Our services in windows and doors
We install and replace windows and doors fully tailored to your building and project. Thanks to our experience in building maintenance we often combine these works with other modifications such as painting, finishing and technical installations.
Installation and replacement of windows
At DCO Construction Company we provide the placement and replacement of windows in any size, style and material. Whether you choose aluminium windows with a sleek, modern look, PVC windows with excellent thermal insulation or wooden windows for a warm, classic look - we ensure a perfect fit. We take charge of the entire process: measuring, delivery, expert installation and precise finishing.
When replacing existing windows, we ensure efficient dismantling of the old frames and glass panes without damage to surrounding walls. If necessary, we repair facade finishing, painting or interior finishing immediately after installation. We are also the right place for large glass panes, fixed window panels, tilt-and-turn windows and sliding windows. So we combine aesthetics, sustainability and energy efficiency in one project, fully tailored to your building.
Installation and repair of doors
We install and repair all types of doors, from robust entrance doors for companies up to fire doors and automatic sliding doors for public areas. Each door is perfectly adjusted for smooth use and optimum safety. Think of interior doors, exterior doors, industrial sectional doors and access doors with integrated security hardware.
For repairs, we tackle problems such as poorly closing hinges, faulty locks or damaged door panels quickly and professionally. If a doorway needs to be modified - for example, widened for larger access - we also carry out the masonry works, dismantling and finishing yourself. This gives you a single point of contact that manages the entire process, from demolition to assembly and delivery.
Functional and technical finishing
When installing new windows and doors we look beyond just assembling the product. We also take care of all the associated finishing and technical integration. That means we finish surrounding walls with gyproc, plastering or painting, adjusting floors if necessary, and repairing facades for a perfect seamless result.
We also integrate additional functionalities such as automatic door control, access control, shutters, awning and safety devices. Also for installing natural stone sills, insulating connections and watertight finishing of external joinery. That way, your windows and doors will not only be visually perfect, but technically match the rest of your building.
