☕ Sunday Morning Coffee with Matt

These quick summer downpours may only last a few minutes, but they can drop a lot of water fast.

When the ground can't absorb it quickly enough, that water can build up around your foundation and find its way into your basement. If your sump pump is running more than usual or you've noticed dampness or musty odors, it may be time for an inspection.

Stay dry and enjoy your Sunday coffee!

Saturday Mood at Thompson & Sons 😎

When the basement is dry, the sump pump is humming, and it's almost time to head home for the weekend.

Alex out here looking like he's either waterproofing a basement... or guarding a secret underground facility. 😂

Either way, the job gets done right.

Happy Saturday from the Thompson & Sons crew!
