You are choosing who runs the job, not shopping a single trade. We are a licensed contractor in Maryland (MHIC #111971) — we pull the permits through the Montgomery County Department of Permitting Services, coordinate the licensed trades, and hand you a written line-item scope before demolition starts.
A whole-home renovation usually needs a building permit plus separate electrical, plumbing and mechanical permits — each with its own inspection, each on its own timeline. Pulling them is not the hard part; sequencing them so no trade is standing around waiting for an inspector is.
Your Potomac permit goes through the Montgomery County Department of Permitting Services. We pull it under our license and we hold the inspection schedule — you do not chase inspectors and you do not sign the application.
A lot of Potomac sits outside Montgomery County's public water and sewer envelope, which means well and septic. That matters more than homeowners expect: adding a bedroom — in an addition or a finished basement — can require a septic capacity review before the county will permit it, because bedroom count is how septic systems are sized. On a large-lot Potomac property this is the first thing to check, not the last.
Potomac is large-lot housing — much of it 1960s–1980s with substantial later renovation, plus newer custom construction. Many neighborhoods also carry HOA covenants requiring architectural approval for exterior changes, which runs on a separate track from the county permit.

It depends entirely on scope, so we do not publish a single number. You get a written, line-item price after a free on-site walkthrough — not a verbal ballpark over the phone.
Yes. The walkthrough and the written scope are free and yours to keep whether or not you hire us. There is no design fee and no consultation invoice.
You can hire trades directly, and for a single-trade job that is often cheaper. It stops being cheaper the moment two trades have to be sequenced around an inspection — someone has to own that schedule, and if it is not a contractor it is you. A licensed GC also carries the permit and the liability.
