How often should windows be cleaned?

Most central Iowa homes do well with two cleanings a year — spring after pollen and fall before winter. Annual members get their visits scheduled around the property, so it's handled without you having to think about it.

Do you clean from the inside too?

Yes. Standard service includes both sides of every accessible window, plus frames, sills, and tracks. Tell us if specific rooms are off-limits.

What about hard-water stains?

We can treat them. Hard-water removal is a separate process — we'll identify the panes during the walk-through and quote it openly.

How much does window cleaning cost in Des Moines?

Pricing varies by pane count, story height, screen condition, and storm-window count. We give a precise written quote in person after the walk-through — no online estimates and no pricing surprises.

Yes. JBL Exterior Pros is fully insured for both property damage and worker liability. We can email a current certificate of insurance on request before any work begins.

Do you clean storm windows?

Yes. Sherman Hill, Beaverdale, and other older Des Moines neighborhoods have homes with original storm windows that need separate handling. We remove, clean both sides, and replace them — adds 30–60 minutes per typical home.

What about window screens?

Included on standard service. We remove every accessible screen, vacuum and rinse off pollen and dust, and replace. Damaged screens we'll flag during the walk-through but won't replace without your approval.

Can you reach upper-story or atrium windows?

Yes. Our water-fed pole system reaches up to 60 feet, which covers nearly every residential application in central Iowa. For atrium glass or unusual access, we'll walk the property and confirm approach on the in-person quote.

— Why Norwalk homes need this

Window Cleaning, the Norwalk way.

Norwalk runs a wider mix than the inner suburbs. The north side and around Echo Valley is 1980s–2010s subdivisions with conventional vinyl siding and asphalt shingles. The rural-edge properties south and west of town are larger-lot homes — some original farmhouses, some 1970s ranches on acreage, some newer custom builds. Brick veneer is more common here than in the newer planned suburbs. A few homes still have cedar shake or T1-11 wood siding that needs the gentlest soft-wash chemistry we run.

Norwalk's lower density means longer drives between jobs and longer runs of fence, deck, and pavement per property. The rural-edge properties carry heavier autumn gutter loads — mature trees plus open field exposure means leaves AND seed pods AND pine needles in one stretch. Pollen drift from surrounding farmland in spring shows on north walls and on solar panels faster than in dense suburban zones. Less HOA control means more independent decisions about exterior maintenance cadence — we see a wider range of property conditions.

— Plain English

Window Cleaning, in plain English.

Window cleaning is the process of removing dirt, pollen, hard-water spots, sap, and atmospheric film from both interior and exterior glass — plus the frames, sills, tracks, and screens that surround it. The right method depends on the height (water-fed pole for upper stories, ladder + squeegee for lower), the glass type (Low-E and tinted require ammonia-free solutions), and the water source (tap-water cleaning needs a squeegee finish; deionized purified water dries spot-free on its own). Done correctly, cleaning a year's worth of accumulated film restores visible clarity that homeowners often don't realize they've lost — and protects window seals and frame finishes from the corrosive effects of long-term grime buildup.

— Local conditions

Central Iowa window cleaning is its own thing.

Central Iowa puts windows through four distinct seasonal stresses. Spring pollen — mid-April through late May — coats glass in a yellow-green film that water alone won't clear. Summer brings hard-water mineral deposition from lawn-sprinkler overspray plus agricultural dust drift from western neighbors. Autumn drops oak, maple, and walnut debris onto north-facing sashes, and tannin-rich sap leaves stubborn staining. Winter freeze-thaw etches the glass that already carries soft-water spots. Most central Iowa homes benefit from twice-yearly cleaning — late April after pollen and late October before snow. Older neighborhoods like Sherman Hill and Beaverdale have original storm windows that need separate handling; newer Ankeny and Waukee builds have larger thermal-pane glass with no storms but bigger surface area per home.

— What to watch for

Window Cleaning mistakes other contractors make.

01
Spray-and-wipe with paper towels
Quick to do but leaves lint, residue, and uneven streaks. Real window cleaning uses a wet/dry tool sequence — applicator pad to scrub, squeegee to lift water in a single pass, microfiber detail to finish edges.
02
Ammonia-based cleaners on tinted or Low-E glass
Most central Iowa homes built since 2000 have Low-E coatings on at least one pane face. Ammonia (the active ingredient in most blue glass cleaners) degrades the coating over years. We use ammonia-free chemistry by default.
03
Washing in direct sun
Solution flash-dries before the squeegee can pass, leaving permanent streaks on the glass. We schedule around exposure — east-facing windows in afternoon, west-facing in morning.
04
Skipping the frame, sill, and track
Loose dirt left in frames falls back onto fresh glass within hours, especially the next time a breeze hits. A real window cleaning includes the surrounding surfaces, not just the glass.
05
Pressure-washing exterior windows
Forces water past frame gaskets and weep holes, eventually damaging seals and causing interior leaks. Pressure has no place on glass — chemistry and squeegee technique do the work.
