FAQs

How much does BCTWR restoration process cost vs. replacement?

Our Moisture Removal Process can save at least 50% compared to the cost of glass replacement. In many cases much more than 50%

Do you reseal the window?

We do not reseal the window. The BCTWR process involves one of our qualified technicians drilling a small hole in the corners of the window pane. The holes are then covered with our Micro-vents which allow the window to completely dry itself out, while preventing any additional moisture, bugs or debris from getting inside. So the window is not resealed, but permanently vented, which keeps the window moisture-free.

When is the best time have my window(s) serviced?

Once a window has failed, it will never get better on its own. You want to have your windows serviced as early as possible to avoid long term exposure of water on the glass, which causes damage (staining). The earlier the window is treated once it's failed, the higher the probability it can be restored to its original clarity. Severe staining cannot be removed leaving no real option other than replacement.

How long does the moisture removal process take to get the windows completely dry?

It takes roughly an hour for our service technicians to treat a failed window. We will completely dry out your window before we leave. Once serviced, it is normal to see some moisture for up to twelve weeks while the window dries out. Each day as the window heats up, a small amount of moisture will evaporate and be expelled out the installed Micro-vents, over time, completely drying the window. It often takes less than the full twelve weeks for most windows to dry.

Do the holes drilled into the window obstruct or affect the viewing area?

The holes are very small (about 1/8 in. or 3mm) in diameter and are usually drilled in the corners to be discreet and out of the main view-space. Each hole is covered with a transparent Micro-vent that is about half the size of a dime. Once installed, the vents are barely noticeable and in many cases are obscured by blinds or other window coverings. We like to think that windows are meant to be looked out of. We don’t look at windows. If you are looking for the valves, you can see them. But they don’t stand out. We have completed thousands of defogging jobs successfully without complaints of the valves being unsightly.

How does the moisture removal process affect the insulating quality of a window?

The key to preserving the insulating quality of a dual-pane window is maintaining a dry buffer of air between the panes. When there is moisture inside, the air is saturated and conducts hot and cold. BCTWR recreates the dry airspace and restores the window's insulating qualities back to within normal range.

Does the moisture removal system also remove stains on the inside of the panes?

Heavier set stains do not come out and we recommend replacement of the window glass. A technician needs to visually inspect the window to determine the degree to which the window can be restored and whether it would be a good candidate for our restoration process.

Does the glass have to be taken out during the installation?

No. The service is usually done with the window in place.

Can you repair patio sliders or French doors?

Patio sliders and French doors are made using tempered (safety) glass which is designed to shatter into small fragments if broken. Unfortunately, we are unable to drill into tempered glass without shattering it, so we recommend that tempered doors or windows that have failed be replaced.

Do you repair windows in high-rise buildings?

Yes. Windows that are above the 4th floor of any building are serviced from the inside of the building. If we can touch the outside pane from opening a surrounding window we can drill to the outside. If we cannot drill the outside pane then we drill the outside pane.

Should I have all of the windows in my home pre-treated before I see moisture in them?

In some cases we recommend having all your windows treated with our preventative process before the failure occurs. If many of your windows are failed in a particular area, we believe the rest are already failed or are due to fail soon. Our preventative process is 50% the cost of the restoration (moisture removal) service and carries the same 10 year warranty against moisture. Have all of your sun-exposed windows pre-treated and avoid the higher cost and inconvenience of dealing with them individually as they fail.

I've heard that windows are filled with gas. Is this important?

Very few windows are being manufactured with their airspace filled with Argon or a similar inert gas. It's true that this gas can make a small difference in the window's ability to insulate but there are much better products that cost much less.

There was a failed seal on the window, so how does drilling a hole in the window remedy the failed seal?

The seal failure is somewhere along the bottom edge of the glass. We know the failure is on the bottom of the window because if the failure were on the sides or top, the unit would fill up like an aquarium. When the sun hits the unit, the airspace between the panes of glass expands, drawing moisture in the seal failure. If I drill a 1/8" (3mm) hole 3/4" of an inch off the bottom of the window and install a valve after drying the window, it will stay dry. When the sun hits the window and the airspace wants to expand, the air can escape thru the valve (The path of least resistance). I advertise an 85% success rate. The 15% of the windows that do not work, have seal failures greater than the valves can handle. I have an A+ rating for ten years for a reason. The windows we defog have a lifetime warranty. I guarantee they stay dry and will replace the units for the difference in price if a customer is dissatisfied for ANY reason. Let’s take a very real example of a defog that does not work or a customer in a year decides they want a new window for any reason; Customer pays $66 for a defog and is quoted $150 for replacement at the time the quote is written (we write both defog and replacement prices in every instance). The customer has a $51 lifetime credit (BCTWR keeps $15 valve cost (outlined on the invoice)). Customer pays difference of $99 to replace the unit if dissatisfied for any reason - no questions asked.
