Because they slide rather than swing or fold, they take no room inside or out, and the big panes give you the clearest possible view when closed. We supply and fit bespoke aluminium sliders, including Origin. ### Who they suit Sliders suit homes with a view to make the most of, rooms where swinging doors would get in the way of furniture, and households who want a wall of glass but don't need to open the full width. They're common in coastal homes around Portrush, Portstewart and Castlerock. ### When to choose sliders Choose sliding doors if your priority is light and view. If you want the entire wall opening for summer parties, bi-folds may suit better. We fit both and we'll give you a straight recommendation. ### Why professional fitting matters Large sliding panels are heavy. The track has to be perfectly level and supported along its length, or panels become stiff and seals wear. Our fitters set the frame so the panels move with a light push and seal properly when closed.

Origin manufacturer example ### OS44 · 44mm A choice of sightline widths with strong, secure frames and large panel sizes. Origin manufacturer example ### OS77 · 77mm Origin sliding doors with a 77mm sightline, shown in Anthracite Grey. Origin manufacturer example - ### Configurations Two, three or more panels, sliding left, right or both ways, with fixed panels where needed.

The cost of waiting ## What happens if you leave it Old sliding patio doors are often the coldest, stiffest part of the house. ### Stiff, noisy runners Worn rollers and dirty tracks make old sliders hard to open, and they eventually stop being used. ### Cold glass and condensation Older units lose heat and attract condensation, which can damage floors at the threshold. ### Weak locking Worn locks on older sliders can leave the door less secure than it should be. ### Common mistakes we see - Choosing too many panels and losing the big-glass look. - Ignoring which side slides, so the opening ends up behind the sofa. - Underestimating panel weight when planning the opening and lintel. - Buying supply-only and finding nobody to take responsibility if it doesn't run right. Our process ## Five clear steps, start to finish - 01 ### Free written quote Send us your plans or drawings and we give you a written quote setting out the product, the brand, the finish and the fitting. No pressure to decide on the spot. - 02 ### Free survey once you go ahead When you accept your quote, we visit to take exact measurements and confirm every detail, at no cost. - 03 ### Order with a 65% deposit Once you're happy, a 65% deposit places the order with the manufacturer. Your products are made to the exact measurements taken at survey. - 04 ### Installation by our fitting team Our fitters remove the old frame, prepare the opening, install the new sliding doors, seal it and check it opens, closes and locks smoothly. - 05 ### Completion and handover We tidy up, walk you through operation and care, and confirm the manufacturer's guarantee. The balance is due on the day of completion, and aftercare call-outs on doors we've fitted are free. Benefits ## What you get ### Maximum glass Fewer, larger panels mean slimmer sightlines and a clearer view. ### Saves space Nothing swings into the room, so furniture can sit closer to the doors. ### Smooth operation Correctly fitted panels glide with a light push. ### Guarantee on Origin Choose Origin and the doors carry a 20-year manufacturer's guarantee. ### Weather-tough Aluminium doesn't rot or warp in coastal weather. ### Free aftercare Aftercare call-outs on sliders we've fitted are free. In detail ## Options, materials and methods Everything worth knowing before your survey, so you can make a confident decision. ### Made in England, so turnaround is quick Origin designs and manufactures its products in-house in England. Because they are made in the UK rather than shipped from abroad, we can offer quick turnaround times from order to fitting. We'll give you a realistic date with your quote. ### Truly bespoke No two openings are the same. Every Origin product is made to the exact measurements taken at your survey, in your choice of colour, glazing, handles and configuration, so it fits the opening rather than the opening being forced to fit the product. ### Two, three and four-panel layouts A two-panel slider has one fixed and one moving panel. Three and four-panel layouts let you open a wider gap or open from the middle. The best layout depends on your opening width and where you want to walk through. ### Sliders versus bi-folds Sliders give more glass and fewer frame lines; bi-folds give a wider opening. In rooms where the doors are mostly closed, sliders usually win. Where you entertain outdoors often, bi-folds may be worth it. ### Thresholds and tracks Tracks and thresholds must drain water away while keeping the step into the garden comfortable. We'll explain the options for your floor and patio levels. ### Finishes Powder-coated frames come in a wide range of colours, and you can match sliders to aluminium windows elsewhere in the house. ### Making the most of a view If your room looks out over a garden, the countryside or the coast, the frames are what get in the way. Sliding doors use fewer, larger panels than most other door types, so there are fewer vertical lines across the view. In homes around Portrush, Portstewart and Castlerock in particular, customers often choose sliders for exactly this reason. ### Daily use and safety Sliding doors are easy to use every day: a light push opens a gap for the dog, the children or fresh air, and the door doesn't swing into the room or catch the wind outside. At handover we show you how the locking works and how to keep the track clean so the panels keep running smoothly for years. ### Before your survey To get the most from your survey, have a think about a few things beforehand: how you use the room day to day, the look you're aiming for, any colours or finishes you already like, and whether other building or decorating work is planned. Photos of styles you like are useful too. None of this is essential, as we'll guide you through every choice, but it helps us give you a precise origin sliding doors quote in a single visit. ### Paying for your project We keep payment simple and transparent. A 65% deposit is taken to order your products from the manufacturer, and the balance is due on the day of completion, once the job is finished. We don't publish prices, because every home is different. Get in touch for a quote. Your written quote will show exactly what you're paying for. ### Choosing a brand We supply and fit products from manufacturers rather than making our own, which means we can recommend what genuinely suits your home. Origin aluminium is our best seller and carries a 20-year manufacturer's guarantee. RK Steel is our steel brand for internal doors, with a fire-rated option. For front doors we supply Bel'M and Palladio. At survey we'll explain the differences in plain terms. ### Understanding the guarantee Because we don't manufacture, the guarantee on your product is the manufacturer's guarantee, and it varies by brand. Origin products carry a 20-year manufacturer's guarantee. For other brands, we'll confirm the guarantee for your specific product in writing with your quote, so there are no surprises later. ### Getting an accurate quote Every opening is different, so we don't publish prices. The fastest route to a firm figure is a free quote from your plans, followed by a free survey once you go ahead: we measure, check the condition of the opening and talk through the finish, glazing and hardware you want. You'll get a written quote listing exactly what's included before you decide anything. ### Homes we work on Our customers are mainly households: replacements in existing homes, renovations, extensions and self-builds. P Black and Son supplies products from manufacturers and fits them, so you deal with one team from first visit to final handover.
