Frequently Asked Questions

Do Strongdor offer a site measuring service?

No, Strongdor are a supply only manufacturer and therefore unfortunately don't offer site surveys. However we can recommend local installers in your area from our Doorfit Network, who will be happy to help. Complete our quotation request form and mention you are looking for installation and we will put you in touch!

How do I measure a door opening?

To manufacture the best fitting door, Strongdor will require the structural opening (Brick to Brick) of the doorway width and height. We will make the necessary fitting allowances on the size of the door frame. If the opening is wider at the top than the bottom or vice versa, please give us the width at the narrowest point. Expandable sides are provided as standard and give up to 18mm of flexibility each side.

Who is responsible for ensuring the sales quotation meets the specification and building regulations, including location and method of installation?

It is the customer’s responsibility to ensure all details within the sales quotation / sales order meet the exact specification and / or original enquiry and are compliant with current building regulations including location and method of installation. We are here to help and advise. Strongdor cannot accept responsibility for discrepancies after the order is confirmed. All quotes are valid for 30 days from the date of issue. Refer to Strongdor Ltd Terms and Conditions section 2.

What if the door is being installed near the coast or in a corrosive environment?

For any door that is installed within 5km of the coast, we recommend that you talk to one of the sales team about specialist door coatings.

Please ensure you advise our sales team when making your initial enquiry and they will quote accordingly.

You have many different door names on your website - Steeldor, Firedor, Louvidor etc. … How do I know which one to ask for?

There is lots of information about the door properties on the website – especially on the downloadable technical specification sheets. However, if you have any question please do not hesitate to give us a call and speak to one of our door experts. They will be very happy to guide you through the range and assist you in selecting the door that is most suitable for your specification.
