Water capture ideas ?

You will need to get the windows repaired or replaced at some point. Water and electronics is a bad combination. The other issue is mold growth. If the windows leak, water is getting into the wall below the windows. This can be a serious health issue. In the meantime, check to see if the caulking needs to be redone.

sounds like a caulking issue - whoever you rent the office from should be able to fix this issue - not much you can do to keep water from pooling but to line windows with towels or rags but it can cause mildew and items to get wet in your office

If the windows are leaking when it rains, they need attention, repair or replace. Other Hometalkers are correct, this can cause mold to grow and create a hazardous environment. If the water gets into the electrical outlets and wiring it could cause a short and there is a potential for fire. Is there a building inspector that comes through?

In the meantime, remove any thing that can be damaged from the window sills...paper& electronics.

Since there is no one to repair or replace windows, could this be handled by the office manager where they have the repair done and deduct it from the rent? There has to be some recourse or way to reach the property owner or management company.

Can the office be relocated?

You did not mention where the water comes from, the top or the bottoms of the windows and if it only happens when it rains. The reason I point this out is because if those are metal frames and sills the water could be condensation and not necessarily a leak. Those do not look like double or triple pane glass. When the warm inside temperature hits the cold glass it condenses on the inside. If that is the root of your water problem the only remedy is to replace the windows with wood frames or put heavy window dressing to keep the inside heat off of the glass. Perhaps you can take advantage of an energy tax credit by replacing the windows.

Hi there I agree with the caulking idea - hopefully whoever is responsible for those windows will take care of them soon for you.

In the meantime I'm wondering you could run plastic window boxes along your sills to catch the drips? Something you could easily empty etc.

Try caulking first. Add a dehumidifier to remove moisture. Also a DampRid bucket.

Can you add a drain that will run the water to a catch area?

If you go towels, microfiber will take up less space and not be as obvious.

However, I would only use these as a short term solution.

Seems to me whoever owns this building or rents units out in it is responsible for building maintenance. You should keep pursuing that avenue as it's a larger issue than the water coming in. It may be more than the windows that are leaking. If you can access the windows from the outside, caulk all around them. And ideally in the meantime, search for a new office space.

Do you own or rent this? If you rent then contact your landlord. If you own it check this out:

I agree with everyone. They need to be caulked but from the outside. The flashing on the outside may be inadequate or damaged. Could be the windows were installed incorrectly. Water is also getting inside the walls and can cause mold growth but also further damage the framing over time.

Have you traced down where the windows are leaking? It definitely needs to be caulked and flashing checked. Can you get in contact with the owners of the building? It may be causing a mold problem as well. Do you have insurance? Call them for help.

Thinking more about the wetness, is it only during rain that there is water puddling on the window sills or when it is colder outside and the air is warm in your office? That could cause condensation on the windows and the water to pool. You might consider a dehumidifier to remove some of the moisture. A fan could also help circulate the air if it is a condensation problem.

We don't know if window seal is leaking or it is from condensation like hot sun vs air conditioner on the other side.

If it is leaking you need to seal with new caulking. If it is condensation, here are a number of ways you can cut down on the humidity you create in your home. Some ways to reduce air moisture include using a portable dehumidifier or installing a whole-home dehumidifier. When you’re cooking, cover pots and pans in an effort to keep excess humidity contained and be sure to run the kitchen exhaust fan while cooking. The same goes for bathroom fans. Leaving the bathroom fan on during and after a shower will help circulate humid air out of your home. Lastly, leaving interior doors open will help allow good air circulation, so humidity doesn’t build up in one space.

Move electronics onto a shelf or far enough away from the window or you will be spending a lot more replacing them than fixing the windows.

You could probably DIY something along these lines by using some fabric sewn into logs that fit your windowsill. I guess you could fill with just rice. Not sure how well DIY version would work but you'd better customize it for blending onto the background that way?

Hello, Use a silicone sealant all around the windows. If you still have a problem, use Damp collectors boxes. (very cheap to buy)

You could get clear waterproof tape and tape all the seams up it’s clear
