After a long BC winter, your patio or courtyard often needs a deep refresh. In the Tri-Cities, outdoor living spaces are subject to significant moss growth and 'green slime' algae that make these beautiful areas uninviting and dangerously slippery. Restoring a patio is more than just a quick spray; it's a process of deep cleaning, sanitizing, and preparing the surface for another season of relaxation. This guide covers the essential steps for restoring your patio and courtyard to their former glory, ensuring they are ready for summer entertaining and family enjoyment.

How often should you clean your patio? In Port Moody and Coquitlam, we recommend a thorough clean every 12 to 18 months. Professional restoration costs range from $200 to $450 depending on the surface material and size.
The most important factor is using the correct pressure for your material. Natural stone and stamped concrete can be easily damaged by high pressure. Professionals use rotary surface cleaners and biodegradable surfactants to remove deep-seated organic growth safely, often finishing with a salt-resistant paver sealant to prevent future moss buildup.
Homeowners in Port Moody and Coquitlam value their outdoor spaces, but our local climate works against the longevity of these surfaces.
Moss and Algae Growth: The constant shade from local fir and cedar trees, combined with our humid coastal air, leads to rapid organic proliferation. On patios, this creates a 'biofilm' that is exceptionally slippery when wet, creating a significant liability for guests.
Stain Accumulation: Unlike driveways, patios face unique stains—food grease from BBQs, tannins from fallen leaves, and rust from outdoor furniture. Without professional-grade cleaning agents, these stains can become permanent fixtures in your stone or concrete.
Joint Sand Failure: For paver patios, the 'polysand' between bricks can wash away or become infested with weeds. Professional cleaning focuses on clearing the surface without destabilizing the foundation of your patio.
While patio cleaning seems like a simple task, the variety of modern building materials requires a specialized approach.
Our patio restoration process is meticulous, focusing on both aesthetic results and surface safety.
Site Assessment: We identify the material type and the nature of any stubborn stains to choose the correct cleaning chemistry.
Furniture Management: We carefully stage your outdoor furniture and protect any delicate landscaping around the patio perimeter.
Surface Scrubbing: We use low-pressure rotary cleaners that provide a deep scour without the risk of surface abrasion. This is followed by a thorough rinse with dechlorinated water.
Post-Clean Treatment: We apply a 'top coat' of organic inhibitor that prevents the return of algae for several months, keeping your social space pristine through the peak summer season.
Pricing reflects the complexity of the material and the total square footage of the living space.
Tip: Many homeowners pair this with house washing for a complete 'Summer Ready' package discount. We provide transparent, on-site quotes for every project.
The best time to clean depends on your primary goal: safety or summer aesthetics.
Early Summer (May-June): The most popular time. This clears away the winter buildup just as you are starting to use your outdoor kitchen and BBQ areas.
Post-Leaf Fall (November): Crucial if your patio is in a heavily wooded area like Heritage Mountain. Clearing leaves and tannins before they rot into the stone prevents deep, permanent staining.
Before Major Events: If you are hosting a wedding or a large garden party, a professional clean ensures a safe, non-slip surface for your guests and a beautiful backdrop for photos.
