The causes can be different, so it is important to know what is causing the problem. Only then will you be able to tackle it effectively.<\/p>\n\n\n\n<p><strong>The most common causes of moisture accumulation:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Ventilation problems or lack of ventilation.<\/strong> This is often caused by mistakes made in the design of the premises or during construction. Differences in outdoor and indoor temperatures encourage condensation.<\/li>\n\n\n\n<li><strong>Rising groundwater levels.<\/strong> Higher risk in spring and autumn. Basements are often flooded and the humidity level rises rapidly, and it is difficult to dry out a room like a basement.<\/li>\n\n\n\n<li><strong>Penetration of moisture through cracks in the soil.<\/strong> This is common in basements that have not been constructed in accordance with the requirements and where there is damage to the walls.<\/li>\n<\/ul>\n\n\n\n<p>To know exactly why your basement is accumulating excess moisture or mould, you can have a <a href=\"https:\/\/bepelesio.lt\/en\/mould-testing\/\">mould or moisture test.<\/a> This will help you to identify the exact cause and find the most effective solution to eliminate damp in your basement.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"kuo-pavojinga-dregme-ir-pelesis-rusyje\"><strong>What is the danger of damp and mould in basements?<\/strong><\/h2>\n\n\n\n<p>Basement dampness is not just a cosmetic problem &#8211; its consequences can be much more serious than they first appear. Uncontrolled condensation <strong>creates the perfect conditions for mould and fungi to grow<\/strong>, which are difficult and often expensive to eradicate. In addition, damp is damaging to belongings, health and the whole building.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"pelesio-zala-zmonems\"><strong>Damage to humans from mould<\/strong><\/h3>\n\n\n\n<p>Humidity in the room creates favourable conditions for the growth of micro-organisms that are <a href=\"https:\/\/bepelesio.lt\/en\/damage-to-the-body-from-mould\/\">harmful to humans<\/a>. <strong>Mould gives off toxic substances that are particularly dangerous for the respiratory tract.<\/strong> People with weaker immunity are more likely to suffer from diseases such as aspergillosis.<\/p>\n\n\n\n<p>Mould can cause toxic reactions in the body, promote inflammatory processes, sinusitis and other ailments. It is particularly dangerous for people with respiratory diseases, allergies or weakened immunity. Less well-known but important, mould can also adversely affect the skin, especially in people with eczema or other skin conditions.<\/p>\n\n\n\n<p>In addition, mould gives off an unpleasant odour which, if present in large numbers in the basement, can spread to the living areas, thus reducing the overall comfort of the home.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"2240\" height=\"1260\" src=\"https:\/\/bepelesio.lt\/wp-content\/uploads\/2025\/05\/destruction-of-a-hornets-nest-36.png\" alt=\"A man holding an inhaler \u2013 toxic substances released by mold can trigger a mold allergy\" class=\"wp-image-4489\" title=\"\" srcset=\"https:\/\/bepelesio.lt\/wp-content\/uploads\/2025\/05\/destruction-of-a-hornets-nest-36.png 2240w, https:\/\/bepelesio.lt\/wp-content\/uploads\/2025\/05\/destruction-of-a-hornets-nest-36-300x169.png 300w, https:\/\/bepelesio.lt\/wp-content\/uploads\/2025\/05\/destruction-of-a-hornets-nest-36-1024x576.png 1024w\" sizes=\"(max-width: 2240px) 100vw, 2240px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"pelesio-zala-pastatui\"><strong>Mould damage to the building<\/strong><\/h3>\n\n\n\n<p><strong>Over time, moisture damages the finishes, ceilings, floors and walls,<\/strong> which reduces the value of the property and can lead to costly repairs in the future.

