Whether your deck needs a few damaged boards replaced, loose railings repaired, stairs corrected, or a complete cleaning and refinishing treatment, our team can help evaluate the condition and develop an appropriate repair and maintenance scope.

Deck Board Replacement
Individual deck boards can become cracked, split, warped, loose, or deteriorated from years of exposure.
When the surrounding framing remains suitable for continued use, localized deck board replacement may be an option instead of replacing the entire deck.
Board replacement may include:
Removing damaged boards
Inspecting accessible framing beneath the repair area
Installing replacement decking
Securing boards with appropriate exterior fasteners
Preparing repaired areas for finishing when included
New replacement lumber may initially differ in appearance from older, weathered decking. Color and appearance may become more uniform over time, but an exact match cannot always be guaranteed.
Deck Railing and Stair Repairs
Loose railings, damaged stairs, deteriorated posts, and failing stringers can affect the safe use of a deck.
Repair work may include:
Loose railing sections
Damaged railing posts
Handrail repairs
Baluster replacement
Stair tread replacement
Stair stringer repairs
Stair stringer replacement
Landing repairs
Structural blocking and attachment repairs
If the existing railing or stair configuration does not meet applicable current requirements, additional modifications may be recommended depending on the scope and local jurisdiction.
Structural Deck Repairs
Visible surface damage can sometimes indicate deterioration in the framing below.
Home Pros STL LLC can evaluate accessible components such as:
Joists
Rim joists
Beams
Posts
Ledger areas
Blocking
Connections
Structural hardware
Localized structural repairs may be possible when damage is limited.
Decks with widespread deterioration, significant movement, questionable footings, or multiple damaged structural components may require a larger repair scope, professional evaluation, or full replacement.
Deck Cleaning and Surface Preparation
Proper preparation is an important part of a deck staining or sealing project.
Depending on the existing condition and approved scope, preparation may include:
Surface cleaning
Removal of dirt and organic buildup
Reduced-pressure washing where appropriate
Removal of loose or failing finish
Spot sanding
Surface sanding
Minor board repairs
Fastener corrections
Drying time before coating
The exact preparation required depends on the existing finish, age of the deck, wood condition, and coating product being applied.
Deck Staining Services
Stain can improve the appearance of wood decking while providing a protective finish appropriate to the selected product.
Available options may include:
Transparent stains
Semi-transparent stains
Semi-solid stains
Solid-color stains
Product selection depends on the condition of the wood, existing coating, desired appearance, sun exposure, and maintenance preferences.
Older decks with uneven weathering or previous coatings may not accept stain uniformly without additional preparation.
Deck Sealing Services
Deck sealers are designed to help reduce moisture absorption and weather exposure when applied to suitable, properly prepared wood.
Sealing may be appropriate for:
New pressure-treated decking after sufficient drying
Previously untreated wood
Prepared existing decking
Certain repaired deck surfaces
New pressure-treated lumber should be allowed to dry sufficiently before applying coatings. The required waiting period varies based on moisture content, weather conditions, lumber type, and coating manufacturer recommendations.
Staining and Sealing Existing Decks
Previously coated decks may require more preparation than newer or unfinished wood.
Existing conditions may include:
Peeling stain
Faded coatings
Uneven coloration
Mildew or algae
Surface graying
Previous solid coatings
Multiple layers of old finish
In some cases, complete removal of an existing coating may be necessary before another product can be applied successfully.
The final appearance can also vary due to wood age, previous coatings, repairs, and natural variations in the decking.
Deck Repair Before Refinishing
Staining or sealing deteriorated wood does not correct structural or carpentry problems.
Before refinishing, damaged components should be evaluated and repaired where necessary.
This may include replacing rotted boards, correcting loose fasteners, repairing railings, reinforcing framing, or addressing other visible concerns.
Applying a finish over deteriorated materials may improve appearance temporarily but does not restore damaged structural wood.
Deck Maintenance in the St. Louis Area
Exterior wood requires periodic maintenance because coatings and sealers naturally wear from sun, moisture, foot traffic, and seasonal weather.
The appropriate maintenance schedule depends on:
Deck exposure
Type of wood
Previous finish
Product used
Shade and tree coverage
Foot traffic
Drainage
Overall deck condition
Periodic cleaning and inspection can help identify developing repair needs before they become more extensive.

Deck Repair, Sealing & Staining Costs in St. Louis
Pricing depends on the size and height of the deck, condition of the wood, extent of repairs, accessibility, preparation required, existing coatings, and selected stain or sealer.
Home Pros STL LLC can often provide preliminary pricing when sufficient photos, measurements, and project information are available.
