Question 1

How do I thaw frozen pipes safely?

Accepted Answer

Frozen pipes are a serious winter emergency in Ottawa, and acting quickly — but carefully — can prevent a burst pipe and thousands of dollars in water damage.

First, locate the frozen section. Turn on the faucet the pipe serves. If little or no water comes out, trace the pipe back toward exterior walls, unheated spaces (crawl spaces, garages, under cabinets on outside walls), or anywhere insulation may be lacking. These are the most common freeze points in Ottawa homes during our harsh winters.

Question 2

What pipes are most likely to freeze?

Accepted Answer

Pipes in unheated areas like crawl spaces, basements, and exterior walls are most vulnerable to freezing, especially those made of copper or PEX that carry water rather than drain waste.

Location is the biggest factor in pipe freezing risk. Pipes running through uninsulated crawl spaces, unheated basements, or within exterior walls face the greatest danger. Kitchen and bathroom pipes on outside walls are particularly vulnerable, especially if there's inadequate insulation behind them. Pipes in

Question 3

Should I leave faucets dripping in cold weather?

Accepted Answer

Yes, leaving faucets dripping during extremely cold weather can prevent frozen pipes, but it's only necessary when temperatures drop well below freezing for extended periods - typically when it's colder than -15°C overnight in Ottawa.

When to let faucets drip: Focus on faucets connected to pipes in unheated areas like exterior walls, basements, crawl spaces, or garages. You only need a very slow drip - about one drop every few seconds. This small amount of moving water prevents ice formation th

Question 4

Can pipes freeze in one night?

Accepted Answer

Yes, pipes can absolutely freeze in just one night if temperatures drop low enough and the pipes are in vulnerable locations. In Ottawa's climate, this is a real concern during our harsh winter months.

How quickly pipes freeze depends on several factors. Exposed pipes in unheated areas like crawl spaces, basements, or exterior walls can freeze when temperatures hit -6°C to -10°C for several hours. The smaller the pipe diameter, the faster it freezes - half-inch copper pipes are particularly vul

Question 5

How do I know if my pipes have frozen?

Accepted Answer

Frozen pipes typically show clear warning signs: no water flow from faucets, unusual sounds in walls, or visible frost on exposed pipes. The sooner you identify frozen pipes, the better chance you have of preventing them from bursting.

Water flow issues are usually the first sign. Turn on faucets throughout your home - if only a trickle comes out or nothing at all, you likely have frozen pipes. Start with faucets on exterior walls or in unheated areas like basements, crawl spaces, or garages, a

Question 6

When should I shut off my outdoor water in Ottawa?

Accepted Answer

You should shut off your outdoor water by mid to late October in Ottawa, typically before the first hard frost which usually occurs between October 15th and November 1st. The key is to complete this task before nighttime temperatures consistently drop below -2°C (28°F).

The timing is critical because Ottawa's climate can bring sudden temperature drops in fall. Even a brief freeze can cause water in outdoor pipes and faucets to expand, leading to burst pipes and costly repairs. Once water freeze

Question 7

What is the cost of frozen pipe repair?

Accepted Answer

Frozen pipe repair costs in Ottawa typically range from $200-$800 depending on the extent of damage and location of the pipes. If the pipes haven't burst, thawing services usually cost $200-$400, but if freezing caused pipe bursts, repairs can reach $500-$1,500 or more.

Simple thawing services are the most affordable option when pipes are frozen but haven't burst yet. Licensed plumbers use specialized heating equipment to safely thaw pipes without causing damage. This typically costs $200-$400

Question 8

How do I protect outdoor plumbing in winter?

Accepted Answer

Protecting outdoor plumbing from freezing is essential in Ottawa's harsh winters - frozen pipes can burst and cause thousands in water damage when they thaw in spring.

Start with your outdoor faucets and hose bibs. Disconnect and drain all garden hoses completely, then store them indoors or in an unheated garage. Even a small amount of water left in a hose can freeze and back up into your home's plumbing. Next, shut off the interior water supply valve to each outdoor faucet - these are typicall

Question 9

How do I prepare my plumbing for winter in Ottawa?

Accepted Answer

Start winterizing your Ottawa plumbing by mid-October to prevent costly freeze damage during our harsh winters. The key is protecting exposed pipes and ensuring proper drainage before temperatures drop below -10°C consistently.

Indoor pipe protection is your first priority. Insulate any pipes in unheated areas like basements, crawl spaces, garages, and along exterior walls. Foam pipe insulation from hardware stores works well and costs under $50 for most homes. Pay special attention to pipes ne
