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

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.

Deep Cleaning vs Regular Cleaning
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.

The exterior house clean service provided by QualGroup was excellent and reasonably priced. The team worked efficiently and carried out a thorough job. The house was sparkling after they had finished. We would have no hesitation using QualGroup again or recommending them for a house clean.
We are very fortunate and pleased with the cleaning services provided b y Harriet and the Customer Service we receive from Roland at QualGroup. The standard of cleaning is consistently excellent, and the office always feels fresh, tidy, and welcoming for both staff and visitors.
We truly appreciate the care taken in maintaining our workspace and would highly recommend their services to anyone looking for a thorough and dependable cleaner.
What a great job done, it’s one of those jobs I have half pie always done for myself but never managed to get it done properly or fully. To see all my gutters clean inside and out along with the roof and house with soft wash done, and looking so good was honestly like having a load taken off my shoulders and add to that the spider spray done means I won’t have the worry of the pesky white tails I seem to get in the house thru summer. I have never ever seen the exterior of my house look so clean and tidy. Simple easy communication from quote thru to completion of the job. Thanks guys I’ll book again next year

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.

Regular cleaning maintains your home; deep cleaning resets it. QualGroup assesses the property’s condition, build-up and priorities to determine the appropriate scope.

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.

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.

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.
