Signs of A Slab Leak in Newcastle
It isn't always easy to differentiate a concrete slab leak from a few other plumbing problems that can occur, making diagnosis tricky at times. However, there are symptoms that the crew at Seattle's Plumbing LLC looks for to determine the nature of your Newcastle foundational leak.
- Hearing running water sounds - Water silently travels through underground pipes. If you hear the sound of running water and don't have a faucet running, this is a sign of a leak.
- Dampness or wet spots on your floor - You may see slightly darker spots or even small puddles depending on the size and type of leak
- Spike in your water bill - Higher bills commonly indicate a leak somewhere in the home, but do not determine the source
- Presence of Mold or mildew - When the foundation is moist for more than a few days, it creates a ripe breeding ground for microbes
- Cracks in the foundation - Buckling and/or cracks appearing outside on your home's foundation or on interior floors indicate a leak
