​Winterizing Your Home: Preparing for Winter
Introduction
Winterization is the process of getting your home ready for the challenges of winter, typically done in the fall before winter's chill sets in. This essential practice helps safeguard your home against problems such as burst pipes and heat loss due to gaps in the building structure. Home inspectors should grasp the importance of winterization and guide their clients through the process.
Preparing Your Plumbing
The havoc caused by burst pipes during cold weather can be disastrous, and it's essential to prevent it:

1. Insulate exposed water pipes in cold-prone areas, like attics, garages, and crawlspaces, using foam or fiberglass insulation.
2. Consider using plastic pipes as they can withstand cold expansion better than copper or steel.
3. Shut off the water supply for exterior pipes from inside the house and drain them.
4. Pay special attention to sprinkler systems, which can crack due to cold-weather expansion. Turning them off and using compressed air to remove any remaining water can help.

Maintaining Indoor Temperatures
Many plumbing components run through colder areas of the house, and it's crucial to maintain warm indoor temperatures to prevent freezing in unheated spaces.
Sealing Building Envelope Leaks
Leaky window and door frames and electrical outlets can lead to heat loss and cold air entry. Address these issues:

1. Detect drafts by feeling for air with your hand or using an incense stick to reveal smoke movement.
2. Repair leaks with tape or caulk.
3. On a breezy day, locate hidden leaks, often found at seams between building materials.

Adding Adequate Insulation
The attic is a prime area for heat loss, so ensure proper insulation. In colder climates, aim for at least 12 inches of attic insulation.
Utilize Storm Doors and Windows
Install storm doors and windows for enhanced insulation and protection from harsh weather conditions.
Maintaining Heating Systems
Your heating system works hard during winter, so ensure it's in good working order:

1. Test the furnace by adjusting the thermostat. If it doesn't respond quickly, consider repairs.
2. Replace a dirty air filter.
3. Ensure your furnace's oil or propane tank is full.

Handling Cooling Systems
Prepare cooling systems for winter:

1. Remove leaves and debris from outdoor condensing units.
2. Store window air conditioners when not in use to prevent damage and drafts.
3. Reverse ceiling fans to recirculate warm air trapped beneath the ceiling.

Chimneys and Fireplaces
Inspect your chimney and fireplace:

1. Check for nesting animals seeking shelter from the cold.
2. Ensure the damper opens and closes smoothly.
3. Clean the chimney if it hasn't been done in years.
4. Keep the damper closed when the fireplace isn't in use to prevent heat loss.

Protecting Your Roof
Prevent ice dams and water damage:

1. Clear debris from gutters to prevent ice dams.
2. Replace missing shingles.
3. Ensure proper drainage.

Landscaping
Prepare your outdoor space for winter:

1. Cover patio furniture.
2. Add a coat of sealer to your deck if needed.

Conclusion
In summary, winterization is a crucial set of measures to protect your home from damage caused by cold temperatures. These actions should be taken in the fall to ensure a comfortable and safe living environment throughout the winter. Pay attention to your plumbing, insulation, heating and cooling systems, chimney maintenance, and roof care to keep your home in top shape during the cold season

​When inspecting for mold, taking air samples is a must. Mold spores are tiny and can't be seen with the naked eye. Air samples, sent to a lab for testing, help identify the types of mold in your home, gauge the extent of the problem, and assess health risks. After mold removal, new samples confirm a clean environment.
Understanding Air Sampling
Air samples collect invisible mold spores. An air pump pushes air through a device, capturing these spores. InterNACHI inspectors often use this method.
Types of Devices
Three common devices:

1. Impaction samplers: Use a pump to stick spores on a slide.
2. Cassette samplers: Collect spores on a media, with some being disposable.
3. Airborne-particle collectors: Trap spores on a dish, helping identify mold species.

When to Sample and When Not to
Sample if you see mold, signs of growth (like dampness), or detect musty odors. Even when there's no visible mold, a few indoor samples can be taken as a precaution. Outdoor samples provide a baseline for comparison. Don't sample if someone's under a doctor's care for mold exposure, if there's a lawsuit regarding mold, or if it's not safe to take samples.
Where to Sample and Ideal Conditions
Sample where mold is suspected. In rooms with signs of moisture or musty smells, place the collection device about 3 to 6 feet off the ground. Sampling usually takes around ten minutes, but it can be quicker if there's lots of indoor activity or dust, like from construction. Ensure the area is closed during sampling, with windows and doors shut, and avoid using air exchangers or fans.
Weather Conditions
Extreme weather, like thunderstorms or high winds, can affect the sampling process. Rapid changes in air pressure can skew results by bringing in more spores. So, keep an eye on the weather when taking samples.
Practical Considerations
Air sampling is just one piece of the mold inspection puzzle. It can't confirm or dismiss a mold problem on its own. It's vital to combine it with visual inspections and other methods, like surface sampling, for a complete picture. Keep in mind that air sample results can be affected by various factors, so be cautious.
In Conclusion
In a nutshell, air sampling is a crucial tool for comparing particle levels in different areas and for assessing air quality before and after mold cleanup. It helps homeowners create a safe and healthy living space.
