Composite Door Maintenance Guide
Keeping your composite door looking and performing perfectly
🧽 Regular Cleaning
Clean your composite door monthly with warm soapy water and a soft cloth. The door's composite material is durable and stain-resistant. Avoid abrasive cleaners or scouring pads which can scratch the finish. Dry with a clean cloth after washing.
🔧 Lubricate Moving Parts
Apply silicone-based lubricant to hinges and locks twice yearly (Spring and Autumn). This ensures smooth operation and prevents wear. Never use WD40 or oil-based lubricants. A light machine oil is suitable for locks but avoid over-application.
🪟 Clean Glazing
Use glass cleaner for any glazed areas in your door. For the composite surface, gentle cleaning with soapy water is sufficient. Look for any signs of condensation or seal failure in glazed panels and report to us if found.
💧 Check Seals & Hinges
Inspect weather seals and hinges annually. Look for any gaps, cracks, or deterioration. Modern weather seals typically last 15-20 years before needing replacement. Report any concerns to DWLG for professional assessment.
🧪 Test Operation
Monthly, gently operate your door through its full range of motion. Ensure it opens and closes smoothly. Test the locks, handle, and hinges. Listen for any unusual sounds. Report any changes to operation immediately.
☀️ Protect from Extreme Weather
While composite doors are weather-resistant, protecting from extreme conditions extends lifespan. Consider a canopy for heavy exposure. In harsh coastal areas with salt spray, more frequent cleaning helps prevent corrosion of hardware.
✓ Pro Tip: Composite doors are extremely low-maintenance compared to timber doors. With simple regular cleaning and occasional lubrication, your door will look and perform beautifully for 35+ years. Most issues are easily prevented through basic maintenance.
Frequently Asked Questions
Common questions about composite doors
What makes composite doors different from uPVC doors?
Composite doors are engineered with multiple materials (wood, PVC, foam, resins) creating superior strength, security, and thermal efficiency compared to uPVC-only doors. They provide better security, insulation, and aesthetic realism. While more expensive, they offer significantly better long-term value and performance, especially for front doors.
How long do composite doors last?
Properly installed and maintained composite doors typically last 35-50+ years. The solid core construction and weather-resistant materials ensure durability. Many manufacturers offer 10-30 year warranties. The lifespan depends on climate exposure, use patterns, and maintenance. DWLG installations are designed to achieve the full expected lifespan.
Can composite doors be repaired?
Yes, composite doors can be repaired in most cases. Hinges can be adjusted, locks and handles replaced, weather seals renewed, and glazing units replaced if needed. Complete door replacement is rarely necessary unless the frame is severely damaged. Most repairs are straightforward and covered under warranty. DWLG provides repair services and can advise on cost-effective solutions.
Are composite doors secure?
Composite doors offer superior security compared to other materials. The solid core construction is extremely strong and resistant to impact. Multi-point locking systems on all composite doors provide excellent security. Test results show composite doors outperform alternative materials in break-in resistance. They are ideal for front doors in any location.
What colour and style options are available?
Composite doors come in an enormous range of colours and finishes including whites, creams, blacks, greys, blues, greens, reds, and realistic wood-effect finishes (oak, rosewood, mahogany, etc.). Hundreds of style designs are available from contemporary to traditional, cottage to Victorian. Glazing, hardware, and decorative options are also extensive. We'll help you find the perfect match for your property.
How much will a composite door improve my energy efficiency?
Modern composite doors with A-rated glazing can reduce heating bills by 5-15% for the door area (depending on how much of your heat loss is through the door). While less dramatic than full window replacement, a quality front door installation with proper sealing reduces draughts and thermal loss significantly. Energy savings compound over the door's 35-50+ year lifespan.
How long does installation take?
A typical composite door installation takes 4-6 hours including removal of the old door, installation of the new door, sealing, testing, and cleanup. Weather can impact installation (we cannot install in heavy rain). DWLG will provide a specific timeline after your survey. Most installations can be completed in a single day with minimal disruption to your home.
What warranty comes with my composite door?
All composite doors include manufacturer warranty (typically 10-30 years depending on brand). DWLG provides an additional workmanship warranty covering installation quality for 10 years. Warranties cover defects in materials and workmanship but not normal wear or customer misuse. Full warranty terms are provided with your installation. We also offer optional extended care packages.
