Unexplained increases in your monthly water bill, warm spots under concrete flooring, damp carpets, or the sound of running water when all fixtures are turned off are key indicators of a hidden leak. You may also notice reduced water pressure or sudden cracks in foundation walls.
A slab leak occurs when a fresh water supply line or underground drainage pipe beneath your home’s concrete slab foundation ruptures or develops corrosion. Because the piping is buried under concrete, unaddressed slab leaks can erode surrounding soil, shift foundation footings, and damage internal flooring.
Hydrostatic testing is a diagnostic pressure test used to confirm whether a property’s under-slab sanitary sewer or drainage system is watertight. Technicians isolate the main sewer line at the property perimeter, fill the system with water to grade, and monitor water level stability over a controlled period. Learn more on our dedicated Hydrostatic Testing page.
Hydrostatic pressure testing is typically recommended during real estate transactions, after significant foundation leveling, or when homeowners observe signs of foundation movement alongside drainage slowdowns. It provides verifiable proof of whether underground drain lines are holding water pressure or leaking into foundation soil.
No. Hydrostatic testing specifically evaluates the under-slab drainage and sanitary sewer network. Fresh water supply line leaks are diagnosed using separate high-sensitivity acoustic tracing and thermal imaging equipment.
A main line clog affects your entire home rather than a single sink or toilet. Common warning signs include multiple fixtures backing up simultaneously, water rising into shower stalls when a toilet is flushed, or persistent gurgling noises coming from floor drains.
Recurring backups often indicate a deeper restriction in your main sewer line rather than a localized fixture clog. Tree root intrusion, grease buildup, offset pipe joints, or sagging sewer lines accumulate debris over time, rapidly closing off full pipe drainage. Restoring proper flow frequently requires a professional Main Sewer Line Replacement.
A main line cleanout is an accessible exterior pipe fitting connected directly to your main sewer lateral. It provides a direct access point for technicians to insert heavy-duty drain cleaning cables or high-pressure hydrojetting equipment to clear major sewer blockages safely outside your home.
You should schedule a sewer camera inspection if you experience repeated drain backups, smell persistent sewer gas indoors, notice wet patches in your yard, or are purchasing an older property. Exploring your lines with an HD camera provides clear visual proof of what is inside the pipe.
Yes. A high-definition Sewer Camera Inspection travels inside your underground pipes to capture real-time video footage of root penetrations, cracked clay lines, collapsed PVC joints, corrosion buildup, and foreign object blockages.
Indications of damaged sewer piping include recurring main line backups, localized sinkholes or soggy patches in the lawn, persistent sewer odors outside, and pest infestations near drain lines.
Not always. Some recurring clogs are caused by grease or heavy paper accumulation that can be resolved with thorough cleaning or hydrojetting. However, if root intrusion or pipe collapse is causing the obstruction, structural repairs will be necessary.
Technicians conduct a sewer video camera inspection to evaluate structural integrity. If the pipe wall is intact and structurally sound, clearing the blockage restores full function. If the camera reveals crushed, offset, or broken pipe walls, a targeted [Sewer Line Repair] is recommended.
No. Depending on the extent and location of the damage, targeted spot repairs can fix isolated pipe sections without requiring a full sewer lateral replacement. A professional video evaluation determines the most cost-effective solution for your property.
Immediately shut off the main water isolation valve to prevent continuous property damage. Once the water flow is stopped, turn off power to electrical appliances near the leak and contact a licensed professional for repair assistance.
Sudden drops in household water pressure can result from municipal supply fluctuations, mineral scale buildup inside older lines, malfunctioning pressure reducing valves (PRV), or hidden water leaks in your plumbing system.
Hot water loss can stem from a tripped circuit breaker, a extinguished gas pilot light, a failed heating element, or excessive sediment accumulation inside the tank. Review our Water Heater Installation, Repair & Replacement page for repair and replacement details.
You should contact a licensed professional whenever a repair involves main water supply lines, gas connections, under-slab drainage, concealed wall leaks, or severe sewer backups. DIY attempts on complex mechanical systems can cause secondary water damage and violate local plumbing codes.
An air conditioner that runs without lowering room temperature may have dirty air filters, frozen evaporator coils, a clogged condensate line, low refrigerant levels, or outdoor condenser unit airflow restrictions.
HVAC systems should receive professional maintenance twice per year, an AC checkup in early spring before Texas summer heat arrives, and a heating system tune-up in early autumn.
Request professional AC & Heating Services if your system blows warm air during cooling cycles, makes grinding or squealing noises, rapidly cycles on and off, or causes sudden spikes in your energy bills.
