Your home is one of your biggest investments — and in a climate like Ottawa’s, it doesn’t take long for dirt, grime, and organic growth to take a toll on your home’s exterior. Whether you’re gearing up for a spring refresh, prepping for the holidays, or just trying to keep your property in top shape, professional house washing is a smart move.
At The Wash Doctor, we specialize in soft washing that’s gentle on siding but tough on stains. Not sure if it’s time for a clean? Here are the top 5 signs your Ottawa home is due for a house washing service.
1. Your Siding Looks Dull, Dirty, or Discolored
Ottawa weather throws everything at your home — rain, snow, wind, and humidity. Over time, this leads to a build-up of dirt, dust, and pollution that sticks to your siding.
Look for:
- Brown or grey discoloration
- A general “dingy” look compared to when it was new
- Uneven patches or streaks
This is especially common on the north-facing sides of homes, where sunlight doesn’t reach as often. A professional soft washing treatment will lift that grime without damaging delicate surfaces like vinyl, aluminum, or wood.
2. You See Green or Black Streaks (Algae, Mold, or Mildew)
If you notice green fuzz or black streaks, particularly near shaded areas or downspouts, it’s likely algae, mold, or mildew. Not only is it unsightly, but it can also degrade siding materials and lead to rot if left untreated.
Ottawa’s fluctuating temperatures and humid summers create ideal conditions for organic growth. At The Wash Doctor, we use biodegradable cleaning solutions that eliminate these organisms at the root — not just wash them away.
Common spots where mold and mildew grow:
- Under eaves and soffits
- Around windows and sills
- Near trees or hedges that block sunlight
3. Your Gutters and Trim Are Stained
Even if your siding looks fine, your gutters, fascia, and trim might tell a different story. Dirty gutters can streak down the siding and leave rust-like stains. White trim can appear yellowed or gray due to pollution and runoff.
A house washing service typically includes gentle rinsing or scrubbing of these areas. At The Wash Doctor, we often pair gutter cleaning with house washing for a complete refresh.
Pro Tip: Consider booking in early spring before heavy rains to prevent further staining from overflow.
4. You’re Planning to Sell or Host Guests
Curb appeal matters — whether you’re listing your home or just welcoming guests. A clean exterior can boost perceived property value and create a great first impression.
Realtors in Ottawa frequently recommend professional pressure washing or soft washing before listing a property. It makes your home photos stand out and signals to buyers that the property has been well maintained.
Situations where house washing makes a big impact:
- Before hosting a backyard event or family BBQ
- Prior to holiday light installation
- When staging your home for open houses
5. It’s Been Over a Year Since Your Last Cleaning
If you can’t remember the last time your home was professionally washed, that’s a sign in itself.
Most Ottawa homes benefit from annual soft washing — usually in the spring or early summer. This helps remove winter grime and sets the stage for a fresh season. Some properties may need more frequent attention depending on their location (heavily wooded lots, high-traffic roads, etc.).
At The Wash Doctor, we can recommend a customized maintenance schedule based on your home’s specific needs — including window cleaning, deck cleaning, interlock cleaning, and more.
Bonus: How House Washing Helps Protect Your Home
Professional house washing isn’t just about looks. It can:
- Extend the life of your siding and paint
- Prevent permanent staining or damage
- Reduce allergens like mold spores
- Prep surfaces for holiday light installation or painting
And with The Wash Doctor’s soft washing process, you don’t have to worry about high-pressure damage. We clean smart, not hard.
Quick FAQ
Q: What’s the difference between soft washing and pressure washing?
A: Soft washing uses low pressure and specialized cleaning solutions to safely clean delicate surfaces like siding. Pressure washing is more forceful and typically used for tougher surfaces like concrete cleaning or interlock cleaning.
Q: How long does a house wash take?
A: Most residential homes in Ottawa can be cleaned in 2–4 hours depending on size and condition.
Q: Will soft washing remove oxidation from siding?
A: Soft washing removes organic growth and surface grime, but not oxidation. We can assess the condition of your siding and let you know your options.
