\nWinter is a true test of window quality. When the temperature drops and the difference between indoor and outdoor air grows, any flaws in installation or window maintenance become especially noticeable. Heat escapes, condensation appears on the panes, and in extreme cases even drafts occur. To prevent this, it\u2019s worth preparing your windows for the winter season\u2014not only for comfort, but also to save on heating costs.<\/span><\/p>\n

Fintecnic<\/span>, a manufacturer of modern PVC and aluminium windows, explains how to properly secure your joinery for winter, what mistakes to avoid, and when it\u2019s worth calling in the professionals for an inspection.<\/span><\/p>\n

Why is window maintenance before winter so important?<\/h2>\n

Although windows<\/a> are designed as durable, weather-resistant elements, regular maintenance has a huge impact on their lifespan. Frost, wind, and moisture are the joinery\u2019s worst enemies\u2014over time, they can cause microcracks in seals, weaken hardware, and reduce tightness.<\/span>
\nWell-maintained windows guarantee that <\/span>the heat stays inside<\/b>, and cold air doesn\u2019t seep in. This isn\u2019t just about comfort\u2014leaks can increase your heating bills by several percent during the season. Regular cleaning, maintenance, and adjustment of moving parts ensure that your windows glide easily and quietly, while their insulation parameters remain high for years.<\/span><\/p>\n

It\u2019s also worth remembering that <\/span>maintaining your windows is a requirement for keeping the manufacturer\u2019s warranty<\/b>. Fintecnic recommends having your joinery inspected once a year\u2014ideally in autumn. It\u2019s a simple way to avoid bigger issues in the middle of winter.<\/span><\/p>\n

Step by step\u2014how to prepare your windows for winter<\/h2>\n

Preparing your windows for heating season is something you can do yourself. Just a few simple steps can significantly improve comfort and warmth in your home.<\/span> <\/p>\n

1. Thoroughly clean panes and frames<\/h3>\n

Start with a thorough window wash. Use a soft cloth or sponge and a gentle cleaner. Avoid products with solvents\u2014they may dull PVC or aluminium surfaces. Clean frames aren\u2019t just about looks\u2014dirt in grooves and seals can make sashes hard to close and reduce tightness.<\/span> <\/p>\n

2. Inspect and maintain seals<\/h3>\n

Seals are key for insulation. Over time, they may become stiff or brittle due to UV and frost. Check their condition, and if you notice cracks or loss of elasticity\u2014replace them. It\u2019s good practice to lubricate seals with technical petroleum jelly or silicone spray. This prevents freezing and keeps the rubber flexible even at -20\u00b0C.<\/span> <\/p>\n

3. Adjust the hardware and sash pressure<\/h3>\n

Modern windows\u2014like those from Fintecnic\u2014allow for <\/span>seasonal adjustment of hardware<\/b>\u2014the so-called summer and winter mode. In winter, the sash should press more firmly to the frame to minimize air flow. But don\u2019t overdo it\u2014too much pressure can warp the frame and make opening difficult. If you don\u2019t have experience, call a service technician.<\/span> <\/p>\n

4. Lubricate hinges and moving parts<\/h3>\n

Hinges, handles, and catches are used every day. In winter, grease thickens, so it\u2019s good to apply a new, thin layer of technical oil or silicone. Use only products intended for window hardware\u2014regular grease may attract dust and damage protective coatings.<\/span> <\/p>\n

5. Check condition of panes and frames<\/h3>\n

Check that there is no condensation between panes and no distortions on the frames. Minor leaks can be sealed with silicone caulk. If you see bigger issues\u2014like a cracked frame\u2014contact a technician. A proper inspection will help you avoid heat loss and repairs in the middle of winter.<\/span> <\/p>\n

Common mistakes when preparing windows for winter<\/h2>\n

Many homeowners make mistakes that can lower insulation efficiency or even permanently damage their joinery.<\/span>
\nThe most common problem is <\/span>using overly strong cleaners<\/b>, leading to discoloration of PVC or micro-scratches on aluminium. Seals are often neglected\u2014yet they\u2019re responsible for tightness. Another mistake is <\/span>excessive adjustment of hardware<\/b>\u2014too much pressure makes windows drafty when open or hard to close.<\/span><\/p>\n

It\u2019s also risky to <\/span>neglect hinge lubrication<\/b>\u2014in freezing temperatures, metal elements may seize up, causing hardware to break. Remember\u2014even small issues in winter can mean a cold interior and higher heating bills.<\/span><\/p>\n

Professional inspection and window service\u2014when is it worth it?<\/h2>\n

Not all maintenance jobs are DIY-friendly. If you have doubts about tightness, or feel unsure adjusting hardware, it\u2019s best to leave it to specialists.<\/span>
