Francisco installed 100â of stairs on a steep hill, shaping railroad ties to make the stairs wind down the hill. He also installed mulch and planted new shrubs. He is an outstanding professional who does beautiful work in a timely manner for a fair price. I highly recommend him.

Doorbell Installation questions, answered by experts

Cellular shades, also known as honeycomb shades, are the most energy-efficient and insulating window treatments. Their honeycomb structure is made of soft fabric that forms layered cell pockets. These pockets trap air, creating a thermal barrier that reduces heat loss in the winter and blocks heat gain in the summer. For even greater insulation, consider double- or triple-cell varieties. Side-tracked cellular shades, which seal the edges of the window frame, can further minimize air leaks and maximize energy efficiency.

One of the clearest signs that your insulation isn’t working as well as it should be is a noticeable difference in temperature throughout your home. One room might feel icy while another is hot as Arizona—this indicates that some parts of your home are either retaining or losing heat more than others. Additionally, a sudden increase in your energy bills, evidence of pests or rodents, or evident water damage are other signals that warrant a thorough inspection of your insulation and potential replacement.

It is usually possible to install insulation yourself, but it’s often better to hire an insulation professional. An experienced insulation pro can determine which type of insulation is best for your space and the R-value get the most value and comfort in your home. Certain types of insulation can cause skin, eye, and lung irritation, and a professional will have the equipment necessary to keep themselves safe and limit the effect on your indoor air quality after the installation. Certain types of insulation—like blown-in and loose-fill insulation—demand a professional for proper functionality and safe installation.

The primary reason that insulation saves you money over time is that it reduces your energy bills by making your home more energy efficient. A crucial part of an insulation system is a properly installed vapor barrier. Local building codes dictate whether your insulation requires a vapor barrier based on the type installed. While some high-quality wool insulation may not technically need a vapor barrier, most municipalities still require one to meet code.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation:

If the insulation is over 15 years old
If the insulation is wet or moldy
If it is vermiculite insulation
If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.
