Are you a homeowner asking, why is my patio turning green? If so, you’re not alone! Algae, mold, and everyday dirt and grime can leave behind a greenish tinge. Additionally, grass clippings can stain various pavers, as can chemicals and other debris.
While various buildup creates an unsightly look along with patio pavers, this staining isn’t necessarily permanent. Knowing the cause of those stains and how to prevent them can help ensure a stunning patio. Above all, the right cleaning methods can make your patio look new. Keep reading to find out how to maintain your patio’s appearance and lose those unsightly green stains with exterior cleaning services.
Algae and mold are the primary culprits when it comes to a green patio. However, grass clippings and even lawn care chemicals can stain pavers, as said. Additionally, just knowing that mold and algae stain pavers doesn’t help stop this from happening!
In turn, it’s vital that you consider why algae, mold, moss, mildew, and other growth affect your home’s patio. Also, you might consider how to clean that debris properly once your patio begins to discolor. The wrong pressure washing techniques, cleaners, and other details can mean damaging that patio, not cleaning it!
First note what causes green algae, mold, and other growth on pavers. These contaminants thrive in damp conditions. Concrete, pavers, and other outdoor materials are typically very porous. In turn, they absorb moisture that allows mold and algae to flourish.
Additionally, algae and mold grow faster in dark areas without direct light. Therefore, you might notice mold growing behind walls of your home or in bathtubs not exposed to light. In the same way, the darker your property, the more likely you’ll see mold and algae growth!
Grass clippings might also stain patio pavers over time. Think of how often you see grass stains on children’s clothes after they play outside. In the same way, the chemicals in grass can discolor pavers, concrete, and other surfaces.
Also, oily residues such as from automotive fluids might leave behind stains. Some lawn care chemicals might also stain or otherwise damage brick, pavers, and similar materials.
Sunlight, heat, and air circulation hinder mold, moss, mildew, and algae. In turn, you might not notice this same discoloration on patios or walkways exposed to lots of direct sunlight. Removing obstructions such as tree branches over your patio can then help keep moss and other debris away.
However, sun exposure isn’t always the right choice for keeping a patio mold-free. After all, you might appreciate that shade when it’s time to enjoy your outdoor space! Also, homeowners can’t always control sunlight exposure around their property. Cutting back tree branches and other such steps won’t help in areas with heavy cloud cover and rain.
Rather than relying on sunlight and dry weather to keep patio pavers clean, you might consider a few cleaning tips. First, mix a 50:50 white vinegar and water solution and spray this on the pavers. Second, let the solution sit for about 20 minutes. Next, use an outdoor scrub brush and scrub your patio pavers or other surfaces.
Lastly, use a garden hose with a pressure nozzle and wash away all that debris. Repeat this process as needed, until you’ve removed as much green as possible. You can also increase the vinegar part of the solution. Also, wait until the pavers are dry before putting furniture and other items back on the patio.
Copper is an excellent choice for stopping mold, algae, and other growth along a patio. While you can’t just put down a copper layer, you can use copper-based sprays on these areas. Check your local home improvement store for these sprays and use as directed.
If you cannot find these sprays, check for copper sulfate crystals. Stores often sell these in the gardening or even pool and aquarium care sections! Dissolve these in water as directed on the package and apply to when the pavers are bone dry. Let the solution soak into your pavers as a protective layer against mold and other growth.
Professional power washing and paver sealing also helps keep mold and algae growth to a minimum. Washing away mold and algae spores and roots keeps them from growing. Additionally, sealing helps repel moisture. A power washing contractor can note how often your property needs this service!
Also, consider a bagged mower rather than letting grass clippings spray over a patio and other surfaces. You might also rinse off those surfaces after grass cutting. This reduces the risk of residual stains and discoloration.
Vinegar kills mold better than bleach! Bleach kills only surface mold and some spores, while vinegar kills the mold membrane underneath. Also, vinegar is also safer for outdoor lawns and landscaping features.
If a vinegar solution doesn’t kill mold, algae, moss, and other growth on a patio, call in the professionals. Pressure washing contractors often use commercial-grade cleaners meant for pavers and concrete. Additionally, they might also use scrub brushes that help dislodge and clean mold and other debris. In the end, your outdoor space will look like new when you rely on the pros!
Some people might caution homeowners against pressure washing a patio and other outdoor surface. However, when done correctly this service is an excellent investment for any property! Check out some reasons to consider regular power washing around your outdoor space:
Most contractors suggest pressure washing a patio once a year. An annual wash is often enough to remove dirt, grime, dust, mold, and other debris. However, this annual schedule is not a “hard and fast rule.” Consider when you might adjust your schedule for patio and other outdoor power washing.
Property owners should avoid DIY power washing, even if you can rent pressure washing equipment. There are many reasons to leave this work to the professionals! Before you try to tackle patio and other needed washing, consider some reasons to call a contractor instead:
Above all, remember that power washing companies carry insurance against damages. In the rare event of property damage, you can make a claim on their policy. However, should you damage property yourself, repair costs come out of your pocket!
Restoring pavers is typically far cheaper than replacing them. In turn, you might ensure you’ve exhausted every restoration possibility before deciding on new paver installation!
Thorough pressure washing often returns pavers to their original luster. Additionally, wet-look sealants keep that color true for months if not years. Also, remember that you might replace a few broken pavers rather than installing an entirely new patio or walkway.
On the other hand, pavers with a poor base might continue to shift and then crack over time. For this reason, replacing them along with a new base installation might be the better choice. Investing in new pavers also allows you to update their overall appearance! Classic stone, stamped concrete, or bold brick can mean a stunning new look for your property.
Depending on the manufacturing quality, patio pavers should last some 50 to 100 years! However, everyday wear and tear and how you support those materials affect their lifespan. Check out some reasons why your property’s pavers might break down sooner than they should:
Your power washing contractor can also offer advice on how to ensure patio pavers stay in good condition over the years. He or she might also note if it’s time for sealing and other preventative maintenance. In the end, those pavers will stay in good condition for as long as possible!
