Why we assess the deck before estimating it
A square-foot number cannot tell us whether the old finish is sound, whether the boards need stripping and sanding, how much detailed railing work is involved, or which product system is compatible. We inspect those conditions first, then prepare a free estimate around the complete scope.
What shapes the refinishing scope
Two decks of the same size can require different work. The most important factors are:
- Deck condition. Light weathering may need cleaning and compatible recoating. Heavy failed finish can require stripping and extensive sanding before any new finish goes down.
- Stripping and sanding. Peeling coating, raised grain, splinters, and previous product compatibility determine the prep plan.
- Finish selection. Transparent, semi-transparent, and solid systems have different prep, appearance, application, and maintenance requirements.
- Railings and stairs. Balusters, posts, stair treads, and handrails are detailed surfaces that take substantially more hand work than a flat deck floor.
- Access and protection. Height, landscaping, siding, adjacent surfaces, furniture, and material staging affect how the work must be performed.
- Wood vs. composite. Real wood may be refinished. Composite is cleaned according to the product requirements and is not stained.
Prep is the foundation of the finish
A stain job lives or dies on what happens before the finish: cleaning to sound wood, sanding rough or splintered areas, removing failed incompatible coatings, setting loose fasteners, and protecting siding and landscaping.
Skipping prep may look acceptable briefly, but it creates adhesion and appearance problems. That is why our estimate starts with the deck's actual condition rather than a generic measurement alone.
Opacity changes maintenance, not just the look
The finish you choose affects grain visibility, UV protection, and the likely recoat interval:
- Transparent / clear — shows the most wood grain and provides the least UV protection, so it generally needs attention more frequently.
- Semi-transparent — keeps visible grain while adding pigment for UV protection.
- Solid — maximum protection and the longest stretch between recoats. It hides the grain and reads closer to paint, which is ideal for evening out an older, weathered deck. Fewer recoats over the deck's life.
If you want the full breakdown of which opacity fits your wood and sun exposure, it's on the deck staining page.
Composite isn't stained — it's cleaned and brightened
If your deck is Trex, TimberTech, Fiberon, or AZEK, it should not be stained. Composite needs product-compatible cleaning to lift film and mildew without damaging the capped surface. Not sure which material you have? We'll identify it during the assessment.
A maintenance schedule helps prevent rescue work
Real wood performs best when it is inspected and maintained before the finish fails completely. The useful interval depends on product, sun, shade, traffic, moisture, and prior prep—not a universal calendar. See our Northern Illinois timing guide.
Free estimates based on the actual deck
We inspect the deck, explain the required prep, document the proposed finish system, and provide a free estimate for that scope. If the deck needs repair before it is worth finishing, we say so before proposing surface work.
