An open window overlooking a sunlit field

We have a huge range of windows available, with styles suitable for every property. Our service includes measuring up, manufacture, supply and installation. We take care of the whole process.

A black front door

From PVCU front doors to elegant sliding or bi-fold patio doors, we can make the right door for your home. Our team has been making and installing quality doors for decades – you’re in safe hands.

A conservatory

A conservatory makes a wonderful addition to almost any home, providing extra space and forming a beautiful transition between home and garden. We can design and build one that’s perfect for you.

Just high-quality products, no high-pressure sales

We’re a family run business that has been part of the community here in Southampton since 1986, and we’re one of the largest suppliers of windows, doors, and conservatories in the local area. Our experience and expertise ensure that we can provide exactly what you need.


We know that a lot of people have had negative experiences with glazing companies. Our industry has a reputation for extremely determined sales people, all looking for a signature and a deposit, and reluctant to take no for an answer! We want to change that. We absolutely refuse to engage in pressure selling – we’ll talk to you about your options, offer advice on what may work best for you, and let you know what we can do. Most importantly, we’ll listen to what you have to say – our job is to supply what you want, not tell you what you want.


If you’d like to find out more, please get in touch.

A professional team of friendly experts

We want to make sure that you’re completely comfortable with our team. Every one of our fitters has obtained an MTC card (Minimal Technical Competencies) which means they have passed the criteria to install replacement windows and doors. The MTC is governed by FENSA, a government Authorised Competent Persons Scheme for the replacement of windows and doors in England and Wales.


We are also happy to use our many years of experience to provide you with expert advice on what will best meet your needs – it’s not unknown for people to think they need to spend more than they actually do, and if that’s the case, we’ll let you know. We want you to get the right advice, the right windows, and the right service – all at the right price!

  • How do double glazed windows work?
    Double glazing is where two panes of glass are fitted together with a spacebar in between to form a sealed frame. Argon gas is inserted between the two panes (Argon gas is much denser than air). This stops the warm air inside your home from escaping and shuts out the cold air from entering. Windows By Wise can offer a wide range of `A+` and `A` rated windows to suit your needs. Please get in touch for more details and a FREE quote.
  • What are the benefits of triple glazing?
    Triple glazing is like double glazing, but with an extra pane of glass! It is not just the extra pane that improves your energy efficiency, it is also the added layer of argon gas. Triple glazing is: • Warmer • Quieter • Tougher • Safer
  • Are my windows made to measure?
    Yes, all our windows, doors and conservatories are made to measure, with the exact design and furniture options that you choose. Our team can help you choose the best windows for your home, so please don't hesitate to ask.
  • How quickly can you install my windows?
    After the contract has been signed, we aim to get the surveyor out to you within 2 working days. We will then book a fitting date within 3 to 4 weeks, if you are looking for your windows to be installed on a certain date or quicker, please ask and we will do our very best.
  • Do I need to pay a deposit?
    No, we do not take deposits. Payment is only made once installation has been completed.
  • What guarantees do you provide?
    Windows By Wise offers a 10-year guarantee which is backed by FENSA. The guarantee protects you as a customer against any faulty material with a replacement free of charge. We also provide you with an SAC Security guarantee. If any the windows that we supply and fit, and that have SAC shoot bolt locks, are broken into by forced entry, we will pay up to a maximum of £1000 towards your excess.
  • Are Windows By Wise registered to any governing body?
    We are registered with FENSA and Trust Mark. FENSA was set up by the Glass and Glazing Federation (GGF) and other industry bodies in response to building regulations for double glazing companies in England and Wales. When replacing windows, doors, and roof lights in dwellings in England and Wales, home owners must comply with current thermal performance and building regulation standards and ensure they get a certificate from a competent person scheme such as FENSA. FENSA enables the companies that install replacement windows and doors to self-certify compliance under these building regulations without the need for a separate assessment from building control. Trust Mark is the only Government endorsed scheme for trades in and around the home. Trust Mark awards registered firms with their accreditation after thorough vetting and on-onsite inspections to ensure the firm is raising industry standards.
  • How does self-cleaning glass work?
    Self-cleaning glass is a two-stage process which uses a microscopic coating with a unique dual-action. The first stage of the cleaning process is "photocatalytic". In this stage the coating reacts with daylight to break down organic dirt. The second stage is "hydrophilic". Here, instead of forming droplets, rainwater hits the glass and spreads evenly, running off in a "sheet" and taking the loosened dirt with it, also drying quickly without leaving streaks.
  • Do I need planning permission for a conservatory?
    It depends on what you’re planning – please take a look at our planning permission guidance PDF. This guidance reflects increases to the size limits for single-storey rear extensions which apply between 30 May 2013 and 30 May 2019, and the associated neighbour consultation scheme.
