If your home feels drafty, unevenly heated or cooled, or harder to keep comfortable throughout the year, the cause may be related to air leaks, insulation gaps, moisture issues, or hidden performance problems. This FAQ page covers common homeowner questions about comfort, energy efficiency, weatherization, insulation, and home diagnostics so you can better understand what may be affecting your home. If you want expert guidance based on your specific home, learn more about our home energy audit or schedule service.

Home Comfort and Temperature FAQs
Why are my floors so cold in the winter time?
Cold floors are often caused by air leaks and missing insulation in the crawl space or basement below your home. When outside air enters through gaps around rim joists, floor penetrations, or unsealed areas, that cold air affects the floors above it. Proper air sealing and insulation can help block that airflow and improve comfort. If cold floors are a recurring problem, it may be worth exploring your crawl space insulation options or scheduling a home energy audit to find the source.
Why are some rooms in my house hotter than others?
Temperature differences between rooms are often caused by a combination of air leakage, insulation gaps, duct issues, and HVAC performance. Rooms farther from your system may receive less conditioned air, especially if ducts are leaking or attic insulation is underperforming. Air sealing and insulation improvements can help reduce those swings and make your home feel more balanced. Learn more about air sealing and duct sealing.
Why should I worry about my crawlspace if its not connected to my house?
Even if you do not spend time in your crawl space, it can still affect the air, temperature, and moisture levels inside your home. Air from an untreated crawl space can move upward through gaps in the floor system, bringing in humidity, odors, and airborne contaminants. Moisture issues below the home can also contribute to comfort problems and long-term material damage. A properly treated crawl space helps protect both your home and your indoor environment. See our crawl space services for more information.
Energy Efficiency and Weatherization FAQs
How will adding more insulation lower my energy usage?
Insulation works best when it is paired with air sealing. On its own, insulation helps slow heat transfer, but if your home still has major air leaks, conditioned air can continue escaping. When the right insulation levels are combined with proper sealing, your home can hold temperatures more effectively and reduce the strain on your heating and cooling system. You can learn more about insulation services and air sealing.
Why should I have weatherization work done when I can just get new windows?
New windows can help in some situations, but they usually do not address the biggest sources of energy loss in a home. In many homes, the attic, crawl space, and other hidden leakage points are responsible for far more air loss than the windows. Weatherization focuses on sealing and insulating the areas that have the greatest impact on comfort and efficiency. If your home still feels drafty or uneven after basic upgrades, weatherization services may offer a better long-term solution.
How much will a weatherization project cost me?
The cost of a weatherization project depends on the size of the home, the areas being treated, and the amount of work needed to improve performance. Some homes may only need targeted air sealing, while others benefit from a broader combination of insulation and efficiency upgrades. The best way to understand scope and cost is to start with a professional evaluation. You can schedule service or review our financing options.
Insulation and Air Sealing FAQs
Why do I need air sealing in my attic/crawlspace?
Air sealing helps close the gaps and openings that allow air to move in and out of your home. In the summer, this can mean cooled air escaping into the attic or outdoor air entering the living space through the crawl space. In the winter, it can mean warm air escaping and cold air entering. Proper air sealing improves comfort, supports better HVAC performance, and makes insulation work more effectively. Learn more about air sealing services.
How to air seal attic?
Attic air sealing involves identifying and sealing the hidden gaps, penetrations, and openings where indoor air escapes into the attic. Common leakage points include top plates, wiring penetrations, pipe openings, duct chases, and recessed fixtures. Because these areas can be difficult to find and treat correctly, attic air sealing is often most effective when done as part of a professional assessment. Learn more about attic air sealing and related attic insulation services.
What type of insulation is the best?
The best insulation depends on the area of the home, how much space is available, the existing conditions, and the performance goals for the project. Some situations call for blown-in insulation, while others may benefit from spray foam, cellulose, or other materials. The right choice depends on how the insulation will work with air sealing, moisture control, and the rest of the home. You can review our different insulation options to learn more.
Home Testing and Diagnostic FAQs
What is a blower door test and what does it measure?
A blower door test is a diagnostic tool used to measure how much air is leaking through your home. During the test, the home is depressurized so hidden leaks and problem areas can be identified more clearly. This helps show where conditioned air is escaping and where outside air may be entering. It is one of the most useful ways to diagnose comfort and efficiency issues before deciding on improvements. Learn more about our blower door testing and home energy audits.
Moisture and Mold FAQs
How do you get rid of mold?
Mold problems usually start with moisture problems. While surface treatment may help temporarily, long-term improvement depends on identifying where moisture is coming from and correcting the underlying conditions that allow mold to grow. That may include humidity control, crawl space improvements, air sealing, or insulation updates depending on the home. If mold is recurring, it is important to address the source rather than just the symptom.
How to treat mold?
There are products that can clean or neutralize mold on affected surfaces, but lasting results depend on preventing moisture from returning. Mold tends to grow where humidity, condensation, and organic material are present, especially in crawl spaces, basements, and other poorly controlled areas. Treating the growth is only one step. The larger goal is controlling the environment that allowed it to happen.
