Pre-Winter Home Maintenance Checklist for Lebanese Homes

Why Pre-Winter Prep Matters in Lebanon

Lebanon’s winter is short but punishing on homes. Beirut receives most of its annual rainfall in just 3–4 months (December through March), with the heaviest rains concentrated in January and February. Mountain areas above 800m receive significant snow. The combination of rain volume, temperature swings, and coastal wind creates specific stresses on buildings.

The consequences of skipping pre-winter maintenance aren’t just inconvenience — a roof leak that goes undetected until February can cause thousands of dollars of water damage to walls, ceilings, floors, furniture, and electrical systems. A burst pipe in a Jounieh chalet can go unnoticed for weeks, causing structural damage. The cost of prevention is almost always a fraction of the cost of repair after the fact.

Plumbing and Water Systems

Water-related problems are the most common winter maintenance issue in Lebanese homes. Check:

Hot water system

Test your water heater now while summer habits might have it running below winter demands. Flush the tank (solar and electric heaters accumulate sediment) and check the pressure relief valve. A water heater that barely kept up in mild weather will struggle in cold. See our plumbing services.

Exposed pipe insulation

Any water pipes running through unheated spaces — roof terraces, stairwells, external walls in mountain properties — should be insulated with foam pipe lagging before temperatures drop. At mountain properties above 900m, this is not optional. A frozen pipe that bursts can empty a water tank into a property in hours.

Outdoor taps and irrigation

Drain and close isolation valves on outdoor taps before frost risk (late October for mountains, December for Beirut). Garden irrigation systems should be drained and blown out if you have one.

Check for slow drips

A slowly dripping connection that’s tolerable in summer becomes a problem in winter when thermal expansion and contraction from temperature swings stress joints further. Fix slow leaks before winter.

Waterproofing and Drainage

This is the most critical pre-winter check for Beirut apartments.

Roof terrace and balcony waterproofing

If your apartment is on the top floor, or you have a private roof terrace, inspect the waterproofing membrane before the rains. Look for: cracks or blistering in the waterproofing layer, deteriorated sealant around drains and penetrations, areas where water pools after even light rain. A crack in roof waterproofing will result in a leak inside the apartment below. Repairs done in October take a few hours; repairs done after a January storm take longer and cost more because water has already entered.

Balcony drainage

Check that floor drains are clear of debris and flowing freely. A blocked balcony drain in a heavy Beirut winter rain will flood in minutes, and if the waterproofing on the balcony floor has any weakness, that water will find it.

Window and door seals

Inspect the silicone sealant around window frames, particularly on northwest-facing facades that take the most rain exposure. Old or cracked sealant allows water to track into the wall construction, causing the damp wall problems that are so common in Beirut winter. Resealing is inexpensive and fast. See our walls & ceilings service for damp wall repair.

Gutters and downpipes

Clear accumulated debris (leaves, dust, construction material) from gutters and check that downpipes run clear. A blocked gutter during heavy rain overflows and routes water behind the building facade — the primary source of damp patches on exterior walls.

Electrical and Heating Systems

Winter in Beirut puts a much higher load on electrical systems as heating, water heating, and lighting demands increase. In the mountains, it’s simply cold.

Heating units

If you have split ACs used for heating in winter, service them now (before October) while technicians are available. AC units used in heating mode don’t always work efficiently in Beirut winters below 10°C — some require a supplemental heat source. If you use diesel or gas heaters, have them serviced before first use and ensure adequate ventilation in the room.

Electrical load

Winter adds electric heaters, electric blankets, and higher AC/heat pump usage to circuits that already carry full appliance loads. If your breaker for a room trips frequently in winter, it may be undersized for the additional heating load — a dedicated heater circuit is the right fix. See our electrical services.

Outdoor lighting

Check that outdoor light fixtures have weatherproof seals intact. Water ingress into an outdoor fixture causes corrosion and short circuits. Replace any cracked fixture covers before the rains.

Windows, Doors, and Insulation

Most older Beirut apartments are cold in winter because windows and doors are poorly sealed — not because the insulation in the walls is bad (concrete has reasonable thermal mass). The biggest heat losses are typically at:

• Window frame perimeters — where the frame meets the wall. Check for gaps and reseal with silicone or expanding foam.
• Door thresholds and bottom gaps — a gap under a front door or balcony door is significant. Door sweeps and threshold seals are cheap and very effective.
• Old single-pane window panes — these are essentially no insulation. Secondary glazing (adding an inner layer) or replacement with double-glazing are significant upgrades but are a larger investment.

A quick test: on a windy day, hold your hand near window frames and door gaps. You’ll feel the draft at any significant gap. Seal what you find.

Outdoor Spaces

Beirut’s balconies and terraces take a beating in winter. Before October ends:

• Move or cover outdoor furniture. Beirut winter rain plus wind plus UV cycling destroys cushions and degrades metal furniture faster than most people expect.
• Check railings. Winter storms stress railings significantly. Any railing that wobbles or has corroded fixings needs attention before storm season, not during it.
• Trim trees and large plants. Overhanging branches dropped by winter storms are the most common source of gutters blocked and roofs scratched in Lebanon.
• Store or tie down lightweight items. Beirut winter storms regularly send flower pots, chairs, and garden items off balconies. A heavy plastic pot falling from a third-floor balcony is a serious hazard.
• Check external electrical. Garden lights, outdoor outlets — all should have weatherproof covers confirmed closed before rain season.

Mountain Property Specifics

If you have a chalet or apartment in Beit Mery, Broummana, Aley, Faraya, Zahle, or any area above 700m elevation, your winter prep list is longer:

• Pipe freeze protection is not optional. Insulate all exposed pipes. If the property will be unoccupied in freezing weather, drain the water system completely or maintain minimum heating.
• Check the roof structure. Mountain roofs need to handle snow load. Any sagging, cracked rafters, or damaged roofing tiles need addressing before snow. A roof that leaks under rain will leak badly under snow melt.
• Fuel for heating. Diesel and gas suppliers in mountain areas get busy in November. Order heating fuel early, not when you first get cold.
• Generator maintenance. Mountain properties rely more heavily on generators during winter power cuts. Service the generator in October, including oil, filters, and battery check.
• Access preparation. If your property is on a steep road, check the traction of your vehicle and whether the road is likely to be passable after heavy snow without chains.
