Especially Important for Coastal & Harsh Marine Environments

Introduction

Dear Valued Customer, Thank you for choosing Glassmen Hermanus for your high-quality aluminum windows and doors. Our products are engineered for durability, using premium materials with protective finishes (such as powder coating or anodizing) that perform exceptionally well — even in demanding conditions. However, South Africa’s coastal regions expose homes and buildings to salt-laden air, high humidity, strong winds, and salt spray — factors that accelerate the buildup of corrosive deposits if not addressed regularly. With proper care, your investment can last for many years while maintaining its appearance and smooth operation. Neglecting maintenance in these harsh environments can lead to premature wear, corrosion, or component failure, potentially requiring expensive part replacements

Why Regular Maintenance Matters in Coastal Areas

Salt deposits from sea air settle on frames, hardware, and seals. Over time, these can:
  • Cause pitting or chalking on finishes

  • Affect moving parts (hinges, rollers, locks)

  • Degrade seals and weather-stripping

  • Reduce overall performance and longevity

Proactive care removes these deposits and prevents issues before they become major problems.

Recommended Maintenance Schedule

  • Coastal / Marine / Harsh Environments (within ~5–10 km of the sea, including Cape Town coastal areas): Clean and inspect every 1–3 months (monthly is ideal during windy/summer seasons).

  • Inland / Less Exposed Areas: Clean and inspect every 6–12 months.

Tip: Increase frequency if your property faces prevailing winds from the ocean, isunsheltered, or experiences heavy pollution.

Step-by-Step Cleaning Instructions

  • Rinse First Use a hose or bucket of fresh, clean water to thoroughly rinse all exterior surfaces (frames, sills, tracks, and glass). This removes loose salt, dust, sand, and debris — the most critical step in coastal areas!

  • Gentle Cleaning Prepare a mild solution of warm water and a pH-neutral dishwashing liquid (avoid harsh chemicals, acids, alkalis, or abrasive cleaners). Use a soft cloth, sponge, or non-abrasive brush to gently wipe frames, sills, and hardware. Clean glass at the same time

  • Rinse Thoroughly Rinse all surfaces completely with fresh water to remove any soap residue or remaining salt. Pay special attention to corners, tracks, drainage holes, and crevices where salt can accumulate.

  • Dry and Inspect Wipe dry with a clean, soft cloth (optional, but helps prevent water spots). While drying, inspect for:

  • Buildup or staining
  • Damaged/worn seals or weatherstripping
  • Stiff or noisy hardware
Important Do’s and Don’ts Do — Use only mild, non-abrasive cleaners and soft tools Do — Rinse generously with fresh water (this is non-negotiable near the sea!) Don’t — Use abrasive pads, scouring powders, strong solvents, acids, bleach, or high-pressure washers close to seals/hardware Don’t — Allow salt, dirt, or debris to build up in tracks or joints

Hardware & Moving Parts Care

  • Lubricate hinges, rollers, locks, handles, and tracks every 3–6 months (more often in coastal areas) using a silicone-based spray (avoid oil-based products that attract dust).

  • Keep tracks and drainage channels free of dirt/leaves for proper water runoff

  • Operate windows and doors gently to avoid stressing components.

Additional Tips for Longevity

  • Inspect seals and gaskets annually — replace if cracked or hardened.

  • Avoid contact with construction chemicals (cement, plaster, etc.) during renovations.

  • For stubborn spots (rare with regular care), use isopropyl alcohol sparingly and rinse immediately.

Warranty Details

Glassmen Hermanus provides a limited warranty against manufacturing defects in materials and workmanship, subject to proper installation and maintenance.

Coverage Periods (may vary by product/system; enhanced options available for coastal use):

  • Structural integrity of Aluminum frames/profiles: 10 years

  • Powder-coated/anodized finishes: 10 years (adhesion, chalking, fading; often reduced to 5 years in coastal/marine environments)

  • Hardware (hinges, locks, rollers, etc.): 3 years

  • Seals/gaskets/weatherstripping: 3 years

  • Installation workmanship (by us): 3-5 years

Retain proof of purchase and maintenance records. Report suspected issues promptly with photos for assessment.

Key Conditions for Validity (Critical in Coastal Areas):

  • Warranty requires adherence to these maintenance guidelines, with regular documented cleaning, rinsing, and lubrication (especially every 1–3 months near the sea).

  • Coverage excludes normal wear, environmental corrosion (e.g., salt damage if maintenance neglected), misuse, unauthorized repairs/modifications, impact damage, or exposure to harsh chemicals.

  • In severe marine zones, enhanced finishes (e.g., marine-grade powder coating or anodizing) and professional inspections may be required for full coverage.

Professional Service Reminder

While DIY cleaning keeps your windows and doors looking great, we strongly recommend booking a professional service inspection with [Your Company Name] at least once a year (or every 6 months in very harsh coastal conditions). Our trained technicians can:

  • Deep-clean hard-to-reach areas

  • Lubricate and adjust hardware

  • Check for early signs of wear or corrosion

  • Replace seals or parts before small issues become costly repairs

Early intervention prevents the need for major replacements, helps preserve your warranty, and ensures long-term performance in our challenging climate.

In Summary:

“Protecting your investment in our harsh coastal climate — one maintenance visit at a time.” We appreciate your trust in our products and look forward to supporting you longterm!
