"I recently had the pleasure of hiring PurePower Wash and it was an outstanding experience from start to finish. From the moment I contacted them for a quote, the customer service was top notch. They were friendly, professional and responsive, answering all my questions. On the scheduled day, the technicians arrived on time, equipped with the latest state of the art power wash equipment. Throughout the process, I was impressed with their attention to detail and their commitment to delivering the best results. I also appreciated the safety measures. They made sure all windows, outdoor furniture and plants were protected during the power wash. Not only did they do an outstanding job, they also finished within the estimated time, which was impressive given the size of the job. I highly recommend PurePower Wash for anyone in need of reliable and high quality power wash services. They exceeded my expectations and I will definitely be using their services in the future. Five stars all the way!"

"Needed my deck sealed after a year of curing. Quote was high, but I decided it was worth it. Lots of positive reviews. Had some water marks from pots on the deck. After the first brightening there were still watermarks. I sent Bruce pictures and asked that the guys coming to seal make sure the watermarks were taken care of. He told me to point out the spots and they would take care of it. When the sealers came, I pointed out the marks and asked that they make sure they were taken care of before the sealing. They told me that the water marks were the result of leaving pots on the deck...duh. Obviously this is what happened, but was why I was paying Cal Preserving to take care of it. I don't appreciate having to convince my contractors I want something done the right way. I ended up calling Bruce and explaining that I felt like this was being done in a rush, but he assured me his team was professional and that it would get done properly. Placated, I decided to trust it would be OK, despite the static. That was my first mistake. After they were done sealing they asked for the check (before it had a chance to dry and for me to inspect the work). I told Bruce I didn't feel comfortable with this (over the phone), but he reassured me that they weren't that kind of company and any mistakes or issues would be taken care of. I gave the sealers the check. Mistake number 2. The next day I inspected the work to find huge sections of the hand rail completely unsealed and with power-washer damage. Also the water marks were still there and now sealed in. I took pictures and sent them to Bruce. He came out and we discussed the issues. He was nice and told me not to worry and that his guys would take care of it. Another iteration and the handrail was fixed, but the watermarks are still there. At this point I feel like I didn't get the full value of what I paid, and the hassle I went through to get to where I am now, which is barely passable should be avoided by others so I am writing this review. I don't mind paying premium prices, but when I do, I expect premium work. And if I find something wrong with the work, I expect it to be fixed without contention. The fact is I feel like the job was rushed, and I was pressured into paying early. I am a relatively new homeowner and this whole experience has just been a lesson learned. If the watermarks were taken care of, and the rail done right the first time, and nobody gave me static, I would be rating Cal Preserving with five stars. Take warning!"

"They came a little early and started promptly. Workers were friendly yet polite, easy to have around, minded any water spillage on the sills, kept track of their rags, tools, etc. and the windows & screens looked great. At the end suggested very kindly R&D's other services which I'll be sure to take advantage of next time I need gutters done, solar panels cleaned and exteriors pressure washed. Very good experience!"

"It is hard to find contractors to do various smaller jobs, but Danilo and his team took our projects and completed them very professionally. We had them do a patio brickwork repair project, powerwash and seal the patio, replace a fence gate, paint the exterior eves and facias and install leaf guards on the gutters. All work was performed to my satisfaction in a timely manner. I will have them back in the future for other projects."

"Bayron did a great job patching and repainting the exterior of my house. It wasn't easy because of all the foliage, but he worked around that and it turned out better than I could have hoped. Based on that experience, I hired Bayron to replace my backyard fence. He provided various options and we decided on horizontal slats of smooth redwood. It turned out beautifully, and I keep getting compliments from neighbors. Bayron's easy to work with and takes pride in everything he does -- I highly recommend him!"

"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

FAQs for powerwashing projects in Atherton, CA

Different fence materials require specific pressure levels for safe, effective cleaning. Softwood fences need gentle treatment at 500 PSI maximum, while more durable materials like vinyl and steel can withstand up to 2,000 PSI. Wrought iron fences tolerate the highest pressure at approximately 2,300 PSI. Always begin with the lowest effective setting and maintain appropriate distance from the surface to prevent damage, gradually adjusting as needed based on cleaning results and material response.

The primary distinction between pressure washing and power washing lies in water temperature. Standard pressure washing equipment uses ambient temperature water, while power washing incorporates heated water for enhanced cleaning capability. The heat component makes power washing particularly effective for stubborn stains and organic growth, but it costs more than conventional pressure washing. For routine fence maintenance, standard pressure washing provides sufficient cleaning power without the additional expense.

The decision between professional service and DIY fence cleaning depends on several factors, including equipment access, technical knowledge, and fence characteristics. Equipment rental costs between $40 and $90 daily, making DIY viable for smaller projects. However, professionals bring expertise in appropriate pressure settings, efficient techniques, and proper cleaning solutions. For delicate materials like softwood or ornate fence designs, professional service significantly reduces the risk of damage while ensuring thorough cleaning results.

The duration of a fence pressure washing project varies based on multiple factors, including fence size, material, condition, and accessibility. A standard residential fence cleaning requires several hours to complete, with preparation, cleaning, and cleanup all factored into the timeline. Heavily soiled surfaces, intricate designs, or limited access points may extend the project duration. When planning your schedule, allow sufficient time for the fence to dry completely before applying any treatments or sealants.
