Clean Off Mildew and Pollen Film
Warm, humid air lets mildew settle into deck boards quickly, especially in shaded corners under trees or close to the house where the sun rarely reaches. In spring, pine and oak pollen add a yellow film that sits on the surface and keeps stain from reaching the wood. A wood-safe cleaner, a stiff brush and a thorough rinse remove both without tearing up the grain. Work one section at a time and keep the surface wet while you scrub so the dirt lifts instead of drying back on.
Pay attention to the spots that stay dark after rinsing. Gray or black patches near planters, downspouts or the gaps between boards often mean mildew has worked deeper into the grain. They may need a second pass. If the color still will not even out, it is a sign the surface fibers are worn and sanding will be part of the job.

Let the Wood Dry Completely
Boards hold water longer than most people expect, especially on wooded lots or in yards where clay soil drains slowly. Stain brushed over damp wood traps moisture underneath, and that moisture pushes the finish off as peeling or blotchy patches. After cleaning or a heavy rain, give the deck time. The surface should feel dry to the touch, look even in color and stay dry when you press a clean cloth into a board.
Decks in shaded spots of Windermere or on wooded parcels near Buford Dam Road can take noticeably longer to dry than an open deck in full sun. A few days of breeze and sunshine usually do the job, but the shaded side of the deck is the one to judge by, not the sunny side near the steps.

Sand or Strip the Old Coating
If an older stain or sealer is flaking, peeling or wearing unevenly, new stain applied on top will only last as long as the weakest layer underneath. Sanding removes loose finish and the gray, weathered surface fibers so fresh wood is exposed. For thick or film-forming coatings, a stripper made for exterior wood may be faster, followed by a careful rinse and another full drying period.
The goal is bare, clean wood with an open grain. Run a hand across the boards after sanding; they should feel smooth without fuzzy fibers or slick spots. Railings and stair treads deserve the same attention as the main floor, because hands and feet wear the finish there first.

Pick a Dry Stretch of Weather
Stain needs time to cure without rain, heavy dew or a sudden drop in temperature. Look at the forecast for a stretch of dry days with moderate humidity before you start. Morning application usually works well because the wood absorbs the stain as the day warms, but avoid boards that feel hot under direct sun, since stain can flash dry before it soaks in.
Spring pollen season is a tricky window. A fresh coat can catch a layer of yellow dust before it cures, so many homeowners wait until the heaviest pollen has passed. Early fall often brings steadier weather and cooler afternoons, which suits staining well.

Why Skipped Prep Is the Usual Reason Stain Fails
It is tempting to see new color right away and skip straight to the stain. That shortcut saves an afternoon but tends to cost the whole finish: peeling, fading or blotchy patches show up within a season, and the next round of prep is harder because there is now a failed coat to remove. Cleaning, drying and sanding are what let the stain bond to the wood instead of to dirt or old coating.
Prep also gives you a close look at the structure. While boards are bare and clean, soft spots, loose railings, popped fasteners and cracked stair treads are easier to see. It makes sense to fix those before any finish goes on, so the new stain is not covering a problem.

How B&T Handles Deck Prep and Staining
Breno visits each property in person to look at the wood, note any repairs and talk through stain options that suit the boards and the sun exposure. Our crew handles the full prep: cleaning, drying time, sanding or stripping, then the stain itself. If boards, railings or stairs need repair first, we take care of that so the finished deck is sound as well as good looking.
We work across Cumming, from downtown Cumming to communities such as Vickery and Polo Golf & Country Club, along with nearby Johns Creek, Alpharetta and Milton. Every project starts with a free written estimate so you know the scope before any work begins.
Straight answers
Cumming homeowner questions
What is the difference between deck cleaner and deck brightener?
A cleaner lifts dirt, mildew and pollen. A brightener is often used afterward to even out the color of the wood and help open the grain before stain goes on. Not every deck needs both, and Breno can tell you which steps yours calls for.
How long should a deck dry after washing before it gets stain?
It depends on sun, shade and humidity. An open deck may dry in a couple of sunny days, while a shaded one takes longer. Judge by the darkest, shadiest boards, not the ones near the sunny steps.
Does mildew come back after one cleaning?
It can return if the deck stays damp and shaded. Cleaning removes the current growth, and letting more light and air reach the boards, for example by trimming nearby shrubs, helps keep it away longer.
What if my HOA has rules about stain color?
Many Cumming communities have architectural review, but each association sets its own rules. Check your guidelines or ask the HOA before choosing a color, and share the approved options with us so we can plan around them.
Can I stain over an old solid stain with a semi-transparent one?
Usually not without removing the old coating first. A semi-transparent stain needs to soak into bare wood, and a solid film on top keeps it from reaching the grain.
Is it worth staining a deck that has soft or rotting boards?
Not until those boards are replaced. Stain will not hold on decaying wood, and covering it only hides a problem that keeps growing. We can repair the boards first and then finish the deck.
Why do some boards look gray even after cleaning?
Gray usually means the surface fibers have weathered. That is common on older decks and does not mean the board is bad. Light sanding removes the gray layer so the wood takes stain evenly.
Do railings and stairs need the same prep as the deck floor?
Yes. Hands and feet wear the finish on rails and treads faster than anywhere else, so they need the same cleaning, drying and sanding to keep the new stain from wearing through early.
