In a historic district, the process is rarely just "measure, order, install." The contractor should know when permits are needed, what drawings or product information may be required, and whether HPRB approved window materials list guidance affects the project.

Red Flags That Usually Show Up Early

Do not choose based on price alone. You want to know who is doing the labor, who is managing the site, how the company handles unexpected conditions, and how communication will work once the project begins.

Some red flags are obvious once you know what to listen for. If the company dodges permit questions, avoids bond documentation, sells the same product for every job, or promises easy approval before seeing the house, keep shopping.

Ask for relevant local work, not just glossy photos.

In a market where average cost to replace windows in a DC rowhouse can vary widely depending on scope, materials, and approvals, that kind of steadiness is worth paying for.
