Answers to what homeowners ask us most.
Yes — quotes are always free with no obligation. Fill out our contact form or give us a call, and we'll typically get back to you within 24 hours to set up an estimate.
Pricing depends on the size of the area, the level of buildup, and which service you need. We have a $250 minimum job cost, and we provide upfront, transparent pricing before any work begins — no hidden fees.
Yes. We use soft washing techniques and eco-friendly, biodegradable cleaning solutions for delicate surfaces like siding and decks, so your property, plants, and pets stay safe throughout the process. We also rinse nearby plants and landscaping before and after applying any cleaning solution, giving extra protection.
Power washing uses high-pressure water to blast away dirt and grime — ideal for tough surfaces like concrete driveways and walkways. Soft washing uses lower pressure combined with cleaning solutions, which is gentler and better suited for house siding and other delicate surfaces.
Not necessarily — as long as we have access to the areas being cleaned and a water source, we can complete most jobs without you being present. We'll coordinate the details with you ahead of time.
With a typical soft wash treatment, it can take 2-3 years before mold and algae start to reform — though this varies depending on factors like sun exposure, rainfall, wind, and how shaded your property is. Flat surfaces like driveways and patios tend to hold onto moisture longer, so it's not uncommon for mold or algae to return sooner in those areas.
We proudly serve Lancaster, Lititz, Ephrata, Elizabethtown, Manheim, Mount Joy, Denver, Adamstown, East Earl, and the surrounding Lancaster County area.
Depending on the severity and timing of the rain, we may still be able to complete the job as scheduled. If a storm or heavy rainfall is expected, we'll reach out ahead of time to discuss rescheduling.
