We design, fit, and look after whole-house dehumidifier and fresh air systems for Folkestone homes, from converted Victorian villas on the Leas to harbourside cottages cut into the cliff in the Old Town and Bayle. No portable appliances to empty. No mould spray that never quite works. Just a home that's properly dry.
Our Guarantee
We take a humidity reading in your home before we switch the system on, and again 3 days after installation. If you can't see and feel the difference, and the numbers don't back it up, we'll make it right.
Folkestone is built on a steep chalk escarpment down to the harbour, and that shapes the housing stock in ways flatter towns don't share. Up on the Leas, grand Victorian and Edwardian villas and former hotels, built to look out over the Channel, have mostly been carved up into flats. Several households now share one roofline, one stairwell and often one boiler, so moisture generated in a ground-floor kitchen can end up as condensation on a top-floor window that has nothing to do with where it came from.
Down in the Old Town and the Bayle, some of the oldest buildings in Folkestone are cut directly into the hillside, with lower-ground rooms sitting below street level and retaining walls holding back the slope behind them. Groundwater moving through the chalk keeps these walls persistently damp from the outside, on top of whatever's happening indoors, and a lot of these properties are too old or too characterful for a straightforward damp-proof course.
A dehumidifier bought online treats one room in one flat. It doesn't touch a shared Victorian conversion's stairwell-wide moisture problem, and it does nothing for a hillside cottage fighting groundwater through its own walls. A whole-house system, sized and commissioned for your specific property, does.
Britain's a damp country. Always has been. But add double glazing, cavity wall insulation, and a house full of people showering and cooking — and you've got a real problem. Most homes just weren't built for it.
Wiping condensation off the glass. Cold, damp walls you try not to touch. It's not just annoying — it's a sign something bigger is going on.
You spray it, you paint over it. It's back in six weeks. That's because the spray treats the surface — not the cause.
Dust mites love a damp home. If someone in your household is struggling with their breathing or skin, high humidity is very likely making it worse.
Wallpaper peeling, plaster crumbling, timber going soft. Leave damp long enough and it stops being an inconvenience and starts being expensive.
Filtered outdoor air drawn into your home
Removes pollen, dust mites, pollutants
Refrigerant system extracts excess moisture
Clean, dry air delivered to every room
It's not a product off a shelf. Every Dryzen system is designed around your actual home — the layout, the age, what's causing the damp. Then we fit it. Then we look after it.
Every installation starts with a free survey — proper measurements, not a quick glance. We design something that fits your house, not a standard template.
One central unit in the loft. Ducting to every room. No appliances to drag around or empty. It just runs quietly in the background, getting on with the job.
Alongside the dehumidifier, we bring in filtered air from outside. CO₂ drops, allergens drop, that stuffy feeling goes. Most people notice it within a week or two.
We're talking 25 dB — quieter than a whisper. Most customers say they forget it's running. Until the windows stop steaming up, anyway.
We don't just drop the kit off. Our engineers install everything, set it up, and come back every year to service it. You don't need to do a thing.
Damp air costs more to heat — most people don't realise that. Get the moisture sorted and your boiler doesn't have to work as hard. Some customers do see a real difference on their bills.
You choose the humidity level you want. The system monitors it continuously and adjusts itself automatically to hold it there — no dials to fiddle with, no manual switching on and off.
It's pretty straightforward, to be honest. We come to you, design something that fits, fit it, and keep it running. Here's the detail.
One of our lot comes out, has a proper look around, measures the humidity in each room, and talks through what they find. No charge, no pressure.
We go away and design something that actually fits your home. Full quote within five working days — no vague estimates, just the actual number.
Usually done in a day or two. Our engineers work mostly in the loft, so it's less disruptive than you'd expect. They tidy up too — always a bonus.
Once a year, we come back — new filters, full check, make sure everything's running properly. That's it. You don't need to think about it.
Here's what some of the people we've helped actually said. No cherry-picking — this is the sort of feedback we get fairly regularly.
"We'd battled black mould in our bedroom for four years. Sprays, dehumidifiers, repainting — nothing worked long-term. Three weeks after Dryzen installed our system, the mould hasn't returned. The difference to our sleep quality has been remarkable."
"My daughter has asthma and our house was always damp and musty. Since Dryzen fitted the system, her symptoms have improved noticeably and she's sleeping through the night. We wish we'd done it years ago. Absolutely worth every penny."
"The installation was incredibly professional — their team were in and out in two days, left no mess, and walked me through everything. It's been eight months and the condensation on our Victorian sash windows has completely gone. Highly recommended."
