How to Inspect Your Windows, Doors, Roof & Siding Before Cold Weather Hits
As winter approaches in Pennsylvania, it’s essential to ensure your home’s exterior is prepared to withstand freezing temperatures, snow, and ice. A little preparation now can help prevent drafts, water damage, and costly repairs later. Use this winter home maintenance checklist to inspect your windows, doors, and siding before the cold sets in. You may also want to review our guide for finding leaks in your home.
Window Inspection: Stop Drafts and Heat Loss
Your windows are one of the biggest sources of heat loss in a home. Here’s what to check before winter:
Check for Drafts: On a windy day, feel around the window frames for cold air. If you notice drafts, it may be time to replace the weatherstripping or reseal the edges.
Inspect Caulking and Sealant: Cracked or missing caulk can allow water and cold air to seep in. Fresh caulk around window frames improves insulation and prevents moisture damage.
Examine Glass and Frames: Look for cracks, loose panes, or condensation between glass layers — signs of a broken seal that can reduce energy efficiency.
Clean Weep Holes: Ensure small drainage holes at the bottom of window frames are clear of debris to prevent trapped water and ice buildup.
Check Exterior Paint or Finish: Peeling paint or bare wood leaves windows vulnerable to rot — touch up these areas before winter weather arrives.
Drafty doors can quickly drive up heating bills. A thorough door inspection helps you keep the warmth inside where it belongs:
Test for Gaps and Drafts: Close doors and check for light or air leaks. Replacing worn weatherstripping or a damaged door sweep can significantly improve comfort and energy efficiency.
Tighten Hinges and Hardware: Loose hinges can cause poor alignment and uneven seals. A quick tightening can help your door close properly.
Inspect Caulking Around Frames: Seal any cracks where the door frame meets siding or trim to prevent water intrusion and air leaks.
Check the Threshold: A cracked or warped threshold can allow cold air and moisture to enter. Replace or adjust it if necessary.
Refinish or Repaint if Needed: Wood doors, in particular, require a protective finish to resist swelling, cracking, and water damage during the winter.
Don’t forget to pay special attention to patio doors! We often find customers only focus on their entryway door when the patio door is actually the bigger issue.
Siding Inspection: Protect Against Moisture and Cold
Your siding is your home’s first line of defense against harsh winter weather. A quick siding inspection can reveal issues before they turn into expensive repairs:
Look for Cracks, Warping, or Loose Panels: Damaged siding can let water and pests in — fix or replace sections before freezing temperatures make repairs harder.
Check for Mold, Rot, or Stains: Moisture issues often start around gutters, windows, or rooflines. Addressing them early helps prevent bigger structural problems.
Inspect Paint and Sealant: A fresh coat of paint or sealant protects your siding from moisture and helps maintain your home’s curb appeal.
Clean the Surface: Remove dirt, mildew, and grime with a mild detergent or professional siding cleaning service.
Check Flashing and Trim: Make sure all joints, corner boards, and flashing are tight and properly sealed.
Your roof takes the brunt of winter weather. A proactive roof inspection can prevent leaks, ice dams, and costly damage:
Look for Missing or Damaged Shingles: Replace any cracked, curling, or missing shingles to stop water from seeping in.
Inspect Flashing: Check the metal flashing around chimneys, vents, and skylights for signs of rust or gaps, as these are common sources of winter leaks.
Clean Gutters and Downspouts: Clear out leaves and debris so melting snow can drain properly, reducing the risk of ice dams and roof leaks.
Check for Moss or Algae Growth: These can trap moisture and damage shingles over time — clean them off before temperatures drop.
Inspect Attic Ventilation and Insulation: Proper airflow and insulation help prevent ice dams by maintaining a consistent temperature on your roof.
Even the best DIY inspection can miss hidden issues. A professional exterior contractor can thoroughly evaluate your windows, doors, roofing and siding, spotting potential leaks, gaps, or damage before winter weather makes repairs more difficult. Scheduling a pre-winter inspection ensures your home remains energy-efficient, comfortable, and protected throughout the entire season.
