We are a professional construction company that repair exterior basement walls and waterproof them. If you've got an area that leaks water we come along and hand excavate the outside, repair and waterproof the area needed, service the weeping tile system and add drainage material. And reinstate as existing. Price is $1500 per 3 linear foot of wall. Typical repairs range from 9-12k but vary depending on location, access, ground conditions and so on. Let us know if you need our help. We will be in touch.
