How to prepare your home for new windows or doors installation

          Whether you’ve ordered replacement windows or doors, or are a proud owner of a brand new development and awaiting for your bi-fold doors to fill the entire wall opening, there are few things you should know that can help you get through the installation process smoothly and stress-free.


Before our Window Installers Arrive:

  • Our Customer Service team will have been in recent contact and scheduled your installation date with you. If anything is unclear or you require any additional information, please do not hesitate to contact our Customer Service team.

  • Meet your builder and walk through your home with them and discuss each window/door. Identify any areas you will need to clear to allow us access to install your products.

  • Ensure that any items that you have been asked to provide are ready. This is your opportunity to ensure your property is ready for your installation exactly as required.

  • Remove any obstacles and ensure clear access to the area of installation. Make sure that our Installation team has plenty of room to work when they arrive. Remember: we will need to move the products around before they are installed. You might want to remove your lampshades too.

  • Bi-folds are normally fitted to an external wall, so remove any toys, potted plants or other items that normally sit on the patio.

  • Make sure that the installers can get access to the wall in question, with a good clearance on all sides. If this is a bulky item, ideally, it’s best to empty the room.

  • Make sure that the Installation team have a clear path to the front door (and the door is unlocked when they arrive!). Remember to make provisions for your pets, either locked in a room or kept safe on a leash.

  • You should also clear some space outside for their equipment and have a place set aside for the vehicles they will arrive in. If necessary, we will need you to arrange a parking permit.

  • Do you have any unique needs? Just in case you can put some reminders in place, for example Post-It Notes on the wall next to the windows to be replaced, specifying special instructions, like "Please save old window."  


  • Our installation Engineers will measure the openings on arrival to ensure all products are suitable for the apertures prior to commencing fitting.

  • Remember, power tools need power, so make sure you point out the outlets that can be used the first day of the job.

  • Our team brings in their own drop-cloth/ dash sheet to secure the floor and furniture in the area. Any bulky objects, furniture and flooring in the area of the installation will be covered, though please make sure you’ll secure the items of value.

  • Walk through your home on your own to ensure that our Installation Engineers have put down drop cloths inside and all your valuables are protected.

Other things to remember

window fitters using specialist crane          Having windows replaced will cause some draughts in your home. The bigger the opening, the more draughts you will get whilst work is in progress. Make sure you stay warm - especially if you have young children at home. This is particularly important, as it can be up to an hour before the new windows will be fitted, after the old one is removed, so please bear with us. Our Installation Engineers are working as efficiently as possible.  Often, our Installers will make an opening for your bi-folds and prop the wall using special equipment. These props may need to be in place for a day or so. Please ensure that children and animals are prevented from accessing the area; props are safe, but should not be tampered with under any circumstances.

Will the window installation team tidy up?

          Be prepared for the mess that installation is likely to cause. Especially, in case of replacement windows. Removing old windows and putting in new ones involves plenty of sanding and stripping; often window replacement procedures also require priming and painting, too. These activities will allow paint (dry, wet, or both) and dust to fall on your floors and the outdoor areas underneath the windows. Our teams are always careful and always tidy up after the job is completed. They will broom-clean and hoover your home in the areas they have worked once they have tested your new products.  Though keep in mind that it will take few hours for the dust to settle and finding the thin layer of dust after we leave is unfortunately unavoidable. 

How long will it take to get my replacement windows fitted?

          The type of window being installed and type being removed help determine the amount of time needed to complete your installation. On average each window takes about 1 – 2 hours and fitting the bifold doors up to 5 hours (approximately 1.5 hours per panel). Trim work and clean-up will add to that time. Overall, an average job will take a single day.

          If you have a home office, ask the Installation Engineers to address that room first, allowing you to get on with your work as early as possible.

Should You Stay Home?

          Yes. If you can take time off from work or can work from home, do so.  This is important as we will need to demonstrate the operation of your products and check all works with you once we have completed. This enables us to ensure everything is to your satisfaction. Entire house window installation is highly invasive, affecting every room of your house.  We will assure you that you do not need to stay home all day, but this is always a good idea to keep work in line and to make sure that all the areas are protected and installation goes smoothly. If you cannot be home when your windows are replaced to check the installation, be sure to make arrangements with your contractor so we can gain access to your home in your absence and they can sign off our work on completion. Please make sure that the decision maker or the builder/foreman is available on site.

What happens to my old windows?

          After installing your new windows or doors, we remove all the old items from your property and dispose of them as environmentally friendly as possible. If you wish to keep your old windows or storm windows, please notify the installation Engineers as soon as they arrive to complete your installation. Please note that depending on the work it may not be possible for you to keep your existing products as they could be unavoidably damaged when removed.

What do I do if there is a problem with the windows?

          Most of the issues encountered by our customers are easily corrected and don't necessarily mean that there is a problem with your window or door. You are always welcome to contact our Customer Services department for assistance on 0208 961 6111 or by noting your issue on our Installation Engineers Completion document after they have demonstrated the products to you.

          Once your doors and windows are in place our installers will tidy up your home and they’ll talk you through the security features. If you’re unsure how to use the bi-folds, or other installed products, don’t hesitate to ask for guidance. In particular, make sure you understand how to use the locks. We recommend that you choose a safe place for keys from day 1, and never leave keys dangling in the door.

          Our installers will also talk you through basic maintenance, especially when it comes to bifolds or sliding doors, such as clearing grit from the runners and ensuring the doors run freely on the tracks. Feel free to ask our Installation Engineers to explain this to you. Generally, a quick vacuum once a week is enough to keep the runners in good condition.

          Getting your house ready for replacement windows or brand new doors can take a little time, but it will definitely make the process go more smoothly.

         Oh, and remember to keep your dog on a leash that day!
