Poured Concrete
This is your standard poured slab, whether it is a back patio or the pool deck around the water. An algaecide clears the growth, a surface cleaner washes the slab down, and after it dries the penetrating sealer goes on.


Algae and other green growth can build up on concrete patios and pool decks, while winter road salt adds to the wear. Sean’s Property Services treats the growth with algaecide, pressure washes the concrete, then applies a water-based penetrating sealer once the surface is completely dry. Call us at 978-995-3110 for a free estimate on your patio or pool deck.
We seal two kinds of concrete, and both get the same treatment: clean it, let it dry, seal it. Here is how we handle each one.

This is your standard poured slab, whether it is a back patio or the pool deck around the water. An algaecide clears the growth, a surface cleaner washes the slab down, and after it dries the penetrating sealer goes on.

Stamped concrete gets the same work as a poured slab. The algaecide and the surface cleaner lift the growth, and the same penetrating sealer goes on once it dries.
A seal job is only as good as the crew doing it. Here is what you get with us.
We use a water-based penetrating sealer, and that choice matters down the road. Because it is our own water-based product, we can come back later, pressure wash the concrete, and reseal it. You are not locked into a one-time job with a sealer nobody can touch again.
We did not learn sealing off a video. A sealer manufacturer flew us out for hands-on product training, and we follow those instructions to the letter. Sealer put down the wrong way fails early, so we do it the way the people who make it told us to.
Sealer over damp concrete is money wasted, so we wait. A patio that still holds moisture underneath will not take a seal, which is why this runs as a job of more than one visit. We would rather come back than rush a seal and watch it fail.

Concrete sealing takes a few visits. We quote it, book it, clean it, let it dry, then seal it. Here is each step.
Call, text, or send us the form. For most jobs we look up your property and price it off the square footage. We will ask for a couple of photos if we need them. Want us to come look in person? We will. The estimate lands in your inbox for you to approve on your own time, no pressure either way.
Accept the estimate and we get you on the schedule right away. You get a text and email with your date and a one-hour arrival window. We send a reminder the day before and the day of, then an on-the-way message with an ETA. The crew knocks when they get there.
First we put down an algaecide to kill the organic growth in the concrete. Then we pressure wash the surface with a surface cleaner. We run off your outdoor spigot for this.
Now the concrete dries. No sealer touches it until it is dry all the way through. That is the reason this job runs across a few visits instead of start to finish in a day.
Once it is dry, we spray on the water-based penetrating sealer. It soaks down into the concrete rather than sitting on top of it.
The crew marks the job finished, lets you know it is done, and packs up. Your invoice follows after. If anything about the work is not right, we want to hear about it, and we will take care of it.
Concrete sealing is priced by the square footage of the surface, and your exact number comes with your free estimate. A bigger patio or pool deck costs more than a small one. The price already covers the clean, the dry time, and every visit a seal job takes.
Priced the same as paver sealing. Most jobs average around $1,400.
Call us if something about your sealed concrete is not right. We will look at a photo first and come out if we need to. We figure out whether it came from our work or from something that was already there. If it is on us, we fix it. 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. This covers our workmanship, not the normal wear a surface picks up over the years.
No. On concrete we use a penetrating sealer, not a film that sits on top. It soaks in, so it won't make your patio slippery. We don't offer a wet-look finish on concrete, only the clear penetrating seal that absorbs into the surface.
We wait for dry weather. The concrete has to be completely dry before the sealer goes on, so rain pushes the schedule rather than changing the work. Once the surface is dry again, we come back and finish the next visit.
No. Everything we do is outside, so we never need to come inside your home. We do need access to an outdoor spigot. The crew knocks on arrival and lets you know when they are done. Because a seal job takes a few visits, you hear from us before each one is booked.
No. Concrete sealing is not part of the ten-percent discount for booking three or more services. That discount covers our cleaning services, like a house wash, roof cleaning, windows, gutters, solar panels, deck or fence cleaning, concrete cleaning, and rust removal. Sealing is priced on its own.
