What’s Included in a Professional Deep Cleaning Service

No matter how often your office or business premises are cleaned, there comes a time when regular cleaning just isn’t enough.
Dust builds up in corners, grime hides behind furniture, and certain spots get overlooked during daily routines. That’s where professional deep cleaning comes in — a thorough, top-to-bottom process that refreshes your entire workspace and restores hygiene standards to perfection.

If you’ve ever wondered what a deep clean actually includes — or how it differs from standard cleaning — this detailed guide will walk you through everything you need to know, featuring insights from Premier Contract Cleaning, one of Dublin’s most trusted names in commercial and office cleaning.

1. What Is a Deep Cleaning Service?

A deep clean goes far beyond the basics.
While a standard clean focuses on visible surfaces and high-traffic areas, deep cleaning reaches the hidden, hard-to-reach, and often-neglected spaces that accumulate dirt, bacteria, and odours over time.

Think of it like giving your workspace a complete reset — removing dust from vents, sanitising under furniture, scrubbing tiles, and restoring freshness everywhere.

At Premier Contract Cleaning, deep cleaning is one of their most popular services among Dublin businesses — perfect for offices, retail spaces, schools, healthcare clinics, and more. Their trained professionals use advanced equipment, eco-friendly products, and systematic checklists to ensure no corner is left untouched.

2. Why Deep Cleaning Is Essential for Businesses

It’s easy to assume that regular office cleaning is enough, but dirt builds up in layers. Even with daily or weekly maintenance, grime can accumulate in carpets, vents, and furniture.

Here’s why every business should schedule periodic deep cleans:

• Health and hygiene: Reduces allergens, bacteria, and dust mites that cause illness.

• Professional image: A spotless environment creates a positive impression on clients and employees.

• Odour control: Removes stale smells from carpets, upholstery, and kitchens.

• Long-term maintenance: Protects flooring, furniture, and fixtures from damage.

• Compliance: Supports businesses in hygiene-sensitive sectors (e.g. healthcare, education, food service).

Premier Contract Cleaning recommends scheduling deep cleaning at least twice a year — or quarterly for busy premises like offices, gyms, or showrooms.

3. What’s Included in a Professional Deep Clean

Now, let’s break down what you actually get when you book a professional deep cleaning service.
Each area of your workspace gets specialised attention — from floor to ceiling.

a. Office Areas and Common Rooms

• Thorough dusting of all surfaces (including light fixtures, vents, and skirting boards)

• Wiping and sanitising desks, chairs, and office equipment

• Deep cleaning of computer keyboards, monitors, and phones

• Vacuuming carpets and upholstered furniture

• Cleaning under and behind desks and cabinets

• Polishing metal and glass surfaces

• Wiping down doors, handles, and switches

• Cleaning windows (interior) and frames

Premier Contract Cleaning’s teams use safe, non-toxic disinfectants that kill 99.9% of bacteria while protecting surfaces — ideal for busy office environments.

b. Floors and Carpets

Floors bear the brunt of daily activity. Over time, they collect grime and bacteria that regular mopping can’t fully remove.

Deep cleaning includes:

• Scrubbing hard floors with industrial-grade machines

• Steam cleaning or shampooing carpets

• Removing stains and odours from rugs and mats

• Applying protective coatings (where needed)

• Sanitising baseboards and corners

Premier Contract Cleaning’s carpet cleaning service is especially popular in Dublin offices, using hot water extraction to lift dirt from deep within carpet fibres without damaging them.

c. Kitchens and Break Areas

Workplace kitchens can easily become breeding grounds for bacteria — especially in shared spaces.

Deep cleaning here involves:

• Degreasing kitchen appliances (microwave, fridge, kettle, toaster, oven, etc.)

• Cleaning and disinfecting countertops, cupboards, and splashbacks

• Scrubbing sinks, taps, and drains

• Cleaning inside cupboards and storage units

• Sanitising dining tables and chairs

• Emptying and disinfecting bins

• Deep cleaning of floors and wall tiles

Premier Contract Cleaning uses food-safe cleaning products to ensure your kitchen remains spotless, hygienic, and compliant with safety standards.

d. Restrooms and Washrooms

Washrooms are critical hygiene zones that demand the highest cleaning standards.

