How Do I Make My Loft Hatch Bigger?

If you want to enlarge your loft hatch, it’s essential to know what’s involved in the process and ensure that you have all the tools and equipment necessary before beginning the job.

Plastic Loft Hatch - Twist Action

We will talk you through the process of widening your loft hatch without weakening the roof or supporting structures. We’ll also discuss the kinds of loft hatches you can install and cover the regulations that must be checked or put in place to ensure your project meets building regulations.

If you plan to convert your loft into living accommodation, you must get building regulation approval before starting the work. Different project types and home types will have additional rules, so always get in touch with your local council first so you can ensure that you are adhering to any regulations that are in place.

Loft Hatch Widening - Things To Consider

Most roofs have been built specifically to cope with their particular weight. Some roofs have trusses to support them, while others do not. However, before cutting through or removing any supporting structure, you must be sure you will not weaken your roof. If in any doubt, this may be a job left to a professional.

•Please note that Loft Centre do not provide services to alter loft hatches, we only supply the hatch.

Always make certain that the enlargement you require will not mean cutting through any main supporting beams or timber lintels that protrude into your loft.

Types of Loft Hatches - Which Will You Use?

Some people choose to build a bespoke hatch for their space. The majority, however, will buy a ready-made loft hatch. If you go with the latter, you need to ensure that the opening is measured so the hatch will fit correctly. Loft hatches are made to set sizes, so before widening your gap, you should consider this factor; otherwise, a custom solution may become your only option.

It may also be a requirement that your loft hatch needs to meet fire regulations. Where possible, look for a hatch with fire-resistant insulation material fixed to the back. This will ensure that warm air doesn’t escape from your home into the loft and that you and your loved one will be safer in the event of a fire.

Draught seals and locks are other factors to consider. Draught seals can prevent air from being lost in the roof, and a lockable loft hatch can be a good idea if you have concerns over children trying to access the area.

Measuring Your Hatch Opening

When you measure your new opening, make sure you leave space for adding two timbers on either side. These timbers need to be the same size as your current joists, so measure these first and work out the additional space you’ll need accordingly. If you want your hatch to span across more than two joists, it’s best to seek the advice of a structural engineer to ensure it is safe.

You can also use timbers as temporary support while cutting, which can be removed later.

Cutting into the Ceiling

Before you start cutting, you should make sure there are no pipes or wires in the area you’d like to cut into. Use a stud, pipe, and wire detectors to be sure. You can also use these to detect ceiling joists and mark them clearly, so you avoid them when cutting. You’ll have to drill enough holes along one edge to get a saw through so you can begin cutting along the lines you’ve marked out.

Finishing Touches After You’ve Made Your Loft Hatch Bigger

Make sure you wipe away any dust or finger marks from your hatch. If you want to paint your hatch to blend in seamlessly with your ceiling, you can use good-quality wood paint to finish the job.
