Exterior paint is the first line of defense for wood siding and trim. A good low-VOC paint protects the house with fewer fumes, and the right prep makes it last years longer.
What to look for
- Low or zero VOC on the label
- 100% acrylic formulas for flexibility and adhesion
- Mildew resistance for shaded, damp walls
- A primer matched to the surface: bare wood, fiber cement or previously painted
Prep matters more than the paint
- Repair rot and replace soft wood first
- Wash the surface and let it dry fully
- Scrape loose paint and sand edges
- Prime bare wood and all cut ends
- Caulk joints with a paintable exterior sealant
Best time to paint here
Dry weather with mild temperatures, typically late spring to early fall. Avoid painting right before rain or on surfaces that are still damp from the morning.
How long exterior paint lasts
| Surface | Typical repaint cycle |
|---|---|
| Fiber cement | About 10–15 years |
| Engineered wood | About 10 years |
| Cedar and wood trim | About 5–8 years |
| South and west walls | Often sooner |
Repair before you repaint
Painting over rot is the most common mistake we see. We repair the wood and flashing first, then leave surfaces primed and ready for your painter, or paint them ourselves.
Frequently asked questions
Is low-VOC paint as durable?
Quality low-VOC acrylics perform as well as traditional paints for most exterior uses.
Should trim be painted with the same paint?
Often a higher-sheen version of the same line is used for trim because it cleans easier and sheds water.
Do you paint after repairs?
Yes. We can prime only, or paint repaired areas to match.
