"FANTASTIC! My siding is sooo clean. Exterior stairwell was filthy and now great! My garage door and composite deck look brand new! They even cleaned my sidewalks too! We're getting ready to sell our house. I'll call them for our next one! Absolutely!"

"Mike came out prompty to look at the damaged siding. Came out a second time to show me color samples for the replacement siding. Told me when the siding would be received and came out today and did the work. He and his helper cleaned up after the work was done. They did an excellant job of fixing the siding. He had given me a very reasonable estimate. I have asked him for an estimate to replace the roof and will have him do the work. Very professionable and friendly. I will recommend him to friends and family for any work they might need done."

"This was our first experience using AllBrite's house washing service and we were very pleased. The sales manager did the assessment and proposal the same week I called in to schedule a quote. The Service team also made it out in the same week. While this turnaround may not be the norm during peak seasons it was still amazing to see the speed of service even in the fall. Everyone was very friendly and professional. The Service team took special care around all of our plants and the house itself. We had the full house done along with a full pressure washing of the chimney so that we could have the brick treated / sealed by another company later. The house looks excellent and we will definitely be using them again in the future as the need arises. We also had Sparkle Brite applied and we are looking forward to seeing how it works over the next couple of years. Our house is located among many large oak trees which create the perfect conditions for mold and mildew."

"I have a rental property that needs lawn mowing. Maria is very professional, and gave me a quote and invoice over email. I am able to pay online, which is very convenient for a rental property. Her crew did a great job with the large yard, and comes every two weeks on schedule. She reaches out to tell me if there are any issues that will delay her crew. It’s been far and away my best experience with a lawn maintenance company."

"These are great guys, they are professional, have a great product, a lot of good options for those looking for deck repair, they are very responsive, and they say they have high price for high quality but their price came in more around the mid-range for me. Overall, it's clear why these guys are rated so highly and I'm sure I'll be using them again in the future. Great work."

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