Is sealing your concrete worth it in Indianapolis?
Concrete sealing in Indianapolis, IN means putting a sealer on your driveway, walk, patio or garage floor so the concrete takes in less water and less of the salt in winter deicers, which helps keep the surface from pitting and flaking off.
Most calls start with a driveway, front walk or garage apron that soaks up water and has started to pit after a few winters of salt. The price turns on how big the area is, how much cleaning and crack repair it needs first, and whether old sealer has to come off before new sealer will take. The schedule turns on the concrete and the weather, since new concrete has to cure before it's sealed and the sealer needs a dry, mild stretch to go on. I look at it in person and write up what it needs, and if you'd rather have a full coating than a clear seal in the garage, we do garage floor coatings too.
How do you know your concrete needs sealing?
Pock marks and flaking
Small pits, or patches where the top of the concrete has flaked away, usually show up after winter and mean water and deicer have worked into the surface and frozen there. It spreads a little more every winter, and once it's deep, sealer alone won't fix it.
Water soaks right in
If your concrete goes dark after rain and stays dark instead of beading up, there's no sealer left on it or there never was. Every thaw, it's soaking up salty water from the street and your boots.
Old sealer turning white
Cloudy white patches or peeling film on concrete that was sealed before usually mean too much sealer went on or moisture got trapped under it. New sealer won't hold on top of that, so the bad layer has to come off first.
How we handle concrete sealing
Sealer only does its job if it goes on right, on concrete that's ready and in dry weather, so that's the order we work in. I check the concrete first to make sure it's cured, sound and dry, then we clean it, take off any failing sealer and fix cracks and damaged spots so we're not sealing over a problem. We wait for the right weather and put the sealer on in an even coat rather than a heavy one, because a heavy coat is what turns white and peels later.
Sometimes sealer isn't enough. If the top of your slab has already flaked away in patches, concrete resurfacing and overlays gives you a fresh surface worth sealing, and if a basement or garage floor has dips and low spots, self-leveling concrete and overlays flattens it out first. I'll tell you at the estimate if your concrete needs one of those before sealer will do any good.
Penetrating sealer for salted concrete
This kind soaks into the concrete instead of sitting on top, so it keeps the natural look with no added gloss and keeps the grip your driveway already has. It suits driveways, walks and garage aprons that see deicer every winter.
Film-forming sealer for covered concrete
This kind dries into a film on the surface and can add some sheen, which some people want on a covered patio or an indoor floor. One maker notes that some of these wear from foot traffic, snow removal equipment and deicers and aren't meant for long-term winter protection, so they fit sheltered concrete better than a salted driveway.
Resealing concrete sealed before
If your concrete was sealed years ago, I check what's on it first, because new sealer doesn't bond to old sealer that's peeling or chalky. Sometimes it's a good cleaning and a fresh coat, and sometimes the old layer has to come off.

I look at the concrete
I check what's on the surface, how it's holding up and whether it needs repair before sealer, then write up the estimate. It tells you what the concrete needs, which sealer I'd use and what it costs before anything starts.
We prep and seal it
Our crew cleans the concrete, fixes what needs fixing and puts the sealer down on a dry day. If rain moves in, we move the date, because sealer that gets rained on too soon doesn't do its job.

Concrete sealing, prep and repair in Indianapolis
In Indianapolis, the city's Department of Business and Neighborhood Services licenses the people and businesses doing construction work, except in Lawrence, Beech Grove, Speedway and Southport. City code also says anyone doing construction, land alteration, driveway or excavation work has to be a listed contractor. When you're comparing quotes on a driveway inside the city, that's the office that licenses the crew, and it's worth knowing before anyone starts on your concrete.
Marion County Public Health says only rainwater, snow and ice melt, lawn watering and sump pump water typically belong in a storm drain, and anything else is treated as an illicit discharge, so we keep wash water and sealer out of the drain at the end of your driveway. We see the same salt-worn driveways and garage aprons on jobs in Fishers and Greenwood, and we handle them the same way.
Questions about concrete sealing in Indianapolis
How much does concrete sealing cost per square foot in Indianapolis?
Professional concrete sealing, labor and materials included, usually runs about $1.50 to $2.50 per square foot across the US. That's the going rate, not our price. Where your job lands depends on how much cleaning and repair the concrete needs and whether old sealer has to come off, and the estimate gives you your own number.
Which concrete sealer holds up best against road salt?
A concrete industry guide rates silane or siloxane penetrating sealers highest for resisting deicer and freeze and thaw damage. If you salt your driveway in winter, that's the type to weigh first when you compare quotes. I'll tell you which one I'd use on your concrete when I come out.
How long does concrete sealer last on a driveway?
One maker's bulletin says penetrating sealers typically last 5 to 10 years when they're properly applied. The way it goes on matters as much as the product you pick, which is why most of our time goes into prep and picking the right day.
What is the best time of year to seal concrete in Indianapolis?
The warmer, drier months between the last spring freeze and the first fall freeze are the best time, because one maker's penetrating sealer goes on only when the air is 50 to 90°F, humidity stays below 85% day and night, and no rain is expected for 24 hours. The National Weather Service puts the average last freeze in Indianapolis at April 17 and the average first freeze at October 26. That same maker's sealer goes on out of direct sunlight, so ask any crew what time of day they plan to apply it.
How soon can I drive on a sealed driveway?
One maker says to wait 24 to 48 hours before cars go back on it, and at least 4 to 6 hours before light foot traffic. Those times are based on 70°F and 50% humidity, so a cooler or damper day can mean waiting longer.
How long does new concrete have to cure before you seal it?
One maker's instructions call for new concrete to cure at least 28 days before it's sealed. If you've had a fresh pour, we schedule the sealing after that wait. That maker also advises skipping deicing salts such as sodium chloride or calcium chloride during the first winter.
