"Fast work. Great communication up until trying to communicate with project manager. Was told everything would be completed within two days. The roof was done in one which was awesome, but I am still waiting on gutters a week later and won't be given a day/time for them. Just keep being told "early next week" or "tomorrow". Sales portion and inspection went great. Fantastic everything up until the install."

"I recently had my roof replaced by Cox Roofing LLC in , Toledo Ohio and I couldn't be happier with the results. The project was actually completed about a month ago, but I got busy and completely forgot to leave a review! Now that I have a moment, I wanted to make sure they get the credit they deserve. Their team was professional, efficient, and the quality of the work is top-notch. If you?re in the Toledo Ohio and need roofing services, I highly recommend them!"

"The salesperson who came out was very nice and professional - however, he did not tell me that I needed to have everything in the basement 3 feet from the walls.  This caused us to scramble on the day of installation and i'm certain that this made it more difficult for the installers as well.  Additionally, no one had warned me of how strong the smell would be initially and I had to scramble a bit to get my very young family out of the house to avoid it and/or off-gassing.  The installers arrived on time and were ready to roll.  They did an excellent job insulating the rim joists and did a pretty good job of cleaning up.  There were some spots where I had to scrape the insulation off of the floor and wall.  Overall, I would recommend them for small jobs such as this.

Insulation FAQs, answered by experts

Installing sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.

When it comes to fiberglass insulation versus foam board, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass.

While freezing pipes are less of a concern in warmer climates, pipe insulation can still be beneficial because it helps prevent condensation on cold water pipes, reducing the risk of moisture-related issues like mold growth. It also helps maintain water temperature, reducing the energy needed to heat and cool the water, which can ultimately lower your utility bills.

Yes, you can use too much bubble wrap. If you overdo it with the wrapping, it can strain the top of your box and break open the taped seal, risking the chance that the contents of the box could fall out or break. Use enough wrapping to fully cover your item without compromising the security of your box.

While insulation is required for all exterior walls in a house, it is not typically required for interior walls. Local and state building codes mandate that new construction homes have adequate insulation in exterior walls and ceilings to suit the local climate.

However, there are several benefits to adding insulation to interior walls. It is excellent for sound-dampening between rooms and can help with temperature control by maintaining a regulated temperature in specific rooms and lowering heat transfer between adjacent areas. Insulating interior walls can also contribute to the overall energy efficiency of your home.
