"Noticed a crack a few years ago, this year noticed it was bigger. Got 2 estimates. Not only was Locktight a better price, but the estimate was prompt, the guys worked fast and efficiently, nearly no disturbance to the area. Dug down (by hand!!) identified the broken elbow fitting in pipe, replaced it, waterproofed and sealed crack. Super professional. Would highly recommend."

Clay drain tile removal. FACT: With WNY being an older development in most areas, clay drain tile was used in the basements to lower the water table. Over time, clay deteriorates which leaves you with cracked, broken and defective drain tile. This leads to water backing up into your basement causing mold, mildew & damage to your foundation.

LockTight does it right by calling before we dig. We hand dig to protect your lawn, sidewalk, landscaping and underground utilities.
