Window, Door & Curtain Wall Repair Services

Practical repair, restoration, and performance upgrades for existing buildings — helping property managers, condo boards, and owners extend the life of their windows, doors, glass, and façade systems.

Repair-first. Replace Later.

Many window & door problems can be corrected without full replacement.

Fenestra saves owners money by replacing hardware and weatherstripping, returning windows and doors back to (or beyond) original air & water tightness

- Lower cost
Typically, repair options are a small fraction of the cost of full replacement.

- Less disruption
Compared to full replacement, Fenestra's repairs are faster and less invasive. And your blinds will still fit.

- Extend service life
Fenestra customers can often delay full replacement several decades.
