Will Your Outdoor Cleaner Kill Your Plants?

Posted by [email protected] on November 11, 2016 at 2:00 PM Comments comments (0)

If you are like me, you take pride in your yard.  When the weather is nice, I enjoy spending time outdoors and doing tasks around the yard. There is also that sense of satisfaction when you’ve finished mowing the lawn, trimming the bushes or planting some flowers.


One of my friends recently worked on some of her flowerbeds and then realized her patio needed cleaning. She went to the home improvement store and got some outdoor cleaning solution. At the end of the project, the patio looked great, but the flowerbeds she had worked on were nearly dead, all because of the cleaning solution!


A lot of outdoor cleaning products use chlorine bleach. It’s a great product to kill mold and mildew, but unfortunately it can kill a lot more than that. If it isn’t used properly, it can harm or even kill your landscaping, impacting the surface of the leaves and the growth.


It is very important that if you chose to clean your decks, porches, patios, siding, or other outdoor surface on your own that you follow the directions on the bottle very carefully. Do not just apply the chemicals and clean. They often have to be mixed or diluted before applying them to the space.

Deck cleaning & sealing

Posted by [email protected] on July 28, 2016 at 7:50 AM Comments comments (0)

Approximately 1/2 the homes in the United States have a wooden deck, siding, fencing, or roof. Without protection wood rapidly deteriorates from the following elements:


Water. Water is absorbed into the wood and washes out the natural wood resins and color. Freezing/thaw cycles can splinter and crack the wood. Also water promotes algae, mold, and mildew growth and rotting.

Sun Light. Ultraviolet (UV) rays bleaches the wood fibers and breaks down the cell structure.

Mold, Mildew, Algae, and Fungus. Wood and moisture are a natural food source for mold, mildew, algae, and fungus. This generally causes a black, green or gray discoloration.

Contamination. Contamination comes in the form of food, dirt, atmospheric pollution, etc. This is a good food source for Mold, Mildew, Algae, and Fungus.

Wood in poor condition reduces the value of a home. Proper cared for wood adds to the value and appearance of a home. There is more than one way to clean and seal a deck. We will examine the most popular techniques and point out some of the advantages and disadvantages of each. You will have to choose the technique that you prefer.

Cleaning Pressure:


PSI (pounds per square in of pressure): The PSI for pressure washings decks (wood) varies from 300 to 3,000 PSI at 3 to 6 GPM for Professional Deck Cleaners. Too much pressure will cause the wood to furr. If this happens you will need to sand with fine sandpaper or steel wool to knock off the furred surface. A lot of Deck Contract Cleaners use a variable pressure wand (like the ST-54 61" Double Lance Wand) so that they can adjust the pressure as necessary. Using low pressure and letting the chemical (like DSR-50 or DSR-49 Deck & Siding Restorer) do the work will avoid furring the deck. Hint: use the underside of the deck to test the PSI. You should start out with as low as pressure as possible then increase the pressure as necessary.


Another way to lower the pressure is to change the spray nozzle to larger size. This will decrease the pressure and will work on any pressure washer.


Some Contract Cleaners use heavy concentrations of either Chlorine Based Bleach, Oxygen-Based Bleach, or Sodium Hydroxide based cleaner and use only garden hose pressure to clean the surface.


Cold Water Washers are normally used as heat will expand and cause the wood to absorb too much water. However, in heavy grease or oil and sealant stripping situations heat may be required.

Sealing the Color and Brightness In:


The first and most important step in sealing any deck is to choose the proper sealer. There are many different sealers on the market. The best one to use is the one that will afford the maximum protection for the minimum cost. There are many companies who claim that their product will deliver what you need. Experience has taught us that a large percentage of these claims are false. Purchase advisedly, see the references at the end of this article. About the only product that most Contract Cleaners will agree on is that "Thompsons" is not a product of choice!


A good sealer will have UV protection, mold and mildew resistant, and a life of several years.


After cleaning the surface to be sealed and allowing sufficient drying time (at least 24 hours) you are now ready to apply the protective coating. We recommend the use of an airless spray rig, paint brush, and a roller for material application. Apply properly and read the manufacturer instructions carefully.

Pressure washing in the winter

Tips For Pressure Washing In The Winter

Posted By admin on Feb 12, 2016 |

Even in the colder months, your home can get dirty and experience unsightly mold or mildew. Pressure washing is an effective way to get the dirt and debris off of your siding, sidewalks, and other exterior surfaces. If you would like to pressure wash in the winter but you’re unsure of how the bitter cold temperatures will affect the process, here are some tips that can make the process easier.

