This guide explains double glazing cost in Wimbledon Chase, so you can plan a budget before you book a survey. It is for owners who want to know what drives the price of windows, doors, conservatories and roof lights. You will see our starting prices, what moves a quote up or down, and how to compare quotes fairly.
Every job gets a written, fixed quote after a free survey. Our fitters are FENSA registered, and each job comes with a 10-year guarantee. For the town-wide guide, see our main double glazing prices page.
What shapes glazing prices in Wimbledon Chase
Local homes and streets have a real effect on cost. The age of the house sets the style and size of the frames. Access sets how long the fitting takes.
- Typical homes: Interwar semis and terraces, with some newer flats near the station
- Postcodes we cover: SW20
We price each home on what we find at the survey, not on a rough rate per window.
Starting prices for common jobs
These are entry prices for a standard job. Your quote may be higher or lower once we see the openings.
- uPVC casement window: from £400 fitted.
- Sliding sash window: from £650 fitted.
- Composite front door: from £1,200 fitted.
- Bifold doors: from £3,200 fitted.
- Conservatory: from £8,500 fitted.
- Skylight or roof light: from £750 fitted.
Each starting price covers a frame of a common size in a standard finish, with A-rated glass, removal of the old frame and a tidy finish inside and out. It does not cover structural work or large repairs.
What drives the price of windows
Windows make up most of the spend on a typical house. Five things set the price of each one.
- Size: bigger frames need more material and more glass. Very large panes may need thicker glass or a stronger frame.
- Style: plain casement windows cost the least. Sash, flush casement, bay and bow windows take more work to make and fit.
- Material: uPVC is the lowest cost. Aluminium costs more for its slim frames. Timber is often the dearest, but it may be needed on period homes.
- Colour and finish: white is the base price. Colours, wood-grain foils and a different colour inside and out add to the cost.
- Glass: our standard 28mm unit has low-E glass and argon. Acoustic, obscure, toughened or triple glazing each adds a little.
What drives the price of doors
A door is a bigger part than a window, with more hardware, so it costs more per opening.
For a front door, the main costs are the door slab, the glass design, the hardware and any side panels. A composite door with a solid core costs more than a uPVC panel door, but it is stronger and keeps more heat in.
Bifold and sliding doors cost more again. They have wide panes, heavy glass and long runners. The opening also needs a sound lintel above. If we need to widen the opening or fit a new steel beam, that adds to the cost. We list it as a separate line so you can see it.
Conservatory and skylight costs
A conservatory price depends on the size, the shape and the roof. A small lean-to costs far less than a large P-shape. Solid and tiled roofs cost more than glass roofs, but they keep the room warmer in winter and cooler in summer. The base, dwarf walls and any drainage work also count.
For roof lights, the cost depends on the roof. A window in a pitched tiled roof is quicker to fit than a large flat-roof light. Loft work may need extra framing, insulation and plaster. Higher roofs need a tower or scaffold, which adds to the price.
Access, making good and other extras
Some costs only show up once we see the house. A good quote names them up front, so you are not surprised later.
- Access: upper floors may need a tower or scaffold. Tight streets can add time on the day.
- Making good: new cills, plaster repairs or fresh trims around the frame.
- Structure: a failed lintel or rotten timber found when the old frame comes out.
- Disposal: taking away and recycling the old frames and glass.
- Alarm sensors: refitting window or door contacts.
Where something cannot be checked until the old frame is out, we list it as a provisional sum. We explain what it covers and agree any change with you before we do the work.
Which homes in Wimbledon Chase cost more to glaze
Older homes often have openings that are out of square, so each frame needs more care to fit well. Period terraces may need sash or flush casement styles to keep the street look, and those cost more than plain casements. Bay windows need new posts and a fresh roof cover in many cases.
Newer homes in Wimbledon Chase tend to have standard sizes and good lintels. They are often the quickest and lowest cost to glaze. Flats can add cost if the frames are high up or the building has rules on style and colour. We point out these factors at the survey, so the quote reflects your home.
How to compare quotes fairly
A low price is not good value if the quote leaves things out. Lay your quotes side by side and check each one names:
- The frame brand, profile depth and colour.
- The glass spec, such as 28mm, low-E and argon filled.
- The lock type and whether it meets PAS 24.
- What is included for cills, trims, making good and disposal.
- The guarantee length and who backs it.
- That the firm is FENSA or Certass registered.
Be wary of firms that offer a large discount if you sign on the day, or that ask for a big deposit before any work is made. A fair quote stays open long enough for you to think it over.
How we price your job
We start with a free survey at your home. We measure each opening, check the walls and lintels, and talk through the styles and glass that suit you. Then we send a written, fixed quote with each item on its own line. Payment stages are set out in the quote, so you know when each one falls due.
The full process, from survey to aftercare, is on our how we work page. When you are ready, you can book your free survey and quote. You can also go back to our Wimbledon Chase home page or our page on double glazing across Merton.
Frequently Asked Questions
Why are the prices on this page only starting prices?
No two homes are the same. The size, style, access and state of each opening all change the price. A starting price tells you where a standard job begins. Your real cost comes from the survey, where we measure every opening and check the walls. You then get a written, fixed quote that will not go up unless you change the spec.
Is it cheaper to replace all the windows at once?
Often, yes. A larger job lets us make all the frames in one run and fit them in one visit. That saves time on set-up, access and travel. But you do not have to do it all at once. We list each window on its own line, so you can start with the worst rooms and finish the rest later.
How long does it take from survey to fitting?
After the survey and your go-ahead, we confirm sizes and place the order. Standard white uPVC frames are quicker to make than colours, timber or bespoke shapes. We give you a fitting date when we place the order. Most houses are fitted in one to three days, depending on the number of frames and any repairs needed.
Can new double glazing affect home insurance or the value of the house?
New locked windows and PAS 24 doors can help with home security, so tell your insurer when the work is done. Buyers also look for modern glazing and a valid FENSA certificate. Keep your certificate, your guarantee and the spec of each frame together. A buyer's solicitor will ask for them, and missing paperwork can slow a sale.
What care keeps the guarantee valid?
Clean the frames and glass with warm soapy water and a soft cloth. Do not use harsh or abrasive cleaners. Oil the hinges and locks once a year. Keep the drain slots clear. Do not drill into the frames or add film to the glass without asking us first. If something goes wrong, call us rather than using another firm.
