Mallard Systems Property Cleaning FAQs

Each Mallard crew consists of two team members. One team member will water extensively before, during, and after the cleaning and sanitizing takes place. We will also tarp any plants in the drip line of an un-guttered section. All downspouts will be bagged to collect the cleaning solution during cleaning and sanitizing. There is the potential for plants to get stressed during the cleaning and sanitizing process. If there are any plants killed during the cleaning process, Mallard will pay to have these plants replaced.

Our cleaning and sanitizing process was designed in compliance with manufacturer guidelines to ensure that damage to your shingles and tiles does not occur. Our cleaning solution is applied with a low-pressure spray and thoroughly rinsed using pressure no stronger than a garden hose. It is best to avoid high pressure when cleaning and sanitizing roofs to prevent damage to tiles and shingles. 

Yes. Our cleaning and sanitizing solution breaks down into salt and water. It does not present any environmental hazard.

We reseal and recoat tile roofs. Tiles on roofs that have lost their color can be recoated to look like new again. Please contact us regarding this service.

The cleaning and sanitizing solution we use contains a low concentration of bleach - similar to that of household bleach. This cleaning and sanitizing solution may be a mild or moderate irritant to some but shouldn’t pose a health hazard. As is the case with many household cleaners, children and pets should be kept away when the actual cleaning is taking place.

Yes. We can customize a package of semiannual and annual cleaning and sanitization for you based on your needs. These packages include discounted pricing, prioritized and convenient scheduling, and allow for easy year-round maintenance of your curb appeal. 

Mallard Systems will provide at no additional charge the service necessary to maintain a spot-free absence of mold, mildew, and algae from your roof for one year from the first cleaning and sanitizing date. This warranty covers shingle, concrete tile, clay tiles, slate, and any composite roofs that have no water pooling. This spot-free warranty is transferable to the new owner of the property. Extended warranty periods may be offered at the discretion of Mallard Systems. 

We clean and sanitize all exterior surfaces, including roofs, the exterior of your residence, pool decks and pool cages, driveways and walkways, pavers, and exterior windows. We currently do not provide any cleaning inside of your property. 

Before starting, our cleaning specialists will thoroughly inspect the property to create a cleaning and sanitizing plan that includes every corner of your property. 

Recommended services include:

• Low-pressure chemical cleaning and sanitizing to remove mold and algae
• Cleaning, sanitizing, and degreasing heavy foot traffic areas
• Hot water pressure washing to remove gum
• High-pressure washing
• Irrigation rust removal

Various algae, molds, and mildews accumulate on roofs due to the warm, humid Florida weather. The black streaks are algae called Gloeocapsa Magma. These pores are always in the air and will attach to your roof surface. Once there, they will continue to grow and spread until killed off during proper roof cleaning and sanitization.

Yes. We have full liability and workers comp insurance (not an exemption). We can provide you with copies of our insurance certifications at any time. This is an easy request to satisfy for companies that have insurance. If a contractor you are doing business with has a problem with providing certifications, this should be a red flag. 

Yes! We work indirectly through general contractors if the cleaning and sanitization is one part of a larger project. Our team has years of experience providing professional cleaning and sanitizing services in whatever manner best suited for our clients. 

Quoting a roof or exterior cleaning one the phone may be an easy thing for some companies to do. Still, it does not allow for an accurate assessment of the cleaning and sanitization that is needed, nor does it identify potential problems. It is best for you and for us to put our eyes on the job, allowing our crew to be fully prepared for when they arrive to do the cleaning and sanitization—no surprises for anyone.

Yes. Please water the plants nearest to the house the night before. On the day of service, please make sure all windows are closed, water is accessible, and that the work area is clear. If you are planning on having your house painted, please let us know so we can schedule cleaning and sanitization before painting.

Yes. However, due to some residual odor from the cleaning and sanitizing solution and the dirt itself, most people prefer to wait 24 hours.

To entirely kill off the mold and algae growing on your roof, a strong cleaning and sanitizing solution is needed. Plants can sometimes become temporarily stressed as a result of the cleaning and sanitization. As a precaution, one team member will water extensively before, during, and after the cleaning. We will also tarp susceptible plants that are in the drip line of any un-guttered section.
