Being able to identify hidden leaks behind your walls or under your floors can help prevent serious problems down the line. If you notice any worrisome signs, then you should reach out to a plumber in Boca Raton as soon as possible for plumbing leak detection. Contact Broward Plumbing today!
Here are some signs that you may have a hidden leak in your home.
Plumbing-Related Signs of a Leak Behind Your Walls
One of the most common places where there may be hidden plumbing leaks in your home is behind your walls, as numerous plumbing pipes run beneath your walls. Here are some common signs of leaks behind walls.
Water Stains or Discoloration
When water makes contact with drywall, you may notice yellow or brown discoloration. These may be found on your ceilings or on the upper ceilings throughout your home.
Peeling, Bubbling, or Warped Wall Surfaces
Moisture from leaking pipes causes paint, plaster, or drywall to deteriorate. You may notice that your drywall begins to bubble, and these are generally filled with water, so ensure that you do not touch them. Simply call a plumber in Boca Raton.
Persistent Musty or Damp Odors
Excess moisture from plumbing leaks provides the perfect environment for mold growth. Mold can grow in as little as two days after a leak, after which you may begin to notice a damp or musty odour in your home.
Dripping or Hissing Sounds in the Walls
Sometimes, slow leaks can produce a slight hissing or dripping sound behind your walls. This is the sound of water leaking out of your pipes.
Plumbing-Related Signs of a Leak Under Your Floors
Believe it or not, plumbing pipes are also located beneath your floors, and plumbing leaks may also happen beneath the surface. Here are some signs of leaks under your floors.
Warm Spots on the Floor
Sometimes hot water lines run underneath flooring, and when they leak, you may notice random warm spots on your floors.
Soft, Spongy, or Buckling Floors
Wood or laminate flooring absorbs water from leaks below very easily. This can result in soft, spongy floors that may even become warped.
Loose Tiles or Cracked Grout
Leaks from below your floors can dampen floor adhesive, leading to loose tiles and/or cracked grout.
