Inset siding nails

Are your siding nails inset within the siding boards themselves, like those pictured here?  If so, it’s either because (a) the nails were overdriven or more likely (b) the siding is swelling and expanding with moisture.  Inset nails need to be sealed to prevent moisture intrusion which can lead to deterioration.  For siding discovered at this home inspection in Freeland on Whidbey Island, substantially swelled/deteriorated siding needed to be replaced.

Cement fiber siding

Cement fiber siding products are an excellent, high quality and low maintenance material.  In fact, I’m a big fan of these products; if I build a home again myself, I intend to install cement-fiber siding.  Broken, cracked or otherwise mechanically damaged cement-fiber siding boards should be replaced by a qualified contractor.  If you have a lot of broken siding boards, replacement can be expensive.  If you don’t have the budget to replace broken boards in the near future, I recommend at least caulking cracks and securing broken pieces to prevent water damage while you budget for replacement.  This photograph was taken at a recent home inspection in La Conner.

VIDEO: Oak Harbor Home Inspection Discovers ROT at Deck/Siding Interface

At a recent Oak Harbor home inspection, I discovered deterioration, rot and water damage at the interface between the deck and exterior siding. This interface really should be flashed with a metal flashing detail to prevent water intrusion which can lead to WDO (wood destroying insect) activity and water damage. When deterioration is presenting at this interface, there’s always the possibility of underlying structural damage not visible without invasive inspection. A qualified contractor should further evaluate, invasively, to determine the extent of deterioration and make necessary repairs.

VIDEO: Huge Open Seams in Siding!

Failed caulking details and huge vulnerable seams between siding abutments at the exterior of a home in Friday Harbor in the San Juan Islands were discovered at a recent home inspection. It’s very important to protect open seams at the building’s exterior from water intrusion which can, and will, lead to water/insect damage in short time. Caulking abutments is advised, or installing a metal flashing detail behind open seams does the trick too.

VIDEO: Deteriorated Composite Siding Discovered!

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.

LP InnerSeal composite siding

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).

Video: DAMAGED Cement-Fiber Lap Siding Boards!

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 joist hangers on old siding

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.

Video: FAILED Caulking at Siding Abutments!

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.
