5 Common Plasterer Problems and When to Call a Professional

The problems that come up most

These are the jobs plasterers are most commonly booked for. Catching them early almost always costs less:

• blown plaster that sounds hollow when tapped
• cracks along ceiling joints
• crumbling plaster around windows
• artex ceilings that need covering
• damp-damaged plaster after a leak

What you can safely check yourself

Before calling anyone, gather information: when the problem started, whether it's getting worse, and clear photos. This helps a professional give you a realistic first assessment and helps you describe the job accurately when collecting quotes.

Basic observation is always safe; DIY repair is not always. If the problem involves gas, electrics, working at height or the structure of your home, stop at observation and call a professional.

Signs it's time to book someone

Book a professional when the problem is getting worse, when it involves safety, when your own attempts haven't held, or when you simply don't know the cause. A correct diagnosis is usually cheaper than a wrong repair.

For context on cost: Plasterers typically charge £150–£250 per day. Skimming a standard room usually costs £300–£500 including materials.

Choosing who to call

There is no registration scheme for plastering, so evidence matters: ask to see photos of recent finished work and check reviews for comments on finish quality and mess control.

Check recent reviews before booking — Hammerscore company pages for plasterers combine ratings from several platforms, and the low-star reviews tell you most about how problems were handled.
