Over time, concrete surfaces like patios, walkways, and steps can become covered in a dark layer of dirt, algae, and mildew. In Connecticut’s climate, this buildup is not just an eyesore that diminishes your home’s curb appeal; it also creates dangerously slippery surfaces when wet. These organic growths and stains penetrate deep into the concrete’s pores, making them impossible to remove with a simple garden hose.
Many homeowners turn to rented pressure washers, only to find the results are temporary and inconsistent. Without the right technique and cleaning solutions, DIY methods often create more problems, from “zebra stripes” and surface spalling to failing to kill the algae at its root, leading to its rapid return. This approach merely scratches the surface, leaving deep-set contaminants and organic spores behind.

For durable, flat surfaces like most concrete, pressure washing with a surface cleaner is the most effective method. It uses higher pressure to deep-clean the pores. Soft washing, which uses low pressure and more chemicals, is reserved for more delicate surfaces. Our technicians always assess the surface to choose the safest and most effective method.
The discoloration you see is living organic matter. Green is typically algae, and the black streaks are often a hardy type of algae called Gloeocapsa magma. They thrive in Connecticut’s humid weather, feeding on the minerals in your concrete. Our process kills these organisms; it doesn’t just rinse them away.
Yes. Protecting your property is our top priority. We pre-saturate surrounding vegetation with water, use our cleaning solutions responsibly, and perform a thorough rinse of all plants and landscaping after the job is complete to ensure everything is left unharmed.
In our New England climate, we recommend a professional concrete cleaning every 1 to 2 years. This preventative maintenance stops the damaging and unsightly buildup of algae and grime, keeping your property safe and looking its best year-round.
Our process is highly effective on organic stains like algae and mildew. For inorganic stains like rust and deeply penetrated oil, our specialized treatments can significantly lighten or often completely remove them. We can assess these specific stains during your free estimate.
While bleach can temporarily lighten stains, it does not penetrate the pores of the concrete to kill the organism’s root system. It is also highly corrosive and can damage your landscaping if not used and neutralized correctly. Our professional-grade detergents are more effective and safer for your property.
No, you do not. As long as our technicians have access to the areas that need to be cleaned and an accessible outdoor water spigot, we can complete the entire service while you are at work or away.
Yes. Algae, moss, and other growths can hold moisture against the concrete, accelerating wear and tear, especially during freeze-thaw cycles in the winter. By keeping your concrete clean, you are helping to preserve its structural integrity and prolong its lifespan.
