Home Maintenance Services

Plumbing Pipeline Repair and Replacement
Plumbing maintenance is the most frequent household service, covering water supply, drainage and waterproofing problems that affect daily living. Common routine repairs include fixing dripping faucets, blocked kitchen sinks and clogged toilet sewage pipes, which are usually caused by grease accumulation, foreign object blockage or aging internal pipeline components. Professional maintenance workers use high-pressure water dredgers and pipeline cameras to locate internal blockages without damaging indoor floor tiles. For aging pipelines with long-term corrosion, technicians replace rusted hot and cold water pipes and seal pipe joints to prevent hidden water leakage. Besides indoor pipelines, the service also includes balcony and roof waterproof maintenance. Many household roof leaks stem from cracked waterproof coatings and loose seam fillers; workers will clear accumulated rainwater, repair crack gaps and reapply high-elastic waterproof materials. All plumbing repairs include post-maintenance water pressure testing to ensure no secondary leakage within one month after completion.

Household Circuit and Electrical Equipment Maintenance
Electrical maintenance focuses on safe troubleshooting of low-voltage household circuits and small electrical fixtures, excluding high-voltage outdoor power facilities. Typical service items cover tripping circuit breakers, loose wall sockets, damaged indoor light switches and faulty ceiling lamp wiring. Most hidden electrical risks come from aging wire insulation layers and overloaded circuit load, which easily trigger short circuits and household fires. Professional maintenance personnel first cut off household main power to eliminate electric shock risks, then use multimeter tools to detect circuit short-circuit points and replace aging copper wires. The service also includes debugging built-in home appliances such as exhaust fans, water heaters and range hoods. Technicians check grounding wire connectivity for electric water heaters to prevent electric leakage accidents. Unlike amateur self-repair, formal electrical maintenance follows residential electrical safety codes and provides written safety inspection reports for users after finishing repairs.

Door, Window and Hardware Structural Maintenance
Doors, windows and supporting hardware are prone to loosening and deformation after long-term use due to seasonal temperature changes and frequent friction. Common failures include stuck sliding window tracks, sagging interior wooden doors, noisy door hinges and broken window sealing strips. For deformed aluminum alloy windows, workers adjust track pulleys and correct window frame angles to solve jamming and poor closing problems. Worn rubber sealing strips will be fully replaced to block outdoor wind, dust and noise leakage, improving household thermal insulation. For wooden doors with loose hinges and sagging door panels, technicians tighten fixing screws and add buffer gaskets to avoid door bottom friction with the floor. Additional hardware maintenance includes lock cylinder replacement, door closer debugging and balcony railing reinforcement. For cracked window glass, the team provides on-site glass cutting, replacement and edge sealing to avoid secondary breakage and personal injury risks.

Indoor Wall, Floor and Ceiling Repair
Indoor surface maintenance solves cosmetic and structural damage caused by moisture, mildew and foundation settlement. Wall problems include peeling latex paint, water stain discoloration, mold growth and wall cracks. For shallow surface damage, workers polish moldy areas, apply anti-mold primer and repaint matching wall paint to keep consistent indoor color. For deep penetrating wall cracks caused by minor foundation settlement, reinforcement mesh will be embedded before repainting to prevent repeated cracking. Floor maintenance covers ceramic tile hollowing, loose floor gaps and scratched solid wood floors. Hollowed tiles are removed and re-bonded with special tile adhesive, while wooden floors undergo gap filling and surface waxing to prevent moisture deformation. Ceiling maintenance mainly targets sagging gypsum board ceilings and cracked sealing joints, which are reinforced with keel supports to avoid ceiling collapse accidents.

Smart Home Equipment Debugging and Maintenance
With the popularity of residential intelligence, smart home maintenance has become a mainstream customized household service. It includes debugging wireless smart doorbells, sensor-based lighting systems, automatic curtain motors and indoor air monitoring devices. Most smart home failures are not hardware damage but network matching errors and parameter setting mistakes. Professional maintenance staff re-match local Wi-Fi networks, reset equipment protocols and repair faulty sensor probes. For integrated smart water and electricity monitoring terminals, technicians calibrate abnormal data deviation and replace built-in low-power batteries. The service also covers interconnection debugging between cross-brand smart devices, solving incompatibility problems between different system products. Regular quarterly smart equipment maintenance can reduce equipment failure rates by nearly 40% and extend the service life of indoor intelligent hardware.

Service Pricing and Safety Precautions for Users
Users need to clarify pricing rules and risk guidelines to avoid overcharging and post-repair safety hazards. Formal home maintenance adopts two pricing modes: fixed-price routine repairs for simple tasks such as faucet replacement and time-based billing for complex hidden pipeline troubleshooting. Standardized service teams provide transparent pre-repair quotations with no hidden fees for secondary material charges. In terms of safety, users should verify worker identity certificates and personal accident insurance before on-site maintenance, as informal workers lack accident liability guarantees. After repair, users need to check finished quality and ask for a 90-day after-sales warranty for labor faults. Meanwhile, users should avoid temporary random modifications to load-bearing walls, indoor main circuits and sewage main pipes, as unauthorized changes violate residential building regulations and trigger potential structural risks.
