Southeast Wisconsin
Exterior Remodeling
Exterior work is weatherproofing first and appearance second.
The exterior of a house is an assembly: cladding, drainage plane, flashing, sealant and paint, each depending on the one behind it. Replacing windows or re-siding a wall without addressing flashing produces a result that looks correct and leaks anyway.
This climate is hard on exteriors in a specific way — repeated freeze-thaw cycling, wind-driven snow against walls, and ice that forms at the eaves and works backwards under the roof edge. Material and detailing choices that work in milder climates do not always work here.
Exterior projects are also the ones most visible from the street, so scope discipline matters. Changing one elevation and not the others often reads worse than doing nothing, and that is worth discussing before the work is priced.
Window replacement is the exterior decision with the most hidden variance. A retrofit insert goes into the existing frame — faster, less disruptive to the cladding, and dependent on that frame being sound and square; a full-frame replacement strips to the opening and rebuilds the flashing — more invasive and more complete. In older housing the frame is often the reason the window failed, which pushes more jobs toward full-frame here than in newer stock. Which one your house deserves is a condition question answered window by window, not a package deal.
Where a homeowners association reviews exterior changes, its approval is part of the critical path and is treated like one — colors, materials and sometimes shade structures go through their process before work is scheduled. It is paperwork, but it is sequencing-relevant paperwork, and starting it early is free.
What we coordinate

How the project runs
Typical major phases.
- 01
Consultation and assessment
Condition of the existing envelope, and whether the problem is cosmetic or a water issue.
- 02
Design and scope
What is being replaced, what is being repaired, and where the transitions land.
- 03
Permitting where required
Structural changes, window openings and some re-cladding require permits.
- 04
Removal and repair
Remove failed material, repair substrate and address any water damage found.
- 05
Weatherproofing and cladding
Drainage plane, flashing, cladding, then sealant.
- 06
Finish and walkthrough
Paint or final coat, cleanup and inspection.
Phases describe sequence, not schedule. We do not publish durations for work that has not been scoped, and permit review times belong to the jurisdiction.
Design & preconstruction
What gets decided before we build.
- Whether visible damage is cosmetic or a symptom of a water path
- How new siding will meet existing siding, and whether a break line is better
- Materials and coatings rated for freeze-thaw cycling rather than general exterior use
- Flashing details at every window, door and roof-to-wall transition
- Whether partial work will read as a patch from the street
What moves the cost
Why two similar projects can cost very differently.
These are the variables that actually move a number. We do not publish price ranges for work that has not been scoped — a real figure comes from your project, not from an average.
- What the existing surface is hiding
- Exterior scope is decided by condition more than by preference. Siding that has cupped, split or pulled away may be cosmetic or may be telling you about water behind it. Establishing which one it is determines whether the work is a finish project or a repair project, and that is worth knowing before it is priced.
- How much preparation the substrate needs
- Preparation is most of the labour in exterior work and none of the visible result. Washing, crack repair, patching, priming and correcting previous repairs all precede any finish coat, and a finish applied over inadequate preparation fails early in this climate no matter how good the material was.
- Window and door replacement scope
- Replacing units within existing openings is one project. Changing an opening's size means structural work — a new header, framing, and re-detailing the surrounding envelope. How the new units are flashed and integrated with the weather barrier is what decides whether they leak in five years.
- Access and height
- Single-storey work reachable from ladders and two-storey work needing staging or lift equipment differ substantially in labour and setup. Landscaping, walls and tight side yards affect how equipment reaches the elevation at all.
- Matching versus deliberately changing
- Matching existing weathered siding profile or colour is achievable to a point and rarely invisible. Deciding early whether to blend a repair or to change the whole elevation deliberately avoids paying for an attempt at an impossible match.
- Specification for sun exposure
- West and south elevations take punishment that other elevations do not. Coating systems chosen for that exposure cost more per gallon and are the reason the finish is still intact several summers later.
What moves the schedule
What actually consumes the calendar.
We do not publish durations for work that has not been scoped, and permit review times belong to the jurisdiction rather than to us.
- Weather governs almost everything
- Coatings have temperature and moisture windows for application and curing, and here that is a calendar constraint rather than a weather one. Most exterior products have a minimum application temperature and need the surface to stay above it while they cure, so work pushed late into the autumn can cure badly and fail the following spring. Dew point matters as much as air temperature on cool mornings — a surface can be damp when nothing has rained.
- Coating systems cure in stages
- Multi-coat systems need cure time between coats. That interval is set by the product, not by crew size.
- Repair discovery
- Opening a wall to fix visible damage sometimes reveals more behind it. The scope is then a decision rather than an assumption, which is why the condition is investigated before the scope is fixed.
- Window and door lead times
- Units are manufactured to specific dimensions after final measurement, and that lead time typically exceeds the installation.
Before you commit
Worth understanding first.
- which exterior work is permitted
Re-siding usually is not. Changing an opening's size is structural.
What it costs
What does siding replacement cost in Southeast Wisconsin?
The Remodeling 2025 Cost vs. Value Report puts a fibre-cement siding replacement in the Milwaukee metro at $23,874 installed — 1,250 square feet of siding with trim, which works out to roughly $19 per square foot. It is a modelled 2025 cost for one defined specification, not a Monarch quote. Vinyl siding in the same report and the same market is $19,330. Roofing is the other half of exterior work and this page carries no local roofing figure: the national survey numbers below record what households said they spent across every roof material, which is not the same thing.

Questions
Answers we can give honestly.
- Can you match my existing siding?
- We can get close, and on a current profile very close. But existing siding has weathered, and a repair patch in the middle of an elevation usually stays visible — more so if the original profile is discontinued, which is common on older housing. Often the better answer is to run the new work to a natural break line.
- Do you find water damage once you open things up?
- Sometimes, particularly around windows and roof-to-wall transitions. It gets shown to you, priced and decided before the wall is closed back up.
- How long does exterior paint last here?
- Longer with proper prep and a quality coating system, shorter on south and west elevations regardless. We will not quote a lifespan we cannot stand behind.
- Retrofit windows or full-frame replacement?
- Retrofit inserts preserve the existing frame and cladding and cost less disruption; full-frame replacement rebuilds the opening and its flashing completely. The deciding factor is the condition of what exists — putting a new insert into a compromised frame is buying glass for a problem that stays. We assess per opening and tell you which your house actually needs.
- Repair the siding or replace the elevation?
- Isolated damage is usually a repair; an elevation with widespread cracking, chalking or panels that have gone brittle is a different conversation, and so is anything with soft sheathing behind it. Two honest tests. First, whether the repair will disappear or telegraph — and where it would telegraph, taking the wall to a natural break line beats a ceiling of visible patches. Second, whether the profile and colour are still available, because a panel matched to a sample will not match twenty years of fading on the wall.
How a project starts
Start with a consultation. We look at the space, talk through what you want to change and what you want to keep, and set out what the design and preconstruction stage would involve for your project.
