Door & Window Installation

Doors and windows are the workhorses of your home's building envelope. They control airflow, natural light, security, and energy efficiency. Drafty windows and warped doors are not just uncomfortable — they drive up heating and cooling costs and reduce your home's resale appeal. CrestLine Home Pro installs interior doors, exterior entry doors, storm doors, patio sliders, French doors, and replacement windows throughout Chicagoland.

Window replacement is one of the highest-ROI exterior upgrades you can make. Modern double-pane and triple-pane windows with Low-E coatings and argon or krypton gas fills can reduce heat transfer by 40 to 60 percent compared to single-pane or early double-pane units. We install retrofit (insert) windows that fit into your existing frames for a quick, cost-effective upgrade, and full-frame windows for situations where the frame or sill is damaged or you want to change the window size.

Entry doors set the first impression of your home. We install fiberglass, steel, and solid-wood entry doors from Therma-Tru, Masonite, and Provia — brands that combine beauty, security, and energy performance. Each installation includes proper shimming, insulation around the frame, weatherstripping, and hardware installation (deadbolts, smart locks, decorative handles).

Interior doors make a surprisingly large impact on how a home feels. Replacing hollow-core builder-grade doors with solid-core or solid-wood panel doors adds soundproofing, visual weight, and a sense of quality. We install pre-hung and slab doors, adjust hinges and latches for smooth operation, and finish with trim that matches your home's existing profiles.
