Local challenges ## What Belfast homes are up against ### Period terraces Older red-brick homes can have uneven openings and bay windows that need careful surveying. ### Tight city access Narrow streets, parking and rear access can make delivering large glass tricky. We plan it at survey. ### Damp and condensation Older homes with cold, failing frames often suffer condensation and mould around windows. ### Mixed building ages Belfast's mix of old and new housing means every survey is different. Local guide ## Planning your project in Belfast ### Victorian and Edwardian terraces Belfast's red-brick terraces and villas have real character. Replacing windows in these homes means getting proportions, bay windows and frame profiles right. Slim aluminium frames can modernise them without losing their look. We survey carefully because older openings are rarely perfectly square. ### Rear extensions Rear kitchen extensions are one of the most common Belfast projects. A large slider or bi-fold across the back, often combined with roof glazing installed by your builder, transforms a dark kitchen. On terraces, rear access can be tight, so we plan delivery and lifting during the survey. ### Steel screens in city renovations RK Steel internal doors and screens suit Belfast renovations, from period terraces to modern apartments. They divide open-plan spaces while keeping the light, and their slim, gridded profile adds character to any room. ### Parking and access City streets can make deliveries tricky. We'll agree parking, delivery times and access routes with you so the job runs smoothly and your neighbours are disturbed as little as possible. ### What to expect on fitting day in Belfast Our fitters arrive with your products, protect floors and furniture, remove old frames and fit, pack and seal the new windows or doors. Every opening part is tested before handover. We clear up as we go and walk you through how everything works, with the balance due on completion. ### Choosing between steel and aluminium in Belfast For period homes and city renovations, the choice between RK Steel and aluminium often comes down to the look you want and the size of the opening. Steel gives the slimmest classic profile; aluminium handles very large panels well. We'll help you weigh it up at survey. ### Apartments and townhouses Belfast's newer apartments and townhouses often have balconies and terraces with tired sliding doors. Replacing them can involve building management and careful lifting of large glass. We'll explain what's involved at survey, including access and timing, before you commit to anything. ### Free quote, no pressure Every Belfast job starts with a free written quote from your plans.
