Frequently Asked Questions

If you have any questions about our services, please refer to the FAQ below, or feel free to contact us.
We will respond to all inquiries as promptly as possible.

Is it possible to carry out painting maintenance during the rainy season?
Yes, we provide painting services throughout the year.
About how long does the painting work take?
The duration depends on the scale of the project. As a guide, an area of approximately 3,000 m² takes around 2 weeks. If there are rainy days, the schedule will be extended by the number of days work could not be carried out.
Can Astec handle work other than painting?
We handle roof replacement and can also replace rain gutters, skylights, ventilation, and other metal components. We can also propose safety measures for working at height for your review.
How often should repainting maintenance be done?
Generally, repainting is recommended every 10 years.
Can Astec do spot painting to seal a specific leak?
Yes. We would need to conduct an on-site inspection to identify where the rainwater is entering and pinpoint the source of the leak.
What is the best season for painting?
Painting is generally carried out during the dry season (November to April). Painting during the rainy season has the advantage of being able to check for leaks at the same time as the work is carried out.
How is the surface prepared before painting?
We use a high-pressure washer dedicated to painting work, which is used for cleaning, in addition, we also carry out surface sanding, crack repair, surface preparation, and rust prevention treatment, among other steps.
If the roof leaks, does the whole roof need to be replaced?
Not necessarily. We will thoroughly investigate the cause of the leak. If it turns out to be localized, we can repair just that area without replacing the entire roof, which can significantly reduce costs.

How do you ensure safety when working at height?
