Frequently Asked Questions
What's the difference between composite and wood decks?
Composite decks require less maintenance and resist moisture damage better than wood, but wood offers a traditional look and can be refinished. Both materials can be used for custom wraparound and multi-level designs. At RPM Pro Service, we build with both composite and wood based on your preference and budget.How often should you stain and seal a wood deck?
Most wood decks in Waxhaw, NC should be stained and sealed every 2–3 years to prevent moisture damage and UV degradation. High-traffic decks or those with full sun exposure may need annual treatment. Regular maintenance extends the life of your deck and keeps it looking new.What causes wood deck boards to rot?
Rotted wood is typically caused by prolonged moisture exposure, poor drainage, or lack of protective sealing. In North Carolina's humid climate, moisture can penetrate unsealed wood and lead to decay. At RPM Pro Service, we replace rotted boards and apply protective sealing to prevent future damage.Can you repair just part of a deck or does it need replacing?
Many decks only need partial repairs, such as replacing rotted boards or fixing structural components, rather than full replacement. A professional inspection identifies which areas are compromised. RPM Pro Service specializes in targeted deck repair that restores safety and appearance without unnecessary costs.How long does a custom deck take to build?
A standard custom deck typically takes 1–2 weeks to complete, while multi-level or wraparound designs may take 3–4 weeks depending on complexity and weather. Proper site preparation and material selection affect the timeline. At RPM Pro Service, we provide a detailed schedule before starting construction.What does a 25-year structural warranty cover on a deck?
A 25-year structural warranty covers the integrity of the deck's framing, posts, beams, and load-bearing components against defects and failure. It does not typically cover surface finishes, stains, or cosmetic wear. RPM Pro Service backs all custom deck builds with this comprehensive structural guarantee.Why is site grading important before building a deck?
Proper grading ensures water drains away from the deck foundation, preventing moisture buildup, wood rot, and structural settling. Poor drainage can undermine posts and cause long-term damage. At RPM Pro Service, we perform precise land grading and drainage solutions before every deck installation.What's the benefit of a screened-in porch versus an open deck?
A screened-in porch offers protection from insects, pollen, and light rain while still providing outdoor airflow and views. Open decks provide more sun exposure and easier furniture flexibility. RPM Pro Service designs both screened-in and covered porches to fit your lifestyle and climate needs in Waxhaw.How does refinishing extend the life of an old deck?
Refinishing restores the protective barrier on wood, sealing out moisture, UV rays, and mold that cause decay. It also improves appearance and can add years to the deck's usable life. At RPM Pro Service, our refinishing process includes staining, sealing, and repairing damaged boards for lasting results.Can you add a new level to an existing deck?
Yes, multi-level expansions can be added to existing decks if the foundation and structure are sound. This requires careful planning to match materials, ensure proper support, and integrate drainage. RPM Pro Service evaluates your current deck and designs seamless multi-level additions.What's the biggest mistake homeowners make with deck maintenance?
The most common mistake is skipping regular sealing and staining, which leaves wood exposed to moisture and sun damage. Even composite decks benefit from periodic cleaning and inspection. At RPM Pro Service, we recommend a maintenance schedule tailored to your deck material and local Waxhaw climate.Does a new deck or porch increase home value?
Yes, a well-built deck or porch can increase home value by enhancing curb appeal, expanding usable living space, and improving outdoor functionality. Custom designs with quality materials offer the best return on investment. RPM Pro Service builds porches and decks designed to boost both enjoyment and resale value.