Included in a deep clean:

• Full disinfection of toilets, urinals, and sinks

• Scrubbing tiles, grout, and partitions

• Cleaning mirrors, dispensers, and fixtures

• Sanitising high-touch areas (door handles, flush buttons, taps)

• Descaling taps and fittings

• Refilling soap, tissue, and sanitizer dispensers

• Deodorising and air freshening

Premier Contract Cleaning uses hospital-grade disinfectants and eco-friendly solutions to eliminate bacteria, viruses, and odours — leaving restrooms spotless and safe.

e. Windows and Glass

Clean windows make a huge difference to the appearance and brightness of your workspace.

Deep cleaning covers:

• Interior window cleaning

• Glass partition cleaning

• Window sill and frame wipe-downs

• Removal of smudges, fingerprints, and dust buildup

Premier Contract Cleaning also offers professional exterior window cleaning for multi-story commercial buildings in Dublin — using pure water systems and safety-compliant equipment.

f. Air Vents, Radiators, and Ceilings

Often overlooked, air vents and ceiling fixtures can trap dust and allergens, affecting indoor air quality.

Deep cleaning includes:

• Dusting and vacuuming air vents and radiators

• Wiping ceiling fans and light fittings

• Removing cobwebs from ceilings and corners

Better air circulation means a fresher, healthier workspace — something Dublin’s damp weather makes especially important.

g. Gutter Cleaning (for Commercial Buildings)

If your building has external gutters, a deep clean often extends outdoors too.
Blocked gutters can cause leaks, water damage, and even structural issues.

Premier Contract Cleaning provides safe, professional gutter cleaning using high-reach vacuum systems — ensuring rainwater flows freely and your property stays protected year-round.

h. High-Touch Points and Shared Equipment

Deep cleaning also pays special attention to frequently touched surfaces like:

• Door handles

• Switches

• Railings

• Elevators

• Printers and shared office machines

These areas are disinfected with eco-friendly, fast-drying sanitizers — reducing the spread of germs without leaving chemical residues.

4. The Equipment and Products Used

A key difference between DIY cleaning and professional deep cleaning is the quality of tools and products used.

Premier Contract Cleaning invests in:

• HEPA-filter vacuums for dust-free cleaning

• Steam cleaners for natural disinfection

• Auto scrubbers and floor buffers for hard surfaces

• Eco-friendly cleaning agents (non-toxic, biodegradable, low-VOC)

• Microfibre systems to trap dust and reduce waste

This professional-grade equipment ensures superior results in less time — while maintaining sustainability and safety.

5. Trained and Insured Cleaning Teams

Deep cleaning is detailed, physical work that requires experience and precision.
Premier Contract Cleaning’s team members are:

• Fully trained in professional cleaning techniques

• Vetted, insured, and uniformed

• Skilled in handling delicate materials and finishes

• Trained to follow Irish health & safety regulations

Their structured approach ensures consistency — whether it’s a single office or a large commercial site.

6. When Should You Schedule a Deep Clean?

While daily or weekly cleaning keeps surfaces tidy, a deep clean should be scheduled strategically for maximum benefit.

Common times include:

• Seasonal cleaning (spring and autumn refreshes)

• Before or after events (renovations, moves, or inspections)

• Following illness outbreaks

• Quarterly maintenance for high-traffic offices

Premier Contract Cleaning can help you plan a custom cleaning schedule, ensuring your premises stay consistently fresh without disruption to business hours.

7. How Long Does a Deep Cleaning Take?

The time required depends on:

• Property size

• Number of rooms and restrooms

• Current cleanliness level

• Type of flooring and fixtures

Typically:

• Small offices (under 100 sq. m): 3–5 hours

• Medium offices: 5–8 hours

• Large commercial spaces: 1–2 days

Premier Contract Cleaning offers flexible scheduling, including evenings and weekends, so your workflow remains uninterrupted.

Deep cleaning is an investment in your property’s condition and employee wellbeing.
Costs vary based on size, frequency, and service scope, but Premier Contract Cleaning provides transparent quotes — with no hidden fees.
