Basement Window Leaking Problem? Window Wells Can Help
Window installations in a basement are great for natural light and ventilation, but improperly draining window wells can spell disaster during heavy rains. Due to improper grading and lack of waterproofing, rainwater can start to collect around foundation walls and leak through the window frame. Then, in no time, your basement starts to flood, and we all know the horrors of a leaky basement.
The solution: properly waterproofed window wells! Plus, correctly installed window wells allow for a larger basement window installation, better ventilation, and more natural light in your basement. Essentially, window wells are recesses in the ground that are dug around the foundation walls to help you install windows below the ground. However, more than replacing a window well alone is needed to solve the problem of a leaky window seal. When combined with a properly waterproofed foundation wall and vertical drainage system, window wells are the solution to a leaky basement window. Additionally, the weeping tile system needs to be in working order at the window wells’ base, allowing the proper drainage of water collected in the well.

Benefits Of Window Wells With Drainage

Natural Lighting
A fantastic benefit to a properly functioning window well is the natural light they provide to your basement. Most basements are below the ground and receive minimal lighting, but properly installed window wells allow you to install larger window openings in your basement to get more natural light all year!

Better Air Circulation
Basements can be musty and have a very damp smell due to the walls being constantly wet, but having more oversized windows can allow for better air circulation.

Emergency Exit
Basement window wells also serve as an emergency exit for dangerous situations like fire or burglary. Installing window wells gives you enough space to exit and reach a safe place in times of crisis.

Compliance with Law
Building codes and insurance policies now require residential buildings with basement windows to install window wells for safety.
Our Interior Basement Waterproofing Process
01
The first step in a window well repair is excavation. We manually excavate the soil to the required dimensions until we reach the weeping tile system at the footings. Then, we check the weeping tile and replace it if necessary.
02
We repair any cracks in the exposed foundation wall and apply a layer of primer to the exposed walls after thoroughly cleaning them with a wire brush. We then use a rubberized membrane, a fiberglass mesh layer, and another layer of rubberized membrane.
03
A layer of plastic is then applied, followed by a drainage board installation over the plastic layer. This helps to drain ground water towards the weeping tile system and protects soil backfilling.
04
The next step is to install a fresh 4-inch vertical drain from the weeping tile to the bottom ledge of the window well opening (at grade level). This vertical drain is vital to draining the window well during heavy rains.
05
We installed the window well in the pit and fastened it to the foundation walls. Then, the window well is appropriately installed and tightly attached to the foundation walls.
06
We then put around 8″ inches of ¾” clear gravel on top of the 4” vertical drain, and the exterior of the window wells are backfilled with the native soil. We then power tamp to ensure the natural grading is recovered.

Some Kind Words From Our Customers

Going thru some old files for my rental property, I discovered a contract which Gavin had signed in Jan 2007 to repair a foundation leak in my basement. This leak had been 'fixed' multiple times by others using epoxy. Gavin explained that the only sure way to fix the leak once and for all, was to dig down to the foundation from the outside to seal the cracks, plus provide a waterproof barrier against the wall. The work was done excellently and came with a 15 year warranty. It has been 19 years and no leaks have occurred. If you want a basement leak fixed right the first time, then contact GJ MacRae Foundation Repair. Highly recommended.Posted on Google![]()

Today Gavin MacRae did thorough inspection of 2 sump pumps & battery backups which he installed in 2018 - both systems still performing well. Prior to 2018 MacRae Foundation did extensive foundation/waterproofing for us - quality of workmanship excellent. Without hesitation, strongly recommend MacRae Foundation.Posted on Google![]()

Great job. Fast response to inquiries, job done fast and professionally. Put everything around the area back in place to the point where you wouldn't even know any work was done afterwards. Would 100% recommend calling them if you have a foundation repair issue.Posted on Google![]()

Let's just say that there aren't many companies of this calibre around these days. We've been dealing with GJ MacRae for the last seven years for everything sump pump related. Seven years ago the fine folks at GJ MacRae came in and replaced our existing sump with a modern unit complete with a marine battery backup and secondary pump. We have a ton of ground water around here and when it rains our sump fires non stop. Everything has been perfect and when it came time to service our system seven years in, GJ MacRae was all over it. Exceptional service, communication price and product. It's rare to see all 3 these days. Thanks for everything Gavin.Posted on Google![]()
