What is different about deck construction in Connecticut

Older housing stock means knob-and-tube, asbestos and undersized services surface constantly; budget for discovery work that newer-stock states rarely hit.

Owner-builder: Homeowners may permit work on a single-family home they occupy. Deck Construction is one of the scopes a homeowner can more realistically permit themselves.
