St. Johns Wash and Seal is a locally owned and operated exterior cleaning and sealing company serving homeowners throughout St. Johns County.
We take pride in our craft—and that pride shows up not just in the quality of our work, but in how we treat our customers, their homes, and their time. From the first evaluation to the final walkthrough, our focus is on doing the job right, communicating clearly, and delivering results that last.
We’re proud to be a family-owned, locally managed business, and the Florida flagship location of the Wash and Seal brand. While we benefit from the experience, standards, and best practices of a growing organization, every Wash and Seal location—including ours—operates independently with local ownership, local crews, and deep ties to the communities we serve.
That means when you work with us, you’re not dealing with a franchise or an out-of-town crew—you’re working with professionals who understand Florida homes and care about their reputation here.
We are committed to operating responsibly and efficiently. Whenever possible, we use environmentally conscious products and methods that are effective without being harsh, and we’re always looking for ways to improve how we reduce waste and protect surrounding landscaping and outdoor spaces.
Responsible exterior care is better for your home—and for the community we live in.
Homes in St. Johns County face unique challenges: heat, humidity, mold, algae, salt air, and constant UV exposure. Generic pressure washing can cause damage when the wrong methods are used on tile roofs, stucco, pavers, or finished concrete.
Our services are designed specifically for Florida conditions and include:
Power washing and soft washing using surface-appropriate methods
Roof washing for clay tile and shingle roofs
Paver and patio cleaning, polymeric sand, and sealing
Driveway, concrete, stone, and hardscape cleaning and repair
Deck washing, sanding, and sealing
Exterior stucco and masonry surface repairs
Window washing, gutter cleaning, and specialty exterior services
Homeowners across St. Johns County choose us because of how we work, not just what we offer.
Locally owned and community-focused
Family-run, professionally managed
Florida-appropriate methods—never one-size-fits-all pressure
Honest evaluations and clear recommendations
Respect for your home, property, and schedule
Residential-focused service, with commercial capability
Routine exterior maintenance provides real, measurable value:
Helps prevent surface damage and premature wear
Removes mold, algae, and pollutants that affect air quality
Restores curb appeal quickly and safely
Protects exterior materials from moisture and UV exposure
Supports long-term property value
While exterior cleaning and sealing are at the core of what we do, we also offer select interior and finishing services for homeowners looking for a trusted, all-in-one home care partner. These include interior and exterior painting, interior floor and finish work, and related residential services.
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.
