Eventually, time, weather, and wear take their toll on decks. Worse, your aging decks may be damaging your building envelope.
The transition where your deck attaches to the exterior wall is notoriously vulnerable to water penetration. Decks are typically fastened to buildings using a piece of lumber called a ledger board. If the flashing around the ledger board has failed, rain, snow, and ice are able to find their way into your home.
Correcting failed deck flashing is complicated. To do the job right, the deck must be removed from the building so that all components (deck, ledger board, siding, sheathing, and sliding doors) can be flashed properly. Removing, repairing, and re-attaching an existing deck is possible, but it is also expensive.
Aging decks can also develop safety and liability hazards that must be addressed. Typical “red flag” hazards include: concrete footings that are failing; support posts that are bowed or cracked; and steps and railing systems that do not meet current building codes.
Replacing aging decks using low-maintenance materials often makes more financial sense than paying for extensive repairs and future maintenance.
For even greater savings, replace your decks in conjunction with a siding replacement project. Your budget will benefit from reduced labor costs — crews will already be onsite — and it is much easier to assure that your new decks are attached and flashed as an integral part of your siding system.
I was impressed with SPS’s management, their desire to discuss what they can do and what they should not do, and their ability to get things done.
Decking is one of the key components of an integrated building envelope system.
