When is the best time to build a deck in the Capital Region?

Around the Capital Region, decks get built from late spring through fall, once the ground has thawed, footings can be poured, and stain will cure. But the time to start is the winter before. Design, drawings and a building permit all take weeks, and the people standing on a finished deck in June are the ones who started talking about it in January.

A short season with a lot packed into it

Our building season is short. Frost hangs in the ground well into spring, snow can show up in late October, and every outdoor project in Saratoga County wants the same warm months in between. A deck runs into the weather at three points.

Footings come first. They're holes in the ground filled with concrete, and frozen or soaked soil makes that hard to do right. Your town or city building department sets how deep footings have to go where you live, and that depth is picked to get them below the frost line. Ask them. Don't go by a number you read for some other part of the country.

Framing and decking can go up in cooler weather, but rain and snow slow it down and leave the lumber wet.

Finishing a wood deck needs dry boards and temperatures inside the range printed on the can, overnight included.

Winter: decide what you want

Use the cold months to figure out the deck. How will you use it? How many people should fit around the table? Where does the grill go, and where should the stairs come down into the yard? Measure the space and mark where the doors, windows, dryer vent and any utilities are on that side of the house. Pick wood or composite now, too; our guide to composite vs wood decking lays out the tradeoffs.

Most new decks need a building permit, and the application generally wants a drawing with the size, height, footings, framing and guards. Get that done in winter and the permit can be in hand before the frost comes out.

Spring: everybody calls at once

When the frost is out and the ground dries, footings can go in. Spring is when the phone rings most, so the earlier in the year you start, the easier it is to get on a schedule. Rain is what holds things up at this stage. A week of it in May can push footings back by more than a week, because the holes fill with water and the ground has to dry again.

Spring is also when to look over the deck you already have for winter damage. Our spring home inspection after winter has the deck items on it.

Summer: good building weather, with one catch

Long days and dry stretches are good for framing and finishing. If you want the deck for a July party, work back from that date and you land on a winter start. Calling in June for a July deck doesn't work.

The catch is heat. Stain brushed onto hot boards in afternoon sun dries too fast and leaves lap marks, so we'd stain in the morning or on an overcast day.

Fall: the season people overlook

September and October are often the nicest months to work outside in the Capital Region. It's cooler, the air's drier, and there's often less rain than in spring. Build in the fall and the deck is ready on the first warm Saturday next year, without fighting the spring rush.

The limit is the calendar. Concrete and finish work have to wrap up before the nights turn cold for good, so plan a fall deck by late summer.

After the first frost, some work keeps going: framing on footings that are already in, repairs, swapping out rails, work on a covered porch. New footings and staining are hard to do well once the cold settles in. Fall is also when to get an older deck ready for snow, which is on our fall home maintenance checklist.

Treated lumber has to dry before it takes stain

This catches people off guard. New pressure-treated boards often show up wet from the treatment and need time before they'll take stain. Sprinkle some water on them. If it beads, they're not ready. If it soaks in within a few minutes, they are. That can take anywhere from a few weeks to a few months, depending on the lumber and the weather.

So a treated deck built in late spring can generally get stained in late summer or early fall. One built in late fall may wait until the next spring for its first coat. The stain maker's instructions are the final word. Composite and PVC skip all of this.

Permits, inspections and the historic district

How long a permit takes varies by town and by time of year, so ask the building department early how long reviews have been running. Inspections, typically of the footing holes before the concrete goes in and of the finished framing, get scheduled around the work. Our post on whether you need a permit in Saratoga Springs explains how to work it out and why skipping a permit can come back to bite you when you sell.

In the Saratoga Springs historic districts, a deck people can see from the street may also need Design Review Commission approval. That review runs on its own schedule. One more reason to start in winter.

Tearing out an old deck first

Replacing a worn deck adds demolition, and demolition turns things up: a rotted ledger, footings that have failed, water damage on the house wall behind the old deck. Plan for that, and agree up front on how those finds get handled in writing, and the job keeps moving. If you're not sure the old one needs to go, read signs your deck needs to be replaced before you plan the season around it.

You also lose the deck while the work's going on. If it's the only way out of a kitchen door, plan for a temporary step or another exit, and keep that door locked while there's a drop outside it.

Frequently asked questions

Can a deck be built in winter in upstate New York?

Some of it. Framing, decking and rails can go on in cold weather if the footings are already poured, though snow and short days slow things down. New footings and staining are hard to do well in freezing weather, so most new decks get scheduled between spring and fall.

How far ahead should I plan a summer deck?

Start in winter if you want to use it by midsummer. That leaves time for design, a permit and a spot on the schedule before the spring rush. Start talking in late spring and you're probably looking at a late summer or fall build.

When should a new pressure-treated deck be stained?

When the boards are dry enough to soak up water, which can be a few weeks to a few months after they go down. Sprinkle water on them. If it beads, wait. If it soaks in, use the product the stain maker recommends.

We'd rather plan a deck in February and build it in May than rush one into October. See our deck, stair and railing projects for work around the Capital Region.
