"Excellent. My deck looks brand new. I did not think the deck would come out looking like I just had it installed. I am very happy with the results. Rich gave me a fair price and got the job done in a timely fashion. Thanks Rich. I will surely call on you in the future."

"We bought a new cedar fence which needed to be power washed and sealed. The power washing went fine. The sealing we had some issues and had to call them back a few times. The job looks like they were not skilled at this. I think the job was rushed because details were not paid attention to. On a good note, the owner was responsive and friendly."

"Hired to power wash and stain ~20year old Ipe deck. Did a very good job at a good price. Fred was very communicative throughout the process. We may have made a bad call with respect to picking dates to complete work, based on temperature and rain, but that is as much on us as Fred. There is a lot of variation in the coloration of boards so we'll see in time. I'd definitely consider him for future projects."

"This is the 2nd time I've used Freeborne and I would definitely have them back again. They built a 12' X 16' enclosed room on a 2nd story deck and it came out great. Lenny, Scott and crew knew what we wanted and exceeded our expectations without over complicating the project. There were no budget surprises either. The amount we discussed at the beginning was what we were charged. If I could I would use them to do projects inside of the house!"

"I engaged Landis Painting to paint the exterior of my house/garage --and to clean/solid stain my large double deck--because of the excellent exterior paint job they did for me before (which lasted 12 years!). His experienced staff was the exact same crew that painted my house years before—not short time employees. Steve is very meticulous about the paint products he uses and how they are applied, consulting with the manufacturers when needed. Knowing my concern about choosing exterior colors (an expensive choice to get wrong), he recommended an excellent color consultant, who was worth every penny. Steve’s crew was punctual, efficient, and meticulous in sanding, patching, priming and painting my home. When Steve determined that my deck’s original solid stain product was no longer available on the market, he identified the correct alternative product and had it perfectly matched to my deck’s existing color (he went to two paint stores before getting a match to his satisfaction). Steve cares about getting things right and about long durability of the paint products he uses. Happy to answer all my questions about the how and why. (He even did some extra touchups not included in my job quote.) In short, I knew that hiring Landis Painting again was a no-brainer and highly recommend Steve and his team to anyone wanting a professional result."

FAQs for deck, fence, patio or porch clean and seal projects in Raritan, NJ

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.
