While installing Aluminium Doors and Windows, 7 Things You Should Keep in Mind.
Aluminium doors and windows have grown in popularity due to their sleek aesthetics, durability, and energy efficiency. However, achieving the full benefits requires careful planning and skilled installation. This guide walks you through key considerations—from design and site preparation to sealing, maintenance, and long-term performance.

Aluminium doors and windows have grown in popularity due to their sleek aesthetics, durability, and energy efficiency. However, achieving the full benefits requires careful planning and skilled installation. This guide walks you through key considerations—from design and site preparation to sealing, maintenance, and long-term performance.
1. Accurate Measurement & Opening Preparation
Why It Matters:
Precise measurements ensure proper fit and thermal efficiency. An error as small as 10–20 mm can lead to expensive misfits or operational issues.
What to Do:
- Measure height, width, and depth of the openings—not just trimming sizes.
- Account for thermal expansion gaps, custom glazing depth, and frame tolerance.
- Verify walls are straight, level, and square. Any irregularity can warp operation or stress frames
- Use a sill pan and water-resistant membrane to direct water away from the structure
2. Select the Right Door & Window Type to Suit Use
Why It Matters:
Style, purpose, ventilation, security, and climate all influence the best option for your project
Popular Options:
- Casement windows – hinged and ideal for ventilation.
- Sliding windows or doors – space-saving, ideal for patios.
- Tilt-and-turn windows – offer flexible ventilation options.
- Flush‑sash or slimline frames – maximize views and natural light
Factors to Consider:
- Ventilation and daylight needs.
- Security – choose multi-point locks, laminated or toughened glass, and tested systems
- Thermal performance – prefer frames with thermal breaks, double/triple glazing, Low-E coatings
3. Professional Installation & Quality Assurance
Why It Matters:
Skilled installers improve fit, sealing, and long-term performance. Errors by amateurs often cause leaks, gaps, or alignment issues.
What to Ask / Verify:
- Does the supplier conduct multiple site surveys prior to installation?
(Some reputable companies visit the site three times to ensure precision) - Are they a one-stop builder–manufacturer–installer, or do they subcontract? Minimizing intermediaries reduces mistakes.
- Do they offer warranty coverage on frames, glazing, and installation? Reputable suppliers should provide solid after-care support .
Installer Tips:
- Ensure proper spacing of fixings.
- Use non‑reactive fasteners to avoid galvanic reactions.
- Confirm alignment, smooth operation, and secure locking before handing over.
4. Sealing, Insulation & Waterproofing
Why It Matters:
Poor seals result in drafts, water leaks, mold, and inefficient thermal performance.
Best Practices:
- Apply high-grade sealants — silicone or polyurethane — between frame and wall; avoid cheap bathroom sealants that wash out easily
- Use weatherstripping: V-strips, foam tape, door sweeps to seal sashes and moving parts
- Include thermal breaks and expanding foam insulation within frame gaps to improve energy retention
- Install a drip cap or capping to ensure better drainage and prevent water wicking into structure
Reddit Reality Check:
Homeowners reported rainwater infiltrating through failed silicone joints into interiors — emphasizing proper sealant selection and application. Gaps visible between frame and wall are unacceptable and must be resealed with polyurethane, not just silicone.
5. Handling Frames & Glass: Avoid Damage
Why It Matters:
Scratches or misaligned glass affect both aesthetics and function.
Tips:
- Transport and handle frames with care. Avoid metal tools or abrasive contact with coated surfaces
- Use protective gloves and padding during installation to prevent dents or scratches.
- Clean glass and frames after installation to remove debris that may scratch surfaces.
- Test during installation to ensure proper fit—misalignments can stress frames over time and impair sealing.
6. Post-Installation Checks & Commissioning
Once installed, it’s crucial to verify everything:
Checks to perform:
- Confirm doors/windows are level, square, and glide freely—no sticking or rattles
- Operate locks and multi-point latches to ensure full engagement.
- Inspect weather seals and look for any air or moisture penetration.
- Clean frames and glass, and verify drainage channels or weep holes are unobstructed
Ongoing Maintenance (at least annually):
- Clean with mild soap and water, avoiding harsh chemicals or abrasive pads
- Lubricate hinges, locks, and runners with silicone-based lubricant.
- Examine seals for wear; replace weatherstripping if needed.
- In coastal regions rinse frames frequently to remove salt deposits—look for premium 20‑year powder coatings or anodized finishes designed for marine exposure
7. Material & Finish Choices, Especially Near Coast
Why It Matters:
Coastal humidity and salt spray can degrade finishes and cause corrosion over time.
Recommendations:
- Opt for 25 μm anodized aluminium or premium 20‑year total warranty powder coat for superior external resistance .
- Avoid painting over factory coatings—it can destroy corrosion resistance and void warranties
- Inspect the finish periodically and wash off salt and pollutants at least quarterly in marine environments.
- Choose correct hardware: use stainless steel fasteners or components rated for salt air to reduce corrosion or galvanic breakdown.
