What is the Best Time of Year for Door Installation?

Choosing the right time of year to install a new door isn’t just about convenience—it can also affect how well your door performs in the long term. Timber doors, in particular, are sensitive to changes in temperature and humidity, which means the season you choose for installation can make a real difference.

So, what is the best time of year for door installation? Let’s explore how the seasons affect timber doors and why timing matters.

How Weather Affects Timber Doors

Timber is a natural material that expands and contracts depending on environmental conditions. Heat and humidity can cause wood to swell, making doors stick or warp. Cold, dry conditions can cause wood to contract, leaving small gaps that let in draughts. Rapid shifts between hot and cold can put stress on the door and frame. That’s why choosing the right season for installation is key to ensuring a snug fit and long-lasting performance.

Spring: A Popular Choice

Spring is often considered one of the best times for door installation. Temperatures are mild, which reduces the risk of timber swelling or contracting during fitting. Lower humidity compared to summer means the door settles more evenly. It’s an ideal time to prepare your home for the warmer months ahead.

Best for: A balance of stable conditions and comfortable installation weather.

Summer: Proceed with Care

Summer may seem convenient, but high temperatures and humidity can sometimes pose challenges. Timber is more prone to swelling in humid conditions, which may affect how it fits in the frame. If installed during a hot spell, the door might feel slightly looser once cooler weather arrives. On the other hand, warm weather makes for quicker drying of sealants and finishes.

Best for: Exterior doors, as sealants cure faster in warm weather.

Autumn: A Practical Option

Autumn can also be a good time to install timber doors, particularly early in the season. Cooler, stable weather helps timber settle into place, and it’s the perfect time to prepare your home for winter insulation. However, late autumn may bring damp conditions, so weatherproofing is essential.

Best for: Getting doors fitted before the coldest months set in.

Winter: Less Ideal, but Still Possible

While winter isn’t usually the first choice, it’s still possible to install doors during colder months—especially if urgency demands it. Timber contracts in dry, cold air, which may lead to gaps forming when temperatures rise again. Installation can also be more disruptive with shorter days and harsher weather. Extra care must be taken to ensure proper sealing against draughts.

Best for: Emergency replacements rather than planned upgrades.

FAQs About Timber Door Installation

Can you install a timber door in winter?
Yes, but it requires extra care. Timber contracts in cold, dry conditions, which can create small gaps once the weather warms. Professional installation and thorough sealing will help reduce these risks.

Do timber doors expand in summer?
They can. Timber is a natural material and will swell slightly in hot, humid weather. Choosing high-quality timber doors and ensuring correct installation helps manage this natural movement.

What happens if I install my door in very humid weather?
If a door is fitted during high humidity, it may feel tighter once the air becomes drier. This is why mild, stable conditions like spring or early autumn are usually preferred.

Is there a “bad” time to install a door?
Not necessarily. With professional installation, timber doors can be fitted year-round. However, spring and autumn offer the most stable conditions for long-lasting results.
