Pressure Washing in Boston, MA: Plan and Hire
Arrange Pressure Washing in Boston by getting a property-specific quote that names the surfaces, cleaning method, water supply and disposal plan. Before booking, confirm permit requirements for abrasive blasting or chemical cleaning and check whether landmark review applies to masonry cleaning. Assign application responsibilities in writing and choose a start date after required approvals. [1] [2]
Define the surfaces and result before comparing quotes
Send each bidder the same photographs and surface list. Identify the material if you know it, describe the staining and mark areas you want excluded. Request a written description of the pressure, cleaning products, application method and rinse procedure. Have the contractor describe the treatment proposed for each surface rather than quote an undefined house wash.
Request a test area for masonry, painted surfaces or an unfamiliar finish. Agree on its location and inspect the result before authorizing the remaining work. Have the contractor photograph existing loose mortar, peeling paint and damaged joints, then explain whether they recommend repairs before cleaning. Describe the result you expect and ask which stains the contractor excludes from that promise.
Obtain a property-specific total that includes setup, products, equipment and cleanup. Request separate amounts for access equipment, application work and wash-water collection if the contractor proposes those services. Compare exclusions and change-order terms alongside the price. Confirm who can authorize extra work and how the contractor will price it.
Confirm the cleaning method with the city
Boston's Air Pollution Control Commission describes abrasive blasting as cleaning with water, sand or other materials under high pressure, and chemical cleaning as using chemicals and water. The city requires a permit for projects requiring either method. Give commission staff the proposed method and products when you ask about your job. [1]
Resolve the permit question before setting a firm date. Name the person who will prepare the application, pay applicable fees and provide approval documentation. If the contractor changes the method after inspecting the property, confirm that change with the commission before authorizing treatment. Use the method description in your agreement rather than relying on the advertised service name.
Check landmark review before masonry cleaning
Check whether your property is an individual landmark, lies within a historic district, or is under review or awaiting a landmark designation decision. The Boston Landmarks Commission includes masonry cleaning among design-review projects and also reviews proposals for properties awaiting designation. Historic district commissions conduct their own review, so confirm which body handles your address. [2]
For designated properties, consult the property-specific study report before choosing a treatment. The commission reviews exterior changes to design, materials or appearance and requires approval of changes at a public hearing before work starts. Share the proposed cleaning method with staff and have the contractor account for the applicable standards in the quote. [2]
Check current hearing dates and deadlines before scheduling the contractor. The commission describes fourth-Tuesday design-review hearings as its usual schedule, while its 2026 calendar lists one combined meeting on December 8. Staff must receive an application they determine complete 15 business days before the hearing for agenda placement. Confirm the current schedule with staff before committing to a cleaning date. [2]
Agree on drainage, water supply and access
BWSC reports that separate storm drains serve approximately 80% of Boston and that its stormwater system discharges into receiving waters around the city. Have the contractor trace the drainage route from the work area. Identify nearby drains and agree on how the contractor will contain and collect wash water, then confirm the proposed disposal route with BWSC. [3]
Confirm whether the contractor will use your outdoor tap or bring water. Request expected consumption and any separate supply charge. BWSC calculates water and sewer charges using consumption, billing-period length and applicable usage levels. The chart shows selected residential water rates for 2026. Use those rates to discuss water supply; obtain a separate quote for cleaning and avoid treating the chart as a calculation of your added bill. [4]
Agree on who will move furniture, planters and vehicles. Point out outlets, vents and known leaks, and arrange access through gates. Request proof of insurance and a written process for handling damage. Include payment and cancellation terms, then plan a walkthrough to inspect the listed surfaces before closing out the job.

Local details that affect your job
Method-based permit questions
Contact Boston's Air Pollution Control Commission at 617-635-3850 with the proposed cleaning method and products. The commission regulates abrasive blasting and chemical cleaning of buildings and provides a permit application. Confirm how staff classify your proposed work before booking and name the application contact in your agreement. [1]
Landmark status and application timing

The commission describes fourth-Tuesday design-review hearings as its usual schedule; its 2026 calendar lists December 8 as one combined meeting. Confirm current dates and allow for staff's complete-application deadline of 15 business days before the hearing. [2]
Confirm the wash-water destination
BWSC operates storm drains that discharge into local receiving waters. Before accepting a plan involving a street drain or sewer, have the contractor identify the drainage route and confirm disposal arrangements with BWSC. Put containment, collection and disposal responsibilities in the quote rather than leaving them for the crew to decide on arrival. [3]

Frequently Asked Questions
Does pressure washing require a Boston permit?
Boston requires a permit for projects requiring abrasive blasting or chemical cleaning. Give the Air Pollution Control Commission the contractor's actual method and products so staff can address your proposed work before you book. [1]
Should I check landmark status before cleaning masonry?
Yes. BLC lists masonry cleaning among design-review projects and reviews proposals for designated properties and properties under review or awaiting designation. Confirm the review route with staff, including any separate historic district review, before setting a start date. [2]
Can the contractor direct wash water into a street drain?
Confirm the disposal route with BWSC before agreeing to it. BWSC's stormwater system discharges into local receiving waters. Require the contractor to identify drainage and explain containment, collection and disposal in the work plan. [3]
Do the chart's rates tell me what the job will cost?
No. They show selected BWSC residential water rates effective during 2026. Obtain a cleaning quote for your property and ask about water supply. BWSC bases utility charges on consumption, billing-period length and usage levels, so these water-only rates do not establish your added bill. [4]
