Questions
Trim Installation FAQs
Can you match my existing trim profile?
Yes — we source matching stock from Long Island lumber suppliers or have a knife ground for unusual profiles.
Do you paint the trim after install?
We can — install + paint quoted as separate line items, or we leave it primed for your painter.
What is the difference between casing and trim?
Casing is the trim around doors and windows; trim is the broader category including base, crown, chair rail, etc.
