The Elegance Of Wood, The Durability Of Steel

Love the timeless, elegant look of a traditional wooden door, but not too crazy about the maintenance or cost? Fiberglass, an increasingly popular option for home improvement projects, may be the door for you.

Fiberglass doors are usually made up of three important layers: an inner frame of wood, a core of foam, and a skin of fiberglass. Manufacturers can make it so that the door looks like actual wood—just pay a little extra, and not even professionals can tell the difference until they are up close.

With a fiberglass door, you save almost half the cost of a traditional wooden door and you get up to five times the insulation. Given these benefits, the fiberglass door is undoubtedly hard to beat.



Fiberglass doors allow you to choose between a smooth finish and a faux wood grain. With fiberglass entry doors, you capture the beauty, texture, and feel of real wood grain—but without the inherent challenges of wood.


With an inner frame of wood and a core of foam, fiberglass doors are ultimately one of the most energy-efficient choices for an entry door. They offer up to 5X the insulation value of wood, effectively improving your home’s overall energy efficiency.


Regardless of whether it’s painted or stained, all fiberglass doors are able to withstand extreme weather conditions. They won’t fade in direct sunlight or strong rain, are dent-resistant and generally scratch-proof, and are solid enough to resist most wear and tear.


Fiberglass doors require little to no maintenance. Regular, hassle-free cleaning with simple soap and water is all one really needs to maintain a fiberglass door’s wood-like appearance for a good number of years.

"Loved working with Custom Exteriors. Very responsive to inquiries. Precise in their measurements, estimate and timeframe for completion. Highly recommend them."

"Custom Exteriors provided a great product and good service in replacing 2 sliding glass doors and 2 other windows in my townhouse.  One was a custom window that required extra work in refitting the plantation shutters to the new window.  Although there were some bumps along the way, Jeff and his foreman Ryan excelled at follow up.  I would recommend Custom Exteriors."
