Frequent questions
Can I see the hardware in person before I book?
Yes. Come by the showroom and look at the hardware in person before you book a planned visit.
Does the grand opening discount cover a planned visit?
For a planned visit, one tier applies, 20, 15, or 10 percent, only when the offer-terms page matches the scope. One offer per job. See the offer-terms page for the full list, valid through December 31, 2026.
How do I reach the shop?
For a planned visit, call (202) 900-5625 or email capitolsentinel@gmail.com. Directions and hours are on the contact page.
What should I bring?
For a planned visit, bring photos of the opening and a phone number that reaches you. Showroom hours and the 24-hour emergency line are different, and Monday visits are by appointment.
