"Contractor provided a free estimate. He scheduled the work and started on time. Contractor scraped old paint, caulked and replaced rotted wood before painting. Contractor also replaced screens on back porch. Contractor showed up on time, answered all questions happily and left area sparking clean each day before leaving. The painting job was fantastic. I am very pleased and would enthusiastically recommend this company."

"Needed to have my deck stained. They provided a reasonable price. They cleaned and sanded deck. I?m glad they educated me on the oil stain. The oil stain, Ready Seal, looks great. The man who stained the deck did an outstanding job. He was very detailed in ensuring the stain was evenly spread. Great Job Leonpro!"

"Jimmy Castillo and William Rojas did an outstanding job. I like that they took the time to do things right and letting me know when something was previously installed wrong, i.e. bathroom vanity not attached to the wall. This is the third project JW has done for me and every time the outcome was what I expected or better. I love that they clean as they go!!! You expect having to clean up after a project, but they always cover things up, put down floor protection, and constantly clean/vacuum. I was shocked to see Jimmy on his hands and knees cleaning my patio when they were done, one less project this spring for me!! Thanks guys."

FAQs for deck, fence, patio or porch clean and seal projects in Ellicott City, MD

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.
