"The whole team exudes professionalism and good-will. Marc was very transparent with their very competitive pricing, and always looked to provide the most relevant information to me as the home owner, rather than up-selling me like countless others have done. The techs were extremely quick and thorough, always kept me updated on the decisions they made, and went out of their way to make sure everything was above and beyond. Overall, I'm extremely pleased with the service and will go to Affordable Insulation for any other future endeavors."

"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

Each of the three types of wool insulation has particular disadvantages. While their R-value is higher, they all cost more than fiberglass versions. Installing mineral wool and sheep wool requires protective gear. Because of its vulnerability to insects, chemicals are used in its production. Hemp wool is more costly to install than other types because additional tools and labor are involved.

Radiant barriers and insulation serve different purposes, so one is not inherently better than the other. Radiant barriers reflect radiant heat, helping keep spaces cool, especially in hot climates, while insulation slows heat transfer through conduction. For optimal energy efficiency, it’s best to use both together. 

Radiant barriers can enhance the performance of insulation by preventing heat gain in the summer and heat loss in the winter. The choice between them depends on specific climate conditions and the building’s design requirements.

On it own, aluminum siding has a relatively low insulation value (also called R-value); aluminum siding has an R-value of 0.61. However, you can purchase insulated aluminum siding to increase the R-value to between 2 and 5. You can also install additional insulation within your walls to help maintain temperatures within your home. On average, insulation costs $1,825 to install throughout the typical home.

Yes, professionals install and upgrade insulation for all home or business areas.

For a DIY solution to protect an outdoor faucet from freezing, you can craft a cover using spare rags, a durable plastic bag, and duct tape. However, be aware that this method may not be as effective as a store-bought cover. Fabric like rags or old towels can absorb water, which could freeze and cause problems. While a DIY cover can work as a temporary stopgap, a proper outdoor faucet cover is inexpensive (often $5 or less), easy to install, and readily available, making it the recommended long-term solution.
