Houses all over Donegal including Letterkenny show signs of Red Algae, but we have successfully treated dozens and dozens of them so far.

Make your home look brand new with the least amount of outlay.

Traditionally, the methods used for removing algae and the red staining associated with biomass have been extremely aggressive.

Using abrasive methods like power washing can irreparably damage plaster leaving tracks that can still be seen after painting.

Powerwashing roof tiles can altogether remove the top protective layer causing years of weathering in 5 minutes reducing the life of your roof.

Some cleaning chemicals like bleach. (hypo chloride)can void the guarantee on many modern colored plasters (K-rend, king span cladding)

Many of these methods only treat the surface while not killing the roots

Unlike bleach products ‘softwash’ solution is biodegradable.

Prokleen uses a very different approach. By getting to the root of the problem we are able to employ the gentlest of procedures and chemicals to work with nature and preserve the fabric of your home/ building. We can treat any surface and give a 100% guarantee.

Is power washing enough?

Powerwashing can be highly abrasive to some surfaces causing irreparable damage. (never use power washing to clean your roof). In moss or red algae treatment, power washing can be counterproductive, pushing the spores under slates/tiles and making them impossible to treat, allowing the immediate resumption of colonization.

There are several reasons for red algae on render. The algae blooms usually occur on walls that remain damp. This can be north-facing, leaking gutters, or just naturally shaded areas. (The typical Donegal Environment.)

A biocide works much the same as a weedkiller. When applied it takes a number of days to work. Algae-like micro weeds will reappear depending on their surroundings. We guarantee your walls to be algae-free for at least 3 years.*
