Just bought a home in Columbia? A pressure washing checklist for new owners
By Aisha Vogel · Updated 2026-07-20
Moving into a new home means inheriting whatever maintenance schedule, or lack of one, the previous owner kept. Exterior cleaning is easy to overlook in the chaos of a move, but a little attention in your first few months can save you from a bigger problem later. Here’s a practical first-year checklist.
Start with what you can’t easily see
Gutters and roofline condition should be your first check, even if everything looks fine from the driveway. Clogged gutters you didn’t know about can be quietly pushing water toward your foundation, and you have no way of knowing the last time they were cleared unless it’s documented in your closing paperwork. The same goes for roof algae: it builds up slowly, so a previous owner may not have prioritized it, especially if they were preparing to sell.
| Priority | Why check it early |
|---|---|
| Gutters | Unknown maintenance history, real damage risk if neglected |
| Roof (algae, streaking) | Slow-building issue, easy for a seller to have ignored |
| Siding | Cosmetic now, but establishes your maintenance baseline |
| Driveway and walkways | Lower urgency, mostly cosmetic |
Establish your own baseline
Even if the exterior looks reasonably clean, getting a baseline wash done in your first few months makes it much easier to notice future buildup and judge how fast things get dirty on your specific property. Shaded lots and homes near mature trees will need more frequent attention than open, sunny lots, and you won’t know which category your new home falls into until you’ve lived through a season or two.
Don’t assume you know local pricing yet
If you’re new to the Columbia area, you likely don’t have a feel yet for what’s a fair local price. Get two or three quotes with a matching written scope so you’re comparing equivalent work, not just a bottom-line number. Checking review history and how long a company has operated locally is a better signal than picking whichever name shows up first in a search.
A simple first-year sequence
A reasonable order for a new homeowner without a known maintenance history:
- Gutters first, especially if you moved in during or right before fall or spring debris season.
- Roof inspection and soft wash if streaking is visible.
- House washing to establish a clean baseline and catch any hidden mildew near the roofline.
- Driveway and walkways, since these are lowest urgency and easiest to schedule around everything else.
You don’t need to do all four in one week. Spacing them out over your first few months is reasonable, especially if budget after a home purchase is tight.
What to ask your realtor or the previous owner
If you’re still in touch with the seller or your realtor after closing, it doesn’t hurt to ask directly whether any exterior cleaning was done recently, and if so, when and by whom. Some sellers do a pre-listing wash specifically to help the home show well, which means the exterior could still look decent for a while even if deeper issues, like gutter debris or roof algae under the visible surface, weren’t addressed. A cosmetically clean exterior at closing isn’t the same as a genuinely maintained one.
Watch your first full year
Because you’re new to the property, your first full year is really a data-gathering exercise as much as a maintenance task. Note how fast pollen builds up on your driveway each spring, whether your gutters fill quickly after a storm, and which sides of the house pick up mildew first. That pattern tells you far more about your specific home’s real maintenance rhythm than any generic seasonal guideline, and it’s what you’ll use to plan your second year onward with more confidence.
Keep a simple record
A quick note on your phone with the date and what was done each time you get a service goes a long way, both for your own planning and if you ever sell the home yourself down the line. Future buyers, and future you, will appreciate not having to guess at maintenance history the way you had to when you moved in.

FAQ
- Should I get the exterior cleaned right when I move in, even if it looks fine?
- It's worth at least an inspection walk-through, since you may not know how long it's been since the previous owner had it done. A baseline cleaning also makes it easier to notice new buildup going forward.
- What should I check first as a new homeowner?
- Gutters and the roofline, since neglected gutters cause the most costly damage over time and you may not know their maintenance history. After that, look at siding for mildew and the driveway for staining.
- Is it normal not to know when the previous owner last had this done?
- Very common. Unless it's specifically documented in your closing paperwork, most buyers have no idea. Treat the first year as a chance to establish your own maintenance baseline.
- How do I avoid overpaying as a new homeowner who doesn't know local pricing yet?
- Get two or three quotes with a consistent, written scope so you're comparing the same work, and check review history rather than picking the first name that comes up.
