Restoring the Beauty of a Brick Home: Pressure Washing and Roof Mold Removal in Chestnut Hill, MA

Oct 20, 2025

At HiCleaners, we take pride in transforming homes across Massachusetts by restoring their exterior beauty, protecting surfaces from long-term damage, and ensuring every homeowner can feel proud of their property. Recently, our team had the pleasure of completing a detailed pressure washing and roof mold removal project for Deborah S. in Chestnut Hill, MA.

This project was a perfect example of how proper maintenance and professional cleaning can completely revitalize a home’s appearance and health. Deborah’s brick house had accumulated years of organic buildup, including dark mold stains on the roof and algae growth along the siding and walkway. After our comprehensive cleaning service, her home looked refreshed, vibrant, and better protected for the upcoming seasons.

To show our appreciation for her trust in HiCleaners, we also soft washed her deck and railings as a complimentary service, leaving the entire property spotless.

1. Understanding the Problem: Mold, Algae, and Dirt on Brick and Roof Surfaces

Chestnut Hill’s beautiful tree-lined streets and humid microclimate create the perfect environment for mold, mildew, and algae growth—especially on brick homes and asphalt shingles. Deborah had noticed her roof was developing dark streaks and patches, which are often mistaken for dirt but are actually caused by Gloeocapsa magma, a type of algae that feeds on the limestone filler in shingles.

This type of growth doesn’t just look bad—it shortens the lifespan of a roof by trapping moisture and promoting decay. On brick surfaces, green or black mold can also cause discoloration and slowly weaken mortar joints over time.

When Deborah reached out to HiCleaners, she explained that her home was starting to lose its original charm, and she wanted a safe, effective, and long-lasting solution—without risking damage to her brick or roof materials.

2. Step One: Professional Pressure Washing of Brick Walls and Walkways

Pressure washing brick requires the right balance between cleaning power and surface protection. Too much pressure can etch the surface or loosen mortar joints, while too little may not remove deep-seated dirt or mold.

Our HiCleaners team began by inspecting all exterior brick areas, including the front façade, walkways, and retaining walls. We noticed areas where moss and grime had collected in shaded spots, and we chose the proper nozzles and cleaning agents for each surface.

Our process included:

Pre-treatment: Applying a biodegradable detergent to loosen mold and dirt.
Low-to-medium pressure rinse: Carefully cleaning the brick without damaging mortar.
Detail work: Removing any remaining spots from edges and corners with specialized attachments.

After just a few hours, Deborah’s brick siding returned to its natural red and brown tones. The transformation was dramatic—what once looked dull and weathered now appeared freshly built.

She mentioned she couldn’t believe her brick could look that clean again without repainting or replacing anything.

3. Step Two: Roof Mold Removal Using HiCleaners’ Soft Washing System

The next major part of the project involved roof cleaning and mold removal. Unlike pressure washing, roof cleaning requires a much gentler approach to avoid damaging shingles. HiCleaners used our soft washing system, which relies on low pressure and eco-friendly cleaning solutions designed to kill and remove organic growth safely.

The soft washing process:

1. Inspection and protection: We first checked the roof’s condition, gutters, and flashing, then covered nearby plants and shrubs to protect them from cleaning runoff.
2. Application of cleaning solution: Our technicians evenly sprayed a biodegradable solution formulated to eliminate algae, moss, and lichen at their root.
3. Dwell time: The solution was left to work for 15–20 minutes, allowing it to break down the growth.
4. Gentle rinse: We then rinsed the roof with low pressure to remove dead organic material and restore the roof’s original color.

The result was immediate. The dark streaks disappeared, the shingles looked renewed, and the entire roofline appeared lighter and cleaner.

Deborah was amazed at how much newer her roof looked. She mentioned it was like “a facelift for the whole house.”

4. Protecting Surrounding Landscaping and Surfaces During the Cleaning Process

At HiCleaners, we know that every home is unique—and so is every landscape. Chestnut Hill homes often feature mature trees, decorative shrubs, and gardens that need special attention during exterior cleaning.

Before starting any washing work, our team carefully covered sensitive areas such as flower beds and hedges. We also used water neutralization techniques to prevent any chemical residue from affecting the soil or plants.

All cleaning solutions we use are biodegradable and environmentally safe, designed to break down naturally after neutralization. Our technicians also performed a full rinse of all ground surfaces to ensure no overspray or runoff remained after cleaning.

By maintaining strict environmental standards, HiCleaners ensures that every cleaning job enhances both the appearance and health of the property.

5. Complimentary Deck and Railing Soft Wash for Deborah S.

As a thank-you to Deborah for choosing HiCleaners, our team provided a complimentary soft wash for her deck and railings after completing the main project.

Her wooden deck had collected a thin layer of mildew and grime, which made the surface slippery and dull. Using our soft wash technique, we applied a gentle cleaner that lifted dirt and organic buildup without damaging the wood fibers or paint.

The results:

The deck regained its natural color and brightness.
The railings looked freshly painted.
The surface was safer to walk on, especially after rain.

Deborah was thrilled and said she didn’t expect her deck to look “this good without sanding or staining.” She even mentioned that she planned to host a small family gathering that weekend to show off her newly refreshed outdoor space.

This small gesture reinforced what HiCleaners stands for - overdelivering value, earning trust, and building long-term relationships with clients.

6. Why Professional Pressure Washing and Roof Cleaning Matter for Home Longevity

Many homeowners underestimate the impact that dirt, mold, and algae can have on their property’s long-term condition. In reality, regular exterior cleaning is one of the most cost-effective maintenance steps a homeowner can take.

Key benefits of professional cleaning:

Prevents structural damage: Mold and algae trap moisture, leading to cracks, rot, and decay.
Enhances curb appeal: A clean home exterior immediately looks newer and better maintained.
Increases property value: Well-maintained surfaces can add thousands to resale value.
Improves health and safety: Mold spores and slippery surfaces can create health and fall hazards.
Extends lifespan of materials: Removing harmful growths preserves brick, shingles, and decking for years longer.

In Deborah’s case, her roof had at least five to seven years of life left—but if she hadn’t acted, mold growth could have shortened that by half. After our service, she was confident she had made the right investment for both appearance and protection.
