UPVC (unplasticised polyvinyl chloride) is the most common material for window frames, door frames and conservatories in the UK. It’s durable, low-maintenance and weather-resistant — but it does scratch, crack, discolour and suffer impact damage over time. Professional UPVC repair can restore damaged frames and panels at a fraction of the cost of replacement. Here’s what you need to know.
Common Types of UPVC Damage
Scratches
UPVC scratches fairly easily from keys, tools, abrasive cleaning products, or objects rubbing against the frame. Light scratches can be polished out or repaired with colour-matched compounds. Deep scratches that penetrate the surface require filling and re-colouring.
Cracks and Chips
UPVC can crack under impact or as it ages and becomes more brittle. Cracks in UPVC window and door frames can be repaired with specialist compounds and re-finished to blend with the surrounding material. Structural cracks that affect the security or weatherproofing of the frame need evaluation by a window specialist.
Yellowing and Discolouration
White UPVC frames yellow over time as a result of UV exposure and oxidation. This is particularly noticeable on south-facing elevations. UPVC discolouration can be addressed by professional re-colouring or spray painting using flexible, UV-resistant coatings formulated for UPVC substrates.
Impact Damage
A hard knock — a ladder leaning against the frame, a door slammed against a wall, a BBQ pushed into a conservatory panel — can leave dents, splits or holes. Many forms of impact damage can be repaired rather than requiring frame or panel replacement.
UPVC Repair vs UPVC Spray Painting
UPVC repair addresses specific areas of damage — chips, scratches, cracks. UPVC spray painting (also offered by Shazam Repairs) addresses the overall appearance — changing or refreshing the colour of frames that have discoloured or that the owner wants to change. Many jobs involve both: repairing damage first and then spray painting the frames to a new colour for a complete refresh.
