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

Project Location 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. Additional information: Needs help with: Waterproofing

Project Location in Boulder

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

Water getting into basement in corners & where walls meet floor

Project Location in Boulder

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

Project Location 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!

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

Project Location 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

I have a current sump pump, but inspector said it was connected to city water and this is not allowed. I would like someone to look at it

Project Location in Boulder

We have moisture on our finished basement and we're not sure where it's coming from. It's an interior corner that has dampened baseboards and carpet. Its been going in for a while. We're looking for a company to diagnose the cause and fix the leak.

Hello, Can you tell me the thickness, R-value, and cost for $1000 sq ft of the ThermalDry® Insulated Basement Subfloor? Also, can you confirm that it is OK to use with foundations that may have moisture in the foundation, but no bulk water? Lastly, can you tell me if there is a flood event, if the subfloor can be removed and cleaned for re-use, or if it would need to be disposed? Thanks, Avery

Project Location in Boulder

900 sq ft project divided among three rooms. Will install carpeting over the subfloor -not sure which subfloor I need or if the carpet squares are enough

Basement foundation walls appear to have water seepage which is causing the concrete surface to flake off. Hoping to evaluate and find a solution. Thank you

Need sump pump installed, 1971 house that has foundation leaking

Project Location in Boulder

Our house was built in the early 70's. The previous owner gutted the finished basement. The basement remains unfinished with concrete floors and walls. During the last two snow storms, multiple snap ties have leaked, leaving a pool of water on the floor. We need the ties sealed and would like to discuss other potential issues and plans for the basement.

Project Location in Boulder

Need to get suggestions re flood mitigation. Including sump pump, landscape grading, window wells, gutters, etc.

Project Location in Boulder

We have a basement sump pump (Zoeller) that is in a pit in a closet of a bedroom. The sump pump is very noisy and we want a sump/pit that is sealed and quiet. Can you help?

Project Location in Boulder

Had a mold problem now mitigated. But source of dampness still unclear. Can you determine where moisture is coming from prior to our remodeling?

Project Location in Boulder

The water table at this property is VERY high. The current sump pump is not enough to keep the basement dry. We had problems in the Spring, and we would like a secondary sump pump installed. Can we schedule a time to get an estimate?
