Montreal has one of the widest temperature ranges of any major city in North America. Winters regularly drop well below freezing, summers can be hot and humid, and the swing between seasons is dramatic. For many household items, those conditions are harmless. For others, they are slowly destructive. Wood cracks and warps, glue joints loosen, piano soundboards split, electronics collect condensation, paper yellows and curls, leather dries and mould grows in damp fabrics.

Quick answer: NST’s climate-controlled storage in Montreal keeps furniture, pianos, art, electronics and documents in stable conditions year-round, with pick-up and delivery by our crew. Call (514) 458-7786.

Why climate control matters

Items that benefit from climate control – NST Montreal movers

Wood furniture. Wood expands and contracts with humidity. Repeated swings cause cracks, warping and loose joints, especially in antiques and fine furniture.

Pianos and instruments. Soundboards, strings and actions are sensitive to temperature and humidity. Poor storage can mean costly repairs and difficult tuning.

Art and photographs. Canvas, paper and photographic prints can ripple, crack or develop mould in damp conditions.

Electronics. Condensation can damage circuits when cold devices warm up quickly.

Documents and books. Paper absorbs moisture, encouraging mould and yellowing.

Leather and fabrics. Leather dries and cracks, and fabrics can develop musty smells and mildew.

Mattresses. Moisture trapped in mattresses can lead to mould.

Storing a piano

Pianos are among the items most affected by climate. Our piano movers wrap the piano, move it on a piano board and place it in climate-controlled storage, away from walls and vents. When it returns home, allow it to settle for a few weeks before tuning.

Storing art and antiques

Art and antiques are wrapped with appropriate materials, crated if needed and stored upright and off the floor. Climate control helps preserve finishes, canvas and paper over long periods. See custom crating for extra protection.

Montreal's climate and your belongings

Montreal experiences a remarkable range of conditions across the year. In January, outdoor temperatures can fall far below freezing, and heated homes become very dry. In July, the city is often hot and humid, and summer storms bring heavy rain. Spring and fall are full of sudden swings. Unheated storage spaces, garages, sheds and basements follow these changes closely, and some belongings suffer as a result.

Wood is the most common victim. As humidity rises, wood absorbs moisture and swells. As it falls, wood dries and shrinks. Repeated cycles stress joints and glue, crack veneers and warp panels. Pianos, guitars and violins have thin wooden parts that are even more sensitive. Paper and photographs curl, stick together or develop mould in damp conditions. Electronics can be damaged by condensation when they warm up quickly after being cold. Leather dries and cracks, and fabrics can smell musty after a humid summer.

Climate-controlled storage avoids these problems by keeping conditions steady all year, so your belongings are not exposed to the seasonal extremes that cause damage over time.

Which items really need climate control?

Not everything needs climate control, and paying for it when you do not need it is a waste. Here is a practical guide.

Strongly recommended: pianos and string instruments, antiques and fine wood furniture, fine art, framed photographs and prints, important documents and books, electronics and computers, leather furniture, vinyl records and film, wine-related collections and memorabilia.

Recommended for long periods: solid wood dining sets and bedroom furniture, mattresses and upholstered furniture, clothing and textiles stored for many months.

Usually fine in standard storage: metal furniture, plastic patio furniture, tools, sports equipment, seasonal decorations, appliances that are clean and dry, and boxes of everyday household items.

Your coordinator can help you divide your belongings so only the sensitive items go into climate-controlled space.

Storing pianos and instruments

Pianos contain a large wooden soundboard, thousands of small wooden and felt parts and strings under enormous tension. Large swings in humidity can crack soundboards, loosen tuning pins and make the action sluggish. When a piano goes into storage, our piano movers wrap it in padded covers, move it on a piano board and place it in climate-controlled space, away from exterior walls and vents. Guitars, violins and other instruments should be stored in their cases. After storage, allow pianos to settle in your home for a few weeks before tuning.

Storing art, photographs and documents

Art and paper are especially vulnerable to moisture and temperature. Paintings should be wrapped with breathable materials, stored upright and never stacked flat with weight on top. Framed works benefit from corner protection and, for valuable pieces, custom crates. Photographs and documents should be packed in sturdy boxes or plastic bins, kept off the floor and away from walls. Businesses storing archives for years should consider document storage in climate-controlled space.

Storing electronics

Electronics are best stored in their original boxes or in padded boxes, with batteries removed to prevent leaks. Before storage, back up computers and phones and clean devices of dust. After a cold-weather delivery, let electronics reach room temperature before turning them on, to avoid condensation inside.

Climate control and long-term storage

The longer the storage period, the more important climate control becomes. A few weeks in standard storage during a mild month is rarely a problem. A year that includes a full Montreal winter and a humid summer is different. If you are storing valuable or sentimental items for a long time, climate-controlled space is a small cost compared to repairs or replacement. See long-term storage for more planning tips.

Preparing furniture for climate-controlled storage

Even in stable conditions, preparation matters. Clean wood furniture with a dry or slightly damp cloth and let it dry fully before wrapping. Avoid oiling or waxing right before storage, because fresh polish can attract dust. Wrap pieces in breathable moving blankets rather than tight plastic, which can trap moisture against the finish. Remove glass tops, mirrors and shelves and store them on edge. Leave drawers slightly open or empty so air can circulate and odours do not build up. Our crews handle all of this during pick-up, so your furniture goes into storage ready for months or years.
