or spray foam, but it may be your only option (unless you want to remove entire walls around the home). Another con is that it involves drilling into existing material, which has to be repaired after the foam is injected. Some injection foams are made from products that aren’t environmentally friendly, and improper installation can lead to trapped moisture, which can lead to expensive mold remediation down the road. 

Insulating a detached garage won't reduce your home's heating or cooling bills—and insulating an attached garage will only have a small effect on your home's energy efficiency. However, insulating an attached garage can reduce the transfer of heating and cooling to and from the outdoors, which can reduce the amount of energy your home needs to stay comfortable. Also, having an insulated garage is just more pleasant. Balance the cost of insulating your garage with how you'll use the space to determine if the project is worth it.
