Cat Flaps Fitted in Glass in Northolt
Want a cat flap in a double-glazed door or window?
Existing glazing can’t simply be cut — the sealed unit has to be replaced with a new one made with the hole already in it. That’s exactly what we do: measure up, order the unit, and fit your flap neatly and weathertight. Local, family-run glaziers.

FAQs
Cat Flaps in Glass in Northolt — Your Questions
Can you cut a cat flap into my existing double glazing?
No — toughened sealed units can’t be cut once they’re made. We measure your opening, order a brand-new unit with the hole already cut, and fit it with your flap. It’s the only safe way to do it.
How long does the job take?
Once the new unit arrives — usually a few days — the fitting itself is typically a single short visit.
Do you supply the cat flap?
We can supply one, or fit a flap you’ve already bought. Just let us know the make and model.
Will it affect my insulation?
No. The new unit is made to the same specification as your existing glazing, so insulation and sealing are unaffected.
Can you fit one in a patio door or back door?
Yes — we fit cat flaps in windows, patio doors and glazed back doors.
