"Lou with Buckeye Wildlife was professional and very personable. We had the company out to clean out an attic in a 1959 home. The attic had been used for storage over the years and had old insulation that needed to be removed. Lou and his team removed all the trash and the old insulation. The attic is now "spotless" and ready for new insulation. I would highly recommend this company. They were thorough, and the price was very reasonable for the amount of work they did."

"I highly recommend Jason and Craig there at Mold Blasters. They did and absolute phenomenal job on reinforcing the wall in my crawl space that had begun to bow. They also encapsulated the crawl space which makes me feel so good and reassured that no mold will now form. I cannot say enough about this company. Jason is very honest and follows thru with what he says. You don't get that often these days. I would give more than 5 stars if I could. Good honest work. Thanks again Jason and Craigð  ¥"

"S7N created a sturdy and reliable work desk for my art room that can endure all of my crafting needs. The design was very thoughtful including storage space underneath and a matching shelf above. The desk is stained well and and I love having the matching set. I would definitely recommend S7N for anyone for household projects."

"Talkedto Steve at the home and garden show and set up an appointment for an estimate.
When he came out, he told me right up front that they were pretty backed up due
to the bad winter. I was fine with that and set a date that was good for both
of us to have the work done. They called the day before to remind me of the
appointment and showed up on time and did the work in one day. They did a great
job, cleaned up after themselves and you couldn?t even tell that they had
popped off the siding to drill the holes for the insulation.

Insulation questions, answered by experts

The best time to insulate a garage ceiling is when the weather is mild and dry. That means it shouldn’t be stormy, snowy, or raining, and the temperatures should be comfortable. Ideally, you’ll insulate your garage ceiling in the fall, before winter hits. Not only will you be the most comfortable, but you’ll also likely see the greatest energy savings heading into the colder weather with a newly insulated garage.

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.

Doubling the insulation in your home also doubles the R-value of said insulation. In other words, by adding more insulation, you can reduce the heat loss by half. Most homes benefit from increasing insulation. Older homes, in particular tend to have less insulation as is, so doubling your insulation could drastically reduce your energy bills, keep your home more comfortable, and take the strain off your HVAC system.

Durable materials suited for climate include aluminum for coastal areas or composite wood in varying environments for durability and minimal upkeep.

Bubble wrap is better for moving since it can be cut to size, whereas dish foam comes in precut sheets that are harder to manipulate. However, if you’re packing items like dishes, wine glasses, picture frames, or mirrors, dish foam will protect them better. Ensure you measure your box beforehand so you know what size dish foam to purchase.
