At Keenwick, we clean the patios where you actually spend time outdoors and that take the full force of Maryland weather. From pavers and concrete to brick and stone, we lift away dirt, algae, mildew, and stains using the method matched to your patio surface, so your patio looks bright and inviting instead of dull and grimy.
A patio is one of the most-used parts of your outdoor space, and it takes a lot of abuse from foot traffic, furniture, grilling, and the weather.
Pavers, concrete, brick, and stone each collect buildup differently, and each needs a different approach. Too much pressure can etch soft stone or loosen the sand between pavers, while too little leaves algae and stains behind.
At Keenwick, we identify your patio surface first, then choose the safest effective method, from low-pressure soft washing to careful rinsing, to clean without damaging the surface. Our technicians are background-checked and trained, so you get consistent, careful results on every visit.
We start by walking the patio to identify the surface and any problem spots, protect nearby plants and landscaping, then clean using the pressure and solutions best suited to your patio.
We finish by rinsing thoroughly and checking edges, joints, and transitions so the whole patio looks clean and consistent.
Patio power washing also pairs well with a full exterior refresh. Many homeowners schedule it alongside house washing or a broader residential power washing visit to restore the whole property at once.
Patio power washing works best as part of a full exterior refresh. Here are the related services we offer across Maryland.
Streak-free interior and exterior window cleaning, including sills and tracks. A natural add-on when we are already on-site cleaning your patio.
Safe siding cleaning for vinyl, brick, stucco, and painted wood. Pair it with concrete cleaning to restore the whole exterior in one visit.
Low-pressure soft washing that removes algae, moss, and black streaks without damaging shingles.
Detailed cleaning for window and door screens that clears pollen, dust, and grime, so more light and fresh air reach your home.
Removal of leaves, debris, and buildup from your gutters so water drains away from your roof and foundation the way it should.

Keenwick sent Eric over this morning to power wash our house and he did an incredible job! He showed up within the VERY reasonable 30 minute window, he was polite, left no mess, and did not take nearly as long as I thought it would. 5 stars easy.Posted on Google![]()

Most patios benefit from a professional cleaning once a year. Patios in shaded or damp areas that collect more algae and mildew may need it more often, since that growth can make surfaces slippery and hold moisture against the material over time.
It can, if the wrong pressure or technique is used. Softer stone can etch under high pressure, and aggressive washing can loosen the sand between pavers. That is why we identify your patio surface first and use the lowest effective pressure, often a soft washing approach, to clean safely.
We clean paver, concrete, brick, and natural stone patios, matching the method to the surface. If you have a specific surface in mind, reach out and we will let you know how we would approach it.
In many cases, yes. We use cleaning solutions matched to the buildup, whether it is algae, mildew, or general grime. Some deep or old stains may lighten rather than disappear completely, and we will tell you honestly what to expect before we start.
