"The work performed was outstanding. Cornerstone Hydro Wash was professional, knowledgeable & clearly experienced. I was looking for more expertise than a lawn company that had a pressure washer. Pressure washing, among other things, IS their business, and they had the equipment, chemicals, knowledge & a truckload of commercial equipment to get the job done right. Not only did I get my deck & my whole house washed, but Brian amazingly transformed my driveway, sidewalk & porch. They are reasonably priced - worth every dollar. I highly recommend them..."

"Alexander and his team are outstanding! They brought my old sad deck back to life and I love it! It totally transformed by back yard. Alexander took the time to work with me on choosing and matching the stain color and that was a process and he was so accommodating and patient. The team worked hard to prepare the deck before staining by installing new handrails, securing planks, sanding, and moving my furniture. He even fixed my gate which was not installed properly. I can not say enough about how beyond thrilled I am with their work, professionalism, and ease of working with them. I am looking forward to working with Alexander on my next project."

"I built the home Mr William Smith was contracted to replace the screening of the gazebo on my home’s deck and then power wash both the gazebo and deck. Do working with contractors is not new to me. After cleaning he was requested to apply a clear stain of my choice inside the gazebo and then a solid stain of my choice to both the deck surface and the gazebo’ outsides. I could not have been happier with a contractor ‘s service performance. Weather cooperating he masterfully completed everything in 3 days as estimated. The screening replacement was not straight forwarded. It not just that Mr Smith and his support did a great job he did not require deposit or payment on this scale of job until it was completed and performance approved by me. He is as open and honest of a contractor as I have met. His attention to detail was as if it was his own property. Also his cleanup was excellent. I thought his price was fair and have already recommended his services to neighbors."

"Immediate quote, timely service, and good follow up. I will be using J&W for a few additional projects as well. The work on our porch to re point bricks and put in railings was immaculate. We are very satisfied with all aspects of working with this contractor."

"I needed to primarily have the garage pressure washed after cutting down a tree in between properties.  There was a great deal of algae growth on the siding.  I contacted the technician and he promptly set up an appointment.  He arrived on time and completed the job quickly.  After I saw the results on the garage, I inquired if he could do the rest of the house and vinyl fencing around my property.  He was extremely accommodating and was able to complete my service request the same day.  I couldn't be happier with the results!  While he was here, he noticed my brick patio and walkway also had a great deal of algae and weeds.  We discussed how slippery the brick becomes when it rains, and the fact that I have to continually weed it.  He made the suggestion of sealing the brick which would prevent the growth of vegetation.  That means I wouldn't have to spend so much time weeding!  I was elated, as this has been a continual problem for me for years!  I have scheduled another service appointment for him to complete this in April.  He was extremely professional and customer service oriented.  I will continue to use this company and would highly recommend him to any of my family, friends, and neighbors."

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