Wood Decks
We clean pressure-treated wood and other wood decks, depending on the type and its condition. Before we start, we check the age, the finish and the current state of the boards. A cleaning freshens the look and lifts dirt and growth. It is not a restoration, and we do not promise a like-new result on old or weathered wood.
Professional Deck Washing Across the Connecticut Shoreline
Kells Window Cleaning is a Madison-based company serving homes across the Connecticut shoreline. Deck washing is one of our regular services. Most homeowners book it when the deck looks dull or green, or before they plan to reseal or stain it themselves.
We handle residential deck washing, and we pick the method to match your deck material and its current state. A newer composite deck and an older wood one need different handling. Before any cleaning starts, we confirm the scope and a clear price, so you know what the job covers.
Our deck washing services across Shoreline CT focus on cleaning. The service does not include repairs, staining or sealing unless we confirm that separately. We clean the deck. What it looks like afterward depends on the wood and its condition.
Wood and composite decks are not cleaned the same way. Here is how we approach each.
Deck Materials We Clean

Composite Decking
Composite decks still gather dirt and algae, especially in shaded spots. We pick the cleaning method to suit the product and its finish. Composite materials vary, so we assess yours first rather than assume one method fits all. Where stairs, railings and detailed areas are part of the job, we include them in the estimate.
Buildup Found on Shoreline Decks
Decks near the coast collect a particular mix of buildup. Here is what deck washing helps clear.

Algae and Mildew in Damp Areas
Shaded boards, areas under trees and moisture-prone sections are where algae and mildew gather. These spots stay damp longer, so growth takes hold there first. A deck wash loosens and clears that buildup with a method suited to the surface.

Coastal Salt and Seasonal Pollen
Decks on exposed shoreline properties may collect salt residue. Seasonal pollen adds to it in spring. A wash clears the surface residue. Older marks or a damaged finish may not fully clear, and we tell you what to expect before we start.

Dirt, Organic Buildup and Foot Traffic
Everyday outdoor grime and ground-in dirt build up with regular use. A deck wash lifts this general buildup and freshens the boards. It does not guarantee the removal of paint, oil or permanent stains, since those depend on the surface and how deep they go.
A Careful Cleaning Method for Every Deck
Getting deck washing right means matching the approach to the material. Here is how we work.
1
Inspecting the Material and Current State
We start by looking at the deck. We check the material, the existing finish, any weathered or damaged areas, and how easy the deck is to access. That tells us the safest way to clean it. Every deck is a little different.
2
Choosing the Method, Solution and Pressure
Based on what we find, we choose a controlled method suited to the material. Not every deck is cleaned the same way, so we set the approach and pressure to match. Where a cleaning solution suits the surface, we use one appropriate to the deck.
3
Preparing the Surrounding Area
Before we begin, we take care to protect nearby plants, outdoor furniture, railings and property features. Deck washing involves water, so a little preparation keeps the surrounding area clear while we work.
