Vinyl Siding Pre-Wash Inspection Checklist for New Hampshire Homes
A vinyl siding pre-wash inspection helps a Southern New Hampshire homeowner separate ordinary surface soil from conditions that need repair, testing, or special protection before exterior cleaning begins. The goal is not to choose pressure settings or cleaning chemistry. It is to document the house accurately enough for a safer, clearer project plan.
For a broader explanation of siding-cleaning methods and common risks, read ACME’s vinyl siding cleaning guide. Use the checklist below to prepare for a property review without repeating that how-to guidance.
Walk the property before anything is moved or covered
Start with a slow walk around the building in daylight. Take one wide photo of each wall, then closer photos of damaged panels, open joints, stains, fixtures, and areas where runoff could collect. Include the ground below the siding so plants, decks, patios, window wells, and neighboring property are visible.
| Inspection area | What to record | Why it belongs in the project plan |
|---|---|---|
| Panels and seams | Cracks, loose pieces, warping, gaps, and prior repairs | Existing damage may need repair or a restricted work area |
| Windows and doors | Failed caulk, damaged trim, loose screens, and known leaks | Openings may need protection and reduced water exposure |
| Fixtures and utilities | Outlets, lights, cameras, vents, meters, and exposed wiring | The work plan must identify items that cannot receive direct application |
| Surface condition | Oxidation, chalking, paint, algae, rust, soot, and irrigation staining | Different conditions can require testing and different expectations |
| Surroundings | Plants, painted trim, decks, masonry, vehicles, slopes, and drains | Protection and runoff planning depend on what is below and beside the siding |
Mark conditions that should pause routine cleaning
A checklist should flag situations that need a closer review before ordinary exterior cleaning proceeds. Examples include visibly loose siding, open electrical components, active water entry, severely deteriorated trim, unstable access, and an unknown coating that reacts during a small test.
Documenting a concern does not diagnose the building or prescribe a repair. It gives the homeowner and contractor a shared record of what was visible before work and what needs a separate decision.
Build a useful photo set
- Photograph each elevation from far enough away to show the full work area.
- Add close views of damage, staining, openings, and delicate adjacent finishes.
- Include a reference object or wider view when the size or location is hard to understand.
- Note which side of the house each photo shows.
- Record recent leaks, repairs, painting, or previous cleaning that may not be obvious in a photo.
Keep the photos together and avoid editing away color variation. A consistent record helps distinguish pre-existing condition from the expected cleaning result.
Prepare questions for the estimate
Ask how the proposal addresses the specific conditions you documented. Useful questions include which areas will be tested first, what will be protected, how runoff will be managed, which conditions are outside the cleaning scope, and what result is realistic for oxidation, fading, or permanent material damage.
The written scope should identify exclusions as clearly as the work itself. Cleaning can address removable contamination, but it cannot restore faded material, repair impact damage, or correct water intrusion.
Use the checklist as a planning record
Save the inspection notes, photos, and proposal together. After the project, compare the same elevations under similar light. This creates a practical record without turning a homeowner checklist into a do-it-yourself operating guide.
