How do I prevent my basement from getting wet?

Protecting your basement from water leaks or flooding starts with identifying water intrusion sources and installing a high-quality basement waterproofing system. Your system should be tailored to your home's individual needs and may include waterproofing products such as an interior drainage system and sump pump. Learn more about how you can prevent water in your basement.

How can I make a damp basement dry?

When it comes to keeping your damp basement dry, installing a dependable basement waterproofing system is key. An interior drainage system and sump pump work in tandem to keep water out of the basement and away from your foundation while a dehumidifier keeps the air dry and prevents condensation from forming on walls, ceilings, and windows. Learn more about how to make a damp basement dry.

How do I fix a leaky basement foundation?

There are many foundation waterproofing methods and products available to prevent water intrusion. However, most water problems can't be solved with a single product or treatment. Working with a reputable waterproofing company is the best way to ensure the basement waterproofing systems that best suit your specific needs are installed. Learn more about how to fix a leaky basement foundation.

How do I get rid of mold and musty odors in my basement?

Mold and mildew thrive in dark, moist environments where organic materials are present, such as a basement or crawl space. Fixing water leaks and protecting against future moisture intrusion with a reliable waterproofing system, as well as keeping the air dry with a dehumidifier, prevents mold growth and odors in your basement. Learn more about how to get rid of mold and musty odors in the basement.

How can I warm up a cold basement?

You can make your basement feel more comfortable and reduce your home heating and cooling costs by insulating your basement. There are many different types of basement insulation to choose from, each of which offers different benefits. Learn more about how to warm up a cold basement.

Project in Boulder

Our current sump pump system is quite old and looks in need of replacement. We'd like to update to a system that includes a battery backup and would like to assess whether the pit also needs to be replaced or just the pump.

Project in Boulder

We've started to have water seeping through vinyl panels over our foundation. Need this looked at and recommendations.

Project in Boulder

I have a room off of my garage (under the front porch) that has some water penetrating into the space. I need it waterproofed (caulked and any of the other stuff you all do) from the inside of the room.

Project in Boulder

Water seeped into a part of our basement after the recent heavy rain. Had never happened before.

Project in Boulder

Water getting into basement in corners & where walls meet floor

Project in Boulder

Install a sump pump to avoid underground water from entering the basement in the relatively wet season

Project in Boulder

Sump pump itself appears to be working fine, though it looks older than it is and covered in sediment, so maybe it should be cleaned/serviced. Check valve may need replacing, we hear water run down it after the pump runs for 10 seconds, but pump doesn't cycle too frequently so it must not be too much water that returns. There is a very strange gurgling sound though that continues for around 30 minutes after the pump runs though, which is mysterious. The pump discharge point is super jenky and freezes up when it gets cold out, looking for a solution for that. The sump pit does not have a sealed cover and we would like to add one that prevents radon gas from escaping while allowing it to still work as a floor drain. Finally, we don't have a tile drain system, and wondering if we should and what that would cost. The sump liner is old corrugated metal and maybe eventually needs replacing, want to understand what kind of an effort that is. Thanks!

Project in Boulder

New basement window seems to not have adequate drainage as water is pooling in window well. During heavy rain, water is seeping into basement where the floor meets the wall under the window.

Project in Boulder

We are having trouble with water piling up in our window well, and we think that installing a drainage system would help

Some moisture gathering along cove joints in basement after heavy rain. Already have a sump pump and drain tile system.

Project in Boulder

We are buying a home that has a lower level door/landing that has a drain to a French Drain on the landing that is either plugged or just cannot handle downpour situations. Current owner has a sump pump on the landing over the drain to pump water to yard if drain backs up but we would like to put in a pit/pump such that water directly flows in the pit (to the side of the door) and gets pumped out to ensure no flooding could occur with water flowing into the lower level door/room

Project in Boulder

I've had flooding before in my basement condo and want to know how much a sump pump installation in the concrete block (no vapor seal) would be. Thanks!
