Cold snaps around Lake Michigan can show up fast, and small issues can quickly turn into costly repairs. If you own a home in Lake Forest, a focused fall checklist helps you avoid ice dams, frozen pipes, and winter headaches. In this guide, you’ll find practical steps, local timing, and city rules so you can protect your investment with confidence. Let’s dive in.
When to start in Lake Forest
Plan exterior and mechanical prep before the first hard freeze. For the Lake Forest area, the first fall frost typically arrives in early to mid October, so aim to finish major outdoor tasks by late October. Check the projected frost date for zip 60045 to time your work using the Almanac’s local data. See typical frost timing for 60045.
Roof, gutters, and attic
Ice dams are a common cause of winter leaks. They form when warm attic air melts roof snow that refreezes at the eaves. The National Weather Service stresses clear drainage and good attic performance to prevent them. Review NWS guidance on ice dams.
- Clean gutters and downspouts so melting snow can drain away from your home.
- Inspect attic insulation and air sealing. For our region, ENERGY STAR recommends about R-49 on the attic floor when retrofitting. Check recommended R-values.
- Make sure soffit vents are open and not blocked by insulation. Add baffles if needed.
- If ice dams recur, avoid chipping at the ice. Focus on long-term fixes like air sealing and insulation, and call a pro when needed.
Protect plumbing and water lines
Frozen pipes are one of the most expensive winter problems. A few small steps can prevent most bursts. Get frozen pipe prevention tips.
- Insulate exposed pipes in basements, garages, crawlspaces, and exterior walls.
- Remove garden hoses, shut off and drain exterior spigots, and add faucet covers.
- Know where your main water shutoff is and test it.
- In extreme cold, keep interior doors open for airflow, maintain heat, and let faucets drip in vulnerable runs.
Heat, air, and fireplace safety
A safe, efficient heating system is essential in an Illinois winter.
- Schedule an annual furnace or boiler tune-up and replace filters before heavy use.
- If you use a fireplace or wood stove, book a professional inspection. Industry standards recommend at least an annual inspection and cleaning as needed. See CSIA’s inspection guidance.
- Test and place carbon monoxide alarms on each level and outside sleeping areas per safety guidance. Review CO alarm placement best practices.
- Consider a smart thermostat to manage comfort and savings. ComEd offers rebates for qualifying devices. Explore ComEd rebates.
Sump pumps and backup readiness
Rapid thaws and heavy precipitation can stress basements.
- Test your sump pump and clear the discharge path so it does not ice over.
- Consider a battery backup or secondary pump.
- Build a simple emergency kit and sign up for local alerts so you know about approaching storms and extreme cold. Register with Lake County Emergency Management.
Yard, irrigation, and exterior items
- Prune dead or diseased tree limbs to reduce breakage risk from snow or ice.
- Winterize irrigation lines and backflow preventers. Many homeowners schedule a professional blowout.
- Inspect exterior caulking and flashing, and secure loose railings or furniture before strong winds.
Driveways, sidewalks, and city rules
During snow events, Lake Forest restricts on-street parking so plows can work. The City enforces no on-street parking once snowfall exceeds two inches, and property owners should avoid placing shoveled or plowed snow back into the street or right-of-way. Review the City of Lake Forest snow and parking ordinance.
Keep sidewalks, hydrants, and nearby catch basins clear when possible. This helps prevent flooding during thaws and improves access for first responders.
Permits and hiring pros
Many mechanical replacements and alterations require permits in Lake Forest. Before installing a new furnace, whole-home generator, or significant HVAC upgrade, confirm requirements with the City’s Community Development team. See permit requirements in the municipal code.
When you hire, choose licensed and certified specialists. Keep receipts and inspection reports for your records, warranties, and insurance documentation.
Quick checklist and timeline
Use this simple list to stay on track.
Early fall
- Schedule furnace or boiler service and change filters.
- Book a chimney inspection if you plan to use the fireplace.
- Clean gutters and downspouts. Verify downspout extensions.
- Check attic insulation and seal noticeable air leaks.
- Winterize irrigation and remove hoses.
- Trim dead branches and secure outdoor items.
Late fall
- Insulate exposed pipes and cover outdoor faucets. Test your main water shutoff.
- Test the sump pump and consider a battery backup.
- Install or test smoke and CO alarms.
- If buying a smart thermostat, verify rebate eligibility before purchase.
Winter
- Safely clear roof edges with a roof rake if heavy snow piles up on eaves.
- Follow city parking and snow placement rules, and keep sidewalks and hydrants clear.
- If a pipe freezes, shut off water at the main and call a licensed plumber. Photograph and document any damage.
