Pressure Washing for Paint Prep

Pressure washing is often the first step in preparing an exterior for painting or staining. Dirt, chalky residue, moss, mildew, and loose material can all interfere with proper adhesion, even when high-quality coatings are used. If those contaminants aren’t removed, paint is more likely to peel, wear unevenly, or fail prematurely.


Our pressure washing services for paint prep focus on creating clean, stable surfaces without damaging the material underneath. We remove buildup from siding, trim, decks, and other paintable areas so finishes can bond evenly and perform as intended. This approach goes beyond a cosmetic rinse and lays the groundwork for results that look better and last longer.

Exterior Cleaning for Ongoing Home Maintenance

Pressure washing is an important part of exterior home maintenance, not just a cosmetic upgrade. Removing buildup helps prevent moisture retention, surface deterioration, and slippery conditions around the home. 


We clean with the goal of restoring performance while protecting the surface underneath. Pressure and technique are adjusted based on surface type, age, and condition, ensuring effective results without unnecessary wear or damage. If we identify preexisting issues that require repair or replacement, which is common in older homes, we’ll flag them and offer clear recommendations for next steps.


This type of exterior cleaning is often used to:


  • Reduce moss, algae, and mildew growth
  • Improve traction on decks, patios, and walkways
  • Restore the appearance of siding and hardscapes
  • Slow long-term wear caused by trapped moisture

Pressure Washing and Home Maintenance on a Schedule that Works for You

Pressure washing can be scheduled as a standalone service or included as part of a broader exterior maintenance plan. Many homeowners use regular pressure washing to keep surfaces clean between major projects and reduce long-term wear.



With our customizable home maintenance plan, you can choose your preferred frequency based on the tree cover, shade, moisture exposure, and other factors that affect how quickly your exterior accumulates growth and debris. This service also pairs naturally with gutter cleaning, roof maintenance, and exterior repairs to help keep water moving properly and surfaces in good condition.

Siding & Trim Cleaning

Exterior siding collects dirt, mildew, and airborne debris year-round. We provide thorough siding cleaning for wood, vinyl, and fiber-cement surfaces, tailoring pressure levels to the material and age of the finish.



This includes pressure washing vinyl siding as well as painted and stained surfaces. Clean siding not only improves curb appeal, but also helps surfaces dry properly and perform better over time.


Decks, Patios & Walkways

Decks and other horizontal surfaces are especially prone to moss, algae, and mold buildup in damp climates. Our pressure washing services safely clean mildew off decks, remove algae and moss, and restore natural color before staining or sealing.


We also handle pressure washing walkways, driveways, and hardscapes to remove grime and organic growth that can create slippery, uneven surfaces. Keeping these surfaces clear helps reduce slip hazards, slows surface deterioration, and keeps high-traffic areas usable and easier to maintain over time.


Soffits, Fascia & Eaves

Soffits, fascia boards, and eaves often collect cobwebs, dirt, and residue that are easy to overlook. Left uncleaned, buildup in these areas can trap moisture and contribute to premature wear. They’re also especially important to clean before painting, as buildup can lead to uneven coverage and peeling.



Our pressure washing services include careful cleaning of these details to remove residue and buildup that can interfere with surface performance, whether the goal is maintenance or future painting.
