In pressure cleaning a House Wash refers to the disinfecting and cleaning of the gutter trim, walls, doors and cleans up the windows nicely with a streak free shine.
A house wash primarily uses low pressure chemicals and water. Not as low as a typical garden hose but not as high as a professional high grade pressure washer. Depending on the level of dirt and mildew built up will determine what concentration of chemical we must use to rid the surface of bacteria. For normal bacteria's such as algae and light mildew a low concentration of chlorine and soaps should be used but if we see lichen and orange mildew it is best to go for a high mix to cut down on the dwell time but just be sure to rinse off any surrounding plants during the House Washing process.
Above are perfect picture examples of the mold and mildew that build up day after day on south florida homes. This specific picture was taken at a house wash cleaning we did in Boca Raton Florida a few months back. With the right amount of chemicals these ugly stains will lift up and leave behind a clear bright window. After applying the chemicals to the homes affected area you must rinse off very well to prevent any paint damage such as oxidization.
The best part about cleaning a homes exterior with low pressure is there is zero chances that the paint will be damaged. Hard pressure on a home exterior will wear it away and can risk paint damage. With a low pressure chemical cleaning it is the chemicals that do the cleaning, not the dangerous high presure. Once the solution has done the cleaning you may then rinse off with high volume and low pressure water. This also helps take care of the chemicals smell.
We recommend a house wash be done every 6 months to keep your home looking its best.
