Spring: fresh start after winter
Delaware winters can be hard on siding. In spring, inspect for hail damage, loose fasteners, and any gaps that may have opened during freezing temperatures. Clean the surface with a gentle detergent and soft brush to remove salt and grime carried by winter winds. Check caulking around windows and doors and refresh as needed to keep moisture out behind the siding.
A spring touch-up is a good time to review flashing at corners and edges. If you notice any staining near the base or along the bottom edge, that’s a signal to bring in a siding specialist for a moisture check.
Summer: sun and humidity management
Heat and humidity drive expansion and contraction in many siding materials. In Delaware, look for color fading and any buckling on sun-facing walls. Regular rinsing helps prevent mildew buildup in shaded or humid spots. If you see paint failure or panel edge separation, it’s time to have a pro evaluate the condition and method of restoration that fits the climate.
Ensure overhangs and gutters are clear so water doesn’t cascade onto siding from the roofline. Proper drainage reduces the chance of water intrusion behind the panels.
Fall: prep for winter
As temperatures drop, check caulk and seals around doors and windows again. Hairline cracks can widen with frost, so re-sealing helps maintain an airtight exterior. Consider scheduling a professional inspection to verify that flashing, joints, and seams are sealed before heavy grills of wind and rain roll in.
Winter: ongoing protection
In Delaware, subfreezing temperatures can cause siding materials to become brittle. If you’re inside during a thaw, take a moment to inspect exposed edges from interior light. If you notice moisture infiltration from the outside during heavy rain or snowmelt, contact a siding specialist promptly to prevent wall damage.
