"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

Yes, an automatic pool cover retains heat. It can act as a thermal blanket because the heavy vinyl traps heat underneath, keeping the water warmer than if there wasn’t a cover. Keeping the pool cover closed when the pool’s not in use can also help reduce water utilities and save on pool chemical costs because there won’t be as much evaporation.

Using plastic shrink film over the window will cut down on drafts, which makes the air inside your home feel warmer. Plastic shrink film doesn’t quite have the insulative properties of a new window or of adding insulation inside the window jamb, but it will help. Plus, it’s a cost-effective solution to keeping your home warmer.

Insulating your basement walls offers numerous advantages that make the project well worth it. By adding insulation, you can reduce the chances of moisture damage to the house's structure and lower the odds of mold growth. You'll also add comfort to the space by reducing temperature swings and increasing your home's energy efficiency, potentially reducing your energy bills to earn your investment back.

Generally, the cost of ice dam removal is not covered by homeowners insurance because it is often considered preventable maintenance. However, the damage caused by ice dams is frequently covered. Depending on your policy, this can include interior water damage, roof collapses, and damage to shingles. Coverage for personal belongings affected by leaks may vary. It is important to check your policy details or contact your insurer to confirm what your plan covers. Keep in mind that any damage resulting from a DIY attempt to remove an ice dam will likely not be covered.

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.
