Pressure Washing

Pressure Washing is a great way to revive fencing, decking, brick, masonry, and concrete for an affordable price. We use top of the line equipment and currently run a 4000 PSI 16 HP pressure washer that can remove the toughest stains. 

Old fencing and decks will show signs of sun fading and water damage over time if the surface is not properly sealed. To fix these issues we use our pressure washer to carefully remove the damaged layers of wood. This reveals a nice clean surface ready for stains or sealers. 

Concrete can be restored to a like new state by pressure washing with high pressure and in some cases using a greaser to assist with heavy stains. The water literally jets its way into the pores of the concrete and lifts out the dirt and contaminates. 

Brick surfaces can be lightly sprayed with diluted muratic acid and rinsed with diluted ammonia and pressurized water. This assists in removing a micro layer of the brick and mortar which can be later sealed. Sealing the surface is the best action you can take to prevent surface staining and it ensures easier cleaning in the future. 

FAQ About Pressure Washing

What surfaces can be cleaned with a pressure washer? 

Just about all surfaces can be cleaned. Steel, concrete, brick, stone, masonry, fencing, decking, trex decking, & even vinyl can by cleaned with the right equipment. Pressure washing is a must for any exterior painting project to ensure a clean surface for material bond. 

I’ve seen surface damages after pressure washing before from other providers. What causes this? 

Pressure washing can cause surface damage if the equipment operator does not know how to properly adjust the machine for the project being cleaned. We have seen 99% of surface damage caused by a operator who uses too much pressure with too small of a tip or “rotating tips”. Rotary tips will always cause damage on any wood surface leaving “swirl” marks or “lines” that are very hard or impossible to remove. 

We only use zero degree tips for surface rinsing and at low pressure to lightly rinse the surface. All wood is restored using a 15 – 30 degree tip at 3000 psi. We never get the tip closer than 4 inches to the surface and always go with the grain of the wood. Please watch our video at the top of this page to see an quick example of a fence that we recently restored using this exact method. 

How much water does it take? 

Our pressure washer is commercial grade and uses slightly more water than other pressure washing equipment. We will typically run between 2.8-4.5 gallons of water per minute of use but this is all dependent on the pressure we are running the machine and the size of tip we are using. Plan on a usage of around 200 gallons of water per hour of machine use. 

What is the cost? 

We charge between $100-$165 per hour for most projects which covers labor, fuel, and machine maintenance. We do charge $125 minimums for all projects to cover our time loading equipment and vehicle fuel costs. 

How long should we wait to apply a coating to the surface once cleaned? 

For fencing and decking it is a good idea to let the surface dry for at least 24 hours during warmer temperatures. If an oil based product is being used 48-72 hour dry times are recommended to prevent product failure. Concrete should dry for 24 hours minimum before applying any kind of water based stains or water based sealers. Oil based stains and sealers can only be applied when the surface is fully dry. 

What kind of stains can’t be removed? 

Typically most stains can be removed. The biggest issues we see involve oil or grease on concrete. If concrete is not sealed oil will leech deep into the surface. Once the oils have settled below the surface it is nearly impossible to remove the oil 100%. We can apply concentrated degresers to help lighten the stains before washing. 

We do see some fences with perminate staining caused from the use of drywall screws when fastening the fence. Areas where drywall screws are used will leave black streaks on the planking of wood. Even when pressure washed these stains cannot be removed as the stain works its way deep into the pores of the wood. 

The best solution for a fence that has screw stains is to clean the surface and apply a solid bodied stain to the fence. These are specialized wood stains that have the appearance of paint when applied and will cover the screw stains. 

How often should a surface be pressure washed? 

Usually surfaces should not need high pressure cleaning very often. We would recommend high pressure cleaning at least once per year to keep the curb appeal up. Cleaning serves well as an opportunity to inspect the surface and make sure there is no coating issues that need to be addressed. 

Cleaning your surfaces will give you longer durability with your paints and stains. It also serves well to keep insects like spiders and bees off of your siding and sofit areas. Lighter colored paints tend to stain when exposed to dirt and water runoff from shingle roofing and should be rinsed off the siding when noticed to prevent surface stains.
