Exterior house washing in Melrose, MA

The most common solution for exterior house washing is sodium hypochlorite (SH), mixed with water and a surfactant.
Sodium hypochlorite helps remove green algae, mold, mildew, and other organic stains.
Professional house washing often uses a final SH concentration of 0.5%–1.5%, depending on the siding and contamination.
A surfactant helps the solution cling to siding and improves cleaning performance.
For vinyl siding with light algae, a 0.5%–1% SH solution is often a good starting point.
For heavier organic growth, a stronger concentration may be necessary if the surface and product label allow it.
Apply the solution using a low-pressure soft-washing method rather than high-pressure blasting.
Pre-wet plants and thoroughly rinse landscaping before, during, and after washing to minimize chemical damage.
Protect sensitive metals, painted surfaces, and other materials, and never let the solution dry on them.
Never mix sodium hypochlorite with acids or ammonia, and always follow the chemical manufacturer’s safety instructions.

Roof soft washing in Hampstead, NH

Roof moss grows mostly on the north-facing side of your roof, especially in Massachusetts, where that area receives less direct sunlight and stays damp longer.

The areas most likely to develop roof moss are:
North-facing roof slopes — receive less sunlight and dry more slowly.
Under tree shade — branches block sunlight and keep the roof damp.
Roof valleys — can collect moisture, leaves, and other debris.
Along shingle edges and overlaps — moisture can linger between shingle layers.
Near chimneys and dormers — these areas can create shaded spots.
Low-sunlight areas near the ridge — depending on roof orientation and surrounding trees.

Exterior house washing in Foxborough, MA

You should always close all windows and doors before pressure washing your house. Even a small gap can allow water to enter and cause damage.
Here are 5 important tips:
Close all windows tightly to prevent water from entering your home and damaging window frames, walls, or interior finishes.
Check window seals. Older or damaged seals may allow water inside, even when windows are closed.
Avoid spraying directly into window edges. High-pressure water can damage caulking, weatherstripping, and seals.
Use soft washing for siding when appropriate. Lower pressure is generally safer for vinyl siding, painted surfaces, and exterior trim.
Close exterior doors and protect electrical outlets. Cover vulnerable electrical fixtures and ensure they are suitable for wet conditions.

Exterior window cleaning in Salisbury, MA

Here are 5 important things to know:
Pure water is generally safe. Water-fed pole systems use purified water to remove dirt and leave glass spot-free without chemical detergents.
Exterior window film: Most exterior-rated films can be cleaned with purified water and a soft brush, following the film manufacturer’s instructions.
Interior window film: If your film is installed on the inside of the glass, exterior water-fed cleaning is generally safe, provided the windows are properly sealed and there are no leaks.
Brush selection matters. Use a soft, non-abrasive brush. Stiff bristles or excessive pressure can scratch or damage certain film surfaces.
Special coatings require care. Reflective, tinted, low-E, and specialty films may have specific cleaning requirements. Avoid aggressive scrubbing and high-pressure spraying around window seals.

Exterior house washing in Manchester, MA

Soft washing is better for delicate surfaces, while pressure washing is ideal for durable surfaces.
Soft washing uses low-pressure water and specialized cleaning solutions to remove algae, mold, and mildew.
Pressure washing uses high-pressure water to remove stubborn dirt, grime, and surface buildup.
Soft washing is the preferred method for cleaning roof shingles because it helps prevent damage.
It is also effective for vinyl siding, painted surfaces, stucco, and other delicate materials.
Pressure washing works best on concrete driveways, sidewalks, patios, and other durable surfaces.
Soft washing kills organic growth, helping prevent algae and mold from returning quickly.
Pressure washing can remove visible algae but may leave some living organisms behind.
Using excessive pressure can damage siding, strip paint, loosen shingles, or harm concrete.
For the best results, choose the cleaning method based on the surface material and the type of contamination.

Pressure washing in Framingham, MA

To prevent green algae from coming back after pressure washing, you need to treat the algae and reduce the moisture and shade that encourage regrowth.
7 ways to prevent green algae from returning
Use an appropriate cleaning solution. Apply a suitable algae treatment before or during cleaning to help kill the growth, rather than relying on pressure alone.
Consider soft washing. For house siding and other delicate surfaces, low-pressure cleaning with an appropriate treatment can remove algae without damaging the material.
Trim overhanging trees. More sunlight and airflow help surfaces dry faster.
Improve drainage. Fix leaking gutters, overflowing downspouts, and areas where water collects.
Clean regularly. Inspect shaded siding, patios, walkways, and retaining walls at least once or twice a year.
Remove organic debris. Sweep away leaves, dirt, and pollen that retain moisture and support algae growth.
Use surface-appropriate preventative treatments. Some surfaces can benefit from periodic treatments designed to slow algae regrowth. Follow product directions and protect plants and nearby waterways.

Roof soft washing in Randolph, MA

Roof moss and roof algae are two common problems that affect the appearance and condition of your roof. Roof moss is a green, thick, plant-like growth that usually develops in damp, shaded areas. Roof algae typically appears as black streaks or dark stains on asphalt shingles. The most common type of roof algae is called Gloeocapsa magma. Moss holds moisture against the roof and can lift shingles, potentially causing damage over time. Algae mainly affects the roof’s appearance, although it can spread across large areas. Both problems thrive in environments with moisture and limited sunlight. Moss is usually easier to identify because it grows above the shingle surface. Algae typically spreads across the shingles as dark discoloration. Professional roof cleaning can help remove both moss and algae when the appropriate treatment is used. Soft washing is generally recommended for asphalt shingles because high-pressure washing can damage them. Regular roof inspections and proper maintenance can help keep your roof clean and extend its lifespan.

Exterior house washing in Arlington, MA

You can wash your house in cold weather, but the temperature must be suitable for safe and effective cleaning. For homeowners in Massachusetts, professional exterior house washing can sometimes be done during the fall and mild winter days.
Ideal temperature: Above 40°F is generally preferable for exterior house washing, although the appropriate temperature depends on the cleaning solution, siding material, and equipment.
Avoid freezing temperatures: Water can freeze on siding, walkways, and roofs, creating dangerous conditions and potential damage.
Choose the right cleaning method: Soft washing is often preferred for vinyl siding because it uses low pressure and a suitable cleaning solution.
Check the forecast: Make sure temperatures will remain above freezing long enough for surfaces to drain and dry safely.
Protect plants: Cold-weather cleaning still requires proper rinsing and care around landscaping.
Watch for ice: Avoid washing when water could freeze on driveways, decks, stairs, or walkways.
Consider the wind: Strong winds and cold conditions can make cleaning less effective and less comfortable.
