Window fitting services in Chelsea
Made-to-measure window fitting, doors and roof glazing for period homes, modern extensions and commercial buildings across Chelsea and south-west London. Choose a service below.
Whether you live in a Georgian terrace off the King’s Road, a mansion flat near Sloane Square or a contemporary house with a new rear extension, the right windows make a home warmer, quieter and more secure, and they have to suit the building. Our window fitters survey every property, recommend the style and material that fits both the architecture and your budget, and install everything to a precise, clean finish.
Heritage windows
Sash window fitting in Chelsea
Sliding sash windows define Chelsea’s Georgian and Victorian terraces, garden squares and mansion blocks. We supply and fit heritage-style sash windows that keep the proportions, glazing bars and slim meeting rails of the originals, so the elevation still looks right from the street, while giving you modern double glazing, smooth operation and a proper seal against draughts.
Our Kensington project is a good example: a first-floor apartment in a traditional brick building where the new sashes had to blend into the façade and cure years of draughts, heat loss and awkward operation. We fit sash windows in uPVC and aluminium, with Georgian, Victorian and plain bar layouts and a choice of colours and finishes.
- Heritage-style vertical sliding sash windows
- Georgian, Victorian and plain glazing-bar layouts
- uPVC and aluminium frames
- Double glazing with a draught-free seal
- Sash bay windows and matching upper floors
- Replacements for tired, rattling or rotten sashes
Best for: period terraces, mansion flats and homes in conservation areas.
Windows
Casement and flush casement windows
Casement windows are the most versatile style there is: side-hung, top-hung and fixed panes in almost any combination. We fit standard casements for straightforward replacements, and flush casements, where the opening sash sits flush inside the frame, for a cleaner, traditional look that suits cottages, mews houses and refurbished period homes.
Both come in uPVC and aluminium, with a choice of colours, glazing bars and opening arrangements, including top vents over fixed panes for everyday ventilation. Every window is fitted with multi-point locking hardware.
- Side-hung, top-hung and fixed combinations
- Flush casement windows for a timber-look finish
- uPVC or slim aluminium frames
- White, colour and woodgrain finishes
- Georgian bars and French-style casements
- Multi-point locking hardware
Best for: straightforward replacements, cottages, mews houses and extensions.
Contemporary windows
Aluminium and steel-look windows
Aluminium lets us use slimmer frames and larger panes than uPVC, which is why it is the first choice for contemporary extensions, loft conversions and architect-led refurbishments. Powder-coated finishes, from black to anthracite grey, stay crisp for years with very little upkeep.
For a warehouse or heritage feel we fit steel-look aluminium windows with slim glazing bars in the Crittall style, along with arched and angled windows made to fit unusual openings, like the arched staircase window pictured.
- Slim-profile aluminium casement and fixed windows
- Steel-look (Crittall-style) glazing-bar designs
- Arched and angled windows for unusual openings
- Powder-coated colours including black and anthracite
- Large fixed panes for maximum daylight
- Ideal for extensions, lofts and modern refurbishments
Best for: contemporary interiors, extensions and industrial-style refurbishments.
Windows
Bay and bow window replacement
A bay window is often the focal point of a room, and the hardest window in the house to get right. We replace bay and bow windows as complete units, matching the angles of the existing bay so the frames sit square and weathertight, with sash, casement or fixed panels to suit the property.
On a Victorian terrace in Hanwell we rebuilt the living-room bay with sash-style windows and fitted matching sashes on the floor above, so the whole front elevation kept its period rhythm while the rooms behind it became warmer and brighter.
- Three-, four- and five-panel bay windows
- Bow windows for upper and ground floors
- Sash-style or casement bay designs
- Top vents, side vents or fixed panels
- Matching windows for the rest of the elevation
- Careful removal of the old bay frames
Best for: Victorian and Edwardian houses with original bays.
Windows
Tilt and turn and French windows
Tilt and turn windows open two ways from a single handle: tilt the top inwards for secure ventilation, or swing the whole sash open for easy cleaning from inside. That makes them a practical choice for upper-floor flats and rooms where you can’t easily reach the outside of the glass.
French windows, pairs of casements that open with no central post, give a wide, uninterrupted opening that works beautifully in bedrooms and living rooms facing a garden or balcony. We fit both in uPVC and aluminium, including layouts with fixed top lights.
- Inward tilt for secure, draught-free ventilation
- Full inward opening for cleaning from inside
- Single, double, triple and four-panel layouts
- French casements with no central mullion
- uPVC and aluminium frames
- Fixed top-light options
Best for: upper-floor flats, bedrooms and hard-to-reach glass.
Doors
Bifold, sliding and patio doors
Bifold and sliding doors are the quickest way to connect a kitchen or living space to a garden, terrace or balcony. Bifolds concertina back to open almost the full width; sliding patio doors keep large panes fixed, which maximises the view and helps keep heat in. We’ll help you choose the option that suits how you actually use the room.
In Camberwell we fitted black aluminium bifolds across the back of a brick extension. In Wandsworth a three-panel patio door with two fixed panes delivered maximum light and efficiency. And in a third-floor London apartment we installed full-height bifold doors with a glass balustrade for safety at height.
- Aluminium bifold doors from two to five panels
- Traffic doors for everyday access
- Sliding patio doors in uPVC and aluminium
- Steel-look French and bifold doors
- Heritage slimline doors
- Glass balustrades for upper-floor openings
Best for: kitchen extensions, garden rooms and balconies.
