Side Hinged Garage Doors: Installation & Replacement FAQs

If you’re considering a new side hinged garage door, or replacing an existing one, you probably have questions about cost, materials, sizing and how the installation process works. Below we’ve answered the questions we’re asked most often, so you can make an informed decision before getting a quote.

Frequently Asked Questions

What is a side hinged garage door?

A side hinged garage door is a garage door made up of two leaves (or occasionally one) that open outward on hinges, in the same way a standard external door does, rather than lifting upward or rolling. They’re often called “garage doors that open like French doors” and are one of the oldest and simplest garage door styles still in use today.

What’s the difference between a side hinged garage door and an up-and-over door?

An up-and-over door swings or slides upward on a single panel, taking up ceiling space inside the garage as it opens. A side hinged door opens outward on two independent leaves, leaving the full ceiling height and width of the garage clear. This makes side hinged doors better suited to garages used for storage, workshops, or where roof-mounted storage racks are in place.

What materials are side hinged garage doors available in?

Side hinged garage doors are commonly available in timber, GRP (glass reinforced plastic), steel, and composite/insulated panel construction. Timber gives a traditional look and can be painted or stained to match a property, GRP offers a low-maintenance timber-effect finish, and steel or insulated composite doors are typically chosen for security and thermal performance.

Are side hinged garage doors more secure than other types?

Side hinged doors can be built to a high security specification, particularly when specified with multi-point locking, shootbolts top and bottom, and a solid timber or steel core. Security depends more on the specification — locking mechanism, hinge type, and panel construction — than on the door style itself, so it’s worth discussing security requirements at the quote stage.

Can side hinged garage doors be insulated?

Yes. Insulated side hinged garage doors are available in both timber and composite/steel construction, typically using a foam core panel to improve thermal performance. This is a popular choice for garages that are used as workshops, gyms, or additional living space, or for anyone looking to reduce heat loss from an integral garage.

How much does a side hinged garage door cost?

Costs vary depending on size, material, insulation, and locking specification, with timber and bespoke doors generally costing more than standard steel options. Because pricing depends heavily on the individual opening and specification, the most accurate way to get a cost is via a made-to-measure quote rather than a generic price list.

Can side hinged garage doors be made to a bespoke size?

Yes, side hinged garage doors are typically made to measure, which makes them well suited to older properties, non-standard openings, or garages that don’t match modern standard door sizes. Bespoke manufacture also allows for custom features such as a wicket (pedestrian) door built into one leaf.

What is a wicket door and can I have one fitted?

A wicket door is a small pedestrian door built into one leaf of a side hinged garage door, allowing you to walk in and out of the garage without opening the full door. This is a common addition for garages used regularly for storage or as a workshop, and can usually be specified at the manufacturing stage.

Do I need planning permission to install a side hinged garage door?

In most cases, replacing an existing garage door with a side hinged version does not require planning permission, as it falls under permitted development rights. However, this can vary depending on whether the property is listed, in a conservation area, or if the garage forms part of a new build or extension, so it’s worth checking with your local planning authority if you’re unsure.

How long does it take to install a side hinged garage door?

A straightforward replacement, where the existing frame and opening are reused, can typically be completed within a day. Installations involving a new frame, structural alterations to the opening, or bespoke doors may take longer, and lead times for manufacture should also be factored in before fitting can take place.

Can I replace an up-and-over door with a side hinged door?

Yes, this is a common upgrade. In many cases the existing opening can be reused with a new frame fitted to suit the side hinged mechanism, though the opening may need adjustment depending on its condition and dimensions. A survey of the existing opening is the best way to confirm what’s involved.

How do side hinged garage doors lock?

Most side hinged garage doors use a shootbolt locking system, with bolts engaging top and bottom of one or both leaves, often combined with a euro cylinder or mortice lock for day-to-day access. Higher specification doors may include multi-point locking for additional security.

How much maintenance do side hinged garage doors need?

Maintenance depends on material: timber doors generally need periodic repainting or re-staining and a check of hinges and locks, while GRP, steel, and composite doors typically only need occasional cleaning and a lubrication check on hinges and locking mechanisms. Regular checks help keep the door operating smoothly and extend its lifespan.

Will a side hinged garage door fit my existing opening?

In most cases, yes — side hinged doors are made to measure and can be fitted to match an existing opening, including older or non-standard sizes. Where the opening is out of square or in poor condition, some remedial work to the frame or brickwork may be recommended before fitting to ensure a proper fit.

Should I install a side hinged garage door myself or use a professional installer?

While a competent DIYer can fit some side hinged doors, professional installation is generally recommended, particularly for insulated, bespoke, or heavier timber doors, to ensure the door is correctly aligned, weathertight, and operates smoothly. Professional installation also typically comes with a workmanship guarantee alongside the manufacturer’s product warranty.
