"Deckmaster provided a free estimate for carpentry repair work on my wooden deck and fence, and also for a powerwash and reseal of the deck, deck stairs, and a fence. I contracted them to do the carpentry only (the powerwash/sealing was more than double the cost I normally pay). Scheduling was done within a week or so, and I was very pleased with the work Gustavo and his assistant did. The repair was done carefully and competently, and showed good attention to detail. I would definitely call Deckmaster again if I needed any repair work done."

"Kurt was easy to reach via email or telephone. Apprised us of his approach to stripping our deck of its horrible paint coating and was upfront of the general cost during his first visit. He did need to be reminded to provide a specific contract upfront. Otherwise, deck restoration work progressed quickly once weather conditions permitted start and Kurt finished the large project within a few days."

"Doug replaced a 30 year old deck support post and did an excellent job. He had to 'problem-solve' some prior construction issues which demonstrated his excellent carpentry skills. I will certainly use Doug in future projects around our home!"

"Exceptional work! I hired FAMB Construction, LLC after interviewing quite a contractors (large and small companies) to replace my wood deck with Trex composite decking. Noel and Claudia are extremely professional from start to finish of the project and clearly communicated in detail what work was going to be done. Noel provided a variety of actual samples choose from and provided helpful details on how the project would be completed. My deck looks amazing and Noel even corrected some deck issues that were not within the scope of the project. I would highly recommend FAMB Construction for their high level craftmanship, professionalism, timeliness, and cost efficiency in completing my project. Truly a Five Star ***** contractor, no exaggeration."

"I would highly recommend Ed. He came out the same day he contacted us about power washing and sealing our deck. He explained what he would do and told us the product he would use. The price was fair. He came the next day and the job was completed. This was the best experience we have ever had working with a contractor."

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