Don’t let damp destroy your London property.

Once damp finds its way into a building, it will eat away at the structure and spread aggressive, reeking mould until it’s stopped. There is no quick fix, there is no way to hide it from surveyors and if you ignore it, it will only get worse.

But there is good news: in all our years of business, Environ’s never found a damp problem we haven’t been able to fix. Sometimes it’s a tough job, sometimes we find buildings so damaged that they’re no longer safe to inhabit, but no matter what, we will get rid of damp – guaranteed.

If you want to find out how we’d banish damp from your property and protect it in the future, click here to book your free, no obligation site survey and quote.

Rising Damp Treatment

How we treat rising damp

There’s only one treatment for rising damp: repairing or installing a damp proof course (DPC). It’s a difficult and costly job, so before we treat your rising damp, we need to make sure we accurately diagnose it.

Cowboy damp proofers are notorious for misdiagnosing other types of damp as rising damp so that they can charge a small fortune for DPC repair or installation. At Environ, we’ll provide you with hard evidence of rising damp before we start digging around beneath your property.

If you do need rising damp treatment, the last thing you want is for the damp to come back a few years later. At Environ, our rising damp treatment is built to last, with a 15-25 year guarantee that your damp won’t return.

Penetrating Damp Treatment

How we penetrating damp

You can’t just paint over penetrating damp and hope it goes away. If you don’t find the cause, water can eat away at your property until what could have been a quick fix becomes a serious and expensive structural issue.

There are many causes for penetrating damp, from blocked gutters or decayed pointing to broken plumbing or cracked walls. Any way that unwanted water can get into your property can cause penetrating damp.

Treating penetrating damp is part detective work, part craftsmanship. Our damp experts will first perform a free, top-to-bottom survey of your property to find what’s causing your penetrating damp, then fix it with specialist damp proofing materials and a flawless finish.

Damp Walls Treatment

How we treat damp walls

Are your walls wet to the touch but with no signs of structural damp? Then there’s probably too much moisture in the air, which settles on the walls as condensation.

Condensation is the most common cause of damp, and luckily it’s also the easiest and cheapest to fix. Simply installing a PIV unit in your property will push out the wet, stale air and keep your walls and windows dry and mould-free.

We provide the cheapest PIV installation in London and, like all our damp treatments, we include a guarantee that your damp won’t return. And with a running cost of just pennies a day, you can get rid of condensation without breaking the bank.

Whether you’re a family home or a bustling business, our damp surveys are entirely free of charge.

This survey tells you what’s causing your damp, what we can do to fix how much it would cost. Our damp experts are always happy to tour you around the property to show you what they’ve found and explain their solutions.
