Frequently asked questions

Removing years of stain and organic growth restores curb appeal immediately, which matters for appraisals, listing photos, and neighborhood impressions. It also prevents the slow material damage that eventually turns cosmetic neglect into structural repair bills nobody planned for.

Most residential house washes run two to four hours, and a standard driveway is usually finished in under two hours with our commercial equipment. Larger properties, heavier staining, and combined service days naturally take proportionally longer to complete properly.

Not at all. We need access to an outdoor water spigot, a clear path around the structure, and closed windows. Many clients across St. Charles Parish simply leave a gate unlocked and come home to a finished property.

Design consultation, professional installation, maintenance calls throughout the season, then complete removal and off-site storage once the holidays end. You never handle a strand, a clip, a ladder, or a storage bin at any point in the process.

No. We own all lights, decorations, and hardware and lease them to you as part of the service, which keeps everything commercial grade, properly fitted to your rooflines, and fully covered by our own maintenance program through the entire season.

August and September are the busiest booking months, with October and November reserved for installations. Reaching Neptune ProWash in Luling, LA early secures your preferred install window and leaves plenty of room to develop a genuinely custom design for the property.

A hardy algae called gloeocapsa magma feeds on the limestone filler in asphalt shingles and spreads downward with rainfall. It is a living colony rather than dirt, which is why rinsing never removes it for long on its own.

Roof first, then siding, then gutters, then flatwork. Working top down means anything loosened above washes onto a surface still waiting its turn, so nothing clean gets dirtied twice and the finished result holds together across the whole property.

House washing pairs naturally with concrete and gutter work, since the same setup covers all three and debris from one lands in the other. Roof washing is best scheduled just before gutters get cleared so nothing washes back into a clean trough.

We can, with a much gentler approach. Failing paint and brittle caulk cannot take force, so those elevations get low pressure and a longer dwell time, and we tell you honestly where cleaning will expose existing damage underneath it.

It does, noticeably. Removing the algae, and pollen film that collects on siding, walkways, railings, and porch ceilings cuts down what gets tracked indoors and what settles on outdoor furniture through spring and early summer each year.

We reschedule at no charge. Steady rain dilutes cleaning solutions before they can work and wind makes ladder work unsafe, so we watch the forecast and move the appointment rather than delivering a compromised result on the day itself.

Yes, routinely. Storefronts, offices, restaurants, warehouses, and multi-tenant buildings all fall inside what we handle, and larger sites are scheduled around business hours so cleaning never disrupts staff, deliveries, or customer access during the normal working day.

We do. Many clients across Luling, Louisiana put house washing, gutter clearing, and concrete cleaning on an annual or twice-yearly rotation, and Neptune ProWash holds the slot so the work never quietly slips past a season or two.

Yes. Every display we install includes a timer so the lights come on and shut off at set hours without anyone touching a switch, which keeps the schedule consistent and saves the energy of running them overnight all season.

A surfactant-based cleaning solution diluted to whatever strength the surface can safely take. Siding and shingles get far gentler mixes than concrete, and every treated area is rinsed thoroughly once the organic growth has released its hold.

Not if the rinse is done properly. Glass gets a final pass with clean water so nothing dries on the pane, and we flag any window that was already spotted or fogged from a failed seal before we start.

Cleaning removes the chalky residue and restores a lot of the original tone, though oxidation is the finish itself breaking down. Badly faded panels come back partially, and at that point painting or replacement is the honest answer.

Yes, with care. Panels themselves get a gentle rinse rather than any pressure, and the roof surface beneath and around the array is treated so runoff carries nothing onto the glass or into the brackets and mounting hardware below.

Sooner than owners expect in this climate. Construction dust, mortar splatter, and the first season of algae all settle within a year or two, and starting a regular cleaning rhythm early keeps the materials from ever falling badly behind.

Very often, yes. Those letters usually cite roof streaking on siding, or a stained driveway, and all three respond to a single scheduled visit that brings the property back inside neighborhood standards well before the stated deadline passes.
