Known work
List the openings and the product choices, removal, installation, disposal and agreed finishing. Identify painting or staining separately so a finished installation does not leave an unexpected finishing task.
MRBCC / Mundelein, Illinois
Mundelein window replacement, from the opening to the finishing details.
A new window is only part of the work. The frame it fits into, the surfaces around it and the approval process all affect the result. MRBCC helps Mundelein homeowners put those decisions in order before committing to an installation.
Discuss my Mundelein windowsFirst decision / local review
Keeping the size does not remove the permit step.
Mundelein's July 2026 Homeowner Project Guide requires a permit for replacement windows. Where opening dimensions change, it also calls for construction details. Start with the village's current guidance rather than an older handout or another town's exemption.
Read the village guide, page 21
Second decision / what stays
Preserve the details you value, not a frame that needs attention.
The Heritage Museum is a recognizable Mundelein landmark. Its photograph is community context, not a model for every home's windows or a claim of work by MRBCC.
At your home, identify interior casing, stools, exterior trim and finishes you want to keep. An insert replacement may retain an existing frame when conditions allow; a full-frame approach exposes more of the surrounding opening. Neither should be selected on appearance alone.
Ask how the proposed method affects visible glass, trim depth and the connection to the wall. Damaged material should be assessed before it is covered by a new finish.
Third decision / the written scope
Agree on the edges of the job.
Work that needs investigation
Describe soft trim, staining or recurring moisture without assuming the window is the only cause. Ask how exposed conditions will be documented and how you will approve additional repairs.
Finish with a usable record of the replacement.
Keep the signed scope, product labels and any written warranty information together. Walk through operation, locking and the agreed interior and exterior finishes. Confirm that required inspections have been addressed rather than treating the crew's last day as automatic permit closeout.
For your first message, tell us how many windows you are considering, what has changed in their condition and whether preserving existing trim matters to you.

Before you decide
Mundelein window questions
Does a same-size window replacement need a Mundelein permit?
The village Homeowner Project Guide, updated July 14, 2026, lists replacement windows as requiring a building permit. Do not assume keeping the opening size makes the work exempt. Confirm the address and proposed work with the village before proceeding.
What should I decide before ordering my Mundelein windows?
Resolve the installation method, final measurements, product specifications and finishing scope first. If the opening will change, include that in the review. An approximate window count is enough to start a conversation, but it is not an order specification.
Will replacement mean losing my existing interior wood trim?
Not necessarily. Whether trim can remain depends on its condition and how the new unit will be installed. Tell MRBCC which details you want to preserve and ask for retained, replaced and refinished surfaces to be identified in the proposal.
How do we handle damage discovered after an old window is removed?
Ask for a written process before work starts: document the condition, explain the proposed repair and agree on any change in cost or schedule. Hidden deterioration cannot be priced reliably from a window count alone.
Window replacement / Mundelein
Tell us about the windows you want to replace.
Start with the rooms, the approximate number of windows and what is not working for you. MRBCC will get back to you to discuss the project, available options and next steps.
A request is not a booked appointment or a final price. Product selection and installation timing are confirmed after discussing your home.
