What your neighbors say

★★★★★

"When I originally contacted Luis, proprietor of NorthBay Fence Builders, he came out that same day. Within a week, I had a new fence. Not only was he professional but his workers were, too. I highly recommend NorthBay Fence builders. The price was affordable, the craftsmanship was impeccable and the professionalism was on point!!!"

Retaining Walls questions

In most North Bay jurisdictions, walls over 3–4 feet or walls supporting a surcharge require permits and sometimes engineering. We handle all of it — it's part of the job, not an extra headache for you.
Almost always drainage. Water builds up behind the wall and pushes it over. Every wall we build includes proper backfill and drainage, because a wall without drainage is just a countdown.
Yes — it's one of our most requested builds. We design the footing to carry both, so you get grade control and privacy in a single clean structure.
Built with proper drainage, timber walls typically last 20+ years and block or segmental systems 50 or more. The wall itself rarely fails — skipped drainage does. We don't skip it.
It depends on height, length, soil, and access — factors we can only assess by standing on your slope. The on-site visit is free, and you'll leave it with real numbers for your actual site.
