How Water Gets Past a Window
Most leaks are not through the glass. Water gets in where the frame meets the wall: at the corners of the sill, behind trim with failed caulk, or through a door threshold that slopes the wrong way. Over time it soaks sheathing, studs and drywall, often showing up as stains or bubbling paint below the window long after the damage started.
Our Installation Sequence
- Prepare the opening. On full-frame jobs we inspect and repair the rough opening and replace any damaged wood.
- Sill protection. A sloped or formed sill pan catches water and directs it outside.
- Flashing in shingle order. Sill first, then sides, then head, so each layer overlaps the one below like roof shingles.
- Set, level and anchor the unit per manufacturer instructions.
- Insulate and seal the gap with low-expansion foam and exterior sealant, leaving weep paths open.
- Trim and inspect, then test operation and locks.
Doors Need Extra Attention
Exterior doors sit at floor level where splash-back and runoff collect. We install a sill pan under every exterior door we replace, make sure the threshold slopes out, and adjust the sweep so it seals without dragging. On patio doors, we check that the patio or deck surface is not directing water toward the opening.
Ready for Storm Season
Proper anchoring and sealing help openings hold up to strong wind. If you are weighing tougher glass too, read our comparison of impact and standard windows. For roof and exterior work beyond windows, see our Brandon roofing services.
Common Questions
What types of windows and doors do you install in Brandon?
Double-hung, casement, sliding, picture, bay and bow windows, plus entry doors, storm doors and sliding or French patio doors, from brands such as Pella.
How long does installation take?
Most homes take a few days once custom units arrive; a single door is usually a one-day job. Repairs to rotted openings can add time.
My current windows leak. Is it the window or the installation?
It can be either. Fogged or cracked glass points to the unit, while stains at the corners or below the sill usually point to installation or flashing. We inspect to find the source before recommending a fix.
Do you offer energy-efficient options?
Yes. Low-E glass, insulating gas fills and well-sealed frames are standard choices, and we review the energy ratings for each product with you.
