When old window trim is the whole problem
Point 1
Built to your opening, not a catalog corner box.
Older North Jersey homes have odd sill widths, deep returns, and layers of old trim. Our crew brings PVC board stock to your house, measures each window by hand, and cuts every piece on site. No factory-welded unit shipped for an average size that does not fit your wall.

Point 2
New surrounds without tearing off your siding.
Retrofit trim ties into your existing J-channel, head flashing, and siding field. We work at the openings while your vinyl, aluminum, or Hardie walls stay in place when they are sound. That is how homeowners refresh curb appeal without a full exterior remodel.

Point 3
AZEK and Restoration Millwork, quoted by name.
Both are cellular PVC lines from different manufacturers. We bring samples to your estimate, document the brand and profile on your written proposal, and install expansion gaps and sealed fasteners per manufacturer spec.

PVC surrounds vs what you have now
| Topic | Wood trim | Aluminum capping | PVC surround |
|---|---|---|---|
| Best for | Historic look when wood is still solid | Tight budget, sound wood underneath | Rotted sills, street-facing detail, no paint cycle |
| Rot risk | Absorbs water at end grain over time | Wood underneath can still rot hidden | Closed-cell PVC does not rot or swell |
| Paint | Repaint every few years on exposed faces | Coil color, no wood paint | Factory finish or paintable PVC profiles |
| Fit on old homes | Custom if hand-built | Formed coil, can gap on odd openings | Cut on site to your exact measurements |
How a window trim retrofit works

Measure every opening
We measure windows, doors, and garage openings at your house, not from a plan or catalog chart.

Check wood and flashing
We inspect sills and head flashing before trim goes up. Soft wood gets repaired first.

Cut PVC on site
AZEK or Restoration Millwork is cut to your widths and returns, same crew, same day.

Install and seal
Trim fastens into place, ties into siding and flashing, and joints get sealed for water shed.
