Even a partial blockage can cause water to spill over instead of flowing through the system.<\/p>\r\n<h2>Why gutters overflow<\/h2>\r\n<p>Gutters are designed to collect rainwater and direct it into downpipes.<\/p>\r\n<p>If water cannot move through the system quickly enough, it will overflow.<\/p>\r\n<h2>The most common causes<\/h2>\r\n<h3>Blocked gutters<\/h3>\r\n<p>Leaves, dirt, and debris can build up in gutters over time.<\/p>\r\n<p>This restricts water flow and causes water to back up and overflow during heavy rain.<\/p>\r\n<h3>Blocked or undersized downpipes<\/h3>\r\n<p>If downpipes are blocked or cannot handle the volume of water, gutters will fill faster than they can drain.<\/p>\r\n<p>This leads to overflow, especially during heavy rainfall.<\/p>\r\n<h3>Incorrect gutter fall<\/h3>\r\n<p>Gutters need a slight slope to allow water to flow toward the downpipes.<\/p>\r\n<p>If they are not angled correctly, water can pool and overflow.<\/p>\r\n<h3>Damaged or sagging gutters<\/h3>\r\n<p>Over time, gutters can sag or become misaligned.<\/p>\r\n<p>This can create low points where water collects instead of flowing away.<\/p>\r\n<h3>Heavy rainfall exceeding capacity<\/h3>\r\n<p>In some cases, very heavy rain can exceed the capacity of the gutter system.<\/p>\r\n<p>This is more likely if the system is already partially restricted.<\/p>\r\n<h2>Where the water goes<\/h2>\r\n<p>When gutters overflow, water can run down walls, pool around foundations, or enter the building.<\/p>\r\n<p>This can lead to damage over time if not addressed.<\/p>\r\n<h2>What you can check<\/h2>\r\n<p>You can look for a few simple signs:<\/p>\r\n<ul>\r\n<li>Visible debris in the gutters<\/li>\r\n<li>Water spilling over specific sections<\/li>\r\n<li>Sagging or uneven gutter lines<\/li>\r\n<\/ul>\r\n<p>These can help identify the likely cause.<\/p>","ptb_mjr_ask_mj":"<p><strong>If it's overflowing, the water's not getting away fast enough.<\/strong><\/p>\r\n<p>There is usually something slowing it down.<\/p>","ptb_mjr_service_text_2":"<h2>How MJ Robertson approaches gutter issues<\/h2>\r\n<p>MJ Robertson is a maintenance company specialising in plumbing across Christchurch, including spouting and gutter repairs.<\/p>\r\n<p>When gutters are overflowing, the focus is on identifying what is restricting flow or affecting capacity.<\/p>\r\n<p>This may involve:<\/p>\r\n<ul>\r\n<li>Clearing debris and blockages<\/li>\r\n<li>Checking downpipes and connections<\/li>\r\n<li>Assessing gutter alignment and condition<\/li>\r\n<\/ul>\r\n<p>The aim is to restore proper drainage and prevent overflow.<\/p>\r\n<h2>When to arrange help<\/h2>\r\n<p>It is worth arranging assistance if:<\/p>\r\n<ul>\r\n<li>Gutters overflow regularly during rain<\/li>\r\n<li>You notice sagging or damage<\/li>\r\n<li>Water is affecting the walls or foundations<\/li>\r\n<\/ul>\r\n<p>Early attention can help prevent further damage.<\/p>\r\n<h2>Final thought<\/h2>\r\n<p>Overflowing gutters in Christchurch are usually a sign that water cannot move through the system properly.<\/p>\r\n<p>Clearing blockages and ensuring correct flow helps keep the system working as intended.<\/p>"},"ptb_taxonomy":{"category":[{"term_id":9,"name":"Spouting & Gutter Repairs","slug":"spouting-gutter-repairs","term_group":0,"term_taxonomy_id":9,"taxonomy":"category","description":"Overflowing gutters & damaged spouting can lead to bigger problems.
