What happens on window installation day in an Austin house
Window day looks chaotic from the kitchen table: a truck in the driveway, plastic over the furniture, a drop cloth on the porch and a crew that seems to be going in six directions. It follows a fixed order, though, and knowing the order makes it easier to spot what is going wrong. The questions below are the ones that come up most often from homeowners in Austin, TX in the hour before the crew starts.
How long does a replacement job take in a typical house?
A crew of two usually does a standard double hung or single hung in a single sitting, from pulling the old sash to a finished interior. A full-frame replacement takes longer because the opening has to be opened up, flashed and trimmed again. A whole house is normally scheduled across more than one day, and a crew that promises everything before lunch is either working from a very small house or skipping steps.
Weather can move the date. Austin storms arrive with little warning in spring, and installers do not leave an opening bare when rain is coming. A crew that stages the work so only a few openings are open at once can close one up quickly if the sky changes.
What should be moved before the crew arrives?
Everything within an arm's length of each window and a clear path from the front door to the opening. Curtains and blinds come down, furniture moves back a few feet and pictures come off the walls nearby, because pulling a nailed frame sends vibration through plaster. Pets are best kept in a room away from the work, since open openings and dropped tools are bad for a dog or a cat.
- Take down blinds, rods and any shelf resting on the sill.
- Clear the floor under every window being replaced.
- Photograph each window from inside before the work starts, so the original reveals and trim lines are on record.
- Make sure the crew can reach the outside of each opening, including any beds of plants or a fence line close to the wall.
What happens in what order?
The crew starts outside or inside depending on the product. A typical sequence for a pocket insert goes like this: the stops and sashes come out, the old sill is checked, the opening is measured against the order sheet, and the new unit is dry-fitted before anything is fastened. A full-frame job first removes trim, then the frame, then checks the rough opening for rot and square.
After that comes the layer that nobody sees afterward. A sill pan or sill flashing goes in first, side flashing next, and head flashing last, each lapped over the one below it. The unit goes into the opening, gets shimmed level and plumb, and is fastened where the manufacturer permits. Insulation fills the gap, sealant goes on the outside perimeter, and trim goes back on the inside. A last check follows: the sash opens, closes, locks and sits evenly in its frame.
Is dust and noise a problem?
Yes, to a degree. Cutting out an old wood frame or breaking the plaster at the edge makes dust, and prying a nailed casing makes noise. A good crew lays a drop cloth under each opening, bags debris as it comes out and vacuums before moving on. In a house built before the late 1970s, particularly the older bungalows around Hyde Park and Clarksville, old paint may contain lead, and the crew should be working with that in mind: wet methods, no dry sanding, and cleanup that uses a vacuum with a fine filter instead of a broom.
Does the job need a permit?
That depends on the work and on the city's current rules. Replacing a window in the same size opening is often treated differently from enlarging or moving one, which changes the structure and can require a header. The City of Austin publishes its own requirements for residential permits, and the answer for a given house should be confirmed with the city's development services office, not assumed. A homeowner who is unsure can ask the installer to state in writing who is responsible for the permit question.
Homes in a historic district or an association with design rules may have limits on frame material, colour or the look of the divided lites, so the order should be checked against those rules before it is placed.
What does a bad install look like on the first day?
The signs are visible without any tools. Sashes that drag, lock side latches that do not quite meet the keeper, uneven gaps between the sash and the frame, and sealant lines with holes or smears are all immediate. A window that rocks in the opening was not shimmed. A frame that bows inward at a fastener was tightened too hard. Daylight at the edge of a closed sash means a gap in the weatherstrip or the foam.
The things that cannot be seen are the flashing and the fastening behind the trim. For those, ask the crew to photograph the sill pan and the tape before the unit goes in. A crew that does this routinely does not mind being asked.
Who cleans up, and what should be left behind?
The crew removes the old windows, packaging, offcuts and used sealant tubes. The homeowner keeps the spare parts that come in the box, such as extra screens, keys or crank handles, and the paperwork, including the glass label figures and the warranty details. Old windows have little value as reusable units, though a few architectural salvage yards in the Austin area will take solid wood sashes from older houses, and it is worth asking the crew to set the best of them aside rather than throw them in the truck.
Should the windows be cleaned right away?
The glass will carry a protective film or residue in places, and the frame may show traces of the adhesive from labels. Wait until the sealant has cured before wiping the perimeter, since pressing on a fresh bead can pull it away from the frame. Clean the glass with a mild soap and water and a soft cloth. Harsh solvents, razor blades on coated glass and abrasive pads can scratch the low e coating or mar the finish on a vinyl or fiberglass window frame.
When should the windows be looked at again?
Twice. Once in the first week, to catch anything that slipped through on the day: a sash that has started to stick as the foam cured, a bead of sealant that has sagged, a piece of trim that has come loose. And again after the first hot, dry stretch, when the clay soils around Austin pull on slab foundations and the openings may shift slightly. If a sash starts to bind then, it is the opening that has moved, and a quick adjustment of the shims and the hardware often settles it.
What is the one thing worth doing before the crew leaves?
Walk every window with the crew lead, open and close each sash, and look along the edges at eye level. Anything that needs fixing is fixed in minutes while the tools are still on the porch, and it takes a day to get them back.