Basement dampness is no exception &#8211; if you want to eliminate it, it is important to first understand why it is accumulating in your premises.<\/p>\n\n\n\n<p>Here are some of the most common situations and what they might mean:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>If water droplets accumulate on the walls and ceilings,<\/strong> the problem is likely to be insufficient ventilation.<\/li>\n\n\n\n<li><strong>If the droplets are only on the walls,<\/strong> inadequate or damaged waterproofing is most likely to be to blame.<\/li>\n\n\n\n<li><strong>If puddles are on the floor,<\/strong> the water table may have risen.<\/li>\n<\/ul>\n\n\n\n<p>Once the situation is identified, the most appropriate action can be taken to not only reduce excess moisture in the basement, but also to prevent the development of mould in the future.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"pagerinkite-ventiliacija\"><strong>Improve ventilation<\/strong><\/h3>\n\n\n\n<p>If there is no natural air circulation in the basement, moisture is trapped, condensation builds up and eventually mould develops. The simplest solution is to <strong>install vents or open existing vents if they are closed.<\/strong><\/p>\n\n\n\n<p>Ventilation grilles in the door or window can also help. If this does not help, it is worth considering a mini-fan or an electric ventilation system. In the case of external walls with pipes, these should be insulated to prevent moisture condensation.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"2240\" height=\"1260\" src=\"https:\/\/bepelesio.lt\/wp-content\/uploads\/2025\/05\/Add-a-heading-3.png\" alt=\"Wall vent \u2013 for natural basement ventilation\" class=\"wp-image-4491\" title=\"\" srcset=\"https:\/\/bepelesio.lt\/wp-content\/uploads\/2025\/05\/Add-a-heading-3.png 2240w, https:\/\/bepelesio.lt\/wp-content\/uploads\/2025\/05\/Add-a-heading-3-300x169.png 300w, https:\/\/bepelesio.lt\/wp-content\/uploads\/2025\/05\/Add-a-heading-3-1024x576.png 1024w\" sizes=\"(max-width: 2240px) 100vw, 2240px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"sumazinkite-gruntiniu-vandenu-poveiki\"><strong>Reduce exposure to groundwater<\/strong><\/h3>\n\n\n\n<p>If puddles accumulate on the basement floor, it is likely that the problem is related to rising groundwater levels.

If the problem is minor, you can <strong>use special waterproofing paints or putties to create a moisture barrier from the inside.<\/strong><\/p>\n\n\n\n<p>If the walls are cracked, seal them with waterproofing compounds.

In some cases, eliminating mould in the basement without the intervention of specialists can also help.<\/p>\n\n\n\n<p><strong><a href=\"https:\/\/bepelesio.lt\/en\/folk-remedies-against-mould\/\">You can first try folk remedies for mould:<\/a><\/strong> vinegar, baking soda, castile soap, tea tree essential oil, hydrogen peroxide. There are also various special remedies for mould.<\/p>\n\n\n\n<p>In addition to major repairs or specialist help, there are a few simple steps you can take to help <strong>reduce or at least slow down the build-up of damp:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Use dehumidifiers<\/strong> &#8211; both electric dehumidifiers and adsorption agents (special salts, granules or silica gel). They help regulate humidity and reduce condensation.<\/li>\n\n\n\n<li><strong>Ventilate your cellar as often as possible<\/strong>, especially on dry, sunny days &#8211; open the window, leave the door open to allow air to circulate.<\/li>\n\n\n\n<li><strong>Do not clutter the walls with objects<\/strong> &#8211; leave at least 5-10 cm of space between the walls to facilitate drying and prevent mould build-up.<\/li>\n\n\n\n<li><strong>Lift items off the floor<\/strong> &#8211; store boxes, supplies or tools on shelves, trays or special stands so they do not touch damp surfaces.<\/li>\n\n\n\n<li><strong>Use waterproofing paints or products<\/strong> on smaller areas of walls or floors &#8211; this helps to reduce the ingress of moisture from inside.<\/li>\n<\/ul>\n\n\n\n<p>These simple measures can help to manage the situation and delay the need for more serious work.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"pelesio-naikinimas-rusyje-kada-i-pagalba-pasitelkti-profesionalus\"><strong>Mold control in the basement: when to bring in the professionals?<\/strong><\/h2>\n\n\n\n<p>These measures can be effective if mould in the basement is detected early and the affected area is small. However, <strong>if the mould is extensive (e.g. more than 1 square metre), if it keeps recurring, or if you are afraid of damaging the finish when cleaning, then it is a good idea to seek professional advice.<\/strong><\/p>\n\n\n\n<p>It is important to realise that even successful mould removal will not have a lasting effect if the cause of the mould (usually excess moisture in the basement) is not addressed.
