What windows and doors do you offer?
The product range covers most of what homeowners in Greenock ask for. Whether your priority is cutting heating bills, improving security, or simply refreshing the look of your property, there is something in the range to suit.
- uPVC Windows, double or triple glazed, available in a range of frame colours and styles

- uPVC Doors, a practical and cost-effective option for front and back entrances
- French Doors, ideal for opening up a living room or kitchen to a garden

- Front Doors, available in composite or uPVC, with a range of panel designs and glazing options
- Triple Glazing, for homeowners who want maximum thermal performance and reduced outside noise
- Conservatories, designed and fitted to match the style of your home
All products are fitted with multi-point locking systems as standard. The frames and glass units are low-maintenance, meaning no painting, no warping, and no rot over time.
What energy ratings do your products carry?
The windows and doors fitted by Greenock Windows And Doors carry an A energy rating. That means your home retains more heat in winter and stays cooler in summer, which makes a real difference to your fuel bills across the year.
The glazing units use argon-filled cavities between the panes, and the uPVC profiles are multi-chambered to reduce heat loss through the frame itself. It is not just about the glass. Every part of the unit is designed to hold warmth in.
How long does fitting take?
From the point of placing your order, installation is typically completed within ten weeks. Most jobs, depending on the number of windows and doors being replaced, are finished within a day or two once the fitting date arrives.
Your home will be left clean and tidy at the end of each day. The team works efficiently and respects the fact that this is your home, not just a worksite.
What guarantee do I get?
Every product installed by Greenock Windows And Doors comes with a full ten-year guarantee. This covers the frames, glass units, and hardware, so you have proper protection long after the fitting is done.
The guarantee reflects the quality of materials used. These are not budget products. The frames, sealed units, and locking mechanisms are all built to last, and the ten-year cover gives you confidence in that.
Do you provide free quotes?
Yes. Getting a quote costs nothing and commits you to nothing. One of the team will visit your home in Greenock, take accurate measurements, and talk through your options at a pace that suits you.
There is no pressure to make a decision on the day. If you need time to think things over or get other quotes, that is completely fine. The goal is to make sure you feel comfortable with what you are choosing before any order is placed.
Why do homeowners in Greenock choose us?
A lot of our work comes through word of mouth. Customers who have had their windows and doors fitted by us tend to recommend us to neighbours and family, and that tells you something about the standard of work carried out. The reviews speak for themselves.
We are fully insured, every staff member and trade partner is experienced, and your project is managed from the initial survey right through to the final tidy-up. You will always have a direct point of contact if you have questions along the way.
