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. 

No - The cat flap/catflap must be glass fitting and circular as it is very expensive to cut a square hole, although not impossible.

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.

Cat flaps come with a kit that includes a paper template that guides you exactly where to drill. With the help of markings, drill a hole in to each corner of the template. Once you have done with drilling the holes, you can get the shape of your cat flap accordingly. These are great for wooden, UPVC/plastic and metal doors, but would recommend a professionaal for anything to do with glass.

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).

Do You Fit Into Cavity Walls.

We DO NOT install through cavity walls; we recommend that you hire a professional builder for this type of installation.

Cat flap installation in a brick wall has many pitfalls; it is messy, expensive and time-consuming. there may be pipes or wires we can not see.

If this is your preferred route or only option you have for your home, we strongly advise you to consult with a qualified builder before considering installing a pet door through a wall, always ensure they have relevant building experience, qualifications, insurance and that they can comply with all building regulations. 

Yes - as cat flaps come in different sizes, models, automatic etc. it is best to talk to us first in order that you can ask all the questions you require answered on the most popular brands. We offer a selection of cat flaps and pet doors, we highly recommend that you take a brief look at the options prior to making a decision. We have added a link from our site to some of the most popular brands.

By providing a photo of the glass we can give you the exact price. If you are unable to provide a photo of the glass, then kindly provide some rough dimensions. Please measure from edge of glass to edge of glass you can see left to right and top to bottom.
