Multi-Building Apartment Complexes
Several buildings on one property, washed one building at a time and top down. We settle the full scope with you before the first hose comes out. Then we move building to building until the property is done.


Algae, moss, and lichen can build up on apartment buildings, especially on north-facing vinyl siding that stays shaded and damp. Sean’s Property Services treats the growth with a soap and algaecide mix, then rinses the siding with plenty of water instead of high pressure. Call us at 978-995-3110 to discuss cleaning your apartment buildings.
We work apartment properties one building at a time, and we set the scope with the property manager before anyone picks up a hose. Two kinds of property make up most of what we clean.

Several buildings on one property, washed one building at a time and top down. We settle the full scope with you before the first hose comes out. Then we move building to building until the property is done.

One long building with a lot of units under a single roofline. We have washed a building of about 45 units this way. It is still one building to us, worked top down from one end to the other.
Three things matter when you hand a complex to a crew. Can they handle the size. Will they hold the quality. And is the paperwork in order.
We are set up for large exteriors and multi-building complexes. Each building gets the same commercial building washing we bring to any large exterior. We run commercial pressure washers and a hot-water unit, work off multiple crews, and arrive in fully wrapped trucks with an enclosed trailer. The scale of a complex is the kind of job the equipment is built for.
Every building on your property gets the quality we give a homeowner's house. Nothing about a commercial account means a lighter wash. You get the work done right, you can report it done, and you can move on to the next thing on your list.
We are fully licensed and insured, with general liability, an umbrella policy, workers' compensation, and commercial auto. A W-9 and certificate of insurance are ready on request. That is the paperwork you need in hand before a crew sets foot on the property, and we have it waiting.

Here is how a complex wash goes with us, from the first walkthrough to the invoice at the end.
Call, text, or use the form, and our office usually picks up. For a commercial property we come out and walk it in person unless the job is straightforward. We work out a price for each building on the property, and the estimate is free.
We agree with you on the scope: which buildings, and which add-on areas go in. Whatever documents your office needs to put us on the property come over on request. If a building has structural or electrical trouble that water would make worse, we flag it here before anything starts.
We send the estimate over to accept online, and accepting it books the job right away. You get a text and email with your date and a one-hour arrival window. Then come reminders the day before and the day of, plus an on-the-way message with an ETA.
We let you know when we have arrived and connect to water. Then we check each building before any mix goes on. We look for open windows and anything leaning on the siding. We cover or tape exposed outlets and electrical boxes. We note painted doors that could stain.
We apply an algaecide and soap mix, with the strength matched to how dirty the building is. The mix does the work on the growth, and we rinse the vinyl down with a high flow of water at low force. Concrete and brick are pressure washed where that is what the surface needs. Then we move to the next building.
Any stairs, walkways, or parking areas you put in the scope get cleaned with a surface cleaner once the buildings are done.
We mark the job finished and let you know. The crew rolls the hoses and packs up. The invoice follows, and commercial customers may be on net terms. If anything is not right because of something we did, we come back.
We price apartment work per building, by square footage, and we sanity-check that number against the unit count. The final figure comes from the walkthrough estimate.
From $600 per building. That is the starting point for a single building. It climbs with square footage and with how much growth and soil there is to clear, so larger buildings run higher. Add-on areas are priced on top.
Our building price covers the building. Stairs, walkways, parking areas, and dumpster pads are easy to add, just tell us what you want in the scope and we'll price it. A covered parking structure is a different job from open flatwork, and we take those on under parking garage cleaning. Flatwork like this gets cleaned with a surface cleaner on the same visit, once the buildings are finished.
We stand by our work. If something isn't right because of something we did, we'll come back and make it right, no runaround. Send us a photo first and we will take a look, come out ourselves if we need to, and figure out what happened. When it is on us, we fix it. That covers our workmanship, not the normal wear a building picks up over the years.
Most buildings take hours, not days. One building of about 45 units ran about four hours. Total time scales with how many buildings are on the property, so a multi-building complex is planned across the day or days it needs.
Yes, on request. We can work out a monthly, quarterly, or annual schedule with you, set up case by case for your property. If you also manage an HOA community, we handle exterior cleaning for HOA communities on the same kind of schedule. We do not sell packaged tiers; it is an arrangement we build around what your complex actually needs.
Not where water would make the problem worse. Crumbling concrete, a roof leak reaching an electrical panel, or exposed wiring are the kinds of trouble we will not wash over. We check for it at the walkthrough and tell you straight if we have to pass on a building.
Yes, commercial customers supply the water for the job. If that is a problem, we can bring water for an added charge. We will sort out which it is during the walkthrough so there are no surprises on the day.
