If you have composite siding, installed in 1996 or prior, that has the signature “LP” knot pictured here, you likely have LP InnerSeal composite siding, a product that was subject to class-action lawsuit for premature failure and elevated maintenance requirements. Well and annually maintained (e.g., painted and caulked according to LP’s requirements), this product will deliver years of serviceable life, but it does require elevated maintenance for sure. I’ve inspected many homes with this product in excellent condition. I’ve inspected many in poor condition. Deterioration typically happens first at the bottom lap edge of lap siding boards and panels. Water wicks into the exposed bottom lap edge causing the composite siding to swell, edge-check (crack), obviously deteriorate, and sometimes it presents fungal growth. Also pictured here is clearly deteriorated LP InnerSeal composite siding. With deterioration, there’s always the possibility of underlying damage not visible without invasive inspection. Therefore, for this recent home inspection in Oak Harbor on Whidbey Island, I recommend further evaluation by a qualified contractor, one familiar with LP InnerSeal siding products. Other areas that commonly deteriorate are at siding/siding and siding/trim abutments and where caulking has failed (e.g., around exterior penetrations like windows and doors).
Damaged cement-fiber lap siding boards were discovered at a recent home inspection on Orcas Island in the San Juan Islands. A qualified contractor would recommend repair and replacement of damaged siding boards, which can be surprisingly expensive. It’s always important to get bids for repair prior to closing as costs may be surprising and it’s important to fully understand the home’s issues, and costs to remedy, prior to closing so you’re fully informed.
New deck joists hangers were installed directly onto older wood siding, without the installation of a proper bolted 2x deck ledger at a recent home inspection in Anacortes. The most common point of failure for deck systems is at the interface between the deck and home. For this reason, a bolted deck ledger is advised and the deck joist hangers are attached to this instead of thin siding. I recommended further evaluation and repair by a qualified contractor who will likely install a new deck ledger underneath the existing deck joists to the whole deck doesn’t need to be dismantled.
Typical failed caulking details were noted at a recent home inspection in Anacortes on Fidalgo Island. These are so commonly called out at my home inspections, that I have a “script” detailing what the issue is and how to fix it. This video shows failed caulking at siding abutments and talks a little about installing a back-flashing detail behind the abutments to eliminate the need to caulk and monitor into the future. In fact, homes built today with cement-fiber siding typically back-flash siding abutments.
LP InnerSeal composite siding is a product that was subject to class action lawsuit for elevated maintenance requirements and premature failure. The siding on this particular house was in EXCELLENT condition, documented at a recent home inspection on San Juan Island. Well maintained, painted and caulked, this product will deliver years of serviceable life. This particular inspection was conducted in 2017, and the siding was installed in 1993, in excellent condition. So, just because you may have a home with LP InnerSeal siding, doesn’t mean it’s in poor condition. Keep it maintained and you’ll be fine, but pay attention to painting and caulking! Continue reading
Steel siding includes a variety of building cladding made from steel, which is an alloy of iron that contains a small amount of carbon. Long preferred as a siding material for industrial and commercial buildings because of its durability and lack of required maintenance, steel’s plain appearance has historically made it an unpopular choice for residential siding. However, newer steel siding is gaining popularity for residential use because it addresses cosmetic considerations. InterNACHI inspectors should familiarize themselves with it and can pass along maintenance tips to their clients who are considering new builds or renovations. Continue reading
Completely deteriorated composite exterior siding was discovered adjacent the window at the upper level of a home at a recent home inspection on San Juan Island (Friday Harbor). Keeping exterior elements properly sealed (painted and caulked) is critical to helping prevent siding/trim damage and water intrusion. In this case, repair and replacement of deteriorated siding was warranted, recognizing the possibility of underlying damage not visible without invasive inspection.
