When Should You Replace Your Sliding Glass Door?
In this article, we’ll go over the signs that signal your sliding door needs replacement. We’ll also look at smart features to consider when choosing a new door. Let’s dive in.
What are Sliding Glass Doors?
Sliding glass doors are large doors with panels that slide horizontally to open instead of swinging in or out. They are usually made of glass framed in vinyl, wood, fiberglass or metal.
Sliding glass doors became popular in the 1950s and 60s. They were used a lot in modernist homes to blur the line between indoor and outdoor spaces.
These doors let in natural light and provide easy access to patios, decks and backyards. Homeowners still love using them this way today.
When Should You Replace a Sliding Glass Door?
With regular care and maintenance, a quality sliding glass door can last 25-30 years. But over time parts wear out and sealing degrades. Here are some signs it may be time for a new door:
Difficult to Open and Close
Do you have to yank hard or lift up for the door to slide? This usually means the rollers and track are misaligned or worn down. New rollers can help, but it’s a clue the door is aging.
Fogging Between Panes
If the sealed glass unit fogs up inside, the air tight seal has failed. Once the seal is broken, moisture builds up between the panes. Replacing the whole unit is the only fix.
Major Air Leaks
Do you feel cold drafts around the edges of the door? This suggests the seals have weakened over time. Adjusting the threshold or replacing the seals can temporarily help. But frequent air leaks usually indicate an old door near the end of its lifespan.
Condensation Issues
Excess moisture condensing on the frame or puddling below means the seals have degraded. Again, the only permanent solution is replacing the entire unit.
Security Concerns
Old sliding glass doors often lack modern security features. Replacing an outdated or damaged door with a reinforced model can offer much better break-in resistance.
High Energy Bills
Poor seals and little insulation mean older doors leak energy. Swapping in energy efficient sliding doors with double or triple pane glass can help reduce electricity and heating costs.
appearance and functionality. Modern sliding doors open and glide more smoothly. They better resist weather damage. New security and energy efficiency upgrades also provide peace of mind.
What to Look for in a New Sliding Glass Door
When selecting a replacement door, here are some key features to look for:
Energy Efficient Glass
Look for double pane or triple pane glass with argon gas fill and low-emissivity coatings. This boosts insulation, allowing less heat transfer through the door.
Durable Frame
Fiberglass, vinyl, composite and aluminum frames resist warping and cracking better than wood over time. They also insulate much better.
Smooth Rollers
High quality rollers inside the top and bottom tracks allow effortless sliding. Nylon or steel rollers last longer than plastic.
Tight Seals
Compression seals, pile seals and bulb seals keep outdoor air from infiltrating around the door edges and frame.
Security Locks
Multi-point locks and steel reinforcement rods provide protection against forced entry. Keyed locks add convenience.
Moisture Resistance
Frames with thermal breaks and durable finishes avoid condensation issues that lead to rot over time.
ADA Compliant Threshold
A low or flush threshold allows smooth rolling over the track in the doorway, great for wheelchairs.
Warranty
Look for at least a 10 year warranty on the door frame and 20 years on the glass unit. This protects against defects.
Automatic Closer
A motorized closer makes the heavy door easy to operate. It pulls the door shut when partially open.
Smart Features
Options like built-in blinds or tinting, WiFi connectivity and voice control take sliding doors to the next level.
Is DIY Installation an Option?
In theory, it’s possible to DIY if you have construction experience. But specialist tools for alignment and handling oversized glass make hiring a pro almost mandatory.
Given the cost of new doors, it’s worth paying extra installation fees to ensure it’s solidly leveled, sealed and secured for longevity. Otherwise flawed DIY installation can void warranties.
Revolutionize Your Living Space
Hopefully you now understand the tell-tale signs that a sliding door has reached the end of its lifespan. Replacing worn components like rollers and seals can extend its usefulness a bit longer.
But once condensation, fogging, major air leaks or security become an issue, it’s usually time to upgrade. A new energy efficient sliding door can revolutionize your living space with abundant natural light, easy access to the outdoors and modern comforts.
Conclusion
So if your door is showing its age, start researching replacement options. With the right quality materials and expert installation, your new sliding door will provide enjoyment for decades to come.
