Working in Castle Shannon

What Castle Shannon houses actually need

The borough’s own description is the useful one: homes are on all the hillsides. Long narrow parcels on slopes decide access, staging and where water goes long before anyone picks a shingle.

  • All three light rail lines converge here, which is why the borough built out early and then again after the war — two housing stocks, roughly forty years apart, on the same streets.

The housing stock

Two distinct growth spikes — one between 1880 and 1920, another through the 1950s.

Permits in Castle Shannon

Permits for work here are issued by Castle Shannon Borough. The borough uses Building Inspection Underwriters as its inspection firm alongside borough staff.

We pull the permit and meet the inspector. We deliberately do not publish permit fees — municipalities revise them, sometimes annually — so we confirm the current figure with the office while we are writing your estimate rather than quoting you something out of date.

Getting there

A short run from the shop from our shop on 4607 Library Rd in Bethel Park.

  • The crew did an outstanding job — extremely clean, highly professional, and impressively efficient. Their communication throughout the project was excellent, keeping me informed at every step. They had repaired my roof last year, and when a severe storm came through, I knew exactly who to call. The owner was on site to check the workmanship, which gave me even more confidence in the quality of the project. The roof looks fantastic, and the entire process was smooth and well-executed. I couldn’t be happier with the results.

  • Answered my request for an estimate to repair storm damage to my home with inspection, and estimate in two days. When I confirmed and signed work started next day. Work was completed within two days and I added other items as the quality and attention to detail was first rate. I recommend.
