Methodology

The Protected Garage exists because finding a great PPF, coating, tint, or detail shop in Northern Virginia currently means reading forum threads and hoping. We think you deserve better than hope, so here is exactly how this site works — including how we make money, because that’s the part most directories hide.

Who runs this

The Protected Garage is independently owned and based in Northern Virginia. It is written by an enthusiast who researches and buys these services as a customer in this market — not by a marketing agency, and not by the shops themselves.

How shops get included in our guides

A shop appears in our editorial guides (like “Best PPF Installers in Northern Virginia”) only if it meets all of the following:

  1. Established operation — at least 3 years installing in the Northern Virginia / DC metro area under the current ownership or lead installer.
  2. Verified reputation — a consistent pattern of positive customer feedback across review platforms and enthusiast communities, with attention to how the shop handles negative reviews, not just the average score.
  3. Manufacturer certification — for PPF and coating shops, current listing on the relevant manufacturer’s official installer locator where the brand requires certification.
  4. Direct verification — we confirm basics directly: the shop is operating, services and films offered are as advertised, and pricing ranges we publish reflect real quotes or shop-confirmed figures.
  5. No unresolved patterns of harm — no consistent unresolved complaints involving damage, warranty refusal, or bait-and-switch pricing.

We do not include every shop that qualifies — guides feature the shops we believe are the strongest choices in each category. Exclusion is not an accusation; inclusion is an endorsement of fit for the use case described.

What paid placement buys — and what it can’t

Some shops pay us. Here’s exactly what that means:

  • Featured profiles (paid) get expanded presentation: photo galleries, detailed service and film information, and direct quote routing. They are labeled.
  • Sponsored placements (paid) are clearly marked “Sponsored” wherever they appear.
  • Editorial rankings cannot be bought. A shop’s position in, or presence on, a “best of” guide is never for sale. Paying us does not add a shop to a guide; not paying us does not remove one. If we ever feature a shop we have a paid relationship with in an editorial guide, that relationship is disclosed on the page.

If you ever believe a placement is misleadingly labeled, email us — that’s a defect we want to know about.

Where our pricing data comes from

Published price ranges come from real quotes collected from area shops, shop-confirmed figures, or both. Prices are presented as ranges because your vehicle, condition, and coverage choices move the number. We date-stamp pricing content and refresh it periodically; always confirm current pricing with the shop.

Corrections and removal requests

Shops: if anything on your profile or in a guide is inaccurate, email [email protected] with the correction and supporting detail. We respond within 2 business days and correct verified errors promptly. We do not remove truthful, fairly-presented information, but we will always fix mistakes.

Readers: if your experience with a listed shop sharply contradicts what we’ve published, we want to know that too.

What we are not

We are not a lead-broker that auctions your contact info to whoever pays most. When you use our Get Matched form, we route you to shops we’d recommend for your situation — typically two or three — and we tell you who they are. We are not affiliated with any film, coating, or tint manufacturer.
