Replacement windows prices in Maidstone

Here is how the guide price for replacement windows breaks down in Maidstone. We start from national figures and adjust for the South East, which comes out about 12% above the national guide. The resulting range, VAT included, is £5,000–£10,000, and a survey, at no cost to you, firms it up.

Type of jobWhat it usually involvesGuide in Maidstone
One to three windowsReplacing a few problem windows, such as a bay or a rotten kitchen window, in uPVC.£800–£3,400
Whole house in uPVCEight to ten standard uPVC casement windows on a typical 3-bed semi, fitted and finished.£5,000–£8,400
Whole house in aluminium or flush sashPremium frames, colours or period styles across a typical 3-bed home.£8,400–£15,500

The main things that change the figure:

  • Number and size of windows, including bays and large picture windows
  • Frame material, colour and finish, inside and out
  • Glazing type: double, triple, acoustic, obscure or toughened
  • Upper-floor access, scaffolding and the condition of reveals and sills

What does the job include in Maidstone?

  • Made-to-measure frames in your chosen material, colour and style
  • Double-glazed units as standard, with triple glazing as an option
  • Careful removal and disposal of the old frames and glass
  • Fixings, packers, foam and weather seals to suit your wall type
  • New internal trims, external cills and neat sealant finishing
  • Trickle vents, escape hinges and safety glass where regulations require

Flush sashSashes sit flush within the frame for a traditional cottage look, in uPVC or timber.
Sliding sashVertical sliding windows for period homes, in timber or uPVC with authentic details.
Tilt-and-turnOpens inward fully or tilts for ventilation, so upstairs glass is easy to clean from inside.

Local housing and replacement windows

Kent's older buildings include oast houses, weatherboarded cottages, Wealden timber-framed houses and Kentish ragstone walls. Medway towns have long rows of Victorian terraces, Margate and Ramsgate have Regency and Victorian seafronts, and Ashford, Maidstone and Dartford have seen large new estates alongside interwar and post-war housing.

Victorian terraces suit loft rooms and rear extensions; weatherboarded and timber-framed buildings may need cladding repairs and lime work. Newer estate homes often take garage conversions, porches and landscaping.

Building traditions across Kent also raise conservation and planning questions, so we check those for replacement windows in Maidstone at the survey stage.

Permissions for replacement windows in Maidstone

Planning law differs across the UK. For a home in Maidstone, it is the England rules below that count, and we check them with the council ahead of any quote.

Replacing windows and doors on a house is usually permitted development in England when the new ones look broadly similar to the old. Flats, listed buildings and homes covered by an Article 4 direction can need consent, and conservation areas may limit materials or styles.

Replacement windows and external doors must meet Building Regulations for energy efficiency, ventilation and, on upper floors, escape. The work is either self-certified by an installer registered with a competent person scheme or signed off by building control.

Rules change and every property is different, so we check the planning history and constraints for your address before we quote.

How does the job run?

  1. Free site survey

    We begin by looking at the job in person. During the free survey we discuss options, materials and budget for replacement windows, and photograph or measure anything the quote needs to reflect.

  2. Price and scope agreed

    Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.

  3. Booking the work

    Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for replacement windows are in place before the first day on site.

  4. The work itself

    Work goes ahead as scheduled and you deal with one contact throughout. When the last trade leaves, we clear and clean the site, talk you through what has been done and pass on any certificates and care instructions.

Replacement windows in Maidstone: questions

How much do replacement windows cost?

Replacement windows for a typical 3-bed semi cost £5,000–£10,000, depending on the number of windows, frame material and glazing. A single standard uPVC casement usually works out at roughly £500–£950 fitted, while aluminium, flush sash and sliding sash styles cost more. Bays, large panes and upstairs access add to the price. We measure every opening during the survey and give you a fixed price for the agreed specification.

Should I choose uPVC or aluminium windows?

uPVC windows are the lower-cost choice, insulate well and need only occasional cleaning, which suits most houses. Aluminium windows have slimmer frames that let in more light and suit modern homes or large openings, but they cost more. Both come in a wide range of colours and finishes. We usually recommend matching the style and proportions of your home's original windows, especially on period properties.

What happens at the survey?

We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from replacement windows, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.

Who do I deal with during the job?

One point of contact manages your project from survey to handover. They schedule the trades working under our contract, keep you updated on progress, and are the person to call with any question. You don't need to coordinate builders, electricians or decorators separately, because that is part of what we do.

Is triple glazing worth paying extra for?

Triple glazing adds a third pane of glass, which cuts heat loss and outside noise further than standard double glazing. It typically adds around a third to the cost of the glass units and makes opening sashes heavier. It makes most sense on cold or noisy elevations, or in homes being upgraded to a high energy standard. For many houses, modern double glazing with a warm edge spacer gives most of the benefit for less money.
