Home Renovations on the Main Line
Renovating a 1900s–1940s Main Line stone colonial or Tudor means working with plaster walls, deep stone foundations and decades of past updates. We keep the character that makes these homes valuable while bringing systems up to date. We handle the drawings, the local permits and the build, and price your project at a free on-site walkthrough.
Build your estimateHome renovations for Main Line homes
Main Line homes are often 1900s–1940s stone colonials, Tudors and estates with plaster walls and deep stone foundations.
- Original trim, doors and millwork protected or matched where walls change.
- Wiring and plumbing replaced with routes planned around thick plaster and stone.
What affects projects on the Main Line
- Several Main Line neighborhoods fall under historic review, which can add a design approval step before the building permit.
- Mature trees and steep lots often bring tree protection and grading review into the plan.
Additions that read as original
Main Line architecture is unforgiving — Tudor half-timbering, Colonial Revival cornices, Wissahickon schist, slate roofs, and true divided-light windows. A new wing that misses the brick coursing, the mortar color, or the roof pitch announces itself forever. We source matching stone and millwork, replicate trim profiles, and detail the transition so the addition is invisible from the street.
Permits & local rules on the Main Line
Plans are reviewed by the Lower Merion, Radnor or Tredyffrin code office, depending on your address. We file and track every permit for you.
- Step 1. Zoning review: setbacks, lot coverage and height limits set by the Main Line's local zoning rules.
- Step 2. Building permit filed with the township or borough code office serving the Main Line (Pennsylvania Uniform Construction Code), using our in-house drawings.
- Step 3. Separate electrical, plumbing and mechanical permits when systems are replaced.
- Step 4. Structural review for wall removals and new beams.
- Step 5. Rough-in inspections before walls are closed, then a final inspection.
Exact requirements depend on your property. We confirm them with the local office at your walkthrough.
