"Super impressed with this company! Called less than 10 minutes after completing my request, came out the same day to look at the job, and provided me with a quote by the evening. They were able to fit me in the next day as I needed the job done quickly since my fence had blown down and I have two dogs. The quality of the work was very high and on top of that they were so friendly and professional. I think that the first time I've ever hired a contractor that did exactly what they said, including showing up on time! I will hire this company again and recommend them to anyone needing fence work. Thanks Valenzuela Fence!"

"I can't say enough good things about Jason and his team at Viking Deck & Fence Care. They did an amazing job cleaning and sealing my deck, and the results are better than I ever expected! From the start, Jason was professional, knowledgeable, and incredibly responsive to all my questions. He took the time to explain the process and make sure I was comfortable with everything before starting the job. The deck looks brand newâ Jason's attention to detail was outstanding, and you can really see the care he puts into his work. He worked efficiently without cutting any corners, and the sealing was done perfectly to ensure long-lasting protection. I highly recommend Viking Deck & Fence Care to anyone looking for quality service. Jason's expertise and dedication to his craft truly set him apart!"

"When Martin came to clean my gutters the snow had turned to ice. Instead of rescheduling Martin cleaned out the ice and was able to clear out the gutters and downspouts. Martinâ s commitment to his work was much appreciated."

"Workers showed up on time and kept it great communication. Clean and respectful of property. Marco Construction provided great rates and were a pleasure to work with. When working with Mark and his team, it is best to come to the plate with everything you want to do. They did great working with me on my deck through each board and nail. I would advise you to do your homework and know everything you want done before hand. It will make the process a lot easier on you and them. If I had it over to do again, I would have them replace my whole deck and not piecemill each board. But if you need your deck refurbished or rebuilt, these guys will do well for you at a fair price and you might make a few friends in the process."

FAQs for deck, fence, patio or porch clean and seal projects in Highlands Ranch, CO

You 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.

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.

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.

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.

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.

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.
