At St. Johns Wash and Seal, we provide professional deck and dock washing, sanding, sealing, and surface restoration for homeowners throughout St. Johns County, Florida.
Many homes in the area feature outdoor structures like decks, docks, gazebos, seating areas, and built-in features made from wood or composite materials. Florida’s sun, moisture, and water exposure can wear these surfaces down quickly. Our services are designed to clean, protect, and restore them so they stay safe, functional, and enjoyable.
Decks and docks in St. Johns County are exposed to:
Constant moisture and humidity
Direct sun and UV damage
Mold, algae, and mildew growth
Foot traffic, furniture wear, and water exposure
Without regular care, surfaces can fade, stain, splinter, or become slippery. Routine maintenance helps extend the life of both residential decks and waterfront docks.
Our washing services safely remove dirt, algae, mildew, and surface buildup from decks and docks.
Deck and dock washing helps:
Restore appearance and color
Improve traction and safety

Our sanding and preparation services focus on:

Most decks and docks benefit from annual cleaning, with sealing every 1–3 years depending on exposure and material.
This is a great family-run business. We had to replace and re-stain some damaged boards on our deck. Frank and Jim were very patient in providing us with various options, and transparent on cost impacts of materials. The workmanship was great and the entire process was professionally handled. This would be my go-to for future deck washing/sealing work.
We had a great experience working with Frank and Jim and the entire team that refinished our outdoor deck. They were responsive, efficient, and reasonably priced. Would work with them again!
They did an incredible job cleaning the 20 year old+ roof for our home that we just bought. We were very nervous about this job but the team was reassuring and did an amazing job! The roof had moss growing on it and they were very gentle with the cleaning. The roof looks brand new now and will probably give us a few more years of life now. The team also cleaned up around the property well. We were very pleased.
I had a great experience with Westchester Wash and Seal. Frank was very communicative and responsive, and the guys were meticulous with the work and keeping the surrounding areas clean. They soft washed my roof, refinished a deck, and power washed some outdoor furniture, and everything looks brand new. They missed a small section of moss on the roof and were back within a day to take care of it. Very impressive all around, and I’ll definitely be using them in the future.
Great communication and service. Would highly recommend to anyone looking to have their deck, porch, or patio cleaned.
Just had many exterior areas, roof, windows, swing set, and furniture treated. The results were amazing, the staff was incredible, just an overall top notch experience. Highly recommend using this company.
