Nest Fumigation Services runs a commercial cleaning operation for Karachi businesses — offices, retail floors, clinics, restaurants, and schools — covering scheduled janitorial contracts, periodic deep cleaning, post-construction handover cleaning, and disinfection, all documented for audit files. We work on annual maintenance contracts with defined scopes and service levels, schedule the disruptive work after hours, and hand over a paper trail your compliance auditor will accept. This is the B2B side of our cleaning business. If you are a homeowner, our residential-leaning cleaning services hub is the right starting point; this page is for facilities managers, procurement officers, and business owners buying cleaning as a contract. I am Saad Danish, founder of NFS, and we run both our pest and cleaning operations from the same DHA Phase 4 office.
What commercial cleaning covers
Commercial cleaning is not one service — it is a set of distinct scopes a business buys separately or bundles into a contract. Each has different frequency, equipment, and documentation needs.
Scheduled janitorial and facility cleaning
The daily or several-times-weekly backbone: floors, washrooms, common areas, reception, pantry, glass, and waste handling on a fixed rota. This is contract work, not a one-off — a defined scope, a defined frequency, and a supervisor accountable for it. We staff it against a checklist so that "clean" is a specification, not an opinion, and the same standard holds whether or not anyone is watching that shift. Washroom hygiene gets particular attention because it is the single area where a lapse is most visible to your staff and customers.
Commercial deep cleaning
Periodic top-to-bottom cleaning that daily janitorial cannot reach: high dusting of ceilings, ducting exteriors, and light fittings; degreasing of kitchen and pantry surfaces; descaling of washroom tile and fittings against Karachi's hard water; floor stripping and re-sealing; and detailed work on partitions, blinds, and upholstery. Offices book this quarterly or half-yearly; food premises and clinics need it more often. We run commercial-grade hot-water extractors, rotary scrubbers with the correct pad grade, and alkaline degreasers (pH 11–12) for cooked-on grease rather than one all-purpose product that half-works on everything.
Post-construction and handover cleaning
The specialist clean between "builders finished" and "we move in". Post-construction debris is different from ordinary soil: cement film and grout haze on tiles and glass, plaster and paint spatter, silicone smears, fine construction dust that has settled into every duct and cavity, and adhesive residue. It needs an alkaline strip for cement film, careful blade and solvent work on glass, and a staged dust removal — high surfaces first, then a full re-clean once airborne dust has resettled — because a single pass just moves the dust around. We handle handover cleans for new offices, fitted-out retail units, and completed floors, and quote after a site walk because condition varies enormously.
Disinfection and sanitisation
Surface disinfection for clinics, dental practices, restaurants, schools, and offices during illness season or after a case. We use quaternary ammonium compounds and sodium hypochlorite at labelled dilutions with the required contact time — disinfection only works if the surface stays wet for the product's stated dwell, which is the step most casual cleaning skips. High-touch points (door handles, switches, lift buttons, shared equipment, counters) are the priority. This ties naturally to the pest side of our business: a food or healthcare premises usually needs both surface disinfection and pest control on the same compliance schedule.
Who we clean for in Karachi
Different premises carry different standards, and we scope the contract to match.
- Offices and corporate floors — daily janitorial plus quarterly deep cleaning, scheduled around working hours so the disruptive work happens after close or before open.
- Retail and showrooms — glass, floors, and front-of-house presentation held to a customer-facing standard, with restocking-hour or pre-open scheduling.
- Clinics and dental practices — disinfection-led cleaning with documented contact times, high-touch focus, and waste-area discipline. We do not present ourselves as a clinical sterilisation service; we provide facility cleaning and surface disinfection to support your own infection-control protocol.
- Restaurants and cafés — kitchen degreasing, hood and tile work, and front-of-house cleaning aligned to Sindh Food Authority [1] expectations, plus the pest control most food businesses need on the same visit cycle.
- Schools and offices with high footfall — deep cleaning during holidays and term breaks, disinfection during flu and gastro season.
How commercial cleaning contracts work
Buying cleaning as a business is different from booking a one-off home clean. The value is in the contract structure, not just the mopping.
AMC and scope of work
We work on annual maintenance contracts with a written scope: exactly which areas, at what frequency, to what standard, with which tasks daily, weekly, monthly, and quarterly. A defined scope is what stops the slow erosion where a contract quietly shrinks to whatever the crew felt like doing. You know what you are paying for, and we know what we are accountable for.
Service levels and supervision
Each contract names a supervisor and a response standard — how quickly we act on a complaint, how a missed task is made good, how staffing is covered when someone is off. Cleaning quality drifts without supervision; the SLA is what holds it. For larger sites we run periodic quality checks against the scope checklist rather than waiting for you to notice a problem.
After-hours and weekend scheduling
The disruptive work — floor machines, deep cleaning, disinfection fogging — is scheduled outside your operating hours: early morning before open, evening after close, or weekends. For most Karachi offices and retail floors we build this into the contract at no premium, because doing it around your business is simply part of doing it properly.
Documentation for audits
For food businesses, clinics, and any premises facing an audit, we provide a documentation trail: dated service records, the chemicals and dilutions used, disinfection contact times, and — where cleaning is bundled with pest control — sanitisation and pest-management certificates for your compliance file. We help our clients document to HACCP, ISO 22000, and WHO-GMP expectations; to be precise, that means we produce the cleaning and pest records those systems require, not that NFS itself holds those certifications.
