Nine services. One specialty.
We do exterior masonry restoration on historic and modern New York buildings — and we do nothing else. The narrower your focus, the better the work. Twenty years of doing the same kind of building has taught us exactly which details matter.
Excelon does exterior work only — facade, masonry, roofing, waterproofing, sidewalk. We do not do interior renovations, kitchens, bathrooms, or framing. The focus is the work, and the work is the focus.
Every service follows the same four-step rhythm .
One direct contact (usually Sajin himself), one written estimate, daily on-site supervision, and a workmanship warranty in writing. No project is too small, no facade too historic.
On-site visit
We come to your building, walk the facade with you, and identify exactly what’s failing — and what isn’t yet. No upselling. Sometimes the answer is “wait two years.”
Itemized estimate
Written, line-by-line, with material specifications and a realistic schedule. You see what you’re paying for, and what’s optional.
Restoration
Daily on-site supervision. Daily clean-up. Photo updates throughout. Sajin or a senior crew member is reachable by phone, text, or email seven days a week.
Walk-through & warranty
Final walk-through together. Punch list addressed before the final invoice. Workmanship warranty in writing — and yes, we come back if something needs attention.
What we don't do — and who to call instead.
Interior renovation
Ground-up construction
New buildings, additions from scratch, foundation builds. We restore; we do not build new.
FISP / Local Law 11 inspections
The inspection itself requires a licensed QEWI architect or engineer. We are the contractor that performs the resulting repairs to spec — and we work with most QEWIs in Brooklyn and Manhattan.
"Resin patch" coverups
We do not paint over rotten cornices or skim cracked brownstone with proprietary resins. The only fix that lasts is the one that addresses the cause.
Not sure which service you
need?
That's our job.
Most facade problems are diagnosed in a fifteen-minute walkaround. We
will look at your building, identify the actual issue, and tell you whether it
needs work now, soon, or not yet.
