Cat Flap Installation Services

We specialise in professional cat flap and pet door installation for all door and window types. Whether you need a microchip cat flap fitted in a glass patio door, a SureFlap installed in a UPvc back door, a pet door cut into a composite front door, or a cat flap in a window — our experienced installers deliver a clean, secure and weatherproof finish every time.

We cover North West England, Cheshire, Staffordshire and North Wales — including Manchester, Liverpool, Chester, Warrington, Stockport, Wirral, Crewe, Stoke-on-Trent and Wrexham.

Glass Door Cat Flap Installation

Specialist cat flap fitting for glass patio doors, French doors, sliding doors and side panels.

We cannot cut into your existing glass — a brand-new toughened glass panel with the cat flap hole pre-cut is required. We arrange the new panel, professionally fit it into your door frame and install the cat flap for a seamless, weathertight finish. This applies to single and double-glazed panels, patio doors, French doors, bifold doors and side panels. Popular brands for glass installations include Pet-Tek and SureFlap with their round mounting adaptors.

Suitable for patio & French doors

UPvc Door Cat Flap Installation

The most popular and affordable cat flap fitting — quick, neat and energy efficient.

UPvc doors are the most common type we work with. We cut a precise opening in your UPvc door panel, fit the cat flap securely and ensure a weathertight seal that maintains your door's insulation. The installation is quick (usually under an hour) and your door will look as good as new. All leading brands fit UPvc doors including SureFlap microchip cat flaps, PetSafe and Closer Pets.

Composite Door Cat Flap Installation

Expert cat flap fitting for modern composite front and back doors.

Composite doors are built tough with multiple layers of GRP, foam insulation and timber, so fitting a cat flap requires specialist tools and knowledge. We carefully cut through each composite layer without compromising the door's strength, security or weather resistance. The result is a clean, professional fit every time. All major cat flap brands can be fitted into composite doors including SureFlap, PetSafe and Closer Pets.

Wooden Door Cat Flap Installation

Cat flap fitting in solid timber, engineered and traditional panelled wooden doors.

Wood is straightforward to cut and unforgiving if it's left unsealed. We position the aperture clear of the door's structural stiles, cut cleanly so there's no splintering on either face, then seal every exposed edge before the flap goes in so the timber can't swell or rot. Suits solid oak and pine back doors, Victorian and Edwardian panelled doors, stable doors and painted garden doors. Fire doors are the one exception — we never cut those.

All cut edges sealed against moisture
Splinter-free finish inside and out
Panelled, stable & solid timber doors
From £60 (fitting only)

Bi-Fold Door Cat Flap Installation

Cat flaps in aluminium and uPVC bi-folds using a brand-new pre-cut toughened unit.

Bi-fold panels are toughened, and toughened glass shatters if cut — so we never touch the existing glass. We measure the panel, order a brand-new toughened double-glazed unit with the cat flap aperture cut before toughening, then swap it in. The flap normally goes in the fixed or traffic leaf so it isn't swinging out of position every time the doors open. Track, rollers and folding action are completely unaffected.

New toughened unit, glass spec matched
Track, rollers & hardware untouched
Best leaf chosen for daily cat access
From £280 including the new pane

Aluminium Door Cat Flap Installation

Origin, Smart Systems, Aluk, Schuco and older aluminium frames.

We never cut an aluminium frame — it's structural and usually thermally broken. Instead there are two routes. Fully glazed aluminium doors get a brand-new toughened double-glazed unit with the aperture pre-cut, swapped into the same panel. Doors with a solid infill panel are cut directly, reinforced and sealed, and can usually be completed in a single visit.

Frame and thermal break never cut
Glazed and solid infill panels both covered
Weathertight seal & drainage checked
From £60 (panel) or £280 (glass)

Sliding uPVC & Aluminium Door Cat Flap Installation

Cat flaps fitted into sliding patio doors without cutting the existing toughened glass.

Sliding uPVC and aluminium patio doors are usually fully glazed with toughened glass, which can't be cut on site. We measure the panel, order a brand-new toughened unit with the cat flap aperture pre-cut, then swap it into your existing frame. The sliding track, rollers and locking hardware are left untouched, so the door still glides and locks exactly as before. It's the neatest, strongest way to give your cat access through a sliding door.

Sliding track and rollers untouched

Window Cat Flap Installation

Cat flap fitting for double-glazed, triple-glazed and single-glazed windows.

If you'd prefer your cat flap in a window rather than a door, we can help. Just like our glass door installations, we supply a brand-new toughened glass panel with the cat flap hole pre-cut, then professionally fit it into your existing window frame. This is a great option if your doors aren't suitable or you'd rather keep your doors cat-flap-free. Works with kitchen windows, utility room windows, side panels and conservatory windows. All leading brands including SureFlap and Pet-Tek can be fitted into window panels.

New toughened glass panel supplied & fitted
Ideal when doors aren't suitable
Works with double & triple glazing
Keeps your doors untouched

Dog Door Installation

Professional dog door fitting for all door types — sized for your breed.

We install dog doors and large pet doors in UPvc, composite and glass doors. Whether you have a small terrier or a large Labrador, we'll recommend the right size door and fit it securely with a weatherproof seal. Popular brands for dog doors include SureFlap Microchip Pet Door, PetSafe and Pet-Tek.

Sized for small, medium & large dogs
All door types — UPvc, composite & glass
Weatherproof & secure fitting
Microchip options available

French Door Cat Flap Installation

Cat flap fitting in French doors — into a brand-new toughened panel, never the frame.

French door glass is toughened, so it can't be cut. We measure the pane, order a brand-new toughened unit with the cat flap aperture pre-cut and the spacer bar routed around it, then fit it into your existing frame. The flap normally goes in the passive (bolted) leaf so your main opening door is left completely untouched, and the multi-point lock and hinges are checked before we leave.

Fitted into the passive leaf
New toughened panel, sealed unit intact
uPVC, aluminium & timber French doors
Georgian bars and obscure glass matched

Microchip Dog Door Installation

Pet doors that only unlock for your dog — no foxes, no strays.

A microchip dog door reads your dog's existing microchip or a collar tag and stays physically locked to everything else. We size it to your breed, position the aperture to keep the panel strong and fit it into uPVC, composite, wooden or glass doors. Larger breeds get a full-size pet door with collar-tag or manual 4-way locking.

Conservatory Cat Flap Installation

Cat flap fitting for conservatory windows, doors and side panels.

Conservatories are a popular choice for cat flap installations. We can fit a cat flap into conservatory glass panels, UPvc doors or windows — giving your cat easy access to the garden without leaving your main house doors open. We supply new toughened glass panels where needed and ensure a draught-proof, secure finish.

Fits conservatory glass, doors & windows
New toughened glass panel if required
Draught-proof & secure
