Thinking of changing your old aluminium window frames from brown to black, white or grey?
Before you confirm a window spray painting quotation in Singapore, check what the price actually covers. Two quotations for the same home may include different preparation, painted surfaces, protection and touch-up work.
A clear quotation should identify which window surfaces will be painted, how they will be prepared, the coating system, protection arrangements and any additional charges. It should also explain what repainting will not fix.
1. Which Window Surfaces Will Be Painted?
A standard 9RENO quotation for internal window spray painting covers the frame surfaces visible from inside the home when the window is closed.
It excludes:
- Intermediate sections exposed when the window is opened.
- External-facing surfaces.
Opening a window may reveal sections that retain their original colour. This is outside the standard internal spray painting scope.
Before confirming, identify the window sets and balcony door frames included. Any additional surfaces should be assessed and quoted separately.
2. What Surface Preparation Is Included?
A new coat needs a suitable surface underneath it. Applying paint over dirt, loose coating or an unsuitable previous finish can affect adhesion.
Depending on the existing condition, preparation may include:
- Cleaning and degreasing.
- Removing loose or peeling paint.
- Sanding or abrading the existing finish.
- Preparing oxidised or damaged areas.
- Repairing agreed minor surface defects.
- Applying a compatible primer where required by the coating system.
Not every window needs complete paint stripping. However, a frame that has already been brush-painted or poorly repainted may need more preparation than an intact factory-coated frame.
Ask: “Does this quotation include preparing the existing coating, and what happens if more loose paint is found?”
3. Are Scratches, Holes and Window Repairs Included?
Repainting improves the surface appearance. Mechanical repairs and leakage repairs are separate work unless specifically included.
Check whether the quotation covers any agreed:
- Filling of old screw holes.
- Treatment of surface scratches.
- Repairs following grille removal.
- Replacement of worn rubber gaskets.
- Roller, hinge, handle or lock repairs.
- Investigation and repair of water leakage.
A window can look freshly painted and still have a faulty roller or leaking joint. Tell the contractor about these problems before confirming the scope. Ask for repairs to be listed separately so you can see what you are paying for.
4. What Paint System and Finish Will Be Used?
Ask the contractor to state the proposed coating system and finish. Useful details include:
- Paint type and product information.
- Primer requirements.
- Application method.
- Selected colour or colour reference.
- Matt, satin or gloss finish.
- Limitations when matching an existing colour.
At 9RENO, PU paint is commonly used for aluminium window frame spray painting. The preparation and coating specification should suit the existing surface and agreed scope.
If you want to match an existing frame, provide its colour code where available. A colour viewed on a phone screen may look different from the actual painted finish.
5. What Protection and Masking Are Included?
A standard 9RENO window spray painting quotation is based on a unit under renovation.
If carpentry has already been installed or wall painting has been completed, additional protection is required and will be quoted separately following an assessment.
Tell us before quotation if the unit has:
- Completed carpentry or built-in cabinets.
- Freshly painted walls and ceilings.
- Finished flooring.
- Furniture, curtains or personal belongings.
- Existing solar film.
Protection and masking help reduce overspray, but they do not guarantee that surrounding finishes will remain unaffected.
Where possible, schedule window spray painting before final wall painting and carpentry installation.
6. What Happens to Solar Film, Gaskets and Grilles?
These items can affect access to the frame and the sequence of work. Before confirming, discuss:
- Whether existing solar film will remain or be replaced.
- The condition of the rubber gaskets.
- Whether grilles obstruct the surfaces to be painted.
- Whether dismantling and reinstatement are necessary.
- Who will arrange specialist removal or reinstallation.
Do not assume grille removal, gasket replacement or solar film replacement is included in the painting price.
Read our guide to window spray painting and solar film for related planning considerations.
7. Are Wall Touch-Ups and Repainting Included?
A standard window spray painting quotation does not include wall touch-ups or wall repainting.
Paint overspray may affect adjoining painted surfaces. Removing masking tape may also lift or damage existing wall paint.
Plan for wall touch-ups or repainting after window spray painting. These works should be arranged with your renovation painter or quoted separately if requested from 9RENO.
If your walls have already been painted, allow for both additional protection charges and subsequent wall painting work.
8. What Is the Work Schedule?
Ask for the expected work duration and any period needed before normal cleaning or use.
The schedule can depend on the number of windows, existing coating, repairs, access, site conditions and the paint system.
For an occupied home, clarify:
- Which rooms need to be cleared.
- Whether occupants need alternative arrangements during the work.
- Ventilation requirements.
- When windows can be operated.
- When the frames can be cleaned.
- Whether other renovation trades can work nearby.
“Painting completed” and “coating fully cured” are not necessarily the same point. Follow the instructions provided for the actual coating used.
9. What Could Change the Final Price?
A useful quotation explains both its assumptions and the circumstances that could require additional work. Clarify:
- Extra preparation for a failed previous coating.
- Additional window sets or surfaces outside the standard internal scope.
- Changes to the selected colour or finish.
- Special access equipment.
- Additional protection after carpentry or painting is completed.
- Grille dismantling and reinstatement.
- Gasket or hardware replacement.
- Wall touch-ups and repainting, which are excluded from the standard quotation.
- Building access arrangements and applicable charges.
- Whether GST applies and is included.
Any additional work should be explained and agreed before it proceeds.

Frequently Asked Questions
Can I get a window spray painting quotation from photos?
Photos can help with an initial assessment. Send an overall view of each window set, close-ups of defects, approximate dimensions and your preferred colour. A site assessment may still be needed to confirm preparation, access and protection requirements.
Does internal window spray painting include the middle sections and outside?
No. The standard scope covers frame surfaces visible from inside when the window is closed. Intermediate sections and external-facing surfaces are excluded.
Why is one window painting quotation higher than another?
The quotations may cover different surfaces, preparation, repairs, protection or access arrangements. Compare the written scope before comparing the total price.
Does window frame repainting stop water leaks?
Repainting should not be treated as a substitute for diagnosing a leak. Water may enter through joints, seals or other defects that require separate repair.
Can I spray paint windows after moving in?
It may be possible following an assessment. A standard quotation assumes a unit under renovation. Completed carpentry, wall painting, furniture and other finishes may require additional protection and charges. Discuss clearance and occupancy arrangements before booking.
Will I need to repaint the walls afterwards?
Plan for wall touch-ups or repainting after window spray painting because overspray and masking tape removal can affect existing wall paint. Wall painting is not included in the standard window spray painting quotation.
Should I choose the lowest quotation?
Choose a quotation with a clear scope, suitable preparation and realistic expectations. A lower price may be appropriate for a simpler job, but check that necessary work has not been left out.
