Deck & Fence
Wood and composite brought back from gray and slick to clean and even, ready for the season or for staining if that is next.

Clear the clogs that cause overflow, then scrub the dark stripes off the gutter faces so the whole exterior looks finished.

Why Signature
The difference is in how we work
The right method, not the fastest
We match the pressure and the cleaning solution to each surface, so things get clean without getting damaged.
Bonded and insured
Bonded and fully insured on every job, so the people on your property are covered and so are you.
Safe for plants, pets, and people
We wet down landscaping, use biodegradable solutions, and rinse everything clean when we are done.
The method matters
Why we don't point a pressure washer at everything
High pressure cleans hard surfaces fast. Point it at a roof or siding and it strips, dents, and forces water where it does not belong. The fix for those is soft washing: low pressure plus the right solution that kills algae and mold at the root.
Pressure Washing
1,500–4,000 PSI
High pressure for hard surfaces that can take it: concrete driveways, walkways, patios, and brick. It blasts off oil, gum, tire marks, and ground-in dirt.
Soft Washing
50–150 PSI
Low pressure and a biodegradable solution that kills algae, mold, and mildew at the root. The right call for roofs, siding, stucco, and most decks.

About
Started by a local family. Built on doing it right.
I am John Morais. I started Signature because I could not find a Maryland company that did the basics: show up on time, use the right method for the surface, protect the property, and stand behind the work.
So I built one. We are new, and that means every job has to be earned. I treat your home the way I treat my own, and I am there to make sure it is done right.
- The right method for every surface
- We protect what we can't replace
- You see the price before we start
- We follow up after every job
FAQ
Straight answers
Still have a question? Call (240) 441-8089, email signaturepressurewashingmd@gmail.com, or request a free quote.
How much does it cost?
It depends on the size of the surface and how dirty it is. We give you a clear written price before any work starts, and there are no surprise charges. Send a few details and we will get you a free quote within 24 hours.
Will it damage my siding or roof?
No. We soft wash siding and roofs with low pressure and a cleaning solution, not a high-pressure blast. That is the method shingle and siding makers recommend, and it protects your warranty.
Is it safe for plants and pets?
Yes. We wet down your landscaping before and after, use biodegradable solutions, and rinse everything clean. Keep pets inside while we work and they will be fine.
Do I need to be home?
Not for the whole job. As long as we have access to the areas and an outdoor water spigot, you can go about your day. We will confirm the plan with you first and check in when we are done.
What are the black streaks on my roof?
That is algae, usually a type called Gloeocapsa magma. It feeds on the limestone in your shingles and spreads over time. A soft wash kills it at the root instead of just rinsing the surface.
How long do results last?
A soft wash kills the growth at the root, so results last far longer than a quick rinse. Most homes stay clean for one to three years depending on shade, trees, and moisture.
How often should I wash my home?
For most Maryland homes, once a year keeps siding and concrete looking sharp and stops algae from taking hold. Shaded or wooded lots may want it a little more often.
Are you bonded and insured?
Yes. Signature is bonded and insured. We are glad to share proof before we start, so the people on your property and your home are both covered.
