6 Steps on How to Install Bilco Doors

1. Measure the Size of the Opening

Measuring the size of the opening for your Bilco Doors is an important step before installing them. They should be about two inches smaller than the opening to ensure proper fit. For an accurate measurement, be sure to take into account any framing around the door when measuring its width and height. 

Additionally, you should measure from finished flooring surfaces, such as carpets or tiles, to get an accurate measurement. Aligning a level to the rough opening edges is also recommended to double-check that it’s square. Once you are confident you have the right measurements, you can go ahead with installing your Bilco Doors with ease.

2. Chisel to Level the Area

When installing Bilco Doors, it is essential to check the area with a level first to make sure that it is even and level. Installing the doors on an uneven surface can cause them to not fit correctly and could lead to damage to the door or surrounding structure. 

If the surface cannot be made even using panels, a hammer and chisel can be used in some cases to level the area. Warning: If a hammer and chisel are necessary, ensure you know what you are doing as improper use of either tool could lead to potential injury or more damage to the structure itself.

3. Cut Out the Hole Using a Circular Saw

Successfully installing Bilco Doors requires taking the necessary precautions and measurements. Marking the door opening is a crucial step, as it will give you an idea of how you should go about cutting out the hole. To ensure accuracy, you can use a circular saw or handsaw to create the correct size. 

If your Bilco Doors are meant to be set in masonry, then it’s essential to first drill holes in the surface before attempting to cut using a saw. Following these steps properly ensures that your Bilco Doors will be securely and safely installed into place.

4. Place the Bilco Doors

Installing Bilco doors can be an intimidating task, but with the right materials and preparation, it can be a straightforward job. You will need to carefully place the doors into the opening, then secure them using lag screws and masonry anchors or bolts. 

Using Lag Screws

It is important to align the doors properly during installation – pay close attention to their orientation and use a level to ensure they are level when mounting. Make sure all hardware is tightened securely for lasting performance over time. After installation of your Bilco doors, you’ll have a safe, reliable entrance to your basement or entryway!

5. Check for Proper Alignment

Before installing your Bilco Doors, make sure that everything is properly aligned. Using a level and some string can help to get the frame of your doors exactly the way you need it. Once the first door is taken care of, it’s time to attach fasteners to both sides. 

Make sure that they are in place and tight so that your door won’t budge when opened and closed. If everything looks good after securing the fasteners, then your doors should be ready for installation!

6. Fill Any Gaps Between the Door and Unit

Installing Bilco Doors is an excellent way to keep your home secured and well-ventilated, but even the finest of doors can have flaws. Rain, snow, hail, and extreme temperature changes can cause small gaps between the unit and the opening that could allow moisture to make its way inside. To ensure a proper fit and the highest level of protection, it’s important to fill any spaces with caulk or sealant when you first install your Bilco Doors. 

This simple step will make sure that you don’t experience any unpleasant surprises when you least expect them!

Once you’ve installed your Bilco Doors, you may also want to consider adding a ventilation fan or dehumidifier to help improve air quality and reduce moisture levels in your basement. Additionally, be sure to regularly check on the seals around the doors for signs of wear and tear so that they can be replaced when necessary. With proper installation and maintenance, your Bilco Doors will provide you with many years of reliable use.
