Professional Disinfection and Sanitization Services in Delhi NCR
Maintaining a genuinely safe, hygienically clean environment requires more than routine surface cleaning. Regular household and commercial cleaning removes visible dirt and debris but does not eliminate the pathogenic microorganisms — viruses, bacteria, fungi, and spores — that cause illness and create health risks for occupants and staff. Professional disinfection uses approved biocidal agents applied by trained technicians using equipment that ensures comprehensive coverage of all surfaces, including hard-to-reach areas that routine cleaning misses.
SKUAS Pest Control provides hospital-grade disinfection and sanitization services across Delhi NCR for residential homes, corporate offices, restaurants, schools, clinics, gyms, hotels, and commercial properties of all types. Our certified technicians use EPA and WHO-approved formulations applied via ULV fogging, electrostatic spraying, and targeted high-touch surface treatment to deliver broad-spectrum antimicrobial protection across your entire property. Services are available same-day, with minimal preparation required and fast re-entry times to minimize disruption to your routine.
When Do You Need Professional Disinfection?
Professional disinfection is appropriate — and often essential — in a wide range of situations:
- Post-COVID or respiratory illness outbreak: When confirmed COVID-19, influenza, or other respiratory illness cases have occurred in a home, office, or commercial space, professional disinfection using virucidal agents is the most reliable way to reduce viral load and protect remaining occupants and staff.
- Post-pest treatment disinfection: Following cockroach, rat, or bird infestation treatment, disinfection eliminates the pathogenic bacteria, fungi, and viruses deposited by the pest population in contaminated areas — particularly important in kitchens, food preparation areas, and storage rooms.
- New property occupation: Before moving into a new home or office — especially a previously tenanted property — professional disinfection provides peace of mind and a genuinely clean starting environment.
- Healthcare and food facility compliance: Clinics, hospitals, pharmacies, diagnostic laboratories, food processing units, and restaurant kitchens require regular professional disinfection as part of regulatory compliance (FSSAI, NABH, JCI, ISO 22000).
- Schools and childcare facilities: High-density child environments are particularly vulnerable to gastroenteritis outbreaks, hand-foot-mouth disease, and other infectious illnesses. Scheduled professional disinfection reduces the pathogenic load in classrooms, toilets, and common areas.
- Hotels and hospitality: High guest turnover means rapid transfer of pathogens between room occupancies. Professional disinfection of guest rooms and common areas — beyond standard housekeeping — reduces infectious disease transmission between guests.
- Post-flooding or water damage: Following water ingress from flooding, pipe bursts, or monsoon damage, affected areas require disinfection to prevent mold establishment and eliminate waterborne pathogens deposited by contaminated water.
- Gyms and fitness centers: High-contact surfaces in gyms (equipment, handles, benches) harbor bacteria and fungi that cause skin infections. Regular professional disinfection supplements daily cleaning for a genuinely safe member environment.
Our Disinfection and Sanitization Methods
ULV (Ultra Low Volume) Fogging
ULV fogging generates an ultra-fine mist of disinfectant droplets (5–30 microns) that remain suspended in the air and penetrate into every accessible corner, gap, ceiling void, and hard-to-reach surface throughout the treated space. Unlike manual spraying which is limited to accessible flat surfaces, ULV fogging achieves comprehensive coverage of the entire room volume — including air, wall surfaces, furniture undersides, ceiling areas, and behind equipment. This makes ULV fogging the most effective method for rapid, comprehensive disinfection of enclosed spaces. Our ULV equipment uses WHO-approved disinfectant formulations with broad-spectrum efficacy against enveloped viruses (including coronaviruses), non-enveloped viruses, gram-positive and gram-negative bacteria, and fungi.
Electrostatic Spraying
Electrostatic spraying uses electrically charged disinfectant droplets that are attracted to and wrap around surfaces with a natural cling effect, ensuring 360-degree coverage of complex, irregular surfaces that would be missed by conventional spray or wipe methods. It is particularly effective for disinfecting chairs, workstations, elevator interiors, gym equipment, and medical equipment. Electrostatic applicators are 50 times more efficient than manual spraying in terms of coverage per unit volume of disinfectant, reducing chemical consumption while achieving superior coverage. We use electrostatic spraying as the primary method for high-traffic commercial spaces, healthcare environments, and food facilities where comprehensive surface coverage is critical.
