5 Signs Your Riverview, FL Home Exterior Needs Professional Pressure Washing

June 10, 2025

Living in Riverview, FL, we know firsthand how our unique climate can put our homes’ exteriors through the wringer. Hot, humid summers, nearly daily summer thunderstorms, and sun-drenched days combine to create the perfect storm for dirt, mold, algae, and other unsightly buildup to thrive on every surface—driveways, fences, pool enclosures, and beyond. As the owner of Riverview Pressure Cleaning, I’ve seen it all. Below, I’ll walk you through the top signs we look for to determine when it’s time to call in the professionals—and why acting early can save your home, your wallet, and your curb appeal.

1. Noticeable Black or Green Streaks and Spots

One of the most obvious warning signs in the Tampa Bay area is the appearance of dark streaks or green patches on your siding, soffits, roof, or fences. These are rarely just dirt—they’re usually molds or algae feeding on moisture, pollen, and dust. On roofs, the culprit is often the blue-green algae Gloeocapsa Magma, which can cause shingles to deteriorate, darken, and age prematurely. On vinyl or PVC fences, it’s a mix of green algae and mildew. If left alone, these organisms don’t just look ugly—they can eat into your home’s paint, materials, and structure.

  • Riverview, FL’s humidity accelerates growth: Black mold can set in within months after wet season if not addressed.
  • Driveways and walkways: Black spots here are usually colonies of mold or algae, often made worse by overspray from sprinklers.



Our approach? We use professional-grade pressure washers paired with the right eco-friendly cleaning solutions. On wood, we avoid bleach and use non-harmful agents. On vinyl, we employ solutions that kill growth down to the root—giving you longer-lasting results.

2. Slippery or Gritty Surfaces Underfoot

Have you ever noticed your driveway feels slick when it rains, or maybe your pool deck “grabs” at your shoes? That’s a major sign of built-up grime, algae, or mineral deposits. In shaded areas, especially on north-facing concrete and paver surfaces, algae spreads quickly in our tropical climate. It’s not just unsightly—these surfaces become a real slip hazard for families, especially around pools and entryways.

  • Slick sidewalks are a primary cause of falls, and many HOAs require routine cleaning for this reason.
  • Pebbly, gritty surfaces can neither be swept nor hosed away; the embedded dirt can only be fully removed with high-pressure surface cleaning equipment.



At Riverview Pressure Cleaning, we use large surface cleaners and controlled chemical rinses that both lift the residue and penetrate the pores of your concrete, ensuring mold and algae don’t return immediately.

3. Faded, Dull, or Dirty Curb Appeal

First impressions matter, and your home’s exterior is what neighbors and guests notice first. Over time, Florida’s punishing sun, pollen from oaks and pines, and grime from passing storms dulls paint, alters colors, and leaves surfaces looking older than they really are. If you see any of the following, it’s time to act:

  • White fences turning yellow or streaked.
  • Siding that’s lost its “pop.” (Trust us, dull paint is often just dirty paint.)
  • Rust-colored stains from irrigation overspray or water sitting on concrete or walls.
  • Window and door frames accumulating brown/green lines, especially after a stormy season.



Routine exterior cleaning not only restores color but extends the life of your paint and finish—potentially delaying repainting by years.

4. Musty Odors or Unexplained Allergies

Often, the smells and sneezes you experience in and around your Riverview home aren’t just “seasonal allergies”—they can result from mold, mildew, or bacteria thriving on dirty exterior surfaces. Entryways, pool cages, and lanais that haven’t been cleaned recently tend to trap moisture, dust, and organic material. This soggy debris is home to:

  • Mold spores, a top indoor/outdoor allergen.
  • Fungal growths that seep from outside in, especially after rain or irrigation.
  • Musty, earthy smells near doorways or lanai screens.



As a local operator, we know how frustrating and persistent these odors and symptoms can be. Our process includes a thorough wash down and preventive treatment for pool cages and lanais, and we stand by our 30-day satisfaction guarantee for cage and screen cleaning.

5. Pool Cage, Screen, or Fence Maintenance Has Fallen Behind

Pool cages, screens, and fences are unique to Florida-style living—and they require a Florida-specific care approach. With our lengthy growing season, algae, lichen, and mildew accumulate incredibly fast on these surfaces. White PVC fences look great new, but their smooth surface means even thin films of algae or mold show up quickly. Wood fences, on the other hand, are prone to deep stains and should never be washed with harsh chemicals or high pressure. For both:

  • If the fence or cage looks noticeably dirtier at the bottom, that’s trapped moisture and shade providing a perfect algae environment.
  • Long intervals between cleanings result in thicker, tougher buildup—and higher cleaning costs.
  • Past-due cages or screens can incur HOA warnings or even fines in stricter neighborhoods.



We tailor our cleaning solution to your materials, including a non-bleach strategy for wood and a gentle but deep cleaning for vinyl or aluminum.

Bonus: When to Schedule Pressure Washing in Riverview, FL

Timing matters just as much as frequency. Through years of hands-on local experience, our advice is:

  • Before summer storm season: May–June cleanings help protect surfaces before heavy rain, wind, and debris hit.
  • After pollen season ends: February–March cleaning removes a season’s worth of sticky, yellow-green pollen and prepares your home for spring gatherings.
  • Following landscaping changes or home improvement: Construction dust, soil from new beds, and irrigation overspray are best handled promptly to avoid permanent stains.



For most households, one full service per year keeps everything safe, healthy, and looking fresh—though certain exposed or shaded areas might need a mid-year touch-up.

How Professional Pressure Washing Makes a Difference

Many homeowners try to tackle buildup with off-the-shelf pressure washers or harsh cleaning agents. Unfortunately, that approach risks not only incomplete cleaning but also permanent damage to paint, screens, and even shingles. With Riverview Pressure Cleaning, you get:

  • Custom-adjusted pressure and solution—matched to each surface for optimal safety and effectiveness.
  • Trained, licensed, and insured expertise. Our owner-operator, Chris, brings 12+ years of local knowledge to every job.
