How Long Does House Paint Typically Last Indoors and Outdoors?

How Long Does House Paint Typically Last Indoors and Outdoors?

Rodrigo Pereira Teixeira |

A fresh coat of paint can completely transform your home—but how long will that beautiful finish last? Paint longevity depends on several factors, including paint quality, surface preparation, environment, and maintenance. Whether you’re painting an interior living room or the entire exterior of your home, understanding how long paint typically lasts helps you plan for touch-ups and long-term upkeep.

1. How long does interior paint usually last?

High-quality interior paint generally lasts 5 to 10 years before needing a refresh. However, the exact lifespan varies by room and the amount of wear and tear the surfaces experience.

  • Bedrooms and living rooms: 7–10 years

  • Hallways and stairwells: 3–5 years (due to high traffic and scuffing)

  • Kitchens and bathrooms: 3–4 years (humidity and grease can reduce lifespan)

  • Ceilings: 10+ years (less exposure to contact and light)

Randall’s recommends using washable, high-durability interior paints from our Collectionsto extend the lifespan of your walls.

2. How long does exterior paint last?

Exterior paint typically lasts 5 to 10 years depending on weather conditions, paint quality, and surface preparation. In Ottawa’s climate, where we see temperature swings, rain, and snow, premium paints and proper application are essential for longevity.

Here’s a general guide:

  • Wood siding: 3–7 years

  • Aluminum siding: 5–6 years

  • Stucco: 5–10 years

  • Brick (painted): 10–15 years

For optimal results, choose weather-resistant exterior paints that resist UV fading, moisture, and mildew—available at Randall’s.

3. What factors affect how long paint lasts?

Several key factors influence how long paint holds up over time:

  • Surface preparation: Poor prep is the number one reason paint fails early. Cleaning, sanding, and priming properly create a strong foundation.

  • Paint quality: Higher-quality paints contain more pigments and binders, resulting in better coverage, colour retention, and durability.

  • Application method: Applying the correct number of coats with even coverage ensures lasting protection.

  • Environment: Sun exposure, humidity, and temperature changes can cause fading or peeling.

  • Maintenance: Regular cleaning and touch-ups extend the lifespan of any paint job.

Randall’s experts can help you choose the right paint and primer combination for each surface and condition.

4. What are the signs that paint needs to be redone?

Paint rarely fails overnight, but subtle signs indicate it’s time for a refresh. Look for:

  • Fading or dull colour

  • Peeling, cracking, or bubbling

  • Chalking (a powdery residue on the surface)

  • Visible stains or scuff marks

  • Water damage or mold growth

For interiors, fading is often caused by sunlight exposure, while peeling on exteriors is typically a sign of moisture or poor adhesion.

5. How can I make my paint last longer?

Follow these tips to extend the life of both indoor and outdoor paint:

  • Use high-quality products: Premium paints and primers from Randall’s Paint Collectionsare formulated for long-lasting performance.

  • Prep thoroughly: Clean, sand, and prime before painting.

  • Avoid harsh weather: For exteriors, paint during mild temperatures between 10°C and 25°C with low humidity.

  • Clean surfaces regularly: Wipe down walls gently to remove dust, dirt, and oils.

  • Repair damage quickly: Address cracks or peeling early to prevent larger issues.

Proper care not only protects your home but also keeps your paint looking fresh year-round.

6. Do different paint finishes last longer than others?

Yes. The finish you choose impacts durability:

  • Matte and eggshell: Offer a soft look but are less resistant to frequent cleaning.

  • Satin and semi-gloss: More durable and moisture-resistant, ideal for high-traffic or humid spaces.

  • High-gloss: Longest-lasting and easiest to clean but highlights imperfections.

For exteriors, low-sheen or satin finishes perform well because they shed moisture and resist dirt buildup better than flatter finishes.

7. How often should I repaint my home?

  • Interiors: Every 5 to 7 years, depending on room use.

  • Exteriors: Every 5 to 10 years, depending on exposure and paint type.

If you use top-quality paint, prepare surfaces correctly, and perform occasional touch-ups, you may be able to double these timelines.

8. Should I hire a professional painter for longer-lasting results?

While DIY painting is possible, a professional painter ensures consistent application, proper surface preparation, and long-term durability. Professionals understand how to handle different materials and environmental conditions, which can significantly increase the lifespan of your paint.
