Symptom Check | Alumen Windows

Ten things you can see or feel, in about fifteen minutes

These mean replace 2 items A failure of the window itself, not of how it is being used or how it is adjusted. Nothing here can be tuned, adjusted or sealed back to health.

Fog, haze or water sitting between the panes The sealed unit has failed. Nothing applied to either face reaches the space where the problem is — the glass unit is the repair, and on most windows over fifteen years old the frame is the reason it failed. Wood you can push a screwdriver into Try the bottom corners of the sill from the outside. If the point sinks and stays, the rot is structural and it is behind what you can see.

These mean investigate 6 items Real symptoms with more than one cause. Each is worth a look, and what the look finds is what decides whether anything gets replaced — some of these are an hour of labour, some are a window.

Condensation on the inside face in winter Usually indoor humidity finding the coldest surface in the room, which a new window moves rather than removes. Worth checking your humidity before your windows. One room that runs noticeably colder than the rest of the house Could be the windows. Could equally be a duct run, an uninsulated band joist or a wall that was never filled. Measure before you attribute it. Water on the sill after wind-driven rain, but not in ordinary rain Often flashing or the sill pan rather than the window. A window replacement that does not correct the detail will leak again. Paint peeling on the interior trim under the window and nowhere else Moisture is getting into the wall at that point. Finding where matters more than replacing what is visible. A sash that no longer meets its frame — a visible gap at the meeting rail, or a lock that misses its keeper Start with the hardware, not the window. On many windows the sash adjusts back into its frame and the seals re-engage — an hour, and a part at most. On others the frame itself has moved out of square, and an adjustment holds for a season before the frame takes it back. Which one you have is what decides this, and it is worth finding out before anybody prices a window. Daylight visible around a closed sash Stand inside with the lights off on a bright day. If you can see a line of light, air and water are using the same route — so this one does need dealing with. Adjusting the hardware closes some of them; where it does not, replacement is a real possibility. Have somebody try the adjustment first.

These are usually not the windows 2 items Here so you can stop wondering about them. If these are your main complaints, replacing windows is an expensive way to be disappointed.

Street or neighbour noise you notice most in one room Glass is rarely the weak point. The wall assembly, an exterior door, a vent or a chimney flue usually is. Acoustic glass helps at the margin and costs real money. A high energy bill with none of the symptoms above Windows are typically a small share of a whole-house loss. Air sealing an attic hatch is usually the cheaper first move, and you can test that claim before you spend.

Ten observable items is a triage, not a survey. Nothing here inspects the wall, the flashing or the header — a failure item tells you the window has gone, not what else has. It is not an energy assessment: if the bill is the complaint, a blower-door test answers it and this page does not. And there is no price on this page.
