Premises disinfection, mould and odour removal in Riga and the surrounding region — We contact you within 5 minutes of your enquiry.

Disinfection in Ogre

A town along two rivers, on wooded and hilly ground, with a large share of older summer houses and detached homes.

What we work on in Ogre

Mould removal, odour removal, premises disinfection and ozone treatment in flats, houses, summer houses and commercial units. Ogre is very much a commuter town — many properties are lived in but empty during the day, and in practice that helps: the empty window treatment needs is usually easier to find here than in the city centre.

We travel from Riga along the A6. We have no office and no crew in Ogre. We plan the call-out around the address and the scope of work, and we state the distance surcharge before we set off.

Rivers, ground and foundations

Ogre stretches along the Daugava and the Ogre river, the ground is hilly and wooded, and the town's layout is linear — access to the northern and southern parts differs. For a specific property that yields a few concrete things to check, rather than a claim that the whole town has a damp problem.

1Where a house is built into a slopeIf a basement or plinth wall is set into a slope, water presses against it from above, down the incline. Damp then shows on one particular wall, not throughout the basement — and that is a useful signal.
2Proximity to the riverFor properties nearer the bank it is worth establishing how high the groundwater sits and whether there has ever been water in the basement. We check that on the specific site rather than assuming it from the address.
3Pine forest and shadeA house in the shade of trees dries more slowly after rain, and the north façade there can stay damp incomparably longer than the south side. That determines which wall the mould appears on first.

If the damp comes from the ground, treatment removes the growth but not the cause. We do not lay waterproofing or install drainage; if the inspection shows that without them the result will be short-lived, we say so plainly. More on the mechanism: causes of mould and mould in the basement.

If the patch is on one wall only, and it is the wall set into the slope or facing north, the cause is almost never in the room's air.

Older houses and summer houses

Around Ogre there is a substantial share of older garden houses and summer houses. Such buildings typically have shallow foundations, a ventilated sub-floor and timber structures that take up moisture and give it back slowly. If the house stands unheated over winter, the indoor air does not move and condensation settles on the coldest surfaces.

  • In spring open every room, including those shut all winter, and check skirtings and corners.
  • Check that the sub-floor ventilation hatches are not blocked with leaves or soil.
  • Run water through every drain — a dried-out trap is the most common cause of a sewage smell and is not a disinfection matter.
  • If a smell has soaked into mattresses and soft furniture, get them ready for treatment — wiping surfaces will not touch it.

For this property type: summer house treatment, long-vacant premises and ozone treatment where a smell has soaked in.

What changes in the heating season

From October to March the windows are shut and the heating is on. Moisture from cooking, showering and drying laundry stays in the rooms and condenses on the coldest surfaces — usually the corners of external walls and the space behind furniture. One load of laundry dried in a room with the windows closed releases a considerable amount of water, and it has nowhere to go.

That is exactly why the same house can look perfectly dry in summer and show patches in winter. If the patch disappears in summer and returns in winter, it is almost certainly condensation rather than a leak — and then the answer starts with ventilation and moving furniture away from the walls, not with treatment. We say that too, even when it means there is no work in it for us.

Buying a house in winter

A situation typical of Ogre: a house is bought or rented in winter, and the first spring shows what winter concealed. If you are buying an older house, it is worth looking at the basement, the sub-floor and the north façade before the deal, not just the living rooms. Traces of damp there tell you far more than a freshly painted wall on the living floor.

Inspection and work

In flats in Ogre the logic is the same as in any apartment building: the ventilation is shared, so a smell can arrive from another flat or from the basement, and then treatment in your flat will clear what has already soaked in but not the transfer. We say that honestly before the work.

Description of the property

Building type, floor area, which rooms are affected and how long the problem has been there.

Inspection on site

Moisture readings, a draught check, a look at the basement or the sub-floor. From €40.

Separating the cause

We establish whether this is condensation, groundwater or a leak — the answer differs in each case.

Treatment

We use a method that suits the material and the way the space is used.

Handover and advice

We tell you when the space can be used and what to change so the problem does not return.

If several properties along the Ogre–Ikskile corridor need inspecting at the same time, it makes sense to gather them into one call-out. That helps both the schedule and the distance surcharge.

What to prepare, and how long the rooms are out of use

In Ogre's detached-house and garden-house areas most of the time usually goes not on the treatment itself but on getting to the affected places. If that is prepared in advance, the whole job fits into one journey — and that matters, because we travel from Riga and coming back the same day is usually not practical.

  • Clear access to the walls with patches and move belongings away from the basement or sub-floor hatch.
  • Tell us whether the approach to the house is hard-surfaced — in garden-plot areas and on a slope the track after a thaw or rain is not what it is in dry weather.
  • In winter, clear the driveway and the approach to the basement hatch; some equipment we carry by hand.
  • Take house plants and pets out; if there is an aquarium that cannot be moved, tell us in advance.
  • If the property has several buildings — house, sauna, outbuilding — say at once which ones the work covers.

Nobody is in the rooms during treatment. How long they stay out of use depends on the method and the area: usually from a few hours to half a day, plus airing afterwards. We give the specific figure before the work so it can be planned around, rather than discovered on the morning.

Frequently asked questions

Do you go out to summer houses beyond the Ogre town boundary?

Yes, including the surrounding area and the Ogre–Ikskile corridor. We calculate the distance surcharge from the address; if several properties in the same direction need inspecting at once, we combine them into one call-out.

The house is on a slope and the basement is damp — will treatment help?

Treatment takes the growth off the surfaces, but if water is pressing in from the ground it is a half-solution with a limited shelf life. We say so plainly at the inspection. We do not lay waterproofing or install drainage — those are building works.

When is the best time to treat a house that stood empty over winter?

In spring, when the rooms can be opened fully and there is time for drying before treatment. In mid-summer, with people and belongings in the house, the work is harder to organise and the result is less complete.

Not sure which treatment you need?

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