How Often Should You Clean Your Windows in Phnom Penh?

Living in Phnom Penh means dealing with a unique set of environmental factors that affect your windows. From monsoon rains to construction dust, here's how often you should schedule professional window cleaning.

The Phnom Penh Factor

Cambodia's capital has a tropical monsoon climate with two distinct seasons. The wet season (May through October) brings heavy downpours that leave mineral deposits and water spots on glass. The dry season (November through April) brings dust storms and increased pollution from construction activity across the city.

Both seasons are hard on your windows, but in different ways.

Residential Cleaning Schedule

For most homes in Phnom Penh, we recommend professional window cleaning every two to three months. If your property is located near a construction site or a busy road — common in fast-growing areas like Boeng Kak, Tuol Kouk, or Chbar Ampov — you may want to increase that to monthly cleaning.

Properties with floor-to-ceiling glass or large window walls, such as those in BKK1 and Tonle Bassac condominiums, benefit from more frequent cleaning because dirt is far more visible on expansive glass surfaces.

Commercial Cleaning Schedule

Storefronts and restaurants should have their windows cleaned at least every two weeks. Customer-facing glass is one of the first things people notice, and dirty windows can subconsciously signal neglect.

Offices above ground level can get away with monthly cleaning, though buildings in dusty areas near Veal Vong, Ou Ruessei, or along major boulevards may need bi-weekly service.

Signs Your Windows Need Cleaning Now

• Water spots or mineral buildup visible from inside
• Reduced natural light in rooms that used to be bright
• Visible dust or grime on the exterior panes
• Mold or mildew growth around the window frame
• A hazy or streaky appearance even on sunny days

The Cost of Waiting Too Long

Postponing window cleaning isn't just an aesthetic issue. Mineral deposits from Phnom Penh's hard water can etch permanently into glass if left untreated for months. This means what starts as a simple cleaning job can turn into an expensive glass restoration — or even replacement.

Mold growth around window seals can also compromise the seal integrity, leading to air and water leaks. Regular cleaning prevents these issues before they become costly repairs.
