Costs, Delays, And The Consequences Of Skipping Review

Cost is part of the decision, but it should not be the only filter.

In a historic house, average cost to replace windows in a DC rowhouse is usually above a simple standard replacement, especially when wood and custom profiles are part of the job.

Timing can also be slower than homeowners expect. If the project needs HPRB review, how long does HPRB window permit approval take will depend on the completeness of the submission and the complexity of the change.
