DIY vs Professional Window Cleaning: What to Expect
Where a squeegee and a weekend genuinely get you, and the three jobs where it stops being worth your Saturday.
The short answer
Plenty of window cleaning is worth doing yourself, and we would rather say so than pretend otherwise. Ground-floor glass on a modest house, cleaned properly, is a satisfying Saturday and the results can be genuinely good.
Three things move it out of DIY territory: height, mineral deposits, and volume. Any one of them is a reasonable point to hand it over. All three at once — which describes a lot of Southern Utah homes — and it stops being a close call.
What you can absolutely do yourself
- Interior glass. No ladder, no weather, no risk. Easily the highest-value DIY work.
- Ground-floor exteriors you can reach with both feet on level ground.
- Screens and tracks. Unglamorous and genuinely effective between professional visits — here is the ten-minute routine.
- Spot-cleaning. Dog nose prints, small hands, the one pane by the back door.
- A rinse on the worst elevations. Hosing the south and west glass between cleans genuinely slows mineral buildup.
Doing it properly
Most bad DIY results come from the same handful of mistakes:
- Work in shade, or early. The single biggest one. Solution that dries before you squeegee it will streak no matter what you do next.
- Use very little detergent. A few drops in a bucket. Excess soap is what leaves the film people mistake for bad technique.
- Rinse the grit off first. Red dust dragged across glass under a cloth is how scratches happen.
- Keep the squeegee blade clean and sharp. Wipe it between every pass. Replace it when it nicks.
- Finish the edges with a dry microfiber, not the same cloth you have been wiping the blade on.
Where DIY stops making sense
1. Anything needing a ladder
This is the one we would push hardest on. The risk in window cleaning is not the glass, it is the ladder — and Southern Utah yards make it worse than average, with gravel beds, slopes and rock landscaping that give a ladder nothing flat to stand on. Two-story entry glass and great-room windows are routine for us because we have water-fed poles, proper ladders and the insurance to match. Falling off a ladder to save a couple of hundred dollars is a bad trade.
2. Mineral spotting that will not wash off
Washing removes dust and grime. It does not remove the deposits that overspray and hard water leave behind — those need a treatment, and the products sold for household use mostly are not up to established buildup. There isa home method worth trying on fresh spotting, but once it is years old you are unlikely to get there.
3. Sheer volume
Homes built here in the last twenty years have a great deal of glass. Doing thirty windows inside and out, plus screens and tracks, is not an afternoon — it is a weekend, twice a year, forever. Some people enjoy that. Most work out that their Saturday is worth something.
Side by side
| Doing it yourself | Having it done | |
|---|---|---|
| Ground-floor glass | Very doable | Convenience |
| Upper-story glass | Genuinely risky | Routine, and insured |
| Mineral deposits | Only fresh spotting | Treated properly, or told honestly it is etched |
| Screens, tracks, frames | Doable and worthwhile | Included as standard |
| Water spots from your own rinse | Likely — the tap water here causes them | Purified water dries clear |
| Time for a typical home | A weekend | A visit |
| If something is missed | Back up the ladder | 48-hour free re-clean on qualifying work |
The middle ground
The split most of our clients land on: they do the insides when they feel like it, and we do the outsides, the screens and anything with height on a regular rhythm. You keep the easy, satisfying part and hand over the ladder and the minerals.

Common questions
Is professional window cleaning worth it?
For ground-floor glass on a small house, often not — that is a genuinely doable Saturday. It becomes worth it when there is upper-story glass, when mineral spotting needs treatment rather than washing, or when the time it takes you stops being worth the money it saves.
Why do my windows streak when I clean them?
Usually one of three things: cleaning in direct sun so the solution dries before you finish, too much detergent in the mix, or a squeegee blade that is worn or being wiped with a dirty cloth between passes. All three are fixable.
What do professionals use that I do not have?
Purified water is the main one. Removing the minerals means the water dries without leaving its own spots, which matters enormously here. Beyond that it is water-fed poles for height, proper squeegees, and treatments for mineral deposits that are not sold for household use.
Can I clean my own second-story windows?
You can, and every year people are hurt doing it. Ladder work on uneven desert landscaping, gravel beds and slopes is the genuinely risky part of this job — not the glass. That is the one place we would actively suggest not doing it yourself.
Will I save much money doing it myself?
You save the labour and spend the time, plus the equipment if you are starting from nothing. Where the maths turns is on homes with a lot of glass or any height, because the hours climb faster than the savings do.
Can I do the inside and have you do the outside?
Yes, and plenty of clients do exactly that. Exterior-only is a common booking — the outside is where the dust, overspray and mineral spotting are, and it is also the part that needs the ladder.
