Window Cleaning in Charleston, SC: Plan Your Job
For Window Cleaning in Charleston, choose a provider who gives you a written scope, explains how the crew will reach the glass and confirms who handles any sidewalk permissions. Ask for separate prices for interior glass, exterior glass, screens, tracks and stain treatment. If equipment will occupy a city sidewalk, resolve access before booking: Charleston requires permits for sidewalk work or blocking. [1]
Get a quote you can compare
Send each provider the same photos and description. Include the glass you want cleaned, the floors involved and views of the ground beneath upper windows. Point out enclosed porches, fixed panes, divided panes and windows behind furniture. Ask the provider to confirm the count in writing before you accept the price.
Request an itemized scope rather than relying on the phrase whole-house cleaning. Specify interior and exterior surfaces, screen removal and washing, tracks, sills and frames. Ask whether the crew will reinstall screens and whether you must remove them beforehand. Have the provider list exclusions and obtain your approval before adding work.
For price planning, use a written quote for your property. Ask for the total, any minimum visit charge, access costs and optional treatments. Compare one-time and recurring offers only after matching their scope. Keep any recurring-service commitment separate from your approval of the first visit.
Settle access and credentials before booking
Ask how the crew plans to reach each upper window and where it will place equipment. Share photos of narrow passages, steps, planting beds and nearby pedestrian routes. Request proof of insurance and ask the provider to confirm coverage for the proposed work. For difficult access, request a site assessment before agreeing to a final price.
The City of Charleston requires an annual business license for businesses operating within its limits. Treat that as a separate check from insurance and the crew's proposed cleaning method. Ask for the business name on the quote, license and insurance documents so you can compare them. [2]
For work beside a city sidewalk, ask the provider to map the equipment footprint and pedestrian route. The city lists sidewalk blocking among engineering-permit examples and directs permit questions to its Engineering Division at 843-724-3782. Confirm who will contact the city and include any agreed permit costs in the quote. [2]
Agree on water use and stain treatment
Ask whether the crew needs your outdoor spigot or brings its own water. Charleston Water System recommends a hose-bib vacuum breaker on each outside spigot to prevent water from being siphoned back from a hose into household plumbing. Check the planned connection before the visit; ask a plumber or the utility if you need help assessing it. [3]
Charleston Water System reports average water hardness of 58.4 ppm, or 3.4 grains per gallon, and describes its water as moderately soft. Its discussion of dish spotting explains that minerals remain after water evaporates. That guidance concerns dishes, so do not use it to diagnose window stains or choose a window-cleaning chemical. [3]
Send close-up photos of persistent marks and ask the cleaner to assess them before quoting treatment. Request a separate price and an explanation of the proposed method. Identify any known glass coatings or manufacturer care instructions. Ask the crew to test a small area with your approval before treating a larger surface.
Plan the visit and weather fallback
Agree on an arrival window, whether you need to be home and how the crew will enter enclosed areas. Move fragile items from sills, clear the agreed indoor workspace and secure pets. Tell the provider about windows that stick, damaged screens and existing marks before work begins.
Ask the provider to explain its weather cancellation and rescheduling policy. At Charleston International Airport in North Charleston, the National Weather Service recorded 3.54 inches of precipitation and seven days with thunderstorms in September 2026. Those observations describe a past month at the airport; use the forecast and the provider's access assessment for your appointment. [4]
Before the crew leaves, review the agreed surfaces together. Check screen placement and inspect any area that received stain treatment. Ask the cleaner to identify marks that remain and record any follow-up agreement. Avoid accepting extra treatment during the visit without understanding its price and proposed method.

Local details that affect your job
City sidewalk blocking needs an access plan
Charleston's Infrastructure Management Division states that city sidewalks need a permit for work or blocking. It directs applicants to send pedestrian detour documents to [email protected] when a job requires sidewalk blocking. The city also discusses maintaining 36 inches of clearance with ADA compliance; do not treat that clearance as a permit exemption. Before booking, have the provider confirm the required permit and pedestrian arrangement with the city. [1]
Check the outdoor hose connection
For a visit using your outdoor water supply, check the spigot connection with the provider. Charleston Water System recommends hose-bib vacuum breakers on outside spigots to protect household plumbing against back-siphoning from hoses. Ask the crew how it will connect its equipment and resolve any uncertainty before it starts using your water. [3]
Match the arrangement to your property
| Your situation | Before accepting the quote | Ask the provider |
|---|---|---|
| Accessible glass with routine cleaning requested | Define surfaces and window count | Does the total include screens, tracks and reinstallation? |
| Upper windows or restricted ground access | Request an access assessment and insurance documents | How will the crew reach each window and protect the workspace? |
| Equipment may occupy a city sidewalk | Have the provider confirm the city's permit and pedestrian requirements | Who handles the application, detour documents and associated costs? |
| Crew plans to use your outdoor spigot | Review the hose connection and the utility's vacuum-breaker guidance | What water supply and connection will you use? |
| Persistent marks or known glass coatings | Request an assessment and separate treatment price | What method do you propose, and can you test an agreed area? |

Frequently Asked Questions
Does the cleaner need permission to block a sidewalk?
Charleston requires permits for city sidewalk work or blocking. Ask the provider to confirm the arrangement with Engineering before booking. Include responsibility for applications, pedestrian access and costs in your agreement. [1] [2]
Does a city business license replace an insurance check?
Check both. Charleston requires businesses operating within the city to hold an annual business license. Request insurance documents as a separate hiring step and ask about coverage for the work and access method you are approving. [2]
Will ordinary cleaning remove the spots on my glass?
Ask the cleaner to assess the marks before promising a result or quoting treatment. Charleston Water System's mineral-spotting explanation concerns dishes and does not establish the cause of window marks. Request a separate treatment proposal and an agreed test area. [3]
What should I arrange before the crew arrives?
Confirm entry, water access, equipment placement and any screen-removal responsibilities. Clear the agreed workspace, secure pets and identify existing damage. Keep the written scope available for a walkthrough when the crew finishes.
