Most remodel failures are water failures
Envelope-first thinking
Flashing, drainage, housewrap, air-sealing — the details a roofer obsesses over are exactly the details that decide whether a kitchen, basement, or addition still looks new in ten years. We detail the envelope before the finishes go on.
One accountable team
When the same contractor owns the roof tie-in, the framing, and the drywall, there's no gap for finger-pointing. One point of contact, one schedule, one warranty conversation — from first walk to final walkthrough.

2 minutes · FreeOn-site walk & written scope
We walk the property, measure, and turn your configuration into a written, itemized scope of work with real numbers — typical ranges confirmed on-site, nothing vague, nothing verbal. $0-down financing from 12 to 180 months (on approved credit) is quoted alongside.

Roof, kitchen, basement, deck, addition — pick every area your home needs, choose Good/Better/Best, and watch the itemized ballpark update as you go. No appointment, no pressure. When you're ready, we confirm it on-site in writing.
Open the Project Builder →What you are actually buying from a general contractor
Not labor. You can buy labor anywhere. What you are buying is that one entity owns the critical path and the consequences. That means the trades show up in the right order, the inspections are scheduled so nothing sits waiting, the long-lead materials are ordered before the room is ready for them rather than after, and when something is discovered behind a wall, one company prices it, documents it and gets your approval in writing before proceeding.
It also means there is one answer to the question of who is responsible. When a homeowner hires trades separately and the finished shower leaks, the tile setter says the plumber's pan was wrong and the plumber says the tile setter cut the membrane. Under one contract, that argument happens inside our company instead of inside your house.

We came to general contracting from roofing and siding rather than from cabinetry, and that shapes what we catch. A wet basement is usually a gutter and grading problem. Peeling paint on a ceiling is usually a flashing problem. A window that will not close is often a structural settlement problem. A deck that feels bouncy is a ledger and band joist problem. Those are envelope questions, and a remodeler who subcontracts the envelope will find them, stop, and hand you a phone number. See roofing, siding, aluminum siding, windows and gutters, soffit and fascia, or start with the full remodeling index.
Permits and approvals across a genuinely complicated region
The DMV has more overlapping permitting authorities per square mile than almost anywhere in the country, and the differences are not cosmetic. Montgomery County's Department of Permitting Services covers Bethesda, Potomac, Silver Spring and Olney, but the City of Rockville and the City of Gaithersburg issue their own. Howard County's Department of Inspections, Licenses and Permits covers Columbia and Ellicott City, and Columbia adds mandatory village architectural review on top. Annapolis is a city permit inside city limits and Anne Arundel County outside, with Chesapeake Bay Critical Area rules layered over anything near tidal water. Bowie files through Prince George's County DPIE.
We do not publish fee schedules or review timelines, because those are set by the jurisdictions and they change. What we do is tell you, for your specific address, which agency reviews your project, what triggers a permit for your specific scope, what design or covenant review has to clear first, and what inspection sequence to expect.
Straight answers
Are you licensed for general contracting in Maryland?
Yes. We hold Maryland MHIC license #111971, and every crew is fully insured. Both license numbers appear on every contract we sign.
Do you handle HVAC, electrical, and plumbing?
Those systems require licensed trade professionals in Maryland, so they are performed by licensed trade partners — coordinated by us under one written scope, one schedule, and one point of contact, so you never have to referee between trades.
How does pricing work on a general contracting project?
You can get a live ballpark in minutes with the Project Builder — pick your scopes, choose Good/Better/Best, and watch the range update. Then we walk the property and put a written, itemized scope in your hands. All prices are typical ranges confirmed on-site, and $0-down financing from 12 to 180 months is available on approved credit.
Do you pull the permits?
Yes. We prepare the documents, pull the required county permits, and schedule every inspection for the scopes we run — you never touch the paperwork.
Why hire a roofing company as a general contractor?
Because most remodel failures are water failures. A contractor who started in roofing thinks envelope-first: flashing, drainage, and air-sealing get detailed correctly before the finishes go on. We've run exterior projects across Maryland since 2005 — the same accountable team now takes projects from the roofline to the basement slab.
One contractor. One scope. One number to call.
Anywhere in Maryland. Start with a live ballpark, end with a written scope.
