Depending on the agreed service, our deep-cleaning priorities can include:
Kitchen
- Grease around stove and rangehood
- Inside oven and microwave
- Cabinet fronts and handles
- Splashbacks and bench detail
Bathrooms
- Grout and tile detail
- Soap scum and limescale
- Behind toilets, extractor fans
- Corners a quick clean misses
Living & bedrooms
- Skirting boards, light switches
- Furniture-accessible surfaces
- Window sills, door frames
- Floor detail by floor type
High-touch & hard-to-reach
- Handles, switches, remotes
- Behind & under furniture (where accessible)

Welcome to QualGroup Cleaning Service
How QualGroup approaches residential deep cleaning differently
QualGroup was started in 2014 by Vijo Madappilly Jose and Riya Cherian, who between them bring 20+ years of healthcare experience — nursing, infection prevention and infection control — from before they built a cleaning company. That background matters more than it might sound.
In healthcare, cleaning isn’t judged on whether a surface looks clean — it’s judged on whether it actually is, because the consequences of getting it wrong are serious. That’s a different mindset to “wipe it until it looks fine,” and it’s the mindset our founders brought into QualGroup: prioritising the areas and surfaces that matter most for hygiene, being deliberate about high-touch points, and building a repeatable process instead of relying on individual cleaners doing their own thing.
For a home, that translates into practical differences: which areas get prioritised, how thoroughly high-touch points are treated, and how consistently the job is done, regardless of which specialist is assigned to it. It’s also why we’re upfront when something is outside the scope of a standard deep clean — a genuinely hygiene-focused approach means telling you the truth about what a service can and can’t achieve, not overselling it.
The Five Principles Behind Every Clean
- Healthy Cleaning
- Ethical Cleaning
- Hygienic Cleaning
- Secure Cleaning
- Sustainable Cleaning
Our High-Performance Cleaning (HPC) Methodology
High-Performance Cleaning: Applying a Structured Approach
A deeper clean is not simply about spending more time cleaning. QualGroup’s High-Performance Cleaning (HPC) Methodology provides a structured approach designed to improve cleaning effectiveness, consistency, sustainability and quality across your home.
Our HPC methodology brings together professional processes, appropriate cleaning solutions, quality checks and trained cleaning practices to deliver a more consistent result.
- Non-Toxic Cleaning Solutions
- TGA-Approved Disinfectants
- Hospital-Grade Standard
- UV Fluorescence Quality Audits
- Proprietary HPC System
| Regular Cleaning | Deep Cleaning | |
|---|---|---|
| Primary purpose | Ongoing maintenance | Condition reset / detailed clean |
| Frequency | Weekly, fortnightly, monthly | One-off, periodic, or condition-based |
| Scope | Routine, easily accessible areas | Detail areas, build-up, neglected spots |
| Starting condition | Already reasonably maintained | Needs additional attention |
| Level of detail | Routine pass | More intensive, area-by-area |
| Best suited to | Keeping a clean home clean | Establishing (or re-establishing) a clean baseline |
What Affects Scope, Time and Pricing
A deep clean isn’t a single fixed product, and any company that quotes one flat price without asking about your home is skipping a step. Scope, time and cost are shaped by several factors. We’ll ask about these before quoting so the price you’re given reflects your actual home, not a generic average. If, once our team is on site, the property genuinely needs more work than the original scope covered, we’ll talk to you about it before doing anything extra — not add it to the invoice as a surprise.
- Property size & rooms — Larger homes and additional rooms generally require more cleaning time.
- Current condition — Heavier neglect or long gaps between cleans can increase the work involved.
- Built-up dirt & grime — Grease, dust and residue levels can vary considerably between homes.
- Furniture & belongings — More items can require additional time to work around or move safely.
- Property access — Stairs, parking and internal access can affect how efficiently the team can work.
- Cleaning priorities — Full-home cleaning takes a different scope from selected rooms or priority areas.
- Surfaces & appliances — Different floors, fixtures and appliances may require specific cleaning methods.
- Specialist cleaning needs — Carpets, upholstery, tiles or other specialist work may require separate pricing.

Frequently Asked Questions
What is residential deep cleaning?
Residential deep cleaning is a detailed, condition-focused clean for areas that need more attention than routine cleaning provides. QualGroup delivers this across New Zealand using its High Performance Cleaning (HPC) approach.
What's the difference between deep cleaning and regular cleaning?
Regular cleaning maintains your home; deep cleaning resets it. QualGroup assesses the property’s condition, build-up and priorities to determine the appropriate scope.
What does a deep house clean include?
It can cover kitchens, bathrooms, bedrooms, living areas, floors, high-touch surfaces and often-missed areas. QualGroup tailors the scope to your home’s size, condition and requirements.
How often should you deep clean a house?
There is no fixed schedule. An annual or seasonal reset may suit some homes, while others may need deep cleaning after renovation, moving or a long gap in professional cleaning.
How much does deep cleaning cost in NZ?
Pricing depends on your home’s size, condition, access and cleaning requirements. With 1,700+ cleaning projects completed, QualGroup provides quotes based on the actual scope rather than a one-size-fits-all rate.
How long does a deep clean take?
It depends on the property’s size, condition and agreed scope. QualGroup will provide a realistic time expectation when discussing your requirements.
Is deep cleaning suitable for occupied homes?
Yes. QualGroup regularly provides residential cleaning for occupied homes; let us know about pets, children, routines or access requirements when booking.

Yes, where available. These are specialist services with different cleaning methods and equipment; QualGroup has 39+ specialist machines and equipment to support different cleaning requirements.
What should I do before a deep clean?
You don’t need to clean beforehand. Simply clear valuables and excessive clutter where practical, and tell QualGroup about pets, access requirements and priority areas.
Does deep cleaning disinfect the whole house?
No. Cleaning and disinfection are different services. QualGroup’s HPC methodology incorporates infection-prevention principles and appropriate disinfectant use where relevant.
Why is QualGroup different?
QualGroup combines 12+ years of professional cleaning experience with healthcare-informed expertise. Its founders bring 20+ years of combined experience in nursing, infection prevention and infection control, supported by HPC and structured training through QualClean Academy, established in 2020.
