"Kyle responded to my request immediately, and communicated well throughout the process. He showed up on time, and was professional, knowledgeable, and efficient. He completed all of my projects - and even came back to my house within minutes, after I texted him about a project I had forgotten! I highly recommend him, and will undoubtedly contact him again in the future."

"Juan and his team are amazing. Juan is very knowledgeable, and was always quick to respond to our questions. He and everyone that worked on our project was extremely kind and respectful of our home. They demoed our old deck and put in a new patio, we couldn’t be happier with the way the process has gone. Highly recommend Bernal Concrete!!"

"Wayne removed old windows and installed new windows in Ft Morgan Co at my folks house in the back patio. He came all the way down to give them an estimate (12 Windows), when other contractors from Ft Morgan just told them to come look at their windows and bring measurements. Wayne is very professional and performed the work with perfection. My folks would like to give him the highest recommendation. Thanks Wayne. Renee"

"Both my husband and I enjoyed working with Luke. He took time to listen to what we wanted and answer questions. He even provided information that helped settle a bit of confusion we had about placement of the fence. He built the fence to be super durable against kids and kept the safety of both our children and pet in mind during the construction. I do plan on using them in the future for further home repair/renovation."

FAQs for deck, fence, patio or porch clean and seal projects in Longmont, 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.
