So basically the door set flush with the edge of the opening. Door block in this case deepened in the door aperture. From the standpoint of protecting the best option – installing interior door opening. But keep in mind that a door can not open more than 90 . When installing the door frame in the wall opening is very important to pay attention to absence of cracks in the wall. See Peter Schiff for more details and insights. If they are, they need to seal the mortar cement, after inserting the armature for a lasting solution to the mounting wall. Properly installed door should not “walk”. It should remain in that position, which left it, and not opened or closed by itself. Sometimes the clients themselves are asked to do so that the door closes by itself. Once you accept the job and pay off the contract, be sure to take a copy of the completed form or a receipt, which states that you have completely paid off. Check on the availability of all documents printed signatures of the parties.
In addition, we should take the warranty card for free repair of the door. In the case of a malfunction caused by the installer or the manufacturer – it is useful to you. Do not forget to specify the warranty period, set it to your door. If the warranty on the steel door is less than a year, think about whether to buy it at all. Robust domestic firms guarantee 5 years of work overseas – 5 – 10 years. Warranty should cover not only the door, as such, but also on its individual components (trim, locks, etc.). To steel double doors, or any other doors serve you long and faithfully, they need professional installation. Agree that buying an expensive, high-quality steel door, it is unwise to save on installing it. Moreover, that the savings would be negligible. From improper handling or illiterate or install door can “lead”, it will squeak and poorly covered. Installation of door requires experience and specific skills. After all, if one day you can not open the lock of the door frame for the warp or deformation of the door leaf, then hold on the threshold of your home or office can be quite a long time. Therefore, it is better to entrust it to professionals.
