What Belfast customers can consider before fitting
Styles for modern and traditional homes
Choose from a range of window and door styles to complement the property, from practical casements to contemporary aluminium and large glazed openings.
Specification based on your property
The final survey checks the opening dimensions and project requirements before manufacture, helping ensure the selected product is properly suited to the installation.
Supply and installation together
Smyth Window Systems can manage the process from product selection and measuring through to fitting, keeping the specification clear from the outset.
Find windows and doors that work for your Belfast property
Different properties call for different approaches. A replacement window may need to match the existing character of the building, while an extension or modern home might benefit from slimmer frames and larger areas of glazing.
Smyth Window Systems supplies and installs a range of windows and doors for Belfast customers, including uPVC windows, aluminium windows, sliding patio doors, bifold doors, French doors, composite doors and uPVC or aluminium entrance doors. We can work through the available configurations, glazing, finishes and hardware to help you select an option that suits the opening and the overall project.


The details behind a successful installation
A new window or door can only fit properly when the opening has been assessed correctly. Measurements, structural condition, access and the chosen configuration all need to be considered before manufacture.
Our survey process helps confirm those details before fitting begins. Through Smyth Window Systems, the installation is planned around the individual property, giving you a clear specification and helping the fitting stage proceed without unnecessary surprises.
