Windows and doors are more than just openings in your home—they’re your first line of defense against the elements, a key part of your home’s curb appeal, and essential for comfort and security. So when something suddenly goes wrong, it’s not just annoying—it can be downright stressful.
At AM Group Exteriors, we’ve helped countless homeowners in London with windows and doors, troubleshooting everything from sticky locks to foggy glass. Whether your front door won’t close or your windows are leaking cold air, here’s a guide to the most common problems and how to deal with them—plus when it’s time to call in the pros.
Common Door and Window Problems—and How to Fix Them
1. The Door Won’t Close or Lock Properly
This is one of the most common issues we see with exterior doors. If your front or back door won’t close all the way or the lock won’t engage, it could be due to several reasons.
Check for Obstructions
Before jumping to conclusions, check under and around the door. Something as simple as a doormat corner or a small rock caught in the frame can prevent proper closure.
Weather and Warping
Here in London, ON, we experience significant temperature swings throughout the year, and that can take a toll on your doors. Materials like wood and PVC can expand in the summer heat or contract during the winter, causing misalignment. Try wiping the door edges with a damp cloth and letting them dry. This simple trick can sometimes solve minor swelling.
Lock Alignment Issues
If the door closes but doesn’t lock, inspect the latch and strike plate. If they’re misaligned, a slight adjustment may correct the issue. You can unscrew and reposition the plate so it lines up properly, but if it’s still sticking or loose, don’t force it. A professional technician can realign or replace the mechanism without damaging the door.
2. Key Won’t Turn in the Lock
Nothing’s more frustrating than fumbling with a key that won’t budge—especially when you’re running late or trying to get in out of the rain.
Try this quick fix: rub a regular graphite pencil along the key’s teeth. Then, insert and remove the key a few times. The graphite acts as a dry lubricant, helping to clear any minor obstructions or friction in the lock. If it still resists, the internal components could be worn out or corroded. That’s a good time to have it looked at by a local windows and doors expert in London.
3. Cracks in the Door or Window Glass
Small cracks often go unnoticed—until they grow into something bigger. If you spot any fracture, whether in the frame or glazing, it’s important to address it quickly. A cracked door panel weakens your home’s security and insulation, and a damaged window can escalate into a costly full replacement if moisture gets in.
Don’t wait for the next storm to test your home’s resilience. AM Group Exteriors provides top-tier solutions for windows and doors in London, Ontario, including inspections and full replacements when necessary.
4. Loose or Broken Door Handles
Over time, handles can start to wiggle or stop turning properly. This usually means a screw has come loose behind the hardware.
You can remove the knob or handle using a screwdriver and tighten the interior screws. If the backing plate or internal latch appears worn or damaged, it may need to be replaced. Be gentle during the repair process—if you accidentally strip a screw or damage the internal mechanism, it could leave the door unusable until it’s fixed.
5. Door Slams into the Wall
If your door keeps banging into the wall every time you open it, you’re not alone. That repeated impact can damage both the wall and the door handle.
Installing a basic doorstop can do the trick. You can attach one to the baseboard or opt for a hinge-mounted style that’s discreet and effective. It’s a quick, inexpensive fix that saves you future patchwork.
6. Water Leaks Around the Door
With Ontario’s unpredictable weather, water leaks are a problem many homeowners face. Start by checking for clogged drainage channels at the bottom of the door frame. If they’re blocked, water can back up and seep indoors.
Also, inspect the rubber weather seals around the door. Over time, they can dry out or become dislodged. If the seal appears worn or cracked, replacing it can significantly enhance your door’s performance and keep your entryway dry and comfortable.
7. Cold Drafts Sneaking In
A drafty door is more than just an annoyance—it’s a hit to your energy bill and comfort.
If your door is shut correctly but you still feel a breeze, check for visible gaps around the edges. Installing weatherstripping or a door sweep is a simple DIY project that can make a big difference. That said, if the door itself is warped or no longer sits flush, consider a full replacement.

8. Condensation Inside Window Panels
Condensation between the panes of a glass door or window is often a sign that the seal has failed. This can allow moisture to enter the air gap between panes, reducing your window’s insulating properties and clouding the view.
Unfortunately, once a seal has failed, the best solution is usually to replace the glass unit. On the other hand, if the condensation is on the outside of the glass, that’s a sign of sound insulation—it means your home is holding heat effectively. You can clear this up with some ventilation or by simply wiping it away.

FAQs
The lifespan of your doors and windows depends mainly on the materials and how well they’re maintained. Wood windows, for example, offer timeless appeal and can last over 30 years if they are regularly maintained, including repainting and sealing to prevent rot. When it comes to doors, wood options can last anywhere from 20 to 30 years with proper care and maintenance. Steel doors, on the other hand, are incredibly tough and often last 30 years or more with minimal upkeep.
Yes, replacing 20-year-old windows is often well worth it. Older windows tend to lose their insulating power over time, which can lead to higher energy bills, drafts, and even moisture damage. Newer windows are significantly more energy-efficient, making your home more comfortable while also enhancing curb appeal and overall value.
The cost of replacing windows can vary quite a bit depending on factors like the style of the window, the type of frame material, and the brand you go with. Some styles and materials are more budget-friendly, while others are designed for higher performance and durability, which can raise the price. It’s a good idea to get quotes from a few trusted contractors to understand what fits your home and budget best.
On average, double-pane windows last between 20 and 25 years. However, their lifespan can vary depending on the quality of the window and the conditions to which they’re exposed. Lower-quality windows may start showing signs of failure as soon as 10 years, especially if they are exposed to harsh weather conditions. Investing in higher-quality windows and proper installation can help them last longer and perform better over time.
