Siding & Exterior Finishes

Most houses here wear siding, so most exterior work ends as siding work: elevations replaced, openings reframed for new windows and doors, additions tied into existing walls, storm and impact damage repaired. It is less a separate trade than the skin every other exterior scope has to close correctly, and the quality of a remodel is often visible first at the line where new siding meets old.

Southeast Wisconsin houses carry a mix: vinyl on most of the post-war and subdivision stock, aluminium still in place on plenty of 1950s and 1960s homes, cedar and wood lap on older and higher-end houses, brick on a great many Milwaukee bungalows and often brick below with siding in the gables, and fibre-cement or engineered wood where an elevation has already been replaced once. Each fails differently and each is repaired differently, so the first question on any exterior is what is actually on the wall — and what is behind it.

The thing that ruins walls in this climate is water management, not the siding face. Wind-driven rain, snow sitting against a wall, ice damming at the eaves and freeze-thaw cycling all attack the layers nobody sees: the weather-resistive barrier, the flashing over window and door heads, and the kickout flashing where a roof edge meets a wall. That last detail is missing or wrong on a remarkable number of houses, and it is the single most common cause of rot found behind otherwise sound-looking siding. Re-siding is when those details get corrected, which is most of its value.

Partial repair is harder than it sounds, and for an unglamorous reason: siding fades and profiles get discontinued. A vinyl panel matched to a twenty-year-old elevation will match the sample and not the wall, because the wall has had twenty years of sun. The honest playbook is the same as for any patch — finish to a break the eye accepts, which outside means an inside corner, a trim line or a whole elevation, rather than feathering new panels into the middle of a visible face and hoping. Where a true match is not available we say so before the work, not after.

Re-siding is also the one moment when adding continuous exterior insulation is cheap, because the walls are already open to the sheathing. In a heating climate that is a genuine opportunity and it is routinely missed — the crew is there, the siding is off, and the incremental cost of insulating is a fraction of doing it as its own project later. Whether it is worth it depends on what the walls already have and on how the window and door details would need to change to accommodate the added thickness, which is a design decision rather than an upsell.
