"I had to have my deck refinished because I had done it myself and really did a bad job:))) Alex responded right away and was able to get in and get the deck stripped and refinished quickly. It really looks great, he did a wonderful job. He was reliable and in great communication about the cost, the likely outcome ( since he had to try to remove my very over applied oil based stain) and about the timing of the work. I would recommend him and I will use him again for any deck or painting needs I have!! excellent!"

"I had a great experience with Sean, Christian and Melissa🙏. They did not try to upsell me by replacing the whole deck, instead they worked very hard to sand the highly weathered deck and repair it. I am thankful for the work they did at a very reasonable cost. I am very happy with the end results."

"I had a water leak around a window. Jorge promptly came and inspected it as well as all my windows. He took pictures of what he found. Very little caulking around the windows and there were gaps in it. He showed me the pictures and we discussed the work that needed done. With the Fall rain season upon us, he was able to quickly schedule the work. I really appreciated this. Once he completed the work, he took me around and showed me what he did. It looks much better than the previous caulking! I recommend Jorge for his attention to detail and efficiency. I am going to keep in him in mind for any future needs and definitely call him."

"We are very happy with how Serge was able to go through our list of home maintenance projects, and complete them all in less than 2 days. He repaired cracked plaster on walls, and repainted them; installed cabinet handles; fixed a short in a light switch; fixed a toilet; and re-grouted the tile in a shower. He was dependable, arriving on schedule, and easy to contact and communicate with. When we needed him to come back to retouch a small chip in the grout, he set up an appointment and prompting took care of it. He also provided an itemized list of costs soon after he visited our home to see what was needed to be done. We will be hiring him for future projects and highly recommend him to others."

"Chris showed up early and had a great attitude during the entire process. He needed to assemble a TV stand for us. When we received the package it was in terrible condition from the shipper and we were suspect to even begin to assemble it because of our initial visual concerns. But Chris did a great job of assembly and for the pieces that were defective and pieces that had been abused or pre used, he was able to work with each piece to design it to work. Chris went well beyond our expectations as he did more than just a symbol, he also retrofitted defective parts so that we could have a unit that would halfway work for us."

"Hired THT to clean my Mother's roof and the roof of a small shed on the property. He arrived when they said he would, worked diligently and did a great job on the roofs as well as the cleanup. Second time I've used this company, pleased both times."

"I could not be more pleased with Joseph and the work he performed. I needed an existing patio to be replaced due to tree roots which impacted drainage towards the house foundation. After 5 bids, I decided to go with Joseph due to his competitive bid and demonstrated expertise. He and his team were stellar, solid communication, friendly, and took the time to explain to me the leveling/answering all my questions. In 3 short days the project was completed and it looks great. I would highly recommend Joseph to anyone looking for concrete work."

"Overall the workers did a fabulous job. There was so much foliage to cut back. I was concerned about the general vagueness of the contract though and tried to get the details confirmed with Mike (the supervisor) before signing. This was a difficult process, but since pictures were taken before the bid, and Mike seemed confident with what needed to be done, I thought it was a good deal. By the time all of this had been handled, a couple of weeks had passed so I called the office to confirm that the contract would still be honored before signing. Throughout this whole ordeal my attempts to set up regular maintenance service were not acknowledged. As I said the men did a great job with the overall clean-up, but there were specific items on the contract that were not done. Having paid half of the amount before the work started, I let them know that I would be happy to pay the other half when all of the work listed on the contract had been completed. A week and a half later Mike called to inspect my yard. The young man with him took care of the neglected cuttings. Mike followed me to the backyard where a short walk-way was to be made with bricks we had at home. This is when he said he had lost money on this job. When we began to discuss why the walkway was not done, he made many excuses that I corrected. He claimed the existing concrete walkways along the side of the house were not there before and that was what it referred to. He then claimed that cleaning those existing walkaways was what it meant. Next, that the people typing his notes must have misread them. Next he claimed he had forgotten that it needed to be done. Afterwards he took excessive amounts of time just staring at the ground where the path was to be laid without saying anything to me. I had the typed contract in my hand which stated the exact height and width of the path. I kept showing him the area where the contract referred and explaining why it was chosen in order to jog his memory. He began to say he sort of remembered. When I told him that I was not pleased that this was not done, he whipped his head to me seemingly shocked. More nonsense and hem-hawing occurred. Eventually I said I didn't want his workers to do the job. I turned to the house to leave, paid compliments to his workers, and as he was turning around the corner of my house, he offered to take $200 off the total for the path not being built. To end my review, I would like to add that in all the time that Mike was at my house, not once did he apologize for anything. I will never use them again and never recommend them to my friends."

"Everything went very well. We had different pieces of our job which divided up well around the Memorial Day weekend. Painters were punctual, polite, professional and cleaned up everything. For the exterior, there was considerable work to pressure wash, scrape, prime, and then paint. The new paint looks beautiful and we are very pleased."

FAQs for deck, fence, patio or porch clean and seal projects in Black Diamond, WA

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.
