What we do

  • Window Repairs

    Need window repairs in Bristol? The UPVC Doctor Southwest fixes every kind of UPVC and aluminium window problem across Bristol and the surrounding areas — broken handles, faulty locks, failed seals, blown double glazing, stiff mechanisms and cracked glass.

    Most repairs are completed in a single visit, with no call-out charge, no deposit and a fixed price agreed before we start.

  • Door Repairs

    The UPVC Doctor Southwest repairs UPVC and composite doors across Bristol and the surrounding areas. If your front door will not lock, your back door has dropped, your patio door sticks or a handle has broken, we can fix it — usually in one visit.

  • Glass Unit Repairs

    The UPVC Doctor Southwest replaces glass units and sealed units across Bristol and Bath. Cracked pane, smashed window or a failed sealed unit? We remove the damaged glass and fit a new unit into your existing frames — no need to replace the whole window.

  • Double Glazing Repairs

    The UPVC Doctor Southwest carries out double glazing repairs across Bristol. Whether the problem is the hardware, the sealed glass unit or the frame seals, we diagnose and fix it — most repairs the same day, with no call-out charge.

  • Misted Double Glazing

    If you can see mist, fog or a cloudy haze between the panes of your double glazing, the sealed unit has failed. It is one of the most common double glazing problems and one of the easiest to fix. The UPVC Doctor Southwest replaces blown sealed units across Bristol and Bath: the glass is replaced, your frames stay, and the window looks and performs like new.

  • Patio Door Repairs

    Searching for patio door repairs near you? The UPVC Doctor Southwest repairs all types of patio doors across Bristol and Bath — sliding, inline, bifold and French. If your door is stiff, stuck, jumping the track, leaking or will not lock, we fix it.

  • Door Lock Repairs

    A door that will not lock is not something to leave until next week. The UPVC Doctor Southwest repairs UPVC door locks across Bristol — multipoint failures, broken euro cylinders, stiff mechanisms and locks that only half-engage.

    We carry the most common lock brands on the van, so most repairs are done in a single visit.

  • Window Handle Replacement

    Got a stiff, loose, broken or seized window handle? The UPVC Doctor Southwest replaces UPVC window handles across Bristol — all makes and models, with genuine like-for-like parts, usually in a single visit.

  • Window Lock Repair

    A window that will not lock is a security risk, and it is almost always repairable. The UPVC Doctor Southwest repairs UPVC window locks across Bristol — failed gearboxes, worn locking points and seized mechanisms — usually in a single visit.

  • Window Seal Replacement

    Feeling a draught through a closed window, or seeing water or condensation around the frame? The rubber seals have usually perished. The UPVC Doctor Southwest replaces UPVC window seals and gaskets across Bristol to stop draughts, leaks and damp.

  • Door Mechanism Repair

    If your UPVC door has gone stiff to lock, or the handle lifts but nothing engages, the multipoint mechanism (the gearbox) has usually failed. The UPVC Doctor Southwest replaces UPVC door mechanisms across Bristol, often in a single visit.

  • Conservatory Repairs

    The UPVC Doctor Southwest repairs conservatories across Bristol and Bath — the doors, windows, sealed units, seals and roof components. If your conservatory is leaking, draughty, misting up or the doors will not lock, we can put it right.
