Frequently asked questions

  1. We would arrange to visit your home or property at a convenient time to get an exact measurement of the current double glazed unit in the door, check what pattern you have and offer a like for like or an alternative if the glass is no longer manufactured.
  2. We would then cut 2 new pieces of 4mm float glass (plain or pattern of your choice) to the exact size as measured, cut a hole in both pieces of glass for the cat flap and then have the glass toughened. (What is toughened glass).
  3. Approximately 2-3 day later the cat flap glass will be ready to collect from the toughening plant.
  4. We will then create a sealed doubel glazed unit which will have the hole perfectly placed for the installation of the cat flap.

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.

It varies, but usually takes around 1 hour to install a cat flap in wood, UPVC, metal or a composite door, if it is a cat flap in glass or a double glazed unit, the glass will be toughened safety glass and usually take 3-5 working days to remanufacture and about 30 minuites to install again subject to type and style of door or frame.

We can only offer our prices whish are below

A half panel door approx 60cm x 60cm would be £245 - £325 + Vat (£290) (clear glass - supplied and fitted subject to view)

A full height door panel approx 190cm x 60cm would be £325- £495 + Vat (£390) (clear glass - supplied and fitted subject to view)

if it has lead on the glass, a coloured glass or geogian bars, there would be an increase in the prices as above, this is why its best to send a picture and we can confirm the cost 100%

We're afraid not as the glass is already toughened when you try to cut it and the glass would break into hundreds of thousands of pieces!
