Northern Windows & Joinery – Timber Windows, Doors & Bespoke Joinery

Northern Windows & Joinery is a long-established family-run business specialising in high-quality windows, doors, staircases and bespoke joinery throughout Belfast and Northern Ireland. With more than 40 years' experience, the company combines traditional woodworking skills with modern CNC manufacturing to produce products that suit both period properties and contemporary homes.

Whether you are replacing original sash windows, upgrading doors, fitting new timber windows or commissioning a bespoke staircase, Northern Windows & Joinery offers a personalised service from initial survey through manufacture and installation.

Timber Sliding Sash Windows

Northern Windows & Joinery specialises in timber sliding sash windows for traditional, Victorian and period-style properties. The company can provide sympathetic partial or full replacement of existing sash windows, helping retain the original character and proportions of a property while improving performance, comfort and energy efficiency.

Sliding sash windows are one of the company's flagship products, with experience in specialist and heritage-style projects where appearance, proportion and quality of workmanship are particularly important.

Timber & Wooden Windows

The company manufactures and installs timber and wooden windows using quality timber from sustainable sources. Options include traditional casement windows and bespoke designs produced to suit the style and requirements of the property.

High-performance energy-efficient double glazing is fitted as standard, helping combine the visual appeal of timber with the comfort and performance expected from a modern window system.

Timber, Composite & Entrance Doors

Northern Windows & Joinery supplies and fits a wide choice of timber, composite and entrance doors. Options include traditional wooden doors, composite front doors, PVC doors, patio and French doors and bespoke door sets.

For customers looking to open up living areas to gardens and outdoor spaces, aluminium bi-fold doors are also available, providing a modern alternative for extensions, kitchens and open-plan living areas.

Bespoke Timber Staircases

As an experienced timber staircase manufacturer, Northern Windows & Joinery produces both standard and bespoke made-to-measure staircases. Each staircase can be designed around the property and the customer's individual requirements rather than relying on a one-size-fits-all solution.

A wide choice of hardwood and softwood is available, including oak, pine, ash, beech, sapele, walnut and hemlock, with options for open or closed risers, different string styles, newel posts, balustrades and glass detailing.

Bespoke Joinery & Specialist Glazing

The workshop also produces a range of bespoke joinery products combining traditional craftsmanship with modern manufacturing technology. Specialist glazing services include high-performance double glazing and the refurbishment of existing lead lights, helping customers preserve original decorative features where possible.

uPVC Windows, Doors & Conservatories

Alongside its specialist timber work, Northern Windows & Joinery also supplies and fits uPVC windows, doors and conservatories in a range of styles and colours. This allows customers to choose between timber and low-maintenance PVC solutions depending on the property, budget and preferred finish.
