Customers say: Quality work

"Absolutely wonderful! Daler arrived early and started work immediately, removing the old air conditioner and installing the new one with conscientious attention to detail and great care to do so without damaging the window frame. His young daughter Robia was also there, handing Daler the correct tools and paying close attention to his work; she is already a top-notch assistant to her Dad! The AC is now securely installed and Daler also took the time to install weather-stripping when he noticed that our window frame was just a tiny bit uneven. Both Daler and Robia were courteous, caring, and truly professional. We would be delighted to hire D & R Repair for future projects!"

"We recently bought a lakehouse with at least 10 years of moss, lichen and bacteria growing on the rooftops. On parts of the roof, the moss was over an inch thick. We needed to clean the roof in order to get insurance. I found Barb and her team when I was out for a run and they were cleaning another house around the same lake. I didn't have my phone, but I gave the worker my contact info in hopes they would call back. A couple of days later, before I remembered to look them up, Barb called me back to get the address of the house so she could take a look and get us an estimate. She took a ton of pictures from both the ground level and on top of the house to get a full look and gave me an honest assessment, which was no surprise to us how bad it was. Then she explained the entire cleaning process in full detail, including the organic soap/detergent her teams used and the cleaning machines. They were not just a bunch of power-washers using bleach and other chemicals (like another company we had called); they had special machines that protected the roofing materials and detergents that wouldn't hurt my kids or the lake itself when all was said and done. With two young kids, I can't stress how important this was to my family. Barb and her crew came out and in one day, they cleaned the roof on the house to pristine condition, and cleaned the cedar roof of the covered patio too (although that was much tougher given the age of those shingles). She also did all the walkways, pavers, and stone columns of the back deck, and sealed everything at the end to protect the roofs for at least another year or two. Even our neighbors across the pond called it "squeaky clean and pristine" from their view. To be honest, they weren't the cheapest but they were worth every penny considering the cleaning job they did and how they did it, and yes, they cleaned up everything when they left and left no trace. I would absolutely recommend them and will use them again."

"This review is long overdue. I contacted Sealpro Mahwah because I have seen their work in several driveways in the neighborhood. I can literally see why they are recommended. Their work looked very good on every driveway that i saw. I contacted the business and response time was very good. I spoke w Lou and he was upfront, honest and very nice. We discussed work that needed to be done- sealcoating and crack fills. We were able to negotiate the quote. I admit the quote was not the lowest of the three bids I received from companies BUT Lou seemed the most upfront of what we could expect. I was comfortable on price we landed on and very happy I went with SealPro. I have recommended to my neighbors and would use them again. Thank you to Lou, his crew and everybody at SealPro."

"Makensy spent a significant amount of time on the phone consulting me on a challenging deck restoration job. He knew his company was unable to complete the job, but did not hesitate to share his knowledge of products to use and steps to take to fix the damage. He sincerely cared about the outcome of our deck knowing he would not make any financial gain from his time and effort. His advice was priceless and guided us in the right direction, saving us hours of needless work and expense. We are so grateful that people like Makensy exist, and will be sure to recommend his company and use him for future jobs."

"We used Gentle Giant to soft wash our home and patio. They did a tremendous job!! the house looks great and the patio looks like new! Habari and his crew were on time, courteous and professional. They moved all of out patio and porch furniture to protect it and they even moved my flowers and planters in the front of the house so they would not get damaged. In addition they cleaned our foundation which was not part of the original estimate at no extra charge. I would use Habari again in a heartbeat and I would recommend him to anyone who is looking for power wash or soft wash services."

FAQs for deck, fence, patio or porch clean and seal projects in Manhattan, NY

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.
