Quality uPVC Windows Installed Across Surrey & South London

If your windows are draughty, discoloured or just won’t open properly any more, you’re not imagining it. uPVC frames wear over time, especially in older homes around Surrey and South London that still have the same windows after 20 years or more.

We’d rather talk you through what actually needs doing than sell you the biggest package we can. Sometimes that means replacement uPVC windows. Sometimes a repair is all you need. We handle the whole job either way: survey, manufacture, fitting and the paperwork that comes with it.

Upvc Windows

What Are uPVC Windows?

uPVC stands for unplasticised polyvinyl chloride. It’s a tough, weather-resistant plastic that’s used to make window frames instead of timber or aluminium. It doesn’t rot, it doesn’t need repainting, and it holds its shape in conditions that would warp or split wood.

uPVC has been used in British homes for decades because it’s affordable, energy-efficient and long-lasting. A well-fitted set of frames can last 25 to 30 years.

Why Choose uPVC Windows for Your Home?

Energy Efficiency & Lower Heating Bills

A worn or poorly sealed window is one of the quickest ways to lose heat, however good your boiler is. Modern uPVC windows with low-E double glazing keep the warmth in, and depending on what you’re replacing, you may notice a real drop in your heating bills. Most people feel the difference in the first cold snap.

Security & Multi-Point Locking

Our uPVC windows come with multi-point locking, so the frame is secured in several places instead of relying on one latch. Add reinforced frames and toughened glass options, and it’s a big step up from older single-lock windows.

Low Maintenance & Long Lifespan

No sanding, no repainting, no filling cracks where the timber has swollen. A wipe-down now and then is all a uPVC frame needs. That’s a big reason they’ve stayed so popular. Nobody wants to repaint window frames every few summers.

Noise Reduction for Busy Roads & Urban Areas

If you live on a main road in Croydon, near the railway in Sutton, or anywhere with more traffic than you’d like, this matters. uPVC frames with double or triple glazing won’t silence the outside world, but they’ll take the edge off it. You’ll notice the first evening you sit in the room with the windows shut.

Our uPVC Window Styles

uPVC Casement Windows

Casement Windows

The most common style in the UK, and for good reason. They’re practical, affordable and suit almost any property. They hinge at the side, open outwards and are easy to clean from inside.

uPVC turn and tilt windows

Tilt & Turn Windows

These open inwards in two ways: tilted from the top for gentle ventilation, or swung fully open on a side hinge for cleaning. They’re a good fit for flats and upper floors, where safety and easy cleaning both matter.

uPVC Bay and Bow Windows

Bay & Bow Windows

A bay or bow changes the feel of a room. It pushes the space outwards and lets in more daylight, and it’s one of the most noticeable upgrades you can make to the front of a house.

upvc Sliding Sash Window

Sliding Sash Windows

If you have a period home and love the classic vertical-sliding look, uPVC sashes give you that without the draughts and rot of old timber. They’re popular in parts of Surrey with older, character housing, where planning rules sometimes apply.

uPVC Flush Sash Window

Flush Sash Windows

A more contemporary take, with the sash sitting level with the frame. It’s a good choice if you want the character of timber windows with the low maintenance of uPVC.

Our uPVC Window Installation Process

Good windows only perform if they’re fitted well. That’s why we look after every step of uPVC window installation ourselves.

1. Free Home Survey & Quote

We come out, look at what you have and talk through your options honestly, including telling you if you don't need a full replacement. You get a clear quote with nothing vague hidden in the small print.

2. Made-to-Measure Manufacturing

Every window is made for your specific openings, not a standard size. It matters more than people think. A badly fitted window undoes most of the energy and security benefits you're paying for.

3. Professional Fitting

Our installers remove your old windows, fit the new ones, and seal and finish everything properly, so there's no draught creeping in round the edges months later.

4. Aftercare & Guarantee

Once we've finished, you're covered by our guarantee. If something isn't right, we come back and sort it. We're not a company that disappears once the invoice is paid.

uPVC Window Repairs in Surrey & South London

Not every window problem means starting again. If your frames are still in decent shape, uPVC window repairs can save you a lot of money, and we’ll tell you honestly which route makes sense.

Here’s what we can usually put right:

  • Misted or failed double-glazed units: condensation between the panes means the seal has gone. We can often replace just the glass and keep your frame.
  • Broken handles, hinges and locks: we repair or replace worn hardware so your windows open, close and lock properly again.
  • Worn seals and draughts: we replace perished gaskets and realign sagging sashes.
  • Sticking or dropped windows: we adjust or replace the parts that stop them closing cleanly.

If you’re wondering whether to repair uPVC windows or replace them, the frames are the deciding factor. If they’re warped, cracked or badly discoloured, replacement will usually be better value in the long run. If it’s just the glass or hardware, repair is often the smarter move. We’ll take a look and give you a straight answer.

What Our Customers Says About Us

Frequently Asked Questions

It depends on the style, size and number of windows. A single casement costs far less than a full-house refit with bay windows. Get in touch for a free survey and we’ll give you an honest, itemised quote rather than a vague ballpark figure.

A like-for-like replacement of a single window can often be done in a day. A whole house usually takes a few days, depending on how many windows you’re having fitted and whether any work is needed around the openings.

We supply casement, sash, tilt & turn, bay & bow and flush sash windows, in a range of colours and finishes, including woodgrain effects for period homes. If you’re not sure what suits your house, we’ll talk it through at your survey.

Often they can be repaired. Misted glass, worn seals, faulty handles and sticking sashes are all common fixes. If the frames themselves are badly warped, cracked or discoloured, replacement may make more sense. We’ll inspect them and tell you honestly.

Yes. Every installation comes with a guarantee covering both the product and our workmanship, so if something isn’t right, you’re covered.

Yes. uPVC frames with double or triple glazing cut outside noise noticeably compared with older single-glazed windows. Triple glazing is worth considering on busy roads.
