Hail cracked boards, dented aluminum or a rotted board by the back door: Martin Exteriors Roofing & Siding repairs Janesville siding by taking out the damaged boards or sections and putting new ones in, with James Hardie fiber cement first and vinyl as the other main option. We never cover damage with sealant or filler. Inspections are free and come with photos. Call (815) 624-6278; someone answers 24/7.
A Mid Century City
Census estimates for 2020 to 2024 put the median Janesville home at 1972. About 43% of homes were built between 1950 and 1979, with the 1960s and 1970s together adding about a third of the city’s houses. Roughly 14% are older than 1940, many of them on Courthouse Hill and near the Rock River downtown, and about 15% went up from 2000 on, much of that in the neighborhoods off Highway 14, Cranston Road and Milwaukee Road.
That means most Janesville siding repairs land on one of three kinds of houses, and each fails differently.
1950s to 1970s Ranches: Aluminum and Old Vinyl
Many mid century ranches on the east and north sides still wear aluminum, or vinyl that went on over aluminum in the 1980s and 1990s. Hail leaves round dents in aluminum that cannot be pushed out, and older vinyl turns brittle enough to shatter on impact in cold weather. Repairs on these houses come down to whether a match exists. When it does, we replace the damaged panels. When it does not, we can move sound panels from a hidden wall, like the back of an attached garage, to the front, or redo the damaged wall so the change ends at a corner.
Courthouse Hill and the Older Downtown Streets
Homes on Courthouse Hill and near the river are often a century old or more, tall and full of trim, with original wood lap under one or two newer layers. Repairs here usually mean rotted boards at porches and sills, split corner boards and loose casing. We cut out the rot back to sound wood, repair any soft sheathing, and fit new boards at the same exposure as the old ones. James Hardie lap is usually our choice for these runs because it looks right on an old house and will not rot again in the same spot.
Insulated Vinyl Needs the Right Replacement
Some Janesville homes have insulated vinyl, which has a foam backing fused to each panel. Swapping in a plain panel leaves a soft, hollow spot that dents easily and looks different. We match the panel type as well as the color and profile, and we tell you at the inspection if that exact panel is still available.
Hail Damage on Siding
Hail damage on siding is easy to miss from the ground. Cracked or holed vinyl, chipped fiber cement paint and dented aluminum usually show up on the side of the house that faced the storm, often with damage on the roof too. At the free inspection we photograph and measure every damaged board on every wall, look at the roof on the same visit, and tell you plainly whether a repair will match. See hail damage repair and hail damage roof repair in Janesville.
If hail keeps coming back to your walls, James Hardie fiber cement holds up to impact far better than vinyl. You can start by switching just the most exposed wall.

Janesville Siding Repair FAQ
Can you repair hail dents in aluminum siding?
A dent in aluminum cannot be pushed back out. We can move sound panels from a hidden wall to the damaged area, or replace the damaged wall in vinyl or James Hardie and end it at a corner.
My siding has a foam backing. Can you replace just a few panels?
Yes, if the same insulated panel is still made. A plain panel would leave a soft spot that dents easily, so we match the panel type, color and profile and tell you at the inspection if it is available.
Can you repair the wood siding on an older Courthouse Hill home?
Yes. We cut out rotted boards back to sound wood, repair soft sheathing, and fit new boards at the same exposure. James Hardie lap is usually our choice there.
Will you check my roof when you look at hail damaged siding?
Yes. We look at the siding and the roof on the same free visit and photograph damage on both.
