Your questions, answered
How long does a waterproofing project take?
Most waterproofing projects in North London take 7–14 working days from strip-out to handover, depending on size and finish. We'll give you a clear timeline with your fixed-price quote.
Do you handle everything in-house?
Yes — plumbing, electrics (Part-P), tiling, decorating and waste removal are all handled by our own team. One contract, one project manager, no chasing trades.
Can I see designs before I commit?
Absolutely. Our designer visits your home for free, takes detailed measurements and produces a 3D visualisation before you commit to anything.
What guarantee comes with waterproofing?
Waterproofing from Norvex carries a 2-year workmanship guarantee, plus full manufacturer warranties on suite, tiles and electrics.
