A small leak that goes unnoticed for a few hours can quickly turn into warped floors, mold growth, or structural repairs. The good news is most problems give warning signs, and many are completely preventable.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This <\/span><a href=\"http:\/\/redfin.com\" data-wpel-link=\"external\" target=\"_blank\" rel=\"external noopener noreferrer\"><span style=\"font-weight: 400;\">Redfin<\/span><\/a><span style=\"font-weight: 400;\"> article shows how homeowners can stay ahead of water damage before it starts.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">1. Start with the basement and foundation<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">In older homes, the basement or crawlspace is often where trouble begins. According to Tim Tracy, Regional Manager at leading foundation repair company <\/span><a href=\"http:\/\/www.groundworks.com\/\" data-wpel-link=\"external\" target=\"_blank\" rel=\"external noopener noreferrer\"><span style=\"font-weight: 400;\">Groundworks<\/span><\/a><span style=\"font-weight: 400;\">, older homes were simply not built for modern water use. \u201cOlder homes with basements were never designed to resist long-term water intrusion, and today\u2019s usage means even small leaks can cause major disruption.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Over time, foundations naturally deteriorate. \u201cOver decades, concrete, block, stone, and brick foundations naturally weaken as mortar joints decay, tie-rod holes rust out, and block cavities collect moisture, creating new leak paths that didn\u2019t exist when the home was built,\u201d explains Tracy.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">That is why early detection is key. Musty odors, damp walls, flaking paint, or poor drainage around the home are not cosmetic issues. They are warning signs. Robin Ekloff, owner of <\/span><a href=\"http:\/\/johnswaterproofing.com\/\" data-wpel-link=\"external\" target=\"_blank\" rel=\"external noopener noreferrer\"><span style=\"font-weight: 400;\">John\u2019s Waterproofing Company<\/span><\/a><span style=\"font-weight: 400;\"> in <\/span><a href=\"https:\/\/www.redfin.com\/city\/17327\/OR\/Silverton\" data-wpel-link=\"exclude\"><span style=\"font-weight: 400;\">Silverton, OR<\/span><\/a><span style=\"font-weight: 400;\">, puts it plainly, \u201cWhen looking at a concrete foundation, it isn\u2019t a matter of <\/span><b>IF<\/b><span style=\"font-weight: 400;\"> it will leak, but <\/span><b>WHEN<\/b><span style=\"font-weight: 400;\"> it will leak.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Regular inspections and proactive maintenance go a long way in long-term water damage prevention, especially for below-grade spaces.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">2. Know your main shutoff valve<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">When a pipe bursts, seconds matter. Gary from <\/span><a href=\"http:\/\/raleighplumbing.com\/\" data-wpel-link=\"external\" target=\"_blank\" rel=\"external noopener noreferrer\"><span style=\"font-weight: 400;\">Raleigh Plumbing &amp; Heating<\/span><\/a><span style=\"font-weight: 400;\"> stated one of the most common issues they encounter is homeowners not knowing where their main shutoff valve is located. \u201cWhen water has been running for 10\u201320 extra minutes because no one could find the valve, the repair changes from cleanup to reconstruction.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">That extra time can mean thousands of dollars in damage:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Locate and label your main shutoff valve<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Show everyone in the household how to use it<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Test it once a year so it does not seize<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Keep it accessible, not buried behind storage<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Older valves can lock up due to mineral buildup, so testing it annually is part of smart water damage prevention.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">3. Replace aging supply lines before they fail<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Many homeowners expect leaks to start slowly. In reality, some of the worst failures happen suddenly. Gary mentions that one of their most frequent emergency calls involves supply lines under sinks or toilets splitting without warning.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In older homes, they regularly find:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Aging braided lines past their service life<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Lines weakened by cleaning supplies or storage under sinks<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Corrosion at shutoff connections<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">These parts are inexpensive to replace, yet they are responsible for significant interior damage when they fail. Swapping them out proactively is a simple <\/span><a href=\"https:\/\/www.redfin.com\/blog\/the-most-underrated-home-upgrades\/\" data-wpel-link=\"exclude\"><span style=\"font-weight: 400;\">upgrade<\/span><\/a><span style=\"font-weight: 400;\"> with major protective value.