If you own a house in Mobile, you have probably heard a neighbor swear by some questionable pressure washing advice. Pump up the PSI. Hit the brick hard. Get the contractor with the biggest rig in the driveway. We work through Mobile every week, from the 36604 streets of Oakleigh and the Lafayette historic district to the Spring Hill cottages off Old Shell Road and the West Mobile cul-de-sacs in 36695, and almost every estimate starts by walking a homeowner back from one of these myths. Here are the six we hear the most, and what a job done the right way actually looks like on a Mobile home.
Myth 1: More PSI means a better clean
This is the most common one. A 4,000 PSI cold-water pressure washer pointed at painted hardiplank in West Mobile will pit the surface in a single pass, blow water behind the siding, and leave streaks that come back darker the next month. The contaminants that make a Mobile home look dirty are biological: gleocapsa magma algae on north-facing walls, mildew under the eaves where humidity collects, and an oily film from the pollen-and-exhaust combination that settles on every west-facing surface in 36608. None of that responds to brute force. It responds to chemistry plus a calm rinse.

Myth 2: Pressure washing damages historic Mobile brick
Old Mobile brick in the Oakleigh Garden District, around Lafayette Street, and on the homes off Government Boulevard near the Cathedral Square radius can be a hundred years old. Homeowners hear "do not pressure wash brick" and freeze. The right answer is more useful: do not blast brick at high pressure. A low-pressure soft wash with the correct chemistry pulls a century of algae and grime off without disturbing the mortar joints or the soft-fire surface of the brick itself. We have done this on homes in 36602 and 36604 without a single complaint from the historic preservation crowd, because we work the same way they would: gentle solution, careful dwell, low-pressure rinse, no high-impact tip ever touching the wall.
What you should ask the contractor
Ask three questions before anyone touches your brick. What PSI at the wall? What chemistry on the algae? What is the rinse plan to prevent runoff streaks on the limestone water table? If the answer to any of those is a shrug, do not hire the crew.
Myth 3: A house wash and a roof wash are the same job
They are not. A house wash gets the siding, soffits, fascia, and the trim under the eaves. A roof wash treats the shingles, ridge caps, and the valleys where algae builds up. Spring Hill homes off Old Shell Road and the cottages near Spring Hill College tend to need both, but at different cadences. The house wants annual cleaning to keep mildew off the north and east walls. The roof wants a soft-wash treatment about every three years to clear gleocapsa streaks. Combining them into one flat quote almost always means the contractor will skim the harder job and leave you disappointed in six months.

Myth 4: Driveway cleaning is just a quick pass
Mobile driveways collect three things that make them ugly: tire-track oxidation from the daily commute, rust stains from the metal furniture and sprinkler heads that have been sitting on the slab, and a layer of algae fed by the constant Mobile humidity. A single high-pressure pass leaves "tiger stripes," the marks where the wand swept faster on one side than the other. The right pass uses a surface cleaner that distributes pressure evenly across a 16 or 20 inch swath. You see this on Cottage Hill Road properties where the driveway is 60 feet long and an even finish actually matters to the curb appeal.
Myth 5: You can do it yourself with a $300 Home Depot rental
For a sidewalk or a small back patio, sure. For an entire house in 36608 or 36695, the rental will let you down before you finish the first wall. Most consumer pressure washers cap out at 2.5 GPM. Without flow, you cannot rinse the chemistry off the wall before it dries, and dried soft-wash chemistry on hardie siding leaves streaks that need a second visit. We carry a 5.5 GPM rig because that is what it takes to do a Mobile house in one trip. The homeowner version exists to clean lawn chairs.
The cost difference, honestly
A pro house wash on a 2,400-square-foot Mobile home runs about the price of a nice dinner out for four. Renting the wrong rig, buying the wrong chemistry, taking a Saturday off work, and risking damage to a recently painted exterior usually costs more in the end, and the result almost never matches what the professional pass would have produced.
Myth 6: All Mobile contractors do the same thing
If two contractors show up with the same trailer, the same pump, and the same answer to every question, they are not the same. The differences are in the chemistry, the rinse discipline, the substrate awareness, and the comfort with high-end finishes. A Spring Hill home with a stucco accent wall, real cedar shake siding on the dormers, and decorative cement-board panels on the porch is not a one-recipe house. The crew you hire should be able to look at it, name the three substrates, and tell you the cleaner blend they would use on each before they ever quote the price.

What a real Mobile, AL job day looks like
We start at the back, never the front. The reason is simple: if the chemistry behaves unexpectedly on the back-of-house siding, you do not want that surprise on the streetside elevation. We do a full walk with the homeowner before any water flows: AC condenser locations, painted patio furniture that needs to be moved, the spigot we are tapping, the saved cuttings the homeowner does not want overspray on. Then we soft-wash the siding section by section, give each wall a 5 to 7 minute dwell, and rinse low-pressure with the flow rate to clear the chemistry completely. A standard Mobile house with no roof in the package takes a four-person crew about three hours.
Routes we run weekly
Most weeks we are running back-and-forth across the bay from the Causeway. Tuesday mornings tend to land in Midtown Mobile around 36604. Wednesdays we are usually up in Saraland or Satsuma along US-43. Thursday is often Spring Hill or West Mobile, with stops on Schillinger or Cottage Hill Road. If you are in one of those neighborhoods and you can give us a flexible day for the visit, we can usually get you scheduled inside of two weeks even during the May to August peak season.

Frequently Asked Questions
Will pressure washing damage my historic Mobile brick home?
Not if it is done as a soft wash. We use a low-pressure application, the right chemistry for the algae and grime on the brick, and a careful rinse. The high-PSI blast that damages brick comes from contractors using a turbo nozzle and a 4,000 PSI cold-water rig. That tip should never touch historic masonry. Ours does not.
How often should a Mobile, AL house be cleaned?
For most homes in Spring Hill, West Mobile, and Midtown, once a year on a fall or late-spring schedule is the right cadence. Homes under heavy oak shade or near Mobile Bay where humidity sits longer often want a check at six months. The roof can wait two to three years between treatments if you stay on top of the house wash.
Is soft washing safe for painted siding and stucco?
Yes. Soft washing uses low pressure (under 500 PSI at the wall) with a paint-safe biocide blend. The cleaner does the work; the rinse just carries it off. Properly applied, soft wash does not strip paint, gouge stucco, or push water behind hardiplank. We have cleaned thousands of homes this way across Mobile, Baldwin, and Pensacola without a single substrate-damage callback.
Do you clean both the house and the driveway in one visit?
Yes, and we typically do. Bundling the two saves you a second mobilization charge and gives the driveway a chance to dry while we are working the upper elevations. Just tell us during the quote so we bring the surface cleaner and the right rust-and-oil chemistry along.
Can you clean homes in 36602, 36604, or other downtown Mobile zip codes?
Yes. We work the historic districts regularly, including Oakleigh, the Lafayette Street area, and the homes around Cathedral Square. We tarp landscaping, coordinate with the neighbor on shared property lines, and stage water so the crew is not running hoses across pedestrian sidewalks.
