Full-Frame Window Replacement in Daly City
For homes off John Daly Boulevard and across the Westlake tracts where the damage is behind the frame, not in the glass.
When a Daly City Window Has to Come Out Completely
There is a point where patching stops being honest. Full-frame window replacement means the entire assembly leaves the building — sash, jambs, sill, exterior trim, interior casing — until we are looking at bare rough framing. Daly City Window Replacement takes this route when there is water staining on the drywall below a window, when the sill feels soft under a thumb, when the frame has racked out of square and the sash no longer meets the lock, or when decades of wind-driven rain off the Pacific have found their way past the original flashing. Houses through the Doelger-built Westlake blocks and the older streets near Mission Street frequently hide exactly this, because the original aluminum units were set with minimal flashing detail by modern standards. The advantage of going full-frame is that we get to see and repair what an insert would have hidden, then start the new opening with correct flashing, correct insulation, and a sill pan that actually drains outward.
What a Full-Frame Replacement Covers
Every item below is part of the standard scope, and each one is priced on the written quote you receive at the measure.
Complete removal to the rough opening
The sash, frame, sill and exterior trim are cut free and taken out in pieces so the surrounding stucco and interior finishes stay intact.
Inspection and photos of the exposed framing
Before anything new goes in, we photograph the opening and show you the condition of the sill plate, king studs and header so you can see what you are paying to fix.
Rot and water-damage repair
Soft sill plates, deteriorated framing and compromised sheathing are cut back to sound wood and replaced with treated or new material rated for the exposure.
Sill pan installation
A formed or flexible sill pan with end dams and a back dam goes in first, so any water that ever gets past the exterior seal drains back out instead of into the wall.
Integration with the weather-resistive barrier
Flashing tape is lapped shingle-style into the existing building paper or house wrap, sides over bottom and head over sides, which is the detail most leaks trace back to.
Setting and squaring the new unit
The window is shimmed at the jambs and sill until it is plumb, level and square, then fastened per the manufacturer's pattern so the warranty stays intact.
Perimeter insulation
The gap between frame and framing is filled with low-expansion foam rated for windows, which seals air movement without bowing the jambs the way over-expanding product does.
Exterior sealing and trim
Backer rod and a high-movement sealant close the exterior joint, and new exterior trim or stucco patching is finished to match the surrounding wall.
Interior casing and finish
New interior casing, stool and apron are installed and caulked, ready for paint, so the room does not look like a repair happened.
Cleanup and haul-away
Old frames, glass, packaging and debris leave with the crew, and floors and landscaping under each opening are protected the entire time.
How the Project Runs
- 01
The on-site measure
An estimator comes to the house, measures every opening you want addressed, and checks the surrounding wall for the signs that decide insert versus full-frame. You will be told which openings genuinely need the full tear-out and which do not. Before the visit ends you receive an itemized written quote, one line per opening, and that visit takes well under an hour for a typical home.
- 02
Order and production
Once you approve the scope, your units go into production built to the measurements taken at your house. This is the part of the timeline nobody can compress, and it usually runs three to eight weeks depending on the product line and the shapes involved. We confirm the delivery date with you as soon as the factory locks it in, and we handle the City of Daly City permit paperwork in the meantime.
- 03
Installation day
The crew arrives with floors covered and beds protected, then works opening by opening so no hole in your wall sits open longer than it has to. A typical house of eight to twelve openings runs one to two days. At the end we walk the whole job with you, operate every sash and lock in front of you, and hand over the manufacturer paperwork and the written labor warranty.
Why This Job Should Go to Us
We show you the opening before we close it
The moment the old unit is out is the only time anyone will ever see the framing. We photograph it, walk you out to look at it if you are home, and get your sign-off on any repair before the new window goes in. Nothing gets buried quietly.
Concealed rot is the only thing that moves the price, and we say so upfront
Our written number holds. The single named exception is damage that could not be seen until the old unit came off, and when we find it you get a photo, a scope and a cost before a single additional dollar is spent.
Flashing sequence done in the right order, every time
Sill pan first, jamb flashing over it, head flashing over that, all lapped into the existing weather barrier. On a coast where rain arrives sideways, that sequence is the difference between a window that lasts and a callback in the second winter.
