Most standard windows have two weep holes, located at the far left and right ends of the bottom exterior frame (the sill).
The majority of the aluminium window frames I've seen always have two weep holes located at each end of the window. This is of course to allow water to drain out to prevent flooding from occurring in the window. I believe that two weep holes per channel should be sufficient to provide adequate drainage for the window.

Blocking your window weep holes predisposes the window structure to water damage, rust, and corrosion ultimately reducing your window's lifespan.
The Weep Vent should be spaced at no greater than 900mm centres to meet N.H.B.C guidelines, which state, “weep holes are recommended to be sited at every 450mm maximum with at least two per opening above all windows and doors.”
For standard masonry and brick veneer walls, weep holes should be spaced a maximum of 33 inches apart on center. However, many masonry experts and the Brick Industry Association recommend a closer spacing of 16 to 24 inches for optimal moisture drainage.
Yes, a shower, sink, and toilet can absolutely share the same vent, often referred to as a "wet vent" configuration. This setup—where the sink drain also acts as the vent for the toilet and shower—is highly efficient and saves space, but it must strictly follow specific plumbing codes regarding sizing, slope, and distance.
Yes, weep holes can cause leaks, but usually only if they are blocked, incorrectly installed, or overwhelmed during severe weather.
While old windows might still be functional, there's a good chance they're not very efficient. Windows that are over 20 years old should be replaced. If you've lived in your home for decades and have never replaced the windows, they are likely original to the house.
If the weep holes in retaining walls are correctly spaced, this can avoid the buildup of water in the soil behind the wall. Weep holes are usually spaced every 4 to 4 feet. The weep hole size in retaining walls is usually 2 to 4 inches in diameter, depending on the type of soil used and the water volume.
While the first thought may be, “Won't those little holes let cold air in (or warm air out), the reality is these are the window's weep holes. They are designed and placed to drain water out of the window frame, while preventing airflow into your new pole building.
The cheapest time of year to replace windows is during the off-season, which runs from late fall through winter. Demand drops significantly during these months, prompting manufacturers and contractors to offer steep discounts and special promotions to keep their crews busy.
Cockroaches and spiders can come in through these higher weepholes and they are also a favourite entry point for bees and wasps. So to prevent pest entry to a building, weep holes at all levels need to be protected.
Ditching shades has a lot of upsides regardless of who you are. Uncovered windows bring in natural light, boost well-being, and offer a view of the world outside. The trade-off, of course, is that they also put those inside on display to passersby, and in the summer, they channel heat.
Fixed Windows:
Since these windows do not open, they are less likely to allow water infiltration, eliminating the need for weep holes.
Layered window treatments remain a defining trend in 2026, but the focus has shifted toward creating greater visual depth and flexibility within a space. By combining multiple window coverings, homeowners can achieve dynamic light control while adding dimension to otherwise flat architectural surfaces.
In many cases, it is cheaper to replace all windows at once. Full-home projects usually qualify for better per-window pricing because of manufacturing efficiencies, a single installation cycle, and lower labor per unit. You also avoid future price increases and start saving on energy bills sooner.

The average lifespan of windows depends on several factors, including the materials used, climate conditions, and how well they're maintained. Wood windows last 15–30 years, aluminum windows 15–30 years, vinyl windows 20–40 years, and fiberglass windows 30–50 years.
Weep holes are commonly used by snakes for a shelter site over winter! The weepholes lead to the cavity between the outer brick layer and the internal wall of the house.
This research demonstrated that even under truly extraordinary conditions water rarely enters the weephole and even if it does it cannot be blown high enough up in the cavity to create internal damp problems. To understand why, it's important to look at the details of a correctly constructed cavity wall.
Yes, a one-time water leak can absolutely cause mold. Mold spores exist naturally everywhere; if they land on a damp, porous surface (like drywall, wood, or carpet) and the moisture isn't removed quickly, mold can begin to germinate and grow within 24 to 48 hours.
Pouring salt down your drain at night is a popular DIY plumbing trick used for routine maintenance. The goal is to take advantage of the salt's coarse texture and natural moisture-absorbing properties.
In plumbing, the "135-degree rule" is a code standard that dictates how much a horizontal drain pipe can bend or change direction. It limits the total cumulative angle of pipe fittings before a system requires an access point (cleanout) or must be vented, ensuring proper flow and preventing chronic clogs.
Yes, Dawn dish soap can help unclog drains, but primarily only for minor blockages caused by grease, soap scum, or oily residue in kitchen and bathroom sinks. Its powerful degreasing properties work to break down the fats causing the restriction, especially when paired with hot water.
