Read before you cut
Original framing that is not plumb, layered additions and finishes worth preserving get an approach that solves rather than fights.

Chester County / Since 2006
Older Chester County housing stock, where the pleasure and the difficulty are the same thing: the house already has a strong point of view.
Working in West Chester
West Chester and the surrounding townships hold a lot of older housing, and older houses rarely arrive as blank canvases. Rooms are smaller, framing has moved, and previous additions carry their own logic.
Delpa's approach is to read what is there first — solving what appears when walls open, and building the next chapter so it belongs. That has been the working method across Delaware, Pennsylvania and Maryland since 2006.
The housing stock
Typical work here involves kitchens and baths in properties that have been renovated before, exterior projects on houses where the materials have aged out, and additions that have to sit convincingly against an existing façade.
Delpa also covers nearby Landenberg and the southern Chester County townships, which sit close to the Delaware line and well within regular working distance of the New Castle office.

Roofing, siding, windows and trim specified together so the flashing and transition details are owned by one team.
Roofline, floor level and material transitions resolved before framing so new work reads as original.

Yes, and it is a large share of the work. Older houses come with their own logic — framing that has moved, additions from several eras, finishes worth keeping. The approach is to understand what is there before deciding what changes.
Delpa files the permits its work requires with the borough or township office covering your address and manages the inspection schedule. That process is explained at the consultation so you know what is involved before work starts.
