Your deck should be a place to relax, not an eyesore covered in mold and grime. Halo Pressure Washing restores wood and composite decks to their original beauty — and preps them perfectly for staining or sealing.
Not all deck cleaning is the same. The material your deck is made from determines exactly how it should be cleaned — and what pressure is safe to use. At Halo Pressure Washing, Carter assesses each deck individually before we ever turn on the equipment.
Wood decks are porous and absorb moisture, making them highly susceptible to mold, mildew, algae, and graying from UV exposure. Over time, untreated decks develop a dark, slippery surface that's both unattractive and dangerous.
We clean wood decks with calibrated pressure — enough to remove embedded grime and organic growth without raising the grain or splintering the surface. We often pair cleaning with a brightener treatment that opens the wood grain and prepares it to accept stain or sealant evenly.
Composite decking is designed to be low-maintenance, but it still collects mold, mildew, pollen, and general grime — especially in the textured grooves that mimic wood grain. These grooves are hard to clean manually but respond well to targeted pressure washing.
Composite decks require lower pressure than wood to avoid surface damage. We use the appropriate settings and cleaning solutions specifically formulated for composite materials, leaving your Trex or TimberTech deck looking like new without voiding manufacturer warranties.
If you're planning to stain or seal your deck this season, a professional cleaning first is not optional — it's essential. Applying stain or sealant over a dirty surface leads to poor adhesion, uneven color, and a finish that peels prematurely. You're essentially wasting your money on the product.
A properly cleaned deck allows stain to penetrate evenly into open wood pores, creating a bond that lasts. Our deck cleaning service removes not just surface dirt but also old failed sealant residue, tannin staining, and gray oxidized wood fibers that prevent proper penetration.
We recommend allowing the deck to dry for 48–72 hours after cleaning before applying any stain or sealant. For best results, use a penetrating oil-based stain appropriate for Raleigh's humidity levels. If you need a recommendation, Carter is happy to point you in the right direction — call (910) 538-6552.
We walk the deck, check for damaged boards, assess the material type and condition, and identify any areas requiring special attention before we begin.
We move or protect any furniture, potted plants, and surrounding landscaping. We cover what can't be moved to prevent any cleaning solution contact.
We apply an appropriate cleaning solution — mold/mildew cleaner for wood, composite-safe formula for synthetics — and allow it to dwell and break down organic growth.
We clean the deck at calibrated pressure, working with the grain on wood decks, paying attention to railing balusters, posts, and stairs as well as the deck surface itself.
A thorough rinse removes all cleaning solution residue. We do a final walkthrough with you to ensure you're happy with the results before we pack up.
Deck cleaning in Raleigh is priced based on the size of the deck (square footage), the material type, and the level of cleaning required. A standard residential deck cleaning typically runs between $150 and $350.
A typical back porch or small deck — usually $150–$200. Quick turnaround, same professional results as larger projects.
Most standard residential decks fall in this range — expect $200–$300 depending on materials and condition.
