The Ultimate House Washing FAQ: Everything You Need to Know

Professional house washing

We all agree that there is no place like home. This saying resonates deeply with maintaining a clean and tidy living environment. New Zealanders often take pride in their homes, viewing them as reflections of themselves and their families.

A clean home is seen as inviting, welcoming, and helpful to relaxation and happiness. Nurturing our living spaces requires nurturing not only inside our houses but also their external appearance. Therefore, house washing plays a big role in providing this vision.

Imagine a caring homeowner in a cosy suburban neighbourhood who is deeply invested in maintaining the beauty of their home’s exterior surfaces. Over time, nature’s elements take their toll, leaving the exterior dull and stained.

However, with a thoughtful decision by the homeowner to enlist a professional house-washing service, the home will undergo a transformative renewal. The dirt and mould are softly eliminated, and the siding will shine, adding an attractive vibe to the neighbourhood.

If you’re looking at professional washing of your house but don’t know where to start, this article will cover all the essential details about house washing. 

What is house washing, and why is it important?

House washing refers to the process of cleaning the exterior surfaces of a house to remove dirt, grime, mould, mildew, algae, and other contaminants. It typically involves using water, detergents, and sometimes specialised cleaning equipment such as pressure washers or soft wash systems.

Therefore, it’s important for several reasons;

Preservation of Structural Integrity: 

House washing helps maintain a home’s structural integrity by removing dirt, grime, mould, mildew, algae, and other pollutants that accumulate on exterior surfaces over time. This prevents the buildup of contaminants and extends the lifespan of siding, roofing, and other exterior materials while reducing the risk of deterioration and damage.

Enhanced Curb Appeal: 

Regular house washing improves a home’s aesthetic appearance while enhancing its curb appeal. By removing stains, discolouration, and organic growth from exterior surfaces, house washing makes a home look cleaner, fresher, and more inviting. This is particularly important for homeowners looking to sell their property or maintain its value over time.

Healthier Indoor Environment: 

House washing also eliminates mould, mildew, and other allergens from exterior surfaces, improving indoor air quality. By reducing the presence of allergens, house washing can help ease respiratory issues and allergies for occupants, creating a healthier living environment.

Prevention of Damage:

Accumulated dirt, grime, and organic growth can cause damage to exterior surfaces over time if left unchecked. House washing prevents this damage by removing contaminants before they have a chance to cause deterioration or staining. By investing in regular house washing, homeowners can avoid costly repairs and replacements.

Protection of Investment: 

A home is one of the largest investments most people will make in their lifetime. Making house washing an important part of protecting this investment by maintaining the exterior surfaces of the home in good condition.

By keeping the exterior clean and well-maintained, homeowners can preserve the value of their property and ensure its long-term durability.

Prevention of Pest Infestations: 

Dirt, grime, and organic matter on exterior surfaces can attract pests such as insects, spiders, and rodents. House washing removes these visitors, reducing the likelihood of pest infestations around the home. By keeping the exterior clean and debris-free, homeowners can minimise the risk of unwanted pests entering their property.

How often should I wash my house?

Cleaning a surface with pressure washer

Generally, it’s recommended to wash your house every 12 to 24 months to maintain its cleanliness and structural integrity. 

However, certain factors might necessitate more frequent washing. For instance, homes located in coastal areas or regions with high humidity may require more frequent cleaning due to increased exposure to salt, moisture, and airborne pollutants. 

Similarly, houses surrounded by trees or in areas prone to heavy rainfall may accumulate dirt and organic matter more quickly, requiring more regular washing. 

What are the benefits of professional house washing versus DIY methods?

Professional house washing services offer several advantages over DIY methods. These services provide superior results using commercial-grade equipment and specialized cleaning agents.

The trained technicians have extensive experience. They use these tools to remove dirt, mould, and mildew from various exterior surfaces.

Hiring professionals saves homeowners time and effort. They handle all aspects of the cleaning process while ensuring safety and environmental responsibility. 

Furthermore, professionals can protect delicate surfaces and minimize the risk of damage, providing homeowners with peace of mind.

Is soft washing better than pressure washing?

Soft washing is often considered superior to pressure washing for certain surfaces and situations due to its gentler approach and effectiveness in removing contaminants without causing damage. 

Unlike pressure washing, which employs high-pressure water spray, soft washing utilises lower water pressure and specialised cleaning solutions to gently clean delicate surfaces such as painted wood, siding, and roofing materials. 

This gentler method reduces the risk of surface damage and water intrusion into cracks or gaps, making it safer for the integrity of the structure.

Moreover, soft washing uses biodegradable cleaning solutions, which are environmentally friendly. Its longer-lasting results help inhibit the regrowth of mould, mildew, and algae. 

Soft washing is preferred for maintaining sensitive exterior surfaces. It ensures thorough cleaning with minimal risk. On the other hand, pressure washing is suitable for tougher surfaces or heavily soiled areas.

Is house washing safe for both pets and plants?

“Pet and plant-friendly house washing” is a cleaning technique that ensures the safety of pets and plants within and around the household. Here are some key points to note about this approach:

Non-toxic Cleaning Agents: 

Eco-friendly and biodegradable cleaning solutions are used, which do not contain harsh chemicals or ingredients that could be harmful to pets if ingested or come into contact with their skin.

Safe Application:

The cleaning agents are applied in a manner that minimises exposure to pets and plants.

Technicians will take extra care to avoid spraying directly onto areas where pets frequent or onto vegetation, or they may take measures to protect these areas during the cleaning process.

Rinsing and Dilution: 

After application, the cleaning agents are thoroughly rinsed to remove any residue, ensuring that surfaces are left clean and free of potentially harmful substances.

Cleaning solutions may also be diluted to further reduce their concentration and minimise environmental impact.

Consideration of Surroundings: 

When washing a house, we consider where pets and plants are located to ensure they’re not harmed by the cleaning process. We take precautions to keep them safe from any negative effects.

This may include temporarily relocating pets or covering plants during the cleaning process.

How long does a typical house washing service take?

On average, a standard house washing service may take a few hours to a full day to complete. For a more accurate estimate, consult with a house-washing expert in Hamilton.

Are there any health risks associated with house washing?

When considering the health risks associated with house washing, it’s essential to recognise that careful handling of cleaning solutions or exposure to contaminants can pose risks to both homeowners and professional cleaners.

However, when working with an expert, the health risks are generally minimal, as professionals are trained to prioritise safety and follow industry standards. 

They typically use protective gear such as gloves, goggles, and masks to minimise exposure to cleaning solutions and airborne particles.

Additionally, reputable cleaning companies ensure that their staff are adequately trained in handling chemicals and that they are following safety protocols to mitigate any potential health hazards.

By entrusting the job to experienced professionals, homeowners can minimise health risks while still enjoying the benefits of a clean and well-maintained exterior.
