"We have had them at the house 3 separate times now and they have done a great job every time. We are updating a 15 year old Million+ dollar house and their repair jobs make it look like the original Sheetrock has never been touched. Professional, reliable scheduling, and they clean up after the job is complete."

"He was prompt, did everything I asked and even went the extra mile for me! He cleaned up everything and even gave me information on how to kill this beast! I really appreciate Jon and highly recommend him! I know this was bigger than he imagined and it took a toll on his chainsaw, but he didn't quit until the job was done! I'm a very happy and satisfied customer for life! Thank you Jon!!!"

"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!!"

"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."

"The project was to clean and stain our deck, and we asked him to put stain on a small patio as well. Also, I asked if he could complete it on short notice. Mike worked it into his schedule, and in the end, the deck looks great. The patio is not Mike's specialty, and it turned out okay. In the end, we plan to hire Mike to clean our fence later this fall. When it comes to wood, Mike does a great job, and I would recommend him. Regarding the value, I'm not an expert in this space, but the cost seemed a little high for what we received."

"The gentleman who came were very professional and did everything they could to do the job correctly. Order some extra fencing and we found that Home Depot sent the wrong fencing and the workers went to Home Depot and got the correct fencing. I’d recommend this company to anyone who wants the work done correctly and in a timely manner. Again thank you guys for the great service. "

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.
