Pressure washing in Charleston, WV: Plan the Job

Compare written quotes for your property

Give each provider the same photos and surface list. Include close views of stains, loose paint, damaged joints, and places where water has entered before. Add wider views showing access, planting beds, and drainage. Request an inspection before accepting a final price if the provider cannot assess the work from those photos.

Have the quote separate cleaning from optional work such as moving furniture or treating individual stains. Record who supplies water, what the crew will rinse and clean up, and which surfaces they will exclude. Establish what happens if a stain remains after the agreed treatment, including whether another visit would cost extra.

Request proof of insurance and identify the business performing the work. Settle how you will report damage and who will respond. Keep before-work photographs with the agreement. Compare the total price only after each offer covers the same work, access arrangements, and responsibilities.

Choose a method for each material

Require a treatment plan for each surface instead of accepting a promise to wash the whole exterior with one method. Have the provider name the equipment and products they intend to use and explain protection around windows, doors, fixtures, and plants. For roof or upper-wall work, include the access plan in your discussion.

Agree on a test area and inspect it before authorizing the remaining work. Point out existing defects and request exclusions or repairs where the provider considers cleaning unsuitable. Document the stopping procedure if treatment changes the appearance or reveals damage. Avoid approving a pressure setting or chemical mixture you cannot evaluate.

Resolve runoff handling before work starts

WVDEP lists the City of Charleston among its municipal separate storm sewer system permittees. The agency explains that an MS4 collects or conveys stormwater and is distinct from a combined sewer or sewage treatment plant. You should therefore confirm the destination of wash water rather than assuming a nearby street drain leads to treatment. [2]

Walk the route from the cleaning area toward drains, ditches, and property boundaries with the provider. Record the proposed containment, collection, and disposal arrangements in the agreement, along with who will obtain any needed confirmation. WVDEP's overview does not specify disposal requirements for your individual job. [2]

Check historic boundaries before approving treatment

Charleston's Planning Department identifies properties within the original East End Historic District as subject to the Historic Landmarks Commission's design review process. The city distinguishes that district from the East End expansion and other National Register districts. Use the city's district map to check your address before assuming which process applies. [1]

For an address within the original district, describe the material, condition, proposed product, and cleaning method to Planning. Seek a determination about consultation or review before approving treatment. The city's preservation overview does not establish a blanket approval requirement for washing or provide washing specifications. [1]

Schedule around the forecast and household access

NWS Charleston explains that cold air can pool in valleys and that near-ground temperatures can fall below standard observations during clear, calm conditions. NWS also urges readers to follow temperature forecasts outside the growing season, when frost and freeze headlines stop. This regional guidance supports checking overnight conditions around wet paths and outdoor water connections; it does not establish today's alert status. [3]

Agree on postponement conditions, notification, and a backup date. Discuss how the crew will leave walking routes and handle hoses and water connections at the end of the visit. Before arrival, move the belongings covered by your agreement, arrange water access, and keep pets away from the work area.

Use the precipitation chart as historical background for the drainage discussion. NWS reports a 1991–2020 annual normal of 46.24 inches. The other examples come from its wettest-years ranking, so they do not represent typical years or predict conditions on your washing date. Base the appointment on the forecast and your property's drainage. [4]

Frequently Asked Questions

How can I compare prices without a citywide estimate?

Compare written quotes for your property. Give each provider the same scope and photographs, then check whether their totals include preparation, stain treatment, runoff handling, and cleanup. Request a separate price for optional work so you can compare the core job.

Does historic designation require approval for every wash?

Charleston identifies design review for properties within the original East End Historic District, but its overview does not say that every washing job requires approval. Check your address against the district boundary and obtain guidance about the specific treatment before authorizing it. [1]

Is a street drain an acceptable wash-water destination?

Confirm the applicable requirements before allowing that discharge. WVDEP distinguishes MS4s from sewage treatment plants and lists Charleston's system. Its overview does not specify disposal requirements for your individual job. Have the provider identify a disposal destination and explain any confirmation they need. [2]
