Are you dealing with water coming through walls, damp patches, or a musty basement smell? It’s not something to ignore. Left untreated, these problems can lead to expensive repairs, structural issues and mould that affects your health. At APP, we’ve been protecting homes in Cambridgeshire and East Anglia since 1967, and we’re still here doing it today.
Even though our commercial projects have grown, we’re not stepping away from residential work. Far from it. We believe homeowners deserve the same expert service, transparent advice, and long-lasting results we give to big developments.

Why Waterproofing Matters for Homes
Water gets in where it shouldn’t. Cracks in walls, failed membranes, blocked drains, rising damp, poor ventilation. All of these let water in and keep it trapped. And when that happens, you’re looking at things like:
- Mould on walls or ceilings
- Flaking paint or bubbling plaster
- Wet rot in timber
- That damp smell you can’t quite place
- Health issues triggered by mould spores
- Cold, damp rooms that never feel dry
Whether it’s a basement that’s never been dry, or a house that’s started showing signs of damp, we can fix it—and stop it from coming back.
Typical Residential Waterproofing Problems We Solve
We’ve seen it all. From period homes with rising damp through solid brickwork, to newer properties where poor drainage causes water ingress in basements. Below are some of the common calls we get. If any of it sounds familiar, don’t wait for it to get worse. Get a survey booked.

What we do
Waterproofing Built for Homes
Just because you’re not a property developer doesn’t mean you should get second-best. Every residential project we take on gets the same sharp thinking and technical know-how we bring to large-scale builds. No commission-based selling. No off-the-shelf solutions. Just proper waterproofing that’s built to last.
Cavity Drain Membrane Systems
Great for basements and below-ground rooms. These control water and direct it to a drainage point or sump pump.
Sump & Pump Systems
Essential where water needs to be mechanically removed from a basement or cellar.
Tanking Systems
We seal walls and floors to stop water coming through, perfect for retrofit or during renovations.
Waterproof Render & External Sealing
Exterior coatings and detailing that stop water before it gets in.
Extensions
Building a basement or new room below ground? We can waterproof it from the ground up, including dual systems for warranty compliance.
