Professional Silicone & Caulking for Windows and Doors in Leicestershire
Failed silicone sealant is one of the most overlooked causes of draughty, damp, and energy-inefficient homes across Leicestershire. Over time, the flexible silicone bead that seals your window and door frames to the surrounding masonry or plasterwork shrinks, cracks, peels, and turns black with mould. Window Repair Man specialises in professional silicone removal and re-sealing for both windows and doors, restoring your home's weatherproofing, thermal performance, and appearance in a single visit.
01.Why Window & Door Silicone Fails
Silicone sealant has a finite lifespan. Even the best-quality neutral-cure silicone will begin to degrade after 10 to 15 years of exposure to Leicestershire's freeze-thaw cycles, UV sunlight, and rain. As the silicone ages, it loses elasticity and can no longer flex with the natural movement of the frame. The result is cracks, gaps, and peeling sections that allow rainwater to track behind the frame, cold air to penetrate in winter, and humid air to become trapped within the cavity. Mould quickly establishes itself on degraded silicone, not only looking unsightly but also creating a health hazard for occupants, particularly those with respiratory conditions.
02.Window Frame Silicone Sealing & Weatherproofing
The junction between a uPVC, aluminium, or timber window frame and the surrounding brickwork or render is sealed with a bead of silicone. When this seal fails, rainwater can permeate the gap and cause serious structural damage, including saturated insulation, blown render, and internal damp patches around the window reveal. Our engineers remove all traces of the old, failed silicone using specialist cutting tools and chemical preparation agents, thoroughly clean and prime the substrate, and apply a fresh, high-quality, colour-matched silicone bead with a perfectly tooled finish. The result is a flush, professional seal that is fully weatherproof, UV-resistant, and guaranteed to last.
03.Door Frame & Threshold Caulking
External door frames face the same weatherproofing challenges as windows, but often with greater levels of movement due to the weight and daily use of the door. The silicone or flexible mastic caulk at the junction between the door frame and the masonry can split or gap, allowing cold draughts to whistle in around the frame even when the door itself seals correctly. We apply flexible, paintable mastic caulk to door frames and repoint the threshold sealant where required, eliminating cold spots and preventing water ingress at the base of the frame. We also seal the internal reveals around both windows and doors to prevent condensation from forming at the cold junction.
04.Mould Removal, Hygiene Caulking & Internal Resealing
Bathrooms, kitchens, and other high-humidity rooms often suffer from mouldy silicone around internal window frames. Standard bathroom sealant is formulated with anti-mould additives, but over time the mould can penetrate the sealant itself, making surface cleaning ineffective. We fully remove all contaminated silicone, treat the substrate with a mould-killing preparation, and apply a fresh anti-fungal silicone or caulk in the appropriate colour. We also reseal the internal junction between window boards and plasterwork where gaps have appeared, preventing draughts and the ingress of insects. This comprehensive internal resealing service is popular with homeowners, landlords, and property managers across Leicestershire who want a professional, lasting finish.
