Winthrop Harbor questions
Good to know

How do I get a quote?
Call (224) 944-8652 for a free on-site estimate. We come out to your Winthrop Harbor home, look at the actual space, and give you a clear written price.
How soon can you start in Winthrop Harbor?
Usually within a week or two for smaller work, longer for a full build. Winthrop Harbor is on our regular route so we are not adding a trip charge to get there. Call and we will give you a real date rather than a maybe.
Do you give written estimates?
Always. Scope, materials and a firm number, in writing, before anything starts. If something turns up once we open a wall or pull trim off, you hear about it before we carry on rather than seeing it on the invoice.
Do I need to be home while you work?
No, as long as we have access. Most of our work runs with the homeowner out. We will agree how we get in and how we lock up before the first day.

Practical notes
Permits, associations and what to check in Winthrop Harbor
Interior finish carpentry generally does not need a permit. Trim, crown, baseboard, built-ins, shelving, interior doors hung in an existing opening and drywall repair are finish work. In most Lake County municipalities that does not require anyone to pull anything.
Structural changes do. Removing or altering a load-bearing wall, creating or widening an opening, and anything that changes the load path is permitted work almost everywhere. Winthrop Harbor is no exception, and it should be pulled rather than skipped — an unpermitted structural change shows up at resale and it is expensive at that point.
Egress and stairs are code items. A basement bedroom needs a legal egress window. Stair rise, run, handrail height and baluster spacing are all regulated. These come up on inspection reports even when nobody permitted the work.
Check with the village rather than with us. Requirements differ between municipalities and they change. We will tell you when a job crosses into permit territory, and we will work to whatever Winthrop Harbor requires, but the authority on Winthrop Harbor rules is Winthrop Harbor.
Associations. Association rules are less common in the older neighbourhoods here, though a few of the newer developments have them. Exterior work is the piece most likely to need a look.
What we find in Winthrop Harbor houses. The housing here spans several eras, so what we find behind the trim varies street to street. We would rather look before quoting than guess from a photograph.