High-Touch Surface Disinfection Wipe-Down
ULV fogging and electrostatic spraying provide comprehensive environmental disinfection, but high-contact surfaces that are touched frequently throughout the day — door handles, light switches, lift buttons, tap handles, desk surfaces, computer keyboards, and handrails — require targeted manual wipe-down with an approved disinfectant-soaked cloth to ensure adequate contact time and full surface coverage. Our technicians perform a systematic high-touch surface wipe-down as part of every commercial disinfection service, working through a room-by-room checklist to ensure complete coverage of all critical contact surfaces.
Drain and Surface Mold Disinfection
Kitchen drains, bathroom grouting, AC drain trays, and damp wall surfaces frequently harbor mold (particularly Aspergillus and Cladosporium species) that trigger respiratory allergies and release mycotoxins. We use targeted fungicidal disinfectants on these surfaces as part of our residential and commercial disinfection programs, helping to prevent mold establishment in the post-monsoon period when humidity levels in Delhi NCR create ideal mold growth conditions.
Our Disinfection Process — Step by Step
Step 1: Site Assessment and Scope Definition
Our technician reviews the property layout, identifies all areas requiring treatment, notes any special requirements (sensitive equipment, aquariums, food storage areas), and advises on minimal preparation needed before treatment. For complex commercial properties (hospitals, food facilities, multi-floor offices), we provide a formal service scope document for review and approval before scheduling treatment.
Step 2: Pre-Treatment Preparation
You will need to do only minimal preparation — remove people and pets from the treatment area, cover aquariums and exposed food, and ensure the property is accessible. Our technician will advise on any specific additional preparation during the assessment call. Pre-treatment preparation typically takes less than 15 minutes for most residential and small commercial properties.
Step 3: ULV Fogging or Electrostatic Spray Application
Our technician systematically treats every room and accessible space using the ULV fogger or electrostatic sprayer, starting from the farthest point and working toward the exit to ensure complete coverage without re-entering treated areas. The disinfectant is applied at the correct concentration and application rate to achieve the product's specified log-reduction efficacy against target pathogens. Dwell time in each room is maintained as per the product's contact time requirements before proceeding to the next space.
Step 4: High-Touch Surface Wipe-Down
Following the fogging/spray application, our technician performs a systematic wipe-down of all identified high-touch surfaces throughout the property using a disinfectant-saturated microfiber cloth, maintaining the required contact time on each surface. This step ensures that frequently touched surfaces that receive high bacterial and viral contamination throughout the day are given particular attention beyond the general room disinfection.
Step 5: Re-Entry Clearance and Service Documentation
After treatment, our technician provides the re-entry guidance for your specific property and service. For most residential properties, re-entry is safe within 30–60 minutes after treatment. For food facilities and healthcare environments, we provide formal re-entry certification, treatment records specifying products used, concentration, application method, and coverage area — suitable for regulatory audit documentation.
Why Choose SKUAS for Disinfection in Delhi NCR
Disinfection Service Pricing

What to Expect After Disinfection Treatment
Understanding what happens after professional disinfection helps you get the best value from the service:
- Re-entry timing: For ULV fogging, keep all people and pets out of treated areas until the fog has fully settled — typically 30–60 minutes depending on property size and ventilation. Our technician will advise the specific re-entry time for your property based on the products used and space conditions.
- Disinfection reduces pathogen load but does not replace regular cleaning: Professional disinfection eliminates pathogens present at the time of treatment. Regular subsequent surface contamination from building use means that the disinfection treatment's protective benefit gradually diminishes. Regular cleaning and hygiene practices complement professional disinfection and extend its effective period.
- Ventilate after treatment: Once the re-entry time has passed, open windows and allow good ventilation through the property for 30–60 minutes before resuming normal operations. Good airflow reduces any residual product odor.
- Avoid mopping treated surfaces immediately: Wet mopping floor surfaces within a few hours of fogging treatment can remove product deposited on floor surfaces. Dry sweeping or dry mopping is preferable in the first few hours after treatment.
- Schedule repeat treatment based on use: For high-traffic commercial spaces, disinfection effectiveness diminishes faster. Our AMC programs are scheduled based on your property type and traffic levels to maintain consistent microbial control.
