Power washing, or pressure washing, is the growing application of high pressure water spray. Produced by specially designed pumps, this spray is a hundred times more powerful than the typical garden hose. On concrete it is used to remove unsightly mold, bubble gum, and other dirt stains. Wooden decks are returned to the look of new wood, void of graying and fatigued finishes. And on houses, the appearance of siding (namely aluminum and vinyl) is greatly improved by removing pollution, mildew, and other signs of neglect.

The majority of our pressure washer chemicals, and other chemicals are environmentally friendly, they achieve great results and save time and money on labor. Pressure Washer approved cleaning solutions are biodegradable, harmless for humans and easy to use.

We only use cleaning solutions that are pressure washer approved. Non-approved cleaning solutions can be harmful for the environment and your property. The chemicals used by St. Louis Pressure Wash are only of the highest quality. Not surprisingly, they are usually the most expensive. This is an area where less professional, lower quality operators in our industry cut corners to make more money or charge less. Don’t be fooled into thinking every pressure washing company is the same. Long-tern results and the safety of your property, your family, and the environment are not worth saving a couple bucks.

Our machines are equipped with downstream injector. We applied apply chemical cleaners under low pressure so that the solution can adhere better to the surface being cleaned. This will allow the formula to react faster and remove the dirt immediately. With our pressure washer cleaning solutions you will get unmatchable results and peace of mind.

Anyone can purchase a pressure washer. Simply owning a pressure washing machine and advertising that you offer a service doesn’t mean you can operate it effectively. A pressure washer in the hands of an unskilled operator can cause a great deal of damage such as damaged, plants and lawn killed, siding blown off, paint peeled from house, and even concrete cut and etched.

NO! Not even close.

Anyone can purchase a cheap consumer-level pressure washer down at the local Home Depot, get some cheap business cards printed, and start claiming they are a professional pressure washing company. Simply owning a power washer and advertising a service doesn’t mean you can operate it effectively and safely. A pressure washer in the hands of an unskilled operator will do a great deal of harm, this is why professional machines, commercial grade cleaning solvents, and the soft washing processes were created.

Commercial power washing and soft washing equipment are specialized, high quality machines requiring expert training to be operated properly in the multiple applications required on even a single property. If someone is offering “the lowest price” they are cutting corners someplace, whether with equipment, insurance or quality of services. Most often it will be all of the above.

Most black stains on roofs are caused by algae (Gloeocaspa Magma). This is an airborne spore that can land on most any roof, and can actually harm your roof by eating into the limestone that is a component of many shingles today. When it rains, the algae can slowly spread down the roof, adding more stains and streaks. We can not only remove the algae, but help keep it from coming back. Major shingle manufacturers recommend that you clean this algae off — but not to use high pressure washing to do it. Have wood shingles on your house? We can clean those too!

NEVER! High pressure powerwashing can be very damaging to the shingles. Plus, it’s simply not an effective way to remove algae stains from roofs. All of our roof cleaning equipment is specially calibrated at a very low pressure to ensure a safe and effective washing away of the stains that are released by our proprietary roof cleaning solvents.

When the St. Louis Pressure Wash technicians finish cleaning your roof, it will be as clean as a new roof. Since it’s impossible to tell how long it will take for a new roof to get stained again, the same holds true for a roof cleaned using our proprietary process. However, warranty against any roof staining for a period of one year. That gives you a guarantee that the roof is completely, squeaky clean and no remnants of the stains are left behind.

DIY roof cleaning products sold at stores like Home Depot and Lowes can cause many problems. Many of these low-quality consumer-level products are toxic to the vegetation surrounding your home. Plus, they are largely ineffective in the long term, as well as the short term as far as roof stain removal goes.

Also, whenever homeowners climb up on their roof, they put themselves at risk of slipping and falling. Roof cleaning is serious business and it’s always best to rely on the professionals.

Be very, very careful here. Many homeowners and contractors alike have tried to use bleach or pool chlorine to remove the dark roof staining caused by algae. The results can be disastrous. Bleach and pool chlorine are dangerous chemicals that can damage vegetation, dry out your shingles, and corrode roof fixtures such as flashing, underlayments, valleys, and boots. Any results that the homeowner sees are often just temporary and the staining is back within a few short months because the bleach merely addresses the surface algae and not the root system underneath the granules.

Algae is a living, growing organism and as such, will continue to grow. Left untreated, in time it can cover your entire roof. A roof covered in algae absorbs heat and results in a superheated attic, raising your cooling costs. In addition, since algae feeds off the organic material in your shingles, left untreated, your roof may require costly, premature replacement. Why allow that to happened when you can have your roof professionally cleaned and restored to its original, natural color for a fraction of roof replacement costs?

Exterior concrete in any region subject to freeze-thaw cycles should be sealed. Many people are surprised to learn that freeze-thaw regions include all of New Mexico, most of Texas, Alabama, Georgia, South Carolina, and even portions of California, Louisiana and Florida. But it definitely includes Missouri.

However, concrete should also be sealed for stain repellence, dust reduction, abrasion resistance, chemical resistance and to maintain an attractive appearance.

Concrete is a porous material that readily absorbs liquids. In freeze-thaw climates, the expansion of frozen liquids can destroy the surface of unsealed concrete. Oil, salt, fertilizer, and other household chemicals can discolor and damage unsealed concrete.

That all depends on the type of sealer that is applied. Most chemically reactive sealers are nearly invisible because they penetrate into the concrete. Solvent-based acrylic resin sealers and epoxies provide significant color enhancement and give concrete a high-gloss wet look. Water-based acrylic resin sealers provide moderate color enhancement and a satin appearance. Urethanes (generally applied as topcoat over epoxy) are available in a wide range of finishes, from matte to gloss. Many sealers can also be colored with translucent or opaque tints.

We will consult with you to determine exactly what type of appearance you want and provide the perfect solution.

Reactive penetrating sealers generally have little effect upon the concrete surface profile or traction. Most topical coatings can affect concrete surface profile, and may require the use of anti-skid additives in areas exposed to foot or vehicle traffic. You can be certain that St. Louis Pressure Wash will use only the most appropriate sealer for your particular situation.

That’s a great question, and in the case of most exterior cleaning and pressure washing companies the answer would be a decisive yes.

However, many years ago when we decided to start offering concrete sealing to our customers, we partnered with Saint Louis Driveway, St. Louis’s leading concrete driveway contractor, to ensure that we were providing the absolute most professional service. We became so good at it that Saint Louis Driveway has since selected us to do the sealing for everuydriveway they install.

Because sealers penetrate the concrete, reactive chemical sealers will last the longest and generally only wear away if the substrate surface itself wears away, which may be 10 years or longer. You can get similar performance with epoxy or urethane sealers, which generally last 5 to 10 years depending on traffic exposure. Acrylic-resin sealers offer the shortest performance life – generally 1 to 3 years. Once again, we will select the best sealer for your particular situation.

Concrete is locally made and can last for many decades with proper care. As sealers extend the useful life of concrete, they are an important component of “green” building and their use can qualify for additional LEED points..

As for the sealer itself, water-based products are generally considered the most environmentally friendly. Some solvent-based sealers can’t be sold in certain states, but new environmentally friendly solvents are now available. St. Louis Pressure Wash only uses the most environmentally friendly sealers, and only ones in full compliance with all state and federal regulations.
