If you have a brick or concrete paver patio, driveway, or walkway in Mobile, you already know what a humid Alabama summer does to them. Give it one season and the joints start turning green. Give it two and you've got black algae, ant sand pouring out from between the pavers, and a surface that looks like it belongs behind an abandoned building on Government Street rather than in front of your home. We're Baldwin Preaux Wash, and paver cleaning and sealing is one of the jobs we do most often across Mobile, from Midtown and Spring Hill all the way out toward West Mobile and Tillman's Corner.
Why Mobile Pavers Get Dirty So Fast
Mobile sits in a near-constant state of moisture. Between the bay humidity, afternoon thunderstorms from June through September, and the heavy tree canopy that shades most of Spring Hill and Midtown, paver surfaces stay damp longer than almost anywhere else in the state. That moisture is exactly what algae, mold, and mildew need to take hold. The porous surface of a concrete or brick paver holds that moisture in, so once organic growth gets started it spreads fast, especially in the grout joints. Without a proper sealer locking those pores down, you're fighting a losing battle with a garden hose.
Our Paver Cleaning and Sealing Process
We don't just blast pavers with high pressure and call it done. That approach strips sand from the joints, loosens older pavers, and can etch softer brick. Our process is built around doing the job right the first time so you're not calling us back in six months because the sealer peeled or the joints washed out.
Step 1: Surface Cleaning
We start with a controlled low-to-medium pressure wash using surface cleaner equipment. This lifts the bulk of algae, dirt, oil, and organic staining without blowing out joint sand or chipping the paver edges. For stubborn mold or mildew, which is almost guaranteed on shaded patios in the 36606, 36607, and 36608 zip codes, we pre-treat with an appropriate cleaning solution and let it dwell before washing.
Step 2: Joint Re-Sanding
Once the surface is clean and fully dry, we inspect the joints. On most Mobile patios and driveways that haven't been maintained, the joint sand is partially gone, washed out over time or displaced by ant activity. We re-sand with polymeric sand before sealing. This step matters because the sealer locks the sand in place permanently. If you skip it and seal over hollow joints, you've just sealed in the problem.
Step 3: Sealer Application
We apply a penetrating or film-forming sealer depending on the paver material and what the homeowner wants for sheen level. Most folks in Midtown and Spring Hill prefer a natural or low-gloss finish that doesn't look wet or plastic. Coastal homeowners sometimes want a wet-look sealer to make the color pop. Either way, the sealer is the part that does the long-term work, blocking moisture, inhibiting future organic growth, and making the surface easier to clean going forward.

Neighborhoods We Service in Mobile
We run crews throughout Mobile on a regular schedule. Paver jobs come up most often in neighborhoods with older or established landscaping where tree cover keeps surfaces shaded and damp. Here's where we've been working recently:
- Spring Hill (36608), Older brick paver driveways and circular entries are common here, and they need attention every two to three years.
- Midtown Mobile (36606, 36607), Courtyard-style paver patios in older homes near Dauphin Street and Airport Boulevard see heavy mold growth under tree canopy.
- West Mobile and Tillman's Corner (36619), Newer construction with concrete pavers often has joint sand that hasn't been sealed since install.
- Old Dauphin Way Historic District, Brick walkways and rear patio areas with heavy moss accumulation from year-round shade.
- Cottage Hill Road corridor, Mix of residential and commercial paver entries that need both cleaning and re-sealing.
- South Mobile toward Bellingrath and Theodore (36582), Paver pool decks and outdoor living spaces that take a beating from summer humidity and foot traffic.
How Long Does the Sealer Last in Mobile's Climate?
That's the honest question everyone should ask before spending money on sealing. In Mobile's heat and humidity, a quality penetrating sealer on concrete pavers typically holds well for two to four years before reapplication makes sense. Film-forming wet-look sealers can start showing wear sooner if the surface gets heavy foot traffic or direct afternoon sun. Brick pavers, which are less porous, often hold up longer. We'll tell you exactly what to expect based on your specific material and exposure when we quote the job, no upselling, just straight talk.
What Happens If You Just Clean and Don't Seal?
Cleaning without sealing still looks great for a few months. But without a sealer closing off those pores, the algae and mildew come back faster than they would on a freshly installed surface because the cleaning process can open the pores slightly. If you're on a budget and can only do one or the other right now, cleaning still makes sense. But pairing cleaning with sealing is the move that keeps Mobile homeowners from calling us back every single spring. Think of the sealer as the maintenance plan, not a luxury add-on.

We also handle commercial paver surfaces, retail entries, restaurant patios, hotel courtyards, and office park walkways.

Frequently Asked Questions
How much does paver cleaning and sealing cost in Mobile, AL?
Pricing depends on the square footage, the condition of the joints, and whether re-sanding is needed. Most residential patio and driveway jobs in Mobile fall in a range that makes sealing well worth it compared to replacement costs. Call (251) 978-5503 for a free on-site quote, we don't price jobs blind.
How long does the sealer take to cure in Mobile's humidity?
Most penetrating sealers are dry to foot traffic within a few hours and fully cured within 24 to 48 hours. We schedule jobs to avoid rain in the forecast and will always give you a clear window for when you can use the surface again.
Can you clean and seal pavers if they're already really moldy or stained?
Yes. We pre-treat heavy organic growth with appropriate cleaning agents before washing. Most mold and algae staining comes up completely. Some older oil stains or iron stains may lighten but not disappear entirely, we'll tell you upfront what to expect.
Do I need to move outdoor furniture and potted plants before you arrive?
We ask that you move any furniture, planters, or decorative items off the paver surface before we arrive. If that's difficult, let us know when you book and we can work around it, though it may add time to the job.
Will pressure washing damage my older brick pavers?
Not when it's done correctly. We use controlled pressure and surface cleaner equipment specifically to avoid chipping edges or blowing out joint material. Older and softer brick gets lower pressure with longer dwell time on cleaning solution. We've worked on historic brick pavers in Midtown and Old Dauphin Way without incident.
How often should paver surfaces in Mobile be resealed?
In Mobile's humid climate, plan on every two to four years for concrete pavers and every three to five years for harder brick pavers in low-traffic areas. High-traffic driveways and commercial entries may need attention sooner. We can assess your surface when we clean it and give you a realistic maintenance timeline.
