Q: Should I clean my deck before sealing it?

Y ou should clean your deck before sealing it. Cleaning before refinishing is critical. If you don’t remove dirt and debris, you'll trap moisture in the wood, which prevents the new sealer from working correctly and can lead to costly repairs. Whether you need to sand, power wash, or sandblast depends on your deck's condition.

Q: Is it better to seal or stain a deck?

Sealing and staining your deck are essential maintenance methods that protect and beautify your outdoor space. Stain adds rich color and guards against fading, while sealant fortifies the wood against moisture and weather damage. Wood type, climate, deck age, and the degree of existing damage determine whether your deck benefits from one or both treatments. Using both options extends your deck’s durability and enhances its overall appearance.

Q: How much does it cost to power wash and seal a deck?

Power washing and sealing your deck costs $500 to $1,700. This process combines the removal of stubborn dirt and debris with a protective seal that preserves the wood’s integrity. Effective cleaning eliminates harmful buildup, and a proper seal prevents moisture damage and wood decay, ensuring long-term durability and reducing future repair expenses.

Q: How often do decks need to be sealed?

Your deck must be sealed every one to three years to maintain its strength and appearance. Regular sealing is essential to protect the wood against moisture, mold, and harmful UV rays. A consistent sealing schedule prevents rapid deterioration and costly repairs. Inspections should be performed annually to determine if the protective layer remains intact, extending the life of your deck.

Q: Can I leave my deck untreated?

Leaving your deck untreated compromises its structural integrity and safety. An unprotected deck rots quickly due to moisture and environmental exposure, which means that neglecting sealing results in rapid decay and expensive replacement costs of $4,125 to $11,650. Sealing your deck is essential for maintaining its durability and protecting your home.

Q: How long does it take for the sealant to dry, and when is it safe to use the deck?

The sealant on your deck dries within a few hours and reaches full cure within 72 hours before regular use. It is essential to wait until the complete curing period to ensure the protective layer fully sets and resists weather and foot traffic. Proper drying guarantees that your deck is fully protected against moisture and environmental damage, ensuring lasting quality.

"We write this review as a sigh of relief now that our renovation project with River View is finally complete. The quality of the final work is excellent, and the construction crew, architect, and county inspector were all great to work with. The original crew we worked with, led by Edwin, were so hardworking, friendly, thorough, and fast. That's what really pushed us from 2 to 3 stars. However, the process getting here was frustrating and unnecessarily chaotic. Timeline & Communication Issues: Initial promise: We were clear that the renovation had to allow us to live in our home during construction and be completed before Christmas. Early communication: Our original project manager, Cris, was personable, and early communication seemed fine, if a bit informal and sometimes inappropriately personal. Major miscommunication: Near the holidays, we discovered that the plans submitted included cutting into the roof — something we explicitly said we didn’t want. This contradicted verbal assurances and caused major last-minute changes. Project Management Failures: Poor planning and oversight: Cris and the architect’s plan didn’t align with the construction work. We had to get involved directly with the county to fix errors. Paperwork errors: Incorrect submissions to the county added delays and confusion, which we had to monitor ourselves. Last-minute scramble: We were cleaning up dust on Christmas Eve due to these planning failures. Personnel Turnover & Lack of Handoff: Cris leaves the company: No proper handover to James, the new PM, who was unfamiliar with our project. Crew replaced: The original crew, who were great, were gone; new crew had no context or direction. James leaves: Another handoff with no context — the third PM had no idea about our project or its outstanding items. Escalation mishandled: When we raised our concerns with Kyle, the CEO, the response felt dismissive, with no accountability for the previous missteps. In summary, it's a beautiful end result... but we’re glad it’s over. The process left us frustrated, confused, and frankly, exhausted."