Cleaning bundled with commercial pest control
The strongest reason to run both with one contractor is the overlap. A restaurant, food plant, pharmacy, warehouse, or clinic needs surface hygiene and pest control on the same premises, often on the same audit schedule, and split vendors mean two sets of visits, two paper trails, and gaps where each assumes the other handled something. We run commercial pest control in Karachi from the same office and the same quality system, so a single contract can cover scheduled janitorial, periodic deep cleaning, disinfection, and pest management with one supervisor and one consolidated compliance file. For food premises especially, the sanitation-and-pest pairing is how audits are actually passed. General fogging and space treatment run through our disinfestation and general spray service.
Commercial cleaning pricing in Karachi
Commercial cleaning is quoted after a site walk, not from a fixed rate card, because floor area, footfall, surface types, fitting count, and required frequency move the price too much to publish a single number. What we can tell you is how it is structured:
- Scheduled janitorial is priced per month against the agreed scope and frequency — a small office on three-times-weekly service costs very differently from a retail floor needing daily coverage.
- Commercial deep cleaning is priced per visit by area and condition, typically booked quarterly or half-yearly, with a lower per-visit rate inside an AMC than as a one-off.
- Post-construction handover is quoted per project after a site walk, because cement-film and debris load vary enormously between a bare shell and a fitted-out unit.
- Disinfection is priced per area and per visit, or folded into a janitorial contract as a scheduled line.
AMC contracts carry a per-visit discount over one-off booking and lock your rate for the year. For the residential rate card and bundle logic, see our Karachi pricing pillar. To scope a commercial contract, we come to you — a free site walk is the only honest way to quote this work.
Why businesses pick NFS for commercial cleaning
The honest answer is cross-vertical trust and a real quality system. NFS has run pest and cleaning operations from this DHA Phase 4 office since 2024, holds ISO 9001:2015 certification on the live registry, and is a member of the Karachi Chamber of Commerce & Industry (KCCI), the Structural Pest Management Association (SPMA), and the Pakistan Pest Management Association (PPMA). Our Google Business Profile is two years old at 175 verified reviews. We run commercial-grade equipment — hot-water extractors, rotary scrubbers, correct pad grades, and labelled disinfectant chemistry — not consumer gear, and we are transparent about what each product is and the safety data sheet behind it. And because we already run commercial pest control, we understand the audit and compliance world our B2B clients live in, which a general cleaning company usually does not.
Frequently Asked Questions
How much do commercial cleaning services cost in Karachi?+
Commercial cleaning is quoted after a site walk rather than from a fixed price, because floor area, footfall, surface types, and required frequency drive the cost. Scheduled janitorial is priced per month against the agreed scope; deep cleaning and post-construction handover are priced per visit or per project by area and condition; disinfection is priced per area. Annual maintenance contracts carry a per-visit discount and lock your rate for the year. Email contact@nestfumigationservices.com or call +92-311-1101810 to arrange a free scoping visit.
What is the difference between janitorial and deep cleaning?+
Janitorial is the recurring daily or several-times-weekly maintenance — floors, washrooms, common areas, waste — that keeps a premises presentable on a fixed rota. Deep cleaning is the periodic top-to-bottom work that daily cleaning cannot reach: high dusting, degreasing, descaling, floor stripping and sealing, and detailed upholstery and fitting work, using commercial extractors and scrubbers. Most Karachi offices run daily janitorial plus quarterly or half-yearly deep cleaning; the two complement each other rather than substitute.
Can you clean after office hours or on weekends?+
Yes. The disruptive work — floor machines, deep cleaning, disinfection — is scheduled outside your operating hours, whether early morning before open, evening after close, or weekends. For most office and retail contracts we build after-hours scheduling in at no premium, because doing the work around your business is part of doing it properly. Daily janitorial timing is agreed in the contract to suit your operating pattern.
Do you provide documentation for food safety or ISO audits?+
Yes. For food premises, clinics, and audited businesses we provide dated service records, the chemicals and dilutions used, disinfection contact times, and — where cleaning is bundled with pest control — sanitisation and pest-management certificates for your compliance file. We help clients document to HACCP, ISO 22000, and WHO-GMP expectations, meaning we produce the cleaning and pest records those systems require. To be clear, NFS holds ISO 9001:2015 itself; we support your certifications, we do not claim to hold HACCP or ISO 22000 on your behalf.
What does post-construction cleaning involve?+
Post-construction cleaning removes the specific mess builders leave: cement film and grout haze on tiles and glass, plaster and paint spatter, silicone smears, adhesive residue, and fine construction dust settled into ducts and cavities. It needs an alkaline strip for cement film, careful blade and solvent work on glass, and staged dust removal — high surfaces first, then a full re-clean once airborne dust resettles, because one pass only redistributes it. We quote handover cleans per project after a site walk, since condition varies from a bare shell to a fitted-out unit.
Do you offer cleaning and pest control together?+
Yes, and for commercial premises that is the point. A restaurant, food plant, pharmacy, warehouse, or clinic needs both surface hygiene and pest control, usually on the same audit schedule, and splitting them across vendors creates gaps and duplicate paperwork. We run both from the same DHA Phase 4 office under one quality system, so a single contract covers janitorial, deep cleaning, disinfection, and pest management with one supervisor and one consolidated compliance file. For food businesses, the sanitation-and-pest pairing is how audits are passed.
