Holiday window cleaning is the most requested exterior service in Charleston between early November and mid-December, and it is also the one most people leave too late. If you are hosting this year — family in from out of town, a neighborhood open house, or the annual dinner your family expects — the exterior work wants to be finished by the middle of November, not the week of the event. This guide covers what genuinely makes a difference before guests arrive, the order to do it in, and why booking early matters more here than you might think.
Why Holiday Window Cleaning Comes First
There is a reason window cleaning leads every pre-holiday list. Between November and January the sun sits low, comes through at a shallow angle, and lights up every bit of film on the glass — the same windows that looked acceptable in July suddenly do not. Add interior lighting after dark, when glass becomes the most reflective surface in the room, and the difference between clean and nearly-clean is obvious to everyone sitting in it.
A proper clean before the holidays covers glass inside and out, frames and sills, tracks, and screens. In Charleston it should also deal with what the summer left behind: salt film on homes near the water, pollen residue in the corners of the frames, and irrigation spotting along the lower sashes. If spotting will not come away with ordinary cleaning, it is mineral etching rather than dirt — our guide to hard water spots and salt film on Charleston windows explains the difference, and it matters because etching needs a restoration treatment and more lead time.
If you are weighing up what a professional clean involves, our guide to window cleaning costs in Charleston sets out what drives the number.
The Entry Is the Second Priority
Guests spend longer at your front door than anywhere else outside, usually standing still, often in good light, sometimes waiting in the cold. It is the one part of the exterior that gets properly examined.
- Wash the porch ceiling, columns, and railings. Porch ceilings collect more mildew than almost any surface on a Charleston home because they stay shaded and damp.
- Clean the walkway and steps. The green film on shaded brick and concrete is algae and it is genuinely slippery in the wet — a safety matter before it is a cosmetic one.
- Wipe down the door, hardware, light fixtures, and house numbers.
- Clear cobwebs from eaves, soffits, and light fittings.
- Check that exterior lighting works before it is needed at five in the afternoon.
Then the Wider Exterior, If There Is Time
A full house wash before the holidays is worth doing on its own merits, and the timing works: autumn is a good season to remove the growth that built up over a humid summer, and doing it now means it does not overwinter. Driveways and patios matter if guests park on them or gather outside, which in Charleston they often do — the National Weather Service’s Charleston office records mild winters here, and outdoor entertaining does not stop in December.
Gutters deserve a look too. Live oak and pine debris is still falling through November, and a gutter overflowing onto a walkway you have just had cleaned is a poor result. Our guide to the fall exterior maintenance checklist for Charleston homes covers that side of the season in full.
The Order, and the Timing
Sequence matters more than most people expect, because washing a house after cleaning its windows means cleaning the windows twice.
| When | What |
|---|---|
| Late October | Gutters cleared, house wash, roof assessed. Book now for November work. |
| Early November | Driveway, walkways, patio, porch and steps cleaned. |
| Mid November | Windows inside and out, screens, tracks and sills. Exterior lighting checked. |
| Late November onward | Touch-ups only. Decorate, and enjoy it. |
The other reason to book early is simple availability. Every exterior company in the Lowcountry is busiest in the four weeks before Thanksgiving, and the calendar for that window fills in October. Weather also has a vote: work that needs a dry surface can slip by days when a front comes through, and a schedule with no slack in it is a schedule that misses the date.
What Is Worth Skipping
Exterior painting is not a pre-holiday project unless it is already booked. It needs dry surfaces, a proper cure window, and more calendar than November offers, and rushing it produces a finish that will not last. If a repaint is on your mind, plan it for spring — our guide to how often to repaint a house in Charleston will tell you whether it is actually due.
Equally, do not let a pre-holiday clean turn into a full restoration project. The goal is a home that looks cared for when people arrive. Anything structural that gets found along the way can be dealt with properly in January.
Frequently Asked Questions
When should I have my windows cleaned before the holidays?
Mid November is the sweet spot — late enough that the glass stays clean through the season, early enough to allow for weather delays. Book in October, because the four weeks before Thanksgiving are the busiest of the year for exterior services in Charleston.
How long does professional window cleaning last?
Typically two to four months in Charleston, depending on how close the home is to open water, how much irrigation reaches the glass, and the pollen season. A mid-November clean comfortably covers Thanksgiving through the New Year.
Should windows be cleaned inside as well as outside?
Before guests arrive, yes. Interior glass collects cooking film and dust, and it is very visible after dark when the lights are on and the glass turns reflective. Cleaning only one side leaves the result looking half done.
In what order should exterior work be done before hosting?
Gutters and house wash first, then driveways, walkways, patio and porch, then windows last. Washing anything after the windows are done means spotting the glass and paying to have it cleaned twice.
Is it too cold to clean windows or wash a house in Charleston in November?
No. Lowcountry winters are mild and exterior cleaning continues year-round here. The only real constraint is rain and the occasional cold snap, which is why a little slack in the schedule is worth having.
Can exterior cleaning be done after holiday lights go up?
It is better not to. Washing around installed lighting is slower, carries the risk of damage to the wiring, and produces an uneven result. Have the exterior cleaned first, then decorate.
