"The Renew Team did a great job with replacing a new deck for me. They were efficient, professional, left no mess for me to clean up. They put a wooden fence in for me a couple of years ago and did such a nice job I wanted them to replace my large deck. Would definitely recommend Renew!"

"They did a beautiful job and were conscientious about their work. They saw an issue with an additional rotted wood tree that should be chopped down to avoid future problems. They explained the issue to me and I gave them permission to go ahead and chop it down to avoid future problems. I would recommend this company for this work."

"Dave and his crew were fantastic! I ordered the wrong color by mistake! Dave and I went to the Sherwin Williams paint store. They were unable to tweak my bad paint to match the bracket from the door so I ended up buying a new gallon that matched it perfectly! With Dave's contractor discount I did save money on the new paint. He was so helpful and cooperative! They did a great job on the door and trim. Looks brand new! I would highly recommend Dave for any painting project!"

"Randy was just awesome! He was very knowledgeable and very kind. I called him around 10 am after having a new refrigerator delivered. I explained that I needed some help with the water line that connects to the ice maker/water dispenser. He explained over the phone what likely needed to happen and then told me that he would get back with me in a couple of hours. I gave him my address and info and sure enough--2 hours later he comes, takes a look at what I need done, went to the hardware store, and bought what was needed. He then came back and installed everything and spent a good deal of time talking to me about installing our gutters. He's very friendly and I would not hesitate to call him again if we need work done on our house or remodeling. The quality of service we received definitely exceeded the price we paid to hire him. Randy, if you see this, thanks again very much for all of your help today!"

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