Make Sure It’s Safe

Since snow and ice can pose several safety hazards, make sure you are working in a safe environment before you start pressure washing. If you had planned to go up on the roof to wash the upper part of the house, for example, and it’s covered in snow, wait until the snow has melted. If your sidewalks are frozen and you’re concerned about slipping and falling, wait until the ground has thawed before you begin washing. No matter what you decide, you should always dress warmly and wear face and hand protection to keep you from getting too cold while you work.

Make Pressure Washing Easier

If you use a chemical mixture in your pressure washer to kill mold, remember that chemicals tend to take more time to work in the cold since they need to warm up in order to activate. Make sure you have ample mold killing solution to get the job done since you will most likely need to use more than normal. Be absolutely sure that the chemicals are thawed before using them, since they can separate if they become frozen. Try not to pressure wash areas that are in the shade in the winter. Areas that are hit with direct sunlight will make them easier to clean off since they’ll be exposed to a bit of sunshine. Make sure you start later in the day so your surfaces have had some time to warm up a bit. Temperatures above 32 degrees Fahrenheit (freezing) are ideal.

Take Your Time

The best way to ensure you do a thorough job when you’re pressure washing your home is to simply take your time. Use slow, sweeping motions to make sure you are removing all of the dirt and debris from each section the first time. If it gets too cold, simply wash one section of your home or other surface area one day and return the next day to continue. It is better to be safe and stay warm than to remain outdoors until the whole project is done and you’re suffering from frostbite. If you decide to pressure wash one section at a time, be sure to store your machine in a warm place so that the contents of the tank don’t freeze and your line does not get clogged from becoming frozen. Although pressure washing isn’t nearly as common in the winter, it can still be done as long if you follow these helpful tips.

Pressure cleaning, Power washing

Concerned about high pressure or harsh chemicals?

This paragraph is meant for you! Many companies advertise non-pressure as their biggest selling point for their exterior cleaning process. While using low pressure is very important, what this type of non-pressure process typically means is that they are going to apply very large quantities of very strong chemicals to your home so they can do the job as quickly as possible. We hear all the time about other companies who have killed all the plants or ruined parts of a house because they used excessive amounts of excessively strong chemicals in order to race in and out of a job. It’s all about balance, and while it does take a few more minutes and a little extra care to clean the way we do, we are happy to take the time to do the job right so that you can have a beautiful home without risking ruin for your property.

Bottom line? Our pressure washing service is guaranteed to safely and effectively revitalize your property by removing years of unsightly dirt, bacteria, mold, mildew and other stains. Also, consider our separate roof cleaning service if you have streaks and algae stains on your shingle, tile, or metal roof.

We 100% guarantee our power washing service for 1 week (excluding normal accumulation of dirt and debris). This guarantee period is meant to give you adequate time to be sure the job has been done properly and to your satisfaction. If during this period you are not satisfied with the work that was done for any reason, please contact us so we can make it right.

Remove that Mold and Mildew before it gets Dangerous

Have you ever walked around your home and noticed some spots that just don’t look right? Are they white, gray or black? If so, that’s mold and mildew, a natural evil of the outside world. While it is natural, it can cause some health concerns if left to its own devices.


If left outside, mold and mildew aren’t a major concern (except that it looks awful), but it can work its way inside your home even if it is on your siding outside. Spores get in through cracks, windows and doors. It can cause some health problems (especially for the elderly and young) including headaches, difficulty breathing and asthma. To avoid this, pay attention to what is happening on the outside of your house as well as in.


Mold and mildew grow best in moist and shady areas. On your property, you may have sections that you could describe that way, but others may not be as easy to recognize. Overflowing gutters can cause a lot of moisture on your siding as it rolls down as well as around your laundry dryer exhaust.


The first step in protecting you and your family is to be observant and take action as soon as you see any mold and mildew on your siding. If you catch it early and it is present in an easy to reach spot, you may be able to clean it off yourself.


Make it a habit to spray down your siding a few times a year to get rid of any, dirt, mold and mildew that is loosely attached to the surface.


Do not ever paint over built up mold and mildew. You are just locking it in and it can continue to grow and cause damage.


Pressure washing siding should be done periodically if mold and mildew are a problem on your property. Due to the strength of a pressure washer, we suggest having a professional pressure washing company. Damaging siding with a pressure washer will just cause more issues instead of fixing the mold and mildew one.


At Quality Pressure Cleaning, we use our three-step process to clean and protect vinyl siding. Our pre-soak foam will kill the mold and mildew and loosen it from the surface before pressure washing it all away.
