Homeowners ask us this in January and again in July, usually with some worry behind it. Someone told them you should never put wood down in the summer. Or their neighbor’s floor gapped over the winter, and now they’re convinced there’s a right month and a wrong month and they’re about to pick wrong.
Short version: for most Raleigh houses, the month matters less than whether the HVAC is running. There are real cases where timing changes the outcome, though. And there’s a separate scheduling problem that has nothing to do with wood science and everything to do with everyone wanting the same six weeks.
Here’s how we think about it.
The thing that matters is indoor humidity, not the month
Wood takes on moisture from the air around it and gives it back when the air dries out. It swells and shrinks doing that. The goal of a good install is to put the boards down at roughly the moisture content they will average once they live in your house, so the seasonal movement gets split evenly in both directions instead of all going one way.
The NWFA target for that environment is 60 to 80 degrees and 30 to 50 percent relative humidity, which you can read more about in Hardwood Floors Magazine’s breakdown of acclimation conditions. That’s the indoor number. Outdoor humidity in Raleigh runs from about 61 percent in April to 78 percent in August, but your air conditioner spends the summer pulling that down and your furnace spends the winter drying it out further.
So a conditioned Raleigh house sits inside a much narrower band than the weather does. Which is why a house with working HVAC can take a floor in pretty much any month.
The houses where the calendar starts to matter are the ones that aren’t conditioned yet, or aren’t conditioned consistently:
- New construction where the HVAC isn’t commissioned yet
- Renovations running with windows open or a door off
- Additions that are framed and dried in but not tied into the main system
- Vacant houses between owners with the thermostat off
- Anything over an open crawlspace that has never been encapsulated
If your project is one of those, keep reading. If your house is occupied and the HVAC works, book whatever month suits you and skip down to the scheduling section.
Month by month in Raleigh
| Window | How it treats wood | What we watch for |
|---|---|---|
| January to February | Driest indoor air of the year. Boards go down near their annual minimum moisture. | Floors put down now can push tight and cup or crown by August if the house runs humid. Worth adding humidity in a very dry house. |
| March | Conditions swing hard week to week. Heat on Monday, windows open Thursday. | Acclimation readings wander. We take more of them. |
| April to May | Close to the middle of the annual range. Outdoor humidity bottoms out in April. | Not much. Easiest stretch of the year. |
| June to August | Highest outdoor humidity, peaking near 78 percent in August. | Boards laid at their wettest can leave winter gaps. Site finish coats also cure slower in humid air. |
| September | Still warm and humid early, settling by the end of the month. | Late September is better than early September. |
| October to early November | The other good window. Stable, mild, low swing. | Not much. Books up fast. |
| Late November to December | Heat running, air drying out, plus holiday deadlines. | Same dryness issue as January, compounded by everyone wanting it done before company arrives. |
If you want one answer: April into May, and late September into October. Spring and fall have the least distance between what’s happening outside and what your HVAC is doing inside, so the acclimation target and the environment the floor ends up living in are close to the same thing.
The ones I’d push back on are late June through August for an unconditioned house, and December for anyone hoping to have it cured before a holiday. Not because the floor will fail. Because the margin gets thin and something usually slips.
Refinishing has a different calendar than installation
People assume these work the same way. They don’t.
A refinish isn’t putting new wood into your house, so acclimation isn’t the question. Cure time is. Water based finishes go down and dry fast, but humid August air slows the cure between coats and a three to four day job can stretch to five. Oil based takes longer anyway and puts more smell in the house, which is worse at 95 degrees when nobody wants the windows open.
Winter is quietly one of the better times to refinish. Dry indoor air means faster recoats and a tighter schedule. The tradeoff is you can’t air the house out easily, so if someone has asthma or there’s a baby in the house, say so and we’ll pick the finish system around that. We cover the dry time and the livability side in more detail in our post on dustless refinishing in Raleigh, and if you are still deciding whether you need one at all, refinish or replace walks through how to tell.
Why our calendar fills when it does
This part has nothing to do with wood.
Two things drive our Raleigh calendar. Spring and fall are when people list houses, close on houses, and wrap up renovations, so April, May, and October carry the heaviest demand every year without fail. Then there are holiday deadlines. From late September on we get calls from people who want floors done before Thanksgiving, and the December calls are almost always someone who waited.
What that means practically:
- Want an April or May start? Call in February. Six to eight weeks out is comfortable.
- October start, call in August.
- Finished and walkable before Thanksgiving? Early November is the last comfortable start for a 1,000 square foot install at three to five days. Mid October if we’re refinishing, because of the dry time between coats.
- January, February, and July are our quiet months. If your schedule is flexible, ask about those.
I’ll say the part most flooring companies won’t: book us in January and you get a crew that isn’t rushing your job to get to the next one. That’s worth something.
What we do regardless of the month
Timing is a smaller lever than process. On every job, whatever the season:
We take moisture readings on the subfloor and on the wood before anything goes down, and we don’t start if the difference is out of tolerance. We acclimate the material inside your house, not in a truck or a garage, which we get into properly in our post on hardwood acclimation in the Triangle. And we want the HVAC running at normal living conditions for several days before delivery, not flipped on the morning we show up.
Skip those and the month stops mattering, because the floor will move regardless of how nice the weather was. Nearly every gapping and cupping call we get on somebody else’s work traces back to one of those, not to a calendar decision. More on the local version of this in how Raleigh’s humidity affects hardwood floors.
One more thing. If you’re on a slab, which covers most of Brier Creek and a lot of newer North Raleigh construction, engineered is the more stable material and the whole seasonal question gets easier. And if you’re still weighing wood against vinyl plank for a busy house, timing isn’t your deciding factor anyway. LVP vs hardwood in Raleigh covers that one honestly.
Frequently asked questions
Is winter a bad time to install hardwood in Raleigh?
Not for an occupied house with the heat running normally. Winter indoor air is the driest of the year, so boards go in near their annual moisture minimum and expand as summer humidity climbs. That’s fine if the wood acclimated properly and the subfloor readings were in range. In a very dry house we may suggest adding humidity to hold the indoor level in the 30 to 50 percent band.
Can you install hardwood in Raleigh in the summer?
Yes, and we do it constantly. Air conditioning does most of the work. The summer jobs that need extra care are the unconditioned ones, like a new build without commissioned HVAC or a renovation running with the windows open. On those we either wait or bring in temporary conditioning.
What is the best month to install hardwood floors in Raleigh, NC?
April, May, and October, if you have the choice. Indoor and outdoor conditions sit closest together in those windows, so the wood goes down near the middle of its annual movement range. They’re also our busiest months, so book six to eight weeks out.
How far ahead should I book a flooring company in Raleigh?
Six to eight weeks for spring and fall. Two to four is usually workable in January, February, and July. For a holiday deadline, count backwards from the date you need it walkable and add a few days of slack for a subfloor surprise.
Does the season change how long the job takes?
Refinishing, yes. Humid summer air slows the cure between coats and can add a day. New installation is less affected. A typical 1,000 square foot hardwood job runs three to five days year round, and prefinished material skips on site finishing altogether.
Will my new floor gap in the winter?
A little seasonal movement is normal in solid wood and usually closes back up by summer. Gaps that stay open, or boards that cup, almost always point to a moisture problem at install rather than the month it was done.
