This is one of the most common questions homeowners search for before booking a patio cleaning service. The concern is legitimate. Patios are a real investment. Using the wrong equipment or cleaning method on the wrong surface can cause damage ranging from cosmetic to costly.
Start With the Material
The most important thing to establish before cleaning any patio surface is what it is made of. Common patio materials in Northumberland County homes include poured concrete, concrete pavers, brick pavers, and natural stone, including bluestone, flagstone, and travertine. If you are not certain what your patio is made of, a professional can identify it during an assessment before providing a quote.
Use the Right Cleaning Solution for the Surface
Cleaning solutions are not interchangeable across patio materials. Acidic cleaners dissolve calcium-based materials, which can damage limestone, travertine, and concrete. Alkaline cleaners are effective for removing biological growth on most concrete and paver surfaces. A professional cleaning company selects the appropriate solution for the specific material.
Manage the Pressure Carefully
Too much pressure on concrete pavers blows joint sand out of the joints, leaving pavers unstable. Too much pressure on natural stone etches the surface. Too much pressure on sealed surfaces strips the sealer. Even on poured concrete, a pressure wand held too close to the surface can etch the concrete finish.
The correct tool for poured concrete is a commercial surface cleaner that distributes pressure evenly. For pavers and stone, the pressure is reduced further.
Protect Adjacent Surfaces and Vegetation
Professional cleaning includes wetting down adjacent vegetation before applying any cleaning solution, applying the solution to minimize overspray, and rinsing the vegetation again after the cleaning is complete.
The Case for Professional Cleaning Over DIY
Consumer pressure washers deliver enough force to damage pavers and some stone surfaces. They do not deliver the cleaning solution application and dwell time that produce results that last. The risk-to-reward calculation for DIY patio cleaning on anything other than basic poured concrete is not favorable for most homeowners.
