Preparing your home for winter: autumn checklist (Croatia)

HR EN

Croatian house exterior in autumn daylight, gutters and roof visible, Zagreb feel

Gigron

October is your last calm window before long rain and the first frosts. If you sort outdoor jobs and heating now, you spend less time on emergency calls in winter.

This preparing your home for winter guide is a practical autumn checklist for Croatia: what you can do yourself, what to leave to a pro, and how to write a clear request. Service prices vary by city and property condition - compare at least two or three offers, not just the lowest number.

Outdoor jobs before winter

Do outdoor points while it is still dry. Once prolonged rain starts, ladders and roofs get riskier, and appointment slots fill fast.

Cleaning gutters

Cleaning gutters is one of the cheapest preventive jobs - and one of the easiest to postpone. Leaves, moss and grit block the channel; water then runs down the wall, soaks the facade and can enter the roof structure.

What to do:

If the house has several storeys or a steep roof, call a contractor with proper gear. You can prepare access (parking, yard key) and photos of the problem.

Drainage around the house

Gutters are only part of the story. Check that drains near the foundations are clear and that water does not stand against the wall after rain. If you see damp in a basement or ground floor, note the spot - that helps the tradesperson.

Facade and windows - quick walk-around

You do not need a full facade wash right away. Quickly check cracks, peeling paint, window seals and places where water gets in. For larger work see facades. Fix smaller issues before frost - render and sealant hold better above freezing.

Heating: radiators, stoves and boilers

When outdoor work is done, move to the system that will run all winter. Most breakdowns hit in the first cold week, when everyone calls the same technicians.

Bleeding radiators

Bleeding radiators helps when the top stays cold and the bottom is warm, or when you hear gurgling. Air in the system cuts efficiency and stresses the pump.

Short steps (if you have the key and know where the expansion vessel / pressure gauge is):

  1. Turn heating on and let the system warm up.
  2. Open the bleed valve at the top of the radiator.
  3. Close it when water runs without air.
  4. Check system pressure and top up water only as the manufacturer describes.

If you cannot find the valve or pressure drops every week, leave it to a pro. Leaks or wrong pressure cause damage quickly.

For the full step-by-step method, see radiator not heating: how to bleed a radiator. For a broader look at heating trades, see heating.

Pellet stove service

Pellet stove service before the season saves nerves. Ash, dust and blocked channels cut efficiency and can shut the stove down at night.

A typical autumn service covers cleaning the firebox and heat exchanger, checking fans and sensors, door seals, and a test fire with your pellets. Store pellets dry - damp ones dust and clog the system. Find a technician via stoves and state make and model.

Gas boiler service - facts, not folklore

Gas boiler service (servis plinskog bojlera) before winter makes sense: cleaning, burner check, pressure, condensate drain (on condensing units) and safety parts. A regular check lowers the chance of failure when you need heat most.

Is service "mandatory"? It depends on appliance type, installation and warranty - ask an authorised technician or the manufacturer what your booklet requires, not forums. Odd noises, error codes or frequent shut-offs: do not wait for snow.

For approximate 2026 prices for boiler and pellet stove servicing, see gas boiler service cost. For checks see regular gas boiler service and boilers.

Indoors: seals, thermostat and what to leave to a pro

Window and door seals

Draughts around windows and entrance doors raise consumption. Check:

You can fit simple self-adhesive seal yourself. Larger frame repairs or sash adjustment belong to a joinery / PVC specialist.

Thermostat and habits

Check that the room thermostat (or app) works and zones are set sensibly. Lowering temperature at night and while you are out saves energy, but extreme shut-offs in older houses can encourage damp - keep a reasonable minimum.

What to leave to a professional

Leave to a specialist:

You can usually: clear gutters on a low building, bleed radiators, replace simple seals, and prepare a list plus photos.

How to write a request for a tradesperson

A clear request saves time. Include property type and city, what you need (e.g. gutter clean; pellet stove service make X model Y), what you noticed, preferred date and access (parking, ladder).

Example: "House in Zagreb, ground floor + first floor. Need gutter cleaning and a quick joint check. Gutters partly blocked with leaves. Slot this or next week, morning."

Second: "Pellet stove service, make ..., model .... Last service last year. Stove sometimes shuts off after ignition. Slot before end of October."

Prices differ - compare several replies and ask what the price includes (materials, call-out, waste).