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you are wondering how to prevent water damage in an older house, this is one of the easiest starting points.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">4. Check your water pressure<\/span><\/h2>\n<p><a href=\"https:\/\/www.redfin.com\/blog\/does-this-house-have-good-water-pressure\/\" data-wpel-link=\"exclude\"><span style=\"font-weight: 400;\">Water pressure<\/span><\/a><span style=\"font-weight: 400;\"> that feels great in the shower might be quietly stressing your plumbing. Gary explains, \u201cMunicipal pressure today is much higher than what many older homes were built for.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">High pressure can:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Create hidden leaks<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Wear out fixtures and valves<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Shorten water heater life<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Turn minor weaknesses into sudden failures<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Normal pressure should range between 45\u201365 PSI. If your home tests higher than that, installing a pressure reducing valve can prevent long-term strain on your pipes.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This is one of the most overlooked aspects of water damage prevention in older homes.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">5. Do a quick walkthrough twice a year<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Most water problems give subtle warnings first. The problem is homeowners rarely look closely enough to catch them. Catching these early often means a small <\/span><a href=\"https:\/\/www.redfin.com\/blog\/diy-home-repairs\/\" data-wpel-link=\"exclude\"><span style=\"font-weight: 400;\">diy home repair<\/span><\/a><span style=\"font-weight: 400;\"> instead of a full renovation. Gary recommends a simple five-minute check a couple of times a year and suggests you look for:<\/span><\/p>\n\n<table id=\"tablepress-143\" class=\"tablepress tablepress-id-143\">\n<thead>\n<tr class=\"row-1\">\n\t<th class=\"column-1\"><br \/>\nAround Toilets<\/th><th class=\"column-2\">Under Sinks<\/th><th class=\"column-3\">At the Water Heater<\/th>\n<\/tr>\n<\/thead>\n<tbody class=\"row-striping row-hover\">\n<tr class=\"row-2\">\n\t<td class=\"column-1\">Slight rocking<\/td><td class=\"column-2\">Musty smells<\/td><td class=\"column-3\">Rust forming at the base<\/td>\n<\/tr>\n<tr class=\"row-3\">\n\t<td class=\"column-1\">Cracked or separated caulk<\/td><td class=\"column-2\">Dark or stained cabinet bottoms<\/td><td class=\"column-3\">Damp or corroded fittings<\/td>\n<\/tr>\n<tr class=\"row-4\">\n\t<td class=\"column-1\">Soft flooring<\/td><td class=\"column-2\">Minor corrosion<\/td><td class=\"column-3\">Expansion tank issues<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n<p><b><i>Read&gt;&gt; <\/i><\/b><a href=\"https:\/\/www.redfin.com\/blog\/can-you-sell-a-house-with-water-damage\/\" data-wpel-link=\"exclude\"><b><i>Can You Sell a House with Water Damage?<\/i><\/b><\/a><\/p>\n<h2><span style=\"font-weight: 400;\">6.

Some insurance companies even require them or offer discounted rates for installation.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For older homes, these systems add a layer of protection that did not exist when the property was built.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">7.

Over time, this can lead to settling, pipe movement, and leaks that appear to be plumbing failures but actually began outside.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Kewin Greenhill emphasizes, \u201cTo protect an older home\u2019s integrity, the most important rule is to keep water moving away from the structure. Ensure your gutters are cleared quarterly and that downspouts extend at least six feet from the foundation to prevent basement seepage or slab erosion.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To improve exterior protection:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Clean gutters at least quarterly<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Extend downspouts at least six feet from the foundation<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Avoid major landscaping changes that redirect water toward the house<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Check that grading slopes away from the home<\/span><\/li>\n<\/ul>\n<h2><span style=\"font-weight: 400;\">The bottom line<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Older homes require a little more attention, but they do not have to come with constant water issues.
