How We Install Cat Flaps in Double-Glazed Patio Doors

Step 1: On-Site Measurement
We arrange a convenient time to visit your property and take precise measurements of your current glass patio door. This ensures the new unit fits perfectly.

Step 2: Custom Glass Preparation
We cut two new pieces of 4mm float glass, available in plain or patterned designs, to match your current door. A circular hole is precision-cut for the cat flap, and the glass is toughened for safety.

Step 3: Toughening Process
The glass is sent to a specialised toughening plant. This process takes approximately 2-3 days to ensure the glass is compliant with safety standards.

Step 4: Double-Glazed Unit Creation
The toughened glass is crafted into a sealed double-glazed unit, featuring the perfectly positioned hole for the cat flap installation.

Step 5: Final Installation
We coordinate a time to replace your existing glass with the new double-glazed unit. Once installed, the cat flap is securely fitted on-site.


Frequently Asked Questions

Q: Can you install a cat flap in my existing double-glazed patio door?
A: Unfortunately, no. Double-glazed units in patio doors are typically made with toughened or laminated safety glass, which cannot be cut without shattering. A replacement unit is required. We recommend storing the old unit for potential future use to save costs.

Q: I already have toughened glass in my patio door. Can you cut it to install a cat flap?
A: No, cutting toughened glass is not possible as it will shatter into small fragments. A new custom glass unit will be needed.

Q: Can I use any cat flap for my patio door?
A: No, the cat flap must be designed specifically for glass installations and should be circular. While square holes are possible, they are significantly more expensive to cut.

Q: Do you supply cat flaps?
A: Yes, we offer a wide selection of cat flaps, including manual, automatic, and microchip-operated models. We recommend consulting with us to choose the right cat flap for your needs. Visit our site for links to trusted cat flap brands.

Just be prepared to be a bit more patient with older cats who may not have used a cat flap before. Use a food reward for your cat and try playing in close by so they get used to being nect to it. Leave the flap open so they can see outside as curiosity will entice them closer until they eventually go through it. 

Yes you can, if it is single or double glazed, then the glass will need to be replaced by an expoerianced glazier or glass company who can offer you a price for the replacement cost.

No - The glass in the door should already be toughened and you can not cut toughened glass, so we will need to replace the unit (worth hanging on to the double glazed unit we take ut as should you move or need to put this back at a later date will save you some money).
