Frequently Asked Questions
Why is my composite deck slippery or discolored?
Algae, mold, and mildew often build up on shaded or damp areas. These can make the deck slick and cause discoloration if not properly cleaned.
Can power washing damage composite decking?
Yes. High-pressure washing can cause surface etching or remove protective coatings. Soft washing gently lifts contaminants without abrasion.
What’s the best way to clean Trex or other composite brands?
Our proprietary soft washing solution is safe for all major composite brands like Trex, TimberTech, and Fiberon, and delivers deeper, longer-lasting clean.
How often should a composite deck be cleaned?
We recommend professional cleaning every 1–2 years, depending on exposure to shade, moisture, and foot traffic.

Quality, Professionalism
These guys are great, their service far exceeding my expectations and that doesn't happen very often. They were very professional and paid great attention to detail, the house looks amazing! I also feel like they used a lot less water than a typical power washing service which was very nice and the house is super clean again. Moreover, they use less pressure so the water didn't peel off any paint or impact the surface of our cement like other services would. Window sills were nice and clean too! Softwash Platoon is great and I would recommend them to anyone!

Softwash crew did an outstanding job at our house! Seriously good work, both in the front door area (floor tiles, ceiling, walls), as well as our upper and lower patios in the back of house. The patios were large areas and badly stained with dirt and algae. All areas are now gleaming! We highly recommend this company. Their wonderful work made a significant difference.

After our insurance company did a surprise exterior inspection they requested we have our roof cleaned of the moss/mildew. We hired SoftWash Platoon and they did a fantastic job!! Our roof looks new (our neighbor said they would eat their dinner off it because it looked so clean)! The team, especially Jose, was very polite and went above and beyond to make sure the job was done right. Donna, who scheduled our appointment, was also wonderful to work with, ensuring that the job was completed prior to the deadline set by our insurance company. Though the pricing was a little more than what we wanted to spend, the work came with a 5 year warranty, so if the moss comes back we will certainly take them up on that and have our roof cleaned again. Excited to maximize our roof life and highly recommend this team and their services.

Professionalism
Had a great experience with this company on a softwash of our roof and nearly 100 year old stone and stucco house. Owner and technicians were all extremely courteous and knowledgeable. They went out of their way to ensure our plants didn’t get damaged, relocated some hanging baskets that I missed, and set everything back up again afterwards. House looks great. Our brick patio and concrete walkways look better than ever - we had them power washed in the past and this worked better.

We had Softwash Platoon clean the entire exterior of our 1870’s white wood siding house that definitely needed cleaning. From the first meeting and estimate with Chris, to the scheduling with Donna and the cleaning by José and Herbert, we could not be more impressed. Communication was excellent and the work on the house was thorough and done with real care. Prior to starting, José explained the process and what we could expect. It was a scorching hot day and the guys worked hard and cleaned every surface thoroughly. After completing their work, they walked us around to show us what had been done. The outcome is a sparkling clean house and roof that has never looked better. We would definitely recommend this service. Thank you to the whole team. You exceeded our expectations. Anne
