Surrounds are, simply put, the decorations that can be added to each side and above your door to create nearly any look you choose.

Add glass panels, stained glass, iron designs, solid panels, or nearly any design you can imagine to enhance the beauty of your entryway.

We work primarily with Fypon surrounds because of their high quality and classic designs.

Fiberglass Entry Doors

Fiberglass entry doors are a great alternative to wood or steel. They’re energy efficient, easy to maintain, secure, and much more durable as their counterparts. We work with Therma Tru, the inventor of the fiberglass door, who offers several types of door, which includes several collections of doors with various types of authentic wood grain looks from oak, mahogany and smooth finishes .

Exterior Door Systems

Storm Doors

A storm door is designed to be installed in front of an entry door or other door that may become damaged by the elements. The aluminum-and-glass construction protects your primary entry door, and allows additional ventilation in your home during warm months with the unique Pella Rolscreen design option. They securely lock, offering protection while your entry door is open.

Patio Doors

Lake Cook also provides patio doors from  Simonton and Park-Vue who offer beautiful French patio doors that add character to a any room as well as sliding patio doors and patio doors with internal raise and lower blinds to protect your floor, carpets and furniture from the hot summer sun.

Stainable or Paintable Exterior Doors

You may purchase entry doors that are 100% ready for use, or a plain door that you can paint or stain any desired color. Your options are literally endless when you buy a door you can stain or paint yourself. Too busy to paint? No problem, Lake Cook can even offer in-home customer door finishing for you! You pick the paint or stain, and we do the work, it's that easy.
