Disinfection in Sarkandaugava

Housing, medical complexes and production near the port — three classes of property with three different sets of requirements.

Three classes of property in one district

In Sarkandaugava we come out to flats in pre-war timber and masonry houses, to blocks of flats, to the ancillary premises of care and medical complexes, and to production and warehouse properties on the port side. We do mould removal, odour removal, ozone treatment and disinfection after flooding, a sewage failure or long vacancy.

These three classes differ not in method but in how the work is arranged. In a flat we agree with the owner. In an institution — with the person responsible for the premises, around the institution's routine. In a production plant — according to the site's access rules. Say in your enquiry which of the three we are dealing with.

We have no premises and no staff in the district. We travel out on request; in Riga travel is included in the price.

Pre-war houses and cellars

In the old houses here both classic mechanisms occur. In a timber structure the moisture rises from the ground through the bottom log courses and the damage starts at floor level. In a thick masonry wall the moisture accumulates and is released slowly, so the patch appears in the coldest corners and behind furniture during the heating season.

1The cellar under the buildingIn old houses the cellar is often low, cool and poorly ventilated. A smell on the ground floor frequently comes from there through the floor structure rather than arising in the flat itself.
2Disused chimney fluesOnce the stove has been taken out and the flue opening bricked up, the draught that provided constant air exchange for decades is gone. It is one of the commonest reasons condensation suddenly appears in an old house.
3Low ground near the waterIn lower-lying spots the groundwater level can rise in spring. Whether that affects your building shows in the state of the foundations and the cellar — it has to be checked on site, not assumed.

Being near the water and the port does not in itself mean the building has a problem. It only means the cellar and the basement level are worth inspecting separately from the living part. On that: mould in the cellar and after flooding.

Care and medical properties

The district has medical and care complexes. There we work with premises — ancillary rooms, corridors, washrooms, stores — and the work is planned around the institution's internal routine. We make no claims about treatment of illness and none about health effects; our work is sanitary treatment of premises.

  • Agree the day and the hours with the person responsible for the premises in advance.
  • Tell us how long the space can stand empty and when it is used again.
  • Say whether equipment that must not be treated stays in the room.
  • Give the area to be treated in square metres.
  • Find out the access and pass procedure for the site.

Production and premises near the port

In industrial properties the area to be treated is usually large, so we price by square metre. The typical tasks there are a smell after stored goods, damp on unheated external walls, and the state of things after a leak. Access has to be arranged in advance — many sites have their own procedure.

After a leak the sequence matters: the structure has to dry first, and only then treatment. If we treat material that is still wet, the result does not hold. We say that before the work, not after.

We work the same way in the neighbouring districts: Ciekurkalns and Vecmilgravis.

The order of work after a leak

Stop the water source

While the water keeps coming, everything else is pointless.

Take out absorbent materials

Wet insulation, cardboard and carpet do not dry inside a structure.

Dry the structure

The longest stage; in thick masonry it is measured in weeks, not days.

Inspect and measure

We measure the moisture and establish how large an area really has to be treated.

Treat and hand over

We do the work and say how long the space has to stay empty and be aired.

This sequence is the same in a flat and in a production space. Only the scale differs, and how long the structure takes to dry: a thin partition dries in days, thick old masonry in weeks.

What to prepare before we arrive

Preparation is the only part you can do yourselves and it saves time on site. Most of it is simple, but if it is left until we are already there, the work drags on.

  • Clear access to the walls and corners we will be treating.
  • Take boxes and belongings standing against the walls out of the cellar.
  • Pets and houseplants have to be taken out for the duration of the treatment.
  • If paint has been applied over the patch, say so — it will have to come off.
  • Tell us where a vehicle can be parked and who will let us in.

If the property has both a residential and a working part, give both areas straight away — treating both in one call-out is simpler than in two.

Where our work ends

We carry out sanitary treatment of premises. We do not install ventilation, we do not do waterproofing or drainage, we do not repair roofs or gutters and we do not replace rotten timber structures. If the inspection shows the cause is exactly there, we say so and do not offer treatment as the solution.

We also say when treatment is not needed at all. A smell from a dried-out trap or a blocked vent has nothing to do with growth, and it is solved without us. That is one of the commonest cases where somebody is about to pay for work that does not touch the problem.

Treatment only makes sense once the source of the moisture is known and the structure is dry. In every other case it is money for a single season.

Frequently asked questions

Does being near the port and the water mean the building will have mould?

No. It only means the foundations, the plinth and the cellar are worth inspecting separately. Whether groundwater affects your building shows on site — from the state of the cellar in spring and from where the wall is damp. We make no general claims about a whole district.

Do you work in institutional premises?

Yes, with premises: ancillary rooms, corridors, washrooms and stores. We plan the work around the institution's internal routine, and price the area by square metre. We make no claims about treatment of illness or about health effects.

The plant is 800 m² — how is the price calculated?

By area: 300–1000 m² is €0.70/m². Above 1000 m² we agree the figure individually. Ozone treatment €1.20/m², minimum €60. Before setting a price we need to know whether the structure is dry and whether goods remain in the space.

Not sure which treatment you need?

Describe the situation — we will tell you whether treatment is needed at all, and which one.
