Summer House Maintenance: 10 Essential Pre-Season Tasks

How Did Your Summer House Survive the Winter?

Ayvalik and the Edremit Gulf are among Turkey's most desirable summer destinations, attracting thousands of families who own second homes in the region. Yet during the winter months, these summer houses often sit empty for long stretches and are exposed to humidity, cold, salty sea air, and strong winds. A house that is not actively lived in develops problems differently than one that is — plumbing traps dry out, seals harden, humidity penetrates where it would not in a ventilated home, and small issues grow into expensive repairs before anyone notices them.

Opening your summer house in spring without a proper check-up can lead to unpleasant surprises — from burst pipes to mold-covered walls, from dead refrigerators to pest infestations. This 10-step checklist helps you start the season safely and comfortably, and ensures that the small investment of a careful inspection protects the much larger investment represented by the house itself.

1. Ventilation and Humidity Control

The first job when you open the house is to throw open every door and window for at least 2 to 3 hours of thorough ventilation. Stagnant air that has been trapped for months carries humidity, odors, and in some cases mold spores. If you detect mold, clean the affected areas with a diluted bleach solution and, more importantly, identify the moisture source before it spreads further. A dehumidifier running for a day or two can make an enormous difference in homes that have developed high humidity over winter.

2. Roof and Exterior Inspection

Inspect the roof for broken or displaced tiles after winter storms. Check exterior walls for cracked or falling plaster, and make sure rain gutters and downpipes are free of leaves and debris. Clogged gutters are one of the leading causes of facade damage, because water overflows behind the cladding and works its way into the structure. A 30-minute gutter cleaning each spring can prevent tens of thousands of lira in damage over the life of the house.

3. Plumbing Check

Open the main water valve slowly and listen for leaks or bursts. Cracked pipes caused by winter frost are extremely common in unheated homes, and catching them early can save you from major water damage. Check under sinks, around the water heater, and near any exposed pipes for signs of moisture, staining, or mineral deposits. Also verify that hot and cold water both reach every fixture at normal pressure.

4. Electrical System Check

Before switching the main breaker on, visually inspect all exposed cabling for damage from rodents or moisture. Rodents love to chew on cable insulation during winter, and a single gnawed wire can cause a short circuit or even a fire. Test the residual current device (RCD) by pressing its test button to confirm it trips correctly. If the RCD does not trip, replace it immediately — it is your primary protection against electric shock.

5. Window and Door Seals

Rubber seals harden and shrink over time, causing insulation loss and air leaks. Replace damaged gaskets and lubricate sliding door and window tracks for smooth operation. Check that locks and handles still function properly; salt air can cause hardware to seize up after a single winter if it is not periodically maintained.

6. Bathroom and Kitchen Hygiene

Run plenty of water down every drain. The water in the P-traps may have evaporated during the dry winter months; refilling them prevents sewer gas odors from entering the house. Clean and disinfect all fixtures, and check faucet aerators for mineral deposits that may have accumulated from standing water.

7. Garden and Outdoor Spaces

Check fences for damage, repair any loose paving stones, and inspect the irrigation system for leaks or blocked emitters before the hot season begins. A malfunctioning irrigation system can waste enormous amounts of water and kill expensive plantings before you realize anything is wrong.

8. Pest and Insect Control

Examine entry points around pipes, vents, and door thresholds. In a coastal climate like Ayvalik, ants, scorpions, and rodents commonly seek shelter in vacant homes. If you find signs of infestation, arrange a professional pest control treatment before you move in — it is much more effective to treat early than to fight an established infestation all summer long.

9. Furniture and Textile Care

Sand and re-oil any wooden furniture affected by humidity. Wash or sun-dry fabrics, cushions, and curtains to remove musty odors and prevent mildew. Outdoor cushions and umbrellas that were stored indoors should be inspected for any staining that may have developed during winter storage.

10. Safety Systems

Replace smoke detector batteries, verify the expiration date on fire extinguishers, and test any alarm systems before the first overnight stay. If your house has a carbon monoxide detector, test that too — this is especially important in homes with gas water heaters or gas cooktops.

Before You Leave for the Winter

The spring checklist is much easier — and repairs are much less expensive — if the house was properly closed down the previous autumn. Before leaving your summer house for the winter, drain all pipes that are exposed to freezing, shut off the main water valve, unplug appliances that do not need to remain on, cover outdoor furniture, and leave internal doors open to promote air circulation. Pouring a small amount of mineral oil into floor drains and toilet bowls prevents the trap water from evaporating completely and keeps sewer gases out of the house.

Many Ayvalik summer home owners now install simple smart monitoring systems — temperature sensors, water leak detectors, and security cameras — that alert them by phone if something goes wrong during the closed season. A water leak detected in January while the homeowner is in Istanbul costs a fraction of a flood discovered in April upon arrival. These monitoring systems have become affordable in recent years and pay for themselves quickly for any absent owner.

Leaving a trusted local caretaker with a key and a phone number is another low-cost but highly effective strategy. A short monthly walk-through by someone who knows the house can catch early signs of problems — staining on a ceiling, a dripping pipe, an unfamiliar smell — long before they become emergencies.
