Window cleaning in Austin, TX: Plan Your Service

Define the job before comparing quotes

Start with a room-by-room list of the windows you want cleaned. Specify inside, outside, or both, then name any glass doors or other glass you want included. Send photographs of upper-floor windows, tight side yards, and windows above roofs. Ask the provider to confirm the count and explain its pricing unit.

Name screens, tracks, and sills as separate scope items. Ask whether the crew will remove and reinstall screens, wash them, or wipe them in place. For tracks, describe whether you want loose debris removed or a more detailed clean. Get the agreed tasks in writing so you can compare offers without guessing what each provider includes.

Identify paint specks, adhesive, or stubborn spots in your photos. Ask the cleaner to inspect those areas and quote any additional treatment before starting. Share the manufacturer's care instructions if you have them, and request approval before the crew uses a scraper or stain-removal product.

Compare the complete price

Ask each provider for the service subtotal, applicable tax, and final payable total. The Texas Comptroller names washing windows among taxable cleaning services and instructs providers to collect state tax plus applicable local taxes on the amount billed. Do not apply residential remodeling tax assumptions to a window-cleaning quote. [4]

Request separate amounts for the base clean, screen and track work, stain treatment, and any access equipment. Ask whether the provider needs an inspection before fixing the price. If a bidder leaves part of the scope open, request a written change-approval process rather than accepting an undefined additional charge.

Use property-specific written quotes for your budget. Ask for a one-time price before discussing repeat visits, then compare the scope and terms of both arrangements. Choose a repeat schedule after you see the result and decide how often you want the glass cleaned.

Discuss rinse water and existing spots

Austin Water's 2025 report lists total hardness from 70 to 126 ppm as calcium carbonate, with an average of 93 ppm. The utility defines hardness as dissolved calcium and magnesium. Use that local context to ask how the cleaner will rinse and finish the glass, especially if you have concerns about spotting. [3]

Ask the provider to separate routine cleaning from treatment of existing marks. Request a test on a small area before approving additional stain work, and agree on the expected result. The utility's water measurements do not establish the cause of a particular spot or prove that a cleaner can remove it. [3]

Check the plan for bundled pressure washing

Ask whether the quote includes pressure washing of walls, paths, or other surfaces. Austin Water's restriction page, checked on October 12, 2026, identifies Conservation Stage restrictions in effect since September 2, 2025. It prohibits wasting water and requires commercial power and pressure washing equipment to meet efficiency requirements. Ask the contractor to check the current rules before the visit. [1]

For that pressure-washing work, ask where the contractor will collect and dispose of wash water. Austin Water prohibits discharge to storm sewers when wastewater contains pollutants or cleaning compounds and has not received treatment before entering the environment. The utility also restricts disposal through onsite cleanouts, manholes, or toilets unless the site has its authorization and an appropriately sized sand/oil interceptor. [2]

Ask the operator to confirm its disposal plan with Austin Water Utility Compliance Services at 512-972-1060, option 5, before beginning operations. These published disposal instructions address power washing and mobile car washes. For a glass-only hand-cleaning job, ask the provider to describe its method rather than assuming the pressure-washing instructions define that service. [2]

Prepare access and agree on completion

Before booking upper-floor work, ask how the crew will reach the glass and request proof of insurance for the proposed work. Share access restrictions, locked gates, and any building-management requirements. For a condo, confirm which exterior surfaces you may arrange to have cleaned before accepting a quote.

Clear the agreed work areas, move fragile items from sills, and arrange a place for pets during indoor work. Tell the crew about damaged screens, loose frames, and windows you do not want opened. Ask who will move furniture and whether the crew needs access to your water supply.

Agree on a finish inspection and a process for reporting missed areas. Walk through the included windows with the cleaner, check screen placement, and review any marks the crew could not remove. Ask about weather rescheduling and return-visit terms before the appointment.

Frequently Asked Questions

Does Texas charge sales tax on home window cleaning?

The Texas Comptroller lists washing windows among taxable cleaning services. Ask the provider to include state and applicable local tax in the final total you compare. [4]

Do Austin's lawn-watering days control my cleaning appointment?

The published watering schedule addresses irrigation. For a cleaning package that includes pressure washing, check the separate equipment-efficiency requirements and prohibition on wasting water with the contractor before booking. [1]

Can the contractor empty pressure-wash wastewater into my toilet?

Austin Water prohibits that disposal at the site being cleaned unless the site has its permit and an appropriately sized sand/oil interceptor. Ask the operator to confirm its collection and disposal plan before work begins. [2]

Should I pay extra for spot removal?

Ask for an inspection, a test area, and a separate price before approving treatment. Have the cleaner explain the expected result and any marks it expects to remain. Avoid agreeing to an open-ended stain-removal charge.
