Replacement windows are new frames and sealed double- or triple-glazed units fitted into your existing openings after the old windows are taken out, improving warmth, security and noise reduction while meeting current building regulations.
If you have replacement windows on your list for a property in Greenock, we can help from the first measurements to the final clean-up. For a typical home, plan for 1–2 days on site for a typical house, though larger or more complex jobs take longer. We cover postcodes PA14, PA15, PA16 and PA19 and nearby Helensburgh, Dunoon and Vale of Leven, and every quote we send is fixed for the scope described in it.

Homes in Renfrewshire and Inverclyde
Paisley has sandstone tenements and terraces from its textile era, Greenock and Port Glasgow have tenements and housing climbing the hills above the Clyde, and Gourock and Kilmacolm have Victorian villas. Post-war estates and newer private housing surround the towns, and roughcast is a common finish.
Roughcast and tenement buildings commonly need re-rendering, window replacement and roof work. Villas suit kitchen extensions and landscaping, and semis often take loft conversions and driveways.
That mix of housing shapes how we approach replacement windows in Greenock: the age and construction of your home affect the materials, the method and, in the end, the price.
Planning and building rules in Greenock
Which rules apply depends on where you live. For Greenock, the answer is Scotland, and the points below reflect that; we verify them with the council before quoting.
In Scotland, replacing windows and doors on a house generally needs no planning permission when the style is similar, but listed buildings and conservation areas are closely controlled and often need consent for any change of material or pattern.
A building warrant is not usually needed for like-for-like replacement windows, but the new units must still meet the Scottish building standards, including energy performance and, where relevant, escape from upper floors.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
The four stages
Free site survey
Book a visit and we'll come to you. The survey covers measurements, the state of what's there now and any obvious constraints, so the price that follows is based on your actual home, not an average.
Price and scope agreed
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
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.
Finish and handover
The work is carried out to the agreed specification, with floors and furniture protected and the site kept tidy. At the end we clean up, walk through the finished job with you and hand over any certificates.
What you can expect from us
Replacement windows in Greenock: questions
How long does it take to fit windows in a house?
Fitting replacement windows in a typical 3-bed house usually takes one to two days on site. We take out and fit one window at a time, so each room is weathertight again within an hour or two. Bays, sash windows and homes needing scaffolding take longer. Manufacture comes first: made-to-measure frames typically take a few weeks to arrive after the survey and your order are confirmed.
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.
Do you cover Helensburgh, Dunoon and Vale of Leven?
Yes. As well as Greenock, we cover Helensburgh, Dunoon and Vale of Leven and the rest of Renfrewshire and Inverclyde. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
What happens on the day the windows are fitted?
On fitting day we lay dust sheets, protect floors and furniture near each window, and then remove the old frame carefully to limit damage to plaster. The new frame is fixed, packed, sealed and glazed, and internal trims and external cills are finished. We take away the old windows and clean the glass before leaving. You only need to clear sills and take down curtains and blinds.
Do I need planning permission in Greenock?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Greenock is in Scotland, so Scotland's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
