Another basement worry checked off the list. 🙌

After years of dealing with water backing up during heavy rain, Ian called Thompson & Sons. A new stairwell drain, a new sump pump, and just a few hours later, the problem was handled.

⭐️⭐️⭐️⭐️⭐️
“Smooth and efficient from start to finish — clear communication, tidy work, and no surprises.”

That’s how we like to do it. Thank you, Ian, for trusting Thompson & Sons!

SUNDAY MORNING COFFEE TALK WITH MATT THOMPSON

Summer’s almost in the rearview mirror.

The vacations happened. The kids are heading back to school. Football is back. And somehow, September is basically knocking on the door.

But here’s the thing about basement water problems: they don’t follow the calendar.

If you noticed dampness, water, musty smells, cracks, or anything else that didn’t look quite right after this summer’s rain, don’t ignore it just because we’re moving into fall.

A small problem is usually a whole lot easier to deal with before it becomes a big one.

So enjoy the coffee. Enjoy what’s left of summer. And if your basement has been trying to tell you something, maybe it’s time to listen.

**Honesty. Integrity. Family.**
That’s how we do things at Thompson & Sons.

You know we love a happy homeowner.

Joyce kept it simple: “They did a great job for an amazing price!”

Great work. Fair pricing. No nonsense. That’s the Thompson & Sons way.

Thank you, Joyce, for trusting our family to take care of your home!

Progress is underway in Mount Washington.

Jordan and Alex have made great headway on this 82-foot interior drainage system and pump change. Every foot of drainage installed brings this homeowner one step closer to a permanently drier, healthier basement.

We're looking forward to showing you the finished result soon.
