Many households are upgrading for comfort and views, while others are renovating properties bought as family or holiday homes. 04 ### Families and downsizers We see both families extending to make more room and people downsizing into bungalows and apartments. Both often want more light and less maintenance, which aluminium handles well. ### What Portstewart homeowners ask us for Bi-folds for family extensionsFamilies extending at the back of the house often want bi-fold doors that open fully onto the garden.

Local challenges ## What Portstewart homes are up against ### Promenade properties Seafront terraces on the Promenade take the full force of the weather. Frames must be fitted and sealed correctly to cope. ### Wind-driven rain Rain on the north coast often comes in sideways. Weak seals and old frames let water track in around the edges. ### Apartment access Upper-floor apartments need careful planning for getting large glass panels in. We plan access at survey. ### Mixed building ages Older terraces sit alongside new builds. The right approach to fitting differs between them, and we check each property individually. Local guide ## Planning your project in Portstewart ### Choosing glazing for a Portstewart home Portstewart homes range from Promenade terraces to large detached houses on the roads above the town. Before your survey, think about how your household uses the back of the house and the garden. Families who spend summer evenings outside usually get the most from bi-folds; people who mainly want light and a view are often better served by sliders or larger windows. ### Apartments on the Promenade and beyond Many Portstewart apartments have balconies or terraces facing the sea. Replacing balcony doors in an apartment block needs planning for access and lifting large glass, and it may involve the building's management. We'll look at access during the survey and talk you through what's involved before you commit. ### Renovating a family or holiday home We see a lot of Portstewart properties bought as family or holiday homes and then renovated. Often the windows and doors are replaced as part of a wider refurbishment, alongside new kitchens and internal changes. In those projects, RK Steel internal screens and glazed aluminium internal doors are popular ways to open up layouts while keeping rooms separate. ### Near the Strand and the golf links Homes towards Portstewart Strand and the golf courses are some of the most exposed in the area, with wind coming straight off the sea. For these properties, correctly sealed, low-maintenance aluminium frames are the sensible long-term choice. ### What to expect on fitting day in Portstewart Our fitters protect your home, remove the old frames, then fix and seal the new windows or doors. Every opening part is tested before we hand over. On Promenade properties and homes facing the Strand, seals on the weather side get extra attention. We tidy up as we go and explain how to operate and care for your new frames before we leave, and the balance is due once the job is complete. ### Matching what you already have If part of your Portstewart home already has aluminium doors or windows, we can usually suggest new frames and colours that sit well alongside them, so a phased upgrade still looks like one job.
