Why County Down customers compare our window and door range
A choice of materials
uPVC, aluminium and composite options give you different ways to approach appearance, glazing, maintenance and everyday use.
Bespoke sizing
Windows and doors are measured for the individual opening before manufacture, helping achieve an accurate specification and cleaner finished installation.
One planned process
From the initial survey through to fitting, the project is organised around the property’s requirements and the selected products.
Choose windows and doors around the way you use your home
The right window or door should suit more than the outside appearance of a property. Opening style, available space, glazing, ventilation, privacy, maintenance and everyday use can all influence the final choice.
With Smyth Window Systems, County Down customers can compare a broad selection of products for replacement and new-build projects. This includes uPVC windows, aluminium windows, sliding patio doors, bifold doors, French doors, composite doors and uPVC and aluminium entrance doors. The aim is to make the specification clear before fitting, rather than leaving important decisions until the installation stage.


Accurate measurements help create a cleaner finish
The condition and dimensions of an opening can affect which product and configuration are suitable. That is why the survey is an important part of the process rather than simply an administrative step.
Smyth Window Systems checks the opening, measurements, access and relevant product details before manufacture. Glazing, hardware, threshold, finish and configuration can then be confirmed as part of the specification. This creates a clearer route from initial enquiry through to installation.
Frequently asked questions
What window styles are available?

Can you supply and install doors as well?
Yes. We supply and install a range of doors, including uPVC sliding patio doors, bifold doors, French doors, composite doors and aluminium doors.
Is a survey required before ordering?
A survey allows the opening to be measured and assessed properly before the product is manufactured. It also provides an opportunity to confirm glazing, configuration, finish and hardware requirements.