Doors
Front doors, steel doors and internal glazed doors
Your front door sets the tone for the whole house. We supply and fit composite front doors in a wide choice of styles and colours, aluminium and heritage-style doors, and made-to-measure steel front doors, available with or without fingerprint entry for secure, keyless access.
Inside, slim steel and steel-look glazed doors divide kitchens, living spaces and hallways while letting light flow through the house. Side panels, top lights and porches can all be added to suit the entrance.
- Composite front doors with multi-point locking
- Bespoke steel front doors, with or without fingerprint entry
- Aluminium and heritage-style doors
- Internal steel and steel-look glazed doors
- Side panels and top lights
- Porches to shelter the entrance
Best for: new entrances, security upgrades and open-plan interiors.
Roof glazing
Rooflights and roof lanterns
Light from above travels further into a room than light from a wall window, which is why rooflights transform rear extensions, kitchens and top-floor rooms. We supply and install fixed flat rooflights, multiple-rooflight layouts and roof lanterns, usually in aluminium for its slim sightlines and strength.
Every roof is different, so we look at the structure first before recommending a size or position. Recent roof glazing work includes lanterns over new extensions in Guildford and St Albans.
- Fixed flat rooflights
- Roof lanterns for extensions
- Multiple-rooflight layouts
- Rooflights for pitched, tiled roofs
- Aluminium frames with slim sightlines
- Advice on the right size and position
Best for: rear extensions, kitchens, loft rooms and dark hallways.
Extensions
Conservatories and porches
A well-designed conservatory adds a bright, flexible room that connects the house to its garden, while a porch shelters the front door and adds a layer of security. We design both around the proportions and materials of the existing building.
At a house in Richmond upon Thames we built a new conservatory at the rear and replaced every window and door in the property, including a new uPVC door, so old and new glazing was finished consistently across every elevation.
- Conservatories designed around the house and garden
- French doors into the garden
- Replacement windows and doors to match
- Porches with composite or aluminium doors
- Consistent frame colours across the property
- Top-hung vents for airflow
Best for: garden rooms and whole-house glazing upgrades.
Commercial
Commercial glazing, curtain walling and shopfronts
Alongside homes, we work with developers, builders, architects and businesses. On a new four-storey apartment block in South London we supplied and installed sash-style kitchen windows, curtain walling for the living rooms and bedrooms, and balcony balustrades aligned with the façade, delivered in phases over around two months.
We also fit shopfronts, most recently a full-height curtain-walled shopfront in Shoreditch, along with commercial doors, composite fire doors and commercial windows.
- Curtain walling for new builds and refurbishments
- Aluminium shopfronts
- Glass balustrades
- Commercial doors and composite fire doors
- Phased delivery for multi-unit developments
- Work for builders, architects and developers
Best for: developments, shopfronts, offices and apartment blocks.
Time for new windows?
Signs your windows need replacing
If any of these sound familiar, a free survey will tell you whether repair or replacement makes more sense.
Draughts and cold spots
Cold air around the frames, whistling in the wind or rooms that never feel warm.
Condensation between the panes
Misting inside a double-glazed unit means its seal has failed and it has lost its insulation.
Sticking, rattling or loose windows
Sashes that jam, casements that won’t close tightly or locks that no longer engage.
Rotten, warped or damaged frames
Soft timber, flaking paint, cracked seals or frames that have dropped out of square.
Street noise getting in
Traffic, sirens and voices that are easy to hear with the windows shut.
Rising heating bills
Older single or early double glazing lets heat escape much faster than modern units.

uPVC, aluminium or steel?
Each material has its strengths. We’ll recommend the one that suits your building, your budget and how you use the space.

Pricing
What affects the cost of new windows?
No two properties are the same, so we price every job individually after a free survey rather than publishing a one-size-fits-all figure. These are the main things that shape a quote.
Your written quote itemises everything, so you can compare options, such as uPVC against aluminium or double against triple glazing, before you decide.
- Number, size and shape of the windows and doors
- Window style and opening type
- Frame material, colour and hardware
- Glazing: double or triple, acoustic, obscure or safety glass
- Access: upper floors, mansion blocks, scaffolding and parking
- Conservation-area or listed-building requirements
- Removal of the old frames and making good around the new ones
Service FAQs
Questions about our window fitting services
uPVC is cost-effective, low-maintenance and thermally efficient, and it comes in white, colours and woodgrain finishes. Aluminium gives slimmer frames, larger panes of glass and a crisp contemporary look that suits modern extensions and steel-look designs. For period homes a heritage-style sash in either material is often the best fit, and we talk through the trade-offs at your survey.
Yes. We replace single windows and doors as well as fitting complete packages for a whole house, and every item is made to measure for its opening.
Modern double glazing suits most homes and meets current requirements. Triple glazing adds insulation and can help with noise, but it is heavier and costs more, so it is worth it in some situations and not others. We recommend a glazing specification that suits your windows, your budget and the rooms behind them.
Good-quality double or triple glazing, fitted with well-sealed frames, noticeably reduces outside noise, which matters on busy Chelsea streets. One recent customer noticed the drop in noise straight away.
Yes. We fit slim aluminium doors and windows with steel-look glazing bars in the Crittall style, and we supply and install made-to-measure steel front and internal doors, including front doors with fingerprint entry.
Yes. We supply and fit fixed flat rooflights, multiple-rooflight layouts and roof lanterns, usually in aluminium for slim sightlines. We look at the roof structure first before recommending a size and position.
