UPVC Window Specialist Repairs in Streatham

Full maintenance for double glazed units including hinge replacement, handle fixes, and espagnolette gearbox alignment for homeowners across the local area.

If you are struggling with a window that refuses to lock, a loose handle, or frames that let in a draught, our local team at Streatham Locksmiths is here to help. We specialise in expert component replacement and precise structural alignment to restore the security and warmth of your property. Our journey starts when you head to our Home page or Contact page to request assistance. A typical repair visit involves a full diagnostic check of your UPVC frames, followed by a clear overview of the required mechanical work. We focus on restoring the integrity of your fixtures efficiently, often preventing the need for an Emergency Locksmith or more invasive Burglary Repairs should a weak window be targeted. By choosing professional maintenance, you ensure your South London property remains energy efficient and secure.

Common UPVC Window Issues

Misaligned Sash

Frames that scrape when closing or do not sit flush due to worn hinges or sagging glass units.

Espag Failures

Problems where the inner locking strip fails, leaving the sash permanently shut or open.

Broken Hinge

Damaged friction stays that cause the window to pull away from the fixed frame.

Seized Handles

Internal parts that have snapped, meaning the handle spins without locking the unit.

Cold Draughts

Air gaps caused by compressed seals or hinges that no longer pull the sash tightly.

Faulty Restrictor

Safety mechanisms that have jammed or broken, preventing windows from opening safely.

Full Service Provisions

Our technicians inspect the complete UPVC window system before recommending work. We check the handle, locking strip, keeps, hinges, seals and the position of the sash within the frame. A window that will not lock may have a failed mechanism, but it can also be caused by dropped hinges or poor alignment placing too much strain on the locking points. Diagnosing these connected parts first helps avoid unnecessary replacements.

Many window faults can be repaired by replacing an individual handle, hinge, gearbox or espagnolette mechanism while retaining the existing frame and glass. Adjustment may be sufficient where the sash has dropped or no longer closes evenly. Replacement of the complete window is normally considered only when the frame is badly distorted, the sealed unit or structure has failed extensively, or suitable components are unavailable. We explain the condition and practical choices clearly before work continues.

After a repair, we test opening, closing and locking several times and check that the sash pulls evenly against the seals. Keeping channels clear, using handles gently and arranging attention when stiffness first develops can reduce strain on internal mechanisms. Do not force a handle that stops partway, because this can turn a minor alignment issue into a broken gearbox.

We serve Streatham, Streatham Hill, Streatham Common, Streatham Vale and surrounding South London areas. For connected door problems, see UPVC Door Repairs or Bifold Door Repairs. If the window has been damaged during a break-in, our Burglary Repairs page explains the next steps. Use the Contact page or Call Now button to arrange an assessment.

  • We offer more than just basic fixes; our services include Specialist Espagnolette Gearbox Repair, New Friction Stay Hinge Installation, and Replacement Security Window Handles. We also conduct Professional Frame Realignment and Draught Proofing to ensure your home stays quiet and warm. If you are refurbishing, you might also be interested in our Bifold Door Repairs or Lock Changes & Security Upgrades to complement your window maintenance. Regular care, such as clearing debris from tracks and lightly lubricating metal parts, can significantly extend the life of your UPVC units. Deciding between repair and replacement often comes down to the condition of the frame; if the plastic is intact, we can usually replace the internal hardware for a fraction of the cost of a new window installation.
