I get this question a lot. Usually from someone who just moved to Oklahoma from out of state and cannot figure out why their windows look filthy six weeks after they cleaned them. The short answer is twice a year for most homes. The real answer depends on where you live, what your sprinklers are doing, and whether there is construction happening on your street.
Let me break it down.
Oklahoma has three things working against your windows that most states do not deal with all at once: red clay dust, heavy pollen from March through May, and mineral-heavy water coming through your sprinkler system. Add in the wind we get out here and your glass is catching all of it. A homeowner in Oak Tree called us last spring because she could not see her backyard through her kitchen windows. She had cleaned them in January. By late April, between the cedar pollen and the red dust blowing in from the fields west of town, the glass looked like it had not been touched in two years.
That is not unusual. That is Oklahoma.
For most residential homes in Edmond and the OKC metro, I recommend cleaning your windows twice a year. Once in late spring after pollen season wraps up, usually late May or early June. And once in the fall, around October, before the holidays hit and you have family coming over. That schedule keeps your glass clear through the seasons when you actually want to enjoy the view.
But there are situations where you need it more often.
If your sprinkler system is hitting your windows, you should be on a quarterly schedule. I cannot stress this enough. Sprinkler overspray is the single fastest way to destroy glass in Oklahoma. The water here is loaded with calcium and magnesium. Every time those sprinklers fire at 4 AM and mist your west-facing windows, they leave behind mineral deposits. Those deposits do not wash off with rain. They bond to the glass. A few months of that and you are looking at hard water stains that need professional removal, not just a squeegee.
A homeowner off Boulevard had sprinkler lines hitting every west-facing window on his house. He did not notice until the stains were so thick the glass looked frosted. That was a hard water restoration job, not a regular cleaning. It cost three times what a standard window cleaning would have. If he had been on a quarterly cleaning schedule, we would have caught it early and kept the glass clear.
Here are the signs it is time to call us:
You can see a film or haze on the glass when sunlight hits it at an angle. Your screens look gray instead of black. There is grit or dust sitting in the window tracks. You notice water spots or white mineral buildup on the exterior glass. Your neighbors just got their windows cleaned and now yours look bad by comparison.
If you live near new construction, bump your schedule up. The stretch along Covell and Kelly has had nonstop building for the past two years. Every time a foundation gets poured or a lot gets graded, the dust cloud settles on every house within a quarter mile. If that is your neighborhood, quarterly cleaning will save you a lot of frustration.
Homes in Deer Creek and Coffee Creek tend to catch more wind-driven dust because of the open fields to the north and west. If you are out there, you will probably notice your windows getting dirtier faster than someone in a more established neighborhood with tree cover.
My recommended schedule for Oklahoma homeowners:
Standard homes with no sprinkler overspray: twice a year, spring and fall. Homes with sprinklers hitting windows: every three months. Homes near active construction: every three months until building wraps up. Homes with hard water stain history: twice a year with a hard water inspection each visit.
Most residential jobs in Edmond run between $150 and $400 depending on window count and whether you are one story or two. Getting on a regular schedule means each cleaning goes faster because there is less buildup to deal with. Some of our repeat customers pay less per visit than first-time cleans because the glass stays in better shape between appointments.
One thing people overlook is interior windows. The outside of your glass catches all the Oklahoma weather, but the inside collects cooking grease, fingerprints, pet nose prints, and dust from your HVAC system blowing all winter. Interior glass does not get as dirty as exterior, but after six months you will notice it when the sun hits at the right angle. We clean both sides on every visit because a clean exterior with a greasy interior still looks off.
Another factor specific to Oklahoma is storm season. We get strong winds from March through June, sometimes with hail. After a big storm, check your windows for pitting and debris marks. Hail will not break most residential glass outright, but it can leave micro-chips and roughen the surface. A roughened surface holds dirt faster than smooth glass. If your windows took hail damage, cleaning them more often helps you stay ahead of the buildup while you decide whether to file an insurance claim for replacement.
