Storing furniture during the rainy season is mostly about keeping water out, not about the weather in the air. In Nairobi, furniture that goes into storage completely dry, sits off the floor under breathable covers and stays in a building that keeps out rain and ground water will usually come through the short rains in good condition. Climate control earns its cost mainly for antiques, valuable wood and long stays, and it matters far more on the coast, where the air is humid all year. Two mistakes to avoid above all are packing items while they are still damp and sealing them so tightly in plastic that moisture cannot escape.
This guide explains where damp in storage comes from, when climate-controlled storage is worth paying for in Nairobi, how to prepare each type of furniture, and what to ask any storage facility before you sign.
Where damp in storage actually comes from
Mould needs moisture. The US Environmental Protection Agency advises keeping indoor humidity below 60%, and ideally between 30% and 50%, and drying wet items within 24 to 48 hours to prevent mould growth. In a storage unit, moisture usually arrives in one of four ways:
- It comes in with the goods. A sofa carried across a compound in a shower, or a mattress collected from a flat with damp walls, brings its own water into the unit.
- It comes through the building. A leaking roof, a blocked gutter or water running in under a door can soak whatever sits nearest to it.
- It rises from the floor. Furniture placed straight onto a concrete floor can draw damp up from below.
- It forms inside the wrapping. Plastic sealed tightly around a piece traps any moisture already in it. The Canadian Conservation Institute warns that airtight enclosures can develop high or unstable humidity when temperatures swing, and that cold walls and floors add to the risk.
That last point matters in Nairobi. Average daytime highs sit around 22°C to 27°C through the year, while night-time lows drop to about 13°C to 16°C, according to long-term averages from the climate data service Weather Spark. A piece wrapped airtight goes through that swing every day.
Does furniture storage in Nairobi need climate control?
For most household furniture stored in Nairobi for a few months, climate control is not essential. The air in Nairobi is rarely muggy. Weather Spark’s averages show Nairobi almost never reaching a dew point above about 18°C, the level it treats as muggy, while Mombasa passes that level on nearly every day of the year. On the coast, humidity in the air itself is a constant risk, and climate or humidity control is worth asking for before you store anything of value.
In Nairobi, climate-controlled storage is worth considering for:
- antique or solid wood furniture, which reacts to changes in humidity
- artwork, photographs, books and important papers
- electronics and musical instruments stored for a long time
- anything you would struggle to replace, if storage will run for many months
If you search for climate-controlled storage near you, check what each facility actually offers. The term can mean different things. Ask whether the unit has humidity control, temperature control or simply ventilation, and whether anyone measures humidity inside.
Space Move describes its Nairobi storage units as clean, dry and pest-free, with goods wrapped, placed on pallets and kept off the floor, and the facility regularly fumigated. Its website does not describe the facility as climate controlled, so if you need that for a particular item, raise it before you book.
If climate control is not available or not affordable, the preparation steps below do most of the work for ordinary furniture. For a few precious pieces, another option is to keep them with family or friends in a dry, upper-floor room while the rest goes into storage.
How to prepare furniture for storage in the rains
Most of the protection happens before the lorry leaves your home.
Dry everything first
Clean each piece and make sure it is completely dry before it is wrapped. If rain catches furniture on collection day, dry it with towels and a fan before it goes into storage, and tell the crew which pieces got wet. A damp mattress or cushion closed up for months is exactly the condition mould needs.
Upholstery and mattresses
Vacuum sofas and chairs, treat any stains, and let the fabric dry fully before it is covered. Store mattresses flat or upright in a mattress bag, and do not pile heavy boxes on top of mattresses or cushions, because the weight can crush them permanently.
Wood furniture
Wood reacts to changes in humidity. Wipe it clean and dry, cover it with moving blankets or a breathable cover, and keep it away from outside walls. The Canadian Conservation Institute recommends keeping stored items at least 10 cm away from uninsulated walls and floors.
Transit wrapping is not the same as a storage cover
Movers wrap furniture to protect it on the road. On a Space Move job, furniture is wrapped in protective blankets and stretch film before loading. Stretch film keeps out dust and light rain during the move. For a long stay, especially for upholstery, a breathable cover lets trapped moisture escape. Ask whether the stretch film stays on in storage or is replaced, and which items should have it removed.
Leave space for air
Furniture packed tightly against other furniture and against the walls traps damp in the gaps. A little space between pieces, and a raised base such as a pallet, lets air move around them.
Checking stored furniture over several months
If your furniture will stay in storage through the whole rainy season and beyond, plan at least one check. Look and smell for the early signs of damp:
- a musty or earthy smell when you open the unit
- white, grey or green spots on fabric, leather or wood
- cushions or mattresses that feel cool and damp
- drawers or doors that have started to stick
A small humidity meter is inexpensive and gives you a reading rather than a guess. If it stays above 60% inside the unit, ask the facility what it can do, or move the most vulnerable pieces. Ask in advance how access works, because some facilities need an appointment.
Questions to ask any storage facility before you sign
The answers tell you more than a brochure will. Ask for the important ones in writing:
- Has the building ever taken water from rain or flooding, and where does water drain when it rains heavily?
- When was the roof last checked for leaks?
- Are goods kept on pallets, off the floor and away from the walls?
- Is there humidity or temperature control, or only ventilation?
- Will my goods be inspected, photographed and recorded on an inventory when they arrive?
- Does the insurance cover goods while they are in storage, not only in transit, and does it cover damp or mould damage? What does it exclude?
- How often is the facility fumigated?
- How do I get access to my things, and how much notice do you need?
The insurance question is worth pressing. Cover in storage can differ from cover in transit, so do not assume damp or mould damage is included. Ask for the cover in writing and read the exclusions.
Write a moisture and condition record at collection
Before wrapping, photograph upholstery, wooden joints, drawer fronts and the underside of furniture where practical. Record existing marks and whether any item has recently been exposed to water. Tell the storage provider about a damp smell even if there is no visible mould. Wrapping can conceal a problem without resolving its cause.
If an item is wet, pause its storage preparation and discuss suitable drying or specialist cleaning. Do not place a damp cushion in the middle of an otherwise dry load. The storage agreement should make clear who checks incoming condition, who can authorise remedial work and how you will be contacted if a problem is discovered.
Does breathable wrapping mean leaving furniture unprotected?
No. Protection still needs to address dust, rubbing and handling. The question is whether the chosen covering is suitable for the material, its condition and the storage environment. Ask the provider to explain the approach for upholstery, polished wood and mattresses separately. One type of wrapping need not suit every item.
Should you inspect furniture when it leaves storage?
Yes. Compare it with the collection record before it is hidden by new wrapping or placed against walls. Check for musty odours, damp packaging and visible changes, then record any concern using the provider’s reporting process. Allow time for this inspection rather than treating redelivery as a simple box count.
Discuss access, contracts and retrieval with the storage team. If storage is part of a house move, include collection and redelivery in the written scope. Discuss suitable preparation with the packing team before the goods leave your home.
Storing furniture with Space Move this season
Space Move’s storage facility is on Kiambu Road. Storage runs on monthly terms with a one-month minimum, and the house moving team can pack your furniture and load it straight into a unit in one booking. Request a current written storage quotation rather than relying on an old advertised starting price. The actual price depends on how much space your goods take up and how long you store them.
When you ask for a quote, list the pieces that need the most care, such as solid wood, upholstered furniture and mattresses, and say how long you expect to store them. That is the moment to ask about covers, climate control and storage insurance for those items.
