uPVC Windows

A uPVC window replacement is a full envelope job, not a swap of the moving parts. We measure the aperture on site, manufacture each frame to the exact opening, then remove your existing windows, prepare the reveals, fit the new units level and plumb, seal them properly inside and out, and hand you the paperwork that keeps the guarantee live.

uPVC Doors

We supply and install made-to-measure uPVC entrance doors, back doors and French door sets. Every door is manufactured to the exact aperture we survey, in the style, colour and glazing you specify, and fitted by our own team — not passed to a subcontractor.

uPVC Conservatories

A conservatory is a full structural project — base, dwarf walls (where required), frame system, roof, glazing, guttering, ventilation and electrics. We handle the design, coordinate the build, install the frame system and roof, and hand you a warm, weathertight room that's usable year-round.

Aluminium Windows & Doors

Aluminium Windows

Aluminium windows are the specification behind almost every architect-led refurbishment and modern rear extension we work on. Thermally broken profiles combine slim frames, huge glass area, exceptional structural strength and any colour you want — a combination uPVC and timber simply can't match.

Aluminium Doors

We supply and install aluminium entrance doors, residential front doors, side doors and glazed rear doors as part of a wider aluminium package or as standalone replacements. Systems are Smart, Aluk or Jack Aluminium depending on aperture, spec and how the door sits with adjacent glazing.

Aluminium Bi-folds

A bi-fold door install is a substantial structural fit. We survey the aperture (including any structural opening work required), specify the correct system for the width and traffic loading, manufacture the door set to millimetre-accurate dimensions, and install it with the precision it needs to slide sweet and lock true.

Patio & Sliding Doors

Sliding patio doors keep the full glass area visible whether they're open or closed — panels slide behind one another rather than folding into stacks. If your priority is uninterrupted views and clean sightlines when the door is shut, sliders win.

Roof Lanterns

A roof lantern is a glazed pyramid or ridged structure fitted over a flat-roof aperture — usually on a rear extension — that transforms the amount of natural light entering the room below. We survey the aperture and structural opening, specify the correct lantern system for the size, supply and install the lantern, and finish flashings and internal reveals.
