Basement Waterproofing in Cambridge
Keep your finished Cambridge basement dry with proper waterproofing before and after the reno.
There's no point finishing a basement that leaks. We address moisture and water issues first — interior drainage, sump systems, and crack repair — so your investment stays dry.
What's included
- Moisture and water-source assessment
- Interior perimeter drainage
- Sump pump and battery backup
- Foundation crack repair
- Vapour barriers and proper insulation
Our process
- Design & assess — we review your space, moisture history, and goals, then plan the layout and budget.
- Permits & prep — we handle permits, moisture control, and framing so the finish lasts.
- Build — framing, electrical, plumbing, insulation, drywall, flooring, and finishes by licensed trades.
- Walkthrough — we finish clean and walk the space with you before final sign-off.

Frequently asked questions
Should I waterproof before finishing?
Always — it's far cheaper to solve moisture now than to tear out finished walls later.
Do you install sump pumps with backups?
Yes, including battery backups so the system keeps working during a power outage.
