How to Preserve Original Character During a DC Window Upgrade

Upgrading windows in Washington DC is never just a product choice. On a historic rowhouse, a bad decision can flatten the whole front elevation, even if the new units are technically better insulated.

That is why the first question should not be "what is the most efficient window?" It should be "what does this house need to keep looking like itself?"

Small Details Matter More Than Most People Expect

Good installation is about fit as much as product. A well-made window can still look wrong if the casing is altered, the reveal is inconsistent, or the sill profile is changed too aggressively.

The same goes for rear work, even if the rules are looser. A rear addition or basement opening still affects the way the home reads as a whole, and basement egress window requirements Washington DC can add another layer of planning if code upgrades are involved.
