"Bottom line: I would hire this company again. Koala Insulation came and inspected my attic spaces with a infrared scanning tool. They looked at the level of insulation and found areas where the heat was penetrating more. They recommended specific actions and gave me a number of quoted options on the spot. I was then able to book the service within days of the initial visit. The technicians came and performed the service professionally and made sure to involve me where needed. I would hire them again."

"I hired Be My Guest to do a yard clean-up for my house before it went on the market. I had contacted previous companies for estimates and received ridiculous quotes of $1100-1600 to clean my front and back yard which included trimming bushes and tree limbs, raking leaves and spreading mulch that I purchased. Fernando, the owner of Be My Guest, quoted me $300. Deal! As I shared my to-do list of projects to prepare my house to list, I found out that the companies abilities extended past yard work. I ended up hiring them for $1100 to clean the yard, paint the house and front door, replace the expansion boards in the driveway and walkway with cement, fix the cracks along the cement foundation from the house settling and paint the back porch, stain the cement floor/steps, paint the garage and stain the floor. I also ended up getting full sod for the back yard, which cost met $850 total including labor. Other companies were quoting me $1100-1300 for a back yard that is part of a .11 acre total property! The projects soon moved inside and I hired them the paint the baseboards and trim, paint one room, replace the flooring in the kitchen and bathrooms, fix laminate pieces in the current flooring and fix moulding at the top of my kitchen and bathroom closets. The work took over a week to complete and time for completion was underestimated a couple of times, but I was extremely pleased with the work overall. My house is now move-in ready and the realtors who visited said it looked like a model home. Exactly what I wanted! I have a list of projects to begin at the new house and have already scheduled Fernando to start next week, including yard work and new fencing that will be over 400 feet. I often get mistaken as a naive female who doesn't do her research on projects and costs and some contractors/owners I've contacted in the past to get estimates see dollar signs when I answer the door. Fernando didn't treat me that way and it put him above the others. I highly recommend Be My Guest and Fernando and his team. He was fair, open to changes or add-ons to your list without gouging you price wise and they do great work."

Insulation questions, answered by experts

Drywall insulation costs around $1,800, on average, but prices can range from $500 to $4,500, depending on a few different factors. The following things are important considerations to make when pricing out your insulation project:

  • Square footage of insulation

  • Type of insulation 

  • Climate in your area and the insulation R-value required

  • Whether or not your walls are already finished

  • Accessibility of the area 

  • Whether or not you need old insulation removed first

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.

Closed-cell spray foam insulation itself serves as a vapor barrier (or vapor retarder). However, you may need to install a vapor barrier if you have open-cell spray foam insulation. When in doubt, work with a professional insulation contractor, as they can provide more detail about the specific needs of your home in your climate.

Yes, insulating ductwork in a crawl space is a worthwhile investment, especially if you live in a colder climate or run your air conditioning for most of the year. Uninsulated ducts can lose up to 30% of their heating and cooling efficiency, which can significantly impact your electricity bill. The project is a relatively small investment and typically only takes a few hours. It's a particularly simple add-on if you are already hiring someone to insulate the entire crawl space. An added benefit is that insulated ducts put off less hot or cold air, making them less attractive to pests.

While carpet over carpet may provide some additional insulation and soundproofing benefits, it's not as effective as other methods. Layering carpets can add a modest buffer against noise and temperature fluctuations, but it's limited compared to installing thicker carpet padding or using specialized soundproofing materials. For optimal floor insulation and soundproofing, consider alternative solutions tailored to your specific needs and budget, such as adding additional padding or soundproofing underlayments beneath the carpet.
