Steel doors installation typically takes 2-4 hours, while installing a bespoke Stronghold door may require most of the day from 9am to 4pm.

Upon order placement, we usually require 5-8 weeks to process and manufacture your custom security doors, taking complexity into account. However, please note that lead times may vary for certain orders. For an estimated delivery date or to expedite your order, simply reach out to our helpful team. As we have our own factory, we can prioritize your request and strive to deliver your bespoke security doors promptly.

Rest assured, all our security doors are backed by a warranty of at least one year. Additionally, we offer an anti-corrosion guarantee that spans up to 10 years. Should your doors require any alterations or repairs beyond the warranty period, we will gladly evaluate the situation and provide an estimate for any necessary work. We aim to ensure that your doors remain in optimal condition, operating smoothly and providing reliable security.

At Stronghold, we understand that security doors may require maintenance or repairs over time. Our professional technicians are skilled in handling a range of repair services, from minor adjustments to extensive restoration, depending on the level of damage. We recommend us for a thorough assessment and professional repair of your security door. Additionally, to ensure the longevity and optimal performance of your doors, we offer a yearly preventive maintenance service, which we highly recommend. Regular maintenance can help identify and address any potential issues before they escalate, ensuring that your security doors remain in excellent condition for years to come.

The lifespan of a security door can vary depending on factors such as the quality of materials, usage frequency, and environmental conditions. However, a well-made security door is designed to last for several decades. To maximize its longevity and performance, we highly recommend regular preventive maintenance.

We stand out from other brands in the market due to several key factors. Firstly, our own factory gives us a significant advantage in terms of production and turnaround time. With direct access to production, we can ensure efficient manufacturing processes, resulting in quicker delivery of your security doors.

Additionally, our in-house design teams are instrumental in creating the superior quality and craftsmanship that sets our doors apart. Their expertise and attention to detail guarantee that every security door is meticulously designed to meet our high standards.

What's more, all our security doors are proudly manufactured in the UK. This allows us to maintain strict quality control measures and support local craftsmanship. Furthermore, our commitment to sustainability is reflected in our use of responsibly sourced wood, ensuring that our doors are not only secure but also environmentally friendly.

Stronghold security doors are designed to provide exceptional resistance against forced entry attempts. Our doors are equipped with reinforced galvanized steel, which offers robust structural integrity and durability. The multipoint locking system ensures enhanced security by locking the door at multiple points, 4 ways, with at least 11 shoot bolts as standard.

To further strengthen security, our doors feature cylinder defenders, which protect against lock snapping and other cylinder-related attacks. Additionally, we utilize P2B glass, which is triple laminated and glazed, filled with argon gas, and 46mm thick. This advanced glass technology enhances the door's resistance to break-ins.

For customers seeking additional security measures, we offer optional features such as bulletproof doors, providing an extra layer of protection against more extreme threats. Moreover, our biometric system with fingerprint access offers a cutting-edge security solution, ensuring that only authorized individuals can enter your home.

Stronghold security doors are designed to withstand various weather conditions and are suitable for all climates. The outside panels of our doors are made from engineered wood, which ensures that the natural wood quality is preserved while offering excellent weather resistance. This means that our doors won't expand or shrink, even in challenging weather conditions. In fact, they are so weather-resistant that they can withstand exposure to water.

In addition to the engineered wood panels, the steel components of our security doors are galvanized. This galvanization process provides an extra layer of protection against weather elements, ensuring long-lasting durability and resistance to corrosion.

For customers looking for even greater durability, we offer the option of Ruukki steel. This type of steel is four times more durable than standard steel, making it an excellent choice for areas with extreme weather conditions or specific climate challenges.

Stronghold security doors are designed with energy efficiency in mind, offering benefits that go beyond just security. One of the key features that contribute to energy efficiency is the insulation. Our doors are insulated with rock wool, which provides additional insulating value.

Rock wool insulation is a highly effective material that helps to minimize heat transfer. It acts as a barrier, preventing the loss of heat during colder months and reducing heat gain during warmer months. This enhanced insulation helps to maintain a comfortable and consistent indoor temperature, reducing the need for excessive heating or cooling.

Absolutely! Stronghold security doors can be seamlessly integrated with smart home technology, offering you added convenience, control, and peace of mind. Here are the smart features and options available:

Bluetooth Programming: Our security doors can be Bluetooth programmable, allowing you to open and control the door using a dedicated mobile app. This means you can conveniently unlock your door from anywhere in the world using your smartphone, providing flexibility and remote access.

Fingerprint Programming: For enhanced security, Stronghold security doors can be programmed to recognize specific fingerprints. This feature ensures that only individuals with assigned fingerprints can access your home. You can even set specific time frames during which authorized fingerprints are permitted for entry, providing you with precise control over access.

Digital Keypad: If you prefer a code-based entry system, Stronghold security doors can be equipped with a digital keypad. This allows you to enter a unique code to unlock the door, eliminating the need for traditional keys. It offers convenience for family members or trusted individuals who need regular access to your home.
