Professional Silicone & Caulking for Windows and Doors in Nottinghamshire
Cracked, mouldy, or missing silicone sealant around your windows and doors is a common but frequently overlooked cause of draughts, damp, and rising energy bills across Nottinghamshire homes. Window Repair Man specialises in the professional removal of failed sealant and the application of fresh, high-quality silicone and mastic caulk to all types of window and door frames — from uPVC casements to timber cottage windows and composite front doors. We restore your property's weatherproof seal in a single visit, eliminating draughts and protecting against damp damage.
01.Why Silicone Sealant Fails
Even premium exterior silicone has a finite lifespan. Typically lasting 10 to 15 years, it is subject to constant exposure to Nottinghamshire's seasonal temperature extremes, driving rain, UV sunlight, and the thermal movement of the window or door frame against the surrounding masonry. As it ages, silicone loses flexibility, hardens, and begins to crack or peel. Once a gap opens, rainwater tracks directly behind the frame. In winter, this water freezes and expands, widening the gap and accelerating damage to surrounding plasterwork, insulation, and internal finishes. Black mould follows rapidly in the resulting damp conditions.
02.External Window Silicone Resealing
Our external silicone resealing service addresses the full perimeter of each window frame where it meets the surrounding masonry, render, or cladding. We use professional-grade, low-modulus silicone sealants that remain permanently flexible, accommodating thermal movement without cracking. Before applying fresh sealant, we completely remove all traces of the failed bead, thoroughly clean and degrease the substrate, and prime where necessary for maximum adhesion. The fresh silicone is tooled to a clean, concave profile that encourages positive water runoff. We stock a wide range of colours to match common frame shades and masonry tones, ensuring a discreet, professional finish on properties across Nottinghamshire.
03.Door Frame & Threshold Sealing
External door frames are subject to even greater movement than windows due to the weight and repeated impact of daily door use. The silicone or mastic caulk at the junction between the door frame and masonry cracks and gaps, allowing cold draughts and rainwater to penetrate around the frame perimeter. We apply flexible, UV-stable mastic caulk to all door surrounds and reseal the threshold joint where required, eliminating draughts and preventing water ingress. We also address the vulnerable junctions at door head flashings and side reveals to provide comprehensive weatherproofing.
04.Mould Removal & Internal Resealing
In kitchens, bathrooms, and utility rooms, the internal silicone sealant around window sills and frames is prone to mould contamination that penetrates the body of the sealant and cannot be remedied by surface cleaning alone. We fully remove all contaminated sealant, treat the substrate with a mould-inhibiting preparation, and apply fresh anti-fungal silicone in the appropriate colour. We also reseal internal window board junctions to prevent cold air tracking through the reveal and causing additional condensation, providing a comprehensive internal resealing service that is popular with homeowners, landlords, and property managers throughout Nottinghamshire.
