There’s something special about moving into a home no one else has lived in. But while everything’s brand new, the first year can bring a few surprises as the house settles and dries out. Here’s what to expect—and what to keep an eye on.
Settling is completely normal
You might notice small cracks around doors or windows, or little bumps on the walls. Don’t worry—this is all part of the house adjusting. New buildings shift slightly as they settle onto their foundations. At the same time, materials like plaster, wood and concrete are drying out, especially after being exposed to the elements during construction.
This process usually takes 9 to 12 months. You may see “shrinkage” cracks, usually no more than hairline in width. If you spot anything wider than 5mm, it’s worth checking with your builder.
White marks and condensation
One thing many new homeowners notice is white, powdery marks on walls or brickwork. This is called efflorescence—it’s just natural salts coming to the surface as the building dries. It can be wiped off and tends to fade over time.
Condensation is also more common in new homes. Because moisture is still being released from the structure, it’s important to keep the house well ventilated. Use extractor fans, open windows regularly, or keep trickle vents open—especially in winter.
A few things you can do to help
There are some simple ways to keep things running smoothly in your new home:
- Keep your heating at a steady, comfortable temperature
- Avoid blasting the heat, as sudden changes can make shrinkage worse
- Ventilate regularly to reduce condensation
- Hold off on painting or wallpapering until the house is fully dry
Builder paint is breathable, allowing moisture to escape. Painting over it too soon can trap that moisture and cause problems down the line. If you want to personalise the space, focus on soft furnishings, lighting, and artwork for now.
Don’t forget the garden
Most new builds come with basic landscaping, but lawns can take time to bed in. If you’re laying turf, aim to do it quickly so the soil stays in place. Avoid walking on it too much for the first six to eight weeks so it has time to settle.
Make a snagging list
It’s a good idea to walk through your home and list anything that doesn’t look or feel quite right. Most new builds are covered by a two-year warranty, so now’s the time to flag issues like sticking doors, loose tiles, or faulty fixtures.
Buying a new build is exciting—and with a bit of care in the first year, you’ll be setting yourself up for a solid start in your new home.
