What is included with your window cleaning service?

We are a full service window cleaning company. Our general maintenance window cleaning service always includes both the exterior and interior surface of the glass itself, power washing of the window screens (both window screens and sliding door screens), cleaning of the window frames and sills, and cleaning of the window tracks. Our price and service always includes all of these items. If you prefer to have only the outside of your windows cleaned, we do accommodate exterior only cleanings, though in our experience we have found that most of the time the inside surface of windows are in need of attention almost as much as the outside. An exterior only cleaning would include the exterior surface of the glass and power washing of the screens.



What is not included with your normal window cleaning service?

As noted in the question above there really is no aspect of the window as a whole that we do not clean. More likely to come into play is the subject of certain substances on the glass that are removed or not during normal cleaning. Most of the time when a person needs their windows cleaned they need general maintenance window cleaning. Maintenance cleaning removes dirt, environmental pollutants, bird droppings, bug goop, build-up caused by interior activity (cooking, air conditioning/heating systems, laundry, etc.), and the occasional dog nose smudging or toddler inflicted peanut butter finger prints.

There are basically two sets of items that are not removed through general maintenance window washing: (1) debris commonly associated with post construction or remodeling work, such as paint, plaster, stucco, texture, tape, or window manufacturer sticker debris, and (2) mineral damage due to hard water sources such as landscape irrigation overspray, metal oxidation, or masonry runoff. Removal of these substances falls into the areas of post construction window cleaning and glass restoration respectively. We do specialize in both of these types of services if needed.



What is that magic water that you use?

We employ a pure water cleaning system for cleaning the exterior of all windows. The key to this cleaning system is utilizing the technology of deionized water. Deionization is a physical process which uses specially-manufactured ion exchange resins that bind to and filter out the mineral contents from water producing an extremely high level of purity. The filtration process removes all negative charge in the water caused by minerals and salt. Without these elements present, the water attempts to stabilize itself by becoming very aggressive, seeking negative particles in the form of dirt and other contaminants. The water pulls these contaminates from your windows and washes them to the ground. Finally the water, being void of minerals and salts, dries on the glass absolutely spot-free. The outcome is windows cleaned more thoroughly and with results superior to any other method of cleaning. There is absolutely no chance of streaking, and because there is no soap residue left behind to attract dust, windows actually stay cleaner longer!



Do you wash all my screens?

Yes. We apply soap to the screens and power wash them with water. It is common among many window cleaning companies to dry dust screens with a dust brush. In our opinion that is just not an adequate way to clean screens. Just the nature of the window screen design – a lattice work of tiny horizontal and vertical surfaces – creates a perfect device for collecting and holding dirt and grime. They need thorough washing with soap and water to release all that trapped dirt. Washing all of the screens with every window cleaning is something that we feel very strongly about. Putting a dirty screen back on a clean window is an injustice. Besides making your windows look better, a clean screen will keep your window cleaner longer and, as reported by many of our clients, make the air in your house less dusty and smell fresher.



When is the best time of the year to have my windows cleaned?

There really is no bad time to have your windows cleaned. Often times individuals are concerned about having their windows cleaned during the winter months fearing possibility of rain. Rain is not a concern and winter months are as good of a time as any to clean your windows. One of the best times to have them cleaned, regardless of time of year, is when they are dirty!



How often should I have my windows cleaned?

How often is really up to personal preference, and what level of tolerance a person has for dirt. Most of our customers that have requested to be on a regular maintenance program have us come either quarterly (every 3 months), or every 6 months. Though a few of our customers ask us to come more frequently, generally you will not need to have your windows cleaned more than every three months (the methods we use actually keep your windows cleaner, longer). In our opinion, a person really needs to have their windows cleaned at least twice a year.



Is it going to rain?

Though we are not meteorologist, we can tell you with some level of certainty that is will rain at some point in the future. Don’t despair though, rain will not affect your clean windows – it’s the dirty windows that you have to worry about, see below...



What if it does rain?

This may be a tough one to grasp, but rain does NOT make your windows dirty. Rain is relatively clean, and unlike tap water that comes out of sprinklers and irrigation systems, rain is devoid of minerals – which means it will not leave water spots. The reason people think rain makes their windows look dirty is because their windows were dirty to begin with. If your window is dirty and particularly if your screens are dirty and rain gets them wet, guess what you are left with? Mud! So it is not rain making your windows dirty, it is dirt that makes them dirty.

When we clean your windows, we clean the glass itself, the window frame and we wash your screens (yes, wash the screens with soap and water – we do not simply dry brush them as is common with many window cleaning companies). Furthermore, all of the exterior glass is cleaned with a pure water cleaning system, so no soap residue is left behind. So what is left behind after we have cleaned your windows? Nothing! That means if it were to rain the day after it would have no impact on your clean windows. If the clean rain water was to come in contact with your clean windows it would have no dirt to make mud out of, and because it is mineral free it would dry without spots! In many cases windows are covered by roof lines and rain cannot come in contact with them anyway. We actually have the ability to clean your windows while it is raining and get perfect results!



I have hard water deposit on my windows, can you get it off?

Absolutely. We specialize in glass restoration and particularly in the area of mineral deposit damage. Mineral deposit damage on glass is commonly caused by contact with hard water sources in residential settings (i.e. yard sprinklers), but can also be caused by metal oxidation and masonry run-off, or a combination of sources. What caused the mineral damage? How long it has been there? Is it superficial or has it etched the glass? ...These are all factors that go into what approach is required to restore the glass surface. We are very knowledgeable in this subject can almost always guarantee 100% removal of mineral damage.



I just had my house completely remodeled and the windows are a mess from all the construction!?

No problem, we specialize in post construction window cleaning. Post construction window cleaning is a very specialized proficiency. Besides simply cleaning dust and dirt that is kicked up during the construction process, it also involves the removal of construction debris that includes substances such as paint, plaster, stucco and texture, cement, tape residue, and window manufacturer stickers. Safe removal of these substances requires a particular subset of knowledge and training, chemical use, and specific tools. We are well versed in these techniques and potential glass quality issues that can come into play. Please give us a call for more information.



Are you licensed and insured?

Yes. We maintain full insurance coverage that includes a $1 million dollar general liability policy, California workers compensation insurance, and vehicle insurance, as well as bonding and business licensing. A copy of our current certificate of insurance can be found HERE. Being fully insured is something that we feel very strongly about – it protects both us and our customers.



Do your workers undergo any kind of background check?

Without exception. All our staff MUST go through an extensive screening process that includes personality assessment, full criminal background investigation, DWV driving records, and drug testing. We never utilize sub-contractors – all of our staff are under our employment, following our hiring process, training program, and safety procedures.
