1970's house with open vents to the outside contributing to very cold floors in the house. No wear or moisture concerns. Beautiful cemented crawl space that needs proper insulation as I've also started using some of the space for storage.

We recently bought house and have noticed a musty smell near bathrooms, no leaks and smells the same upstairs as in crawl space below. Looking for someone to help us resolve this
Project Location: Duncan, BC
Hi, I originally called you to give me an estimate to level my house. I found another company to do some leveling, not so much as a project that what estimated by your estimator. I would like to have an estimate on removing the old insulation, vapour barrier, then install new vapour barrier and spray foam the inside of the foundation, up to the floor joist. This is located in a crawl space. Thank You

Hi. We have a crawl space with a concrete floor. During the winter the concrete sometimes looks damp in some places close to the exterior walls. We have never had actual water, but in weather like this it looks damp and can smell musty. Hoping you could have a look and give us suggestions and a quote. No rush. I'm sure with all this rain you are super busy right now!

I am looking at getting a quote to put some perimeter drainage around parts of my house. Though we do not have a wet basement, water has caused a corner of her house to begin to sink and we will need repair to the foundation as well.
Project Location: Duncan, BC
We have about 2 inches of standing water in our crawlspace and no clear cause. No idea how to fix this. Quote needed.

Would like someone to check our system and will probably need a new battery for our back up pump.

We have a moisture issue in our basement and crawl space - humidity/temperature issue, no leaks. I have a report from a mold inspector that I can share.
Project Location: Duncan, BC
Moisture in the crawl space and would like new vapour barrier installed correctly and also a dehumidifier installed . There is not any mold visible at this time, so for preventative measures would like this done.Just did a renovation and the contractor put in the incorrect vent for the dryer that had a scream in it and it plugged up with lint that caused moisture in the attic as the dryer took very long for closes to dry and we eventually got a error message and called about it and they said the dryer wasn't venting properly. This has caused moisture in the attic and mold as the dryer is vented through the roof. I need a professional opinion on this as well need the mold taken care of. Thank you

We did a home inspection for a house we are trying to buy, the crawl space had moisture, mould on some of the exterior joices, and they put a sump pump in, They dug a trench to allow water to get to the pump. Pump is also plumbed into the sewage system.
