"This was money well spent. Our roof is light gray and black streaks as well as moss were highly visible from the ground, detracting from the overall appearance of our house. Moreover the mildew reduces the life of the roof. Now it looks like new again. Thiago is thorough, professional and responsible."

"I recently contracted Victor to do a couple projects on my home and was very pleased with his work. I first needed roof cleaning services to remove some algae and stains that had built up on shaded and northerly exposed areas of my roof. Victor worked carefully and meticulously to fully clean the roof and restore it to good condition. I also needed repairs to the roof fascia and a section of aluminum siding that had been damaged by a fallen tree branch. Other contractors I spoke with claimed that I couldn’t repair just a section of the siding and would need to replace the entire wall to avoid a mismatch of old and new colors. However, Victor was able to remove the damaged section of siding, replace it with a new section and then paint the new siding with an exact match in paint color so that it was impossible to tell where the damage had been. I was very happy with the quality of Victor’s work and his willingness to figure out a way of inexpensively replacing and painting over the damaged parts of my siding. l would definitely recommend his services."

"I can't say enough positive things about my experience with Phoenix. If you're looking for a quality fence at a reasonable price look no further. Jeff and Karen were incredible to work with. We had 5 different companies come out for quotes and Jeff's thorough, no-nonsense explanation of fence types and prices made it an easy choice. When we decided to switch a portion of the fence from picket to picket w/ cap-board, I called Karen expecting the quote to be more expensive but she and Jeff said they could do it for the same price. Despite being told it was a two week wait, I got a call from Karen that they could install it the same week. Both Jeff and Karen are extremely professional and their communication made the project a stress-free, enjoyable experience. The workers, who were all brothers, were incredible. I was shocked by the speed with which they tore down the old chainlink fence, which was installed 60 years ago and had literally grown through the trunk of two trees. They methodically installed the new 218 square foot fence in one day, making sure everything was done properly. When the job was done, one worker insisted on grabbing a tool and coming back an hour later to remove a very stubborn old fence post. This level of detail and craftsmanship is hard to find nowadays. The fence has transformed our backyard and we couldn't be more happy!"

"I wish everyone did business like these guys. The whole process was 100% online, from requesting the quote to paying for the service. They even did the house wash when I wasn’t home, so no need to take off work or schedule a time “window”. I’ve previously hired these guys to pressure wash my driveway and they did an excellent job on that, too. Definitely recommend and I will be a repeat customer for sure."

"We hired them for a full house wash and couldn’t be happier with the results. They arrived on time, were very careful with our property, and removed years of dirt and mildew. Our home looks fresh and clean again. Excellent service and fair pricing!"

"My wife and I had a great experience with Lomar Painting, Bismarck, the owner, and the entire painting team. The written proposal was detailed, easy to understand and did not change with the exception of additional work we added during the painting process. The team of painters arrived at the start of the business day and stayed for at least 8 hours. The job site was always cleaned at the end of the day. I would use Lomar Painting again and have already recommended them to my neighbors."

"I hired Millenium USA Painting to repaint my master bedroom. First let me say that this was no simple paint job. There was paint peeling from the walls, and parts of the walls were pockmarked because of patches literally falling off. I intended to have the room repainted years ago, but the Covid epidemic forced me to put it on hiatus, which of course allowed the problem to get even worse. When I contacted Millenium, Marco got back to me immediately to do an estimate. When I said that I was hoping to get the job done soon, he managed to schedule it within a week. The professionalism of his crew was very impressive: they showed up very early in the morning and worked into the evening on both days, so that they could finish the job by the promised deadline. And the final result was magnificent. The room is unrecognizable (in a good way) because the sanding, refinishing, and painting completely restored it. I highly recommend this company."

"I used this company for a number of years and the overall service is no longer the same. I had them over to clean my gutters and I witnessed ladders slamming against the side of my house and they tore one of the edges from the corner of my roof with their step ladder. I will not use them going forward."

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