Building Over Winter: What Can Go Ahead in Cold Weather and What Should Wait

Many projects run through the colder months. With sensible planning, a lot of work can go ahead, but some activities are sensitive to low temperatures, rain and short daylight hours.

What is affected by cold weather

• Concrete and mortar: low temperatures slow curing and frost can damage fresh work, so protection or timing changes may be needed

• Rendering and external plastering: they need suitable conditions to cure and dry

• External painting and sealants: damp surfaces and low temperatures affect adhesion

• Roofing: high winds and wet conditions can make roof work unsafe or impractical

What can usually continue

• Internal work once the building is weathertight, such as first fix, plastering and carpentry

• Structural steelwork and timber frames, subject to weather and safety conditions

• Interior finishes, kitchens and bathrooms

• Design, approvals and ordering for later stages

Plan the sequence

The key is to get the building weathertight as early as possible, so internal trades can carry on regardless of conditions outside. Where groundworks and roofing fall in winter, programmes should allow extra time for weather days.

Drying and heating

Plaster, screed and paint need time to dry, and cold, damp conditions slow this. Temporary heating and ventilation can help, but should be planned carefully.

Shorter days

Less daylight affects external work and site safety. Good lighting, tidy sites and early starts help keep things moving.
