Slippery Pathway? We'll Remove the Cause, Not Just the Film in Dorridge

A slippery pathway is one of those problems people live with for far too long, usually because it grows so gradually that each week's film of green seems barely worse than the last. Then someone slips. Algae, moss and lichen make hard surfaces treacherous when damp — which in the West Midlands is a fair portion of the year — and the fix is about more than a bucket of bleach: it is about why the surface grows a permanent green coat at all. This page explains the causes, the safe way to clean, and the repairs that stop the slip from returning.

Why pathways turn slippery

Green growth needs three things: moisture, shade and a surface it can colonise. A path under trees or beside a shaded wall, one that holds water in dips or lacks fall, or one covered in organic debris — leaves, moss clippings, bird droppings — provides all three. Tarmac and old concrete are particularly hospitable; smooth new surfaces resist better until wear opens their texture. And the slippery film is not always algae: in winter the same conditions produce an invisible-looking biofilm that is even more treacherous than obvious moss, and anything damp and shaded turns to true ice in frost. There is a diagnostic point here: growth concentrated in one area usually means water sits there, and that area will keep regrowing no matter how often it is cleaned until the water situation changes.

How we assess the problem

We look at what is growing, where and how thickly, and read that against the path's layout: shade, overhanging vegetation, and above all where water sits. We check falls and dips, any drainage that should be taking water away, and the surface's condition — because heavily weathered, spalled or cracked surfaces hold moisture in their texture and regrow faster. The assessment ends with two lists: what needs cleaning, and what needs fixing so the cleaning lasts.

Cleaning and treating the surface

Cleaning is done with the right method for the surface: pressure washing with appropriate technique for concrete, slabs and block paving — remembering that jetting block paving strips the jointing sand, which we re-sand afterwards — and gentler methods where the surface or its surroundings demand it, such as near planting or on weathered materials. Treatments to kill remaining spores and slow regrowth are applied where appropriate. We will be straightforward about chemicals: we use products suited to the surface and surroundings, but we do not guarantee chemical treatments — results depend on weather, shade and the surface itself — and where growth is heavy, more than one treatment may be needed. Debris that feeds the problem — leaf fall, overhanging growth — is worth cutting back, and we will point out what would help.

Fixing the conditions

Where our assessment shows water is sitting and feeding the growth, cleaning alone buys you a season. The durable answer is correcting the falls or dips so water drains, clearing or repairing blocked drainage, or re-laying a section that has settled into a puddle — each of which is a repair we quote before starting, with anything larger priced after survey. The combined approach — clean the surface, fix the water — is what turns a path you have to clean twice a year into one that stays clean.

Honest limits and aftercare

Shade and British weather guarantee that some green will return in time, and we do not guarantee a permanently sterile surface. What we do is remove the growth properly, treat the cause of rapid regrowth where we can, and tell you what routine care — sweeping, an occasional clean, keeping drains clear — keeps the path safe. If someone unsteady uses the path, treat recurrence seriously and get it re-cleaned rather than waiting.

Booking

You pay a booking fee when you book, and labour is charged hourly at a rate that depends on how soon you need the visit. The full cost of cleaning and any repairs is quoted and approved before we start, with materials quoted separately. When you book, tell us roughly the path's length and surface, whether it is shaded, and whether the slipperiness is everywhere or concentrated in certain spots — the pattern is diagnostic.
