Double Glazing & uPVC Repairs in Sprowston

Homeowners in Sprowston often assume that faulty windows or doors need replacing entirely. In reality, most problems are caused by worn components rather than the frames themselves. Professional repair is usually the most cost-effective and practical solution.

We provide specialist double glazing and uPVC repairs throughout Sprowston, helping restore security, insulation and smooth operation without the expense of full replacement.


Sealed Unit Replacement (Misted Glass)

One of the most common issues we see is misted or cloudy double glazing. This happens when the sealed unit fails and condensation forms between the panes. The window frame is normally still perfectly sound. By replacing just the glass unit, we restore clarity and thermal performance while keeping disruption to a minimum.

Broken Window Hinges & Handles

Window hinges and handles also wear over time. If a window feels stiff, doesn’t close tightly, or drops slightly when opened, worn hinges are often the cause. Replacing them restores proper alignment and prevents draughts. Handles that spin or feel loose can also be replaced quickly and affordably.

Door Locks, Hinges & Adjustments

Security is another major concern. Faulty locking mechanisms or worn cylinders can leave doors vulnerable. We repair and replace multi-point locking systems, door barrels and window locks to ensure your property remains secure.

uPVC doors frequently develop alignment issues. If your door catches on the frame, needs lifting to lock, or won’t latch correctly, adjustment or hinge replacement usually resolves the issue. In many cases, a simple mechanical repair brings the door back to full working order.
