Change or Repainting and Which is better Option?

Many homeowner is wondering when come to decision to change a new windows or to repainting with new coating. Let’s explore and consider the criteria when you decision the option for repainting it:

• Ages of windows : The condition of windows frame and ages of windows are main concern. If the windows frame are too bad in condition, ironmongeries area required to be replaced, frame are damaged or dented, the repair cost + repainting cost become excessive and not economical.
• Renovation or Occupies : The timing is another important consideration. The idea situation either to choose replacement or repainting is when your unit is under renovation. Either option will generate dust, noisy and site constraint are the keys. The best timing of repainting of your windows or doors are before you complete the painting of wall/ ceiling, flooring and carpentry. This is because the repainting process will generate a lot of flying particulars and need a lot of protection and might stain the existing completed items ( eg. fittings, windows film, carpentry, furniture etc.) which is not easy to be removed.
• Full height windows or curtain windows : The cost of replacement of new windows will be costly and hassle to replace it as it will require to have PE design/ submission, engage licensed builder and windows contractor and longer time needed and higher cost needed when compare with repainting it.
• Dislike the colour of Aluminum Window and Door : The existing design is not matching the themes of renovation design, and existing frames are new and in good condition. Repainting it will be cheaper option if compare to replacement, however, the repainting work is only available to apply to internal side of frames, exclude intermediate frame and external side due to site constraint.
• Damages and Wear and Tear : If existing windows are damages ( eg. ironmongeries faulty, leaking issues, damages and beyond touch up etc), repainting it will not solve or improve the situation of existing windows. You may best to consider to replace it and repair it if it is minor. You may consider to replace all the movable panels and repainting the fixed framing if it is not easy to replace. The combines option is the alternative solution.
• Quality of Finishing Expectation : The method of on-site spray repainting is using Epoxy or PU Paint like similar to body car repainting process. However, the quality of finishing and durability is not able to compete with powder coating in factory ( closed and control painting method and oven curing process). If you are looking for perfect finishing, you are advise to replace a new set instead of repainting it. The on-site painting method have many site constraint, protection constraint, uniformity of paint mixing and subject to site spraying skills will be varies and commonly have some limitation of the colour tonality and edge perfectionist limitation issue. If you are very fussy of the details of painting quality, don’t choose repainting.
• Long Lasting of Paint : Spray painting is not as last compare with powder coating painting in factory. However, the spray painting using Epoxy or PU paint which is as good as car body painting, where it will be a better option compare using normal fast dry paint or enamel paint. The spray paint with PU paint is easily last more than 5 years exclude damages or discoloring. The repainting is ideas when the condition of existing aluminum frame is in good condition and in full height/ big framing when compare to replace it.
• I am staying and occupies : If you are looking to improve the look of aluminum window or door frames but you am staying in yet look to repaint it windows/ doors. This might not suits you when :
  • Can’t tolerate and allergic with paint
  • House is full of stuffs, not able to relocate, shifting of obstruction to windows
  • The windows glass are coated with solar shield or solar films. As the protection may not be 100% and might be stained, unless you are plan to replace a new films
  • Carpet flooring, expensive stuffs that may in risk when stain with paint. We are only offer limited protection and not able to provide ” full proof” of protection during spray painting process. We will not liable for any damages and risk to stained your existing properties.
  • Cleaning of paint droplets and damaged of wall or ceiling painting is required by the owner. If you are not able to arrange for extra cost for cleaning and repainting of wall and ceiling, you may need to consider to replace the whole windows frame instead of spray paint the windows.
  • The spray painting work may take up for a few days and inconvenience during the work process. If you are difficulty to arrange for “staycation” somewhere for the renovation, this might not be an option.
  • Do take note the touch up work for existing wall or ceiling or flooring painting may be stained by spray painting work. Additional cost to be imposed or owner to arrange their own painter.
• Existing Windows Grilles and Invisible Grilles : The existing of windows grilles or invisible grilles are required to be removed prior for spray painting work to the windows frame or fix panel. This is because, the obstruction of the grilles may cover part of the windows and may affect the painting. The grilles or invisible grilles can not the fully protected when painting and need separate arrange to dismantle and reinstallation. As for old aluminum grilles are basically is in round edges, spray painting is not suitable to do it on site and better in factory can have hang and spray paint or sides at one time.
