Skylight cleaning in New Zealand typically costs $150 to $300+, depending on access, roof height, and the number of skylights.
Small, easy-access jobs still usually start from a $150 minimum, while complex or multiple skylights are often priced hourly or after assessment.
Skylight cleaning costs more than standard window cleaning because it involves roof work, safety equipment, and harder access. Most providers will ask for photos or do a site check before giving a final price.
Skylight Cleaning Cost in New Zealand (Pricing Overview)
Skylight cleaning prices in NZ are based on access and risk, not just size. Even a small skylight can cost more than expected if it involves roof work.
That’s why most companies use a mix of minimum charges, per sqm rates, and hourly pricing.
Typical Skylight Cleaning Costs
| Job Type | Pricing Method | Typical NZ Price |
|---|---|---|
| Small skylight, easy access | Per sqm (minimum applies) | $150 + GST |
| Standard skylight job | Hourly rate | $150 – $300 + GST |
| Multiple or complex skylights | Hourly or per sqm + access | $300+ depending on time |
| Minimum visit / small job | Fixed minimum | $150 + GST |
Why Is There a Minimum Charge?
Skylight cleaning requires roof access, safety setup, and trained technicians. Even a quick job involves travel time, risk, and equipment. The minimum charge ensures the job is viable and done safely.
Per sqm vs Hourly Pricing
- Per sqm pricing works for simple, easy-access skylights.
- Hourly pricing is used when roof pitch, height, or access makes time unpredictable.
If a quote seems high for a small skylight, it’s usually because you’re paying for safe roof work, not just glass cleaning.
How Skylight Cleaning Is Priced (How Companies Actually Quote)
Why do skylight cleaners ask for photos first?
Photos show roof pitch, height, and access. These determine safety setup, time on the roof, and risk. Without this, any price is a guess.
When is per sqm pricing used?
Per sqm pricing works for small skylights with easy access. Flat roofs, low pitch, and clear access allow predictable timing. Even then, a minimum charge usually applies.
When does hourly pricing make more sense?
Hourly pricing is used when access is uncertain. Steep roofs, multiple levels, limited ladder placement, or complex skylight shapes make time hard to predict. Hourly rates reflect real labour and safety time.
Why do small jobs still have a minimum charge?
Skylight cleaning is roof work. Setup, safety gear, and travel time are the same whether it’s one skylight or three. The minimum ensures the job is done properly and safely.
What affects the final quote most?
- Number of skylights: More units mean more time.
- Roof pitch and height: Steeper and higher roofs slow the job.
- Access difficulty: Tight spaces or fragile roofing increase setup time.
- Shape and surface area: Larger or curved skylights take longer to clean.
If pricing feels higher than expected, it’s usually because you’re paying for safe access, not just clean glass.
Real Skylight Cleaning Cost Examples
Single small skylight, easy access
One skylight. Low roof. Safe ladder access. Actual cleaning area is small, but roof work is still required.
Per sqm pricing applies, but the minimum charge does the work.
Final cost: $150 + GST.
Medium skylight, hard roof access
One skylight. Higher roof or steeper pitch. Extra time for safety setup and careful movement.
Per sqm rate is calculated, then compared against labour time. Hourly pricing makes more sense here.
Final cost: $150–$250 + GST, depending on access.
Multiple skylights on steep or high roofs
Three skylights. Steep pitch or multi-level roof. Photos show extended setup time and slower movement.
Quoted by time, not size.
Two hours on site at a standard hourly rate.
Final cost: around $300 + GST.
What Affects Skylight Cleaning Cost the Most?
1. Roof height and pitch
Higher or steeper roofs slow everything down. More safety setup. More risk. More time. This is often the biggest cost driver.
2. Ease of access
Clear ladder access keeps costs lower. Tight spaces, fragile roofing, or obstacles increase labour time and price.
3. Number of skylights
More skylights mean more work, but the cost per unit often drops once the crew is already set up on the roof.
4. Size and shape of skylights
Larger skylights take longer to clean. Domed, curved, or custom shapes need extra care and slower cleaning.
5. Condition of the skylight
Heavy dirt, moss, lichen, or oxidation adds time. Neglected skylights always cost more than regularly maintained ones.
What’s Included in Professional Skylight Cleaning?
Exterior glass cleaning
The skylight glass is cleaned to remove dirt, grime, and buildup that blocks natural light.
Frame and surrounding area
Frames and edges are cleaned so runoff does not leave marks after rain.
Surface-safe methods
Pressure is controlled based on roof and skylight type to avoid damage, leaks, or seal failure.
Pure water or soft wash rinse
Mineral-free water is used to reduce spotting and leave a clearer finish.
Final inspection
Skylights are checked before leaving to make sure nothing is missed and no residue remains.
Interior skylight cleaning is usually not included unless specifically requested and quoted.
Skylight Cleaning vs Window Cleaning Cost
Skylight cleaning costs more than standard exterior window cleaning, even when the glass area is similar.
| Factor | Skylight Cleaning | Window Cleaning |
|---|---|---|
| Typical Cost | Higher than window cleaning | Lower, more affordable |
| Access Required | Roof access, often on pitched surfaces | Ground level or basic ladder access |
| Safety Requirements | Harnesses, roof safety gear, extra precautions | Minimal safety setup |
| Setup Time | Longer due to roof access and safety preparation | Short, quick setup |
| Cleaning Speed | Slower, careful movement on the roof | Faster, straightforward |
| Pricing Basis | Based on time, access difficulty, and risk | Based mainly on window size and quantity |
| Glass Size Impact | Small skylights can still take a long time | Larger windows usually cost more |
| Quote Comparison | Should not be compared directly with window pricing | Can be compared with other window quotes |
How Often Should Skylights Be Cleaned?
Most skylights should be cleaned every 12 to 24 months. This keeps light levels high and prevents permanent staining.
Clean more often if:
- Your home is near trees
- You’re in a coastal or high-moisture area
- You notice reduced light indoors
- Moss or grime is visible on the glass
Why waiting costs more
When skylights are left too long, dirt bakes onto the glass. This increases cleaning time and sometimes limits how clear the glass can get again.
Best time to clean
Late spring or early summer works best. Weather is stable, and buildup from winter is easier to remove.
Final Thoughts
Skylight cleaning costs in New Zealand usually start from $150 + GST and increase based on access, roof height, and complexity. Size matters, but access matters more. That’s why photos or an assessment are almost always required before a real quote.
If your skylight is easy to reach and maintained regularly, costs stay predictable. If it’s high, steep, or overdue, expect higher pricing due to safety and labour time.
The key takeaway: skylight cleaning is not a cheap add-on window job. It’s roof work. Budget for safety, not just clean glass.
