Exterior Basement Waterproofing in Welland – Protect Your Home with Niagara’s Trusted Experts

A wet basement can cause structural damage, mold development, and expensive repairs, not only a nuisance. The most practical long-term fix is Exterior Basement Waterproofing in Welland or the Niagara Region by McDowell Drain & Waterproofing, having 45 years of reliable experience.


Why Exterior Basement Waterproofing is the Best Solution

Unlike interior fixes that only manage water after it enters, exterior waterproofing stops moisture at its source. Our proven methods include:

✅ Excavation & Waterproof Membrane – A durable barrier applied to foundation walls.
✅ Exterior Drainage System (French Drain) – Redirects water away from your foundation.
✅ Proper Grading & Downspout Extensions – Prevents pooling near your home.
✅ Sump Pump Installation (if needed) – Extra protection against heavy rainfall.

Signs You Need Exterior Waterproofing

·         Water seeping through basement walls

·         Persistent dampness or musty Odors

·         Cracked foundation walls

·         Water pooling near your home’s foundation

·         Failed interior waterproofing attempts
