Concrete Cleaning
Concrete & Flatwork Cleaning in Kirkland, WA
Pressure washing for the flat surfaces around your property, including concrete, pavers, limestone, and composite, with the pressure matched to each surface.
Service Overview
Flatwork means the horizontal surfaces around a property. The driveway you park on, the walkway to the front door, the patio out back, and the paver or composite areas in between.
Those surfaces take the most foot traffic, the most rain, and often the most shade, which is why they usually discolor before anything else does. Around here the buildup is rarely just dirt. Moss, mildew, and algae take hold through the wet months and spread across concrete and paver joints.
It happens slowly, so most homeowners do not notice until the flatwork no longer matches the rest of the property. We clean these surfaces using surface cleaning equipment along with wand work for edges and detail areas, so the finish comes out even instead of striped.

When Flatwork Cleaning Makes Sense
Common reasons homeowners around Kirkland schedule concrete and flatwork cleaning.
Green or Black Discoloration
Moss, algae, and mildew tint concrete green, gray, or black, especially in shaded spots that stay damp.
Slippery Walkways
Growth on a walkway or patio gets slick when it is wet. Clearing it is as much about safety as looks.
Mismatched Surfaces
A freshly washed house next to a stained driveway makes the driveway stand out. Flatwork is often the piece that ties it back together.
Growth in the Joints
Paver joints and control joints collect debris that growth takes root in, and over time that works the surface apart.
Getting Ready to Sell or Host
Clean flatwork is one of the fastest visual improvements before listing photos, an open house, or an event.
Regular Upkeep
Left alone, buildup keeps spreading and holding moisture on the surface. Cleaning it now and then keeps it from turning into a bigger project.

Our Flatwork Cleaning Process
A straightforward three step process, used on every flatwork job.
- 01
Assessment & Protection
We start by assessing drainage and covering storm drains, then take the necessary steps to protect the property before any work begins.
- 02
Treatment
We apply a solution to break down and kill organic staining and buildup like moss, mildew, and algae.
- 03
Cleaning
Next comes thorough surface cleaning and wand work, using the necessary pressure for each surface, followed by a rinse and removal of any sludge or puddled water.
Stains and Specialty Work
There is a difference between general buildup and a specific stain. Moss, mildew, algae, and everyday grime are what a standard flatwork cleaning is for. Things like rust and oil behave differently, so they get handled as specialty work rather than part of a normal wash.
If your driveway or patio has staining beyond general buildup, mention it when you request an estimate so we can look at it properly. We would rather tell you what is realistic than promise a result the surface will not give.
We do not promise that every stain will come out completely. It depends on the surface, the type of staining, and how long it has been there.

Questions
Frequently Asked
Can you remove oil stains from my driveway?+
Oil is handled as specialty work rather than a standard cleaning. How much comes out depends on the stain and the surface, so we look at it before telling you what to expect.
What surfaces does flatwork cleaning cover?+
Flat surfaces like concrete, pavers, limestone, and composite. The pressure we use is matched to the surface being cleaned.
What happens to the dirty water?+
We assess drainage and cover storm drains before we start, and any sludge or puddled water gets removed once the cleaning is done.
Will my driveway look brand new?+
Organic staining like moss, mildew, and algae usually responds well. Deeper staining that has soaked into the surface may lighten rather than disappear, and we will tell you that before we start.
Do I need to be home during the service?+
That can depend on the property and the work being done. We can go over any access details with you before the appointment.
