Windows and doors are part of your home’s weather barrier
Every window and exterior door is a hole in the wall. How well that opening is framed, flashed, sealed and trimmed decides whether rain and drafts stay outside. When something goes wrong, the symptoms are familiar: a sash that sticks, fog between the panes, a door that drags, peeling paint under a sill, or a cold draft at the threshold.
Monarch Roofing & Construction looks at windows and doors as part of the whole exterior, alongside the siding, trim and roof around them. That matters because many window and door problems are really water-management problems at the edges of the opening.
Our work in this category ranges from evaluating a single problem window to replacing entry and patio doors and rebuilding the exterior trim around them. Each project starts with a free visit, where we look at the unit, the frame and the surrounding wall before recommending anything.
Repair first, when it makes sense
Not every issue needs a new unit. Worn weatherstripping, loose hardware or failed caulk can often be addressed on their own. When the frame, sill or threshold has deteriorated, replacement may be the better long-term option, and we explain why.

Window and door problems we see most
Most calls in this category start with one of these symptoms.
Drafts at windows and doors
Air moving past worn weatherstripping, gaps in the frame or a tired door sweep.
Fogged glass
Moisture between the panes of an insulated glass unit, a sign the seal has failed.
Sticking or hard-to-lock units
Sashes and doors that bind, drag or will not latch securely.
Leaks around openings
Stains, swelling or peeling paint below windows and beside doors.
Rotted sills and trim
Soft or crumbling wood where water has been sitting against the opening.
Sagging or out-of-square doors
Doors that no longer sit evenly in the frame or rub at the top or sides.
How we decide between repair and replacement
We look at each opening on its own. Some need a small fix, others a new unit.
Issues that can often be repaired
- Worn weatherstripping or door sweeps
- Loose or broken hardware
- Failed exterior caulk or sealant
- Small, localized trim damage
Issues that may call for replacement
- Rotted frames, sills or thresholds
- Fogged glass in many units
- Doors or sashes that will not operate safely
- Repeated leaks through the unit itself
Factors that affect the decision
The condition of the frame and the wall around it, the age and type of the unit, how many openings are affected, your budget and any other exterior work you are planning.
When further investigation is needed
Water that gets past a window or door can damage the framing below it. If we see signs of that, we explain what further investigation is needed before we set a final scope.

The window or door itself: frame material, glass, hardware and how it operates.
Flashing
Membranes and metal that direct water away from the rough opening and out over the siding.
Sealants & insulation
Caulk, low-expansion foam and backer rod that close the gaps between unit and framing.
Exterior trim
Casing, sills and brickmold that finish the opening and help shed water.

Window and door FAQs
What window and door work does Monarch do?
We inspect, repair, replace and install windows and exterior doors, including entry doors and sliding patio doors, and we repair or replace the exterior trim around them.
Are window and door estimates free?
Yes. The visit and the estimate are free, whether you have one problem window or several doors to look at.
Do you work on interior doors?
This category covers windows and exterior doors. If you have another project in mind, describe it in the form and we will tell you whether it is something we handle.
Can you match my existing windows?
We can discuss styles, colors and grille patterns that work with your other windows. Exact matches depend on what manufacturers currently offer.
Should I replace windows and siding at the same time?
It can make sense, because the openings are exposed and the flashing can be tied into the new siding. It is not required, and we can plan the work either way.
Can I send photos before the visit?
Yes. Up to five photos can be uploaded with your request. Close-ups of fogged glass, rot or damaged hardware are especially helpful.
Do you handle the trim around windows and doors?
Yes. Casing, sills and brickmold are often part of the project, and we pay attention to how water is shed at the bottom of each opening.
How soon can work start?
It depends on the scope and on product lead times. We give you a realistic picture when we confirm the estimate.
