"Can't say enough about OCR! Our roof looks great and our experience with this company was wonderful! Jake knows his stuff and his crew finished the job in two and a half days. They cleaned up at the end of each day and when the job was finished we had quality shingles and they cleaned up so well you couldn't tell they were here. We also appreciated that OCR, Jake or Jason, was here on the roof with our insurance claims guy, that right there really made a difference. Would recommend this company to anyone!"

"Hired Jarrett to replace our old, worn out front entry door with a new one we recently purchased. The communication was great, as he came by to give us an estimate and we decided to schedule the work. He called the night before to confirm and arrived on time the next morning and got right to work. Even though it was a challenge, as our house has settled considerably, he handled it skillfully, made sure everything was good, cleaned up well and got the job completed, as promised. Would not hesitate to call him again, in the future, for more projects. A very positive experience. A++"

"I normally dont leave reviews, good or bad, but the quality of work done in such a timely manner with Tri State is worth the time. The gentleman that gave us the quote went above and beyond to make sure we were educated, the installers were very fast and professional, I couldn't have asked for anything more honestly. I sent my neighbor their way, and they did the same for them. Would definitely hire again and recommend to anyone needing gutter work done!"

"Gil does excellent work!! He power sprayed and painted (with a sealing paint) the metal roof on our storage building. He replaced some damaged deck boards, power sprayed the entire deck and then painted the entire deck with a paint sealer. He also replaced a strip of wood above a transom window and painted. Gil also installed (2) grab handles in the bathroom area. We were so happy with the results of the completed projects. He also explained the procedures for the projects and the costs. Very easy to work with and honest."

FAQs for deck, fence, patio or porch clean and seal projects in Diamond, MO

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.
