A Fall Maintenance Checklist for Your Renovated Home
Your home renovation was a big investment. The renovation process may be over, but your home still has to get through its first winter. New windows, fresh plumbing and any new heating equipment all face their first real test once the cold arrives. That’s why a short fall walkthrough of your home helps you catch small issues while they're still small. It also gives you a clear list to share with your home renovation contractors, so nothing is waiting until spring.
Keeping water away from the house
Our team worked in insurance restoration before focusing on custom homes and renovations, so water is the first thing we think about. Water that sits against a foundation or slips past a seal can quietly undo good work, especially after an exterior renovation.
Clear eavestroughs and downspouts
Remove leaves and debris, then check each downspout outlet for blockages. If you spot leaks or sagging sections, get them repaired before the first freeze.
Check where the water goes
Downspouts should carry water away from your foundation. Make sure it doesn't land on a neighbour's property, your driveway or the sidewalk, where it can freeze. If you use a rain barrel, take it out of service before freezing weather. Then reconnect a downspout extension so drainage still leads away from the house.
Look closely where new meets old
Check for gaps around windows, doors and the spots where pipes or wires pass through exterior walls. Then photograph every place where an addition, replacement window, new door or new exterior finish meets the original house. If you see gaps, staining or loose materials, share the photos with your home renovation contractors before you try any repairs yourself.
Protecting plumbing before the first freeze
Shut off outdoor taps
Disconnect your garden hoses. If your home has an indoor shut-off for the outdoor taps, close it and let the outdoor lines drain.
Insulate pipes near cold spaces
Insulate exposed plumbing near exterior walls and in crawlspaces, attics and garages. Seal any cold-air leaks nearby. A kitchen renovation, bathroom renovation or new laundry room may have put plumbing along an exterior wall or through a once-unheated space. If so, ask your plumber to check its freeze protection.
Know your main shut-off
Everyone in the house should know where the main water shut-off is and how to use it in an emergency. Add its location to your renovation records.
Getting heating and ventilation ready for winter
Book a fall inspection with a licensed, insured HVAC contractor, and ask them to check the controls and any condensate drainage. At home, clean or replace your filters as the manufacturer recommends and look over your heating schedule. Pull furniture away from vents. Run your kitchen and bathroom exhaust fans, since they help clear moisture and indoor pollutants.
Your renovation project may have added a heat pump, a new thermostat, or a heat recovery or energy recovery ventilator (HRV or ERV). Those ventilators bring in fresh outdoor air while holding on to heat. Go over the operating and maintenance instructions with your installer. Ask for the right winter settings, and change anything left over from the end of construction.
Watching for moisture in finished spaces
Energy-saving upgrades make a home more airtight. Health Canada warns homeowners that a tighter home can hold more indoor humidity when ventilation can't keep up. That's why moisture deserves a closer look in a better-sealed living space.
Measure your humidity
A simple hygrometer will tell you where you stand. Health Canada recommends keeping relative humidity between 30% and 50%. Watch for condensation on windows and other cold surfaces.
Check your bathrooms
Confirm your exhaust fans vent to the outdoors. Run them while you bathe and for at least 30 minutes afterward. Repair any damaged caulking or grout around the shower.
Inspect finished basements
After basement renovations, look for staining, dampness and musty smells. If you find any, fix the source of the moisture. Paint or new finishes will only hide it.
As you walk through, check window frames, basement corners, cabinet interiors and flooring edges. Keep a dated photo log of anything you want your contractor to see.
Reviewing cold-weather safety
Ontario requires working smoke alarms on every storey and outside all sleeping areas. Since January 1, 2026, existing houses with a fuel-burning appliance, fireplace or attached garage also need carbon monoxide (CO) alarms beside each sleeping area. They need them on every storey as well, including floors without bedrooms. Certain other fuel-fired heating setups fall under the rule too.
If your home renovation added a floor or a bedroom, check that your alarms match the new layout. Test your CO alarms monthly. Follow the manufacturer's instructions for batteries and for replacing alarms at the end of their life.
Closing the loop with your records and your contractor
Finish by gathering your warranties, product-care instructions, service records and contractor contacts in one place. Then send your home renovation contractors a short list of concerns with photos, and ask for a walkthrough where needed.
Leave roof access, gas equipment and electrical work to qualified professionals. Call a general contractor about hidden leaks or signs of structural movement. A checklist can't replace an on-site assessment, so have a professional look at anything it turns up.
