Seal bottom of vinyl siding.

There are 3 main types of siding. Grass and mulch along the foundation provides habitat for mice. 6 siding transitions by foundation often siding is not secured all along the bottom near the foundation. Simply apply this inexpensive filler into the cracks to seal.

Although vinyl is impervious to water when installed as directed by the manufacturer vinyl siding as a whole is not completely watertight. Mice can climb under the siding and enter the home through an existing construction gap. Each one has its own vulnerabilities. Vinyl siding installs in pieces so gaps and overlaps.

The bottom row of siding should sit flush against some form of backing. Caulking is not usually the solution to a mouse problem. Put on your gloves bring a rag for cleaning spills then visit the cracks and gaps you spotted along your siding. On the other hand what may help is sealing you sheathing plywood osb to the foundation.

In addition again talking from the vinyl experience the siding is not really the air barrier vinyl often has a drain hole in the bottoms of each layer to allow moisture to escape so sealing it would do little to nothing for your air infiltration. Vinyl siding starter strips snap a level chalk line for the first starter strip at the base of the wall no less than 8 inches above ground level after determining the lowest corner of the house. Step 6 seal small cracks and gaps in your siding under 1 4 inch wide using an acrylic latex caulk. Vinyl siding does not fit tight inside j channels or corner posts you don t caulk them shut and there are voids behind the lap siding too.

This chalk line should be level and a consistent distance from the eaves or the top and bottom of the windows. Bottom line is you don t caulk places where water needs to weep out. This is where the new siding will begin. If it s 3 4 or more i d concider removing the bottom row of siding and starter strip and install a piece of 1 x 6 vinyl lumber then a piece of z moulding then replace the starter strip with j moulding reinstall the siding.
